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.
