Detailed description of the invention
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
Embodiment mono-: as shown in Figure 4, it comprises the part such as Wireless code sheet 21, lockset control circuit 22 to the intelligentized lockset 2 using in power system at present, is provided with the locked groove that can insert for associated key on this lockset 2.Wherein, in Wireless code sheet 21, with code value, just can identify this lockset 2 by identifying this code value, thereby prevent it to carry out maloperation.
A kind of and above-mentioned lockset 2 is used in combination error-unlocking prevention key 1, and if accompanying drawing 1 is to as shown in accompanying drawing 3, it comprises housing 11, unlocking head 12, key control circuit 13, battery 14, solenoid 15, microswitch 16 and the button 17 of powering for key control circuit 13.
Housing 11 is cuboid, and it comprises top, bottom and four sidepieces.Unlocking head 12 be arranged at housing 11 tops outside, within key control circuit 13, battery 14, solenoid 15 and microswitch 16 are arranged at housing 11.
Unlocking head 12 comprises and reads the reading terminal 121 of the code value in lockset 2, positive pole axis 122 and negative pole axle 123, and positive pole axis 122 and negative pole axle 123 lay respectively at the both sides of reading terminal 121.
Battery 14 is connected to form with positive pole axis 122, negative pole axle 123 supply access that can power for lockset control circuit 22, and microswitch 16 is arranged on supply access.Concrete, the positive pole of battery 14 is connected with positive pole axis 122 through microswitch 16, and the negative pole of battery 14 is connected with negative pole axle 123.
Button 17 is cylindrical, its sidepiece through housing 11 and extending to outside housing 11 within by housing 11 on axially at it, and this button 17 can axially be pressed and triggers the microswitch 16 that is relatively arranged on its axially upper one end place along it.On button 17, be provided with spacing hole 171, these spacing hole 171 edges are opened in the periphery of button 17 perpendicular to the axial direction of button 17, and are blind hole.Solenoid 15 is monostable solenoid, the iron core 152 that can move in the time that coil 151 is switched on that it comprises a coil 151 and is arranged at coil 151 centers, and insert in the spacing hole 171 on button 17 at least one end of this iron core 152.
Key control circuit 13 comprises MCU and various electronic component, and the output of reading terminal 121 is connected with the input of key control circuit 13, and the output of key control circuit 13 is connected with solenoid 15.
The working method of this error-unlocking prevention key 1 is:
If accompanying drawing 2 is to as shown in accompanying drawing 4, the unlocking head of this error-unlocking prevention key 1 12 is inserted in the locked groove on lockset 2, reading terminal 121 is relative with the lockset control circuit 22 in lockset 2, and positive pole axis 122 and negative pole axle 123 connect with two lead-out wires of lockset control circuit 22 respectively.First reading terminal 121 reads the code value in the Wireless code sheet 21 of lockset 2, and sends it in key control circuit 13 and identify, and this identification realizes by MCU, and after identification is passed through, key control circuit 13 outputs signal to solenoid 15 and switches on.The solenoid 15 of energising shrinks, and its iron core 152 is by throwing off in the spacing hole 171 of button 17 sides.Now can press button 17 downwards, press button 17 to the direction of microswitch 16, so that button 17 can touch microswitch 16, thereby positive pole axis 122 is connected with the positive pole of battery 14.Charged positive pole axis 122 and negative pole axle 123 connect into loop with the lockset control circuit 22 in lockset 2, use to lockset control circuit 22 to power.
And after the operation of lockset 2 completes, by extracting in the locked groove on lockset 2, reading terminal 121 reads less than the code value in lockset 2 by this error-unlocking prevention key 1, make key control circuit 13 None-identified code values and cut off solenoid 15 is powered.After power-off, the iron core 152 of solenoid 15 again ejects and inserts in the spacing hole 171 of button 17 sides, thereby resistance button 17 is again depressed, and then cannot touch microswitch 16, and can disconnect being connected of positive pole axis 122 and battery 14, also just disconnect the supply access of lockset control circuit 22.
