Multi-link Structure Of City Lights Energy-saving Micro Ultimate Wireless Controller

The thesis firstly gives an analysis of the present actual state of energy in our country and indicates that the energy situation in our country is very pressing, and then emphasizes the importance and necessity of economy of energy to respond to the call to develop the economy of the society in our country. Through analyzing the lighting conditions of the street lamps both at home and abroad, the thesis emphasizes the importance of the economy about the energy of street lamps, and through studying the present major measures of the economy about the energy of street lamps, the thesis analyzes the advantages and disadvantages of using the economic lighting lonely and using the method of turning some lamps off in midnight by wires. As there are so many medium and small cities that have no ways to give a great improvement on the existing street lamps, a wireless controller is produced, which can adjust the lighting time of street lamps based on different time without laying new lighting cable on a large scale again. And this kind of lighting controller is produced with the low cost wireless communication chips and microprocessor chips. It can control the lightings on the squares, streets and even the whole city expediently and easily by the multiplexing-diffused communication mechanism made from the software of the communication controlling. The rebuilding of the lighting system needn't dig the channel of cable and lay the cable again but just fix a micro-controller on the lamppost.In this thesis, it is expounded on the theory of thiswireless controller, To research the means using the ways of loading the signal to efficiently avoid the exoteric separation, which can develop the security of the wireless communication;it is used the multiplexing to transmit and receive repeatedly to ensure the reliability of communication;it is used the diffused communication mechanism to reduce the power of wireless transmitting to reduce the cost of components, and then to reduce the pollution of the frequency resources.In this thesis, it is rigorously demonstrated the hardware option of the wireless controller and communication plan and a hardware circuit of the wireless controller is designed, which is used to transfer the data received by the receiving module to the single-chip microcomputer and then transmit the data by the emitting module after it is controlled by the single-chip microcomputer to perform the serial data communication by its serial I/O port. A flow chart of the communication program is designed which is used to communicate the micro-ending wireless controllers by each other;and a source program of controller is also designed with assembly language. QTH emulator debugs the controller, then the debugged program is written into single-chip microcomputer to adjust the micro-ending wireless controller and analyze its capability. In this thesis, there are some points that should be noted in studying the micro-ending wireless controller and some problems that needed to be solved. The designed circuit and control method in the article suits commonly other designs of microprocessor system. The hardware and software is practicable and current in other proj ects.
