Problems solved by technology

[0005] However, the prior art described above cannot be performed automatically and must be done manually
It is time-consuming to deflate and re-inflate the tires one by one, and every time a new tire is replaced or the position of the tire is changed, the position of the tire condition sensing device has to be re-identified, so the existing technology is quite inefficient and time-consuming. , unable to meet the needs of consumers

Embodiment Construction

[0033] The feature of the present invention is that when it is determined that a tire state sensing device is transmitting a signal, the antenna is quickly switched on and off in turn, and multiple signal strength change values ​​are obtained, wherein the position of the antenna that produces the maximum value of these signal strength change values ​​is, is the position corresponding to the tire condition sensing device that is transmitting the signal.

[0034] The present invention can be applied as figure 1 The tire monitoring system shown, the following uses only figure 1 The positioning method of the tire condition sensing device of the present invention will be briefly described. However, the present invention is not limited to this example, and the present invention is applicable to any means of transportation (such as automobiles, motorcycles, etc.) having any number of tires (including spare tires).

[0035] refer to figure 1 and figure 2 , figure 2 It is a sign...

Abstract

The positioning method for tire sate sensors is used in identifying the positions of tire sate sensors mounted on the transportation means. All the antennas in the transportation means are first kept in on state so as to receive and decode the signal one of the tire sate sensors under monitoring emits to obtain signal strength. After determining one of the tire sate sensors in emitting signal, the antennas are made to on and off quickly in turn to obtain several varying signal strength value, and the tire corresponding to the antenna to emit the maximum signal strength change is determined as the tire the tire sate sensor emitting signal is in.

Description

technical field [0001] The present invention relates to a locating method of a tire condition sensing device, in particular to a locating method capable of automatically identifying the locations of multiple tire condition sensing devices within a short period of time. Background technique [0002] Insufficient tire pressure in car tires will cause inconvenience in driving, such as more fuel consumption, affect the handling of the car, and reduce the durability and tread life of the tire. Severe cases cause car tires to blow out, endangering the lives of passengers. The tire monitoring system can help the driver check the condition of the vehicle tires at any time in the car, such as: tire pressure, temperature, etc., thus effectively increasing the safety of the vehicle. [0003] Please refer to figure 1 , which is a structural schematic diagram of an existing tire monitoring system. Wherein, the tire state sensing devices 12, 14, 16 and 18 are respectively installed in ...
