The invention relates to the technical field of
wireless communication, and discloses an anti-interference
tire pressure sensor
pairing method for a whole vehicle
production line, which comprises the following steps: S101, sending a low-frequency instruction to a to-be-paired
tire pressure sensor through a low-frequency trigger; s102, generating unique
authentication data after the
tire pressure sensor receives the low-frequency instruction, and feeding back the unique
authentication data to the low-frequency trigger through a high-frequency
signal; s103, the low-frequency trigger extracts
signal features, and after validity and
rolling code matching are judged, secondary
authentication is carried out; generating authentication response data through the secondary random challenge code, and verifying the authentication response data; if the
verification is passed, determining that the matching is successful; s104, writing the verified tire
pressure sensor identification data into a tire
pressure detection control unit, and carrying out secondary consistency
verification; and S105, the tire
pressure detection control unit compares the high-frequency
analog signal with the tire
pressure sensor identification data, and if the result is consistent,
pairing is confirmed. According to the invention, high-reliability automatic
pairing in a
production line environment is realized.
