It is designed to lift and carry luggage.

With reference to FIG. 1, the basic configuration of the system according to the first embodiment will be described.
This system is composed of an in-vehicle controller 10 mounted on the forklift 1 and a server 20 installed in the management center 2 for exchanging data with the controller 10 using a communication line.
When there are a plurality of forklifts 1, a controller 10 is mounted on each. For example, the management center 2 is operated by a company that manages the work site, is operated by a manufacturer that manufactures the management system, or is operated by a company that provides maintenance / management services to the management system. Etc.

In this system, the running operation state or the cargo handling operation state of the forklift 1 is detected, vehicle data corresponding to these detection signals is recorded in the in-vehicle controller 10, and the vehicle data is stored using wireless communication at a predetermined timing. Send to server 20. The predetermined timing is when the key switch of the forklift 1 is in the OFF state. That is, as shown in FIG. 3, if one vehicle operating period unit is recorded between immediately after the key switch is turned ON and immediately before it is turned OFF, vehicle data in one vehicle operating period unit is recorded, and this is recorded. Save as the vehicle running period units data filing, it is key is OFF and the vehicle operation period unit data to be transmitted to the server 20.

And the vehicle data including vehicle operation period unit data are output from the database 21 as needed. This vehicle data can be used effectively for planning and correcting the operation plan of the forklift 1, grasping the maintenance time and frequency, or safety measures.

FIG. 2 shows a specific configuration of this embodiment. In the figure, various devices included in the forklift 1 and the internal configuration of the in-vehicle controller 10 mounted on the forklift 1 are shown, and the internal configuration of the server 20 installed in the management center 2 is shown.
The forklift 1 includes a traveling / loading operation detector 18, a power key switch 19, and an in-vehicle controller 10.

The traveling / loading operation detector 18 is a device for detecting the traveling operation state and the cargo handling operation state of the forklift 1. This device is forklift travel speed, engine operation state (output, rotation speed, cooling water temperature, lubricating oil temperature, etc.), running operation such as operation time and stop time, lift cylinder mounted on forklift 1, tilt The operation state of the operation equipment such as the cylinder and the operation time, that is, the operation action such as the operation oil pressure, the hydraulic oil temperature, and the operation time of each operation equipment is detected. Specifically, a vehicle speed sensor, a load sensor, a cargo handling operation detection sensor, etc. are mentioned.
The power key switch 19 is a device for instructing start / stop of the engine or motor of the forklift 1.

The in-vehicle controller 10 includes a travel / load handling operation input unit 101, a storage unit 102, a power supply monitoring unit 103, a control unit 104, and a wireless communication unit 105.
The traveling / loading operation input unit 101 has a function of inputting a detection signal from the traveling / loading operation detector 18 into the controller as vehicle data.
The storage unit 102 periodically records (logs) and stores the vehicle data input from the traveling / loading operation input unit 101. The log period is within a period from immediately after the power key switch 10 is turned on to immediately before the power key switch 10 is turned off.
The power monitoring unit 103 detects the ON / OFF state of the power key switch 19. When the power monitoring unit 102 detects the key switch OFF signal, the power monitoring unit 102 instructs the storage unit 102 to complete the log and save the logged data as a file.
The filed vehicle data is temporarily stored in the storage unit 102 until it is transmitted to the server 20 at the next OFF time. If communication is impossible, the vehicle data is further stored until the next OFF time. Moreover, the vehicle data after transmission to the server 20 may be deleted each time or may be overwritten and saved as needed.

The wireless communication unit 105 determines whether or not the forklift 1 (controller 10) is within a communicable range using a wireless line. If the forklift 1 is within the communicable range, a connection with the server 20 is established. It is a communication interface for exchanging data with the server 20 using a wireless line.
In the present embodiment, the in-vehicle controller 10 is configured to connect to a server using a wireless LAN system. That is, a wireless relay device 31 connected to a communication line such as the Internet is installed at or around the work site, and it is determined whether or not the forklift 1 exists within a communicable range centering on the relay device 31. This is determined by the communication unit 105.

The control unit 104 includes a CPU that controls various devices, a ROM in which various numerical values and programs are written in advance, a RAM in which numerical values and flags of calculation processes are written in a predetermined area, and a bus to which these devices are connected. It is composed of lines.
As the functions executed by the control program written in advance in the ROM, the traveling / loading operation input unit 101, the storage unit 102, the power supply monitoring unit 103, and the wireless communication unit 105 are shown.

The management center 2 is provided with a server 20 and a database 21 connected thereto. The server 20 includes a data update unit 201, a cumulative calculation unit 202, a data analysis unit 203, an output unit 204, an input unit 205, a control unit 206, and an external communication unit 207.
The input unit 205 performs input operations such as a keyboard, a mouse, and a touch panel. The output unit 204 outputs requested vehicle data. For example, the data is printed on a display for displaying a screen or on paper. A printer or the like.

Similar to the control unit 105 of the controller 10 described above, the control unit 206 is a CPU that controls various devices, a ROM in which various numerical values and programs are written in advance, and numerical values and flags of calculation processes are written in predetermined areas. The RAM is composed of a bus line to which these devices are connected.
In addition, a data update unit 201, a total calculation unit 202, and a data analysis unit 203 are shown as functions executed by a control program written in advance in the ROM.
When the data update unit 201 newly receives vehicle data from the controller 10, the data update unit 201 updates corresponding received data as needed.
The cumulative calculation unit 202 accumulates the vehicle data stored in the database 21 for a predetermined period and acquires long-term data.
The data analysis unit 203 performs predetermined calculation processing as necessary to obtain desired vehicle data.

The database 21 stores vehicle data received from the controller 10. As the vehicle data stored in the database 21, in addition to vehicle operation period unit data (stored file of one vehicle operation period unit ), long-term data obtained by the cumulative calculation unit 202, or vehicle at a certain time point There is instantaneous data consisting of data. The type of vehicle data will be described later.

In addition, the database 21 includes a handling value including a permissible value (range) or a reference value (range) of a travel operation including a permissible operation time of the forklift 1 and a limit value of the vehicle travel speed, and a load weight limit value in a cargo handling operation. An allowable value (range) or a reference value (range) is preset.
For example, when an allowable value of the vehicle speed is set, vehicle speed data is extracted from the vehicle data stored in the database 21, and the data analysis unit 203 compares the vehicle speed data with the allowable value of the vehicle speed. If the vehicle speed data exceeds the allowable value, it is determined that the vehicle is in danger driving. The number of times of dangerous driving may be counted for each period and output as the number of vehicle speed overruns.
The external communication unit 207 is a communication interface for connecting to the communication line 51 such as the Internet and exchanging data with the controller 10.

Next, processing operations in the system having the above-described configuration will be described.
When the power key switch 19 is turned ON at the start of operation of the forklift 1, an ON signal is detected by the power supply monitoring unit 103 of the controller 10, and recording of vehicle data is started. Vehicle data is recorded and stored in the storage unit 102 of the controller 10 based on a detection signal from the traveling / loading operation detector 18. This is preferably set to record vehicle data at regular intervals. The vehicle data to be recorded is data corresponding to a data item designated in advance by the server 20.

When the key switch is turned off due to the end of the work or the pause, the power monitoring unit 103 detects the OFF signal, and the vehicle data recorded so far is filed and stored in the storage unit 102. Further, the wireless communication unit 104 determines whether or not the communication range is within the communicable range. If the radio communication unit 104 is within the communicable range, the storage file is transmitted to the server 20. If it is not within the communicable range, the connection with the server 20 is not established, and the stored data is stored in the storage unit 102. This stored data is accumulated until the next OFF.
Here, the processing operation of the controller 10 when the key switch is OFF is shown in FIG.
When the controller 10 detects the key switch OFF signal (S1), it determines whether or not it is within the communicable range (S2). If it is determined that it is out of the communicable range, has the set time until the power is turned off passed? Or is there no stored data? (S3), if the set time until the power is turned off has not elapsed, or if there is stored data, retry is made again after a predetermined time (S4). The set time until the power is turned off is set in the environment setting file in the controller 10 in advance.
When the set time until the power is turned off or when there is no stored data, the power is turned off (S5).

  When it is determined whether it is within the communicable range (S2), if it is within the communicable range, it is determined whether there is stored data in the storage unit 102 of the controller 10 (S6). If there is no stored data, the power is turned off (S7). If there is stored data, the server connects to the server (S8). If the connection fails, the process returns to the communication range check step (S2) again. When the connection to the server is established, the vehicle data is transmitted to the server 20 (S9). When all the data has been transmitted, the process returns to the stored data confirmation step (S6), and after confirming that no stored data remains, the power is turned off (S7). If the communication state is poor and communication is interrupted without completing the data transmission, the process returns to the communicable range confirmation step (S2) and the above-described processing flow is performed again. In this flow, the order of the communicable confirmation step (S2) and the stored data confirmation step (S6) may be reversed.

As described above, when the key switch OFF signal is detected, the vehicle data is transmitted to the server 20 before the power is turned OFF. When transmission of all the vehicle data stored in the storage unit 102 of the controller 10 is completed, the power is turned off.
By performing the processing operation described above, it is possible to reliably transmit the vehicle data stored in the storage unit 102 to the server 20 even when the communication state is bad.

Further, as a configuration for executing the processing flow, it is preferable that the power supply monitoring logic and the wireless communication logic are configured to operate independently. Here, the power supply monitoring logic is a process of monitoring the ON / OFF signal of the key switch in real time, and saving the vehicle data record in the storage unit 102 when it is OFF. The wireless communication logic is a process of monitoring whether communication is possible and transmitting data by connecting to a server if communication is possible and vehicle data is stored.
FIG. 5 shows a flowchart of the power supply monitoring logic, and FIG. 6 shows a flowchart of the wireless communication logic.

  First, the power supply monitoring logic will be described with reference to FIG. A counter initial value is set in advance in the environment setting file of the controller 10. The counter initial value is substituted from the environment setting file into the counter of the ON / OFF detection unit 103 (S11), and the counter is subtracted from it (S12). When the key switch ON signal is detected (S13), the counter is reset to the initial value. When the key switch OFF signal is detected, it is determined whether or not the counter is 0 (S14). If the counter is 0 or more, it is confirmed whether or not the recording (logging) of the vehicle data is completed (log). S15). If the recording has not been completed, the process returns to the counter subtraction step (S12). If the log is completed, the vehicle data is stored (S16), and it is determined whether there is stored data (S17). If there is stored data, the process returns to the counter subtraction step (S12). When the counter subtraction step (S12) is repeated several times, the counter becomes zero. When the counter reaches 0, it is considered that a predetermined time has elapsed, and the power is turned off (S18). Further, in the stored data confirmation step (S17), the power is turned off even when there is no stored data (S18).

Next, the wireless communication logic will be described with reference to FIG. When the key switch is in the ON state (S21), it is determined whether or not it is within the communicable range (S22). If it is out of the communicable range, a retry is performed (S23). If it is within the communicable range, it is checked whether there is data saved by the power monitoring logic (S24). If there is saved data, the server 20 is connected (S25). If the server connection fails, the process returns to the communication enable determination step (S22). When the connection to the server 20 is successful, the stored vehicle data is transmitted to the server (S26), and when all the data has been transmitted, the communication is completed (S27).
As described above, by configuring the power supply monitoring logic and the wireless communication logic to operate independently, it is possible to cope with an unexpected state such as a power interruption during data transmission.

The vehicle data transmitted to the server 20 in this way is subjected to arithmetic processing as necessary and stored in the database 21. Data types to be stored in the database 21, as shown in FIG. 3, the vehicle operation period unit data collected during the key switch ON, the instantaneous consisting vehicle data at the time of certain of the vehicle running periods unit data There are data and long-term data obtained by accumulating vehicle operation period unit data for a predetermined period.

Here, the data types of the vehicle data stored in the database 21 are shown. The data types include vehicle operation period unit data that is vehicle data in one vehicle operation period unit , long-term data in which the vehicle operation period unit data is accumulated by the accumulation calculation unit 202, and the vehicle operation period unit data. Among them, there is instantaneous data composed of vehicle data at a certain point in time. Instantaneous data is obtained by extracting data at a temporary point corresponding to a predetermined condition in the data analysis unit 203. For example, the vehicle speed when the reference speed is exceeded within a certain period.
FIG. 7 shows a specific example of long-term data stored in the database 21. The figure is a vehicle data item table, in which a machine number for identifying the forklift 1 and vehicle data corresponding to this are stored. The vehicle data shown here is long-term data obtained by accumulating vehicle operation period unit data. In the figure, the operating time (h) is the total operating time per day, the mileage (km) is the total driving distance per day, the seating rate (%) is the sitting time in working days, and the occupancy rate (%) is Operating hours in working days, loading rate (%) is loading time in working days, driving rate (%) is forward / reverse lever operating time in working days, fuel consumption (L / h) is fuel consumption during cumulative operating hours, vehicle speed (Km / h) is the cumulative travel distance during the cumulative operation time, vehicle speed over (times / h) is the number of vehicle speed overruns during the cumulative operation time, cargo handling rate (%) is the empty cargo liquid travel time during the cumulative operation time, idle The rate (%) is the number of hours during which the engine is stopped / unloading during the cumulative operation time, and the seating idle ratio (%) is the number of times the engine speed is above the specified value during the neutral operation / stopping / loading operation without the forward / reverse lever. , The number of air blows (times / day) is cumulative In row time is the number of times the engine speed is more than specified by the forward-reverse lever without neutral, stop and load-handling state.

Among these data, in particular, the seating rate, operating rate, loading rate, travel rate, cargo handling rate, idle rate, seating idle rate, and idling rate are compared with other vehicles and are comprehensively evaluated among multiple vehicles. This makes it easy to improve the efficiency of the operation plan, reduce costs, and propose safety measures. It is preferable to calculate and accumulate these.
By making such long-term data into a database and outputting it, it is possible to instantly grasp the operation status and operation history of the forklift, formulate and correct the optimal operation plan of the forklift, grasp the maintenance time, or implement safety measures Is possible.

FIG. 8 shows an example of setting a period. As described above, a period, which is one unit of vehicle data, refers to a period from immediately after the key switch is turned on to immediately before it is turned off.
In this embodiment, this period may be set for each work type to which the work type or work area is applied, or may be set for each work area.
In general, when a plurality of forklifts are used, work contents and work areas are determined to some extent for each forklift. In addition, work contents are often determined for a certain period. For example, as shown in FIG. 8, the forklift 1A loads and unloads from the delivery vehicle 55 and transports it to the delivery location, and the forklift 1B performs the entry or exit operation from the delivery location to the storage location. As described above, work contents and work areas are almost determined for each forklift.

  Therefore, by setting the work type or work area as a period, it becomes possible to easily compare between multiple forklifts, and it is possible to detect variations in operation status in the same work type or the same work area. Can be easily grasped.

FIG. 9 illustrates a basic configuration of a system according to the second embodiment. In the second embodiment, detailed description of the same configuration as that of the first embodiment will be omitted.
In the second embodiment, the controller 10 mounted on the forklift 1, the server 20 installed in the management center 2, the database 21 connected to the server 20, the server 20 and a communication line 50 such as the Internet are used. The main configuration is the user-side communication terminal 40 that exchanges data.
In this system, vehicle data stored in the database 21 of the server 20 can be output to the user side communication terminal 40. Further, the user-side communication terminal 40 can selectively receive the vehicle data in the database 21 as necessary, and can output a screen display or the like.

The user side communication terminal 40 selects a necessary data item from the data items presented by the server 20 and requests the server 20 for vehicle data corresponding to the selected data item via the communication line. In response to this request, the server 20 extracts the corresponding data item from the database 21 and transmits the extracted vehicle data to the user side communication terminal 40. The user-side communication terminal 40 receives the vehicle data and outputs it by displaying it on a display screen. At this time, it is preferable that the data items to be displayed among the received data items can be further selected.
FIG. 10A shows vehicle data stored in the database 21, and FIG. 10B shows vehicle data output to the user side communication terminal 40. As shown in these figures, by making it possible for the user to freely select data to be collected from the vehicle data stored in the database 21, only necessary data is output for each user. It becomes easy to grasp the operation status.

  In this embodiment, even in a work environment where there are many obstacles, the necessary vehicle data can be reliably collected by wireless communication, and the operation status can be easily compared among a plurality of industrial vehicles.
