Vehicle conveyance system and working method thereof based on GPS and GIS

[0024] Embodiment 1: A vehicle transportation system based on GPS and GIS (see Figure 1), which is characterized in that it is composed of a vehicle-mounted GPS receiver, a communication phone handle, a display screen, a communication controller, a communication antenna, a data service center, Customer monitoring center, Internet server, electronic map, large LCD screen; among them, the on-board GPS receiver is connected to the GPS positioning satellite that sends navigation and positioning signals according to the satellite signal on the one hand, and connected to the communication controller on the other hand; communication phone The handle and the display screen are respectively connected to the communication controller; the communication controller is connected to the communication antenna of the vehicle terminal; the communication antenna of the vehicle terminal is connected to the communication antenna of the command center through the GSM/GPRS wireless data transmission network; the communication antenna of the command center It is connected to the data service center and the customer monitoring center for overall scheduling and management; the data service center is connected to the customer monitoring center, the Internet server, and the electronic map used to display the real-time situation and location of the vehicle; the electronic map is connected to the LCD Screen; Internet server is connected to the Internet.

[0025] The above-mentioned communication antenna (see Figure 1) is composed of the communication antenna of the vehicle terminal and the vehicle antenna of the command center. The communication antenna of the vehicle terminal is connected to the communication antenna of the command center through the GSM/GPRS wireless data transmission network. .

[0026] The above-mentioned electronic map (see Figure 1) is based on the GIS geographic information system, based on geospatial data, and in accordance with the association of geographic features, links various data at different levels to form a real world model and provide multiple A computer technology system for spatial and dynamic geographic information.

[0027] A working method of the above-mentioned GPS and GIS-based vehicle transportation system is characterized in that it includes the following working steps:

[0028] (1) Obtain GPS positioning information: The vehicle-mounted GPS receiver in the transport vehicle receives and obtains information related to the vehicle from the GPS positioning satellite;

[0029] (2) Sending information to the command center: The communication antenna of the vehicle terminal sends the acquired GPS positioning information and related information of the vehicle to the data service center through the GSM/GPRS wireless data transmission network in a timed or fixed distance manner. ;

[0030] (3) The command center sends dispatching instructions and information: The customer monitoring center can grasp all information related to driving at any time according to the GPS positioning information received by the data service center and the known electronic map data of the GIS geographic information system, and send it to the vehicle terminal Send dispatch instructions, and at the same time, the data service center sends information related to the vehicle to the vehicle-mounted terminal;

[0031] (4) Navigation vehicle transportation: The vehicle-mounted terminal receives the above-mentioned various information from the command center through the communication antenna, and displays the operating status information of the vehicle and the received data from the data service center and the customer monitoring center to the vehicle-mounted terminal through the display screen. Various types of information, the driver uses the information to drive and transport the vehicle to realize vehicle navigation;

[0032] (5) Communication between the driver and the customer monitoring center: The driver communicates with the telephone handle or data transmission, and communicates with the customer monitoring center, and cooperates with the overall scheduling and management of the customer monitoring center to realize real-time communication and interaction between the two;

[0033] (6) Electronic map displayed by the command center: the electronic map of the command center, based on the known GIS geographic information system data and the received GPS vehicle positioning information, comprehensively generates an electronic map, and displays it on the large LCD screen;

[0034] (7) Customer Interner query: The customer connects to the Interner server of the command center through the Internet or SMS platform, and from the data service center connected to the Interner server, understands the real-time status and related information of the vehicle loaded with the customer’s cargo information.

[0035] In the above-mentioned step (1), the GPS vehicle-mounted terminal receiving and acquiring information related to the vehicle includes directly obtained information and information obtained through processing. The directly obtained information may include the positioning information and precise timing of the vehicle, such as Longitude, latitude, altitude, time, the processed information includes the vehicle's running speed, direction of movement, etc.

[0036] The relevant information of the vehicle mentioned in the above-mentioned step (2) sending information includes general information, status information, business information, alarm information, etc. of the vehicle. The alarm information includes speeding alarm, route deviation alarm, and emergency alarm. Wait.

[0037]The information sent by the command center in the step (3) mentioned above includes general information such as road condition information and weather forecast.
