Detailed Description
(example 1)
Referring to fig. 1 to 4, the present invention has a doorframe 1 and a door body 2; one side of the door body 2 is connected with the door frame 1 through a plurality of connecting pieces 3; the connector 3 comprises a connecting piece 31 made of shape memory alloy; a first bent portion 311 and a second bent portion 312 integrally formed with the connecting piece 31; the first bending part 311 is fixedly connected with the door frame 1, and the second bending part 312 is fixedly connected with the door body 2; the connecting sheet 31 is connected with the power module 4 through an electric wire; when the connecting sheet 31 is not electrified, the door body 2 is in a closed state on the door frame 1; when the connecting piece 31 is energized, the first bent portion 311 and the second bent portion 312 change in angle, and the door 2 is opened on the door frame 1. The principle is that the power module 4 can electrify the connecting sheet 31, the connecting sheet 31 can generate heat due to resistance after the connecting sheet 31 is electrified, the connecting sheet 31 can change in shape in the heating process, and the connecting sheet 31 can recover to the original shape after the temperature is reduced after the power is cut off.
Meanwhile, the system is also provided with an access control system 5; the access control system 5 is a face recognition access control all-in-one machine. The face recognition entrance guard all-in-one machine is electrically connected with the power module 4, and the entrance guard system 5 is used for controlling the electrification and the outage of the power module 4 according to a recognition result.
The face recognition entrance guard all-in-one machine is fixedly arranged on the door body 2. The circuit is connected and arranged in the door body, so that the hiding effect is achieved.
The access control system 5 is of the existing design, and the structure and the working principle thereof are not repeated here. The access control system 5 may be other access control devices, such as a password access control device and an identification card access control device, except the face recognition access control integrated machine in the embodiment.
The face recognition access control all-in-one machine can adopt most products on the market, and because the face recognition access control all-in-one machine is often used with the electronic lock cooperation, and the locking of electronic lock and relieving are all realized through the circular telegram, all have the control wiring end that the power supply switched on and switched off in the current face recognition access control all-in-one machine. The control terminal is connected to the connection piece 31 only by an electric wire.
Meanwhile, the working principle of the access control system 5 can refer to the patent numbers: 2012104788429, patent name: an access control system and a method for managing the authority of the access control system; reference may also be made to patent numbers: 2015203093794, patent name: description of an access control system.
In this embodiment, the face recognition all-in-one machine can adopt a Haokawav vision DS-K1T605 series face recognition all-in-one machine. Meanwhile, shape memory alloys have been used in many fields, and the basic principle of deformation by energization is well known.
The working process of the invention is as follows:
the face recognition entrance guard all-in-one machine controls the power supply module 4 to be powered on through recognition if the door opening condition is met; after the power is turned on, the connecting sheet 31 is a metal member having resistance, and thus generates heat under the action of current, and when the temperature reaches the phase change point, a form change occurs, that is, an angle change occurs in the first bending portion 311 and the second bending portion 312, and the door body 2 is opened. After the people got into, integrative chance of face identification entrance guard cuts off the power supply module 4 according to outside instruction or time delay control, and the connection piece 31 cooling is carried out the form once more and is changed and realize that the door body 2 closes.
(example 2)
Referring to fig. 5, an electronic lock 6 for locking is further arranged between the door body 2 and the door frame 1; the electronic lock 6 is electrically connected with the access control system 5 and is controlled by the access control system 5.
Other technical features are the same as those of embodiment 1.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
