MST－S型摩托车道路试验仪设计与研制

介绍了自行设计研制的MST-S型摩托车道路试验仪，该仪器运用光电传感原理，以AT89S52中央处理器为内核，通过在试验道路上设置光电反光器，在线检测出摩托车穿过此段距离的时间，计算出摩托车行驶中的各种参数，并存储于非挥发性时间管理储存芯片DS1642。MST-S采用了车载式燃油流量计，可准确完成油耗试验。测量中引入查询与中断结合方式以截取不同时间间隔，采用抗干扰技术提高仪器可靠性和测量精度，减小了测量误差。

Design and Research on the Road Testing Apparatus for the MST-S Motorcycle

The road tester of the MST-S motorcycle is a special apparatus on t he road trial. With the application of photo electricity transmission sense prin ciple, the instrument, whose kernel is based on the AT89S52 CPU, can inspect th e run ning time on line within the distance through the photoelectricity viewfinder th at is installed on the experimental road. Then it calculates the multiparameter in the motorcycle driving and saves the data into the DS1642 chip, which could r e sist the volatility and administer the time. The experimentation has the ability to complete the testing items for oil consumption veraciously via the mounted f uel flowmeter. Connecting the keyboard query with the intermittence in the surve y, the meterage can intercept various intervals. At the same time, for adopting the anti-jamming, which increase the experimental reliability and survey precis ion respectively, it reduces the trial error.
