Embodiment approach

[0056] According to an embodiment of the present invention, the data transmission method of the tire pressure sensor further includes: updating the stored tire-related information.

[0057] That is, in the case that the second predetermined transmission mode transmits the current tire-related information, the stored tire-related information can be updated (that is, the acquired current tire-related information can be used to replace the previously stored tire-related information as the newly stored tire-related information). relevant information, the newly stored tire-related information can be used for the determination of the next tire pressure sensor data transmission mode), at this time, the entire content of the acquired current tire-related information is stored in the memory; and in the first scheduled transmission When the current tire-related information is sent in the mode, the stored tire-related information is not updated, and its content remains unchanged.

Abstract

The invention relates to the technical field of tyre pressure sensing, and provides a data transmission method and system of a tyre pressure sensor. The method includes initializing the tyre pressuresensor; acquiring current tyre-related information from the tyre pressure sensor; comparing the acquired current tyre-related information with stored tyre related information after a preset time period; and determining a transmission mode for transmitting the current tyre-related information according to the comparison result. The method and the system can determine the corresponding information transmission mode according to the specific current tyre-related information, and therefore the using efficiency of a battery of the tyre pressure sensor can be increased under the premise of not sacrificing system timeliness or stability, thus prolonging the service lifetime.

Description

technical field [0001] The invention relates to the technical field of tire pressure sensing, in particular to a data transmission method and system of a tire pressure sensor. Background technique [0002] The tire pressure monitoring system (TPMS, Tire Pressure Monitoring System) refers to an auxiliary system installed on the vehicle that can monitor the tire pressure in a certain way and give an alarm when the tire is abnormal. The system mainly consists of three parts: tire pressure monitoring module, receiver module and display module. At present, the direct one-way tire pressure monitoring system is mainly used in the existing technology, that is, the tire pressure sensor is installed inside the tire to monitor the tire status information in real time and send it periodically. The tire pressure receiver module receives the information and performs data processing to notify Display modules. [0003] According to whether battery power is required, sensors are usually di...
