Abstract

The invention relates to a long-distance radar collision detection device and a method. Friction, collision and major personal safety accidents and the like are frequently caused due to a sight dead zone of a driver in an operation process of a large engineering vehicle at a port, a wharf and the like. The invention provides a stable and reliable device and a method which have strong environmental suitability and can effectively improve controllability and safety of the driver during operation of the large engineering machinery vehicle and a special vehicle. A data fusion technology of microwave radar sensors and ultrasonic radar sensors can effectively detect targets with different features in a complex environment, the influence of false interference is eliminated at the same time, and the controllability and safety of the driver during the operation of the large engineering machinery vehicle and the special vehicle can be effectively improved.

Description

technical field [0001] The invention relates to a multi-function, no blind spot, long-distance radar anti-collision detection device and method in the operation and reversing process of special vehicles, engineering vehicles, and large-scale engineering machinery. Background technique [0002] During the operation of large engineering vehicles such as ports and wharves, friction, collision and major personal safety accidents are frequently caused by the driver's blind spot. Most existing devices use ultrasonic radar. Due to factors such as short detection distance and poor stability, it is impossible to provide effective anti-collision alarms for situations such as large operating radius and poor driver's vision. [0003] At present, the traditional reversing radar mainly uses ultrasonic sensors, which emit ultrasonic signals and generate echoes when encountering obstacles. After the sensor receives the echo signals, the controller receives and processes the data to calculat...
