Talking about the city lighting intelligent wireless controller technical description: solar street light-litersol

1) The wireless communication network adopts China Mobile or China Unicom GPRS. Adopt reliable and high-reliability communication protocol TCP/IP, with automatic detection of GPRS network quality and automatic connection immediately after disconnection. (2) The industrial-grade anti-interference ability design is not affected by the electric spark of the original power distribution system. Make the equipment work reliably in the harsh environment of urban lighting with high dust, and the waterproof level reaches IP32. (3) The lighting distribution box GPRS-DTU adopts high-reliable industrial-grade products, which can set parameters such as IP address and port number for GPRS, information, and serial ports, so as to realize the judgment and processing of the connection status of the communication network. The acquisition and control unit adopts industrial communication protocol, and the coupling between modules adopts RS485. (4) Collect the AC voltage, AC current, power, switch lights and other states of each circuit of the lighting distribution box, upload it to the central server through GPRS, and consider lightning protection and surge protection. (5) The bearing capacity of the control output relay node is 220V/16A (OMRON). (6) High measurement accuracy and wide range: the acquisition rate is 0.4 seconds/channel, and the inspection period (all channels are collected once) is about 3 seconds. The analog precision can reach 0.2%, and the upper limit of the time precision error of switching lights is 5S. (7) The urban intelligent lighting wireless controller can collect the operating parameters and working status of the monitored equipment in real time, collect fault alarm information, and collect the on-off information of the interface switch in real time (judging the auxiliary contacts of the AC contactor). (8) The urban intelligent lighting wireless controller can receive and execute monitoring and control commands from the control center in real time through the China Mobile GPRS network, accept the instructions of the control center to turn on and off the lights, and also has the function of turning on and off the lights independently. According to the local sunshine time, different or the same switching period of each channel can be set, which can realize the control of panoramic night lights, midnight lights and holiday lights. (9) The LCD screen of the urban intelligent lighting wireless controller stores and displays the running status of each equipment in real time, and can display and adjust the electrical parameters of the equipment status (voltage, current, switch status, manual and automatic working mode conversion) in real time, and the monitoring terminal can The operating parameters can be set by themselves on site. And completely replace the original time switch device. (10) The wireless controller of urban urban intelligent lighting has perfect self-protection functions such as overcurrent and overvoltage. (11) Urban intelligent lighting wireless controllers have been widely used in building lighting and street lighting. Yangzhou Global Solar Technology Development Co., Ltd. focuses on the production and research and development of solar road lighting, integrates the practice and application of current intelligent lighting systems, and truly is an enterprise worthy of the name of Internet + road lighting.
