Description: 变压器防盗报警器源码、原理图和PCB(protel 2004).MCU是STC89C58RD+.变压器防盗报警装置是针对野外的基站低压变压器被盗现象严重而开发的一种智能防盗报警系统。该装置采用RS422/ RS485通信手段，传输稳定可靠，维护方便等特点。弥补了传统集群式系统功耗高，通信距离短，购买价格昂贵等缺点。该产品采用高集成度的单片机作为控制核心，具有功能强，体积小，运行可靠等特点。-Transformer burglar alarm.Sound code, schematic diagram and PCB.MCU:STC89C58RD+.The transformer burglar alarm is aims at the open country the base depot low pressure transformer to rob one kind of intelligence security alarm system which the phenomenon serious develops. This equipment uses RS422/stably the RS485 means of communication, the transmission reliable, maintains characteristics and so on convenience. Made up the traditional colony type system power loss to be high, the signal distance was short, purchase price expensive and so on shortcomings. This product uses the high integration rate the monolithic integrated circuit to take the control core, has function, the volume is small, movement reliable and so on characteristics. Platform: |
