Research And Design Of Wireless Automatic Routines Control System Based On Time Service From COMPASS

BeiDou（COMPASS）Navigation Satellite System is a satellite navigation andpositioning system, which developed independently by China，so we have its fullintellectual property．The satellite offers precision positioning and time service toMilitary and Civilian．Compare with GPS，which is the classic representative ofGlobal Positioning System company，BeiDou（COMPASS）Navigation SatelliteSystem is a service system for only one area because that it is still beingdeveloped．Besides of offering highly precision and reliable positioning service alldaytime，the most significant feature of BeiDou is two-way communications，whichis general used in national defense，communication，federal establish and more area．As the pace of modern life continues to increase，and the continuous expansionof business scale，the precision and synchronous of the clock are highly demandedin most area．At present most daily schedule systems are still controlled by MCUtimer，therefore it must appear the decrease of GPS clock precision，the increase ofcumulate errors and out of sync even at the same place．In this thesis，a method toget precise time information through BeiDou（COMPASS）Navigation SatelliteSystem is proposed．The MCU used the real time signal which has been receivedand processed to be its clock source，then sent the precise time information to eachsubsystem through Radio Frequency Identification．So the users can realize timesynchronization at any given place and control daily schedule．According to standard time，time synchronization technology，BeiDou systemGPS clock principle and wireless radio frequency transmission principle thatintroduced in this thesis，a feasible design scheme with automatic control system ofwireless is given based on Beidou navigation satellite GPS clock．The productdeveloped by daily schedule control system based on BeiDou system GPS clock canbe used in situations where need correctly timing and control such as airport，trainstation，school，and enterprises and institutions etc．...
