这个基于C51单片机的双路压力监测报警系统是做的程设计，已通过验收，没有bug，功能更完善，所附包含proteus仿真文件，源代码，使用说明，可以做一个不错的参考。
所完成功能为模拟电路输入测量两路压力值，量程范围0~100MPa,带有LED报警功能，可以自行设置上限，压力测量值分时显示。
使用说明：
1.开始仿真，压力上限初始值为99MPa;
2.点击按钮button（要使数码管全部清零），在键盘处输入上限值；
3.上限值修改成功，重新开始显示，显示第一路时左侧带有上限值标识，显示第二路时左侧没有标识；
4.当测量数值超过了所设定上限，二极管闪烁报警；
5.结束仿真。
This dual pressure monitoring and alarm system based on C51 single chip microcomputer is a process design, has passed the acceptance, no bugs, more perfect functions, including proteus simulation files, source code, instructions for use, you can do a good reference.
The function is analog circuit input to measure two pressure values, measuring range 0 ~ 100MPa, with LED alarm function, can set the upper limit, pressure measurement value time-sharing display.
Instructions:
1. start simulation, the initial pressure limit is 99MPa.
2. click the button button (to make the digital tube all cleared), enter the upper limit value at the keyboard.
3. The upper limit value was modified successfully, and the display was restarted. The upper limit value sign was on the left side of the first path, and no sign was on the left side of the second path.
4. when the measured value exceeds the set upper limit, the diode flashes alarm.
5. finish the simulation. (2018-10-24, C51, 35KB, 下载2次)
