Intelligent traffic signal control machine instruction manual

A system introduction:

    Traffic Control System ITS (Urban) is one of the important components of the modern urban intelligent transportation system (Intelligent, transport, system), which is mainly used for the control and management of urban road traffic signals. Intelligent traffic signal control system, the design basis is GA47-2002 the road traffic signal control machine "standard. In addition, but also with reference to the Japanese policing Office Beijing three latest A03 traffic signal control system, draw the scats, SCOOTS system of part of advantages. Now the function of MD-XB type intelligent traffic signal control machine, system composition, as well as the use of methods, as follows.

Two, performance and characteristics of the system:

1, function and characteristics:

    Signal machine is flexible and can be set up for a variety of ways, such as multi - time multi - program, manual control, step control, command center, real-time adaptive control, etc..

Single point control: the signal light from the intersection is controlled by the traffic signal machine.

    The flash control: when the signal light yellow light according to a certain frequency of flashing, warning or alert to the vehicles and pedestrians.

Traffic control: according to the traffic demand, the command center issued a command to simulate the traffic signal machine manual control mode, traffic guidance.

    Step control: there are special requirements for the intersection, the traffic is unusual, but through the signal machine step by step, so that the release time is more reasonable.

    EMC electromagnetic compatibility design technology is used, the system has the ability to resist the thunder surge, the anti - cycle drop, the anti - disturbance, the ability of anti - static interference. Good protection for LED traffic lights.

With multiple control modes:

    Multi period multi scheme [with 4 sets of time control scheme, 16 time slots. 16 timing plan. Including yellow flash and lights out mode]

600W (AC220V), and all of the photoelectric conversion isolation technology.

    The biggest 8 passers-by line two color lamp driver and detection, each road driving ability is greater than 600W (AC220V), and all the use of photoelectric conversion isolation technology.

2, electrical performance index:

    Power protection: the clock can be guaranteed for 180 days without loss of power. With time of the program, can guarantee that 10 years is not lost.

AC input: AC220 (+ 20%) 50 + 2HZ;

AC input power is less than 20W

3, structure:

    Signal control machine is the main equipment in the system system of signal control, it by the digital tube display, control panel, with optocoupler isolation lamp driver board, switching power supply, a button board and other functional module plug-in board, and distribution boards, wiring terminal.

4, setting and display:

    LED screen, located on the panel of the signal machine, the 7 section of the 6 digital tube. Show the current running phase and the phase of the remaining time in normal operation
