Embodiment 1

[0034] Embodiment 1 of the present invention proposes a tire pressure monitoring method. like figure 1 As shown, the method of Embodiment 1 of the present invention includes the following steps:

[0035] S1. Collect fetal monitoring data in the current state mode. Embodiment 1 of the present invention can collect tire monitoring data through MCU, install pressure sensor, temperature sensor and acceleration sensor on the tire, collect the tire pressure, temperature and acceleration on the tire and feed it back to MCU. The MCU controls the collection, processing and sending of the aforementioned fetal monitoring data.

[0036] S2. Switch the state mode according to the collected fetal monitoring data.

[0037] Embodiment 1 of the present invention pre-divides the following various state modes according to differences in tire pressure, temperature and acceleration. In different state modes, different data collection and transmission methods are adopted. like figure 2 As sho...

Embodiment 2

[0045] Embodiment 2 of the present invention provides a tire pressure monitoring device. like image 3 As shown, the device according to Embodiment 2 of the present invention includes an acquisition module 10 and a switching module 20, wherein,

[0046] The collection module 10 is used for collecting fetal monitoring data in the current state mode. The acquisition module 10 of the second embodiment of the present invention can be an MCU, and a pressure sensor, a temperature sensor and an acceleration sensor are arranged on the tire, and the acquisition module 10 collects the tire pressure, temperature and acceleration on the tire through the above-mentioned sensors and controls the above-mentioned tire monitoring data processing and sending etc.

[0047] The switching module 20 is used for switching the state mode according to the collected fetal monitoring data. Embodiment 2 of the present invention pre-divides the following various state modes according to differences in ...

Abstract

The invention is applicable in the field of communications and provides a method and a device for tire pressure monitoring. The method comprises the following steps: tire pressure monitoring data is collected in a current state; the state model is switched according to the collected tire pressure monitoring data. According to the method and the device provided by the invention, the validity, reliability and accuracy of the tire pressure monitoring are guaranteed; simultaneously, the power dissipation is effectively reduced; the service life of a battery is prolonged.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a tire pressure monitoring method and device. Background technique [0002] The main function of the tire pressure monitoring system is to monitor, display and confirm the working status of the tires, and timely alarm the abnormal conditions of the tires (such as overpressure, underpressure, overtemperature, sudden changes in air pressure, etc.), and display the current pressure through sound, light and numbers. To ensure driving safety, prevent tire blowouts, and ensure that car tires are in a reasonable state of use for a long time. According to statistics, 70% of traffic accidents on expressways in China are caused by blown tires, while in the United States this proportion is as high as 80%. Therefore, tire pressure monitoring systems are receiving more and more attention. [0003] At present, in order to reduce the power consumption of the tire pressure sensing device, ...
