Abstract


Sensor networks are integration of sensor techniques, embedded computer technology,distributed information techniques and communication techniques. they can be used fortesting, collecting and processing information of monitored objects and transferring theprocessed information to users.This article made more overall comprehensive analysis to the electric power line carriersensor netwoks which is on the basic of the character of transmit data. The characteristic ofpower line channel which is used to confirm carrier center frequency is discussed from thetransmission lines, noise, and channel attenuation in this paper. According to above analysisdesign network structure based on power line carrier solving the problems of the applicationof the actual networks cover;By comparing the present main electric communication and theadvantages of the modulation method, FSK modulation of spread spectrum technology wayof communications is chosen. A software spread spectrum scheme is designed to low the biterror rate;With microprocessor as the control unit, the software and hardware of sensornetworks is designed on the basis of TCC081C and TCS081. In the test and application partof the whole system test results and power lines carrier module are given, and gives thesystem in school administration of energy conservation of the application of the system.
