Description
Technical field
The utility model relates to Electromagnetic Testing Technology field, particularly relates to a kind of multifunction electromagnetic compatibility test laboratory.
Background technology
When equipment be in normally work in the environment of a certain opening time, we generally expect that equipment can not because the disturbing effect of other equipment normally works, simultaneously also can not to except he itself except other equipment have an impact, this impact and the situation be affected, be called the Electro Magnetic Compatibility of electrical appliances product.Along with the development of science and technology, increasing electronics, electrical equipment enter the every field that we live and produce, these equipment also outside radiated electromagnetic energy while normal operation, may exert an adverse impact to other equipment, even cause serious harm, according to statistics, spatial electromagnetic energy in the whole world increases 7-14% every year on average.Under limited space and limited frequency resource condition, due to various electronics, the quantity of electrical equipment grows with each passing day, and the dense degree of use is increasing, and the seriousness of electromagnetic interference (EMI) is just more and more outstanding.
Radiation disturbance and radiation anti-interference be important content in electromagnetic compatibility test be also the project the most easily pinpointed the problems in test and least easily pass through, the place being above standard and requiring is found that there is in its test, rectification is just inevitable, but two test sites require different, test circumferential arrangement is different, sample is repeatedly tested in two different test environments, the early stage wasting product unavoidably researches and develops the time, for waste enterprise with delay business opportunity, for test laboratory, reduce test and work efficiency.
Concrete, radiation disturbance and the jamproof test of radiation both can be tested at fully anechoic chamber, also can test at semi-anechoic chamber, but it is common, major part company is all (bottom does not need to lay suction ripple material) test (30MHz-1G) in semi-anechoic chamber, but must test in fully anechoic chamber (bottom needs all to lay to inhale ripple material) at more than 1G, and the anti-interference test of radio frequency electromagnetic field radiation (RS) is in semi-anechoic chamber test, only needs to lay sub-fraction in the middle of antenna tower 21 and test desk and inhale ripple material.Obviously, two important content radiation disturbances of electromagnetic compatibility test have similar and not identical requirement condition with the jamproof test of radiation in different radio frequency bands requires.
Shown in accompanying drawings 1, for carrying out the schematic diagram of RS test in semi-anechoic chamber in prior art.Be mounted with the non-conductive bearing 29 of Flied emission antenna tower 21 and 0.8 meter high in 2 by 3 meters, test request interval (L in diagram) between the test in laboratory, non-conductive bearing 29 is mounted with EUT (test product), be mounted with the surveying instrument 11 of Device under test in the operation room 1 in laboratory and produce the equipment 12 of field, wave filter 13 is through walls to be entered in test and to be electrically connected with EUT22 phase by connecting for surveying instrument 11, the equipment 12 producing field intensity to be entered between test in 2 by cable 14 through walls and is electrically connected mutually with Flied emission antenna tower 21, EUT22 is electrically connected mutually with the input power wave filter 23 be arranged between test on 2 walls, in order to provide power supply to EUT22.And shown carry out in the schematic diagram of RS test, floor between emitting antenna tower 21 on the scene and non-conductive bearing 29 is mounted with one piece of absorbing material 24, in order to reduce the reflection on floor, and compared with the condition of EMC emission test, difference is only the absorbing material 24 do not had shown in figure, and bottom surface is entirely the metal shield of standard configuration, as the reference metal face 25 that content measurement is analyzed.
Again by reference to the accompanying drawings shown in 2, operating diagram during for carrying out EMC emission test in semi-anechoic chamber in prior art in test.The direct wave 26 that EUT22 receiving antenna tower 21 sends and the reflection wave 27 after reference metal face 25 is reflected are tested, and accordingly, for the RS test in such as accompanying drawing 1, then reflection wave is partially absorbed by absorbing material 24, reaches the effect reducing floor reflection ripple., it is worthy of note, in the laboratory test that two kinds of tests match, except floor, other faces (metope and ceiling) is all furnished with absorbing material meanwhile.And two kinds of content measurements include: 1) test duration should not be less than equipment under test operation and the time needed for reaction; 2) horizontal and vertical poliarizing antenna is adopted to carry out the test in 4 faces in the place of 3 meters, distance test sample (EUT22 be namely electrically connected mutually).
Therefore, demand one can carry out the multifunction electromagnetic compatibility test laboratory of multiple content measurement (comprising radiation disturbance and the anti-interference test of radiation), solves the problem needing sample testing wheel fallback repeatedly in two different test environments because two test site requirements are different and test circumferential arrangement different.
