  Here, a case where a smartphone or a mobile phone is used as the mobile terminal 18 is described, but an adapter (transmission / reception unit J), a touch panel, a keyboard, or the like (man machine interface Q) corresponding to Wi-Fi communication is provided. If it is a thing, a tablet terminal, a laptop personal computer, a notebook personal computer, etc. can also be utilized as the portable terminal 18.

  Next, the flowchart of FIG. 6 showing the outline of the control program installed in the SSD 35 of the control device 12 and the flowchart of FIGS. 7 to 9 showing the outline of the application program installed in the SD memory card of the portable terminal 18 are shown. With reference to this, the processing operation of the control device 12 and the portable terminal 18 constituting the remote monitoring system in this embodiment will be specifically described.

  Although there are no particular restrictions on the number of crane vehicles 1 to be monitored or the number of mobile terminals 18 used for monitoring, the identification information for identifying the crane vehicles 1 is a value unique to the control device 12 of each crane vehicle 1. It is assumed that there is no duplication, and the identification information for specifying the mobile terminals 18 is also a value unique to each mobile terminal 18 and there is no duplication.

  When the operator activates the control device 12 of the crane vehicle 1, the microprocessor 24 of the control device 12 first sets an initial value “0” in the selection status storage flag F <b> 1. It is stored that the mobile terminal 18 is not selected as a monitoring target (step a1 in FIG. 6).

  Next, the microprocessor 24 functioning as the main control unit F of the control device 12 receives signals from the undulation angle detection sensor S1, the boom length detection sensor S2, the load sensor S3, the turning angle detection sensor S4, etc. via the input / output circuit 13. The data is read (step a2), and the data is updated and temporarily stored in the RAM 23 constituting a part of the data storage means C as a series of load suspension state information (step a3).

  Next, the microprocessor 24 of the control device 12 sets the selection status storage flag F1 to a value “1” indicating that the crane vehicle 1 in which the control device 12 is installed is selected as a monitoring target by the at least one portable terminal 18. Is set (step a4).

  However, since the value of the selection status storage flag F1 is held at the initial value “0” at this time, the determination result in step a4 is false, and the microprocessor 24 further transmits from any of the portable terminals 18. It is determined whether or not the identification information is received by the adapter 27a constituting the transmission / reception unit G of the control device 12 (step a5).

  If the portable terminal 18 is not activated and no identification information is received from any portable terminal 18, the determination result in step a5 is false.

  In this case, the microprocessor 24 that functions as the main control unit F of the control device 12 receives information input by the operator via the touch panel 20 or the switch group 21 that functions as the man-machine interface B, for example, the crane operating range restriction. Processing for receiving setting information such as an area and storing it in the non-volatile memory 22 constituting a part of the data storage means C, various setting information already stored in the non-volatile memory 22 or a part of the data storage means C The latest load suspension state information temporarily stored in the RAM 23 constituting the display and displaying it on the display 19 functioning as the display means D, or via the touch panel 20 functioning as the man-machine interface B I / O circuit according to various commands entered by the operator 3 and the electromagnetic solenoids SOL1, SOL2, SOL3, SOL4, etc. of the actuator group E via the drivers 14, 15, 16, 17 and so on, and the hydraulic cylinder 9 for raising and lowering, the hydraulic cylinder for expansion and contraction, the hydraulic motor for winch, and for turning When the process for controlling the drive of the hydraulic motor or the like is executed in the same manner as in the prior art, the process for one process cycle is completed (step a14), and whether or not a work end command is input from the touch panel 20 or switch group 21 Determine (step a15).

  If no work end command is input, the microprocessor 24 functioning as the main control unit F of the control device 12 returns to step a2 again to start the next cycle, and repeats the same processing as described above. Run.

  Therefore, unless the mobile crane 1 in which the control device 12 is installed is selected as a monitoring target by the at least one portable terminal 18, the microprocessor 24 of the control unit 12 repeats the processing of step a2 to step a5 and step a14 to step a15. During this time, the latest information on the load state information input from the undulation angle detection sensor S1, the boom length detection sensor S2, the load sensor S3, the turning angle detection sensor S4, etc. is sequentially updated in the RAM 23. When various setting information including the crane operating range restriction area is input or updated by the operator, the latest setting information is updated and stored in the nonvolatile memory 22. It will be.

  On the other hand, when the work manager or the like starts the application program of the mobile terminal 18, the microprocessor 35 of the mobile terminal 18 first sets the value of the index C for storing the number of crane vehicles 1 to be monitored to “0”. (Step b1 in FIG. 7), it is determined whether or not an application program termination command is input from the touch panel 29 functioning as the man-machine interface Q (step b2). If no program termination command has been input, it is further determined whether or not an activation request for target selection processing for selecting the crane vehicle 1 to be monitored has been input via the touch panel 29 by the work manager or the like. (Step b3).

If there is no request for starting the object selection process, the microprocessor 35 of the mobile terminal 18 is an adapter in which the identification information and the setting information transmitted from the control device 12 of any crane vehicle 1 constitute the transmitting / receiving unit J of the mobile terminal 18. 36 (step b18), but since the transmission of information from the control device 12 of the crane vehicle 1 has not started at this time, the determination result in step b18 is false. Whether the microprocessor 35 of the portable terminal 18 further receives the identification information and the load state information transmitted from the control device 12 of any crane vehicle 1 by the adapter 36 constituting the transmission / reception unit J of the portable terminal 18. It is determined whether or not (step b20).
As already described, since transmission of information from the control device 12 is not started at this time, the determination result in step b20 is false, and the microprocessor 35 of the portable terminal 18 further detects the crane vehicle 1 to be monitored. It is determined whether or not the current value of the index C that stores the number of vehicles is “0” (step b22).

  At this stage, since the current value of the index C is held at the initial value “0”, the determination result in step b22 is true.

  Therefore, the microprocessor 35 of the portable terminal 18 returns to step b2, and repeats only the processing of step b2 to step b3, step b18, step b20, and step b22 in the same manner as described above.

Here, when a work manager or the like inputs a request for starting the object selection process via the touch panel 29 functioning as the man-machine interface Q, this operation is detected in the determination process in step b3, and the microprocessor of the portable terminal 18 35 again initializes the value of the index C for storing the number of crane vehicles 1 to be monitored to “0” (step b4).
Here, the value of the index C is initialized to “0” again even after all the crane vehicles 1 to be monitored are selected and the monitoring work is started. This is because the object selection process may be executed for reselecting the vehicle 1, and at that time, it is necessary to invalidate the information related to the crane vehicle 1 that has been stored as the monitoring target.

Next, the microprocessor 35 of the portable terminal 18 clears the content of the monitoring target storage table T2 for storing information related to the crane vehicle 1 to be monitored (step b5), and all the crane vehicles that can be the monitoring target. 1 information, for example, the contents of the selection candidate storage table T1 in which information of all crane vehicles 1 owned by one construction company or the like is registered in advance from the SD memory card of the card slot 38, and the display means of the portable terminal 18 A list is displayed on the display 28 functioning as K (step b6).
FIG. 10A is a conceptual diagram showing an example of the logical configuration of the selection candidate storage table T1, and the selection candidate storage table T1 includes identification information for identifying the crane vehicle 1 to be selected, that is, this information. In this case, the identification information of the control device 12 installed in the crane vehicle 1 and the names of the handles representing the crane vehicle 1, for example, the names of the first unit, the second unit, the third unit,. It is stored in correspondence.

  Next, the microprocessor 35 of the portable terminal 18 selects one of the crane vehicles 1 from the selection candidate storage table T1 listed on the display 28 by a work manager who operates the touch panel 29 functioning as the man-machine interface Q. It is determined whether or not a handle name selection operation has been performed (step b7). If the handle name selection operation has not been performed, whether or not a selection end operation has been performed by a work manager operating the touch panel 29 or the like. It is determined whether or not (step b12).

  If neither the handle name selection operation nor the selection end operation is performed, the microprocessor 35 of the portable terminal 18 performs steps b7 and b12 until a handle name selection operation or a selection end operation is detected. Only the judgment process is executed repeatedly.

Here, when the work manager or the like operates the touch panel 29 functioning as the man-machine interface Q and selects one of the handle names displayed on the display 28, this operation is determined in step b7. The microprocessor 35 of the portable terminal 18 that is detected in the process and functions as the display object selection means I stores the selected handle name and the identification information of the crane vehicle 1 corresponding to the handle name, that is, the identification information of the control device 12 as selection candidates. It is read from the table T1 and stored at the head address of the monitoring target storage table T2 (step b8).
For example, if the first selecting operation from the list display of selection candidate storage table T1 as shown in FIG. 10 (a) and the handle name H ₁ is selected, the address 1 of the monitoring target storage table T2, the identification information I ₁ and the handle name H ₁ are stored.

  Next, the microprocessor 35 of the portable terminal 18 determines whether or not a display item selection operation is performed by a work manager or the like who operates the touch panel 29 functioning as the man-machine interface Q (step b9). If the display item selection operation is not performed, the standby state is maintained as it is.

When a display item selection operation is performed by the work manager or the like, the microprocessor 35 of the portable terminal 18 functioning as the display item selection means P detects this operation in the determination process of step b9, and displays it as a display item. The type of the selected information, for example, only “operation range limited area” in the setting information, or a combination of “operation range limited area” and “other setting information”, or “loading state information” "Boom hoisting angle" only, or two items such as "boom hoisting angle" and "turning angle", a combination of three items ..., and some items of setting information and the load suspension state A combination of several items of information is associated with the above-described identification information and handle name as display item information as the top address of the monitoring target storage table T2. Is stored (step b10).
For example, handle name H ₁ from the list displayed in FIG. 10 selection as shown in (a) candidate storage table T1 is selected by the first selection operation by the display target selection unit I, display item selected as the display item corresponding thereto if display item K ₁ is selected by means P, the address 1 of the monitoring target storage table T2, the display item K ₁ corresponding to the identification information I ₁ and the handle name H ₁ is stored.
The display items may be selected by selecting and combining individual setting information and the names of individual loading state information one by one, or several combinations of information set in advance are displayed in a pull-down menu or pop-up menu. It is also possible to use a format in which a combination is specified by presenting the combination by selecting one combination from among them.

  Next, the microprocessor 35 of the portable terminal 18 increments the value of the index C for storing the number of crane vehicles 1 to be monitored by 1 to obtain information related to the crane vehicle 1 to be monitored as the monitoring object storage table T2. Is stored (step b11), and it is determined whether or not a selection end operation is performed by a work manager or the like who operates the touch panel 29 (step b12).

  If the selection end operation has not been performed, the microprocessor 35 of the portable terminal 18 repeatedly executes only the determination processing of step b9 and step b12 until the handle name selection operation or the selection end operation is detected again. .

  During this time, the work manager operates the touch panel 29 functioning as the man-machine interface Q, selects another handle name from the list display on the display 28, and also selects a display item to be associated with the handle name. Thus, any number of combinations of identification information, handle names, and display item information can be stored following the monitoring target storage table T2 as shown in FIG. 10B, for example.

  When the work manager or the like who has finished the operation for selecting the crane vehicle 1 to be monitored operates the touch panel 29 functioning as the man-machine interface Q and executes the selection end operation, this operation is performed in step b12. And the target selection process is completed.

Next, the microprocessor 35 of the portable terminal 18 stores all of the control devices 12 of the crane 1 stored in the monitoring target storage table T2 as monitoring targets, that is, addresses 1 to C of the monitoring target storage table T2. Identification information for identifying the portable terminal 18 through the adapter 36 functioning as the transmission / reception unit J addressed to all of the identification information I _{1 to} I _C , that is, identification information of the portable terminal 18 in this case This is transmitted by multicast (step b13), and further, the crane operating range restriction area and the like are sent to all of the identification information I _{1 to} I _C stored in the addresses 1 to C of the monitoring target storage table T2. A transmission request signal for requesting transmission of setting information as the beginning is transmitted by multicast (step b14).

Next, the microprocessor 35 of the portable terminal 18 displays a plurality of screens of the display 28 that functions as the display means K in the portable terminal 18 according to the value of the index C that specifies the number of crane vehicles 1 from which information is to be acquired. Information P _{1 to} Pc that divides into areas and specifies each display area is obtained (step b15), and these pieces of information are stored as display area information P _{1 to} Pc at addresses 1 to C in the monitoring target storage table T2. Thus, the identification information for identifying each crane vehicle 1 is associated with the divided display areas on a one-to-one basis (step b16).
Next, the microprocessor 35 of the portable terminal 18 sets a value “0” indicating that the batch display mode is being selected using the display area specifying means M and the monitoring information batch display control means N as an initial value in the mode selection flag F2. (Step b17), the determination process of step b2 to step b3 is executed in the same manner as described above.

Here, FIG. 11 shows an example of a screen division state of the display 28 determined by the value of the index C that specifies the number of crane vehicles 1 from which information is acquired.
If C = 1 and the number of crane vehicles 1 from which information is acquired is one, the information selected in the display item selection process described above among the setting information and the load suspension state information of the crane vehicle 1 is, for example, It will be displayed in Figure 11 the display region P ₁ occupying a single display most of the display screen by using the display screen mode, as shown in (a).
Further, if C = 2 and the number of crane vehicles 1 from which information is acquired is two, the above-described display items of the setting information and the load suspension state information of the crane vehicle 1 selected as the monitoring target first. information selected by the selection process, are displayed in the display area P ₁ occupying half example FIG 11 (b) to utilize the display screen of the collective display mode as shown displayed on the screen, then as the monitor The information selected in the selection processing of the display item described above among the setting information and the loading state information of the selected crane vehicle 1 is displayed in the lower half of the display screen as shown in FIG. 11B, for example. It will be displayed in the region P _2.
Further, if C = 3 and the number of crane vehicles 1 from which information is acquired is three, the above-mentioned display items of the setting information and the load suspension state information of the crane vehicle 1 first selected as the monitoring target are displayed. The information selected in the selection process is displayed in the display area P ₁ that occupies the upper third of the display screen by using a display screen in the collective display mode as shown in FIG. The information selected in the display item selection process described above among the setting information and the load suspension state information of the crane 1 selected as the target is displayed in the center of the display screen as shown in FIG. It is displayed in the display area P ₂ occupying the last information selected by the selection processing of the display items mentioned above among the selected setting information and the suspended load status information of the crane 1 as monitored, for example, FIG. 11 (c) As shown in the table It will be displayed in the display area P ₃ occupying the lower third of the screen.
In addition, if C = 4 and the number of crane vehicles 1 from which information is acquired is four, the display items described above among the setting information and the load suspension state information of the crane vehicle 1 selected as the monitoring target first. The information selected in the selection process is displayed in the display area P ₁ occupying the upper left quarter of the display screen by using the display screen in the collective display mode as shown in FIG. Among the setting information and the loading state information of the crane vehicle 1 selected as the target, the information selected in the display item selection process described above is displayed in the upper right 1 / of the display screen as shown in FIG. Information selected in the display item selection process described above among the setting information and the load suspension state information of the crane 1 that is displayed in the display area P ₂ that occupies 4 and is selected as the monitoring target next is, for example, FIG. As shown in (d) Is to displayed in the display area P ₃ occupying the lower left quarter of the screen is selected in the selection processing of the display items mentioned above among the last selected setting information and the suspended load status information of the crane 1 to be monitored The displayed information is displayed in the display area P ₄ occupying the lower right quarter of the display screen as shown in FIG. 11D, for example.
The screen division format is a design problem and is not restricted by the example of FIG.

  On the other hand, the identification information of the portable terminal 18 transmitted from the portable terminal 18 in the process of step b13 in FIG. 7 is the control device 12 that repeatedly executes the processes of step a2 to step a5 and step a14 to step a15. It is detected in the determination process of step a5 in FIG. 6 by the control device 12 installed in the crane vehicle 1 stored as a monitoring target in the monitoring target storage table T2 of the portable terminal 18.

The microprocessor 24 of the control device 12 that has received the identification information transmitted from the portable terminal 18 through the adapter 27a sets the value “1” in the selection status storage flag F1, thereby installing the crane in which the control device 12 is installed. The vehicle 1 has been selected by the first portable terminal 18 that has the crane vehicle 1 as a monitoring target, that is, it is necessary to start transmitting information from the control device 12 to at least one portable terminal 18. (Step a6), and the identification information of the portable terminal 18 is stored in the nonvolatile memory 22 constituting the data storage means C as the identification information of the first portable terminal 18 to be transmitted. (Step a7).
However, even if the value “1” is set in the selection status storage flag F1, the identification information transmitted from another portable terminal 18 is detected by the microprocessor 24 of the control device 12 in the process of step a8. When a plurality of portable terminals 18 redundantly select the crane vehicle 1 on which the control device 12 is installed as a monitoring target, information is stored in the nonvolatile memory 22 constituting the data storage means C of the control device 12. Is stored (see step a4, step a8, step a7).

  In this way, the crane vehicle 1 is selected as one to be monitored by any one of the portable terminals 18, and the value “1” is once set in the selection status storage flag F1, whereby the control device 12 side step a9, step Execution of processing such as a10 and step a12 is permitted.

  Therefore, the microprocessor 24 of the control device 12 functioning as the information transmission control means H having the work information transmission function h1 firstly has the undulation angle of the boom 8, the actual length of the boom 8, the load on the load, and the turning angle of the swing body 6. The latest data of various load suspension state information including the current value is read from the RAM 23 functioning as the data storage means C, and the identification information is stored in the nonvolatile memory 22 as a target to which information is transmitted by the process of step a7. All of the portable terminals 18 are sent to the destination, and the load suspension state information is transmitted together with the identification information of the control device 12 by multicast via the adapter 27a constituting the transmission / reception unit G (step a9).

Moreover, the transmission request signal of the setting information transmitted from the portable terminal 18 addressed to all of the identification information I _{1 to} I _C specifying the crane 1 to be monitored in the process of step b14 in FIG. The microprocessor 24 of the control device 12 in the selected crane vehicle 1 is detected through the adapter 27a functioning as the transmission / reception unit G in the determination process in step a10 of FIG.

  Therefore, the microprocessor 24 of the control device 12 that functions as the information transmission control means H having the setting information transmission function h2 is a non-volatile memory that functions as the data storage means C for various setting information including the crane operating range restriction region. All the portable terminals 18 that are read from the memory 22 and whose identification information is stored in the nonvolatile memory 22 as information transmission targets in the process of step a7 are sent to and received from the destination together with the identification information of the control device 12. The data is transmitted by multicast through the adapter 27a constituting the part G (step a11).

Then, the setting information transmitted together with the identification information of the control device 12 by specifying the identification information of the transmission destination from the control device 12 in the process of step a11 is the microprocessor of the portable terminal 18 in the determination process of step b18 in FIG. 35.
Upon detecting this, the microprocessor 35 searches for the address of the monitoring target storage table T2 storing the identification information corresponding to the received identification information, and updates and stores this setting information in the data storage area of the corresponding address. (Step b19).
Therefore, for example, when the setting information D ₁ is transmitted from the crane vehicle 1 in which the control device 12 having the identification information I ₁ is installed, the setting information D ₁ is monitored as shown in FIG. stored in the data storage area D ₁ of the address 1 in the target storage table T2, also in a case where setting information Dy the controller 12 from a crane 1 installed with the identification information Iy is transmitted, the setting The information Dy is stored in the data storage area Dy at the address C in the monitoring target storage table T2 as shown in FIG.

On the other hand, the load suspension state information transmitted together with the identification information of the control device 12 by specifying the identification information of the transmission destination by the control device 12 in the process of step a9 is the same as that of the portable terminal 18 in the determination process of step b20 in FIG. Detected by the microprocessor 35.
Then, the microprocessor 35 that has detected this retrieves the address of the monitoring target storage table T2 that stores the identification information corresponding to the received identification information, and updates this loading state information in the data storage area of this corresponding address. (Step b21).
Therefore, for example, when the load suspension state information D ₁ ′ is transmitted from the crane vehicle 1 in which the control device 12 having the identification information I ₁ is installed, the load suspension state information D ₁ ′ is shown in FIG. Is stored in the data storage area D ₁ ′ of the address 1 in the monitoring target storage table T2 as shown in FIG. 5 and the load suspension state information Dy ′ is transmitted from the crane vehicle 1 in which the control device 12 having the identification information Iy is installed. In this case, the load state information Dy ′ is stored in the data storage area Dy ′ at the address C in the monitoring target storage table T2 as shown in FIG.

  Next, the microprocessor 35 of the portable terminal 18 determines whether or not the current value of the index C that stores the number of crane vehicles 1 to be monitored is “0” (step b22). Since C> 0 is inevitably present at the present time after the selection process is executed, the determination result in step b22 is false, and the microprocessor 35 further selects the single display mode in the mode selection flag F2. It is determined whether or not a value “1” indicating “?” Is set (step b23).

  Since the value of the mode selection flag F2 is held at the initial value “0” at the present time immediately after executing the target selection process, the determination result in step b23 is false, and then the microprocessor 35 of the portable terminal 18 It is determined whether or not the current value of the index C that stores the number of crane cars 1 is “1” (step b24).

  Here, when the determination result in step b24 is true and it is clear that the current value of the index C is “1”, one crane vehicle 1 to be monitored is displayed by the display target selection means I. This means that the process of the collective display mode in which information of a plurality of crane vehicles 1 is simultaneously displayed according to the current value “0” of the mode selection flag F2 set by default is meant. There is no.

Therefore, in this case, the microprocessor 35 of the portable terminal 18 has the value “1” indicating the head address of the monitoring target storage table T2 in the temporary storage register R, that is, the display target selection means I among the plurality of crane vehicles 1. The address value “1” storing information related to only one crane vehicle 1 selected by the microprocessor 35 functioning as the microprocessor 35 is set (step b32), and the value “1” of the index C is set. Then, the screen display of the display 28 is switched to the display screen of the single display mode as shown in FIG. 11A, and is divided into a display area P ₁ occupying most of the display screen and a remaining display area P ₀ (step b28). ), The microprocessor 35 functioning as the monitoring information display control means L is stored in the address R (where R = 1) of the monitoring target storage table T2. Referring to the display item information are, displays only the information items that are stored as display items of the various types of setting information and various suspended load state information of the display area P ₁ (step b29), the display area P _A command input screen is displayed at ₀ (step b30), a value “1” indicating that the single display mode is being selected is forcibly set to the mode selection flag F2 (step b31), and the processing returns to step b2. .
The command input operation performed using the command input screen and the touch panel 29 will be described later in a lump and will not be described here.

Among various setting information and various suspended load status information of the crane 1, since only the information of the item selected by the display item selecting section P is displayed on the large screen of the display area P _1, the crane 1 Workability when monitoring is improved.

  Next, the microprocessor 35 of the portable terminal 18 executes the determination process of Step b2 and Step b3 in which both determination results are false, and then the identification information and the setting information transmitted from the control device 12 of the crane 1 are It is determined whether or not it is received by the adapter 36 constituting the transmission / reception unit J of the terminal 18 (step b18), but unless the work manager or the like transmits a transmission request signal for requesting transmission of setting information from the portable terminal 18. Since the control device 12 does not automatically transmit the setting information except when the control device 12 and the mobile terminal 18 are connected for the first time, the determination result in step b18 is false.

  Therefore, the microprocessor 35 of the mobile terminal 18 further receives the identification information and the load suspension state information transmitted from the control device 12 of the crane 1 by the adapter 36 constituting the transmission / reception unit J of the mobile terminal 18. It is determined whether or not (step b20).

  At this time, as shown in FIG. 6, the microprocessor 24 of the control device 12 repeatedly executes the processing of Step a2 to Step a4, Step a8 to Step a10, Step a12, Step a14 to Step a15. In the processing of step a9, the microprocessor 24 functioning as the information transmission control means H having the work information transmission function h1 reads various load suspension state information from the RAM 23 and has the identification information to be transmitted. Since the process of transmitting together with the identification information of the control device 12 is executed every predetermined period, the microprocessor 35 of the portable terminal 18 transmits these information transmitted from the control device 12 to the step b20. As soon as it is detected in the process of, the identification information corresponding to the received identification information is stored. The information of the data storage area of the corresponding address of the visual target storage table T2, rewrites the currently received new suspended load status information (step b21), the process proceeds to the next processing.

  At this time, the value of the index C in the portable terminal 18 is C ≠ 0 (because the object selection process has already been performed), and the value of the mode selection flag F2 is “1” (the crane vehicle to be monitored) 1 is selected), the determination result of step b22 is false, the determination result of step b23 is true, and the microprocessor 35 of the portable terminal 18 further functions as a man-machine interface Q. It is determined whether or not a display mode switching operation is performed by a work manager who operates the touch panel 29 (step b33).

  Here, even if the operation mode switching operation is performed by the work manager or the like and the determination result in step b33 becomes true, as described above, there is only one crane vehicle 1 to be monitored. Since there is no point in switching from the single display mode to the batch display mode under the condition of = 1 (see paragraph 0091), such a switching action is ignored by the determination process in step b34.

Next, the microprocessor 35 of the portable terminal 18 determines whether or not a selection item switching operation is performed by a work manager or the like who operates the touch panel 29 functioning as the man-machine interface Q (step b42).
If the selection item switching operation has not been performed, the microprocessor 35 of the portable terminal 18 functioning as the monitoring information display control means L displays the display item stored at the address R (R = 1) in the monitoring target storage table T2. The display area of the display screen of the single display mode on the display 28 as shown in FIG. 11A is referred to only for information on items stored as display items among various setting information and load state information. update to be displayed in the P ₁ (step b45).

When the selection item switching operation is detected by the determination process in step b42, the microprocessor 35 of the portable terminal 18 functioning as the display item selection unit P performs the same process as in the above-described steps b9 to b10. Steps b43 to b44 are executed, and the type of information newly selected as a display item by the work manager or the like who operates the touch panel 29, for example, only the “operation range restricted area” in the setting information, or , “Operating range restriction area” and “other setting information”, or only “Boom hoisting angle” in the load suspension state information, or “Boom hoisting angle” and “Turning angle” , A combination of three types of items, and also some items of the setting information and some of the load state information The combination of items is updated to the monitoring target storage table T2 as the display item information corresponding to the identification information and the handle name of the address 1 of the monitoring target storage table T2 specified by the value of the register R (R = 1). To remember.
Then, the microprocessor 35 of the portable terminal 18 functioning as the monitoring information display control means L refers to the display item information newly stored at the address R (R = 1) of the monitoring target storage table T2, and performs various settings. only the information of the items stored by updating alone display the display area P ₁ of the display screen mode of the display 28 as shown in FIG. 11 (a) displaying a display item of information and the suspended load status information (Step b45).

Next, the microprocessor 35 of the portable terminal 18 allows a work manager or the like who operates the touch panel 29 functioning as a man-machine interface Q for inputting a command to display a display area on a screen as shown in FIG. with reference to command input screen P ₀ determines whether performing a command input operation on the touch panel 29 (step b46).

  When a command input operation is detected, the microprocessor 35 of the portable terminal 18 sends this input command to the address R (R = R =) of the monitoring target storage table T2 via the adapter 36 functioning as the transmission / reception unit J. It transmits to the control apparatus 12 which has the identification information memorize | stored in 1) (step b47).

  This input command is transmitted to the portable terminal 18 by the process of step b47 among the control devices 12 that repeatedly execute the processes of step a2 to step a4, step a8 to step a10, step a12, and step a14 to step a15 in FIG. The determination process of step a12 is performed by the control device 12 having the identification information that matches the identification information transmitted by, that is, in this case, the control device 12 having the identification information stored at the address 1 of the monitoring target storage table T2. The microprocessor 24 of the control device 12 that has detected this is processed in the same manner as when a command is input from the touch panel 20 that is the man-machine interface B of the control device 12 itself ( Step a13).

  Accordingly, the work manager or the like who has the portable terminal 18 has several actuators, for example, the hoisting hydraulic cylinder 9, provided in one crane vehicle 1 selected as the information display target and the operation target at this time. The telescopic hydraulic cylinder, winch hydraulic motor, turning hydraulic motor, etc. can be operated freely from a remote location.

Next, is the microprocessor 35 of the portable terminal 18 operated to request output of a transmission request signal for requesting transmission of setting information by a work manager or the like who operates the touch panel 29 functioning as the man-machine interface Q? (Step b48), and if there is a transmission request signal transmission request, address all of the identification information I _{1 to} I _C stored in the addresses 1 to C of the monitoring target storage table T2, and A transmission request signal for requesting transmission of setting information including the operating range restricted area is transmitted by multicast (step b49).

This transmission request signal is detected by the determination processing hand of step a10 by the control device 12 that repeatedly executes the processing of step a2 to step a4, step a8 to step a10, step a12, step a14 to step a15 in FIG. The microprocessor 24 of the control device 12 that has detected this reads out the latest values of various setting information including the crane operating range restricted area from the nonvolatile memory 22 functioning as the data storage means C, and the processing of step a7 All the mobile terminals 18 whose identification information is stored in the non-volatile memory 22 as destinations of information are sent to the destination, and the setting information together with the identification information of the control device 12 via the adapter 27a constituting the transmission / reception unit G. Then, it transmits again by multicast (step a11).
The setting information and the identification information are stored in the microprocessor of the portable terminal 18 that repeatedly executes the processing of Step b2 to Step b3, Step b18, Step b20 to Step b23, Step b33, Step b42, Step b45 to Step 46, and Step b48. The microprocessor 35 that has detected this in step b18 and searches for the address of the monitoring target storage table T2 storing the identification information corresponding to the received identification information, and the address corresponding to the received identification information The setting information is updated and stored in the data storage area of the monitoring target storage table T2 (step b19).

Unless a special operation is applied to the portable terminal 18, the microprocessor 35 of the portable terminal 18 performs steps b2 to b3, step b18, step b20 to step b23, step b33, step b42, step b45 to step 46, and step b48. The processing is repeatedly executed, and the microprocessor 24 of the control apparatus 12 repeatedly executes the processing of step a2 to step a4, step a8 to step a10, step a12, and step a14 to step a15. The change in the load suspension state information in the mobile crane 1 is immediately reflected in the contents of the data storage area of the monitoring target storage table T2 on the portable terminal 18 side that temporarily stores the load suspension state information of the crane vehicle 1 (step a9, step b20). ~ See step b21 In addition, when the work manager or the like operates the portable terminal 18 and transmits a transmission request signal for requesting transmission of setting information, the control device 12 immediately responds to the portable terminal 18 with the latest setting information. The changed contents are immediately reflected in the contents of the data storage area of the monitoring target storage table T2 on the mobile terminal 18 side that temporarily stores the setting information of the crane 1 (step b48 to step b49, step a10). To steps a11 and b18 to b19).
Since the display switching of the load suspension state information and setting information in the portable terminal 18 is repeatedly executed at predetermined intervals (see step b45), the work manager or the like can perform the load suspension state information on the crane vehicle 1 to be monitored. Can be grasped substantially in real time, and the latest setting information check operation in the control device 12 of the crane 1 can be performed at an appropriate timing as required.
Further, since the selection item switching operation is also detected repeatedly at predetermined intervals (see step b42), the work manager or the like performs the selection item switching operation to be displayed at an arbitrary timing as necessary. be able to.

The value “1” is set in the register R when the processing in the single display mode described above, that is, when the determination result in step b24 is true and the current value of the index C is found to be “1”. What is required for processing performed under the condition that the value “1” is forcibly set in the mode selection flag F2 is a display for selecting only one crane vehicle to be monitored among a plurality of crane vehicles 1. It is the monitoring information display control means L which displays only the information of the crane 1 corresponding to the identification information selected by the object selection means I and the display object selection means I on the display 28 of the portable terminal 18, and is used for area division. The functions of the display area specifying means M and the monitoring information batch display control means N for displaying information in the divided areas are not necessary.
This situation corresponds to the situation where the display object selection means I and the monitoring information display control means L are selected by the switching means shown in the functional block diagram of FIG.
In this situation, the operation manager or the like operates the touch panel in order to select only one crane vehicle to be monitored from among the plurality of crane vehicles 1 by operating the display target selecting means I again. Thus, it is necessary to re-input the request for starting the object selection process to the portable terminal 18 (see step b3). The contents of the object selection process are as already described.

  On the other hand, if the determination result of step b24 described above (see paragraph 0090) is false and it is clear that the current value of the index C is greater than “1”, the target is monitored. Since it means that two or more crane vehicles 1 are selected, it is possible to execute batch display mode processing for simultaneously displaying information on a plurality of crane vehicles 1 according to the initial value “0” of the mode selection flag F2. It is.

  In this case, the microprocessor 35 of the portable terminal 18 first determines whether a display mode switching operation is performed by a work manager or the like who operates the touch panel 29 functioning as the man-machine interface Q (step). b25).

  If the display mode switching operation has not been performed, the microprocessor 35 of the portable terminal 18 functioning as the monitoring information batch display control means N uses the addresses 1 to 1 in the monitoring target storage table T2 as shown in FIG. All the sets of handle name H, display item information K, display area information P, setting information D and load suspension state information D ′ currently stored at address C are read (step b36), and then the man-machine interface It is determined whether or not a display item switching operation is performed by a work manager who operates the touch panel 29 functioning as Q (step b37).

If the display item switching operation is not performed, the microprocessor 35 of the portable terminal 18 functioning as the monitoring information batch display control means N displays the display set in advance by the display area specifying means M in the process of step b16 described above. According to the area information P _{1 to} Pc, that is, the information specifying the position of the display area for each of the C cranes 1, the screen of the mobile terminal 18 is shown in, for example, FIGS. 11 (b) to 11 (d). Are divided into C display areas, and handle names H _{1 to} Hc corresponding to the display areas P _{1 to} Pc at the ends of the display areas P ₁ to Pc, for example, No. 1, No. 2, No. 3, .. etc. are displayed, display item information K _{1 to} Kc corresponding to each handle name H ₁ to Hc is referred, various setting information D _{1 to} Dc and various load suspension state information D ₁ ′ to Dc 'Out of each Display item information K ₁ item of information specified in ～Kc, for example, only the "working range limited region" of the configuration information, or a combination such as "other setting information" and the "working range restricted area", or , Only “boom hoisting angle” in the load suspension state information, or two types of items such as “boom hoisting angle” and “turning angle”, a combination of three items... The information such as the combination of some items of the item and some items of the loading state information is updated and displayed in the display areas P _{1 to} Pc of the display screen in the collective display mode on the display 28 (step b41). .
In addition, the division | segmentation condition in case two crane vehicles 1 selected as monitoring object respond | corresponds to FIG.11 (b), and the division | segmentation situation in case three crane vehicles 1 selected as monitoring object is a figure. 11 (c) corresponds to FIG. 11 (d) when the number of crane vehicles 1 selected as the monitoring targets is four.

Further, when it is confirmed that the display item switching operation has been performed in the determination process of step b37 after the next cycle, that is, it is confirmed that the display item switching operation has been performed during the execution of the batch display mode. In this case, the microprocessor 35 of the portable terminal 18 functioning as the display item selection means P handles the handle names H _{1 to} Hc displayed in the display areas P _{1 to} Pc of the display screen in the collective display mode on the display 28. The display item information K corresponding to the handle name H is considered to be changed (step b38).
Then, the microprocessor 35 of the portable terminal 18 functioning as the display item selection means P executes the processing of step b39 to step b40 in the same manner as the processing of step b9 to step b10 described above, and is newly selected as a display item. Type of information, for example, only “operation range restricted area” in the setting information, or a combination of “operation range restricted area” and “other setting information”, or “boom ups and downs” in the load state information Only “angle”, or a combination of two types of items such as “boom hoisting angle” and “turning angle”, three types of items... A combination of some items is stored in the monitoring target storage table T2 specified by the handle name selected in the process of step b38. In correspondence with the address, and stores and updates the monitoring target storage table T2 as a new display item information.
In this case, new display item information in the monitoring target storage table T2 after the change is reflected in the information displayed in the update display process in step b41.

Unless a special operation is applied to the mobile terminal 18, the microprocessor 35 of the mobile terminal 18 repeatedly executes the processing of step b2 to step b3, step b18, step b20 to step b25, step b36 to step b37, step b41, And since the microprocessor 24 of the control device 12 repeatedly executes the processing of step a2 to step a4, step a8 to step a10, step a12, step a14 to step a15, the plurality of crane vehicles 1 to be monitored. Change in the load suspension state information in step 1 is immediately reflected in the contents of the data storage area of the monitoring target storage table T2 on the portable terminal 18 side that temporarily stores the load suspension state information of each crane vehicle 1 (step a9, step b20 to step b). b21).
Since the display switching of the load suspension state information and setting information in the portable terminal 18 is repeatedly executed at predetermined intervals (see step b41), the work manager or the like can perform the load suspension in the plurality of crane vehicles 1 to be monitored. Changes in state information can be grasped substantially in real time.
Moreover, since the detection of the selection item switching operation is also repeatedly executed at predetermined intervals (see step b37), the work manager or the like performs the selection item switching operation to be displayed for each crane 1 as necessary. It can be implemented at any timing.

  As described above, in the batch display mode processing, information on the plurality of crane vehicles 1 is displayed collectively on the screen of the display 28 in the portable terminal 18. The display area defined in the above is continuously displayed together with the handle name of the crane vehicle 1, so that the work manager or the like who has the portable terminal 18 may perform work using a plurality of crane vehicles 1 together. Even if it exists, the operation state of all the crane vehicles 1 currently monitored and the setting information of each crane vehicle 1 can be accurately grasped by one mobile terminal 18 without causing confusion.

As described above, it is found that the current value of the index C is larger than “1”, and is required when executing the batch display mode processing according to the current value “0” of the mode selection flag F2. The display area specifying means M for dividing the screen of the display 28 into a plurality of display areas so as to correspond to the identification information for specifying the crane 1 and the display of the received information corresponding to each identification information. This is monitoring information batch display control means N that updates and displays the area.
This situation corresponds to the situation where the display area specifying means M and the monitoring information batch display control means N are selected by the switching means shown in the functional block diagram of FIG.

  When the display mode switching operation is performed by a work manager or the like who operates the touch panel 29 functioning as the man-machine interface Q while the batch display mode processing is performed in this manner, It is detected by the microprocessor 35 of the portable terminal 18 in the determination process of b25.

Next, the microprocessor 35 of the portable terminal 18 performs work management in which any of the handle names H _{1 to} Hc displayed in the display areas P _{1 to} Pc of the display screen in the collective display mode on the display 28 operates the touch panel 29. Wait until it is selected by the person, etc., and when the handle name selection operation is detected, only the information on the crane vehicle 1 corresponding to the handle name H is specified as the information display target in the single display mode, and The microprocessor 35 of the portable terminal 18 functioning as the operation target selection means S identifies this crane vehicle 1 as the crane vehicle 1 for which the command is to be transmitted (step b26).

  Then, the microprocessor 35 of the portable terminal 18 functioning as the operation target selection unit S refers to the monitoring target storage table T2, obtains the value of the address corresponding to the handle name selected by the work manager or the like, and temporarily stores the value. Set to the register R for storage (step b27).

Next, the microprocessor 35 of the portable terminal 18 switches the screen display of the display 28 to the display screen of the single display mode as shown in FIG. 11A, and displays the display area P ₁ that occupies most of the display screen and the remaining display. The area P ₀ is divided into two (step b28) and stored in the address R (the address value corresponding to the handle name of the crane 1 selected as the information display target and the command transmission target) of the monitoring target storage table T2. display Referring to item information are, displays only the information items that are stored as display items of the various types of setting information and various suspended load state information of the display area P ₁ (step b29), the display region P ₀ Display the command input screen (step b30), and set the mode selection flag F2 to the value “1” indicating that the single display mode is being selected. (Step b31), the process returns to step b2.

  Regarding the processing in the single display mode in this case, only one crane vehicle 1 to be monitored is registered in the monitoring target storage table T2 except that the value of the register R can be arbitrarily selected in the range of 1 to C. This is exactly the same as the processing in the case (processing when the value of the register R is limited to 1).

Unless a special operation is applied to the mobile terminal 18, the microprocessor 35 of the mobile terminal 18 performs steps b2 to b3, step b18, steps b20 to b23, step b33, step b42, steps b45 to step 46, steps. The processing of b48 is repeatedly executed, and the microprocessor 24 of the control device 12 repeatedly executes the processing of step a2 to step a4, step a8 to step a10, step a12, and step a14 to step a15. The change of the load suspension state information in one crane vehicle 1 that is the target and the operation target is the content of the data storage area of the monitoring target storage table T2 on the portable terminal 18 side that temporarily stores the load suspension state information of the crane vehicle 1. (Step a9, When the work manager or the like operates the portable terminal 18 to transmit a transmission request signal for requesting transmission of setting information, the control device 12 immediately responds to the latest information. The setting information is transmitted to the portable terminal 18, and the contents of the change are immediately reflected in the contents of the data storage area of the monitoring target storage table T2 on the portable terminal 18 side which temporarily stores the setting information of the crane 1 (step b48 to step b). b49, step a10 to step a11, step b18 to step b19).
Since the display switching of the load suspension state information and the setting information on the portable terminal 18 is repeatedly executed at predetermined intervals (see step b45), the work manager or the like can load the crane vehicle 1 to be monitored and operated. The change of the suspension state information can be grasped substantially in real time, and the setting information confirmation work in the control device 12 of the crane 1 can be performed at an appropriate timing as necessary.
Further, since the selection item switching operation is also detected repeatedly at predetermined intervals (see step b42), the work manager or the like performs the selection item switching operation to be displayed at an arbitrary timing as necessary. be able to.

  Moreover, since the command transmission control means T functions for one crane vehicle 1 selected by the operation object selection means S (see step b47), the work manager or the like having the portable terminal 18 selects the operation object. By inputting the handle name to the microprocessor 35 functioning as the means S (see Step b25 to Step b27), the desired crane vehicle 1 is stored as a monitoring target in the monitoring target storage table T2 and selected from the plurality of crane vehicles 1. Can be freely selected, and several actuators of the selected crane 1 such as a hoisting hydraulic cylinder 9, a telescopic hydraulic cylinder, a winch hydraulic motor, a turning hydraulic motor, etc. It can be operated freely from the ground.

  When the display manager is operated to operate the touch panel 29 functioning as the man-machine interface Q and the display mode switching operation is performed while the processing of the single display mode is performed in this way, this operation is performed. Is detected by the microprocessor 35 of the portable terminal 18 in the determination process of step b33, and the microprocessor 35 that has detected this determines whether or not the current value of the index C is “1” (step b34).

  In this case, since two or more crane vehicles 1 to be monitored are selected and C> 1 and the determination result in step b34 is true, the microprocessor 35 of the portable terminal 18 sets the mode selection flag F2 at once. A value “0” indicating that the display mode is being selected is set (step b35).

  Even when the single display mode is selected, the processing of Step b2 to Step b3, Step b18, Step b20 to Step b23, Step b33, Step b42, Step b45 to Step 46, and Step b48 by the microprocessor 35 of the portable terminal 18 is performed. Since it is repeatedly executed and the microprocessor 24 of the control device 12 also repeatedly executes the processing of step a2 to step a4, step a8 to step a10, step a12, and step a14 to step a15, the monitoring target memory is stored as the monitoring target. The change in the load suspension state information in all crane vehicles 1 whose identification information is registered in the table T2 is reflected in the contents of the data storage area of the monitoring target storage table T2 without delay.

Therefore, the microprocessor 24 of the control device 12 uses the handle name H, the display item information K, the display area information P, the setting information D, and the load suspension state currently stored in the addresses 1 to C of the monitoring target storage table T2. All the sets of information D ′ can be read out by the process of step b36, and the process can be immediately shifted to the batch display mode process.
The processing of the microprocessor 35 in the collective display mode is as already described.

In this embodiment, the mobile terminal 18 is configured using a smartphone or a mobile phone, and a plurality of cranes are provided for the purpose of preventing operation because the surface area of the display 28 and the touch panel 29 for command input is small. When only one crane vehicle 1 is selected as a monitoring target from the vehicles 1 by the display target selection means I, that is, as a result of the value of the index C being “1”, the value “1” is set in the mode selection flag F2. "" Is forcibly set, and one crane vehicle 1 is further selected as the operation target by the operation target selection means S from the plurality of crane vehicles 1 stored as the monitoring targets in the monitoring target storage table T2. In other words, in other words, in a situation where the value of the index C is larger than “1”, the value of the register R is specified as any one of 1 to C and the mode selection flag is set. If the grayed F2 value "1" is set, in short, only when the display mode of the single display mode is selected and the area of the display screen of the display region P ₁ and the command input screen P ₀ of the information is secured In the case where the operation of the command transmission control means T is permitted, a terminal having a display or touch panel with a sufficient area such as a tablet terminal, a laptop personal computer, or a notebook personal computer is used as the portable terminal 18. Then, in the collective display mode, either the handle name or the display area is selected by the operation object selection means S while the information related to the plurality of crane vehicles 1 is displayed in the display areas P _{1 to} Pc. By identifying the crane vehicle 1 as the operation target and maintaining the display state of information related to other crane vehicles, by specifying the handle name and display area It may be caused to operate the command transmission control unit T-option has been crane truck 1 only for operations.

Here, FIG. 12 shows one example of use when the mobile terminal 18 monitors the setting information and the load state information of the crane vehicle 1.
Reference numerals 1 a and 1 b are crane trucks equivalent to the crane truck 1, and reference numerals 18 a and 18 b are portable terminals equivalent to the portable terminal 18.
Reference numeral 18c denotes a portable terminal composed of a notebook personal computer or the like, and an application program similar to the above-described application program (see FIGS. 7 to 9) is installed on a hard disk or the like, and an adapter corresponding to Wi-Fi communication is installed. I have.
Regarding the portable terminal 18c composed of a notebook personal computer or the like, the area division of the display 28c is horizontally divided, but this is simply because such a division method is applied because the display 28c of the notebook personal computer or the like is horizontally long. However, the display screen of the display 28c is divided into C display areas based on the value of the index C, which is exactly the same as the case of the mobile terminal 18 described above.

  In FIG. 12, in the situation where the hooks 11a, 11b of the crane vehicles 1a, 1b are hung on both ends of the suspended load 41 and the suspension work is carried out, setting information and loads related to the crane vehicle 1a using the portable terminal 18a. It shows a case where the suspension state information is monitored, and the setting information and the load state information related to the crane vehicles 1a and 1b are simultaneously monitored using the portable terminal 18b and the portable terminal 18c.

In order to realize such a monitoring environment, first, the control devices 12 and 12 of the crane trucks 1a and 1b are activated, and three work managers or the like having the portable terminals 18a, 18b, and 18c 18a, 18b, and 18c are operated in an arbitrary order to start object selection processing (see step b3 to step b12 in FIG. 7) by each microprocessor 35. In the object selection processing of the portable terminal 18a, the handle of the crane vehicle 1a is started. Only the name is selected and the handle name is stored as a monitoring target in the monitoring target storage table T2 of the mobile terminal 18a. In the target selection process of the mobile terminal 18b, both the handle names of the crane truck 1a and the crane truck 1b are selected. In the monitoring target storage table T2 of the mobile terminal 18b, those handle names are stored as monitoring targets, and in the target selection process of the mobile terminal 18c, Handle name of the axis crane 1a and crane vehicles 1b together by selecting the monitoring target storage table T2 of the mobile terminal 1c and stores it these handle name as the monitor.
As a result, in the process of step b13 in FIG. 7 in the portable terminal 18a, the identification information of the portable terminal 18a is transmitted only to the control device 12 installed in the crane vehicle 1a, and installed in the crane vehicle 1a according to this operation. In the process of step a7 in FIG. 6 in the control device 12, the identification information of the portable terminal 18a is stored in the nonvolatile memory 22 of the control device 12 as the identification information of the portable terminal that is the information transmission target.
Moreover, in the process of step b13 in the portable terminal 18b, the identification information of the portable terminal 18b is transmitted to the control device 12 installed in the crane vehicle 1a and the control device 12 installed in the crane vehicle 1b. In the process of step a7 in the control device 12 installed in the car 1a, the identification information of the portable terminal 18b is stored in the nonvolatile memory 22 of the control device 12 as the identification information of the portable terminal to which information is to be transmitted. In the process of step a7 in the control device 12 installed in the car 1b, the identification information of the portable terminal 18b is stored in the nonvolatile memory 22 of the control device 12 as the identification information of the portable terminal that is the information transmission target.
Similarly, in the process of step b13 in the portable terminal 18c, the identification information of the portable terminal 18c is transmitted to the control device 12 installed in the crane vehicle 1a and the control device 12 installed in the crane vehicle 1b, and according to this operation, In the process of step a7 in the control device 12 installed in the crane vehicle 1a, the identification information of the portable terminal 18c is stored in the nonvolatile memory 22 of the control device 12 as the identification information of the portable terminal to which information is to be transmitted. In the process of step a7 in the control device 12 installed in the crane 1b, the identification information of the portable terminal 18c is stored in the nonvolatile memory 22 of the control device 12 as the identification information of the portable terminal that is the information transmission target. Become.
As a result, the mobile terminal 1a, 18b, 18c is selected by the control device 12 of the crane 1a as the information transmission target based on the identification information stored in the nonvolatile memory 22. (See the arrows 1, 2, and 3 in FIG. 12), the mobile terminal that the control device 12 of the crane 1b selects as the information transmission target based on the identification information stored in the nonvolatile memory 22 thereof The two portable terminals 18b and 18c are obtained (see arrows 4 and 5 in FIG. 12).
On the other hand, only the control device 12 of the crane 1a selects the mobile terminal 18a as the information transmission target with reference to the identification information stored in the monitoring target storage table T2 (see 6 in FIG. 12). It is the two control devices 12 and 12 of the crane vehicles 1a and 1b that the portable terminal 18b selects as information transmission targets with reference to the identification information stored in the monitoring target storage table T2) (Refer to the arrows 7 and 8 in FIG. 12) The mobile terminal 18c refers to the identification information stored in the monitoring target storage table T2 and selects the information transmission target of the cranes 1a and 1b. Two control devices 12 and 12 (see arrows 9 and 10 in FIG. 12).
Accordingly, as long as the object selection process (see step b3 to step b12 in FIG. 7) in the portable terminal 18 is appropriately performed, the work manager or the like can perform the crane vehicle 1 to be monitored regardless of the number of crane vehicles 1. Only a necessary number of them can be selected, and setting information and load state information of those crane vehicles 1 can be appropriately monitored. The correspondence relationship between the crane vehicle 1 and the portable terminal 18 may be one-to-one, many-to-one, or one-to-many.

In the situation of FIG. 12, since the mobile terminal 18a selects only the crane vehicle 1a as the monitoring target and the value of the index C is “1”, the value of the mode selection flag F2 is “1”. As shown in FIG. 11 (a), it is fixed (see step b17, step b23 to step b24, step b31, step b23, step b33 to step b34) and can be used by a work manager having the portable terminal 18a. Only the display screen in the single display mode.
In the situation where the display screen of the single display mode is displayed, a work manager operating the touch panel 29 functioning as a man-machine interface Q for inputting a command is shown in FIG. by performing a reference to a command input operation on the touch panel 29 a command input screen in the display region P ₀ in the above screen, in which the controllable device 12 having the identification information stored in the address R of the monitoring target storage table T2 Several actuators provided in the crane vehicle 1 such as the hoisting hydraulic cylinder 9, the telescopic hydraulic cylinder, the winch hydraulic motor, and the turning hydraulic motor can be freely operated from a remote place.

In addition, since the mobile terminals 18b and 18c have selected the crane vehicles 1a and 1b as the monitoring targets and the value of the index C is “2”, the value of the mode selection flag F2 is collectively set by default. Although the value indicating the display mode is set to “0” (see step b17), switching from the collective display mode to the single display mode (see steps b25 and b26 to b31) is also performed from the single display mode to the collective display mode. (See step b33, step b34 to step b41) is also permitted.
The processing in the single display mode that is forcibly executed when there is only one crane vehicle 1 to be monitored is one crane vehicle 1 among the plurality of crane vehicles 1 whose information is displayed in the collective display mode. However, in the former case, the value that can be taken by the register R for temporary storage is “1”. Only, that is, only the value indicating the identification information of the only crane vehicle 1 stored in the monitoring target storage table T2, and in the latter case, the possible value of the register R is any value of 1 to C, that is, The value indicates identification information for specifying one crane vehicle 1 among the plurality of crane vehicles 1 stored in the monitoring target storage table T2.

Among Ichii's VNC packages, Multiple Virtual Network Computing (hereinafter referred to as “Multi VNC”) has the ability to view and operate multiple desktops on a network in a LAN environment with a single computer. Since it is necessary to browse the screen, it has a function of dividing the display area of the computer monitor (current division number is 1 × 1 to 4 × 4).
Therefore, if the control device 12 of the work machine 1 is regarded as a client and the MultiVNC client software is installed, and the mobile terminal 18 having a computer function is regarded as a server and the MultiVNC server software is installed, the mobile terminal 18 is displayed. The desktop screen of the control device 12 to be displayed on the means K can be selectively selected to switch the display, and the desktop screens of the plurality of control devices 12 can be divided into split screens on the display means K of the portable terminal 18. It is also possible to display at the same time and select and display a desired desktop screen of the control device 12 from among them.
In addition, the mobile terminal 18 in which the MultiVNC server software is installed selects the desktop screen of the specific control device 12 and then selects “screen operation” to specify the work target, thereby specifying the desktop of the specific control device 12. The screen can be operated on the display means K of the portable terminal 18.
On the other hand, the control device 12 of the crane vehicle 1 has, as its basic configuration, information (loading state information) detected by the sensor group A installed in each part of the crane vehicle 1 and the man-machine interface B. The command (input information) input by the operator is stored in the data storage means C, and at least a part of the information is output to the display means D for visual display, and the command input by the operator via the man-machine interface B Is provided with the function of the main control unit F that controls the driving of the actuator group E included in the crane vehicle 1 as before, and the display of load suspension state information and setting information is man-machine interface B using a GUI.

After setting information such as the operating range restriction area is displayed, the information is transferred from each control device 12 to the mobile terminal 18, and the display state of the display means K of the mobile terminal 18 is set as a divided screen. It is also possible to display the load suspension state information, the operating range restriction region, and the like displayed on the display means D in each divided screen.
This function is for displaying and updating each information in the function of the display area specifying means M that makes the crane vehicle 1 and the divided display area correspond one-to-one or the display area corresponding to each crane vehicle 1. This corresponds to the function of the monitoring information batch display control means N.
Similarly to the above, when each control device 12 having the MultiVNC client function transmits screen information to the mobile terminal 18 having the MultiVNC server function, each control device 12 divides the screen converted into pixel data into small rectangles. Since the information is transmitted to the portable terminal 18, the microprocessor 24 and the MultiVNC client software of each control device 12 function as the information transmission control means H (refer to Appendix 10 above). reference).

Further, the command input operation performed by the operator via the man-machine interface B in order to control the driving of the actuator group E included in the crane vehicle 1 is performed by using the GUI displayed on the desktop screen of the display means D of the control device 12. The portable terminal 18 having a man-machine interface Q equivalent to the man-machine interface B of the control device 12 selects one control device 12 having a MultiVNC client function. This desktop screen is displayed and operated on the display means K of the portable terminal 18, and the desktop screen of the display means D in the plurality of control devices 12 having the MultiVNC client function is displayed on the display means K of the portable terminal 18. The desktop screen of the control device 12 as a work control after being displayed in a split screen Since it is possible to make a selection, the desktop device for command input in the control device 12 is displayed on the display means K of the portable terminal 18 by using these functions, whereby the control device for the crane vehicle 1 to be operated is controlled. 12 can be selected with the portable terminal 18, and the actuator group E with which the crane vehicle 1 is provided can be operated freely.
This function accepts a command input by a work manager or the like via the function of the operation object selection means S for specifying the crane 1 that transmits the command or the man-machine interface Q of the portable terminal 18, and the operation object selection means. This corresponds to the command transmission control means T that transmits to the transmission / reception unit G included in the control device 12 of the crane 1 selected by S (see Appendix 11).

  In addition, in the control device 12 having a GUI, when selecting setting information and load state information to be displayed on the display means D, a display screen containing related information is displayed on the desktop screen in tab form. In general, the display items are selected by selecting the item, and these desktop screens are also selected for one control device 12 or as a monitoring target by operating the portable terminal 18 having the MultiVNC server function. Since all the control devices 12 can be collectively displayed on the display means K of the portable terminal 18 and tabs can be freely selected, a display for selecting a combination of setting information and load state information The mobile terminal 18 can also function as the item selection means P.
