As shown in Figure 1, safety check door comprises metal detection subsystem 31 and drug/exploder detection subsystem 30, wherein drug/exploder detection subsystem 30 is in series arranged on the entrance of metal detection subsystem 31, thereby forms a complete safety check door.Certainly, drug/exploder detection subsystem 30 is also in series arranged in the outlet of metal detection subsystem 31.
As shown in Figure 1, on the top of the porch of metal detection subsystem 31, be provided with pilot lamp 25, this pilot lamp 25 is used to indicate and is examined pedestrian's several states of living in: in checking (amber light); Idle (green light); Report to the police by (red light).
As shown in Figure 1, on the outside surface of drug/exploder detection subsystem 30, be provided with the display as user terminal, for showing testing result.
As shown in Figure 1, the metal detection subsystem 31 in the present invention is by emitting electromagnetic wave, to survey the detection system of metal material, and it can adopt any metal detecting system applicable in prior art.The explanation of therefore omitting the concrete structure of metal detection subsystem 31 herein.
Together with metal detection subsystem 31 adjoins each other with drug/exploder detection subsystem 30, so many metal parts (such as metal shell, metal pipe line etc.) in drug/exploder detection subsystem 30, can cause interference to metal detection subsystem 31, have a strong impact on the result of detection of metal detection subsystem 31.Particularly, when 31 work of metal detection subsystem, the electromagnetic wave of its transmitting will inevitably be diffused on the above-mentioned metal parts of drug/exploder detection subsystem 30, then turns back in metal detection subsystem 31, so just causes metal detection subsystem 31 to occur wrong report.
And, owing to also there being many Electromagnetic Interference source (such as compressor, blower fan, solenoid valve etc.) in drug/exploder detection subsystem 30, therefore the electromagnetic wave going out of these Electromagnetic Interference source transmittings can enter in metal detection subsystem 31 equally, and metal detection subsystem 31 is produced and disturbed.

On the other hand, because the various signal wires of metal detection subsystem 31 and drug/exploder detection subsystem 30 all must be connected to overhead control cabinet 14, therefore between two subsystems, be easy to occur signal cross-talk.
Between two subsystems, there is signal cross-talk, as shown in Figure 6, the controller 22 of metal detection subsystem 31 is first connected with signal isolator 10 (corresponding to the another kind of spacer assembly in the present invention) by signal wire 20, and then signal isolator 10 communicates by signal wire 12 and the computing machine 13 in overhead control cabinet 14.Particularly, the signal isolator in the present embodiment 10 is arranged on signal wire, the wave filter on power and ground, decoupling device and the photoisolator etc. of metal detection subsystem 31.
In order further to prevent the phase mutual interference of the signal wire of metal detection subsystem 31 and drug/exploder detection subsystem 30, the signal wire of two subsystems should separate cabling as far as possible, spatially should separate as far as possible.When signal wire intersects, also to reduce mutually and disturb by the mode of right-angled intersection.
