Design and Application of a Remote Detonation Tube Initiation System

利用PIC单片机与高可靠性的扩频无线控制技术,设计出包括无线遥控器、电子起爆器及配套电容式击发针的遥控导爆管起爆系统。现场试验结果表明,击发能量稳定性高,无线遥控起爆距离大于400 m。遥控起爆系统的应用不仅解决了现有导爆管起爆方式中存在的击发起爆可靠性差和导爆管消耗量大等问题,还丰富与优化了导爆管起爆系统,极大地增强了现场操作的便捷性以及起爆的安全性和可靠性,达到了节能减排和降本增效的效果。

A remote detonation tube initiation system consisting of remote controller,electronic initiator and a new type of capacitive firing needle was designed using PIC microcontroller and high reliable spread spectrum wireless control technology.Test results show that the firing energy value has high stability,and the initiation distance of wireless remote control is greater than 400 meters.The system could not only solve the initiation mode problems in existing shock-conducting tubes such as poor initiating reliability and large consumption of shock-conducting tubes,but also enrich and optimize the shock-conducting tube initiation system,accordingly,contributing to the great enhancement of the convenience of site operation and blasting safety and reliability,and achieving the energy conservation,emissions reduction and cost decreasing and benefit increasing effect.
