Problems solved by technology

[0004] However, the existing tire detection system usually uses the vehicle battery for power supply. When the vehicle engine is turned off, the power of the vehicle battery is limited. To collect and send the tire pressure of the vehicle in real time requires the communication module to be online for a long time, and Most of the existing communication modules occupy a large bandwidth and high power consumption, so the power consumption of the host computer is also large, resulting in waste of resources, which in turn can easily lead to the loss of the vehicle battery and affect the start of the vehicle

Embodiment 1

[0053] An embodiment of the present invention provides a tire pressure monitoring system 10, such as figure 1 As shown, the tire pressure monitoring system 10 includes: a tire pressure sensor 101 , a host 102 connected to the tire pressure sensor 101 , and a client 103 wirelessly connected to the host 102 .

[0054] Wherein, the host 102 is provided with a long term evolution internet of things (LTE-Machine to Machine, LTE-M) module 1021 . The tire pressure sensor 101 is used to detect the tire pressure of the vehicle tire, and send the tire pressure to the host 102 . The host 102 is used to determine whether the tire pressure of the vehicle is abnormal; when the tire pressure of the vehicle is abnormal, the LTE-M module is used to send the tire pressure and / or an alarm to the client 103 information.

[0055] For example, assuming that the vehicle has four tires, the tire pressure monitoring system 10 may include four tire pressure sensors 101, the four tire pressure sensors 1...

Embodiment 2

[0075] An embodiment of the present invention provides a tire pressure monitoring method, which is applied to a host, and the host is provided with a long-term evolution Internet of Things LTE-M module, such as image 3 As shown, the method includes:

[0076] Step 301, acquiring tire pressure of vehicle tires.

[0077] As an example, the host computer may be connected to a tire pressure sensor provided on the tire of the vehicle, and then receive the tire pressure of the tire sent by the tire pressure sensor. Specifically, the host may be wirelessly connected to the tire pressure sensor, or may be wired to the tire pressure sensor, which is not limited in this embodiment of the present invention.

[0078] Step 302, determine whether the tire pressure of the vehicle is abnormal.

[0079] For example, the host can preset the standard tire pressure and the preset threshold. After receiving the tire pressure sent by the tire pressure sensor, it can first determine whether the di...

Embodiment 3

[0089] An embodiment of the present invention provides a tire pressure monitoring method, which is applied to a cloud server, such as Figure 4 shown, including:

[0090] Step 401, receiving the current tire pressure of the vehicle sent by the host.

[0091] Optionally, when the tire pressure of the vehicle is abnormal, the host can use the LTE-M module to send the tire pressure to the cloud server.

[0092] Step 402, receiving the vehicle model information and tire information of the current vehicle sent by the client.

[0093] For example, different types of vehicles require different normal tire pressures. Different types of tires require different normal tire pressures. Therefore, the client can obtain the vehicle model information and tire information, and send the vehicle model information and tire information to the cloud server. The cloud server can obtain the normal ranges of tire pressures of different models of vehicles given by the manufacturers, and the normal...

Abstract

The embodiment of the invention discloses a tire pressure monitoring system which comprises a tire pressure sensor, a main machine connected to the tire pressure sensor and a client wirelessly connected to the main machine. The main machine is provided with a long term evolution Internet of things LTE-M module; the tire pressure sensor is used for detecting the tire pressure of a vehicle tire and sends the tire pressure to the main machine; the main machine is used for determining whether the tire pressure of the vehicle is abnormal or not; and when the tire pressure of the vehicle is abnormal, the LTE-M module sends the tire pressure and / or alarm information to the client. Furthermore, the embodiment of the invention also discloses a tire pressure monitoring method applied to the main machine and a tire pressure monitoring method applied to a cloud server.

Description

technical field [0001] The invention relates to tire pressure detection technology in the field of automobile control, in particular to a tire pressure monitoring system and method. Background technique [0002] With the improvement of people's living standards, the penetration rate of cars is getting higher and higher. The convenience and quickness of the car has made it the preferred means of transportation for people to travel. In practical applications, automobiles usually use pneumatic tires, and tire pressure is an important parameter for pneumatic tires to ensure the safety and comfort of vehicles. [0003] In the prior art, in order to ensure the driving safety and comfort of the vehicle, it is necessary to detect the tire pressure of the tire in real time. Specifically, a tire pressure sensor can be set on the tire of the vehicle, and the tire pressure of the vehicle tire can be collected in real time, and then the collected tire pressure can be sent to a host com...
