It is steered by being driven.

  As shown in FIG. 2, the forklift 1 is equipped with a control device 20 as a traveling cargo handling controller for controlling traveling and cargo handling operations, and a management device 30 according to the present embodiment. In the forklift 1, on the basis of a control command from the control device 20, the travel and load handling system actuators such as the travel motor 9, the tilt cylinder 5, and the lift cylinder 6 are operated.

  Further, the forklift 1 is provided with an accelerator pedal 21 that generates a travel command based on an operation of an operator (driver) who operates the forklift 1, and the accelerator pedal 21 includes an operation amount ( An accelerator sensor 22 that detects the amount of depression) is provided. The forklift 1 is also provided with a brake pedal 23 that generates a braking command based on the operation of the driver of the forklift 1, and the brake pedal 23 detects a brake pedal 23 operation amount (depression amount). A sensor 24 is provided. As the accelerator sensor 22 and the brake sensor 24, for example, a potentiometer is used. Both the accelerator sensor 22 and the brake sensor 24 are connected to the control device 20 and the management device 30, respectively. And the control apparatus 20 controls the action | operation of the traveling motor 9 based on the command from these sensors (22, 24). On the other hand, the management device 30 manages the driving operation state as will be described later based on the commands from these sensors (22, 24).

  Next, the electrical configuration of the management device 30 of the forklift 1 will be described based on the block diagram of the management device 30 shown in FIG. The management device 30 includes a CPU (central processing unit) 31, a ROM (read only memory) 32, a RAM (read / write memory) 33, a real time clock IC 34, a backup battery 35, an accelerator detection interface (accelerator detection I / F). ) 36, a brake detection interface (brake detection I / F) 37, a communication interface (communication I / F) 38, and the like.

  An output from the accelerator sensor 22 is input to the CPU 31 via the accelerator detection interface 36, and an output from the brake sensor 24 is input via the brake detection I / F 37.

  The ROM 32 stores a program for processing as the management device 30 and is read and executed by the CPU 31 as appropriate. Further, the RAM 33 stores data generated by executing a program for processing the management device 30. Note that a backup battery 35 is connected to the RAM 33 so that power is supplied from the backup battery 35 when the power supply is cut off, so that stored data is not lost.

  The real time clock IC 34 is connected to the CPU 31, measures time, and inputs data related to time to the CPU 31. Note that a backup battery 35 is connected to the real-time clock IC 34, and power is supplied from the backup battery 35 when power supply is cut off.

  The communication interface 38 outputs data generated by execution of a program for processing as the management device 30 to the computer (terminal device) 60 connected to the outside. The communication interface 38 may be wireless communication or wired communication.

  In the management device 30, the following units (41 to 47) are constructed by combining the hardware and software described above.

  FIG. 4 is a functional block diagram showing the configuration of the management device 30. As shown in FIG. As shown in the figure, the management device 30 includes a command detection unit 41, a simultaneous operation detection unit (simultaneous operation detection unit) 42, a simultaneous operation amount calculation unit (simultaneous operation amount calculation unit) 43, and a storage unit (memory). Means) 44 and a communication unit (communication means) 45.

  The command detection unit 41 includes the accelerator detection I / F 36 and the brake detection I / F 37 described above. The accelerator detection I / F 36 constitutes a travel command detection means for detecting a state in which a travel command for the forklift 1 is issued. When the operation amount of the accelerator pedal 21 is detected by the accelerator sensor 22, the detection signal of the accelerator sensor 22 is input to the accelerator detection I / F 36. Based on this input, the accelerator detection I / F 36 detects that the accelerator pedal 21 is being operated (that is, the travel command for the forklift 1 is being issued). When a state in which a travel command is issued is detected, the accelerator detection I / F 36 outputs a travel command detection signal A to the simultaneous operation detection unit 42 during that time.

  On the other hand, the brake detection I / F 37 of the command detection unit 41 constitutes a braking command detection unit that detects a state in which a braking command for the forklift 1 is issued. When the operation amount of the brake pedal 23 is detected by the brake sensor 24, the detection signal of the brake sensor 23 is input to the brake detection I / F 37. Based on this input, the brake detection I / F 37 detects that the brake pedal 23 is being operated (that is, the brake command for the forklift 1 is being issued). When a state in which a braking command is issued is detected, the brake detection I / F 37 outputs a braking command detection signal B to the simultaneous operation detection unit 42 during that time.

  The simultaneous operation detection unit 42 detects a simultaneous operation state in which both the travel command and the braking command for the forklift 1 are simultaneously issued based on the detection result of the command detection unit 41. That is, the simultaneous operation detection unit 42 detects a state in which the travel command signal A is input from the accelerator detection I / F 36 and the brake command signal B is input from the brake detection I / F 37 as a simultaneous operation state. . FIG. 5 is a schematic diagram for explaining a situation in which a simultaneous operation state is detected. FIG. 5 shows the situation in which the simultaneous operation detection unit 42 detects the traveling command detection signals A1 and A2 in order at intervals and the braking command detection signals B1 and B2 are detected in order at intervals. It is shown along the horizontal axis corresponding to. In the situation shown in FIG. 5, a section X in which both the travel command detection signal A2 and the braking command detection signal B2 are input is generated, and the simultaneous operation detection unit 42 performs the same while the section X is generated. Detect as operation status. That is, in this section X, the driver of the forklift 1 is simultaneously operating the accelerator pedal 21 and the brake pedal 23, and is in a state where both the travel command and the brake command are issued. The simultaneous operation detection unit 42 detects the simultaneous operation state.

  Based on the detection result detected by the simultaneous operation detection unit 42, the simultaneous operation amount calculation unit 43 uses the time data from the real-time clock IC 34 as the simultaneous operation generation amount that is a value indicating the degree of occurrence of the simultaneous operation state. Is calculated for each predetermined unit time based on the input. The simultaneous operation amount calculation unit 43 includes an occurrence number calculation unit 46 and an accumulated time calculation unit 47. The predetermined unit time can be appropriately set according to the work environment and the like. For example, various unit times such as a unit of 10 minutes, a unit of 1 hour, a unit of half a day, a unit of 1 day, and a unit of working hours for workers can be set.

  The number-of-occurrence calculation unit 46 calculates the number of occurrences of the simultaneous operation state (hereinafter simply referred to as “the number of occurrences of simultaneous operation”), which is the number of times (the number of times) the simultaneous operation state is detected by the simultaneous operation detection unit 42. The operation generation amount is calculated every predetermined unit time. For example, assuming that the predetermined unit time is 1 hour, the number of times that the section X (simultaneous operation state) as shown in FIG. 5 occurs during each hour is calculated.

  On the other hand, the integration time calculation unit 47 calculates the integration time of the simultaneous operation state (hereinafter simply referred to as “simultaneous operation integration time”), which is an accumulated value obtained by integrating the time during which the simultaneous operation state is detected by the simultaneous operation detection unit 42. The amount of simultaneous operation is calculated every predetermined unit time. For example, assuming that a section X as shown in FIG. ΔT1 + ΔT2 + ΔT3 ”.

  The storage unit 44 is configured by the RAM 33, and the simultaneous operation generation amount calculated per unit time by the simultaneous operation amount calculation unit 43, that is, the simultaneous operation generation number calculated by the generation number calculation unit 46 and the integrated time calculation unit 47. And the simultaneous operation integration time calculated in the above are stored. An example of a method for storing the simultaneous operation generation amount (number of simultaneous operation occurrences and simultaneous operation integration time) in the RAM 33 is, for example, when the predetermined unit time is 1 hour, the time when the operation of the forklift 1 is started is 200X. When it is 9:00 on November 1st of the year, the simultaneous operation generation amount for 1 hour from 9:00 is stored. When 1 hour elapses from 9:00 and reaches 10:00, storage of the simultaneous operation generation amount from 10:00 to 1 hour is started. Thereafter, the simultaneous operation generation amount is stored every hour. Even if the operation of the forklift 1 is temporarily interrupted in the middle of any unit time and the power supply to the management device 30 is cut off, the RAM 33 holds the data by the backup battery 35. Therefore, there is no problem with handling as data in the unit time when the interruption occurred. In addition, when driving | operation is interrupted in the middle of unit time, unit time can be measured except for the interrupted time, and it can also be made to memorize | store the simultaneous operation generation amount. In this case, even if the operation interruption and resumption of operation of the forklift 1 are frequently repeated, the simultaneous operation generation amount can be continuously stored without any trouble.

  The communication unit 45 includes a communication I / F 38 and transmits data stored in the storage unit 44 to the computer (terminal device) 60. The storage unit 44 may delete data from the RAM 33 by transmitting data to the computer 60 and store new data. Alternatively, when the storage address of the RAM 33 overflows regardless of the presence or absence of transmission, the data is returned to the top address and overwritten and recorded, and only the data according to the request from the computer 60 is retrieved from the storage unit 44 and transmitted. You may do it.

  In the computer 60, the amount of simultaneous operation generation (number of simultaneous operation occurrences, simultaneous operation integration time) can be grasped from the data received from the communication unit 45. 6 and 7 illustrate management data displayed on a predetermined screen of the computer 60 connected externally. In the example of FIGS. 6 and 7, the simultaneous operation generation amounts in a plurality of forklifts (units 1 to 3) on a specific day (XX year XX month XX day) are displayed in a graph. In the display example of FIG. 6, the number of simultaneous operation occurrences is displayed as a graph. In the display example of FIG. 7, the simultaneous operation integration time is displayed as a graph.

  8 and 9 exemplify other management data displayed on the computer 60. FIG. The examples of FIGS. 8 and 9 are graphs showing the simultaneous operation generation amount on a specific forklift (XX machine) on a specific day (XX year XX month XX day). Unlike the case of FIG. 7, the simultaneous operation generation amount for each predetermined unit time (1 hour in the examples of FIGS. 6 and 7) is displayed together with the time zone. In the display example of FIG. 8, the number of simultaneous operation occurrences is displayed as a graph, and in the display example of FIG. 9, the simultaneous operation integration time is displayed as a graph.

  As shown in FIGS. 6 to 9, the computer 60 can grasp the occurrence status of the simultaneous operation state in the forklift 1. Therefore, by collecting information from a plurality of forklifts 1 in a remote place, it is possible to centrally manage the occurrence status of the simultaneous operation state of each forklift 1. Moreover, the forklift 1 can be individually managed by collecting information from the individual forklifts 1 as necessary. Also, as shown in FIGS. 6 to 9, by visualizing the amount of simultaneous operation generated, it is possible to easily grasp the occurrence state of the simultaneous operation state.

  As described above, according to the industrial vehicle management device 30 according to the present embodiment, it is possible to grasp the occurrence status of the simultaneous operation state in which both the travel command and the braking command are issued simultaneously. The occurrence of a state in which the travel command and the braking command are issued simultaneously, that is, simultaneous operation of the accelerator pedal 21 and the brake pedal 23 causes overheating of the travel motor 9 that is the travel drive device. Become. For this reason, damage due to heat generation of the traveling motor 9 is likely to occur, and a traveling state that induces a failure of the traveling motor 9 is generated. Therefore, from the viewpoint of whether or not normal driving operation is performed without generating a traveling state that induces a failure in relation to the operation of the forklift 1 by being able to grasp the occurrence state of the simultaneous operation state. Can be managed, and can also be used for guidance to workers. Further, since such management is possible and can be used for guidance to the worker, the effect of suppressing the overheating of the traveling motor 9, the effect of reducing the damage caused by the heat generated by the traveling motor 9, and the maintenance load The reduction effect can be expected.

  Moreover, according to the management apparatus 30, since the simultaneous operation generation frequency can be managed as the simultaneous operation generation amount, the occurrence state of the simultaneous operation state can be more appropriately grasped according to the occurrence frequency. Furthermore, according to the management device 30, since the simultaneous operation integration time can be managed as the simultaneous operation generation amount, the occurrence state of the simultaneous operation state can be more appropriately grasped according to the time when the simultaneous operation state is generated. Moreover, according to the management apparatus 30, the generation | occurrence | production situation for every unit time of a simultaneous operation state can be grasped | ascertained, and the generation | occurrence | production state of the simultaneous operation state in relation to a work time zone can be managed.

(4) The simultaneous operation amount calculation unit may determine a plurality of braking commands by a braking operation repeated a plurality of times in a short time like a pumping brake operation as one braking command. In this case, for example, if the next braking command is generated after a predetermined short time has elapsed after the braking command has been generated, these braking commands are determined as one continuous braking command. You may do.
