Abstract
The utility model relates to a CPU emergence circuit, in particular to an independent CPU emergence circuit used for the intelligent lock. The utility model adopts the technical proposal that the independent CPU emergence circuit used for intelligent lock comprises an outer lock microprocessor U1 and an inner lock microprocessor U2, the matched code is arranged between the outer lock microprocessor and the inner lock microprocessor, a coupling mechanism is arranged for connecting the power supply, the inner lock microprocessor is electrically connected with the independent actuator. The utility model has the advantages that the two routes of CPU and actuators are completely independent, no electronic and coupled communication is arranged between the actuators, therefore, safety, confidentiality and reliability of the intelligent lock can be greatly improved.
Description
Technical field: the utility model relates to a kind of CPU emergency circuit, relates in particular to a kind of separate CPU emergency circuit that is used for the intelligence lock.
Background technology: modern intelligence lock comprises IC card lock, induction kayser, Fingerprint Lock etc., all is to utilize computer technology to realize intelligent managements such as time control, memory, unlatching control of authority to lockset.But, when fault occurring, must take emergency measures, so there is the people to open as emergency measure with machinery again owing to technical sophistication.Greatly reduce the safety of intelligence lock like this, in other words, its safety, confidentiality just are equal to common mechanical lock.So the someone has invented two cpu circuits again, promptly start another road cpu circuit during one road cpu circuit fault, be called as two cpu circuits.But the shared electric clutch of common two cpu circuits and a bridge-type promote circuit.When if electric clutch, bridge-type promote that circuit breaks down or the bound fraction of the two such as relay, switch etc. break down, whole lock all will become deadlock like this.As notification number is that CN2329733Y, the patent No. are that the utility model patent that ZL98215002.4 a kind of is used for the emergent lock of micro computer of IC-card door lock is exactly this structure.
Summary of the invention: technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, and the separate CPU emergency circuit that is used for the intelligence lock of a kind of safety, confidentiality, good reliability is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of separate CPU emergency circuit that is used for the intelligence lock, comprise microprocessor U2 in outer microprocessor U1 of lock and the lock, lock in outer microprocessor and the lock and be provided with the password that is complementary between the microprocessor, they are electrically connected and connect power supply by combining mechanism, microprocessor is electrically connected with executing agency independently in the described lock.
The beneficial effects of the utility model are: because two road CPU and bridge circuit are independent fully separately, do not have the contact of any electronics and interlock aspect between mutually, so just improved safety, confidentiality, the reliability of intelligent lock greatly.
Description of drawings:
Accompanying drawing 1 is a theory diagram of the present utility model;
Accompanying drawing 2 is the outer microprocessor circuit figure of lock of the present utility model;
Accompanying drawing 3 is microprocessor circuit figure in the lock of the present utility model.
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is further described: as shown in the figure, a kind of separate CPU emergency circuit that is used for the intelligence lock, comprise microprocessor 2 in outer microprocessor 1 of lock and the lock, lock in outer microprocessor 1 and the lock and be provided with the password that is complementary between the microprocessor 2, they are electrically connected and connect power supply 4 by combining mechanism 3, and microprocessor 2 is electrically connected with executing agency 5 independently in the described lock.The vdd terminal of the outer microprocessor 1 of described lock is connected with the positive pole of power supply 4 with the GP3 end, and GP2 end and GP4 end are by resistance R 1 ground connection, and VDD, GP0, GP1, GND end are connected respectively to stick part J13-1; The VDD of microprocessor 2 in the described lock, GP0, GP, the GND end is connected respectively to stick part J2 3-2, stick part J1 3-1 and stick part J2 3-2 constitute described combining mechanism 3, the GP3 of microprocessor 2 end is connected with the positive pole of power supply 4 by stick part J2 3-2 in the lock, and be connected with the emitter stage of triode Q5-1 in the executing agency 5, the GP2 end is connected by the base stage of resistance R 4 with triode Q5-1, described executing agency 5 also comprises inductance L 5-3, diode D5-4, with electric clutch 5-5, the end of described inductance L 5-3 and diode D5-4 is also received on the base stage of triode Q5-1, the other end is connected with electric clutch 5-5 output, and the base stage of triode Q5-1 is connected with the input of electric clutch 5-5.Inductance L 5-3 also can be a relay.Also be serially connected with light emitting diode between the GP2 of the outer microprocessor 1 of described lock and GP4 end and the resistance R 1, can reflect whether power supply 4 is connected.GP3 also is connected with stick part JP with vdd terminal.When power supply 4 damages, can external other power supplys.Its operating principle is: all cut off the power supply when the outer microprocessor of microprocessor 1 and lock 2 is flat in the lock, power supply 4 is connected when both dock by stick part J1 (3-1) and stick part J2 (3-2), external microprocessor 1 at first produces some byte random numbers and sends to internal microprocessor 2, internal microprocessor 2 receives the random number that 3 back loopback some bytes oneself generate, and issues external microprocessor 1.Then, external microprocessor 1 carries out computing (promptly encrypting) with password and two batches of random numbers by certain algorithm, and sends to internal microprocessor 2.After internal microprocessor 2 receives second batch data that external microprocessor 1 sends, itself and two batches of random numbers are carried out computing (i.e. deciphering) by certain algorithm, compare with its password, the identical electric clutch 5-5 that promptly connects unblanks.Otherwise, then do not unblank.
