Road obstacle detection prompt alarm system and alarm method thereof

Abstract

The invention discloses a road obstacle detection prompt alarm system and an alarm method thereof. The system comprises a 220V single-phase alternating current power supply, radars, an AC / DC converter, relays, a main control unit, a power meter and a lamp brightness adjusting device. The radars are installed on street lamps of a road. Each street lamp is provided with one radar; and the radars areused for detecting obstacles on the road. The 220V single-phase alternating current power supply comprises two paths, wherein one path passes through the AC / DC converter to be direct current, and theother path passes through the relay and the power meter to provide a 220V power supply for the street lamps; the main control unit controls on and off of the street lamps through the relays; the maincontrol unit adjusts the brightness of the street lamps through the lamp brightness adjusting device; and the main control unit receives detection results returned by the radars in real time. Suddenfaults of the road can be compared and detected; when obstacles are detected, the front and rear adjacent street lamps are linked in time to enhance the brightness of the street lamps; and meanwhile,the system reports dangerous situations to a system background to prompt road maintenance personnel to clear the faults in time.

Description

technical field [0001] The invention belongs to the technical field of obstacle detection, and in particular relates to a road obstacle detection prompt alarm system and an alarm method thereof. Background technique [0002] The relatively remote roads in cities often do not turn on street lights or the street lights are relatively dark in order to save electricity. If obstacles suddenly appear on the road and are not cleaned up in time, accidents may occur, resulting in casualties and property losses. Contents of the invention [0003] The object of the present invention is to provide a road obstacle detection prompt warning system and a warning method thereof to solve the above problems. [0004] The technical solution that realizes the object of the present invention is: [0005] A road obstacle detection prompt warning system, including 220V single-phase AC power supply, radar, AC / DC converter, relay, main control unit, power meter, lamp brightness adjustment device,...
