Property labour under the premise of, the embodiment of all other equivalent or apparent modification obtained is all fallen in protection scope of the present invention.
The embodiment of the present invention can be embodied according to the multitude of different ways being defined and covered by claim.
It should be noted that in the following description, understand for convenience, give many details.It is but very bright
Aobvious, realization of the invention can be without these details.
It should be noted that in the case where not limiting clearly or not conflicting, each embodiment in the present invention and its
In technical characteristic can be combined with each other and form technical solution.
In the course of work of lock control circuit, it may appear that unpredictable situation causes lock driving circuit persistently to export height
Level.It in this way can electron lock sustainable supply electric current.When supply electric current duration be more than certain time (such as：5 seconds) when,
Electronic lock may be burnt.
For this purpose, the embodiment of the present invention provides a kind of lock control circuit 10 for electronic lock.As shown in Figure 1, the circuit includes：
CPU12, at least one lock driving circuit 16, power supply 14 and time clamp down on circuit 18.Wherein, CPU12 controls signal for exporting,
