Intelligent traffic signal

XHJ-CW-GA-UTC365（4ULCD）type

Traffic congestion, traffic accidents and many other problems caused by the expansion of urban scale and the increase of vehicles have attracted more and more attention from governments and the public, and have also brought new challenges to traffic control and management.Vigorously developing intelligent transportation systems, rail transit signals make full use of computer technology, network communication technology, image processing technology and other advanced technologies to make traffic management more real-time, accurate and efficient, which is an important way to solve urban traffic problems.As the underlying execution unit of traffic signal control, the intelligent traffic signal control machine's intelligence and reliability directly affect the overall function of the traffic signal control system.In order to meet the actual needs of the development of intelligent transportation systems and combined with my country's actual traffic conditions, an intelligent signal that meets actual needs has been developed.This intelligent signal is based on a comprehensive treatment of the various advantages of various domestic and international signal models. It abandons the traditional complex structure and uses one control unit to complete the entire traffic control task, achieving a highly integrated and practical Reliable, easy-to-maintain intelligent management fully embodies the people-oriented management concept.The traffic signal can realize bus priority control and special guard tasks, which is consistent with the current bus priority policy proposed by the country.

The intelligent signal machine uses a high-performance processor, and the traffic signal control machine adopts a modular structure design, including the main control module, input module, output module, power module, temperature control module and GPS module. These modules are all highly integrated into one unit. Within, each module adopts high-speed, strong anti-interference synchronous serial communication method.Each module uses an independent European standard board, making the expansion and maintenance of the traffic signal more convenient.

The intelligent traffic signal also has a bus priority (BRT) function. The traffic signal performs multiple solutions according to the signal priority request, which can enable social vehicles to pass traffic light intersections smoothly without causing congestion while ensuring bus priority. situation.Among the rapid bus signal priority control systems implemented in more than a dozen cities across the country, our company's signal priority control system is very successful. The parameters of bus priority can be modified at will. Compared with the fixed signal priority of other units, our company's signal priority control system is very successful. The signal machine is better.Zaozhuang City, Shandong Province is a prefecture-level city north of the Yangtze River that has installed bus priority (BRT). This signal priority system uses our company's traffic signal control machine. The successful operation of this system has been welcomed by the citizens, and experts have given it high praise. Many units in the industry came to the site to visit and study.The main advantages of the signal are briefly introduced as follows:

Highly integrated main control unit, detection unit, and signal output unit are all integrated into one unit, and each unit implements a modular structure. 

● Desktop functions. All functions are clearly visible on the panel. Functions can be operated with one button. The structure is simple and clear. 

● Practical and reliable. Use as few components and boards as possible to achieve the same function, reducing the failure rate

 ● Easy maintenance. Each functional module is independent, and the physical shape of each board slot allows non-technical people to perform maintenance

 ● WYSIWYG color 7.5-inch LCD menu The simulated instructions on the central panel are set to correspond to the actual conditions of the intersection, making it easy to learn and use.

● BRT function The BRT function in the industry, with successful cases 

● Complete service, four maintenance tours per year, free provision of some spare parts, early pre-sales training and after-sales technical guidance, full training 

● Simple operation, adjustment of various functions and commonly used functions You can operate it without reading complicated instructions.

● The wiring is simple and divided according to the southeast and northwest areas, which is in line with on-site construction habits.

● Protection against leakage, lightning protection, output short circuit protection, and large current impact protection.
