Description

  The present invention relates to a vehicle-mounted device and a work management system, and more particularly to a technique for detecting an abnormality in a work of a crew member or a worker.

  For example, in a company that manages the operation of a truck, a bus, a taxi vehicle, etc., it is necessary to manage the operation state of each vehicle, and to perform labor management and safe driving management for each crew who drives each vehicle.

  Therefore, in order to make it possible to grasp the actual operating condition of the vehicle, an on-board unit such as a digital tachograph which is an operation recorder is mounted on each vehicle. Such an on-vehicle device automatically collects various operation data, and records and stores the operation data on a recording medium such as a memory card.

  Further, for example, the operation management system of Patent Document 1 shows a technique useful for the manager on the office side to warn a crew member in advance when the continuous travel time is likely to exceed the time limit. That is, the digital tachograph counts the continuous running time Ta of the vehicle, and when the continuous running time Ta reaches the notice time T1 set 30 minutes before the time limit T2, sends a notice event to the office PC . When receiving the advance notice event, the office PC displays a message of the continuous drive advance notice as emergency information on the screen of the display unit.

  Further, the on-vehicle recording apparatus and the management system of Patent Document 2 show a technique for correctly managing the crew for "rest time" which may change depending on the situation in labor management of the crew. In other words, the on-vehicle recording device includes a clock processing unit, an operation unit having a plurality of operation locations that receive input operations by the driver, and a data processing unit that causes the time counting unit to time different time lengths according to the input operations on the plurality of operation locations. And a voice interface for informing the driver that the clocking by the clocking unit has ended. Further, when the clocking is finished, the on-board recording device transmits end information representing it to the office PC via the wireless communication unit. In the time adjustment mode, assignment of an arbitrary designated time length is permitted for each of a plurality of operation points. In addition, the information indicating the length of the remaining time is broadcasted from the start of time counting to the end of time counting.

  Further, the operation recording device and the operation management system of Patent Document 3 show a technique for preventing the provision of operation data, which is less necessary from the viewpoint of operation management of a vehicle, to an external device. That is, the operation recording apparatus includes a control unit which records operation data including a crew ID and information on operation of a vehicle and provides the operation data to an external device. When the vehicle is operated in the case where the crew ID can not be acquired, the control unit records temporary operation data including information that the crew is not specified, and temporarily operates if the operation of the vehicle satisfies a predetermined effective condition. The data is provided to the external device, and the temporary operation data is not provided to the external device if the operation of the vehicle does not satisfy the effective condition. As the effective condition, at least one of whether the operation time of the vehicle is the threshold time or more and whether the moving distance of the vehicle is the threshold distance or more is used.

  When adopting the technique of the above-mentioned patent documents 1, it can manage so that the continuous run time of a crew member may not exceed the upper limit defined by the law. Further, in the case of adopting the technology of Patent Document 2, since the "rest time" of the crew can be managed, labor management of the crew becomes easy. Further, by adopting the technology of Patent Document 3, it is possible to appropriately manage data recording during operation of a vehicle.

  However, there is no technology for detecting the occurrence of unexpected events for operations performed by crew members or workers when the vehicle is at a standstill, and such functions do not require the use of onboard vehicles such as digital tachographs. It is not included in the bowl.

  For example, in the case of a vehicle operation operation that transports various packages by truck, after crews and other workers load the packages onto the truck in the warehouse of the shipper, according to a predetermined schedule, it is directed to the destination It will start the operation of the truck. However, there is also a possibility that an unexpected event may occur in the operation (loading) of loading a load onto a truck bed. For example, an accident may occur during operation in which a crew member, a worker, a luggage, etc. fall from a loading platform, or a crew member or a worker is caught in the luggage.

  When such an accident occurs, it is necessary to rescue the injured person immediately. However, for example, when a crew member is carrying out loading work alone, there is a possibility that no one else can know the occurrence of the accident and can not notify anyone of the occurrence of the accident. In addition, the manager who manages the operation of the vehicle is also usually able to grasp that a delay has occurred by analyzing the operation data later, and also in real time via the network Even if the operation data is received, it can only know that the operation of the vehicle is slightly behind the schedule, and can not know the occurrence of the accident.

  In addition, not only loading and unloading operations, but also unexpected events may occur, for example, during a passenger's rest time, such as robbery or damage caused by a disaster or the like. Also in this case, there is a possibility that no one other than the crew can know the occurrence of the damage, nor can it be reported to anyone.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide an on-vehicle device and a work that are useful for quickly responding to unexpected events such as occurrence of an accident during work while the vehicle is stopped.

<Description of characteristic features of the system>
<Configuration Example of Operation Unit>
The digital tachograph 10 shown in FIG. 1 is a special tachograph 10 for monitoring an abnormality related to the work of a crew member, a break or the like when the vehicle is stopped, and notifying the office PC 30 etc. when an abnormality is detected. It has a function. An operating unit 80 is provided on the front panel of the housing of the digital tachograph 10 for enabling the operation of the crew regarding this special function. A specific example of the operation unit 80 is shown in FIG.

  The operation unit 80 shown in FIG. 2 includes three start buttons BT1A, BT1B, BT1C, an end button BT2 and a display area 27a arranged at positions where the crew can operate. The three start buttons BT1A, BT1B, and BT1C each have a function of inputting information indicating loading operation, unloading operation, and start of a break. The end button BT2 has a function of inputting information representing the end of the loading operation, the unloading operation, and the rest. The display area 27a has a function of displaying the maximum time display 27b and the elapsed time display 27c.

  The start button BT1A, BT1B, BT1C, and the end button BT2 are connected to switches (not shown) that are turned on and off in conjunction with the respective operations. Then, the signals of these switches are input to the CPU 11 via the SW input unit 22 of the digital tachograph 10. The display area 27 a is included in the display unit 27.

<Overview of communication operation>
The outline of the communication operation of the work management system 5 in the embodiment of the present invention is shown in FIG. The communication operation of FIG. 3 will be described below.

  The digital tachograph 10 mounted on the vehicle 75 can monitor work and the like performed by a crew while the vehicle 75 is stopped. For example, when the start button BT1A of the operation unit 80 is pressed by the crew, the communication control unit 11a of the digital tachograph 10 starts monitoring of the loading operation. Here, the communication control unit 11a starts measuring the elapsed time, and transmits a message MS11 indicating the start of the loading operation to the server 81 by wireless communication.

  When the server 81 receives the message MS11 from the digital tachograph 10, the server 81 transmits a message MS21 including work start information to the office PC 30. When receiving the message MS21 from the server 81, the office PC 30 displays work start information on the screen.

  On the other hand, before detecting the end of the started work or the like, if the elapsed time exceeds a predetermined maximum time, the communication control unit 11a of the digital tachograph 10 detects an abnormality, for example, Send a message MS12 representing "overtime notification" to the server 81. When the server 81 receives the message MS12, the server 81 transmits a message MS22 including, for example, "over work information" to the office PC 30. Furthermore, the server 81 transmits an electronic mail as the message MS23 to the office PC 30 and the portable terminal 82 of the administrator, respectively. About the information of the e-mail address showing the destination of the e-mail, it may be registered in advance in the database of the server 81, or may be registered in the transmission condition table TB1 of the digital tachograph 10. Also, instead of the e-mail, another information transmission method such as a short message may be used.

  When receiving the message MS22, the office PC 30 displays, for example, "over work information" and information indicating a delay in starting work on the screen to notify the administrator. The office PC 30 can also receive an e-mail including “over work information” and display the contents on the screen. Further, a predetermined manager can also receive an e-mail including “over work information” by his / her portable terminal 82 and confirm the contents.

  For example, if an accident such as a fall from a vehicle occurs during loading operation and the crew or worker can not move, the elapsed time is the maximum time before the digital tachograph 10 recognizes the completion of the operation. The message MS12 is transmitted upon detection of an excess, that is, an abnormally long. Therefore, the manager notices a change during loading work by the screen display of the office PC 30 or the display of the manager's portable terminal 82.

<Concrete system operation>
A specific operation example of the work management system 5 according to the embodiment of the present invention is shown in FIG. The operation shown in FIG. 4 will be described below.

  The communication control unit 11a of the digital tachograph (digital tachograph) 10 detects a signal by the user pressing one of the start buttons BT1A, BT1B, and BT1C in S11, and recognizes the start of the loading operation and the like.

  Then, the communication control unit 11a transmits the work start event information assigned to the pressed start buttons BT1A to BT1C as the message MS11 in S12. Also, at this point, the communication control unit 11a starts counting elapsed time.

  Further, the communication control unit 11a compares the current elapsed time with the maximum time held in the transmission condition table TB1, and identifies in S13 whether the work is over, that is, whether there is an abnormality. If there is an abnormality, the process proceeds to step S14. If there is no abnormality, the process proceeds to step S15.

  Further, the communication control unit 11a identifies the presence or absence of the work completion in S15. That is, when the signal by pressing the end button BT2 is detected, it is considered that the operation is completed, and the process proceeds to S16. Further, even when the end button BT2 is not operated, for example, when the start of movement of the vehicle is detected by monitoring of the vehicle speed signal, it is automatically recognized that the operation is ended.

  When the communication control unit 11a detects an abnormality in S13, the communication control unit 11a transmits, as a message MS12, work-over event information to the server 81 in S14. When the communication control unit 11a recognizes the end of work in S15, it resets the count of elapsed time, and transmits the event information on the end of work as the message MS13 to the server 81 in S16.

  On the other hand, when receiving the message MS11 transmitted from the digital tachograph 10, the server 81 processes this message in S21 to recognize the work start event, and transmits the message MS21 addressed to the office PC 30. When receiving the message MS21 transmitted from the server 81, the office PC 30 processes this message in S31 and displays information indicating the start of work on the screen.

  When the server 81 receives the message MS12 transmitted from the digital tachograph 10, the server 81 processes the message in S22 to recognize the over work event, and transmits the message MS22 to the office PC 30. Furthermore, the server 81 transmits an electronic mail as a message MS23 to the office PC 30 and the portable terminal 82 of the manager, respectively. When receiving the message MS22 transmitted from the server 81, the office PC 30 processes this message in S32 and displays information indicating work over, ie, an abnormality in the work, on the screen.

  When the server 81 receives the message MS13 transmitted from the digital tachograph 10, the server 81 processes this message in S23 to recognize the event of work completion, and transmits the message MS24 to the office PC 30. When receiving the message MS24 transmitted from the server 81, the office PC 30 processes this message in S33 and displays information indicating the end of work on the screen.

<Advantage of Work Management System 5>
In the work management system 5 shown in FIG. 1, the digital tachograph 10 monitors an abnormality in the elapsed time from the start to the end when loading work, unloading work, rest, etc. in a state where the vehicle is stopped. be able to. In addition, since the digital tachograph 10 transmits a message representing an event such as start, end, occurrence of abnormality, etc. to a device outside the vehicle, a manager or the like operating the office PC 30 can grasp the situation such as work in substantially real time. . In particular, if an unexpected event such as an accident or disaster occurs while working, even if the crew can not communicate the situation, the message will be sent automatically, so the administrator of the abnormality It can be understood by the side.

  In addition, even if the crew forgets to operate the end button BT2 at the end of the work, etc., the communication control unit 11a automatically recognizes it as the end of the work when it detects the start of movement of the vehicle (S15). Can prevent an erroneous “work over” message from reaching the administrator.

  In addition, as shown in FIG. 2, the crew can operate the operation monitoring function by displaying the maximum time display 27b or the elapsed time display 27c on the digital tachograph 10 side or displaying a message related to "over work". Can understand Therefore, it is possible to prevent the administrator side from receiving an erroneous "work over" message due to a simple operation error of the crew.

  Further, since the destination of the e-mail transmitted from the server 81 as the message MS23 is the manager's office PC 30 or the manager's portable terminal 82, there is no need for the crew to operate the e-mail. As a result, the operation of the crew can be reduced, and safety in vehicle operation can be ensured.

  In the work management system 5 shown in FIGS. 1 and 3, it is assumed that the server 81 is used, but the server 81 is omitted and the digital tachograph 10 is used as the office PC 30 and the portable terminal 82 of the administrator. Alternatively, the message may be sent directly.

  Further, for example, the end button BT2 illustrated in FIG. 2 may be omitted, and functions equivalent to the end button BT2 may be assigned to the start buttons BT1A, BT1B, and BT1C. For example, if the functions of the start buttons BT1A, BT1B, and BT1C are changed alternately to "start" and "end" for each operation, the special end button BT2 becomes unnecessary.
