US 9,308,783 B2 · Tire pressure monitoring device

Abstract

The tire pressure monitoring device has a storage module, a receiver module and a control module. The tire pressure monitoring device retrieves a protocol by external indication or internal discrimination. The external indication is that the control module retrieves a protocol from the storage module according to an external signal, and then the control module compares the retrieved protocol with a protocol of a tire pressure signal received by the receiver module. If a comparison of the protocols matches, the tire pressure monitoring device decodes the tire pressure signal. The internal discrimination is that the control module compares different protocols stored in the storage module with a protocol of the tire pressure signal. If a comparison of the protocols matches, the tire pressure monitoring device decodes the tire pressure signal.
