TIRE PRESSURE MONITORING SYSTEM AND ONBOARD TIRE PRESSURE DEVICE THEREOF

摘要

A tire pressure monitoring system and an onboard tire pressure device thereof are provided. Wherein, the onboard tire pressure device (2) integrates a central monitor (21) and a signal matching device (22) of the prior tire pressure monitoring system and can be connected with the electricity-acquisition interface (24) of a cigar lighter in physical structure. The onboard tire pressure device (2) is equipped with a battery (229) independently. The battery (229) can be charged via the electricity-acquisition interface (24) of the cigar lighter to achieve the further integration of basic electrics. The tire pressure monitoring system and the onboard tire pressure device of the invention is easy to use, especially convenient to mount and debug.
