摘　　要：随着排放法规对现代柴油机尾气中颗粒物排放的限制越来越严格,用于实时测量废气中颗粒物含量的漏电流式颗粒物传感器应运而生.基于SAE J1939协议设计了颗粒物传感器的控制系统,并进行了实验验证.结果表明所设计的控制系统可以对颗粒传感器输出的微电流信号进行转换和放大,实现了模拟量向数字量的转换.另外,集成了CAN总线技术的颗粒物传感器能够智能地处理自身采集的数据,并控制其自身工作状态,实现了与发动机其他控制单元数据的共享.With the increasingly strict emission regulations,a Leakage Current Type of particulate matter sensor is used for real-time measurement of the particulate matter contents in diesel engine exhaust.Based on the protocols of SAE J1939,its control system of the sensor is designed. The experimental results show that the micro-current signal outputs from the sensor can be transformed and amplified by the designed system,achieving the analog to digital conversion. In addition,the sensor integrated with CAN bus communication is smart both to handling its own data collection and to controlling its own operating conditions,sharing data with other control units of the engine.
