LIN communication technology-based double-host tire pressure monitoring system

The invention provides an LIN communication technology-based double-host tire pressure monitoring system. The system comprises a display or a controller, a first relay host, a second relay host, and a plurality of tire pressure sensors which are respectively in matched connection with the first relay host and the second relay host, and the first relay host and the second relay host respectively comprise an LIN module, and are connected with the display or the controller through LIN buses. The system has the following advantages: double hosts are arranged to guarantee the acquisition timeliness and accuracy of a sensing signal; and an LIN communication technology is used to make the display support the double relay hosts, so low cost and interference resistance are realized, and a problem of difficult accurate feedback in traditional schemes is well solved.
