AI Technical Summary

Technical Problem

In existing sensing-type smart streetlights, the far-infrared proximity sensor has a limited sensing range, and cannot provide timely lighting when it senses a vehicle passing by. Furthermore, the installation cost and failure rate are relatively high.

Method used

The sealed water bladder structure consists of a rubber base and a rubber dome. When a vehicle runs over it, the water inside the rubber base and the rubber dome is forced out through the induction water supply pipe and the one-way drain valve. When the water flow switch detects the water flow output, the PLC controller drives the lighting mechanism to power on, ensuring the vehicle's lighting while driving. The water is also automatically replenished through the water storage tank, realizing mechanical vehicle sensing.

Benefits of technology

It solves the problem of limited sensing range of far-infrared proximity sensors, reduces the failure rate, saves energy and is environmentally friendly. It also has a weak sense of obstruction when low-speed vehicles pass by, and a significant effect on slowing down when high-speed vehicles pass by, thus improving the overall lighting efficiency and comfort.
