A guardrail anti-collision device with overspeed warning and lighting

Abstract

The invention discloses a guardrail anti-collision device with overspeed warning and lighting, which includes: a host computer and several lower computers; the host computer includes: an upper-level microprocessor, and an upper-level lighting module respectively connected with the upper-level microprocessor, Upper-level power supply module, upper-level speed measurement module, upper-level communication module and upper-level optical sensor; the lower computer includes: a secondary microprocessor, and a secondary lighting module, a secondary power supply module, and a secondary A communication module and a secondary optical sensor; the upper communication module of the upper computer is wirelessly connected with the secondary communication module of the lower computer, and the secondary communication modules of the lower computer are connected wirelessly. The present invention can not only solve the lighting problem of the curve, but also solve the problem of light pollution on the road surface of the viaduct; the present invention has an overspeed warning function, prompting the driver to reduce the speed to pass safely; car accident.

Description

technical field [0001] The invention relates to the field of traffic devices, in particular to a guardrail anti-collision device with overspeed warning and lighting. Background technique [0002] Speeding has become the "No. 1 killer on the road". The accidents are mainly caused by vehicles speeding and not following a safe distance. In order to avoid these accidents, in addition to safety education and knowledge popularization, some auxiliary reminder devices are needed to reduce traffic accidents. [0003] In order to supervise speeding, ITS technology is applied to traffic management. High-definition video capture equipment is generally installed on urban roads and expressways. However, due to the cost and installation of high-definition video capture equipment, it is only installed at certain distances and key locations. This is easy to make some drivers have a fluke mentality, speeding all the way on the highway, and slowing down to pass at the speed measuring point, t...

Problems solved by technology

Due to the cost problem, the car collision avoidance warning system has not been popularized in many cars

[0005] In addition, in urban road lighting, the traditional solution is to use high-pole street lamps as lighting appliances. The biggest drawback of this solution is to bring light pollution to the surrounding residents at night, which seriously affects the normal rest of residents, especially some Viaduct bridges in large cities pass between residential buildings, causing even more serious light pollution

[0006] There are also overpasses in urban roads. In order to solve the lighting of the road surface, high-pole street lamps are inserted on the beautiful overpass surface, which seriously affects the appearance. Among them, the approach bridges of these overpasses are curved, and the line of sight is not good Well, but often at this bend, there is generally no installation of road lighting lamps, which is prone to traffic accidents
