Shielding chamber of pull-inserting type replacement test system

Abstract

The invention provides a shielding chamber of a pull-inserting type replacement test system. The shielding chamber comprises a shielding room, a motor set and a control module arranged outside the shielding room, wherein the shielding room comprises four side surfaces, a top surface and a bottom surface, a first square notch arranged in one end, close to one side face, of the bottom face, a secondsquare notch formed in the side face above the first square notch, a moving surface which is arranged on the first square notch and matched with the size of the first square notch, a shielding wall arranged at the junction of the moving surface and the second square notch and a conveying device arranged below the moving surface. A testing platform and auxiliary testing equipment on the moving surface can be moved out of the shielding chamber through the conveying device to replace a testing system. According to the shielding chamber of a pull-inserting type replacement test system, the test system can be rapidly replaced after electromagnetic measurement is finished, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of electromagnetic compatibility testing, in particular to a shielding room of a plug-in replacement testing system. Background technique [0002] Electromagnetic Compatibility (EMC) refers to the ability of a device or system to operate satisfactorily in its electromagnetic environment without causing intolerable electromagnetic interference to any device in its environment. Therefore, EMC includes two requirements: on the one hand, it means that the electromagnetic interference generated by the equipment during normal operation cannot exceed a certain limit; on the other hand, it means that the equipment has a certain Degree of immunity, that is, electromagnetic susceptibility. [0003] The shielding room is an important test site for measuring the radiation interference and radiation immunity of the equipment under test. It is mainly used to reduce the interference of the external electromagnetic wave signal on th...

Problems solved by technology

[0003] The shielding room is an important test site for measuring the radiation interference and radiation immunity of the equipment under test. It is mainly used to reduce the interference of the external electromagnetic wave signal on the test signal, and the test system is used to transmit the signal during the test. Different test requirements require different type of test system, the existing way to replace the test system in the shielded room is usually manual disassembly and replacement, which is cumbersome and time-consuming. Therefore, it is necessary to provide a shielded room that can quickly replace the test system, which can ensure that the shielded room In the case of excellent shielding performance, the rapid replacement of the test system can be realized to ensure the effective progress of the test work
