摘　　要：为了解决单一参数评价机油性能的局限性,实现机油快速、方便、准确的综合在线检测,研制了便携式机动车机油性能检测仪。该检测仪以机油性能为研究对象,提出一种通过对机油黏度、介电常数以及温度的检测来实现机油性能评价的在线检测方法。RS-485通信模块将采集到的数据信息由变送器传送给PIC单片机进行处理,单片机通过接收按键信号将测量到的数据值显示在LCD液晶屏上。试验结果表明,该检测仪性能稳定、使用方便、误差小。To solve the limitation of evaluating the performance of engine oil by single parameter, and implement comprehensive online detecting the engine oil quickly, easily and accurately, the portable performance detector for engine oil of motor vehicle has been developed. With the performance of engine oil as the researching object, the online detection method of evaluating performance of engine oil is realized by detecting viscosity, dielectric constant of engine oil, and temperature, is proposed. The data information collected are sent to PIC single chip machine from transmitters via RS-485 communication module;through receiving push button signal, the measured data are displayed on LCD screen by single chip machine. The test results indicate that the detector operates stably, easy to use, and with small error.
