摘　　要：近几年,工业计算机的安全应用日渐得到人们的重视,越来越多客户有增加机箱开盖即报警的需求。为保证其计算机的安全应用,将运用搭建纯硬件电路的方式,解决针对开机过程中或者软件初始化过程中无法及时对机器开盖入侵做出响应的问题,实现计算机开盖立即报警、消音和报警方式切换的功能。该方案可快速嵌入到工业控制的多种场合,实现工业智能控制技术。In recent years,the security application of industrial computer has been paid more and more attention,and more and more customers have increased the need to open the lid of the case to alarm.In order to ensure the security of the computer application,this paper uses the way of building a pure hardware circuit to solve the problem that the machine can not respond to the intrusion of the open cover in time during the boot process or the software initialization process,and realizes the function of the computer to open the cover immediately alarm,silence and alarm mode switch.The scheme can be quickly embedded in many occasions of industrial control to realize industrial intelligent control technology.
