Signal detection and control equipment and traffic signal failure automatic inspection system

Abstract

The invention relates to signal detection and control equipment and a traffic signal failure automatic inspection system. The system comprises an upper computer and a plurality of signal detection and control equipment. The upper computer and the signal detection and control equipment are connected through a wireless communication network. The signal detection and control equipment comprise interface circuits, acquiring modules, signal conditioning modules, main controllers, wireless communicating modules and power management modules. The interface circuits are connected to traffic signal terminal equipment, the acquiring modules are connected to the interface circuits and are used for acquiring electrical parameters of the traffic signal terminal equipment, the signal conditioning modules are used for determining failures of the traffic signal terminal equipment by the fuzzy neural algorithm according to conditioned acquired signals, producing corresponding traffic signal failure alarming information when the failures of the traffic signal terminal equipment are determined, and transmitting to the upper computer through the wireless communicating modules. By the aid of the traffic signal failure automatic inspection system, intelligent remote management and maintenance of the traffic signal terminal equipment can be implemented.

Description

technical field [0001] The invention relates to the technical field of traffic management, in particular to a signal detection control device and a traffic signal failure automatic inspection system. Background technique [0002] With the continuous development of society, road construction is also constantly improving, and traffic problems, especially traffic congestion and traffic safety in big cities, have become increasingly prominent. [0003] Traffic lights are an important part of traffic signal command. Traffic lights are the basic language of road traffic. Existing traffic signal lights can be divided into various types, such as motor vehicle signal lights, non-motor vehicle signal lights, crosswalk signal lights, lane signal lights, direction indicator lights, flashing warning lights, and road and railway level crossing lights, etc. [0004] At present, traffic lights have been widely used in road intersections, bends, bridges and other dangerous sections with po...
