Abstract

A self-programming tyre pressure monitoring device and an implementation method therefor. The implementation method for the self-programming tyre pressure monitoring device comprises: pre-storing a plurality of format codes, and selecting corresponding format codes according to guidance codes generated by a self-programming tyre pressure monitoring device. The self-programming tyre pressure monitoring device comprises: a code input and code indication unit (5) for generating guidance codes and indicating guidance codes being chosen; a microcontroller unit (3) for pre-storing a plurality of format codes, and selecting corresponding format codes according to the guidance codes; a radio-frequency transmission unit (2) for sending data from the microcontroller unit (3) at a given radio frequency; and a sensor unit (4) for collecting external data, and sending the collected external data to the microcontroller unit (3). The self-programming tyre pressure monitoring device and implementation method therefor do not need external tools, so that the operation is simple; only a few data packets are sent each time, so that the service life of a battery can be greatly prolonged; and more formats and contents can be stored, so that the inventory of vendors is significantly reduced.
