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