Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described; The present embodiment is descriptive, is not determinate, can not limit protection range of the present utility model thus.
A kind of electromagnetic shielding box for special transformer terminals wireless public network communication automation system test, the rectangular box structure be made up of shield door 1, side plate 3, top board 2, access panel 4 and base plate (not having label), wherein shielding door-plate is inlaid between two side plate front portions, by driving stepper motor, access panel is encapsulated in two side plate rear portions; On base plate in casing by track 11 run have structure for conveying 9, lifting device 10 is installed on the conveyor, lifting device is provided with unit 7 of plugging into, correspondence plug into unit top board in be fixed with RFCD radio-frequency (RF) coupler 6.
The inboard of described shield door is fixed with plane wave absorbing thin film plate 5, and this wave absorbing thin film plate can suppress the surface electromagnetic waves such as row ripple, Creeping Wave and guided wave effectively; All be fixed with flat taper in top board, sidewall and access panel inboard and inhale ripple plate 8, wave head inhaled by the ripple plate effective electromagnetic wave absorption in tip by its uniform needle-like of making is inhaled in this flat taper.
In the present embodiment accompanying drawing, the driver parts such as described stepping motor, air motor and type of drive are prior aries, so there is no provide its concrete structure.
Operation principle of the present utility model is:
In special transformer terminals wireless public network communication automation system test process, when acquisition terminal module arrives the station of wireless public network communication test, after streamline PLC sends warehouse entry request, testing equipment is under the control action of its PLC, progressively complete that motor enters, line stretcher enters, fixed station liter, shield door close, terminal enters action, successfully enter electromagnetic shielding box to realize acquisition terminal, then realized the measurement of special transformer terminals wireless public network communication performance parameter by software control.After measurement completes, software sends test settling signal to testing equipment PLC, send to streamline PLC delivering from godown request by testing equipment PLC again, simultaneously testing equipment PLC completes with this that terminal moves back, shield door is opened, line stretcher moves back, motor moves back and operates to realize the object that acquisition terminal goes out electromagnetic shielding box.
