Traffic signal control method and apparatus

Abstract

The invention provides a traffic signal control method and apparatus. The traffic signal control apparatus includes a master control module, a power supply module, a plurality of light phase output modules and a plurality of terminal signal lights, wherein the power supply module is connected with the master control module; the output terminal of the master control module is connected with the light phase output modules; the light phase output modules are connected with the terminal signal lights; the master control module is connected with one light phase output module through a first line; the first line is hitched to a second line; and the second line is in parallel connection with the plurality of light phase output modules. For the traffic signal control apparatus, the master controlmodule can control the light phase output modules in a unified manner; the light phase output modules can communicate with each other; and after the master control module fails, the light phase outputmodules take the responsibility to control, thus avoiding the situation that traffic congestion occurs because the traffic lights at a crossing are disordered after the master control module fails.

Description

technical field [0001] The invention belongs to the field of traffic signal control, in particular to a traffic signal control device and method. Background technique [0002] Now domestic and foreign signal controllers all have the main board set on the main control module to drive the light phase output board (phase board), and use the electronic components on the light phase output board to give 220V output. After that, the corresponding light phase output board cannot work normally, causing the traffic lights at the intersection to be confused, thus causing the traffic at the intersection to be chaotic. Contents of the invention [0003] In view of this, the present invention aims to provide a traffic signal control device and method to cope with the situation that the light phase output board cannot work normally once the main board of the main control module fails. [0004] In order to achieve the above object, the technical solution adopted by the device of the pre...
