Embodiment Construction

[0034] As shown in Fig. 1, a kind of high electromagnetic tolerance of the present invention is used the small-sized camera of electromagnetic compatibility test, and so-called electromagnetic compatibility (EMS) refers to can provide high radiant energy tolerance (EMS) and block electromagnetic wave external radiation interference (EMI) Wait for two aspects. The physical appearance of the present invention is to cover the camera 20 (referring to FIG. 3 ) in the airtight conductive housing 10. The housing 10 can be formed by a metal material, and a conductive glass 11 is installed on one side of the housing 10, wherein, The lens of the internal camera 20 is aimed at the conductive glass 11 to take an external image. On the other side of the casing 10, a power switch 24 for controlling whether the internal camera is activated is set, and the image signal line for transmitting the shooting picture is also connected to this side. 30 and charging hole 26.

Abstract

Small type photograph device includes a camera, electrooptical signal converter, and a rechargeable battery, which are installed inside conductive case. When power is on, rechargeable battery provides operational power supply for camera to carry out work of taking photos. The electrooptical signal converter converts image data to electrooptical signal, which is transferred to outside through an optical fiber cable. Since having no other exposed conductive material, thus, the device is not interfered by electromagnetic wave from tested system. The small type photograph device can pickup monitored image clearly as well as does not generate radiation of electromagnetic wave, which will influence on measuring correctness.

Description

technical field [0001] The invention relates to a monitoring camera device used in an electromagnetic compatibility testing system, especially a camera that can clearly capture monitoring images without being interfered by electromagnetic waves of the testing system, and does not produce electromagnetic radiation that affects the accuracy of the test. Background technique [0002] In order to prevent the electronic devices on the vehicle (such as the instrument panel on the car) from malfunctioning or stalling due to electromagnetic interference when passing through an environment with high electromagnetic waves, the entire vehicle must receive various polarized electromagnetic waves during the development of the vehicle. tolerance test. This kind of electromagnetic wave test for vehicle devices such as locomotives and automobiles is generally carried out in a professional airtight laboratory. [0003] As shown in Figure 7, when a polarized electric field is applied to the ...
