Embodiment Construction

[0072] 1. Install a 2.4G free frequency band, anti-interference control module on the signal light poles in all directions at the intersection of traffic lights, such as the one produced by Chengdu Xigu Shuguang Digital Technology Co., Ltd., with an outdoor power of 3 milliwatts and 50 Milliwatt, WV2436C and WV2436B modules with switch control circuit, of which WV2436B is a central control module with long-distance communication capabilities, both modules are packaged in a metal waterproof box with a 4.5 cm long antenna, waterproof box It can be directly fixed near the signal lights on the light pole, and each signal light is connected to the corresponding signal light control interface of the control module, (if necessary, the pedestrian traffic signal light can also use a sub-control module separately), and then the driving power of the signal light and the control Connect to the power interface of the module. The signal lamps in each direction will work according to the pre...

Abstract

The invention relates to wireless control for traffic lights. The invention provides a wireless control system with the advantages of economy, flexibility, reliability and high efficiency through using the current latest micro-power wireless communication technology with high integration and reliability, in order to overcome the following shortcomings in the prior control system of traffic lights of large bulk, high cost, inconvenient assembly, maintenance and use. The invention uses a plurality of traffic light control modules with high integration directly connected with traffic lights and dispersedly mounted in different directions at the same intersection to replace a crossing machine performing concentrative control to the traffic lights of the whole intersection, and allows the dispersed control modules to organically connect together to realize working in harmony through the wireless way. The wireless control system not only significantly reduces construction cost and maintenance cost of the system, convenient to assemble and use, but also remarkably improves traffic management level of the whole city.

Description

technical field [0001] The invention relates to wireless communication technology and traffic signal lamp control management technology. Background technique [0002] At present, the control and management system of traffic lights at urban intersections in domestic cities generally uses the way of control and management of crossing machines (switch control cabinets), that is, a crossing machine is installed at each or several intersections to control the traffic lights of this one or several intersections. Centralized control. The switch of each signal light at the intersection of traffic lights is placed in the crossing machine cabinet. Ideally, these crossing machines will be connected together by optical fiber or other communication cables to the urban traffic control center. [0003] The existing control system has the following problems: [0004] 1. Since a crossing machine is used to centrally control all traffic lights at the entire traffic signal intersection, the ...
