资料介绍

针对防盗报警,提出了基于单片机的门磁报警电路系统,系统简单易集成,可以用于集成电路的开发。此电路系统主要是由门磁和报警电路两部分组成,其中也涉及到单片机程序的控制。报警基本要求是电路系统反应灵敏,本论文首先利用了Multisim进行电路搭建与仿真,探讨分析了两种报警电路的设计即基于继电器的报警电路和基于与非门的报警电路在模拟单片机触发脉冲情况下的反应能力,几乎都能保持在ms级,从理论上表明了其电路系统的基本框架的正确性。同时,通过基于继电器的报警电路的实物应用测试表明此门磁报警电路系统可靠灵敏。

Aimed at anti-theft alarm,the magnetic door alarm circuit system based on MCU is proposed.The system is easy to integrate,which can be used in the development of integrated circuit.The circuit system almost consist of magnetic door and alarm circuit,it also contains the program of MCU software.The basic requirement of alarming is related with sensitive reaction of circuit system.The paper firstly use Multisim to set up and simulate circuit to discuss and analyze alarm circuit based on relay and alarm circuit based on nand gate.The research proves that the ability of two circuits' response is limited to millisecond level with the simulation of trigger pulse of MCU.It theoretically shows the ...
