为了监测火力发电机组转子转速度、转加速度和零转速度，以８０ｃ１９８微处理器为核心，从测速齿盘或鉴相脉冲上取信号，由信号的周期计算出转速度、转加速度和零转速度。介绍了工业环境中长期连续可靠测量所需的周到而全面的考虑，着重介绍测量原理、传感器选择、信号调理、功能的转换、系统自检、报警设定及线路故障防范、标准输出等。几年来仪器现场运行结果表明，文中的观点是正确的，对其它参数监测也有借鉴作用。
In order to monitor the thermal power generator rotor speed, add speed and zero speed, with 80c198 microprocessor as the core, take a signal from the speed measuring gear or phase-detection pulse, calculated from the signal cycle speed, add speed and zero rotation speed. The thoughtful and comprehensive consideration of continuous and reliable long-term measurement in industrial environment is introduced. The measurement principle, sensor selection, signal conditioning, function conversion, system self-test, alarm setting, line failure prevention and standard output are introduced. Over the past few years the results of the operation of the instrument shows that the article’s point of view is correct, and other parameters for monitoring also have reference.
