Description of the drawings
Fig. 1 is block diagram of the present utility model.
Fig. 2 is control circuit theory diagram of the present utility model.
Fig. 3 is band electric alarm circuit schematic diagram.
Specific embodiment
As seen from Figure 1, the utility model includes mechanical lock, the key of mechanical lock, the intelligent machine of storage mechanical lock key
Lock key storage appts, control circuit.Its operation principle is by carrying additionally Key machine in band electric cabinet door, switch operation handle etc.
Tool is locked, and mechanical lock key is stored in intelligent machine lock key storage appts after lock, and intelligent machine lock key storage appts are
A kind of special key storage device, by control circuit the opening and closing of intelligent machine lock key storage appts is controlled.Control circuit
With powered arbitration functions, if powered, storage appts cannot be opened, and operating personnel cannot just take out mechanical lock key, powered
Cabinet door, disconnecting link just serve the effect of forced blocking, and after only equipment is normally stopped transport without electricity, corresponding storage appts just can be opened,
Now key could take out the corresponding cabinet door of unlatching or operation disconnecting link, due to by " one lock of a key " configuration, the key of taking-up
Spoon must not open adjacent other cabinet door, and due to mechanical lock locking intuitively firmly, personnel are difficult destruction, therefore the party with brute-force
Case reliability is high；The key storage device adopts various sensitive electric currents, electric field simulation induction of signal circuit enhanced processing, can
With whether powered in wire netting door or observation window external detection cabinet interior element, it is also possible to from the sensor two of existing electrification display
Analog signalses are obtained on secondary little line or the little line of voltage transformer secondary, sensitivity is high, therefore the storage appts can be easily
Near switch cubicle low-pressure chamber or rear cabinet door external observation window, while reliable anti mis-closedown function is played, dexterously
Avoid newly-increased secondary circuit, the inconvenience of the punching installation that has a power failure.
As it is clear from fig. 2 that control circuit of the present utility model includes display, single-chip microcomputer SN8P2501A, power supply, keyboard, close
Code memory unit, current detecting unit, electric field detector unit, band electric alarm circuit, unlocking circuit, reset circuit.Keyboard is to use
Carry out input numerical ciphers and perform various functions, single-chip microcomputer is connected by input through keyboard password by user, used by single-chip microcomputer
The password that family is input into password and preserves with you is compared, and when password is correct, now system starts sensed current signal and electricity
Field information, when finding to there is electric current or electric field, then illustrates that detected high-tension switch cabinet is powered, system mask solenoid,
Close unlocking function, and alert.Conversely, explanation high-tension switch cabinet is in power down mode, now system control electromagnetism
Coil is turned on, and starts unblock.When password bad, now system alert.
According to actual conditions keyboard input part component selections 4*4 matrix keyboard, password storage part is come from AT24C02 chips
Complete.
The utility model adds an electricity for the reliability spy for increasing latch portion on the basis of electroscope circuit
Sub- cipher control part so that when electric field and current detecting unit measure powered interval without electricity, and electronic cipher part is input into just
Really, then mechanical lock is unlocked, and the mechanical lock locking if not meeting of any condition must not be unlocked.Additionally, when forgetting Password, system can
Mechanically open.
It can be seen from figure 3 that band electric alarm circuit of the present utility model includes PNP type triode Q1, the first NAND gate integrated package
4011A, the second NAND gate integrated package 4011B, self-test switch S1；The emitter stage of triode Q1 is electric with a termination of second resistance R2
Source, the base stage that the other end of second resistance R2 terminates triode Q1 with the one of first resistor R1, the other end of first resistor R1
Input is connect, input is connected to electric field detection amplifying circuit end, and the colelctor electrode of triode Q1 connects 3rd resistor R3 and the 4th resistance
One end of R4, the other end ground connection of 3rd resistor R3, the resistance R5's of another termination the 5th and the first electric capacity C1 of the 4th resistance R4
One end, the first electric capacity C1 the other end ground connection, another termination the first NAND gate integrated package 4011A of the 5th resistance R5 two and connect
Input, the output second NAND gate integrated package of termination of the first NAND gate integrated package 4011A 4011B's and connects input, the
The output end of the output terminal strip electric alarm circuit of two NAND gate integrated package 4011B, between output end and ground and to be connected to the 6th electric
Resistance R6 and the second electric capacity C2；Self-test switch S1 is connected between input and ground.
For live detection module, when module surrounding electric field very weak (being substantially at zero potential), input is connected to
The electric field at end detects the ac voltage signal no signal that amplifying circuit is obtained, and now triode Q1 is not turned on, the collection of triode Q1
Electrode voltage is zero, and the output end level after two-stage NAND gate 4011A and 4011B is low level.Now do not report to the police, thus
It can be seen that, when module is in zero electric field, do not send corresponding warning message.When the change of module surrounding electric field signal is big, input electricity
The AC signal that field detection amplifying circuit is obtained also becomes big, and now input signal is exchanged with frequency with circuit.Due to the signal being input into
For AC signal, when voltage signal is in positive half cycle, make defeated by the triode Q1 base stages obtained by resistance R1 and R2 partial pressure
Enter voltage signal to raise, and uprise as the change of input end signal is big, so as to prevent the conducting of triode Q1, now output end
Level still be low level；When input voltage signal is in negative half period, make by three poles obtained by resistance R1 and R2 partial pressure
Pipe Q1 base stage input voltage signals diminish, and with the change step-down greatly of input end signal, so as to promote the conducting of triode Q1,
Now the colelctor electrode level signal of triode Q1 is high level, by the low-pass filter circuit of resistance R4 and electric capacity C1 compositions to height
Frequency signal is filtered, and increases the antijamming capability of system external circle high-frequency signal, through two-stage NAND gate 4011A and 4011B
The level of output is reported to the police for high level.As can be seen here, when module is in strong AC field, corresponding alarm signal is sent
Breath.Intelligent machine lock key storage appts are closed during warning, and key be cannot take out.
Additionally, band electric alarm circuit of the present utility model also has self-checking function, it is controlled using self-test switch S1, when
When self-test switch S1 is closed, triode Q1 is now driven, turn on triode Q1, now the colelctor electrode level signal of triode Q1
It is high level through the level of two-stage NAND gate output for high level, is achieved in the self-inspection to warning circuit.
