设计并实现了一款可用作无线传感网络节点的新型智能气体压力仪表,它具备对被检测信号进行检测变送、数字显示、无线发送、过限报警等基本功能的同时,还允许用户自由选择过程数据或开关点。基于独特的电路设计,它具备同步输出数字开关量和模拟信号量的能力。另外,它的开关点精度和开关频率都较高,特别耐用。软件开发环境为MPLAB IDE v8.86,调试器选用MPLAB ICD 3。
A new type of intelligent gas pressure gauge which can be used as a wireless sensor network node is designed and implemented. It has the basic functions of detecting and transmitting the detected signals, displaying digital signals, sending wirelessly and over-alarming, and also allows users Free choice of process data or switching points. Based on a unique circuit design, it has the ability to synchronously output digital switches and analog signals. In addition, its switching point accuracy and switching frequency are high, especially durable. The software development environment is MPLAB IDE v8.86 and the debugger is MPLAB ICD 3.
