Automobile collision early warning radar information system

Abstract

The invention discloses an automobile collision warning radar information system, which comprises system sub-modules such as a microwave radar module, a signal processing module, a data operation control module, a gravity accelerometer module, a GPS positioning module, a camera module, a speaker, a storage module, and a communication module. The system continuously reads and records radar data such as relative speed and distance information obtained by analyzing target radar signals in all directions during driving, reads and records driving status data, and merges the collision risk simulation array generated by the operation with the system preset The collision risk feature database is mapped and compared to obtain the collision risk level, and the horn is activated to perform a corresponding level of sound alarm; when a high-level collision risk occurs, the system uploads data to the Internet background server, which is applied to service providers for timely rescue and quantitative assessment of specific vehicles and drivers. The driver's future driving collision risk probability.

Description

technical field [0001] The invention relates to the field of electronic information, in particular to an electronic information system installed in a car, including system sub-modules such as a microwave radar module, a signal processing module, a data operation control module, a gravity accelerometer, a GPS positioning module and a camera module. Background technique [0002] Microwave radar is mainly composed of core module components such as antenna, transmitter, receiver, and signal processor. [0003] The radar transmitter generates electromagnetic waves, which are transmitted to the antenna through the transceiver switch; the antenna radiates these electromagnetic waves into the atmosphere, concentrates them in a very narrow direction to form a beam, and propagates forward; Reflections are generated in all directions, and part of the electromagnetic waves is reflected back to the radar to be acquired by the antenna; it is sent to the receiver through the transceiver sw...
