Research On Power Switch Controlling Systems In Computer Lab

As one of the hot communication techniques, wireless remote control technology mainly transmits the instruction signals produced by the transmitter into the receiver through the radio waves, and after decoding these signals, the receiver can take control of the loading by the Driving Circuit. The wireless remote control technology is suitable for the situation of one single master machine controlling multiple slave machines, and owing to the advantages of simple structure, low cost, saving resources and easy to extend and maintain, etc., this technology can be widely used in the fields of low-speed controlling system, such as environment monitoring, smart home control and intelligent industry control, etc..Depending on the illustration of the design scheme for remote power control system based on MCU, this thesis firstly designs the channel code for the remote power control system which is suitable for MCU. Secondly, based on the basic theory of communication, this thesis chooses the transmission medium suitable for the remote wireless control and presents the method of analyzing the loss in transmission lines, which aims to providing conveniences for designing and researching digital wireless communication techniques, and which also takes the factors, such as engineering cost and construction difficulty into consideration. Finally, this thesis designs the typical electric circuit concerning about the remote power control system based on MCU.Apart from the above contents, this thesis also illustrates the following two disadvantages existing in the traditional controlling techniques: one is complicated establishment, high cost and maintaining difficulties and the other is inconvenience in intelligent management. In order to solve these limitations, this thesis put out the following scheme based on the embedded MCU control and the wireless communication technique, that is, depending on the usual uni-polar RZ code, the signals are modulated and demodulated, so the whole system will be improved in anti-jamming performance, reliability and feasibility, and what's more, depending on the advanced techniques of embedded MCU control and wireless communication, the product will be more intelligent.
