Embodiment Construction

[0027] Embodiments of the present invention relate to managing the sensors of the TPMS system through mobile phones, especially smart phones with higher processing capabilities. The management functions may include tire information (such as tire internal temperature, pressure, acceleration, etc.) monitoring, sensor detection and Re-identification, sensor program update, etc. Due to the ubiquity of mobile phones, there are many advantages to performing the above functions through mobile phones rather than dedicated sensor detection tools. These advantages will be described through the following embodiments with reference to the accompanying drawings.

[0028] figure 1 A structural block diagram of a TPMS according to an embodiment of the present invention is shown. refer to figure 1 As shown, the TPMS system 100 may include a sensor 130, a receiver 140, and a display device not shown in the figure. In this embodiment, the TPMS system 100 may include a mobile phone 110 . A ...

Abstract

The invention relates to a tire pressure monitoring system and a sensor management method. The tire pressure monitoring system comprises a sensor and a receiver. In the sensor management method, a portable tool is used, for instance, a mobile phone serves as a platform, and a sensor management program is loaded in and operated to monitor the sensor and update programs of the sensor. In a tire information monitoring flow, a command for obtaining tire information is sent to a transition module through a wired or wireless channel of the mobile phone; and the transition module returns the tire information back to the mobile phone through the wired or wireless channel after obtaining the tire information from the sensor. In a sensor program updating flow, a new sensor program is received through a mobile communication channel of the mobile phone and is transmitted to the sensor through the transition module, so that the sensor program is updated in at least one sensor. Compared with the former way utilizing a special sensor detecting tool, the management method is more flexible in operation and facilitates the observation, the classification and the analysis of tire pressure data.

Description

technical field [0001] The invention relates to a tire pressure monitoring system (TPMS), in particular to the technology of sensor monitoring and program updating by using a mobile phone. Background technique [0002] TPMS has a decisive impact on improving car safety, and tires are the only part of the car that is in direct contact with the road. Tires that are over-inflated or under-inflated can affect vehicle safety. Many car accidents are caused by the condition of tires. The current TPMS is mainly composed of four parts: sensor, receiver, display device and sensor detection tool. Vehicle drivers mostly use three parts: sensors, receivers, and display devices. The sensor detects information such as tire temperature, pressure, acceleration, etc., and then sends it to the receiver through RF high-frequency data signals. The receiver can transmit these to the display device, and the user can understand the tire pressure information through the information displayed by ...
