为有效地监测柴油机的工作状态,常需要寻找一种经济、可靠、易实现的方法以实时采集柴油机特定状态对象的数据信息。为此,运用AT89C55WD型单片机进行柴油机状态监测的数据采集系统应运而生。该系统可通过接入高精度传感器以传递压力、流量、温度等状态信号,然后经过放大滤波、模数转换(把模拟信号转换为数字信号),再经光电耦合电路送入单片
In order to effectively monitor the working status of a diesel engine, it is often necessary to find an economical, reliable and easy-to-implement method for real-time data collection of a specific state object of a diesel engine. To this end, the use of AT89C55WD-type single-chip diesel engine condition monitoring data acquisition system came into being. The system can access high-precision sensors to transmit pressure, flow, temperature and other state signals, and then amplified filter, analog to digital conversion (the analog signal into a digital signal), and then optocoupler circuit into the single
