    摘要: An in-vehicle life detection system and detection method thereof are provided. The system includes a control unit, an electromagnetic wave detection module, and a warning module. The method includes following steps: vehicle condition identifying step, life form detecting step, and warning step. Upon receiving an engine off signal and a driver absence signal, the control unit emits a detection activation signal, activating the electromagnetic wave detection module to emit an electromagnetic wave for detecting a life form. When the life form is detected, the warning module sends a warning signal, indicating that the life form is left in the vehicle when the vehicle is in the engine off status with the doors closed. Thus, the tragedy of a life form remaining inside the vehicle incapable of calling for help is avoided.

    摘要: A multi-frequency processing device of a tire pressure detector and processing method thereof are provided. The device includes an oscillator providing an oscillation signal as a basis frequency; a microcontroller storing a first and a second frequency information; a phase lock module receiving the oscillation signal and generating a first and a second target frequency according to the first frequency information and the second frequency information; and a transmission module receiving a data from the microcontroller in a first mode, and generating a signal frame formed of the first and second target frequency carrying the data, so as to transmit the signal frame. Therefore, the transmission frequency does not have to be set in advance, improving the convenience of usage.
