  The CPU unit 50 includes a CPU (Central Processing Unit) 51, a storage unit 52, and an output unit 53.

  The CPU 51 is an arithmetic processing device that performs arithmetic processing. For example, Raspberry Pi 2 (Raspberry Pi 2) manufactured by Acorn (trademark) is used as the CPU 51 and the storage unit 52 described later. The CPU 51 calculates the vehicle speed and the rotational speed from the input vehicle speed information signal and the rotational speed information signal. This “calculation” includes calculation based on a calculation formula stored in the storage unit 52 and determination based on a table stored in the storage unit 52. In this table, for example, the vehicle speed and the rotational speed corresponding to the pulse interval of the vehicle speed information signal and the rotational speed information signal are stored in association with each other. The CPU 51 corresponds to the control unit.

  In addition, the CPU 51 performs writing to and reading from the storage unit 52 and output from the output unit 53. Specifically, as shown in FIG. 2, the CPU 51 associates the input position information and ETC information, the calculated vehicle speed and number of rotations, time information, the operation number and authentication ID described later, and stores them in the storage unit 52. The information is written and read from the storage unit 52 and output from the output unit 53.

  The storage unit 52 is a memory capable of writing and reading information. The storage unit 52 is an EEPROM, a RAM, a ROM, or the like.

  The output unit 53 is electrically connected to the antenna 21 as shown in FIG. Information output from the output unit 53 is transmitted to the outside via the antenna 21. In addition, although the antenna 21 is described as a transmission / reception antenna, the antenna that receives position information and the antenna that performs transmission may be provided in the vehicle 20 separately. The information transmitted from the output unit 53 is acquired by the server 12 through mobile communication or the Internet. Since mobile communication and the Internet are well known, detailed description is omitted.

  The server 12 is installed in a bus company office or the like, and is connected to a communication network such as a telephone line or the Internet. As shown in FIG. 2, the server 12 includes management software 65 and device memory 60.

  The device memory 60 stores a first correspondence table 61, a second correspondence table 62, and a third correspondence table 63.

  The first correspondence table 61 shows the correspondence between the vehicle 20 and the identification ID. The identification ID is individually assigned to the digital tachograph 11. Since one digital tachograph 11 is mounted on each vehicle 20, each vehicle 20 can be individually identified using an identification ID. The server 12 individually identifies the plurality of vehicles 20 owned by the bus company based on the correspondence relationship shown in the first correspondence table 61. The vehicle 20 and the identification ID are registered by the operator before the operation management system 10 is operated. Also, registration is updated when a new vehicle 20 is purchased or scrapped. In the example shown in FIG. 2, “000a” is the identification ID of “vehicle a”, “000b” is the identification ID of “vehicle b”, and “000c” is the identification ID of “vehicle c”. As the contents of “vehicle a”, “vehicle b”, and “vehicle c”, for example, the vehicle number, the vehicle type, the number of passengers, the purchase date, the scheduled vehicle inspection date, and the like are described. The identification ID corresponds to a second identification symbol.

  The second correspondence table 62 shows the correspondence between the driver's name and the authentication ID. The authentication ID is given to each card 13 individually. Since one card 13 is provided to each driver, each driver can be individually identified using an authentication ID. The server 12 individually identifies a plurality of drivers working at the bus company based on the correspondence shown in the second correspondence table 62. The name and the authentication ID are registered by the operator before the operation management system 10 is operated. In addition, registration is renewed at the time of joining the company or leaving the company. In the example shown in FIG. “AAAA” is an authentication ID of “Mr. Taro Yamada”, “BBBB” is an authentication ID of “Mr. Jiro Tanaka”, and “CCCC” is an authentication ID of “Mr. Saburo Suzuki”. The authentication ID corresponds to a first identification symbol.

  The third correspondence table 63 shows the correspondence between the operation number and the operation schedule. The operation schedule is composed of information such as destination, departure time, arrival time, route, planned number of passengers, rest place, and the like. The operation number is a number assigned individually to each operation schedule. The server 12 individually identifies each operation schedule according to the correspondence shown in the third correspondence table 63. The operation number and the operation schedule are registered at any time by the operator. The operation number corresponds to the operation schedule information. In addition, the example of operation schedule information is not restricted to the above-mentioned operation number. The operation schedule information may be information that can identify the operation schedule.

  The management software 65 is software that performs operation management of the vehicle 20 and management of working hours of employees (drivers).

  The management software 65 determines which vehicle 20 is used for which operation schedule from position information, vehicle speed information, rotation speed information, identification ID, operation number, time information, and ETC information, which are information transmitted by the digital tachograph 11. The operation management is performed such as whether the operation route is as scheduled, whether the operation time is not significantly deviated from the operation schedule, or whether the operation route is resting at a scheduled rest area (parking area).

  Also, the management software 65 calculates which driver has been driving which vehicle 20 for how long from the authentication ID, identification ID, operation number, and time information. Further, the total operation time in a predetermined period (for example, one month) is calculated. The calculated total operation time is used for salary calculation, for example. The management software 65 corresponds to a calculation unit.

  In the following, referring to FIG. 2, two drivers, Mr. Taro Yamada, who has a card 13A with an authentication ID “AAAA”, and Mr. Jiro Tanaka, who has a card 13B with an authentication ID “BBBB”, have an identification ID. The operation of the operation management system 10 will be described by taking as an example a case where the vehicle 20 (vehicle a) with “000a” is boarded and engaged in the operation scheduled for operation with the operation number “001”.

  First, the operator assigns the operation number “001” to the operation schedule and registers it in the server 12. Before getting on the vehicle 20, the two drivers download the operation number “001” that they plan to engage in their own cards 13A and 13B. That is, the operation number “001” is stored in the terminal memory 31 of the cards 13A and 13B.

  Mr. Taro Yamada, the driver who first drives the vehicle 20, holds his card 13 </ b> A over the NFC communication unit 71 of the digital tachograph 11.

It is transmitted to the digital tachograph 11. The CPU 51 of the digital tachograph 11 stores the acquired authentication ID “AAAA” and operation number “001” in the storage unit 52.

  Next, the operation when the vehicle 20 is traveling will be described. The digital tachograph 11 calculates the vehicle speed from the input vehicle speed information, and calculates the rotation speed from the input rotation speed information. The digital tachograph 11 uses the calculated vehicle speed and rotational speed, the position information input from the position information input unit 45, the ETC information input from the ETC information input unit 46, and the time information acquired from the clock module 48 as described above. The authentication ID “AAAA” and the operation number “001” are associated with each other and stored in the storage unit 52. Further, the CPU 51 of the digital tachograph 11 associates the vehicle speed, the number of revolutions, the position information, the ETC information, the time information, the authentication ID “AAAA”, the operation number “001”, and the identification ID “000a” assigned to itself. Output from the output unit 53. The output information (operation information) is transmitted from the antenna 21 to the outside of the vehicle. This transmitted information is input to the server 12 via the Internet or the like.

  The server 12 that has acquired the operation information from the vehicle 20 is engaged in the operation schedule specified by the operation number “001” for the vehicle 20 (vehicle a) with the identification ID “000a”, and the current driver is authenticated. Confirm that it is Mr. Taro Yamada identified by the ID “AAAA”. The information is stored in the device memory 60. The server 12 confirms that the vehicle 20 is resting at the planned resting place through the planned route.

  When the driver changes, Mr. Jiro Tanaka, who performs the next driving, holds his card 13B with the authentication ID “BBBB” over the NFC communication unit 71 of the digital tachograph 11 before driving. By this operation, close proximity wireless communication is performed between the second communication unit 32 of the card 13B and the NFC communication unit 71 of the digital tachograph 11, and the authentication ID “BBBB” of the card 13B and the downloaded operation number “001” are stored. To the digital tachograph 11. The digital tachograph 11 stores the acquired authentication ID “BBBB” and operation number “001” in the storage unit 52.

  Similarly to the above, the CPU 51 of the digital tachograph 11 corresponds to the vehicle speed, the rotational speed, the position information, the ETC information, the authentication ID “BBBB”, the operation number “001”, and the identification ID “000a” assigned to itself. In addition, the data is stored in the storage unit 52 and output from the output unit 53.

  The server 12 confirms from the operation information output by the digital tachograph 11 that the driver has changed to Mr. Jiro Tanaka identified by the authentication ID “BBBB”, the time when the driver has changed, and the like. The information is stored in the device memory 60. The server 12 calculates the driving time for each authentication ID, that is, for each driver, from the stored driving change time and the like. The calculation of the operation time is performed, for example, on a monthly basis. The total value of the calculated operation time is used for salary calculation and the like.

  As described above, when the operation management system 10 of the present embodiment is used, the vehicle 20 such as which vehicle 20 is engaged in which operation schedule, who is driving, and whether the vehicle is operating according to the operation route. Can be operated.

  Further, as described above, when the operation management system 10 of the present embodiment is used, salary calculation can be easily performed without receiving a follow-up report from the driver regarding the driving time.

  In the above-described embodiment, an example in which the operation management system 10 is used for bus operation management has been described. However, the operation management system 10 is not limited to bus operation management. For example, the operation management system 10 of the present invention can be used for a route delivery vehicle that delivers a product through a predetermined route. That is, the operation management system 10 of the present invention can be used for vehicles that are required to operate as scheduled.
