What are the structural design requirements of traffic light?
The traffic light structural design requirements encompass several key components: the power supply unit, CPU unit, detector unit, signal control output unit, communication unit, and others. Manufacturers must construct both the interior and exterior of the traffic signal cabinet using anti-rust and anti-corrosion materials.
Physical structure performance requirements:
The traffic signal cabinet must feature a bright and smooth interior, surface, and control panel, devoid of dents, scratches, cracks, or deformation. Furthermore, a robust anti-rust, anti-corrosion coating or paint layer must adorn the surface. Metal parts should exhibit no rust or mechanical damage, with flexible sliding and secure fastening. External surfaces must lack any corners that could cause damage.
Cabinet structure:
The cabinet structure necessitates ample internal space to facilitate heat dissipation, equipment installation, operation, and maintenance. Designs should prioritize rain prevention and minimize dust and harmful substance intrusion. Measures should also be in place to prevent water ingress. With the traffic signal controller boasting sufficient mechanical strength to withstand normal transportation and handling operations.
Cabinet doors must open to an angle exceeding 120°. It equip with a sturdy common door lock and additional protective features to deter tampering and unauthorized access. Durable and elastic sealing gaskets must seal the joint between the door and cabinet without any gaps. Ensuring the door remains intact and functional. Additionally, door alarm equipment is mandatory.
The structural design requirements of traffic light is necessary. A storage box must be provided for housing user manuals, instructions, wiring diagrams, repair records, and other relevant materials. The capable of accommodating A4 layout materials with a minimum thickness of 20mm. Furthermore, a manual control switch box should be installed in the upper-middle section of the cabinet for convenient access.
