摘　　要：利用Proteus设计了一种数字气压报警系统。通过MPX4115气压传感器获得与大气压相对应的模拟电压值,经过V/F转换器将模拟电信号转换为数字脉冲信号输入到单片机,单片机接收脉冲信号,经计算处理得出实际的气压值,最后通过数码管显示电路显示出来,并在Proteus上成功完成了仿真调试。结果表明本系统具有携带方便,操作简单,精确度高,适合远距离传送,并可根据具体情况设置警戒值进行智能监测报警,可实现不同环境下的分布-集中监控的特点。The barometer alarm system is designed using Proteus. The MPX4115 pressure sensor is adopted to get the analog voltage value corresponding to the atmospheric pressure, and the V/F converter to transform analog signals into a digital pulse input to the SCM. The SCM receives the pulse signal, calculates the actual pressure value, and finally the value displays with the LED display circuit. The simulation debugging of the digital barometer alarm system is successfully completed through the Proteus. The results show that this system has many features, such as simple operation, high accuracy, suitable for long-distance transmission, setting the warning value according to the specific circumstances to realize intelligent monitoring and alarming and realizing the distribution-focus monitoring under different circumstances.
