Micro-power wireless communication network technology based single-lamp lighting intelligent dimming system

Abstract

A micro-power wireless communication network technology based single-lamp lighting intelligent dimming system comprises a street lamp monitoring center, a single-lamp monitoring energy-saving module and a Zigbee wireless communication network system. The street lamp monitoring center is the whole area street lamp control management center and comprises monitoring center software and a wireless communication module. The single-lamp monitoring energy-saving module comprises a Zigbee wireless communication module and a single-chip microcomputer module for power acquisition and module remote signaling. The wireless sensor network system comprises a plurality of sensors which are distributed in certain geographic area. According to the system, the Zigbee wireless communication technology, the wireless sensor network technology, the digital frequency conversion control technology and the database management technology are integrated, and a high-pressure sodium lamp service life detection technology and a high-pressure sodium lamp digital frequency conversion dimming control technology are combined, accordingly, fine management of light control is achieved.

Description

technical field [0001] The invention belongs to the technical field of lighting intelligent control, and in particular relates to an intelligent dimming system for single lamp lighting based on micro-power wireless communication network technology. Background technique [0002] Road lighting is an important part of urban public facilities. At present, most of the road lighting systems in China do not adopt networked monitoring and management. They can only control lighting equipment with simple switch lights on a regional basis. Such control methods cannot be real-time. It is impossible to adjust the brightness of the street lamp according to the specific situation by obtaining the status of each street lamp, and it cannot effectively save electric energy. [0003] Single-lamp energy-saving monitoring system refers to the installation of intelligent controls such as energy-saving and monitoring on street lamp poles to switch lights on the pole, power output (energy-saving, v...

AI Technical Summary

Problems solved by technology

Using wireless communication, its transmission rate is high, the transmission distance is long, and the unit cost is relatively high; because the cable transmission is limited by the distance, the farthest reliable transmission distance of the power carrier communication method is within 200 meters, and the transmission signal will be damaged if it exceeds 200 meters. With the increase of the transmission distance, it gradually attenuates. If the transmission distance is to be increased, a communication repeater needs to be installed, and the relay method is used to transmit one by one. The disadvantage is that the transmission rate will gradually decrease.
