本文提出了一种用于农田喷灌工程的无线电遥控系统。此系统中指令形成是采用指令编码和纠错编码一次编成的方法,在指令编码时人为地赋予一定的多余度,用来纠正传输中产生的错误,省去了一次专门的纠错编码,使设备大为简化,且可靠性高。本文的重点是研究这种编码方法及其差错率。
This paper presents a radio remote control system for farmland sprinkler irrigation. The formation of the instruction in this system is a method of coding and error correction coding by instruction at one time, giving a certain degree of redundancy artificially in the instruction coding, which is used to correct errors in transmission, eliminating a special error correction coding, Make the device much simplified and highly reliable. The focus of this paper is to study this coding method and its error rate.
