Accompanying drawing explanation

Fig. 1 is the non-hole intelligent lock schematic diagram based on principal and subordinate's Redundant Control of the present utility model.

Detailed description of the invention

As shown in Figure 1, non-hole intelligent lock based on principal and subordinate's Redundant Control of the present utility model, it comprises: host scm, main module of unblanking, from single-chip microcomputer, from module of unblanking, memory module, acousto-optic indicating module, power module, radio frequency card seeking module and redundant control module;

Annexation is:

Memory module, acousto-optic indicating module, power module, radio frequency card seeking module, redundant control module are all connected with host scm with from single-chip microcomputer respectively; Host scm and main model calling of unblanking, from single-chip microcomputer with from model calling of unblanking.

Power module, for for host scm, main module of unblanking, from single-chip microcomputer, from module of unblanking, memory module, acousto-optic indicating module and radio frequency card seeking module for power supply;

Memory module, prestores unlocking authority information;

Alarm module, at host scm or continuous activation unsuccessfully for three times sends alarm signal from single-chip microcomputer.

Radio frequency card seeking module, carries out card seeking action by Single-chip Controlling, reads user's key card information;

Acousto-optic hint module, for when execution of swiping the card with the card of mistake is unblanked, sends acoustic and light information;

Redundant control module, be by one independently single-chip microcomputer carry out logic control, give host scm respectively and the logical signal of alternation be provided from single-chip microcomputer, counting in the fault recurred system simultaneously, after full 3 times, controlling alarm module and report to the police.

Host scm or from single-chip microcomputer, control radio frequency card seeking module in active state and carry out card seeking action reading user key card information, transfer the unlocking authority information that memory module stores, and user's key card information and unlocking authority information are carried out contrast verification, if be verified, host scm sending controling instruction then under state of activation is to main module of unblanking, or giving from module of unblanking from single-chip microcomputer sending controling instruction under state of activation, if authentication failed otherwise attonity;

Module of unblanking can drive mechanical pin in lock freely to retreat, and then mechanical structure portion can be connected into an entirety by pin, open door by door handle driving mechanical structure.Wherein: main module of unblanking, unlocking action is performed for the control instruction according to host scm; From module of unblanking, for performing unlocking action according to the control instruction from single-chip microcomputer.

Action is:

Host scm and from single-chip microcomputer two single-chip microcomputer alternations, one when being state of activation, another is resting state.When swipe the card action time, be in the single-chip microcomputer of resting state when redundant control module activates last unblanking.Realize if last unlocking action is host scm, then redundant control module of this time unblanking activates from single-chip microcomputer, and host scm is resting state; If last unlocking action is from chip microcontroller, then redundant control module of this time unblanking activates host scm, is resting state from single-chip microcomputer;

The Single-chip Controlling radio frequency card seeking module activated is carried out card seeking action and is read user's key card information, and transfer the unlocking authority information of memory module storage, then this unlocking authority information and user's key card information are verified, if be proved to be successful, the host scm that then activates controls main module of unblanking and performs unlocking action, or activate perform unlocking action from Single-chip Controlling from module of unblanking; If authentication failed, then the host scm activated or activation send acoustic and light information from Single-chip Controlling acousto-optic hint module.

If redundant control module activates the failure of current monolithic machine, then activate another single-chip microcomputer and continue to perform unlocking action and the failed number of times of current monolithic machine activation is counted.If redundant control module is continuous activate a single-chip microcomputer failure for three times, then redundant control module trigger alarm module sends alarm signal.

Certainly; the utility model also can have other various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the utility model.
