Tire pressure monitoring system wake-up device

A tire pressure monitoring system wake-up device comprising:

• an antenna unit (101), a main control board unit (102), a power supply unit (103), a radio frequency switch unit (104), and a database unit (105), the wake-up device (10) wirelessly or wiredly electrically connected to multiple tire pressure sensors (100) and mutually transmits signals, the antenna unit (101), the main control board unit (102), the power supply unit (103), the radio frequency switch unit (104), and the database unit (105) being interconnected, the power supply unit (103) supplying power to the main control board unit (102) and the antenna unit (101) for operation, the radio frequency switch unit (104) connected to the antenna unit (101) and including a receiving module (20) and a transmitting module (30), the receiving module (20) receiving signals transmitted by the antenna unit (101) and processing the signals, the transmitting module (30) sending the signals to the database unit (105) for comparison;
• the main control board unit (102) controlling the power supply unit (103) to supply and shutdown the power, controlling the radio frequency switch unit (104) to be turned on and turned off, and managing the database unit (105) to operate comparison operations, and
• when the antenna unit (101) receives a signal, the antenna unit (101) transmits the signal to the receiving module (20) of the radio frequency switch unit (104) within the wake-up device (10), after the receiving module (20) receives and processes the signal, the signals is indirectly sent to the database unit (105) for comparison via the transmitting module (30), when the signal sent by the transmitting module (30) matches a data range within the database unit (105), the main control board unit (102) sends comparison result back to the antenna unit (101), when the antenna unit (101) receives the signal, the antenna unit (101) activates or does not activate each tire pressure sensor (100) to detect and operate on each tire based on a content of the signal.
