Stm32 based on a high-speed car accident alarm system

Based on a high-speed accident STM32 automatic alarm system, belonging to the field of electronic devices. Object of the present invention is able to supply only by the vehicle power supply automatically after the accident before the accident lane case, the casualties and property losses as possible to reduce the speed based STM32 accident alarm system. The present invention is a STM32 minimum system, JTAG debug circuit, GPS antenna and the data processing circuit, MPU6050 module hardware circuits, SIM900A chip main circuit, SIM cards slot circuit, SD card hardware circuitry, TFT LCD module hardware, OV2640 camera chip module main circuit, USB interface and a power supply circuit, USB serial chip PL2303 main circuit. The present invention is fully automatic operation, without any operation after the accident, the video capture device to connect the central processor to send the coordinates to a particular car APP through GPRS wireless network, making it more advantageous action can be taken of the wounded such as police, ambulance and so on.
