摘要： A tire pressure monitoring system includes a main unit carried in a motor vehicle having one or multiple vehicle tires, and a tire pressure sensor installed in each vehicle tire of the motor vehicle and electrically connected to the main unit through a wireless communication SoC (system-on-chip) therein in a wireless manner. The wireless communication SoC of each tire pressure sensor includes a first communication protocol and a second communication protocol the related data of the respective vehicle tire. Thus, the tire pressure monitoring system improves data signal transmission efficiency and achieves dual-mode transmission.

摘要： A data transmitting device capable of configuring different operating frequencies for use by a tire pressure monitoring detector includes: a standard oscillator; a phase locked loop including a phase frequency comparator, a filter, and a pressure-controlling oscillator; a microcontrol unit electrically connected to the standard oscillator and the phase frequency comparator and adapted to store a first ratio and a second ratio; and a signal output unit electrically connected to the output end of the pressure-controlling oscillator and the microcontrol unit. The microcontrol unit allows a user to select and send the first or second ratio to the phase frequency comparator. The phase locked loop generates a target frequency signal according to the first or second ratio selected by the user. The microcontrol unit sends a data to the signal output unit, and the signal output unit outputs the data according to the frequency of the target frequency signal.
