Abstract
The utility model can effectively avoid lawbreakers to steal user passwords by damaging a keyboard cover and pasting a camera in the keyboard cover. An electromagnetic induction type safety cover for a self-help bank password keyboard is composed of the keyboard cover (2) installed on an operation panel (4) of self-help bank equipment (1) and a control box (7) installed in a bank room. An electromagnetic coil (5) is inlaid in the keyboard cover (2), and two end leads (6) of the electromagnetic coil (5) are electrically connected with the control box (7) installed in the bank room. When the safety cover works, circuit components in the control box (7) and the electromagnetic coil (5) in the keyboard cover (2) form an LC oscillation circuit so as to form electromagnetic oscillation with fixed frequency, once the lawbreakers paste the camera in the keyboard cover, damage or pull out the keyboard cover (2), LC oscillation parameters are changed or oscillation conditions are damaged, a central processor unit (CPU) in the control box (7) gives out an alarm when monitoring the condition.
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 processed by non-metallic materials such as plastics; Be embedded with a solenoid that adapts with the keyboard cover shape at the keyboard cover body, the two ends of this solenoid lead-in wire is electrically connected with bank indoor control enclosure through the hole 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 circuit component and the solenoid in the keyboard cover in the control enclosure constitute a LC oscillating circuit; Form the electromagnetism concussion of a fixed frequency, in case the lawless person has pasted camera in keyboard cover, because the metal of conduction is arranged in the camera; Will change the parameter of LC oscillating circuit or destroy the concussion condition; Make the frequency shift of LC oscillating circuit or stop concussion, the CPU in control enclosure monitors this situation, will send warning.
When the lawless person destroys keyboard cover or other lower keyboard cover, because the solenoid or the lead-in wire that are embedded in the keyboard cover are broken, concussion is stopped, the CPU in the control enclosure monitors this situation, also can send warning.
The beneficial effect of the utility model is: effectively prevented the lawless person with destroy keyboard cover and in keyboard cover, install camera these two kinds common method steal 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 the embedded solenoid synoptic diagram of keyboard cover.
Fig. 3 is keyboard cover transverse section and and indoor control enclosure electrical connection diagram.
Among the figure: 1. self-help bank's equipment, 2. keyboard cover, 3. code keypad, 4. guidance panel, 5. solenoid, 6. lead-in wire, 7. control enclosure.
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 10; Lead-in wire 6 through solenoid 5 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.When injection moulding keyboard cover 2; Putting into solenoid 5 in the injection mold; Just embedded solenoid 5 in the body of the keyboard cover 2 that is injection molded into, the lead-in wire 6 of this solenoid 5 is electrically connected with bank indoor control enclosure 7 through the hole on the guidance panel 4 (this hole is just in time covered by the following flange of keyboard cover 2 after pasting keyboard cover 2).
During work, control enclosure 7 is by mains-supplied, and the solenoid 5 in circuit component in the control enclosure 7 and the keyboard cover 2 constitutes a LC oscillating circuit; Form the electromagnetism concussion of a fixed frequency, in case the lawless person has pasted camera in keyboard cover, because the metal of conduction is all arranged in the camera; Will change the parameter of LC oscillating circuit or destroy the concussion condition; Make the frequency shift of LC oscillating circuit or stop concussion, the 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, broken owing to be embedded in the keyboard cover 2 interior solenoid 5 or 6 quilts that go between, concussion is stopped, 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. induction 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; Be embedded with a solenoid (5) that adapts with keyboard cover (2) shape at keyboard cover (2) body, the two ends lead-in wire (6) of this solenoid (5) is electrically connected through the hole control enclosure (7) indoor with bank on former self-help bank equipment (1) guidance panel (4).
