Specific embodiment
Technical solution of the present invention is described in further detail with reference to the accompanying drawing:
Those skilled in the art can understand that unless otherwise defined, all terms used herein (including skill
Art term and scientific term) there is meaning identical with the general understanding of those of ordinary skill in fields of the present invention.Also
It should be understood that those terms such as defined in the general dictionary should be understood that have in the context of the prior art
The consistent meaning of meaning will not be explained in an idealized or overly formal meaning and unless defined as here.
Fig. 1 is the structural diagram of the present invention.As shown in Figure 1, electromagnetic lock of the present invention includes lock 1, lock body 12
With controller 5;The lock 1 be equipped with sensing chip 2 and lockhole 6, the lock body 12 include approach switch sensor 3, lock tongue 7,
Iron-core coil 9, handle 10, the first electromagnetic coil 8, the second electromagnetic coil 11 and lock housing 4;The lock housing 4 is for coating lock body 12
The other components for including.
One end of iron-core coil 9 is located in the first electromagnetic coil 8, and the other end is located in the second electromagnetic coil 11, the first electricity
There are gaps between magnetic coil 8 and the second electromagnetic coil 11;Handle 10 be located at the first electromagnetic coil 8 and the second electromagnetic coil 11 it
Between, and it is vertical with iron-core coil 9 connected;Lock tongue 7 is fixed on iron-core coil 9 close to one end of the first electromagnetic coil 8, for by hand
The drive of handle 10 moves in lockhole 6;The sensing chip 2 is opposite with approach switch sensor 3;
Controller 5 is connected with approach switch sensor 3, the first electromagnetic coil 8, the second electromagnetic coil 11 respectively by conducting wire
It connects.As shown in Fig. 2, controller 5 includes main control chip 51, power conversion module 52, RF module 53 and drive module 54;The electricity
The output end of source conversion module 52 is connected with the first input end of main control chip 51, for powering to main control chip 51;The master
The second input terminal and approach switch sensor 3 for controlling chip 51 connect.Approach switch sensor 3 is by judging itself and sensing chip
The distance between 2 judge the switch state of door.In the present embodiment, when the distance between approach switch sensor 3 and sensing chip 2 is small
When 6 millimeters, it is believed that door is in closed state, shuts instruction from approach switch sensor 3 to the transmission of main control chip 51 at this time.Institute
The third input terminal and RF module 53 for stating main control chip 51 connect, described to open for receiving the unlocking instruction of radiofrequency signal form
Radio-frequency signal source of the lock instruction from forms such as mobile phones, also may be from the radio-frequency cards such as RFID or NFC.The drive module 54 it is defeated
Enter end to connect with the output end of main control chip 51, for receiving the unlocking of main control chip 51 and shutting instruction;The drive module
