Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, the vehicle signal system based on machine vision of the present invention is an additional set of car signal lamp system loaded on the existing driving system, and can be manually controlled to realize loading and unloading (i.e. adding a switch on the power supply of the system, and not realizing loading when the power supply is turned off).
After the car signal lamp system of the present invention is loaded, the camera takes the car picture of the intersection and inputs the picture into the traffic signal lamp control chip (this embodiment takes P89C51X2BA as an example), so as to locate the car at the intersection through the P89C51X2BA chip, and at the same time, the P89C51X2BA controls the traffic signal lamp to be normally turned on and off, which is different from the existing traffic signal lamp system in that the P89C51X2BA chip sends the position information and the turn-on information of the car to the first HW3000 chip through the second HW3000 chip, the first 3000 HW chip receives the signal transmitted from the P89C51X2BA chip, displays the current traffic signal lamp information through the lcd, and displays the position information of the current car (which is determined by the P89C51X2BA and the automatic running condition of the car (obtained from the car driving system) to be the direction of the car, so as to determine the traffic rule according to which the car should run, the MSM8974AC compares the current traffic regulation information with the driver's driving information to determine whether the vehicle can be driven and should be driven in that direction, if the information is uniform, the vehicle is driven according to the driver's driving, if not, the MSM8974AC prohibits the vehicle from driving through the vehicle engine control chip (such as PCF 7936). In case of emergency, the system can be turned off, and the vehicle can run without following the information of the signal lamp.
PCF7936 is a chip developed and produced by NXP corporation, the working frequency is 100KHz-150KHz, and there are many models of vehicles using 46 chips in the market, from low-end vehicles to high-end vehicles. Besides PCF7936, NXP company has developed PCF7941, PCF7952, etc. electronic 46 chips of PCF79XX series based on PCF7936 chip, PCF79XX series electronic 46 chips are external antennas and integrated with remote control function or smart card function, etc., and PCF7936 encapsulates the antenna and chip into a functional particle.
The memory organization of the PCF7936 chip is divided into 8 pages (namely P0-P7), each Page32 bits, and 256 bits in total, and the whole memory can be roughly divided into two parts: TCFG (transmitter Configuration/association) located at Page0 through Page3 for personal setting and chip Configuration, UESR located at Page4 through Page7, not specifically defined, applied to USER data storage, and USER.
The HW3000 wireless transceiver module adopts a Hello HW3000 series RF device, which is an industrial high-cost-performance high-integration wireless transceiver chip. The module is an industrial-grade low-power-consumption sub-1G radio frequency transceiver module, and can fully ensure the link performance of user communication and the low-power consumption requirement of products by the aid of extremely low receiving current (8mA, low-power-consumption receiving mode) and leading 20dBm output power in the industry. Meanwhile, the module can support the hardware frequency hopping receiving function, and the interference of environment radio to the communication signal of the module can be effectively reduced.
