Title   Wireless data reading and transmission system based on infrared technology                                                  

Abstract

With the development of infrared technology, infrared technology are used in more and more areas. In this paper, a wireless data transmission system based on infrared technology is designed,mainly used in rapid residential energy meters reading problems ,can also be applied to other occasions where need the non-contact, real-time data transmission .

This paper mainly includes three aspects, first, according to the characteristics of the application of energy meters and requirements of non-contact infrared meter reading, infrared data transmission circuits of energy meters and reading meter were designed ; second, the meter reading instrument host circuit that makes MSP430 as control chip was designed; third, in order to ensure accuracy and reliability of data transmission, and because of limited energy, infrared transmission signal is weak, I study and design decimal communication protocol . 

The article designs wireless data transmission and reading system that is based on infrared technology ,and the system can achieve bidirectional signals between energy meters and meter reading instrument, data transmission, simplicity of operator , reliable work, low-power, store 10,000 sets of meter data (including the table number and measured data of energy meters), the system can also upload meter data with the host compute via the USB interface, can better meet the needs of the fast reading of energy meters .
