Abstract: Wireless Radio Frequency (RF) technology, which can take the place of cable, has been widely used in many current fields as one of information technologies with widest horizon of development. The problems caused by the environment restrictions and the unfavorable conditions for cable wiring have been solved because of the emergence of the wireless. Its three important characteristics and advantages are low costing, low power consumption and peer-to-peer communication. During the design procedure, the system is divided into three major modules according to the functional structure, namely central control module, wireless transceiver module and computer dealing software, The central control module uses Sygnal company's low power enhanced 51 MCU C8051F310 as CPU, mainly to complete the data acquisition and processing. The wireless transceiver module is made up of TI CC1101 wireless transceiver chip, which mainly realizes wireless data transmission and The computer dealing software real-timely displays and deals with the data through visual, friendly programming interface, based on C#.NET. Final achievement of the system design is two compact communication devices, one of them connects with PC through RS-232 interface, System is operated through the graphical user interface based on windows, which is very convenient to operate. Debugging result indicated that data acquisition, processing and transmission could be achieved in wireless or wired way under the control of PC and it visually displays the results to the user, satisfies request of the wireless power monitoring data communication system, reaches the technical index.
