Description
Technical Field
The invention relates to the technical field of simulation test, in particular to a tire pressure chip testing device and a tire pressure chip testing system.
Background
The national standards administration committee issued "performance requirements and test methods for passenger vehicle tire pressure monitoring systems" on day 10 and 14 of 2017. The method specifies that the vehicle should install the TPMS required by the specification as follows:
(a) For passenger cars with an in-engine and an aspect ratio of less than or equal to 0.9, a new application type approval vehicle model is started from 1 st 2020, and a vehicle model for which a type approval has been obtained is started from 1 st 2021.
(b) For other M1 class vehicles, new application type approval vehicle models are implemented from 1 st 2019, and the obtained type approval vehicle models are implemented from 1 st 2020.
Therefore, the testing according to the vehicle standard is particularly important for TPMS and TPMS chip manufacturers. One of these concerns is critical with respect to the testing for simulating tire leakage. This requires that the sensor must send out early warning signals in time when the tire bursts and cannot affect signal emission and malfunction under high airflow.
At home, the current TPMS manufacturers rely on centrifuges (devices for acceleration calibration testing) for testing. The disadvantages are two: one is that the equipment is expensive, and the other is that the centrifuge can not simulate the tire burst environment.
