The selection of the delay time T needs to comprehensively consider the actual number of the password identification holes, the distance between the adjacent password identification holes and the actual resistance factor of the key inserted into the key slot, and the main logic is as follows: in the process that the key enters the key slot, in the process that the axis of one magnetic conductive sheet and the axis of one password identification hole are completely overlapped from beginning to approach, the coverage area of the magnetic conductive sheet between the first transition hole and the second transition hole is gradually increased, when the coverage area reaches a certain value, the voltage signal generated by the piezoelectric ceramic stack of the path possibly happens to reach the threshold voltage of the path, actually, the magnetic conductive sheet does not correspond to the magnetic conductive sheet finally, and when the axis of the magnetic conductive sheet is overlapped with the password identification hole, the final voltage signal generated by the piezoelectric ceramic stack of the path exceeds the fluctuation range +/-V of the threshold voltage of the path’Therefore, when the single chip input interface corresponding to any one of the password identification holes receives a voltage signal belonging to a threshold voltage, whether the voltage signal of the path is out of tolerance within a period of time needs to be determined through a delay instruction, so that whether the voltage signal is an effective threshold voltage signal is determined, obviously, the setting of the delay time T is related to the above factors, and the adjustment needs to be carried out in the actual engineering.

Electromagnetic switch actuating machineThe specific working process of the structure and the relay is the same as that of the electronic coded lock in the prior art, and the detailed description is omitted here.
The control system of the magnetic-electric coupling lock cylinder utilizes the magnetostrictive effect of the giant magnetostrictive rod, and the magnetic conductive sheets with different thicknesses are connected between the corresponding first transition hole and the second transition hole by inserting the key, so that the magnetic flux from the permanent magnet received by the giant magnetostrictive rod is changed, the internal stress of the giant magnetostrictive rod is further changed, the compression amount of the corresponding piezoelectric ceramic stack is changed, a certain voltage signal is generated by the piezoelectric effect, the thickness of the magnetic conductive sheet on the key can be judged by judging the voltage signal, and the process of password identification is completed; the control method of the magnetic-electric coupling lock cylinder ingeniously utilizes the magnetostrictive effect and the piezoelectric effect, compared with an electronic coded lock in the prior art, the code of the control method is recorded through a key entity, so that random cracking through a simple number-collecting mode is difficult to carry out, compared with a mechanical coded lock in the prior art, the control method of the magnetic-electric coupling lock cylinder overcomes the problem that a key in the prior art is easy to copy due to the fact that the control method is completely different from a traditional key, and in combination, the control method of the magnetic-electric coupling lock cylinder is high in safety.
