Description

  The present invention relates to an operation management system that manages the operation of a plurality of vehicles.

  Conventionally, an operation management system has been proposed that collects and analyzes travel data acquired by an on-vehicle device mounted on a vehicle at a management center (for example, an office PC) and manages the operation of the vehicle. Yes.

  For example, one of the conventional operation management systems (hereinafter referred to as “conventional system”) stores vehicle travel data in a memory card provided in the vehicle-mounted device for a predetermined period (for example, after the vehicle leaves the sales office, the vehicle returns to the sales office) The travel data recorded on the memory card is read by a terminal installed at the sales office, and the travel trajectory of the vehicle is displayed on a map in the display. For example, see Patent Document 1.)

FIG. 1 is a block diagram showing a configuration of an operation management system according to an embodiment of the present invention. FIG. 2 is a flowchart showing an example of an operation procedure of the operation management system shown in FIG.

  Hereinafter, an operation management system (hereinafter referred to as “operation management system 1”) according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the operation management system 1 manages the operation of a vehicle, and is mounted on each of a plurality of vehicles to be managed (in this example, mounted on three vehicles). Three in-vehicle devices 100) and an office PC 200 as a management device.

  Each of the vehicle-mounted devices 100 has a function of acquiring travel data including information in which the position of the vehicle on which the vehicle-mounted device 100 is mounted and time are associated with each other. The office PC 200 receives the travel data of each of the plurality of vehicles from the in-vehicle device 100, extracts specific data satisfying a specific condition from each of the travel data, and based on the specific data, each travel locus of the plurality of vehicles. It has a function to display on the map while relating them to each other.

  Specifically, the vehicle-mounted device 100 includes a CPU 101, a GPS receiving unit 102, a speed I / F 103, various information input I / Fs 104, a recording unit 105, a power supply unit 106, a communication unit 107, a memory 108, an RTC (clock) 109, and A card I / F 110 is included.

  The CPU 101 controls the entire vehicle-mounted device 100. The GPS receiving unit 102 receives a signal from a PS satellite and inputs current position information to the CPU 101. The speed I / F 103 inputs vehicle speed information corresponding to a speed pulse output from a vehicle speed sensor mounted on the vehicle to the CPU 101. The various information input I / F 104 inputs various types of information such as an in-vehicle camera image to the CPU 101. The recording unit 105 records travel data and the like calculated by the CPU 101. The power supply unit 106 supplies power to each unit of the vehicle-mounted device 100.

  The communication unit 107 transmits and receives various types of information to and from the office PC 200 via the antenna 107a through a wide area communication network 901 such as a wireless communication line (for example, a 3G line) and a packet communication network 902 such as the Internet. The memory 108 includes a ROM that stores an operation program executed by the CPU 101 and a RAM that provides a working memory area. The RTC (clock) 109 measures the current time and inputs a signal corresponding to the time to the CPU 101. The card I / F 110 writes data to the memory card (information recording medium) 300 or reads data from the memory card 300.

  On the other hand, the office PC 200 is configured by a general-purpose personal computer (PC), and includes a CPU 201, a communication unit 202, a display unit 203, a storage unit 204, a map database 205, an input unit 206, an operation unit 207, and an output unit 208. Have.

  The CPU 201 controls the entire office PC 200. The communication unit 202 communicates with the vehicle-mounted device 100 via the wide area communication network 901 and the packet communication network 902. The display unit (display) 33 displays an operation management screen and the like. The storage unit 204 stores an operation program executed by the CPU 201, travel data of each vehicle, and the like. Map information is registered in the map database 205 (map information storage unit).

  The input unit 206 is configured so that the memory card 300 can be inserted, and the traveling data stored in the memory card 300 is input. The operation unit 207 includes a keyboard and a mouse. A manager or the like of the operation management system 1 gives an instruction regarding operation management to the CPU 201 via the operation unit 207. The output unit 208 outputs various data to an external device.

  Next, the operation of the operation management system 1 will be described.

  When a vehicle equipped with the vehicle-mounted device 100 starts traveling, traveling data of the vehicle is transmitted from the vehicle-mounted device 100 to the office PC 200 every moment. The travel data includes data that can identify the vehicle on which the vehicle-mounted device 100 is mounted, and data that associates the position and time of the vehicle.

  The office PC 200 receives the travel data of each vehicle from each on-vehicle device 100 and stores the received travel data in the storage unit 204. The office PC 200 uses the operation unit 207 to specify what conditions the traveling data is to be analyzed and displayed (specific data to be extracted from the traveling data) based on the conditions. Specific data that satisfies the specified conditions is extracted from the travel data of the vehicle, and the travel trajectories of the plurality of vehicles are displayed on the map while being associated with each other.

  Specifically, the CPU 201 of the office PC 200 executes the processing shown in the flowchart of FIG. 2 and displays a travel locus corresponding to the administrator's instruction on the display unit 203.

  Specifically, when the process of FIG. 2 is started, the CPU 201 determines whether or not a range (display area) on the map to be displayed is designated in step S1. The display area is specified by, for example, specifying a radius centered on a predetermined position and specifying a prefectural / city / town area. When the display area is specified, the CPU 201 determines “Yes”, proceeds to step S2, and extracts travel data corresponding to the display area. Thereafter, the CPU 201 proceeds to step S3. On the other hand, if the display range is not designated, the CPU 201 determines “No” and proceeds directly to step S3.

  Next, in step S3, the CPU 201 determines whether a vehicle to be displayed (display vehicle) is designated. The designation of the display vehicle is performed by designation of an individual identification number of the vehicle, for example. When the display vehicle is designated, the CPU 201 determines “Yes”, proceeds to step S4, and extracts travel data corresponding to the display vehicle. Thereafter, the CPU 201 proceeds to step S5. On the other hand, if the display vehicle is not designated, the CPU 201 determines “No” and proceeds directly to step S5.

  Next, in step S5, the CPU 201 determines whether a time interval (display timing) to be displayed has been specified. The display timing is specified by, for example, specifying a time interval for updating the display of the display unit 203. If the display timing is specified, the CPU 201 determines “Yes”, proceeds to step S6, and extracts travel data corresponding to the display timing. Thereafter, the CPU 201 proceeds to step S7. On the other hand, if the display timing is not specified, the CPU 201 determines “No” and proceeds directly to step S7.

  Next, in step S7, the CPU 201 calculates a travel locus to be displayed on the display unit 203 based on the extracted travel data, and analyzes the relevance (correlation, etc.) of the travel tracks of a plurality of vehicles to be displayed. Thereafter, in step S8, the CPU 201 causes the display unit 203 to display on the map the display of the travel trajectory of the display target vehicle and the relevance of the travel trajectories.

  As the above-described relevance of the travel locus, for example, when performing a real-time analysis via the communication networks 901 and 902, a travel locus in which the moving speeds of a plurality of vehicles are reduced at a specific position is displayed. , Displaying that there is a traffic jam at that position. Furthermore, for example, when performing a subsequent analysis using the memory card 300, it is possible to grasp the movements of a plurality of vehicles in a specific area and display that the delivery work can be improved.

  In the case where the travel locus is displayed as described above, when an instruction to display the operation detail information is given, the CPU 201 determines “Yes” in step S9 and proceeds to step S10. In step S10, the CPU 201 displays the operation detail information together with the travel locus. Specifically, for example, when the mouse cursor is set on the vehicle icon on the travel locus, the CPU 201 designates the operation detail information to be displayed. It is determined that has been made. Then, the CPU 201 pops up and displays operation detailed information (for example, time, travel speed, and on-vehicle camera image) around the vehicle icon.

  According to the operation management system having the above configuration, it is possible to easily grasp the relevance of each traveling locus of a plurality of vehicles on a map. Furthermore, since the travel locus can be displayed by focusing on specific conditions, the amount of data to be displayed can be reduced as compared with the case where all data is displayed. Therefore, the operation management system of this configuration can display the traveling trajectories of a plurality of vehicles as simply as possible while considering the relevance of each other.

  The present invention is not limited to the above embodiments, and various modifications can be adopted within the scope of the present invention.
