specific Embodiment approach
[0053] In order to clearly and completely describe the technical solution of the present invention and its specific working process, in conjunction with the accompanying drawings, the specific implementation of the present invention is as follows:
[0054]In the present invention, unless otherwise clearly specified and limited, terms such as "installation", "connection", "connection" and "fixation" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection , or integrated; it may be mechanically connected or electrically connected; it may be directly connected or indirectly connected through an intermediary, and it may be the internal communication of two components or the interaction relationship between two components, unless otherwise specified limit. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention according to specific situations.
[0055] In the present in...
Embodiment 1
[0058] The first embodiment discloses a 5G signal-based electromagnetic immunity test system for vehicle-mounted wireless communication products, including: 5G signal generation module, 5G signal processing module, 5G signal transmission module, function monitoring and verification module, electromagnetic interference module and 5G Communication test module.
[0059] Such as figure 1 As shown, the 5G signal generation module is composed of a 5G comprehensive tester 4, the model of the 5G comprehensive tester 4 is: R&SCMX500, and the 5G comprehensive tester 4 is set inside the laboratory and outside the dark room 1. It is used to generate the 5G frequency band signal required by the tested vehicle wireless communication product in the dark room 1; and send the generated 5G frequency band signal to the 5G signal processing module.
[0060] Such as figure 1 As shown, the 5G signal processing module is arranged outside the darkroom 1, and is composed of a signal amplifier 5 and ...
Embodiment 2
[0072] The second embodiment discloses a 5G signal-based electromagnetic immunity test method for vehicle-mounted wireless communication products. The test method is implemented by the electromagnetic immunity test system for vehicle-mounted wireless communication products based on 5G signals described in the first embodiment, as follows: figure 2 As shown, the specific steps of the test method are as follows:
[0073] Step S1: Simulate and transmit 5G signals outside the anechoic chamber and ensure that the 5G signal reception in the anechoic chamber is normal;
[0074] The specific process of this step S1 is as follows:
[0075] First, according to the test system described in Embodiment 1, according to the 5G communication frequency band of the product to be tested, the 5G comprehensive tester is used to generate a 5G signal of the corresponding frequency, and the built-in software of the host computer is used to query the signal generated by the 5G comprehensive tester, a...
