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

Embodiment Construction
[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0023] Such as figure 1 As shown, the structure of the through-type metal detection door testing device of the present invention mainly includes: a cantilever mechanism 1 , a test body transmission mechanism 2 , a motion platform 3 , a control display unit 4 , a frame, and a casing 6 .
[0024] Such as figure 2 As shown, the cantilever mechanism 1 includes a cantilever rod 11, a cantilever rod holder 12, a cantilever bearing 13, a flexible chain 14, a cantilever counterweight assembly 15, two cantilever pulleys 161, 162, a tee holder 17, and a tension wire 18. The cantilever mechanism 1 is located on the upper part of the entire testing device, and is used to maintain the levelness of the Y-axis guide rail 222 on which the motion platform 3 is installed. The cantilever rod 11 is a hollow steel pipe with good rigidity, and cantileve...

The invention provides a pass-type metal detection test device. The pass-type metal detection door test device comprises a cantilever mechanism, a test body transmission mechanism, a motion platform, a control display unit, a frame and a shell. The test body transmission mechanism comprises an X-axis transmission assembly, a Y-axis transmission assembly and a Z-axis transmission assembly, wherein the Y-axis transmission assembly is provided with a Y-axis guide rail, and the motion platform passes through and slides on the Y-axis guide rail under the joint action of the X-axis transmission assembly, the Y-axis transmission assembly and the Z-axis transmission assembly. The test device can make detection operation easily, conveniently and virtually conducted, and the test process is automatic and intelligent.
Description
technical field [0001] The invention relates to the testing field of security inspection equipment, and more particularly relates to a testing device for a pass-through metal detection door. 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 detection performance, the m...
