| City Lighting and lighting engineering has important significance for municipalconstruction. City street lamps and landscape lighting is the most basic public facilities,which is related to the road traffic safety and the people living facilities. Now the societyhas already entered the high-tech, modern atmosphere rich era, people’s daily life has beento achieve automation.GPRS technology is a kind of high speed transmission, always online, according tothe actual consumption flow charging of a high speed data processing technology, access toa wide range, high-speed data transmission, fast connection, can keep forever online,according to the calculation cost flow, applied to various communication protocols support,realize the point to point communication. Compared with the existing wirelesscommunication technology, decided to realize remote communication, using GPRStechnology to realize data transmission, detection and control of street lamp lighting.This paper is the research and development of intelligent lighting GPRS three remotemeasurement and control device based on hardware design and software design, finallyachieve the functional requirements. Equipment can do telemetry, remote communicationand remote control of three remote, single node detection, control group control nodedetection and loop detection. Intelligent lighting GPRS three remote control device usingGPRS module and the Internet connection based on the measuring plate measuring device,electric control box three-phase power supply voltage phase voltage value, current value12. Voltage and current detection plate on the detected values by IC treatment to obtain theeffective value of voltage, current, power and power factor, and through the LCD display.Based on the power supply board of intelligent lighting GPRS three remote control devicecan choose any one phase of power supply line and the zero line.Intelligent lighting three remote control device of the design of the software adopts"three layer structure of high-level components layer underlying component layer andhardware component layer". ZigBee technology is also used to realize the transmission ofdata relay between point and point lights, the realization of ad hoc network street between.The PC software is used as an auxiliary function, can realize the street lamp working parameters in the monitoring center detection to three remote control device to detect andsend control command, can also be time control command to the three remote controldevice.This project is a wireless lighting control technology application, the purpose ofdesign to the street lamp lighting control. Three remote measurement and control devicethrough the long-term test, stable operation. Device is mainly based on the existingwireless technologies, a lot of lighting control system, has the very good application value. |
