Traffic signal control machine was achieved through control of traffic lights control road traffic control system. Usually driven by a power supply module, CPU control part, headlamp unit, a signal fault detection, a panel operation (some controller without control panel), and other components. General installation at intersections, must adapt to the various complex outdoor environment, such as high temperature and high wet, cold and hot air circulation, electromagnetic interference, surge impact, and so on bad weather conditions.

Traffic signal control machine according to the control pattern classification, can be divided into five types: (1) a single point of section of traffic signal timing type; (2) a single point of adaptive traffic signal; (3) a single point of networking debugging traffic signal; (4) centralized coordination of traffic signal; (5) pedestrian crossing trigger type traffic signal. According to the power supply mode to points can be divided into three types: (1) mains power supply (AC220V/AC110V) signal; (2) solar dc signal (wired/wireless transmission); (3) solar grid complementary signal.

At present, the signal control machine production enterprise level the good and bad are intermingled, have done very good high-end of the state-owned enterprises, there are also many mid-range of private enterprises. In domestic dozens of signal system production enterprises, able to stand out from the nature is with independent intellectual property rights of high-tech enterprises, most of them are in coastal cities.

Zibo peng hui electronic technology co., LTD. The main production traffic lights, traffic lights, traffic signal controller, solar traffic lights, and other products, and for the user need to design special production. Please click http://www.knur.com.cn for more information.
