Introduction of wireless controller technology for urban smart lighting

1. The smart lighting wireless communication network uses China Mobile or China Unicom GPRS. The high-reliability communication protocol TCP/IP is selected, and it can actively detect the quality of the GPRS network and connect immediately when the connection is dropped.

　　2. Industrial-grade anti-interference ability planning, which is not affected by the electric spark of the original power distribution system. Make the equipment work reliably in the harsh environment of high dust in urban lighting, and the waterproof grade can reach IP32.

　　3. Smart lighting distribution box GPRS-DTU selects high-reliability industrial-grade products to meet the requirements of GPRS, information, and serial ports. All parameters such as IP address and port number can be set to complete the judgment and processing of the communication network connection status. The acquisition and control unit selects industrial communication protocol, and the coupling between modules selects RS485.

　　4. Collect the communication voltage, communication current, power, switch lights and other conditions of each circuit of the lighting distribution box, and upload it to the central server via GPRS. Lightning protection and surge protection should be considered.
