Beschreibung
Zusammenfassung:	The utility model discloses an automotive anti-collision alarm device based on controller area network (CAN) transmission. A hardware part comprises a power supply, a speed measurement sensor, a pavement condition sensor, a millimeter-wave radar, a signal processing circuit, a controller and a sound-light alarm module. The speed measurement sensor and an acceleration sensor are connected to the input end of the signal processing circuit, the output end of the signal processing circuit is connected with a communication port of the controller through a CAN bus, and the controller is further connected with the output end of the millimeter-wave radar and the input end of the sound-light alarm module. The automotive anti-collision alarm device based on the CAN transmission can improves data transmission rate, enhances alarm real-time performance, and reduces rear-end collision of automobiles on highways.
