[0024] In the present invention, the sensing signal amplifying unit includes a first operational amplifier 18 and a second operational amplifier 19. The positive input of the first operational amplifier 18 is connected to the negative electrode of the diode A1b, and the negative input of the first operational amplifier 18 is respectively connected to a resistor. One end of B2a, one end of resistor A1a and one end of capacitor 20. The other end of resistor B2a is connected to the anode of diode A1b. Both ends of said diode A1b are signal receiving ends. The other end of resistor A1a and the other end of capacitor 20 are respectively connected to first operational amplifier 18. A resistor C3a is connected between the output terminal of the first operational amplifier 18 and the negative input terminal of the second operational amplifier 19, the positive input terminal of the second operational amplifier 19 is grounded, and the negative input terminal of the second operational amplifier 19 is connected to the A resistor D4a is connected between the output terminals, the output terminal of the second operational amplifier 19 is connected to the anode of the diode B2b, and the cathode of the diode B2b is the signal output terminal. The sensing signal amplifying unit adopted in the present invention adopts two operational amplifiers, which can amplify the signal step by step, thereby decomposing the work load, thereby improving the transmission efficiency and quality of the sensing signal, and further improving the scheduling efficiency.

[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.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. And variations, the scope of the present invention is defined by the appended claims and their equivalents.
