Temperature-humidity-electromagnetism integrated environment simulation device

Abstract

The present invention belongs to the detection equipment field of the electronic equipment, in particular relates to a temperature-humidity-electromagnetism integrated environment simulation device. The temperature-humidity-electromagnetism integrated environment simulation device comprises an environment test room in which an electromagnetic reverberation chamber is arranged, and a ventilation structure used for ventilating and capable of keeping the original shielding efficiency of the reverberation chamber is arranged on a wall of the electromagnetic reverberation chamber. An electromagnetic interference test environment is provided in the electromagnetic reverberation chamber with the ventilation structure, and the electromagnetic reverberation chamber is not interfered by an external electromagnetic environment. The environment test room is used to adjust the temperature and humidity of the own internal space, and also transmit the relevant temperature and humidity change to the internal space of the electromagnetic reverberation chamber via the connection action of the ventilation structure, thereby changing the temperature and humidity in the electromagnetic reverberation chamber. By the above structure, various tests can be carried out on a same device, various extreme environments of the electronic equipment can be simulated more really, at the same time, the test time is shortened, and the consumption of the manpower and material resources is reduced.

Description

technical field [0001] The invention belongs to the field of detection equipment for electronic equipment, in particular to a temperature-humidity-electromagnetic comprehensive environment simulation equipment. Background technique [0002] At present, the environment in which electronic equipment is located is becoming more and more complex. Electronic equipment often works in complex environments such as extreme temperature, extreme humidity, and electromagnetic interference. These interference factors will affect the performance of electronic equipment. For this reason, current electronic equipment needs to pass various environmental tests before being designed and shipped. [0003] The electromagnetic reverberation chamber is equipped with an antenna and a mechanical electromagnetic stirrer in a high-Q shielding shell. The antenna generates radio frequency electromagnetic signals. The electromagnetic wave is reflected back and forth by the wall and the electromagnetic st...

Problems solved by technology

Completing these tests one by one requires a lot of testing time and manpower; at the same time, because each test is carried out separately, it is impossible to comprehensively consider the interaction and synergy between the test factors, which also makes the final test results may be different from the actual ones. The big difference makes the electronic equipment leaving the factory hidden dangers

[0006] So, is it possible to create a same space that can provide both electromagnetic interference test environment and temperature and humidity test environment? Experiments have found that if a temperature and humidity adjustment device is installed in the electromagnetic reverberation room, the existence of the temperature and humidity adjustment device will have a certain impact on the electromagnetic waves, which will cause a certain deviation in the simulation effect of the electromagnetic reverberation in the electromagnetic reverberation room.

For this reason, prior art also has to make improvement, a kind of comprehensive test device that is used for environmental test disclosed as Chinese utility model patent CN205374636U, and this device installs high and low temperature test box on one side of electromagnetic microwave shielding dark box, makes high and low temperature Most of the parts of the test box are located outside the reverberation space of the electromagnetic microwave shielding dark box, while the surfaces of the other sides are provided with a layer of absorbing material, but there is no absorbing material at the air inlet and outlet of the high and low temperature test box This will obviously have a certain impact on the electromagnetic wave shielding effectiveness of the electromagnetic microwave shielding obscura, and then affect the reverberation effect of the electromagnetic microwave shielding obscura
