Example Embodiment

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0022] See Figure 1-3 , The present invention provides a technical solution: a GPS dispatch monitoring terminal, including a terminal body 1, the terminal body 1 is installed in a vehicle, the front end of the terminal body 1 is installed with a monitoring display screen 2, the monitoring display screen 2. A plurality of alarm indicator lights 3 are arranged below the terminal body 1, a data transmission interface 4 is arranged on one side of the terminal body 1, a control circuit board 5 is installed inside the terminal body 1, and a control unit 6 is installed on the control circuit board 5. Sensor signal amplification unit 7, Beidou/GPS positioning unit 8, vehicle power management unit 9, dispatch matching unit 10, dispatch server 11, storage module 12, alarm module 13, and communication module 14. The sensor signal amplification unit 7 inputs The terminals are respectively connected to the vehicle CCD image sensor 15 and the vehicle speed sensor 16, the output terminal of the sensing signal amplifying unit 7 is connected to the control unit 6, and the control unit 6 is respectively connected to the Beidou/GPS positioning unit 8, the vehicle power management unit 9, and dispatch matching Unit 10, alarm module 13, the dispatch matching unit 10 is connected to the dispatch server 11, the control unit 6 is connected to the background dispatch monitoring center 17 through the communication module 14, the communication module adopts the TD-LTE communication network; wherein, the sensor signal The amplifying unit is used to amplify the collected sensor signals, the Beidou/GPS positioning unit is used to monitor the vehicle position in real time, the vehicle power management unit is used to detect the power of the vehicle, and the dispatch matching unit is used to dispatch And match idle vehicles.
[0023] In the present invention, the Beidou/GPS positioning unit 8 includes a low-power Beidou GPS positioning chip and an antenna; the Beidou/GPS positioning unit receives satellite signals through the antenna for positioning, and uses the Beidou GPS dual-mode mode for positioning by default. When it is too weak to obtain satellite signals, it will automatically switch to single mode for positioning, or you can set the single mode to obtain satellite signals. Beidou/GPS positioning unit 8 has a dual-system multi-frequency performance SOC chip, which can support two frequency points BDB1 and GPS L1. It has the characteristics of high integration, low power consumption, and small size. The module has high sensitivity and can work under weak signal conditions. It provides excellent acquisition and tracking sensitivity, maintains the continuity and reliability of receiver positioning, and supports single-system independent positioning and multi-system joint positioning.

[0025] Working principle: The use method of the present invention includes the following steps:
[0026] A. The vehicle CCD image sensor and the vehicle speed sensor respectively collect the image of the person in the vehicle and the vehicle speed signal, and the collected sensor signal is amplified by the sensor signal amplification unit and then transmitted to the control unit;
[0027] B. If the vehicle needs to be dispatched, first collect the vehicle status through sensors. If it is collected that there is no one in the vehicle and the vehicle is not running, then the Beidou/GPS positioning unit is used for vehicle positioning, and the collected position information is sent to the control unit;
[0028] C. At the same time, the control unit collects vehicle power supply information through the vehicle power management unit;
[0029] D. The dispatch server sends out vehicle usage requirements, and the dispatch matching unit automatically matches the number of idle vehicles and vehicle locations according to the vehicle usage requirements;
[0030] E. If the matched vehicle is scheduled to be used, the scheduling will be carried out, and if it is scheduled to be used, the search and matching will continue.
[0031] In summary, the present invention has simple working principle and high degree of intelligence, can realize real-time remote monitoring and scheduling of vehicles, can automatically match and schedule idle vehicles, and effectively improve the use efficiency of vehicles.
