摘要
文章介绍了以AT89C52单片机为核心、以ADXL202为主要探测部件的汽车制动性能测试仪。该仪器与机动车辆没有机械和电气连接,通过加速度数据的采集、运算,实现了对制动距离和制动时间的计算。给出了系统电路和系统软件的设计方案。该系统具有使用方便、硬件体积小、成本低、智能化较高的特点。
The New-style monitor for vehicle braking system performance with AT89C52 single-chip computer as core control and accelerometer ADXL202 as main detector is introduced. This instrument has no mechanical and electrical connection with motor vehicles, using collection and operation of acceleration data to realize the computing of braking distance and braking time. Design scheme of circuit and software are provided. The system has many features including small volume of hardware, low cost, high intelligent and so on.
