Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile TBOX testing, and particularly relates to a field controller reverberation chamber for automobile TBOX testing. BACKGROUND

[0002] An automobile is a vehicle that is powered by any means other than muscular energy and has four or more wheels, and is designed for travel on land rather than on rails or tracks. The main functions of an automobile include: carrying passengers and cargo, towing vehicles carrying passengers and / or cargo, and completing specific transportation or work tasks. Due to its versatility, the automobile has become an indispensable part of modern society. Its design not only takes into account basic driving performance, but also includes a variety of safety and comfort features. Automobiles are classified in various ways, mainly into passenger cars and cargo trucks, as well as special-purpose vehicles designed to perform specific tasks. These special-purpose vehicles can include fire engines, ambulances, police cars, etc.

[0003] The automobile TBOX is an important part of the vehicle Internet of Things system of an automobile, and it is an intelligent vehicle terminal device. It realizes communication and data exchange between vehicles, between vehicles and infrastructure, and between vehicles and the Internet through a processor, a GPS module, a 4G / 5G module, and various interfaces. In the production process of the automobile TBOX, pre-delivery function testing of the automobile TBOX is an indispensable part, which tests whether various signal transceiving functions are normal. Only the automobile TBOX that passes all function tests can be qualified for delivery. The most common testing method is to use a field controller reverberation chamber for testing. The field controller reverberation chamber is a special test system used to create a diffusion field for testing. The reverberation chamber has the characteristics of very small signal absorption and very long reverberation time. The indoor signal is uniformly distributed after multiple reflections to form a signal field.

[0004] At present, since the automobile TBOX has many functional modules, including a GPS module, a 4G / 5G module, a Bluetooth module, a WiFi module, an FM module, and various functional modules, different signal transceiving tests need to be performed. The signal direction of each functional module is different, and the coupling antenna array direction of signals of different frequency bands is also different. Therefore, different coupling antenna arrays need to be set in different directions of the field controller reverberation chamber according to the signal type and frequency band. Therefore, in the existing production link, different field controller reverberation chambers are generally used to separately test the GPS module, the 4G / 5G module, the Bluetooth module, the WiFi module, the FM module, the radio frequency module, and various functional modules. This testing method requires a large number of field controller reverberation chambers, which not only consumes a large amount of manpower and resources, but also has high testing costs, a long testing period, low testing efficiency, and inconsistent testing quality, which is difficult to meet people's production needs.
