With the modernization of urban construction, the development of urban lighting facilities has developed rapidly. Road lighting street lights, decorative lanterns, music lighting fountains, lantern lawns, lantern clusters, building spotlights, building lighting contours and other unique lights constitute beautiful Night scene system of city lights. However, while beautifying urban life, the maintenance of lighting equipment, power consumption, and management and control of street lamp systems have also become new problems. Therefore, in modern city construction and planning, energy-saving and efficient intelligent street lamp monitoring system is indispensable.
There are two common types of intelligent street lamp monitoring system: GPRS wireless equipment + centralized monitoring system of intelligent node control equipment and network monitoring system of GPRS wireless equipment + Zigbee terminal control node. The system topology diagram is as follows:
