As mentioned above, the sliding door lock of this application is not controlled by electronic signal, but can make first contact pin and second block subassembly extension or shorten according to the change of temperature to non-contact unblanking has been realized. Referring first to the sliding door lock of the present application, as shown in fig. 4-5, the sliding door lock in the sliding door is further configured to: the sliding door lock comprises a first clamping component, a second clamping component and a first contact pin; the first clamping component is L-shaped and is connected with the door frame; the first contact pin is elastically connected with the doorframe in the horizontal direction through a first elastic component; the second clamping component is elastically connected with the sliding door in the vertical direction through a second elastic component; the first clamping component and the second clamping component are arranged oppositely in the horizontal direction, and when the sliding door lock is locked, the first clamping component and the second clamping component are clamped in the horizontal direction, so that the sliding door is prevented from moving in the direction away from the door frame; the first opposite surface of the second clamping component is an inclined surface, and the first opposite surface refers to the side surface closest to the first clamping component in all the side surfaces of the second clamping component when the sliding door lock is unlocked; a first slot is arranged on the first opposite surface; a sliding sheet is covered on the first opposite surface and used for covering the first slot; the first pin and the first slot are in the same position in the vertical direction; the first elastic part or the first contact pin is made of a first temperature-sensitive material, so that the first elastic part or the first contact pin is shortened at a first temperature and is extended at a second temperature, wherein the first temperature is lower than the second temperature; the second elastic part or the second clamping assembly is made of a second temperature-sensitive material, so that the second elastic part or the second clamping assembly extends at a first temperature or a second temperature and shortens at a third temperature, wherein the third temperature is higher than the second temperature. Further, the first temperature-sensitive material is a copper-zinc-aluminum memory alloy, and the second temperature-sensitive material is a nickel-titanium memory alloy. Further, the first elastic component and the second elastic component are both springs. Thereby when the temperature drops to first temperature, first contact pin is inserted from the second block subassembly to give the degree of freedom of second block subassembly in the vertical aspect, rise the temperature to the third temperature again, so that the second block subassembly shortens to with first block subassembly on the horizontal aspect on the vertical direction non-intersect, thereby the push-and-pull door lock is opened.

As described in the step S1-3, acquiring an infrared signal of a preset infrared detector for performing indoor infrared detection; analyzing the infrared signal according to a preset signal analysis method to obtain an infrared analysis result; wherein the infrared analysis result comprises the presence or absence of an adult; and judging whether the infrared analysis result is that no adult exists. People are constant temperature creatures and can emit infrared rays. It can be ascertained by infrared detection whether it is likely to be an adult human body. Since pets, infants, fires, etc. can also emit infrared light, the present application analyzes the infrared signal to determine if an adult is present. The analysis method includes, for example, acquiring a shape of the image of the infrared signal with respect to the environmental signal, and determining whether the shape corresponds to a human shape of an adult, and if not, determining that no adult exists.

As described in the above step S4-6, if the infrared analysis result indicates that no adult exists, acquiring a balcony image by using a preset first camera; the first camera is arranged at a high place where balcony panorama can be collected, and the first camera is opened by default; analyzing the balcony image to obtain an image analysis result, wherein the image analysis result comprises the existence of a person or the nonexistence of a person; and judging whether the image analysis result is a human. The first camera is a normally open camera, and the resolution ratio is lower, so that the cost is saved, the energy is saved, and the labor waste is reduced. The function of the first camera is to preliminarily determine whether a person is present on the balcony. If not, the channel opening operation is not needed; otherwise, further judgment is needed. The image analysis may be performed in any feasible manner, and will not be described herein again.

As described in the above step S7-8, if the image analysis result indicates that a person is present, acquiring the position of the person in the balcony; starting a preset second camera, rotating the second camera to a position facing the person in the balcony image, and performing video acquisition on the person in the balcony image by using the second camera to obtain a first video; the second camera is arranged on the sliding door, the second camera is closed in a default mode, the resolution ratio of the second camera is higher than that of the first camera, and the second camera is arranged to be rotatable. When someone is on the balcony, in order to prevent to be died on the balcony by the lock, this application judges earlier whether the balcony people intends to enter the door, opens the push-and-pull door lock under the circumstances that the intention entered the door. The second camera collects the obtained first video according to the basis of judging whether the balcony people intend to enter the door. The second camera is arranged on the sliding door, the second camera is closed in a default mode, and the resolution ratio of the second camera is higher than that of the first camera, so that the calculation precision is improved, and the judgment accuracy is improved. The first camera and the second camera are separately arranged, and the difference of the resolution ratio is arranged, so that the whole system is favorable for cost reduction and calculation power saving, and the accuracy of the calculation result is still ensured.

As described in step S9-10, extracting multiple frame pictures from the first video, and inputting the multiple frame pictures into a preset intention recognition model for processing, so as to obtain a recognition intention output by the intention recognition model; the intention recognition model is obtained by training based on a preset neural network model and by utilizing preset sample data, and the sample data consists of a plurality of training pictures and intentions corresponding to the plurality of training pictures; the identified intent comprises an intended entry or an intended non-entry; and judging whether the identification intention is an intention to enter the door. The multiple frame pictures are extracted from the first video, so that the sequential relation in time is realized, and whether a balcony person has the intention of entering the door or not can be reflected. For example, when the multiple frame pictures show that the balcony people directly move towards the sliding door, it can be determined that the person intends to enter the door (e.g., the person is reflected in the frame pictures, that is, the area occupied by the balcony people in the multiple frame pictures is larger and larger). The method and the device analyze a plurality of frame pictures by using a meaning recognition model obtained based on neural network training so as to obtain recognition intentions. Wherein the neural network may be any feasible network, such as a convolutional neural product network, etc.

As described in step S11, if the intention is to enter the door, the temperature controller preset in the room is controlled to decrease the room temperature from the current second temperature to the first temperature for the first time. The temperature controller is, for example, an air conditioner. The purpose of reducing the indoor temperature from the current second temperature to the first temperature is to enable the first inserting pin of the sliding door lock to be pulled out of the second clamping component, so that the second clamping component obtains the degree of freedom in the vertical direction, and the first step of unlocking is completed.

As described in step S12, the temperature controller is controlled to increase the indoor temperature from the first temperature to a third temperature for a second time, so that the lock of the sliding door is opened and the corresponding channel of the sliding door is opened. The indoor temperature is increased to a third temperature from the first temperature, and the purpose is to enable the second clamping component to be reduced in the vertical direction so as to be staggered with the first clamping component in the horizontal direction, so that the second clamping component can freely move in the horizontal direction, and therefore the opening of a lock of the sliding door is completed, and a channel corresponding to the sliding door is opened. Further, a spring is arranged between the sliding door and the door frame, the spring is compressed when the sliding door is locked, and after the sliding door is unlocked, potential energy of the spring is released so as to push the sliding door away from the door frame.

The first temperature-sensitive material and the second temperature-sensitive material can be any feasible material, such as a memory alloy material, for example, a copper-zinc-aluminum memory alloy, a NiTi memory alloy, and the like. The phase change point of the copper-zinc-aluminum memory alloy can be adjusted within the range of-100 ℃ to 300 ℃, so that the phase change point can be set near room temperature by adjusting the component proportion. The transformation point of the NiTi memory alloy can be finely adjusted to 30-50 degrees. Specifically, the phase transition point of the first temperature sensitive material is lower than room temperature (for example, 25 degrees), and the phase transition point of the second temperature sensitive material is higher than room temperature. Then, by means of processing, the length of the first elastic member 5 or the first pin 3 at room temperature (which can be regarded as the second temperature) is longer, and the length at the phase transition point (i.e. the first temperature) is shorter, so that the lengths at different temperatures are memorized. In contrast to the first temperature-sensitive material, the second temperature-sensitive material is processed to make the length of the second elastic member 7 or the second engaging member 2 at room temperature (which may be regarded as the second temperature) shorter and the length at the phase transition point (i.e. the third temperature) longer, so as to memorize the lengths at different temperatures. Wherein the first temperature is for example 10-23 degrees, for example 15 degrees. The second temperature is for example 15-35 degrees, for example 25 degrees. The third temperature is, for example, 20-40 degrees, for example 30 degrees. All the above degrees refer to degrees centigrade.

In one embodiment, after the step S3 of determining whether the infrared analysis result is the absence of an adult, the method includes:

s31, if the infrared analysis result shows that an adult exists, when a preset pressure sensor senses a pressure signal, starting the second camera so as to acquire a first image of the position of the pressure sensor by using the second camera; the pressure sensor is arranged on the ground of a balcony which is away from the sliding door by a preset distance in advance;

s32, performing face recognition processing on the first image by adopting a preset face recognition technology to obtain a face recognition result, and judging whether the face recognition result is in a preset authority list or not;

and S33, if the face recognition result is in a preset authority list, reminding an indoor person to open the sliding door by using a preset voice playing device.

As mentioned above, the push-and-pull door is reminded of people in a room to open by utilizing the preset voice playing equipment. When an adult exists indoors, if the temperature change method is used for opening the door, discomfort can be caused to the adult indoors. Therefore, the infrared analysis result is in the time of the existence of the adult, and when the preset pressure sensor senses the pressure signal, the second camera is opened, so that the second camera is utilized to collect the first image of the position where the pressure sensor is located. In order to prevent people on the balcony from being maliciously invaded, a preset face recognition technology is adopted to perform face recognition processing on the first image so as to obtain a face recognition result, and whether the face recognition result is in a preset authority list or not is judged; and if the face recognition result is in a preset authority list, reminding an indoor person to open the sliding door by using preset voice playing equipment. Under the prerequisite of guaranteeing indoor people's safety and comfort level, realized the control to the passageway.
