See also Fig. 6, described control circuit comprises terminal board J1, travel switch, voltage transformation module U1.In the present embodiment, arrange four take travel switch and be explained as preferred version, but be not limited to this, in actual use, the trip switch can arrange several.
Described terminal board J1 is 10 pin terminal boards, and its 1 pin and 2 pin be used for to receive the voltage signal of unblanking of main control system output, its respectively with input Vin1 pin and the Vin2 pin of this voltage transformation module U1.Described travel switch K1, K2 export normally closed signal, and it is exported by 3 pin, 4 pin, 5 pin, 6 pin of this terminal board J1 respectively.Signal is often opened in described travel switch K3, K4 output, and it is exported by 7 pin, 8 pin, 9 pin, 10 pin of this terminal board J1 respectively.The output of described voltage transformation module U1+Vo pin is connected with the two ends of this electromagnet respectively with the GND pin.
The trip K switch 1, K2, K3, K4 are subjected to locking bar 108 controls of this lockset.When locking bar 108 inserted latch arm hole 107, travel switch K1, K2 were normally closed, and travel switch K3, K4 often leave; After locking bar was opened disengaging latch arm hole 107, travel switch K1, K2 became disconnection, and travel switch K3, K4 connect.
More excellent, be provided with pressure cell R5 between the input Vin1 pin of described voltage transformation module U1, the Vin2 pin, for the protection of this control circuit (for example, preventing that this control circuit is struck by lightning).
More excellent, when carrying out signal of telecommunication release, being the convenient lockset state that shows, the described electric unit that unblocks also is provided with a release indicating device.See also Fig. 5 and Fig. 7, described release indicating device is for being provided with a circuit board 115.This circuit board 115 is provided with led state lamp, resistance R 1 and is used for the capacitor C 1 of filtering; This led state lamp and the two ends that are connected to electromagnet 114 after this resistance R 1 is connected, this capacitor C 1 is in parallel with this led state lamp.
More excellent, body is provided with light-guiding pillar 116, and being used for derives the light that the led state lamp sends outside housing.
More excellent, operator is upspring automatically for making unlock button 111 behind capable of being unlocked by pressing button 111, is provided with return spring 117 in this unlock button 111.
Please continue to consult Fig. 1 to Fig. 5, the described machinery unit that unblocks comprises and being located in this shell, be used for the RFID module (not shown) of identification intelligent computer key and be located at lock knob 118 in the unlock hole 106 of this body 102, an end of this lock knob 118 is connected with described securing rod 109.
More excellent, the state for ease of the monitoring lockset also is provided with a locking bar state detection unit in this electrical anti-error lock.This locking bar state detection unit comprises push shaft 119 and the touch-switch 120 that links with this push shaft 119; This push shaft 119 is located in the latch arm hole 107 of this body 102, and when described locking bar 108 inserted this latch arm hole 107, this push shaft 119 contacted with this locking bar 108.
More excellent, separate with locking object 121 for preventing this locking bar 108, the phenomenon of empty locking occurs, this locking bar 108 is connected in locking object 121, and for example, movable snaps fit onto on the locking object 121.
During this electrical anti-error lock operation, have signal of telecommunication release, mechanical release, three kinds of mode of operations of emergency mechanical release.
When signal of telecommunication mode of operation, main control system output one voltage signal of unblanking, after terminal board in the signal of telecommunication control circuit of the electric unit that unblocks receives the voltage signal of unblanking, be converted to low-voltage dc voltage and export electromagnet 114 to through the voltage transformation module U1 voltage signal of will unblanking, electromagnet 114 produces magnetic force, with lock pin 113 sucking-off from the draw-in groove of operator link 112, make operator link 112 be in movable state; Simultaneously, terminal board meeting driving LED circuit board 115 makes the led state lamp on the led circuit plate 115 light by pre-defined rule, and the light of generation conducts to outside the shell by light-guiding pillar 116, the prompting operator; At this moment, operator is pressed unlock button 111 moves operator link 112, and operator link 112 moves the generation lateral thrust, forces the end of securing rod 109 to withdraw from draw-in groove on the locking bar 108; At this moment, locking bar 108 just can withdraw from latch arm hole 107 under the effect of external force, and after locking bar 108 withdrawed from, push shaft 119 lost with locking bar 108 and contacts, and produces displacement and decontrols touch-switch 120, and touch-switch 120 produces a switching signal and feeds back to main control system.During locking, operator directly is inserted into locking bar 108 in the latch arm hole 107, and securing rod 109 is again locked with locking bar 108, and locking bar 108 links together with locking object 121, and therefore the phenomenon of empty locking can not occur.Contact with push shaft 119 in locking bar 108 insertion process, push shaft 119 touches touch-switch 120, and touch-switch 120 produces a switching signal and feeds back to main control system.
During mechanical release, operator directly is inserted into Computerized intelligent key (not shown) in the unlock hole 106; Operation order and RFID module such as the Computerized intelligent key are complementary, and then the Computerized intelligent key will rotate, and drive simultaneously lock knob 118 and rotate, and lock knob 118 produces lateral thrust when rotating, and force the end of securing rod 109 to withdraw from draw-in groove on the locking bar 108; At this moment, locking bar 108 just can withdraw from latch arm hole 107 under the effect of external force.
As emergency appears, operator can use the mechanical type key directly to rotate lock knob 118, carries out the operation of emergency release, prevents that contingency from occuring.
The above is preferred embodiment of the present invention only, is not to limit practical range of the present invention; Every equivalence of doing according to the present invention changes and revises, and is all covered by the scope of claims of the present invention.
