基于芳纶被复线远距离排爆头盔语音通信系统设计及应用
Design and Application of an Ultra Distance Voice Wire Communication System Based on Aramid Linear Connection for Explosive Disposal Helmet

本文介绍了一种能够应用在爆轰环境中的远距离语音通信系统，系统采用有线通信的方式，主要由芳纶被复线、排爆头盔、前端语音控制盒和后端通话器等组件电路组成。本文着重论述了远距离排爆头盔语音通信系统的组成、系统组件设计原理、语音通信系统如何与排爆头盔的有效配合以及在排爆服产品当中的应用。整个系统采用两线制作为传送信道，采用全双工通讯方式，语音数据的发送和接收由两芯轻型芳纶被复线完成，线缆长度可达数公里。利用芳纶被复线重量轻、强度高、衰减小、柔软等优点，大大提高了信号传送效率和减轻排爆人员的负荷能力。在爆轰现场的环境中，基于芳纶被复线远距离排爆头盔语音通信系统的应用解决了排爆人员与现场指挥人员进行远距离实时语音清晰通话，为指挥人员及时了解现场情况起到极为重要的作用。
This paper introduces an ultra distance system device based on voice wire communication in the exploding fields, the system is made up of several modules, including aramid linear, explosive disposal helmet, forward controlling and amplying voice device and central communicating device, etc. This paper important introduces the component and the circuit design of system based on voice wire communication applying in explosive disposal helmet in the ultra-away distance、how to cooperate with helmet efficiently and mainly apply in the explosive disposal suit. It can be connected with two lines, several kilometers in length, using double transmitting way. It greatly improves data anti-jamming ability, and the transmitting efficiency and lightens the whole weight of load for the explosive disposal staff. For safety, the backward central commander must be placed far distance from the exploding fields. The application of an ultra distance system device based on voice wire communication and aramid linear in the explode fields, which it can settle out voice communication. Expediently, which it can be helpful to commander to know more information of the explosive scenery and play an important role in disposing explosive fields.
