Description

  The present invention relates to an elevator system installed in a building such as a building, and in particular, transmission of an elevator for exchanging information between a main control device that controls movement of the elevator car and a child device such as a call registration device. About the system.

  In an elevator system installed in a building such as a building, as shown in FIG. 18, the car 1 is moved up and down via a rope 3 in a machine room above the hoistway 2 in which the elevator car 1 moves up and down. A hoisting machine 4 including an electric motor to be driven, a drive unit 5 for driving the hoisting machine 4, and a main controller 6 are provided.

  Further, for example, in the case of an eight-story building, each hall call registered in the hall call registration device 7 provided in the elevator hall on each floor from the first floor (1F) to the eighth floor (8F) is transmitted via the transmission path 8. To the main controller 6. The car call registered in the car call registration device 9 provided in the car 1 is input to the main control device 6 via the transmission path 10. The main controller 6 and the drive unit 5 are accommodated in the control panel 12. Power is supplied to the main controller 6 and the drive unit 5 from an external power source 11.

  As shown in FIG. 19 (a), each hall call registration device 7 includes up and down direction buttons 7a and 7b, the current moving direction of the elevator car 1, and the current position (floor). A display 7c for displaying is incorporated. In addition, as shown in FIG. 19B, the car call registration device 9 includes eight destination buttons 9a for designating a destination floor, nine button lamps 9b incorporated in each destination button 9a, and a self A display 9c for displaying the moving direction of the car 1 and the current position (floor) is incorporated.

  When the hall call or car call is input via the transmission lines 8 and 10, the main controller 6 detects the current position (floor) of the car 1 and designates the car 1 as the hall call or car call. A command to move to the destination floor is sent to the drive unit 5. The drive unit 5 drives the electric motor of the hoisting machine 4 to move the car 1 to the destination floor.

  In addition, an elevator transmission system that performs transmission / reception of information between the main control device 6 and each hall call registration device 7 and information transmission / reception between the main control device 6 and the car call registration device 9 in a cyclic transmission system is patented. It is presented in Document 1.

  That is, each of the hall call registration devices 7 of 1F to 8F sends a “hall call” designating the own floor registered by the operation of each direction button 7a, 7b to the main control device 6 and is displayed from the main control device 6. Information on the moving direction and car position of the elevator displayed on the unit 7c is input. The car call registration device 9 sends a “car call” designating the destination floor registered with the destination button 9a to the main control device 6, and the moving direction of the elevator displayed on the display 9c from the main control device 6. The car position information and the information for lighting the button lamp 9b of the floor registered by “car call” are input.

In the cyclic transmission system, as shown in FIG. 20, the main controller 6 transmits / receives information (button operation, transmission / reception) to / from the hall call registration devices 7 from the first floor (1F) to the eighth floor (8F). Elevator position) and individual information AD ₁ , AD ₂ ,..., AD ₁₉ are set for each information (button operation, elevator position, lighting button, etc.) transmitted to and received from the car call registration device 9.

Then, as shown in FIG. 21A, the data are cyclically output to the transmission lines 8 and 10 at a constant time interval T _S such as 200 μs. The main control device 6 follows the addresses AD ₂ , AD ₄ ,..., AD ₁₉ for transmitting information (output data) to the child devices of the hall call registration device 7 and the car call registration device 9. The information to be transmitted (elevator position D ₂ ), (elevator position D ₄ ),..., (Lighting button D ₁₉ ) is output to transmission lines 8 and 10. It is to be noted that addresses AD ₁ , AD ₃ ,... For receiving information (input data) such as hall calls and car calls (button operation) from child devices of the hall call registration device 7 and the car call registration device 9 are received. Address.

  When each of the child call registration devices 7 and the car call registration device 9 connected to the transmission lines 8 and 10 outputs the reception address set in the own device of the transmission lines 8 and 10, Information to be transmitted to the control device 6 (input data, button operation) is output to the transmission lines 8 and 10. Further, each slave device receives the transmission address set in its own device on the transmission lines 8 and 10 and receives the information following this address as information (output data) addressed to itself, for example, on the display. indicate.

For example, when the address AD ₁ is output from the main controller 6 to the transmission line 8, hall call information (data D ₁₎ indicated by the presence / absence of operation of the direction buttons 7 a and 7 b from the hall call registration apparatus 7 on the first floor. ) Is output to the transmission line 8, and the main controller 6 takes in the information (data D ₁ ) as information (data D ₁ ) indicating the presence / absence of a landing call input from the landing call registration device 7 on the first floor. Perform the process.

Further, when the address AD ₂ and subsequent information (data D ₂ ) are output from the main controller 6 to the transmission line 8, the hall call registration device 7 on the first floor in which the address AD ₂ is set, (Data D ₂ ) is taken in and displayed as the current position (floor) of the elevator car 1 on the display 7c.

In such an elevator transmission system, for example, when the second floor hall call registration device 7 is out of order or the elevator is not stopped on the second floor, the operation of the second floor hall call registration device 7 is stopped. If it is, the second-floor landing is provided even if the reception address AD ₃ set in the second-floor landing call registration device 7 is output to the transmission route 8, as shown in FIG. Information (data D ₃ ) is not output from the call registration device 7. In this case, for example, the next address AD ₄ is output when an allowable time T _{E of} 300 μs elapses from the output of the receiving address AD ₃ .

Thus, when each child device is in a normal state, each child device and the main control device 6 cyclically transmit information at a constant cycle T (= 3, 8 ms) such as 3, 8 ms.
Japanese Patent Laid-Open No. 2004-120043

  However, the elevator transmission system as described above still has the following problems to be improved.

  In the elevator system shown in FIG. 22, a large number of setting data including adjustment data for smoothly moving the elevator car 1 to the destination floor is stored in the main controller 6. The maintenance staff temporarily installs the information terminal 13 on the transmission line 8 for confirming, adjusting, and changing these setting data at the time of periodic maintenance inspection of the elevator system.

  The maintenance staff operates the information terminal 13 to check, adjust, and change setting data in the main control device 6.

In this case, as shown in FIG. 23, the information terminal 13 temporarily attached to the transmission line 8 is also similar to each hall call registration device 7 and car call registration device 9 connected to the transmission lines 8 and 10. A plurality of addresses AD ₂₀ , AD ₂₁ , AD ₂₂ , AD ₂₃ are set. Therefore, the information terminal 13 also exchanges information with the control device 6 under the same conditions as the hall call registration device 7 and the car call registration device 9.

However, since a large amount of information is transmitted and received between the information terminal 13 and the main control device 6 due to the function of the information terminal 13, as shown in FIG. 23, the hall call registration device 7 and the car call registration device 9 Addresses AD _{20 to} AD _{23 that} are more than twice as large as the above are set. Moreover, among the four addresses, the three addresses AD _{20 to} AD ₂₂ from the head are reception addresses for receiving each piece of information (data D _{20 to} D ₂₂ ) from the information terminal 13.

Therefore, in the state where the maintenance and inspection work for the elevator system described above is completed and the information terminal 13 is removed from the transmission line 8, the main controller 6 sends the addresses AD _{20 to} AD ₂₂ of the information terminal 13 to the transmission line 8. Even if the information is output, each information (data D _{20 to} D ₂₂ ) is not output from the information terminal 13, so that the main control device 6 normally uses the second and subsequent addresses AD ₂₁ , AD ₂₂ , AD ₂₃ . Are output at intervals of an allowable time T _E (= 300 μs) that is longer than the time interval T _S (= 200 μs) by 100 μs.

Actually removing and outputting a large number of addresses set in the information terminal 13 that is not attached to the transmission line at an interval of an allowable time T _E longer than the normal time interval T _S results in this transmission. The period T of information transmission between each of the hall call registration devices 7 and the car call registration devices 9 connected to the roads 8 and 10 and the main control device 6 becomes longer, and the main control device 6 is connected to each of the hall call registration devices 7. There is a concern that information collection for the car call registration device 9 may be delayed.

  Note that the above-described problem also occurs when, for example, the elevator is not stopped on a specific floor and the operation of the hall call registration device 7 on the specific floor is stopped. This means that it takes a long time for the elevator user to operate the elevator call registration device 7 and the car call registration device 9 until the elevator car actually starts moving, resulting in a decrease in responsiveness. I feel I did it.

  The present invention has been made in view of such circumstances, and even when each child device including the information terminal is removed from the transmission line or when the operation is stopped, the remaining child devices and the main device are not included. It is an object of the present invention to provide an elevator transmission system that can prevent a period of information transmission with a control apparatus from becoming significantly long and can improve elevator responsiveness.

  The present invention includes a plurality of slave devices including a call registration device that is provided in an elevator hall and elevator car on each floor of a building and registers each call input by operation, and is connected to each slave device via a transmission line. This is an elevator transmission system that transmits and receives various information including calls to and from a main control device that controls the movement of a car for each registered call.

  In this elevator transmission system, a plurality of addresses are set for each slave device, the main control device cyclically outputs each address to the transmission path, and each slave device is self-addressed to the transmission path. When the address is output, the information to be transmitted is output to the transmission line, and when the main control unit cannot receive the information even after the allowable time has elapsed from the address output, the output of the remaining address to the child device is omitted. Outputs the address for the next child device.

  In the elevator transmission system configured as described above, even if the slave device is removed from the transmission path or the operation stop state is generated due to some cause, the plurality of addresses set for the slave device are not detected. Since only the first address is sent to the transmission line and the remaining addresses are not output, it is possible to prevent the period of information transmission between the remaining child devices and the main control device from becoming significantly long.

  Further, in an elevator transmission system according to another invention, an information terminal which is provided detachably with respect to the transmission line and exchanges information with the main control device while being attached to the transmission line is provided with a plurality of child terminals. Used as a device. A plurality of addresses are set for each child device including the information terminal, the main control device cyclically outputs each address to the transmission line, and each child device has its own address on the transmission line. When it is output, it outputs the information to be transmitted to the transmission line, and when the main control unit cannot receive the information even after an allowable time has elapsed since outputting the address of the information terminal, it outputs the remaining address to the information terminal. If omitted, the address for the next child device is output.

  In the elevator transmission system configured as described above, in a state where the information terminal is removed from the transmission path, the main control device is the first address among the plurality of addresses set for the information terminal. Since only the remaining addresses are sent to the transmission line and the remaining addresses are not output, it is possible to prevent the period of information transmission between the remaining child devices and the main control device from becoming significantly longer, as in the above-described invention. .

  Further, in an elevator transmission system according to another invention, an information terminal which is provided detachably with respect to the transmission line and exchanges information with the main control device while being attached to the transmission line is provided with a plurality of child terminals. Used as a device. Then, an address is set for each child device including the information terminal, the main control device cyclically outputs each address to the transmission line, and each child device outputs its own address to the transmission line. The information to be transmitted is output to the transmission line, and when the main control apparatus receives the information from the information terminal, an additional address is set for the information terminal and the address is output to the transmission line.

  In the elevator transmission system configured as described above, for example, since only one address is initially set in the information terminal, even if the information terminal is removed from the transmission path. Since only one permissible time for one address is added, it is possible to prevent the period of information transmission between the remaining child devices and the main control device from becoming significantly long. When the information terminal is attached to the transmission path, an additional address is automatically set for the information terminal, so that sufficient information exchange can be performed with the main control device as the information terminal.

  In an elevator transmission system according to another invention, at least a plurality of addresses including an information reception address and an information transmission address are set for each child device, and the main control device is connected to the transmission line. The information reception address and the information transmission address and information are cyclically output, and each child device outputs the information to be transmitted to the transmission path when its own information reception address is output to the transmission path. When an address for transmitting own information is output to the transmission line, information following this address is received as information addressed to itself, and the main control unit cannot receive information even if an allowable time elapses from output of the information receiving address. At this time, the output of the remaining address and information for the child device is omitted, and the information receiving address for the next child device is output.

  In the elevator transmission system configured as described above, when a slave device that is removed from the transmission path or is in an operation stop state is generated for some reason, the information transmission address set in the slave device and Since information to be transmitted to the child device is also blocked, useless addresses and useless information are prevented from being transmitted on the transmission path.

  In the present invention, even when each slave device that cyclically transmits information to and from the main control device is removed from the transmission path or when the operation is stopped, the remaining slave devices and the main control are controlled. It is possible to prevent the period of information transmission with the apparatus from becoming significantly long and improve the response of the elevator.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Entered. Further, a car call registration device 9 shown in FIG. 19B is provided in the car 1, and the car call registered by the car call registration device 9 is input to the main control device 6 a through the transmission path 10. .

  Further, the transmission line 8 is used for checking, adjusting, and changing the setting data stored in the main controller 6a with respect to the main controller 6a during periodic maintenance and inspection of the elevator system. The information terminal 13 is detachably attached to the transmission line 8.

  Information exchange between each child device such as each hall call registration device 7, car call registration device 9, and information terminal 13 and the main control device 6 a is performed by a cyclic transmission system via transmission paths 8 and 10.

  FIG. 3 is a block diagram showing a schematic configuration of the main control device 6a configured by, for example, a computer. In the main control device 6a, a call assignment unit 29, a car movement control unit 26, a setting data memory 27, an address / information correspondence table 27, and a transmission control for exchanging information with each child device by a cyclic transmission method. A data input / output control unit 28 is provided for relaying data reading and writing between the unit 14 and each of these units, memory, and tables.

  Further, in the transmission control unit 14 for exchanging information with each slave device by the cyclic transmission method, an address output order memory 16, an output address reading unit 17, an address output unit 18, a transmission / reception unit 19, a data output unit 20, a data extraction unit 25 is provided.

  Hereinafter, the specific configuration and specific operation of each part will be described in order.

In the address / information correspondence table 15 shown in FIG. 4, as described in FIGS. 20 and 23, eight hall call registration devices 7 from the first floor (1F) to the eighth floor (8F), car calls A plurality of addresses AD ₁ , AD ₂ ,..., AD ₂₃ set for each of a total of ten child devices of the registration device 9 and the information terminal 13 and information required by the corresponding address (button operation, command data, writing) Position (reading position), writing data), and information (elevator position, lighting button, display data) to be sent to each slave device after the corresponding address are set.

It should be noted that addresses (AD ₁ , AD ₃ ) for requesting (receiving) information 22 (data D ₁ , D ₃ , D ₅ ,..., D ₂₂ ) transmitted from each child device such as button operation to the main control device 6a. ,..., AD ₂₂ ) is defined as a reception address 21. Further, addresses (AD ₂ , AD ₄ ) for designating (transmitting) information 24 (data D ₂ , D ₄ , D ₆ ,..., D ₂₃ ) such as the elevator position to be transmitted from the main control device 6 a to each child device. , AD ₆ ,..., AD ₂₃ ) are defined as transmission addresses 23.

For example, three reception addresses 21 (AD ₂₀ , AD ₂₁ , AD ₂₂ ) are set for the information terminal 13, and each reception address 21 (AD ₂₀ , AD ₂₁ , AD ₂₂ ) is set. On the other hand, the information terminal 13 outputs three pieces of information 21 of write command data (D ₂₀ ), write position (D ₂₁ ), and write data (D ₂₂ ) to the transmission line 8. Further, one transmission address 23 (AD ₂₃ ) is set for the information terminal 13, and the display data D is transmitted from the main controller 6 a to the transmission line 8 following the transmission address 23 (AD ₂₃ ). ₂₃ information 24 is output.

The address output order memory 16 formed in the transmission control unit 14, as shown in FIG. 5, an address indicating the output order of the transmission path 8, 10 each address AD ₁ to be output to, AD _2, ..., AD ₂₃ The number N, the necessity of response to each address (the type of address described above), and the target child device are stored.

The output address reading unit 17 sequentially reads each address stored in the address output order memory 16 and sends it to the address output unit 18. As shown in FIG. 7C, the address output unit 18 sends the addresses AD ₁ , AD ₂ ,..., AD ₂₃ inputted from the output address reading unit 17 via the transmission / reception unit 19 to the transmission lines 8, 10. For example, the data is cyclically output at a constant time interval T _S such as 200 μs.

The data output unit 20, the address AD _1, AD _2, ..., the address for each transmission of the _{AD 23 23 (AD 2, AD} 4, AD 6, ..., AD 23) next to, for example, data input and output Information 24 (data D ₂ , D ₄ ) to be transmitted to each child device such as an elevator position obtained from the car movement control unit 26 and setting data (display data) obtained from the setting data memory 27 via the unit control unit 28. , D ₆ ,..., D ₂₃ ) are sent to the transmission lines 8 and 10.

Data extracting unit 25, the address AD ₁ outputted from the address output unit 18, AD _2, ..., address 21 for each reception of the _{AD 23 (AD 1, AD 3} , ..., AD 22) each to the next Information 22 (data D ₁ , D ₃ ,..., D ₂₂ ) such as each call (button operation) and write command data transmitted from the child device is extracted and sent to the data input / output control unit 28.

  The data input / output control unit 28 sends each input call (button operation) to the call assignment unit 29 or the car movement control unit 26, and sends the input write command data to the setting data memory 27.

Further, as shown in FIG. 7B, the data extraction unit 25 receives the reception address 21 after the reception address 21 and outputs the reception even after an allowable time T _{E of,} for example, 300 μs. If the information 22 (data D) to be received is not received by the transmission / reception unit 19, the output address reading unit 17 is notified.

  The output address reading unit 17 omits reading from the address output order memory 16 of the remaining addresses for the transmission source child device of the information 22 to be received, reads the address for the next child device, and sends it to the address output unit 18. Send it out.

For example, as shown in FIG. 7B, after the first reception address 21 (AD ₂₀ ) set in the information terminal 13, the write command data (D ₂₀ ) has an allowable time T _{E of} 300 μs. However, if it is not received, the output of the other addresses AD ₂₁ , AD ₂₁ , AD ₂₂ , AD ₂₃ and display data D ₂₃ set in the information terminal 13 is stopped, and the next child device. A receiving address 21 (AD ₁ ) is sent to the hall call registration device 7 on the first floor.

In the setting data memory 27, a large number of setting data including adjustment data for smoothly moving the elevator car 1 to the destination floor is stored. Then, the write command data (D ₂₀ ), the write position (D ₂₁ ), and the write data (D ₂₂ ) input from the data input / output control unit 28 from the information terminal 13 extracted by the data extraction unit 25. Adjust and change the setting data according to When the read command data (D ₂₀ ) and the read position (D ₂₁ ) are input by the data extraction unit 25, the setting data for the read position (D ₂₁ ) follows the transmission address 23 (AD ₂₃ ). Is sent to the data output unit 20 via the data input / output control unit 28 as display data (D ₂₃ ).

  The call assignment unit 29 assigns the hall call extracted by the data extraction unit 25 and input from the data input / output control unit 28 to the optimum elevator, and the assignment result is transmitted to the car via the data input / output control unit 28. The data is sent to the unit 26. Further, the data input / output control unit 28 sends the car call from the car call registration device 9 input from the data extraction unit 25 to the car movement control unit 26. The car movement control unit 26 sends to the driving unit 5 a drive signal for moving the elevator car 1 to the floor designated by the hall call and the floor designated by the car call. As a result, the car 1 starts moving to the destination floor.

FIG. 2 is a block diagram showing a schematic configuration of the information terminal 13 detachably provided on the transmission line 8. In this information terminal 13, a transmission control unit 30 for exchanging various information with the main control device 6 a through the transmission line 8 in a cyclic transmission manner, and each address AD ₂₀ , AD ₂₁ , AD ₂₂ set in itself. _, address memory 31, transmission path 8 setting data stored in the set data memory 27 of the main control unit 6a which is specified from the operation unit 32 at the maintenance personnel of the operation (display data D ₂₃₎ for storing the AD _23, the transmission A data reading unit 33 that displays the setting data (display data D ₂₃ ) read and read via the control unit 30 on its own display 34, and setting data writing specified by the operation unit 32 by the operation of the maintenance staff A data setting unit 35 is provided that transmits data (D ₂₂ ) to the main control device 6 a via the transmission control unit 30 and the transmission path 8 and sets the setting data in the setting data memory 27.

The transmission control unit 30 outputs write command data (D ₂₀ ) to the transmission path 8 when the address AD ₂₀ is output to the transmission path 8, and writes the write position (D ₂₀ ) when the address AD ₂₁ is output to the transmission path 8. D ₂₁ ) is output to the transmission path 8, and when the address AD ₂₂ is output to the transmission path 8, the write data (D ₂₂ ) is output to the transmission path 8, and when the address AD ₂₃ is output to the transmission path 8. Subsequently, display data D23 output to the transmission line 8 is taken.

FIG. 6 is a flowchart showing the overall operation of the main controller 6a. When the transmission process is started, the address number N of the address output order memory 16 is initialized (N = 1) (step S1). The address AD of the address number N in the address output order memory 16 is read and sent to the transmission lines 8 and 10 (S2). When the output address AD is a reception address 21 that requires a response from the slave device (S3), when the data D specified by the address AD is input (S5) before the allowable time _{TE has} elapsed (S4), The input data is transferred to the call input unit 28, the setting data memory 27, etc. (S6).

  Then, the address number N is updated (N = N + 1) (S7), and if the updated address number N does not exceed the maximum address number Na (= 23) of the address output order memory 16 (S8), S2 Then, the updated address AD of the address number N in the address output order memory 16 is read and sent to the transmission lines 8 and 10.

  If the updated address number N exceeds the maximum address number Na (= 23), the process returns to S1 to initialize the address number N in the address output order memory 16 (N = 1). Start outputting each address again.

If the data D specified by the address AD is not input before the allowable time T _E elapses in S4, the slave device to which this address AD is set is not connected to the transmission lines 8 and 10 or operates. Since it is a stop state, the address number N is updated (N = N + 1) (S9), and the updated address number N does not exceed the maximum address number Na (= 23) of the address output order memory 16 ( S10), the updated address AD of the address number N in the address output order memory 16 is read (S11). Then, it is determined whether or not the read address AD is an address for the same child device (S12). If the address AD is an address for the same child device, the process returns to S9 to update the address number N (N = N + 1).

  If the read address AD is not an address for the same child device, it is an address AD for the next child device, so this address AD is output to the transmission lines 8 and 10 (S13). Then, the process returns to S3, and it is determined whether or not the output address AD is a reception address 21 that requires a response from the child device. In the case of the transmission address 23 that does not require a response (S3), the information 24 (data D) determined by the transmission address 23 is output to the transmission lines 8 and 10 (S14). Thereafter, the address number N is updated (N = N + 1) (S7).

In the elevator transmission system of the first embodiment configured as described above, when the information terminal 13 is mounted on the transmission line 8, the main control device 6a, each child device, and the output on the transmission lines 8 and 10 are output. FIG. 7C shows the state of the addresses 21 and 23 and the information 22 and 24. In this case, the total time width T _A required by the information terminal 13 is 4 of the constant time interval T _S (= 200 μs) of the four addresses 21 and 23 (AD ₂₀ , AD ₂₁ , AD _22, AD ₂₃ ). Since it is doubled, T _A = 800 μs.

Next, a state where the information terminal 13 is removed from the transmission line 8 is shown in FIG. In this case, since the main control information 22 for the first address for receiving 21 (AD ₂₀₎ of the device 6a from the information terminal 13 (data D ₂₀₎ is not input, the allowable time T _E lapse of 300 [mu] s, the following first floor The address AD ₁ of the hall call registration device 7 is output. In this case, the total time width T _A required by the information terminal 13 is 300 μs of the allowable time T _E (T _A = 300 μs).

FIG. 7A shows a state where the information terminal 13 is removed from the transmission line 8 in the conventional transmission system shown in FIG. In this case, of the four addresses 21 and 23 (AD ₂₀ , AD ₂₁ , AD _22, AD ₂₃ ) set in the information terminal 13, three reception addresses 21 (AD ₂₀ , AD ₂₁ , AD ₂₂ ) Since the three pieces of information 22 (D ₂₀ , D ₂₁ , D ₂₂ ) are not input, the total time width T _A required by the information terminal 13 is T _A = 300 μs × 3 + 200 μ = 1100 μs.
It becomes.

  As described above, in the system according to the first embodiment of the present invention, the time can be shortened by 800 μs as compared with the conventional apparatus in the period T of about 3 ms with the information terminal 13 removed. Therefore, it is possible to prevent the information transmission cycle T between the remaining hall call registration devices 7 and the car call registration devices 9 and the main control device 6a from becoming significantly long, and the elevator responsiveness is improved for the elevator user. There is no decline.

Furthermore, as shown in FIG. 7B, when the operation of the hall call registration device 7 on the specific floor (second floor) is stopped so that the elevator does not stop on the specific floor such as the second floor, for example. also, only the first address AD ₃ of the second floor of the hall call registration device 7 plurality of addresses AD ₃ set for, AD ₄ is sent to the transmission path 8, the remaining address AD ₄ is not output . Therefore, even in such a case, as described above, it is possible to prevent the information transmission cycle T between the remaining child devices and the main control device 6a from becoming significantly long.

(Second Embodiment)
FIG. 8 is a block diagram showing a schematic configuration of the main controller 6b in the elevator system in which the elevator transmission system according to the second embodiment of the present invention is incorporated. The same parts as those of the main controller 6a of the first embodiment shown in FIG. 3 are denoted by the same reference numerals, and detailed description of the overlapping parts is omitted.

Similar to the data extraction unit 25 of the first embodiment shown in FIG. 3, the data extraction unit 25 in the main control device 6b of the elevator transmission system of the second embodiment receives data as shown in FIG. For example, if the information 22 to be received is not received by the transmission / reception unit 19 even after the allowable time T _{E of} 300 μs elapses after the reception address 21 is output, the output address reading unit 17a outputs Notice.

When the child device that is the transmission source of the information 22 to be received is the information terminal 13, the output address reading unit 17 reads the remaining three addresses AD ₂₁ , AD ₂₂ , and AD 23 for the information terminal 13 from the address output order memory 16. Is read out and the first address AD ₁ of the next-floor hall call registration device 7 is read out and sent to the address output unit 18. In addition, when the child device of the transmission source of the information 22 to be received is the hall call registration device 7 and the car call registration device 9 other than the information terminal 13, the second of the hall call registration device 7 and the car call registration device 9. The address is read and sent to the address output unit 18.

FIG. 9 is a flowchart showing the overall operation of the main controller 6b. When the transmission process is started, the address number N of the address output order memory 16 is initialized (N = 1) (step Q1). The address AD of the address number N in the address output order memory 16 is read and sent to the transmission lines 8 and 10 (Q2). When the output address AD is a receiving address 21 that requires a response from the slave device (Q3), the data D specified by the address AD is input (Q5) until the allowable time _{TE has} elapsed (Q4). The input data is transferred to the call input unit 28, the setting data memory 27, etc. (Q6).

  Then, the address number N is updated (N = N + 1) (Q7), and when the updated address number N does not exceed the maximum address number Na (= 23) of the address output order memory 16 (Q8), Q2 Then, the updated address AD of the address number N in the address output order memory 16 is read and sent to the transmission lines 8 and 10.

  When the updated address number N exceeds the maximum address number Na (= 23), the process returns to Q1, initialization of the address number N in the address output order memory 16 (N = 1) is performed, and the address output order memory 16 The output of each address is started again.

If the data D specified by the address AD is not input before the allowable time T _E elapses in Q4, the type of the child device to which this address AD is set is checked. When the child device is the information terminal 13 (Q9), the address number N of the head address AD in the next child device is obtained (Q10). Then, the address AD of the corresponding address number N is read from the address output order memory 16 and sent to the address output unit 18 (Q11). Then, returning to Q3, it is determined whether or not the output address AD is a receiving address 21 that requires a response from the slave device.

  When the transmission address 23 does not require a response (Q3), the information 24 (data D) determined by the transmission address 23 is output to the transmission lines 8 and 10 (Q12). Thereafter, the address number N is updated (N = N + 1) (Q7).

In the elevator transmission system of the second embodiment configured as described above, when the information terminal 13 is mounted on the transmission line 8, as shown in FIG. 10B, the same as in the first embodiment. In addition, the total time width T _A required by the information terminal 13 is four times the fixed time interval T _S (= 200 μs) of the four addresses 21 and 23 (AD ₂₀ , AD ₂₁ , AD _22, AD ₂₃ ). Therefore, T _A = 800 μs.

In the state of removing the information terminal 13 from the transmission path 8, the shown so in FIG. 10 (a), from the output of the start address AD ₂₀ of the information terminal 13 to the allowable time T _E lapse of 300 [mu] s, the following first floor The address AD ₁ of the hall call registration device 7 is output. In this case, the total time width T _A required by the information terminal 13 is 300 μs of the allowable time T _E (T _A = 300 μs). Therefore, substantially the same operational effects as those of the first embodiment described above can be achieved.

  In the second embodiment, the hall call registration device 7 and the car call registration device 9 other than the information terminal 13 are not removed from the transmission lines 8 and 10 in principle. Even if the information 22 (data D) is not received, the addresses 21 and 23 and information (data) for the second and subsequent times of the corresponding hall call registration device 7 and car call registration device 9 are output. That is, it is assumed that information (data) may be returned from the hall call registration device 7 and the car call registration device 9 for the second and subsequent reception addresses 21.

(Third embodiment)
FIG. 11 is a block diagram showing a schematic configuration of a main controller 6c in an elevator system in which an elevator transmission system according to a third embodiment of the present invention is incorporated. The same parts as those of the main controller 6a of the first embodiment shown in FIG. 3 are denoted by the same reference numerals, and detailed description of the overlapping parts is omitted.

In the address / information correspondence table 15a formed in the transmission control unit 14b of the third embodiment, as shown in FIG. 12, there are eight hall calls from the first floor (1F) to the eighth floor (8F). Addresses AD ₁ , AD ₂ ,..., AD ₂₀ set for a total of 10 child devices of the registration device 7, the car call registration device 9, and the information terminal 13, and information required by the corresponding address (button operation, command Data) and information (elevator position, lighting button) to be sent to each child device after the corresponding address are set.

However, only at the time of maintenance and inspection work, in the information terminal 13 mounted on the transmission line 8, the first reception address 21 (AD ₂₀ ) and information 22 requested by the corresponding address (button operation data D ₂₀ ) Only set.

Then, two pieces of information 21 required for actual maintenance inspection, the remaining two receiving addresses 21 (AD ₂₁ , AD ₂₂ ), the corresponding write position (D ₂₁ ), and write data (D ₂₂ ), Further, information 24 of one transmission address 23 (AD ₂₃ ) and display data (D ₂₃₎ is stored in the additional address / information correspondence table 15 b shown in FIG. An _{address number M is assigned to} the remaining three addresses AD ₂₁ , AD _{22, and} AD _{23 of the} information terminal 13 stored in the additional address / information correspondence table 15 b _.
Accordingly, in the address output order memory 16a, 20 addresses AD ₁ , AD ₂ ,..., AD ₂₀ set in the address / information correspondence table 15a, an address number N indicating the output order, and each Addresses AD ₁ , AD ₂ ,..., AD ₂₀ are set to indicate whether or not there is a response, and a total of ten child devices including the hall call registration device 7, car call registration device 9, and information terminal 13 to which the address AD ₁ , AD ₂ ,.

The output address reading unit 17b in the transmission control unit 14b in FIG. 11 sequentially reads each address stored in the address output order memory 16a and sends it to the address output unit 18. Furthermore, in the case of the information (data D20) extracted (received) by the data extraction unit 25, the output address reading unit 17b is configured to receive M addresses AD ₂₁ , AD ₂₂ , AD ₂₃ is sequentially sent to the read address output unit 18.

The data extraction unit 25, even after the lapse of the allowed time T _E from outputs an address 21 for receiving for example 300 [mu] s, the information 22 to be received is not received by the transmitting and receiving unit 19, the output address reading unit 17b Notice. The output address reading unit 17 reads the next address in the address output order memory 16a on the assumption that the child device of the transmission source of the information 22 to be received is not installed or is in an operation stop state, and sends it to the address output unit 18 Send it out.

15 and 16 are flowcharts showing the overall operation of the main controller 6c. When the transmission process is started, the address number N in the address output order memory 16a is initialized (N = 1) (step R1). The address AD of the address number N in the address output order memory 16a is read and sent to the transmission lines 8 and 10 (R2). When the output address AD is a reception address 21 that requires a response from the child device (R3), the data D specified by the address AD is input (R5) until the allowable time _{TE has} passed (R5). The input data is transferred to the call input unit 28, the setting data memory 27, etc. (R6).

If the input data is not the instruction data D ₂₀ from the information terminal 13 (R7), the address number N is updated (N = N + 1) (R8), and the updated address number N is stored in the address output order memory 16a. If the maximum address number Nb (= 20) is not exceeded (R9), the process returns to R2, reads the updated address AD of the address number N in the address output order memory 16a, and sends it to the transmission lines 8 and 10.

  When the updated address number N exceeds the maximum address number Nb (= 20), the process returns to R1, initializes the address number N of the address output order memory 16a (N = 1), and stores the address output order memory 16a. Start outputting each address again.

If the data D specified by the address AD is not input before the allowable time T _E elapses in R4, it is assumed that the child device that is the transmission source of the information 22 to be received is not attached or is in an operation stopped state. The address number N is updated (N = N + 1) (R8), and the updated address number N is output to the transmission lines 8 and 10.

  When the output address is a transmission address 23 that does not require a response (R3), information 24 (data D) determined by the transmission address 23 is output to the transmission lines 8 and 10 (R10). Thereafter, the address number N is updated (N = N + 1) (R8).

At R7, when input data is the instruction data D ₂₀ from the information terminal 13, since the transmission path 8 information terminal 13 is mounted, a subroutine (R11) of the additional address output process shown in FIG. 16 carry out.

  That is, in FIG. 16, the address number M in the additional address / information correspondence table 15b is initialized (M = 1) (R12). The address AD of the address number M in the additional address / information correspondence table 15b is read and sent to the transmission lines 8 and 10 (R13). When the output address AD is a reception address 21 that requires a response from the child information terminal 13 (R14), when the data D specified by the address AD is input (R15), the input write position data D21, The write data D22 is transferred to the setting data memory 27 (R16).

  Next, the address number M is updated (M = M + 1) (R17), and when the updated address number M does not exceed the maximum address number Mc (= 3) of the additional address / information correspondence table 15b (R18) ), Return to R13, read the updated address AD of the address number M in the additional address / information correspondence table 15b, and send it to the transmission lines 8 and 10.

  When the updated address number M exceeds the maximum address number Mc (= 3), the information exchange subroutine for the attached information terminal 13 in the communication cycle T is completed, and the process returns to R8 in FIG.

When the output address AD is a reception address 21 that does not require a response from the child information terminal 13 (R14), the information 22 (write data D ₂₂ ) determined by this reception address 21 is transferred to the transmission line 8, 10 (R19). Thereafter, the address number N is updated (M = M + 1) (R17).

In the elevator transmission system according to the third embodiment configured as described above, the address / information correspondence table 15a includes the first receiving address AD ₂₀ for requesting the instruction data D ₂₀ as the address of the information terminal 13. Only set. The remaining addresses are set in the additional address / information correspondence table 15b.

Therefore, in a normal state where the information terminal 13 is not attached to the transmission line 8 and maintenance is not performed, as shown in FIG. 17A, 300 μs from the output of the head address AD ₂₀ of the information terminal 13 The address AD ₁ of the next first-floor hall call registration device 7 is output after the allowable time _{TE has} elapsed. In this case, the total time width T _A required by the information terminal 13 is 300 μs of the allowable time T _E (T _A = 300 μs).

In addition, since the information terminal 13 is attached to the transmission line 8 during the maintenance inspection period, as shown in FIG. 17B, the information terminal 13 needs the same as in the first embodiment. Since the total time width T _A is four times the fixed time interval T _S (= 200 μs) of the four addresses 21 and 23 (AD ₂₀ , AD ₂₁ , AD _22, AD ₂₃ ), T _A = 800 μs. Become.

Thus, in a normal state where no conduct maintenance, compared to the period in which the information terminal 13 is performing the maintenance time width T _A total in need, it is possible to greatly reduce, the above-described The same operational effects as those of the first and second embodiments can be obtained.
