基于状态转换的低功耗胎压监测模块设计

Design on Low Power Consumption TPMS Based on Status Conversion

对影响压力传感器胎压监测模块功耗的因素进行分析,并介绍低功耗胎压传感模块的工作状态及转换关系。基于传统的初始化、工作、停机状态转换流程提出一种增加避免长操作等待的待机模式的改进方案。经过实际测量与试验,胎压监测系统的工作功耗明显降低。

In this study, the factors affecting the power consumption of TPMS sensor were analyzed, and the working status and conversions related to power consumption were introduced. Based on conventional finite status with initializing, working and stopping, a standby mode to avoid long operation waiting was presented. Test results showed that, the power consumption of the new TPMS system was significantly reduced.
