摘要

本文主要阐述了远程多路遥控起爆系统的设计与实现，给出了系统设计方案和电路设计。在系统方案设计中，从可靠性、实用性和经济性出发，采用了数字通信技术来实现遥控功能;并应用单片机作为主控CPU实现对系统的控制，有效地减少了系统的体积和功耗，保证了系统满足设计指标要求。

通过控制面板由用户输入指令,在单片机中完成对指令的编码后送到无线发射模块将指令发送出去。接收模块将接受到的信号进行混频、解调处理后送到单片机,由单片机完成指令的译码,将译码后的指令输出给执行机构,控制雷管的状态和动作。该方案具有输出控制灵活、可靠性高的特点。

为适应军事技术向信息化、智能化方向发展的趋势，还研究设计了一种多路遥控起爆器。该系统主要由发射机单元、接收机单元和雷管组成。本文论述了系统设计的总体方案，发射端、接收端和单路起爆电路的设计，以及系统实现的方法和原理。该多路遥控起爆系统实验结果表明，遥控距离最远达5000m，发射控制成功率98%,，，具有较强的抗振动、抗冲击、抗电磁干扰、抗雷击能力，并具有良好的密封防潮性能。该系统还可作为矿山和工程爆破的一种爆破器材。

ABSTRACT

The thesis primarily sets forth the design and realization of the multi-route remote control blasting system, gives the design scheme of the system and circuit devisal. During devising the system scheme, digital information technology is used to realize the remote control function;the single chip microcomputer is used to act as CPU to control the entiresystem to lessen the power expense and the size of the system effectivelyand to insure the system satisfies the devising standard.

Users input instructions by control panel, then code the instruction in MCU and transmit the instruction by the transmit module. The receiver modules mix, demodulate and carry the instructions to MCU, then MCU decodes and carries the instruction to executive unit and controls the state and action of exploders .This scheme has feature of flexible output control and reliability.

For meeting the development of military technology into informization and intelligentization, a multi-way remote controlling igniter consisted of generating unit, receiver unit and detonator ,was developed. The present paper discussed the overall design scheme of this system,

including the designs of generating sector, receiver sector, single circuit initiating . Test results showed that the system could work in the maximum controlling distance could reach far to 5000m, with 98% of successful rate .Tests also gave evidence that the system was of good abilities in terms of its vibration-relive, impact-resistance, anti-electromagnetism, thunder-proof. Besides it had good sealing and wet-resistance. Therefore it can be applied in mining and other blasting engineering.

Keywords:Multi-remote Control; Bombing Trigger; MCU(single chip

microcomputer).
