压力传感器延时报警系统的研究

Research on Delay Alarm System of Pressure Sensor

基于压力传感器工作原理制作的报警装置具有低成本、不易破解的特点,报警装置由压力传感器模块、电源模块、计时模块、报警模块等构成。压力传感器可放置在盗贼易入侵且比较隐蔽的位置,如地板、墙面等,当盗贼触碰压力信号后,延时报警装置开始计时,计时功能完成后触发报警;如果是误碰压力信号,可在任意时刻解除报警。

The alarm device based on the working principle of pressure sensor has the characteristics of low cost and difficult to crack.It is composed of pressure sensor module,power supply module,timing module,alarm module and so on.The pressure sensors can be placed in more hidden positions where thieves invade,such as floors,walls,etc.When the thief touches the pressure signal,the delay alarm device begins to time,and the timing function triggers the alarm after the timing function is completed.If the pressure signal is touched by mistake,the alarm can be lifted at any time.
