Abstract: A mobile reader for waking up a tire pressure detector by using 2.4G signal encoding includes a reader MCU electrically connected to a reader memory unit, a reader high-frequency transceiver module, a reader main controller, and a reader input/output module. The reader MCU does not include a reader low-frequency circuit or a reader low-frequency antenna. The low frequency being less than or equal to 150 KHz. A display unit is electrically connected to the reader input/output module. A keyboard is electrically connected to the reader input/output module. This invention eliminates the need for using both high-frequency antennas and low-frequency antennas simultaneously to eliminate the issue of the excessive variety of antennas used in conventional tire pressure detection systems.

Abstract: A 2.4G signal encoding wake-up operation tire pressure detector includes a first TPMS-MCU electrically connected to a first TPMS memory unit, a first TPMS communication interface, a first TPMS main controller, and a TPMS high-frequency transceiver module. The TPMS high-frequency transceiver module includes a TPMS-BLE radio frequency unit, a TPMS-OOK radio frequency unit, and a TPMS high-frequency antenna. The TPMS-BLE radio frequency unit, the TPMS-OOK radio frequency unit, and the TPMS high-frequency antenna use a shared circuit. A second TPMS-MCU is electrically connected to a second TPMS memory unit, a second TPMS communication interface, a second TPMS main controller and the first TPMS-MCU. The first TPMS-MCU and the second TPMS-MCU do not contain TPMS low-frequency circuits or TPMS low-frequency antennas, and the low frequency is less than or equal to 150 KHz. This invention eliminates the need for using both high-frequency antennas and low-frequency antennas simultaneously.
