Embodiment Construction

[0018] As shown in Figure 1, in the embodiment of the tire pressure measurement system of the present invention, the tire pressure measurement system includes a tire positioning device 1, a monitoring host 2, four tire pressure sensor modules 3 respectively installed inside four tires, and an installation Two high-frequency antennas 4 at the front and rear of the vehicle. When the tire needs to be positioned, for example, when the vehicle is assembled on the production line or the tire needs to be replaced after the vehicle is sold, the tire positioning device 1 is placed close to one of the above four tires, and the button on the tire positioning device 1 is pressed. The tire positioning device 1 sends a low-frequency signal to activate the tire pressure sensor module 3 in the tire it is close to. The tire pressure sensor module 3 initializes and sends out its own identification code through a high-frequency signal. The tire positioning device 1 After receiving the high-frequ...

Abstract

The invention relates to a tyre pressure measuring system, which comprises pressure sensor (3), pressure detector (2), and positioning device (1), wherein the positioning device 91) activates the sensor (3), records its recognize code and sends the recognize code to the detector (2); when it activates or records the sensor (3) or its recognize code, the positioning device (1) will approach the module; when it transmits recorded data to the detector (2), the positioning device (1) and the detector (2) are connected via bus interface. The invention can reduce cost and interference.

Description

technical field [0001] The present invention relates to measurement systems, and more particularly, to a tire pressure measurement system. Background technique [0002] Vehicle tire pressure measurement systems have become more and more widely used in existing vehicles and have become mandatory standards in the United States. The current situation is that the tire pressure sensor module has been installed on the tire of the car when it leaves the factory, but due to its particularity, it is required that the tire pressure sensor module is in a power-off state when the tire is not in use. When assembling on the production line or changing tires while the car is in use, it is necessary to activate the tire pressure sensor module in the tire and send its identification code to the monitoring host in the car, so that the monitoring host can identify the signal sent by the tire pressure sensor module. Which tire pressure sensor module sends out and displays on the display device...
