Synchronous opening and closing of double doors using a magnetic electronic access control and its control method

Abstract

The present invention discloses a synchronous opening and closing method for double doors implemented by a magnetic electronic access control and its control method. The synchronous opening and closing of the double doors includes a regulated DC power supply, a left door node, a right door node, a relay, and a magnetic lock connected in series in sequence. The regulated DC power supply provides a working power supply with a stable DC voltage for the magnetic lock. Both the left door node and the right door node are closed when the door is closed and opened when the door is opened. The external opening instruction controls the opening and closing of the normally closed node of the relay. The synchronous opening and closing of the double doors implemented by the magnetic electronic access control in the present invention is easy to implement and has a low cost, and can be used for the control of the synchronous opening and closing of any double doors, such as an intelligent container with double doors.

Description

Technical Field

[0001] The present invention relates to the technical field of magnetic electronic access control, and particularly relates to a synchronous opening and closing method for double doors realized by a magnetic electronic access control and its control method. Background Art

[0002] The application of magnetic electronic access control is becoming more and more extensive, but it is generally used for the access control of single doors. When the width of a single door is relatively wide, it is inconvenient for users to open and close the door, and it will occupy a large space. It is necessary to change the single door to a double door. Since the magnetic lock allows the door to be opened by short-term power-off and demagnetization, and then re-powered to generate magnetic force to close the door again, if the demagnetization and magnetization of the magnetic lock are not controlled, when any one of the double doors is opened and then closed again, it will be sucked and locked, and the synchronous opening and closing of the double doors cannot be achieved. Summary of the Invention

[0003] In view of this, in order to solve the above problems in the prior art, the present invention proposes a synchronous opening and closing method for double doors realized by a magnetic electronic access control and its control method.

[0004] The present invention solves the above problems through the following technical means:

[0005] On the one hand, the present invention provides a synchronous opening and closing method for double doors realized by a magnetic electronic access control, including a regulated DC power supply, a left door node, a right door node, a relay, and a magnetic lock connected in series in sequence;

[0006] The regulated DC power supply provides a working power supply with stable DC voltage for the magnetic lock. Both the left door node and the right door node are closed when the door is closed and open when the door is opened. The external opening instruction controls the opening and closing of the normally closed node of the relay.

[0007] On the other hand, the present invention also provides a control method for a synchronous opening and closing method for double doors realized by a magnetic electronic access control; the method includes the following steps:

[0008] S1. When any one of the left and right doors is opened, the circuit is disconnected, the magnetic lock is demagnetized, and both the left and right doors are in the open state;

[0009] S2. When both the left and right doors are closed, if no external opening instruction is received, the circuit is closed, the magnetic lock is magnetized, and the left and right doors are sucked and locked by the magnetic force of the magnetic lock, and both the left and right doors remain in the closed state;

[0010] S3. When both the left and right doors are closed, if an external opening instruction is received, the normally closed node of the relay is disconnected, the circuit is disconnected, the magnetic lock is demagnetized, the magnetic lock loses its magnetic force, and both the left and right doors can be opened.

[0011] Compared with the prior art, the beneficial effects of the present invention at least include:

[0012] The synchronous opening and closing of double doors realized by the magnetic electronic access control of the present invention is easy to implement, has low cost, and can be used for the control of the synchronous opening and closing of any double doors, such as intelligent containers with double doors.

[0018] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following will combine the drawings and specific embodiments to detail the technical solutions of the present invention. It should be noted that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] Embodiment 1

[0020] As Figure 1 shown, the present invention provides a method for realizing the synchronous opening and closing of double doors by magnetic electronic access control, including a regulated DC power supply 101, a left door node 102, a right door node 103, a relay 104, and a magnetic lock 105 connected in series in sequence. The regulated DC power supply 101 provides a working power supply with stable DC voltage for the magnetic lock 105. Both the left door node 102 and the right door node 103 are closed when the door is closed and open when the door is opened. The external opening instruction controls the opening and closing of the normally closed node of the relay 104.

[0021] Embodiment 2

[0022] As Figure 2 shown, the working principle of the synchronous opening and closing of double doors realized by the magnetic electronic access control of the present invention is as follows:

[0023] 1. When either the left or right door is opened, the circuit is disconnected, the magnetic lock loses magnetism, and both the left and right doors are in the open state.

[0024] 2. When both the left and right doors are closed, if no external door opening instruction is received, the circuit is closed, the magnetic lock is magnetized, and the left and right doors are sucked and locked by the suction force of the magnetic lock, and both the left and right doors remain in the closed state.

[0025] 3. When both the left and right doors are closed, if an external door opening instruction is received, the normally closed node of relay 104 is disconnected, the circuit is disconnected, the magnetic lock loses magnetism, the magnetic lock loses suction, and both the left and right doors can be opened.

[0026] The synchronous opening and closing of double doors by the magnetic electronic access control of the present invention is easy to implement and has a low cost, and can be used for the control of the synchronous opening and closing of any double doors, such as the intelligent container with double doors.

[0027] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
