Research and Design of Distributed Long Distance Lighting Equipment Monitor System

In many areas such as building, road traffic, underground parking lot, large-scale market, stadium, and entertainment places, and so on, we usually need many lighting equipment, but conventional switch control usually needs work staff artificial control by wire style. This kind of style has poor real time and safety, so, in order to realize distributed long distance lighting equipment state control by work staff effectively at central control room, we design a set of wireless long distance lighting equipment control system through analyzing SCM MSP430F149 low power character, based on SCM MSP430F149 and wireless transmission chip nRF401. System is composed of upper PC, main controller, and each terminal controller. Upper PC controls main controller MSP430F19, and transmits control instruction to field controller, MSP430F149 controls corresponding lighting lamp switch state by wireless transceiver module. Upper PC can effectively complete wireless long distance lighting equipment control in real time. System transmission distance can reach 1000m in theory, which not only reduces physical route connection between terminal equipments, but also simplifies construction difficulty and complexity. System has many advantages such as good expansibility, convenient maintenance, and low cost, etc.
