汽车行驶工况记录仪,可用于汽车运输管理和为改进汽车结构设计及道路试验研究提供测试手段。本文介绍了 TP801单板机为主要结构形式并配有打印机及少量外围部件的实时式数字式记录仪的研制概况,并就该记录仪所具有的各项性能指标作了较详细的描述。尽管该记录仪离真正实用阶段还有一定的距离,但尝试还是有意义的。 Vehicle operating condition recorder, can be used for vehicle transport management and test methods to improve the design of automobile structures and road test. This paper introduces the development of real-time digital recorder with TP801 single-board computer as the main structure and with a printer and a few peripheral components, and describes in detail the various performance indexes of the recorder. Although the recorder is still some distance from the real practical stage, but the attempt is still meaningful.
