水文缆道采样器无线遥控的实现

The Study on a Wireless Sampling Instrument Using Ropeway to Communicate the Underwater Message

为解决水文缆道系统水文采样自动化程度不高,采样时间长等问题,提出了使用单片机为核心,利用缆道来传递信息,采用数字脉冲调制编码的电流场通信技术.采用这种技术实现了水文缆道采样器与岸上控制装置之间的无线双向通信,解决了多仓采样器的无线控制问题,并可对采样仓的动作进行有效的监控.

With the aim at the disadvantage of low degree of automatic equipment and long periods in sediments sampiing, the principle of a new wireless method is introduced in the paper. It uses ropeway to communicate the underwater message. The current field communication technology is adopted. The digital pulse code modulation is used as the communication protocol to exchange information between the underwater instnnnents and the surfaces＇. The technology solved the problem of remote control of the multi-container. The communication theory is introduced clearly and a brief decoding program is given. Many merits such as stabilization and anti-jamming are also presented. Furthermore, the application field of the technology is looked forward in the end of the paper.
