Automatic matching tire pressure sensor information system based on production line

The utility model relates to an automatic matching tire pressure sensor information system based on a production line. By adopting the automatic matching tire pressure sensor information system, in an automobile production line, an automobile is driven to an appointed position, a corresponding communication interface is connected with an interface on the automobile, and then position information of a tire sensor can be set by operating a controller. The automatic matching tire pressure sensor information system based on the production line comprises a controller and triggers, wherein a plurality of the triggers are arranged on specific stations of the production line, the position of each trigger corresponds to the position of each tire of an entire automobile, and each trigger is connected with an LIN bus interface of the controller; the controller performs low-frequency triggering by controlling the triggers so as to control a sensor in a position dead against each trigger in a tire to send out a sensor ID code and position information of the sensor; a CAN (controller area network) communication interface of the controller is connected with a vehicle-mounted CAN bus; and the ID code and position information of each sensor stored by the controller are transmitted to a vehicle-mounted body controller for storage through the CAN bus.
