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.

Abstract: A collision avoidance method for transmitting data from multiple wireless tire condition sensors on a vehicle is executed by each wireless tire condition sensor having a unique ID and multiple different wake-up times. After the sensor is operated to sense data, the method has steps of reading the ID and computing a determination value with the ID and a variable, selecting one of the wake-up times according to the determination result, and after the selected wake-up time expires, transmitting the sensed data. As the selected wake-up times of the sensors differ from one another, data collision at the receiving end arising from data transmission from the sensors can be avoided. Additionally, besides the wake-up time, a time gap between data transmitted twice consecutively from each sensor can be employed to achieve data collision avoidance.

Abstract: A wireless tire pressure sensing device, a method for setting a standard tire pressure thereof and a wireless tire pressure sensing activation device adjust the tire pressure of each tire in a vehicle to a standard tire pressure according to a requirement of the vehicle after the wireless tire pressure sensing device is mounted in each tire, maintain each tire at the standard tire pressure for a preset time period or employ the wireless tire pressure sensing activation device to transmit a setup instruction to the wireless tire pressure sensing device to set a current tire pressure as the standard tire pressure. The wireless tire pressure sensing device can be set up with the standard tire pressure and conveniently modified. As no threshold value of tire pressure needs to be pre-stored, wireless tire pressure sensing devices with different threshold values are not necessarily prepared beforehand, thereby effectively lowering the stocking pressure on inventory management.
