The Application of Infrared Remote Control Technology in the Parameter Management……

A parameter code lock system for Intelligent Instrument based on infrared remote control technology is designed to solve the problem that the system parameters of Intelligent Instrument can be easily changed while being used. With the combined usage of special coding chips and software decoding technique, this system has a simple circuit, high reliability and low cost. This article presents hardware circuit principle and software decoding thought. The practice proves that the code lock system is of reasonable hardware circuit,correct decoding of software and convenient operation. Thus, it has been widely spread and applied. http://www.sj-ce.org/paperInfo.aspx?ID=189
