[0034] The test process includes: turn on the driving device, drive the tire to rotate at high speed through the transmission device; the tire rotates to activate the tire pressure sensor; the tire pressure sensor acquires the tire sensing data and transmits the wireless signal carrying the tire sensing data every predetermin...

specific Embodiment 2

[0046] Such as figure 2 As shown, the embodiment of the present invention provides a method for testing a tire monitoring system, including:

[0047] Initial placement step S101:

[0048] Place the tire pressure monitoring system so that the distance from the tire pressure sensor is a predetermined distance;

[0049] Test step S102:

[0050] Turn on the driving device, drive the tire to rotate at high speed through the transmission device; the tire rotates to activate the tire pressure sensor; the tire pressure sensor acquires the tire sensing data and transmits the wireless signal carrying the tire sensing data every predetermined cycle, and increases the number of sending signals by 1 at the same time ; The tire pressure monitoring system receives the wireless signal and increases the number of received signals by 1; counts the number of times of sending signals and times of receiving signals within the predetermined test time;

[0051] Maximum stable receiving distance ...

Abstract

The invention discloses a test system and method of a tyre monitoring system. A tyre pressure sensor is installed on an automobile tyre, and the automobile tyre is installed on a stationary work table; a driver drives the tyre to run, and the tyre pressure sensor is activated, sends tyre pressure and temperature signals and communicates with a tyre pressure monitoring system; and the frequency inwhich the tyre pressure sensor sends the signals and the frequency in which the tyre pressure monitoring system receives the signals within predetermined test time are calculated, and a distance between the tyre pressure monitoring system and the tyre pressure sensor is determined according to a difference between the signal sending frequency and the signal receiving frequency. A test process needs not to be carried out in an automobile driving state, positions of the automobile tyre and the tyre pressure sensor are fixed and the position of the tyre pressure monitoring system is not fixed sothat the distance between the tyre pressure monitoring system and the tyre pressure sensor is not limited by a vehicle body any longer, the position of the tyre pressure monitoring system can be changed at will, and whether a communication distance between the tyre pressure sensor and the tyre pressure monitoring system belongs to a stable reception distance is tested.

Description

technical field [0001] The invention relates to the technical field of tire monitoring, in particular to a testing system and method of a tire monitoring system. Background technique [0002] In modern society, in order to ensure the safety of vehicles while driving, there is a need to monitor tire pressure, but whether the tire monitoring system can provide timely feedback of tire pressure and other data requires further testing of the tire monitoring system. Under the prior art, for the test of the function of the automobile tire pressure monitoring system and the pressure sensor, the method usually adopted in the test process is: the tire pressure sensor is installed on the automobile tire, and the sensor installed on the tire is activated during driving. , Send signals such as tire pressure and temperature, and communicate with monitoring systems installed on or near the instrument panel. The disadvantage of this test method is that the distance between the monitoring s...
