Traffic signal control box production
Traffic signal control box production application and production
Traffic signal control machines generally refer to all electronic machinery, including cabinets, installed in the cabinet for controlling the operation of traffic lights. The signal control unit is the core part of the traffic signal control machine, which is used to select the display order of the signal lights and adjust the timing, and simultaneously control the operation of the road traffic lights. At present, with the development of traffic management integrated applications, a more integrated type of traffic signal control machine has emerged, which includes lane control units and other applications (such as variable information board control) in addition to the traditional signal control functions.
The main structure
Most modern traffic signal control machines are mainly composed of the following components: control unit, lamp phase output unit, flashing unit, output/input interface, power supply configuration and cabinet.
1, the control unit
The control unit is the core part of the signal control machine, mainly consisting of a central processing module (microprocessor, memory card, etc.), a display control panel module (keyboard and display), a monitoring module (a fault management module, or a conflict monitor), The power module is composed of four parts.
The main functions of the control unit include: selecting the timing scheme according to different traffic demand periods; receiving pedestrian and vehicle priority control signals; optimizing the timing scheme transmitted by the receiving center computer; performing lamp color conversion and monitoring the color conflict, monitoring the power supply voltage , monitor the bulb and the lamp phase output module.
2, the lamp phase output unit
The lamp phase output unit can control the light bulb to be turned off, including several sets of red, yellow and green controllable components. Each lamp phase output unit can provide red, yellow, green and pedestrian and non-motor vehicle red and green controllable components to control the light bulb to light off.
3, flashing unit
The flashing unit can provide a warning (including microprocessor module failure or green-green collision failure) warning, and the signal light flashes when the fault occurs. The flashing unit is generally located on the left side of the lamp phase output module, and has two controllable components, namely a flashing light and a power indicator light. Not only software flicker control, but also hardware forced flicker when important faults occur.
4, output / input interface
The input/output interface of the signal control machine provides internal and external transmission of traffic signal control information and control power supply connection, including countdown timer and peripheral device interface, vehicle detector interface, and various imported power output connector interfaces (output circuit drive, ie voltage Switching drive signal display), external communication connector (serial port, FSK modem, USB interface, optical transceiver, wireless transceiver, Ethernet switch, etc., one signal controller does not necessarily include all communication types).
5, power configuration
The power supply is configured to provide power to the signal controller, converting the external input 220V to the internally used DC 24V, 12V, 5V. The main power supply rated voltage of the signal machine specified by China's national standard "Road Traffic Signal Control Machine" is: 220V ± 44V, 50Hz ± 2Hz.
6, Traffic signal control cabinet
The signal control cabinet can protect the internal structure of the signal. The inner and outer surfaces of the signal cabinet and the control panel shall be smooth and flat, and shall be free from defects such as dents, scratches, cracks and deformation. The surface of the cabinet should have a firm anti-rust, anti-corrosion coating or lacquer layer. The metal parts should not be corroded or other mechanical damage. The sliding or rotating parts should be flexible, the fastening parts should not be loose, and the outer surface of the cabinet should not be possible. Sharp protrusions or corners that cause damage.
