The invention discloses a rear-end-collision-prevention early-warning device and method based on a microprocessor, and belongs to the crossing field of embedded technology and vehicle network technology. The rear-end-collision-prevention early-warning device comprises a power supply module and the microprocessor, wherein the microprocessor is respectively connected with a JTAG interface, a communication module, an alarm module and a radio frequency module, and the power supply module is respectively connected with the communication module, the radio frequency module and the alarm module connection. The rear-end-collision-prevention early-warning device uses a posture module to detect vehicle accident state and determine accident results all the time, and the radio frequency module broadcasts the accident vehicle state information. A communication network forms between rear-end-collision-prevention early-warning devices. When any device broadcasts a piece of accident information, other devices receive the accident information and forward the accident information once, and the alarm module reminds accidents ahead. The existing telecommunication base station is not used for broadcasting information, thereby reducing complexity and communication time-delay. No microwave radar and supersonic wave range finding apparatuses are installed, thereby lowering cost. Good non-light of sight early-warning function is provided.
Description
technical field [0001] The invention relates to a microprocessor-based anti-rear-collision early warning device and a method thereof, in particular to the intersecting field of embedded technology and Internet of Vehicles technology. Background technique [0002] Since the 1960s, foreign countries have begun to study the anti-collision warning system of automobiles. Among them, Germany and Japan have the most advanced research levels, but due to the microwave theory and cost reasons at that time, there has been no breakthrough. Mitheus” plan to re-drive the research on radar systems. The basic principle of the current radar anti-collision warning system is: use 76-77GHZ microwaves to detect objects within 150m, and trigger an alarm mechanism when the safe distance exceeds the limit. By the 1990s, the ASV program jointly participated by Japanese automobile manufacturers made the anti-collision warning system more intelligent and complex. Subsequently, Toyota Corporation of J...
