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 high-voltage 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.
