Design And Application Of Intelligent Control Switch For Multi - Mode Communication

In recent years, wireless communication is the most widely-used and the fasted developed technology in the field of information communication. Because of its no need for wiring and high flexibility, making up for the shortcomings of cable network. Meanwhile, different works of life attach higher expectation to the safety, reliability, convenience and continuity of power supply. Therefore, the safety and reliability is guaranteed in many places by the remote control of the power. While the intelligent-controlled switch of multi-mode communication can solve all these problems and provide strong support for the safety and reliability of power supply. At present, the technology, which uses intelligent-controlled switch in monitoring and managing power, has been applied widely in many fields. Thus, it has broad market and great value.This thesis mainly explores how to monitor and control industrial power by various kinds of wireless communication modes, focusing on ZigBee, Bluetooth and WIFI. This thesis mainly talks about applying the chip S3C2440 as the main controller, and design the smallest system,and completion of each function module interface circuit design, and make the PCB, in addition, on the electric parameter acquisition module circuit design; The main communication mode of internal communication system is ZigBee wireless networking technology, and add the Bluetooth module and WIFI module then we could monitor it no matter how far; And set up the Linux embedded software platform, including the kernel transplantation, make the root file, write drivers, etc.and the electric parameter acquisition module and the coordinator software flow are introduced, finally to realize the combination of many kinds of communication mode, to achieve real-time monitoring of industrial power source. The paper also presents the tests and analysis of the relation between the transmission distances of electrical parameter acquisition system and the rate of packet loss, and test the accuracy of the data acquisition system. It also provides analysis and solutions for the interference in the process of communication, making this system more effective and more feasible.
