Abstract
The utility model can effectively prevent law breakers from stealing user passwords by using two methods of damaging a keyboard cover and sticking a camera in the keyboard cover. The safety cover is composed of the keyboard cover (2) installed on an operation panel (4) of self-service bank equipment (1) and a control box (7) in a bank room. The keyboard cover (2) has two layers, three printed circuit boards (8) are installed between the two layers, and a plurality of small capacitors are directly arranged on the printed circuit boards and electrically connected with the control box (7) through leads (6). During work, capacity of the small capacitors on the printed circuit boards (8) is detected in turn by a central processing unit (CPU) inside the control box (7), when the law breakers stick the camera on the inner layer (5) of the keyboard cover or damage the keyboard cover (2), the capacity of the small capacitors is changed, and the CPU inside the control box (7) alarms when detecting the conditions.
Description
Technical field
The utility model relates to a kind of being used on self-help bank's equipment, prevents the code keypad safety screen that user cipher is stolen.
Background technology
Though present self-help bank's equipment is equipped with keyboard cover when dispatching from the factory, owing to do not have vandal-proof measure on the keyboard cover, be easy to destroyed and lost efficacy by the lawless person.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of cryptosecurity cover, and purpose prevents that exactly the lawless person is with destroying keyboard cover, in keyboard cover, pasting these two kinds of methods of camera and steal user cipher.
The purpose of the utility model is achieved in that the utility model is made up of the indoor control enclosure of keyboard cover and bank that is installed on self-help bank's operation of equipment panel; Keyboard cover is double-deck; Process by non-metallic materials such as plastics; Between two-layer inside and outside the keyboard cover, printed circuit board (PCB) is installed; Directly be shaped on a plurality of little electric capacity on the printed circuit board (PCB), two electrodes of each little electric capacity are electrically connected with bank indoor control enclosure through the hole that lead-in wire passes on the former self-help bank operation of equipment panel.
Control enclosure is made up of the circuit board in shell and the shell, and circuit board is welded by printed circuit board (PCB) and electronic component.
During work; Control enclosure is by mains-supplied, and CPU constantly carries out detecting in turn of capacity to the little electric capacity on the printed circuit board (PCB) in the control enclosure, and the RC circuit that forms through a fixed resistance specifically carries out discharging and recharging the time that discharges and recharges of measuring repeatedly to small capacitor; In case the lawless person has pasted camera in keyboard cover; Because the metal of conduction is arranged in the camera, will change the capacity of small capacitor, make time of capacitor charge and discharge at this place elongated; CPU in control enclosure monitors this situation, will send warning.
When the lawless person destroys keyboard cover or other lower keyboard cover and since be placed in the small capacitor in the keyboard cover number change or completely without, the CPU in the control enclosure monitors this situation, also can send warning.
The beneficial effect of the utility model is: prevented that effectively the lawless person from installing these two kinds of methods of camera with the destruction keyboard cover with in keyboard cover and stealing user cipher, thereby guaranteed the safety of fund, realized the purpose of the utility model preferably.
Description of drawings:
Describe below in conjunction with accompanying drawing:
Fig. 1 is the installation site synoptic diagram of the utility model keyboard cover.
Fig. 2 is keyboard cover transverse section and and indoor control enclosure electrical connection diagram.
Fig. 3 is the local enlarged diagram of one jiao of printed circuit board (PCB).
Among the figure: 1. self-help bank's equipment, 2. keyboard cover, 3. code keypad, 4. guidance panel, 5. keyboard cover internal layer, 6. lead-in wire, 7. control enclosure, 8. printed circuit board (PCB), the absolute electrode of 9. little electric capacity, the common electrode of 10. little electric capacity, the 10. no Copper Foil place of printing forme.
Embodiment
The utility model is divided into outdoor and indoor two parts; Outdoor section is exactly a keyboard cover 2; Indoor section is exactly a control enclosure 7; Lead-in wire 6 through printed circuit board (PCB) 8 between two parts is electrically connected, and keyboard cover 2 is pasted the correct position of guidance panel 4 middle part code keypads 3 tops that are fixed on self-help bank's equipment 1, and control enclosure 7 is placed in indoor correct position.
During work; Control enclosure 7 is by mains-supplied, and CPU constantly carry out detecting in turn of capacity to the little electric capacity on the printed circuit board (PCB) 8 in the control enclosure 7, and the RC circuit that forms through a fixed resistance specifically carries out discharging and recharging the time that discharges and recharges of measuring repeatedly to small capacitor; In case the lawless person has pasted camera at keyboard cover internal layer 5; Because the metal of conduction is arranged in the camera, will change the capacity of small capacitor, make time of capacitor charge and discharge at this place elongated; CPU in control enclosure 7 monitors this situation, will send warning.
When the lawless person destroys keyboard cover 2 or other lower keyboard cover 2 and since be placed in the small capacitor of printed circuit board (PCB)s 8 in the keyboard cover 2 number change or completely without, the CPU in the control enclosure 7 monitor this situation, also can send warning.
Through the enforcement of the utility model, prevented effectively that the burglar from destroying keyboard cover 2 and these two kinds of methods of camera are installed in keyboard cover 2 steal user cipher, thereby guaranteed the safety of depositor's fund, made contribution for building a harmonious society.
Claims (1)
1. capacitor induction type self-help bank code keypad safety screen; The indoor control enclosure (7) of keyboard cover (2) and bank by being installed on self-help bank's equipment (1) guidance panel (4) is formed; It is characterized in that; Keyboard cover (2) is double-deck, is processed by non-metallic materials such as plastics, and this is equipped with printed circuit board (PCB) (8) between two-layer at the skin of keyboard cover 2 and keyboard cover internal layer 5; Directly be shaped on the absolute electrode (9) of little electric capacity on the printed circuit board (PCB) (8), the common electrode (10) of absolute electrode of each little electric capacity (9) and little electric capacity all passes through the hole control enclosure (7) indoor with bank that lead-in wire (6) passes on the guidance panel (4) of former self-help bank equipment (1) and is electrically connected.
