A motion platform of a pass-through metal detection door testing device

Abstract

The invention provides a motion platform of a pass-type metal detection door test device. The motion platform is made of plastic and driven by a synchronous belt to slide on a test guide rail of the test device, the synchronous belt is a belt of which the outer side is a smooth surface and the inner side is a tooth surface, and the motion platform comprises an upper shell, a lower shell, a guide rail fixing base and a synchronous belt clamping block.

Description

technical field [0001] The invention relates to the testing field of security inspection equipment, and more particularly relates to a test device for a pass-through metal detection door and a motion platform thereof. Background technique [0002] Pass-through metal detection doors are widely used in personal security inspections in airports, railways, prisons, large-scale events and other places. The through-type metal detection door presets a uniform magnetic field in the passage area. If the person passing through the passage carries metal on his body, it will disrupt the original magnetic field distribution and cause an alarm. The application of such equipment can effectively prevent metal contraband from entering specific areas through personal carrying, and is an important means of ensuring safety. [0003] The detection performance of the pass-through metal detection door directly determines the detection rate of metal contraband carried by people. For the test of d...

Problems solved by technology

Due to the increasing number of people wearing glasses, porcelain teeth, metal brackets and joints, the selection range of standard testers is getting narrower

Moreover, due to the wide range of height and weight requirements for standard testers, it was found in the actual test that standard testers of different shapes have a slight impact on the internal magnetic field of the pass-through metal detection door, which may cause inaccurate test results

[0005] 2. The range of passing speed stipulated in the national standard should not be less than 0.4m / s~1.8m / s. In the actual test, it is difficult for the standard tester to maintain a specific passing speed.

[0006] 3. The national standard stipulates 12 positions that need to be tested in the detection plane of the pass-through metal detector door. The positioning error of each position is required to be within 50mm. In the actual test, the standard tester's body shape and gait are different, so it is difficult to guarantee carrying Position accuracy of the test object

[0007] 4. According to the test items stipulated in the national standard, all tests on a single pass-through metal detection door require at least a standard tester to turn back and travel a distance of more than 3 kilometers. Location, alarm information, this manual testing method is time-consuming, heavy workload, poor accuracy and repeatability
