基于ARM的新型高压脉冲电子围栏系统的设计

设计了一种基于ARM控制的新型高压脉冲探测器系统，重点解决了传统高压脉冲电子围栏系统在电源电压变化时高压脉冲输出不稳定及系统误报警等缺陷。系统硬件由单片机LPC2131、逆变器、功率传输器、远程控制与联网通信及围栏短路、断路，系统故障检测报警等部件组成。系统软件由A/D转换、采样比较、数字反馈、远程控制通信、防拆报警、看门狗等模块组成。由于采用了独特的二次升压电路，PWM反馈控制，硬件复位电路和多种抗干扰措施，经系统样机测试表明在电源电压波动20%的情况下，系统输出脉冲幅度稳定。此外，样机各项指标已通过国家安全防范报警系统的认证。

Design of New High-Voltage Pulse Electronic Fence System Based on ARM

A high-voltage pulse detection system controlled by ARM based on MCU is proposed and implemented.This system overcomes some defects such as weak robustness and false alarms existing in the traditional highvoltage pulse fence system.The hardware components of this system consist of a MCU LPC2131,inverters,power transmission,remote control and networking communications,fences short circuit,system fault detection alarming etc.The software part of the system consists of A/D conversion,sampling comparison,digital feedback,remote control communications,tamper alarm,watchdog components.The system has been assembled into a whole product prototype and tested under the real-world environment.Because many advanced techniques are adopted in the system such as secondary boost circuit,PWM feedback control,hardware reset circuit and multiple anti-jam approaches,the results show that the output pulse amplitude keeps stable with the power supply voltage fluctuating around 20%.Furthermore,this product prototype is verified to meet the specification of the national security alarm systems.
