The invention relates to the field of automobile tire pressure monitoring, in particular to a novel wireless tire pressure monitoring system. The invention relates to a novel wireless tire pressure monitoring system comprising a vehicle-mounted power supply and an in-vehicle sensing terminal, and further comprising a power supply protection circuit which is used for protecting the safety of the vehicle-mounted power supply and is electrically connected with the vehicle-mounted power supply, a wireless power supply module arranged on the wheel and electrically connected with the power supply protection circuit, a sensor driving module electrically connected with the wireless power supply module, and a dynamic tire pressure sensor arranged in an inflating valve of the tire and electrically connected with the sensor driving module. The vehicle-mounted power supply is adopted to replace a conventional dry battery power supply, so that the dynamic tire pressure acquisition circuit can stably work for a long time; the dynamic tire pressure sensor is adopted to replace a conventional static tire pressure sensor, and the object of tire pressure monitoring is the tire pressure variation.

    本发明创造汽车轮胎气压监测领域,具体涉及了一种新型的无线胎压监测系统。一种新型的无线胎压监测系统,包括车载电源和车内感知终端,还包括:电源保护电路,用于保护车载电源的安全,与车载电源电连接;无线供电组块,安装在车轮上,与电源保护电路电连接;传感器驱动组块,与无线供电组块电连接;动态胎压传感器,安装在轮胎的气门嘴中,与传感器驱动组块电连接。本申请采用车载电源代替常规的干电池电源,提使得动态胎压采集电路可以长时间稳定的工作;本申请采用动态胎压传感器代替常规的静态胎压传感器,胎压监测的对象为胎压变化量。
