【摘要】 针对车辆传动装置狭小约束空间、较大振动冲击、较多油污以及严酷恶劣的试验环境特点,提出一种基于Zigbee通讯技术的车辆传动装置旋转件、往复件近距离无线扭矩测试系统;采用MAX1452信号处理器将标定参数写入MAX1452内部的EEPROM,实现高温自动补偿;采用Zigbee协议实现模块间的近程无线通讯;采用CAN总线实现模块间的有线传输;经测试证明,该系统误差≤2(,性能可靠,现已成功应用于车辆的扭矩测试中,为设计仿真及故障分析提供依据。更多还原

【Abstract】 Vehicle transmission equipment has narrowspace、great vibration andi mpulsion、smeary、bad experi ment environment char-acteristics,a close quarters wireless torque measurement systemis proposed based on Zigbee communication technology used with revolving parts and to-and-fro parts.It can realize hightemperature compensation used MAX1452 signal processor written calibration data to EEP-ROM.it can realize wire and wirless communication used Zigbee protocol and CANbus.Practice shows error of the systemisless than 1 %,performance is credible.It has been applied on vehicle torque measurement successfully,and has been provided gist for design、si mulation and malfunction.更多还原
