In the actual use state of the door control device, as shown in fig. 4, 5 and 6, the hanger rail 10 is connected with the door body 50 and is installed at the door opening of the barrier-free toilet, one electromagnet group 22 of the driving unit 20 is located above the door opening, the electromagnet group 22 and the magnetic attraction piece 42 of the sliding piece 40 have opposite magnetic poles to generate an attraction effect, the other electromagnet group 22 of the driving unit 20 is far away from the door opening and generates a repulsive effect with the magnetic poles of the magnetic attraction piece 42 of the sliding piece 40, so that the door body 50 is normally closed, meanwhile, the electric mortise lock 30 pushes the magnetic piece 342 of the bolt 34 through the magnetic field repulsion of the electromagnet 32, so that the bolt 34 is sunk through the slot 13 and is inserted into the locking hole 412 of the sliding seat 41, the door body 50 forms a locking state, the outer inductor 61 is installed outside the barrier-free toilet, the inner inductor 62 is installed inside the barrier-free toilet, the outer inductor 61 and the outer inductor 62 is electrically connected with the electric control plate 21 of the driving unit 20, and then the electric control plate 21 receives electromagnetic signals of the outer inductor 61 and the electric inductor 62 to generate further electromagnetic signals of the electromagnetic coil pair of the electromagnet groups 22 and the electromagnet coil pair 221 to generate a change of magnetic field signals of the electromagnet 32; therefore, when the user wants to open the door 50 to enter the barrier-free toilet, as shown in fig. 7, 8 and 9, the user simultaneously applies a gesture to the door sensor 61 to generate a door opening sensing signal to the electric control board 21, the electric control board 21 receives the signal to control the electromagnet 32 to generate a magnetic field change and the electromagnetic coil 221 to generate a magnetic pole change, at this moment, the electromagnet 32 of the electric mortise lock 30 attracts and pulls the magnetic member 342 due to the magnetic field change, so that the latch 34 rises to be separated from the locking hole 412 of the sliding seat 41 to form an unlocking state of the door 50, the electromagnet group 22 above the door opening has the same magnetic pole state as the magnetic member 42 of the sliding member 40 after the magnetic pole change of the electromagnetic coil 221, so that the electromagnet group 22 and the magnetic member 42 generate a repulsive effect, and the electromagnet group 22 far away from the electromagnetic coil 221 has a different magnetic pole state as the magnetic member 42 of the sliding member 40 after the magnetic pole change, thereby generating an attractive effect, and the electromagnet member 42 of the sliding member 40 is attracted by the magnetic pole change, so that the electromagnet member 42 is attracted by the magnetic pole change and the magnetic pole change, the electromagnetic member 42 is further moved along the door opening the sliding slot 50.

When a user enters the barrier-free toilet, as shown in fig. 10, 11 and 12, he needs to get his hand close to the inner sensor 62 and perform gesture sensing to make the inner sensor 62 generate a door closing sensing signal and transmit the door closing sensing signal to the electric control board 21, and control the two electromagnet sets 22 to generate magnetic pole change again through the electric control board 21, at this time, the electromagnet set 22 far from the doorway has the same magnetic pole state as the magnetic attraction piece 42 of the sliding piece 40 after the magnetic pole change of the electromagnetic coil 221, so as to generate a repulsive effect, and the electromagnet set 22 located above the doorway has a different magnetic pole state as the magnetic attraction piece 42 of the sliding piece 40 after the magnetic pole change of the electromagnetic coil 221, so that the electromagnet set 22 and the magnetic attraction piece 42 generate an attractive effect, and thus the sliding piece 40 is driven to move along the doorway 12 to the direction, and further drive the door body 50 to close the door body 50, when the door body 50 is in the closed state, the electric control board 21 also recognizes that the door body 50 is closed through the changing state of the electromagnet set 22, so as to control the electromagnet 32 of the electric plug lock 30 to push the electromagnet set to generate a repulsive magnetic pole state to generate a different magnetic pole state as to the magnetic pole state as to make the magnetic pole of the sliding piece 34 of the sliding plug piece 34 move down the magnetic plug seat 34 through the magnetic pole seat 34, so as to form a locking magnetic pole state of the magnetic plug seat 34, and a locking piece 34 is formed by the magnetic pole 34.

In addition, when the user enters the barrier-free toilet and closes the door by sensing through the inner sensor 62, the outer sensor 61 lights up to display a light signal 611 as shown in fig. 13, so as to inform that the barrier-free toilet is in use, and the outer sensor 61 is in an un-sensing state at the same time, so as to prevent the outer sensor 61 from being sensed to open the door 50, thereby ensuring the safety of toilet use; when the door is opened by the induction of the inner inductor 62 after the toilet, the display lamp 611 of the outer inductor 61 is turned off and the state of the door body is restored, so that the door body 50 can be closed by the outer inductor 61 after the toilet is used; if the door 50 is not closed again by the external sensor 61 after the toilet, after a period of time when no human sense is taken in, the electric control board 21 of the driving unit 20 automatically controls the two electromagnet sets 22 to generate magnetic pole change, so that the door 50 can be automatically restored to the normally closed state, and simultaneously controls the electromagnet 32 to generate magnetic field change, so that the plug pin 34 of the electric mortise lock 30 is sunk and inserted into the locking hole 412 of the sliding seat 41.

Moreover, when the access control device is used for the first time, the sliding member 40 is first moved back and forth in the lower chute 12 once, the stop seats 14 at two ends of the lower chute 12 are used for stopping and limiting, and meanwhile, the linear hall sensor 23 of the driving unit 20 is used for sensing the sliding path of the sliding member 40, so as to obtain a better magnetic pole change frequency, thereby being beneficial to adjusting the displacement speed of the sliding member 40, and when the access control device is used again, the two electromagnet groups 22 can provide a better magnetic pole change time along with the sliding path of the lower chute 12, so that when the sliding member 40 is displaced to two ends, the number of the electromagnetic coils 221 with different magnetic poles can be increased through the magnetic pole change of the electromagnetic coils 221, and meanwhile, the number of the electromagnetic coils 221 with the same magnetic poles is reduced, so that the buffer speed change effect is achieved, the sliding member 40 is prevented from directly striking the two stop seats 14, and the noise is beneficial to be reduced.

In addition, when the electric mortise lock 30 is in the locked state, the elastic member 341 is pressed down by the magnetic member 342 of the plug 34 to form a compressed state, and when the power supply of the door access device is abnormal, the electric mortise lock 30 can push the plug 34 upward through the elastic member 341, so that the plug 34 is separated from the locking hole 412 of the sliding seat 41, and the door body 50 is in the unlocked state and can be pushed to be opened.

In another embodiment of the structure, the door 50 is further set to be normally opened by the outer and inner sensors 61 and 62, and the outer sensor 61 does not have the effect of normal gesture sensing opening, when a user enters the barrier-free toilet, the inner sensor 62 generates a door closing sensing signal and transmits the door closing sensing signal to the electric control board 21 by approaching the hand to the inner sensor 62 and gesture sensing, further drives the door 50 to close the door opening, and sinks the bolt 34 through the slot 13 to insert the locking hole 412 of the sliding seat 41, so that the door 50 is in a locked state, and the outer sensor 61 is turned on to display the lamp number 611, so that the lamp number 611 is turned off when the user senses the door opening through the inner sensor 62 after the user enters the toilet, and the normally opened state of the door 50 is restored. In addition, when the door 50 is in a normally open state, the external sensor 61 may additionally set a special gesture or other sensing method for emergency opening, if an emergency occurs, such as when the door 50 is not opened for a long time and the user is suspected to be faint or the internal help is required, the external sensor 61 may open the door 50 through the special gesture or other sensing method, and then rescue the user immediately to avoid the occurrence of an accident.

By the structure of the above specific embodiment, the following benefits can be obtained: the gate inhibition device of the utility model controls the electromagnet group 22 to generate magnetic pole change through the electric control plate 21 of the driving unit 20, and utilizes the principle characteristics of like poles repel and opposite poles attract to make the magnetic attraction piece 42 of the sliding piece 40 capable of being repelled and floated by the same magnetic poles of the electromagnet group 22 and the magnetic poles different to pull and displace, so as to achieve the aim of sliding and opening and closing the gate body 50, and simultaneously, the gate body 50 is electrically connected with the electric control plate 21 through the outer inductor 61 and the inner inductor 62 of the gesture sensing device 60, and the gesture sensing is utilized to trigger the driving signal, thereby achieving the effect of non-contact opening and closing the gate body 50, avoiding the mutual infection of bacteria and viruses caused by repeated contact, greatly reducing the risk of epidemic infection and facilitating the improvement of practicality.
