Over the past 10 years, Internet technology and microelectronics technology changes the rapid development of the entire world. An increasing number of personal digital equipment, such as computers, mobile phones, DVD players, PDA, scanner, etc., to enter the people's lives. Most of the equipment is connected through cable. And the large number of cables to people's lives a lot of inconvenience, so many alternative cable technology emerged. In this paper, a short distance wireless communication technologies on the basis of the study, Based on the realization of a wireless digital transmission and single-chip computer chip wireless digital temperature acquisition system, system includes temperature acquisition modules, wireless data transceiver module two parts. I first wireless digital signal to the principles and methodology of the study Then the existing digital communications chip making a comparison and analysis, to choose the market to meet the design requirements, and the outstanding cost performance data nRF2401 transceiver, and uses the 10 AD7416 digital temperature sensor for temperature measurement and control, would greatly simplify the design, System performance is also more stable, the paper also gave details of this digital sensor structure and use; finalizing the design of the hardware and all the interface between the chip circuit Automatic temperature monitoring and alarm functions.

先翻译了一部分，待续。With rapid national economic development and fast increase demands of electric power, new power transmission requirements are put forward,especially in the rapid develop large city and heavily populated areas in city. Transmission capacity of existing transmission line can't meet the increasing needs of power loss and the floor space are the limiting factor of the high-capacity transmission conducter is urgently needed to solve this problem.
