The output unit 57 can output various data to a printer or the like and print it.

  FIG. 2 is a diagram showing data used by the vehicle-mounted device 10, the center 30, and the user PC 50, respectively. The vehicle-mounted device 10 acquires operation data such as the total traveling distance of the vehicle 3, the maximum speed during traveling, ignition on / off (ON / OFF) information, GPS position data, loading weight, fuel amount, and the like, and via the network 70. To the center 30.

  The center 30 stores, in the storage 37, a database 37z including master information 61 and travel history information 62. The master information 61 includes a vehicle master 61A, an in-vehicle device master 61B, and a customer master 61C. The vehicle master 61A includes a vehicle code, production information, and sales information (see FIG. 4) for each vehicle. The vehicle-mounted device master 61B includes a vehicle-mounted device serial number and device information for each vehicle-mounted device. The customer master 61C includes a customer name and other customer information for each customer. The center 30 stores the stock management table 100 in the storage 37 separately from the database 37z.

  FIG. 3 is a diagram showing registered contents of the inventory management table 100. The inventory management table 100 is stored in the storage 37 of the center 30. When the vehicle 3 is in the stock area 90 (see FIG. 4) based on the data transmitted from the vehicle-mounted device 10 or the data input via the operation unit 36, the center 30 additionally records the stock management table 100.・ Manage inventory such as updating. Further, the center 30 may create the inventory management table 100 for all the inventory areas (without designation), or may create the inventory management table 100 for the designated inventory area.

  The inventory management table 100 registers data of the type of the stock area (location type), the position of the stock area (location), the vehicle code, the date of entry, the date of exit, and the number of stays for each vehicle. The length of stay is the number of days obtained by subtracting the date of entry from the date of exit. In addition, in addition to the date and time when the vehicle actually leaves, the scheduled date and time (for example, delivery date) may be registered as the retrieval date and time. When the delivery date and time is earlier than the current date and time, the user can understand that the delivery date and time indicates the scheduled date and time. In the case of the scheduled date and time, the display mode of the leaving date and time may be changed (for example, the font is changed diagonally) to make it easier to understand visually. This scheduled date and time can also be used as vehicle identification information, similar to the scheduled date and time described later.

  FIG. 3A shows the inventory management table 100 when the inventory area is designated as yard. In FIG. 3A, the type of the stock area is a yard, and five yards (Yard1 to Yard5) are shown. For example, in the third row of the inventory management table 100, the type of the inventory area: Yard (yard), the location of the inventory area: Yard3, the vehicle code: 0003, the date of entry: September 23, the date of exit: September 28. , Days of stay: 5 are registered.

  Whether or not the vehicle is in stock can be determined by comparing the current date and time and the leaving date and time. Further, for example, by changing the display mode (character color, background color, etc.) of the data (stock record) for each vehicle registered in the stock management table 100, the administrator of the center 30 or the user of the PC 50 can change the display mode for each vehicle. You may make it possible to visually recognize the stock status (during storage, leaving, etc.).

  Further, the center 30 may input and register the date and time at which the stock status ends, that is, the scheduled date and time of leaving the vehicle, instead of the vehicle code, as the vehicle identification information. The scheduled date and time may be included in data transmitted from the vehicle-mounted device 10 to the center 30, or may be input by an administrator of the center 30 when the stay deadline or the like is determined in advance by the delivery date or the like. When the date and time when the ignition is switched from ignition on to ignition off is later than the scheduled date and time, the center 30 records information indicating that it is not in the stock state in the stock management table 100. The information indicating that the item is not in the stock state may be recorded by rewriting the characters of the scheduled date and time in the inventory management table 100 to characters such as “elapsed”, or may be recorded by adding an item to the inventory management table. Is also good. Further, the information indicating the non-stock status (the end of the stock status) may be recorded in the storage 37 in a file different from the stock management table. As an example of the vehicle being out of stock, the vehicle may be in a service state in which the vehicle has been delivered. Further, as described above, the inventory record of the vehicle that is no longer in stock may be displayed in a display mode different from the inventory record of the vehicle that is in stock.

  In this way, for example, by recording the delivery date and time of the vehicle as the scheduled date and time when the inventory status ends, if the possibility that the vehicle has been delivered is high, the information recorded in the inventory management table 100 is changed to the inventory status. Can be reliably updated to a state that is not in stock.

  FIG. 3B shows the inventory management table 100 when no inventory area is specified. The stock management table 100 shows stock records of vehicles in all stock areas. Here, a parking lot, a yard, and the like of a factory are shown as stock areas. Note that when the retrieval date is unregistered (-), that is, blank (the second row of the inventory management table in FIG. 3B), it indicates that the vehicle has not exited and stays in the inventory area. Further, when the delivery date is earlier than the current date and time (the third line of the inventory management table in FIG. 3B), the delivery date and time indicate that the delivery date is the scheduled date and time. If the vehicle code is registered as date and time information, it indicates that the vehicle code is a scheduled date and time (not shown).

  The operation of the management system 5 having the above configuration will be described. FIG. 4 is a diagram showing registration of master information 61 performed in the flow from production of vehicle 3 to delivery. In the factory 150, work of assembling D1 of the vehicle 3 and attaching D2 of the vehicle-mounted device 10 are performed. When these operations are completed, production information is input to the master information 61. The production information includes a vehicle chassis number, a vehicle-mounted device serial number, a shipping date, and production information. By registering the production information in the master information 61, the vehicle 3 registered in the vehicle master 61A and the vehicle-mounted device 10 registered in the vehicle-mounted device master 61B are linked. When the production information is input, the inventory management of the vehicle is started. The vehicle 3 produced in the factory 150 is waiting to be shipped in the factory 150, and then shipped (D3).

  The vehicle 3 shipped from the factory 150 moves to the yard 91 and waits until a sales destination is determined (D4). When the sales destination is determined, sales information is input to the master information 61 of the vehicle 3 that has entered the yard 91. The sales information includes a vehicle chassis number, a vehicle-mounted device serial number, a customer name / dealer name, a delivery date, and sales information. Thereby, in the master information 61, the vehicle 3 registered in the vehicle master 61A, the vehicle-mounted device 10 registered in the vehicle-mounted device master 61B, and the customer registered in the customer master 61C are linked. The vehicle 3 is assumed to belong to the temporary company until the vehicle 3 registered in the vehicle master 61A and the vehicle-mounted device 10 registered in the vehicle-mounted device master 61B are linked with the customer registered in the customer master 61C. You.

  When the sales information is input, the exterior component is attached to the vehicle 3 by the body maker 92 (D5). The vehicle 3 to which the exterior components are attached moves to the dealer's parking lot 93 and waits for delivery (D6). Thereafter, the vehicle 3 is delivered to the sales destination (D7).

  FIG. 5 is a graph showing the stock quantity of vehicles for each stock area where vehicles are placed. After the vehicle-mounted device 10 is assembled to the vehicle 3, the center 30 specifies the stock area where each vehicle 3 is located based on the GPS position information of the vehicle 3 transmitted from the vehicle-mounted device 10. The center 30 manages the stock quantity of the vehicle 3 for each stock area where the vehicle 3 is placed. Here, the case where the stock area where the vehicle is placed is a parking lot of a factory, a yard, a body maker, and a dealer is shown. Note that, instead of the stock quantity of the vehicle, the stay ratio indicating the period of being placed in each stock area may be indicated together with the stock quantity or separately from the stock quantity.

  FIG. 5A is a pie chart showing, at a certain point in time, the stock quantity of the vehicle in each stock area of the parking lot of the factory, the yard, the body maker and the dealer. In the factory 150, 12 vehicles are staying. In the yard 91, 15 vehicles are staying. Nine vehicles are staying at the body maker 92. In the parking lot 93 of the dealer, three vehicles are staying.

  FIG. 5B is a bar graph showing the number of vehicles in stock in each inventory area of a factory, a yard, a body maker, and a parking lot of a dealer by month. The vertical axis indicates the number of vehicles in stock, and the horizontal axis indicates the monthly unit. You can see the change in the number of stocks in the parking lots of factories, yards, body makers and dealers. For example, in the factory 150, the stock of vehicles was 240 in July, but the stock has been reduced to 100 in November. In the yard, the stock of vehicles was 260 in July, but the stock was reduced to 110 in November. In the bodymakers, the stock of vehicles was 200 in July, but the stock was reduced to 80 in November. In the parking lot 93 of the dealer, the stock of vehicles was 190 in July, but the stock was reduced to 40 in November.

  In this way, by graphing the number of stays for each stock area where vehicles are placed, it becomes easier for the manager of the center 30 to know where the stock of vehicles is large. Further, the manager can grasp the change of the stock of the vehicle in each stock area.

  FIG. 6 is a flowchart showing an ignition-off event processing procedure. The CPU 31 of the center 30 receives the ignition on / off information of the vehicle 3 transmitted from the vehicle-mounted device 10. This process is executed as an event process by the CPU 31 when the CPU 31 of the center 30 receives the ignition-off information of the vehicle 3 transmitted from the vehicle-mounted device 10. The CPU 31 receives the GPS position data of the vehicle 3 transmitted from the vehicle-mounted device 10 via the communication unit 32. The GPS position data includes time data.

  When receiving the ignition-off information from the vehicle-mounted device 10, the CPU 31 determines whether or not the reception date and time of the received ignition-off is after the delivery date (S1). If it is after the delivery date, the CPU 31 determines that the delivery has been completed, and changes the state of the vehicle included in the vehicle master 61A to the service state (S2). The vehicle 3 in the service state is not counted as inventory. Thereafter, the CPU 31 ends the present processing.

  On the other hand, if the reception date and time of the ignition-off is before the delivery date in step S1, the CPU 31 determines whether or not the vehicle 3 is in the stock area 90 (S3). Here, the stock area 90 includes the factory, the yard, the body maker, and the parking lot of the dealer, as described above. When the vehicle 3 is not in the stock area 90, the CPU 31 determines that the vehicle 3 is not a target (S4), and ends this processing. Note that, here, the step in which the CPU 31 does not perform any processing is also described as a step processing so that the comparison with processing (S2, S6, or the like) corresponding to other conditions is clearly and easily understood.

  If the vehicle 3 is in the stock area 90 in step S3, the CPU 31 determines whether the vehicle 3 has not arrived at the stock area 90 for the first time (S5). When the vehicle 3 arrives at the stock area for the first time, the CPU 31 starts stock recording in the stock management table 100 at the stock position (GPS position) at the time when the ignition is turned off (S6). At this time, the CPU 31 updates the entry date and time of the inventory management table 100 by inputting the date and time when the ignition is turned off. Thereafter, the CPU 31 ends this processing.

  If the vehicle 3 has arrived at the stock area 90 for the second time or later in step S5, the CPU 31 determines whether the stock location of the vehicle 3 is different from the previous stock location (S7). That is, the CPU 31 determines whether or not it is the same as the place where the vehicle 3 stopped last time. If it is the same as the previous inventory location, the CPU 31 restarts inventory recording (S8). On the other hand, if it is different from the previous stock location, the CPU 31 newly starts stock recording at the stock position at the time of ignition off (S9). After the processing in steps S8 and S9, the CPU 31 ends the present processing.

  FIG. 7 is a flowchart showing an ignition-on event processing procedure. When receiving the ignition-on information from the vehicle-mounted device 10, the CPU 31 determines whether or not the vehicle 3 is in the stock area 90 (S11). When the vehicle 3 is not in the stock area 90, the CPU 31 determines that the vehicle 3 is not a target and does nothing (S12), and ends this processing.

  If the vehicle 3 is in the stock area 90 in step S11, the CPU 31 determines whether or not the vehicle 3 arrives at the stock area 90 for the first time (S13). When the vehicle 3 arrives at the stock area 90 for the first time, the CPU 31 determines that the vehicle 3 is traveling toward the stop position in the stock area 90, does nothing (S14), and ends this processing.

  If the vehicle 3 has arrived at the stock area for the second time or later in step S13, the CPU 31 determines whether the stock location of the vehicle 3 is the same as the previous stock location (S15). That is, the CPU 31 determines whether or not it is the same as the place where the vehicle 3 stopped last time.

  If it is different from the previous inventory location, the CPU 31 sets an error flag on the previous inventory record and invalidates this inventory record (S16). When an error occurs in the inventory record, for example, the display mode (flashing display or the like) of the corresponding data in the inventory management table 100 is changed. An example of a case where an error occurs in the inventory record is a case where the vehicle moves without using a ferry or the like from the time when the ignition is turned off to the time when the ignition is turned on. Thereafter, the CPU 31 ends this processing.

  If it is the same as the previous stock location in step S15, the CPU 31 inputs and updates the date and time when the ignition was turned on to the stocking date and time of the stock management table 100 as the end of the stock record (S17). Thereafter, the CPU 31 ends this processing.

  As described above, the event processing of the ignition off or the ignition on shown in FIGS. 6 and 7 is executed by the CPU 31 of the center 30 so that the inventory management table 100 indicating the stock status of the vehicle in the stock area 90 is automatically recorded.・ Updated.

  FIG. 8 is a sequence diagram illustrating an operation procedure of the management system 5.

The center 30 displays the created stock quantity graphs 120 and 130 on the display unit 33 (T17). Thereafter, the same operation is performed.

  As described above, in the management system 5 of the present embodiment, the number of vehicles that are in the inventory area and that are turned off is defined as the vehicle inventory number. The vehicle-mounted device 10 transmits the GPS position data and the ignition-off information of the vehicle 3 to the center 30. The center 30 records the entry of the vehicle 3 by receiving the GPS position data and the ignition-off information transmitted from the vehicle-mounted device 10. Therefore, the management system 5 can easily manage the stock status of the vehicle. In addition, the center manager can count the number of vehicles in stock without performing manual input when performing warehouse management. Thereby, the trouble of the input operation can be saved. In addition, the manager of the center 30 can grasp detailed information such as the number of stocked vehicles in each stock area 90 where the vehicles 3 are placed and the number of days of staying of each vehicle.

  As described above, the management system can determine whether or not the vehicle is in stock based on the position information and the operation information of the vehicle input from the vehicle-mounted device. Therefore, the user can recognize whether or not each vehicle is in stock by referring to the record of the management device.

  Also, the center 30 receives the GPS position data and the ignition on information transmitted from the vehicle-mounted device 10, and when the vehicle is switched from the non-operation state to the operation state in the stock area, the information indicating that the vehicle is not in the stock state. Record Therefore, the fact that the vehicle has become out of stock can be automatically recorded. Further, the manager of the center 30 can total the stock quantity of the vehicle without performing manual input when performing the outgoing management. Thereby, the trouble of the input operation can be saved.

  As described above, even when the vehicle changes from the stock state to a state other than the stock state such as delivery, the transition of the state is automatically recorded in the stock management table stored in the storage 37. It is possible to prevent a vehicle that has become a vehicle other than the vehicle from being continuously recorded as a stock status due to forgetting to input.

  In addition, the center 30 can input the scheduled date and time when the stock status ends, instead of the vehicle code, as the vehicle identification information. The scheduled date and time may be included in data transmitted from the vehicle-mounted device 10 to the center 30, or may be input by an administrator of the center 30 when a stay deadline or the like is determined in advance. When the date and time when the ignition is switched from ignition on to ignition off is after the scheduled date and time, the center 30 records information indicating that it is not in the stock state in the stock management table 100 stored in the storage 37 or another file. .

  In this way, for example, by recording the delivery date and time of the vehicle as the scheduled date and time when the stock status ends, the information recorded in the storage 37 can be changed from the stock status to the stock when the possibility that the vehicle has been delivered is high. It can be surely updated to no state.

  Further, the manager of the center 30 and the user of the PC 50 can display the stock quantity of the vehicle 3 in each stock area in a pie chart on the display unit 33 of the center 30 and the display unit 53 of the user PC 50, respectively. In addition, the manager of the center 30 and the user of the PC 50 can see the number of vehicles in each stock area displayed on the display unit 33 of the center 30 and the display unit 53 of the PC 50 in a bar graph by month. Therefore, the manager of the center 30 and the user of the PC 50 can visually grasp the stock quantity of the vehicle in each stock area. In addition, the administrator of the center 30 and the user of the PC 50 can know where the vehicle inventory is large. Further, the manager of the center 30 and the user of the PC 50 can grasp the change of the stock of the vehicle in each place.

  In addition, the number of days of stay, the stock area, and the like can be recorded for each vehicle, and detailed information on stock management can be obtained. For example, if there is a large number of vehicles in the factory, it can be understood that there are many vehicles in the process of being assembled (work in progress), and the center manager should review the process and improve the production plan by reducing the number of vehicles. Can also.

  Further, the manager of the center and the user of the PC can check the change in the number of stocks for each stock area and take appropriate measures according to the time. For example, if the number of stocks increases in July, measures that contribute to the reduction of the number of stocks can be taken, such as reducing the number of production units or conducting sales promotion activities in advance.

  As described above, the user can confirm the totaling result of the stock status of a plurality of vehicles using the display device. Therefore, even when a large number of vehicles are to be managed, the stock status of these vehicles is displayed in an aggregated form, so that the user can easily grasp the stock status.
