DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Referring to FIG. 1 , it is a schematic diagram of the structure of a locker provided by an embodiment of the present invention under a first preferred implementation mode. The embodiment of the present invention provides a locker 10, comprising: a cabinet body 11, a glass cabinet door 12, a human body sensing device 13, an infrared sensor 14 and a controller 15. It should be noted that the locker 10 can be used in a variety of scenarios to store different types of items, such as a wine cabinet, a medicine cabinet, a commodity cabinet, etc.

Specifically, the cabinet 11 is provided with an article accommodating cavity for storing articles. The article accommodating cavity can be set as a plurality of storage layers, a plurality of storage compartments, etc., or other formats according to user needs, which will not affect the beneficial effects of the present invention.

The light transmittance of the glass door 12 is adjustable. Specifically, the glass door 12 is composed of light-transmitting glass and an adjustable light-transmitting film, preferably composed of two layers of light-transmitting glass and one layer of adjustable light-transmitting film, between the two layers of light-transmitting glass is a vacuum cavity, and the adjustable light-transmitting film is sandwiched between the two layers of glass, and the controller 15 outputs a corresponding electrical signal to control the light transmittance of the adjustable light-transmitting film.

The human body sensing device 13 is arranged on the glass cabinet door 12, and is used to detect whether there is human activity in the target area; the target area is an area formed by a preset distance threshold from the cabinet body. The specific installation position of the human body sensing device 13 can be set according to actual conditions, for example, it can be installed on the upper left side of the door body, so as to more comprehensively sense the human activities around the locker.

The infrared sensor 14 is arranged on the glass cabinet door to detect the distance between the person in the target area and the glass cabinet door in real time. The specific installation position of the infrared sensor 14 can be set according to actual conditions, for example, it can be installed on the right side above the door body.

The controller 15 is connected to the glass door 12 , the human body sensing device 13 and the infrared sensor 14 respectively, and controls the light transmittance of the glass door 12 by exchanging information with the human body sensing device 13 and the infrared sensor 14 .

Specifically, referring to FIG2 , it is a flowchart of the work performed by the controller of the locker in the first preferred implementation mode according to the embodiment of the present invention. The controller 15 is used to perform steps S11 to S13:

S11, obtaining the detection result of the human body sensing device;

S12, when there is human activity in the target area, controlling the infrared sensor to detect the distance between the person in the target area and the glass cabinet door in real time as the human distance;

S13, adjusting the light transmittance of the glass cabinet door according to the distance between the personnel.

In another implementation manner, in step S12, that is, after obtaining the detection result of the human body sensing device, the controller is further configured to execute step S14:

S14. When there is no human activity in the target area, control the current light transmittance of the glass cabinet door to be a preset minimum light transmittance.

In the embodiment of the present invention, after the locker 10 is powered on, the human body sensing device 13 starts to operate, performs real-time detection of human activities within a certain distance around the locker 10, and feeds back the detection results to the controller 15. When human activities are detected around the locker 10, the controller 15 starts the infrared sensor 14 to perform distance detection, detects the distance between the human around the locker 10 and the locker 10, and then adjusts the light transmittance of the glass door 12 according to the human distance. When no human activities are detected around the locker 10, the light transmittance of the glass door 12 is adjusted to the preset minimum light transmittance Q0.

It can be understood that the specific values of the preset minimum transmittance Q0 and the preset distance threshold L0 can be set according to actual conditions and are not specifically limited here.

The embodiment of the present invention provides a locker, which is provided by setting the door body of the locker as a glass door with adjustable light transmittance, installing a human body sensing device to detect human activities, and an infrared sensor to detect distance. After the locker is powered on, when human activities are detected in the target area, the infrared sensor is controlled to detect the distance between the human in the target area and the glass door in real time as the human distance; according to the human distance, the light transmittance of the glass door is adjusted. By adopting the technical means of the embodiment of the present invention, by detecting the human activities and human distance around the locker, when no person is close to the locker, the light transmittance of the glass door is the lowest, thereby effectively protecting the privacy of the user; when a person is detected to be close to the locker, the light transmittance of the glass door is controlled according to the distance of the person, so that the user does not need to open the door to view the items in the cabinet, which is convenient for the user to use; and it will not cause fluctuations in environmental factors such as temperature and humidity in the cabinet, effectively ensuring the storage conditions of the items stored in the cabinet, and will not cause unnecessary energy loss, thereby providing a good user experience for the user.

As a preferred embodiment, see FIG3 , which is a flowchart of the work performed by the controller of the locker in the embodiment of the present invention under the second preferred embodiment. The embodiment of the present invention is further implemented on the basis of the above embodiment, wherein step S13, that is, adjusting the light transmittance of the glass cabinet door according to the distance of the person, specifically includes steps S131 to S133:

S131, determining, according to the personnel distance, a distance interval in which the personnel distance is located as a target distance interval;

S132, determining the transmittance corresponding to the target distance interval according to the preset correspondence relationship between the distance interval and the transmittance as the target transmittance;

S133: When the personnel distance is within the target distance interval within a preset time period, adjust the current light transmittance of the glass cabinet door to the target light transmittance.

Specifically, in an embodiment of the present invention, the distance value within the target area, that is, the distance value less than the preset distance threshold L0, is pre-divided into multiple distance intervals, and each distance interval is set to correspond to a transmittance size, and the size of the value within the distance interval is negatively correlated with the size of the transmittance, that is, the greater the distance, the smaller the transmittance.

When it is detected that there is human activity around the locker 10, the distance of the person is detected, and the distance interval in which the distance of the person is located is determined, and then the corresponding relationship between the distance interval and the transmittance is queried to obtain the transmittance corresponding to the currently determined distance interval, which is recorded as the target transmittance. Then, it is further determined whether the distance of the person has changed. If the distance of the person is within the distance interval within the preset time length t0, the current transmittance of the glass cabinet door 12 is adjusted to the target transmittance.

As an example, in an actual application scenario, see FIG4 , which is a flowchart of the work performed by the controller of the locker in the embodiment of the present invention under the third preferred implementation mode. The embodiment of the present invention is further implemented on the basis of the above embodiment, step S13, that is, adjusting the current light transmittance of the glass cabinet door according to the distance of the person, specifically includes:

When the personnel distance is less than or equal to the preset distance threshold and greater than a first distance threshold, controlling the light transmittance of the glass cabinet door to be a first light transmittance;

When the personnel distance is less than or equal to the first distance threshold and greater than a second distance threshold, controlling the light transmittance of the glass cabinet door to be a second light transmittance;

When the personnel distance is less than or equal to the second distance threshold, controlling the light transmittance of the glass cabinet door to be a third light transmittance;

Among them, the preset distance threshold is greater than the first distance threshold, the first distance threshold is greater than the second distance threshold; the third transmittance is greater than the second transmittance, the second transmittance is greater than the first transmittance, and the first transmittance is greater than the preset minimum transmittance.

Specifically, two distance thresholds are pre-set, namely, a first distance threshold L1 and a second distance threshold L2, so as to divide three distance intervals, namely, (0, L2], (L2, L1] and (L1, L0], wherein L0>L1>L2>0. Moreover, the transmittance corresponding to the distance interval (L1, L0] is the first transmittance Q1, the transmittance corresponding to the distance interval (L2, L1] is the second transmittance Q2, and the transmittance corresponding to the distance interval (0, L2] is the third transmittance Q3, wherein Q1<Q2<Q3.

When human activity is detected around the locker 10, the distance of the human is detected, and it is determined whether the human distance is in the distance interval of (0, L2], (L2, L1] or (L1, L0], the target distance interval is determined, and then the corresponding light transmittance is determined. Then, it is further determined whether the human distance is in the target distance interval for a period of time t0, that is, whether the timing t is greater than t0. If so, the light transmittance of the glass cabinet door 12 is adjusted.

By adopting the technical means of the embodiment of the present invention, a plurality of distance intervals are divided to determine the adjusted transmittance corresponding to the currently detected distance of the person, and when it is determined that the distance of the person has not changed significantly, the transmittance of the glass cabinet door is adjusted. This can not only effectively meet the user's demand for the transmittance of the glass cabinet door, but also avoid the frequent output of the controller's adjustment signal for the transmittance of the glass cabinet door, resulting in abnormal adjustment and the like.

As a preferred embodiment, see FIG5 , which is a schematic diagram of the structure of the locker in the second preferred embodiment of the present invention. The locker 10 also includes an ambient light brightness detection device 16 and an illuminator 17; the controller 15 is also connected to the ambient light brightness detection device 16 and the illuminator 17 respectively. The ambient light brightness detection device 16 is arranged inside the cabinet 11, and is used to start running under the control of the controller 15 to detect the ambient light brightness and feed back to the controller 15. The illuminator 17 is arranged inside the cabinet 11, and is used to start the controller of the controller 15 to realize the lighting of the cabinet environment.

Then, referring to FIG6 , it is a flowchart of the work performed by the controller of the locker in the fourth preferred implementation mode of the embodiment of the present invention. In step S133, that is, when the personnel distance is within the target distance interval within the preset time, after adjusting the current light transmittance of the glass cabinet door to the target light transmittance, the controller is further used to perform the following steps:

Determining whether the target distance interval is a minimum distance interval;

When the target distance interval is the minimum distance interval, controlling the ambient light brightness detection device to detect the current ambient light brightness in the cabinet;

If the ambient light brightness is less than or equal to a preset brightness threshold, the lighting lamp is controlled to be turned on;

If the ambient light brightness is greater than the preset brightness threshold, the lighting lamp is controlled to be in an off state.

In the embodiment of the present invention, when the user is in the target area but not in the closest distance interval to the locker 10, the user may only need to roughly understand the items in the locker, or the ambient light brightness of the locker is good, so that the user can easily check the items in the locker, and no additional supplementary light is needed. Therefore, it is only necessary to turn on the corresponding light transmittance according to the distance. When the user has approached the locker 10 and is in the closest distance interval to the locker 10, the user may need to see the items in the locker clearly, or the ambient light brightness of the locker is poor, causing the user to approach the locker to check. Therefore, the ambient light brightness detection device 16 is started to detect the ambient light brightness P in the locker, and the brightness threshold P0 is set as the judgment condition. When the ambient light brightness P is low, the lighting lamp 17 is started to supplement the brightness to facilitate the user to check.

In the application scenario of the above example, there are three distance intervals: (0, L2], (L2, L1] and (L1, L0]. When the user is in the distance interval (L2, L1] or (L1, L0], the controller 15 controls the glass cabinet door 12 to start the corresponding light transmittance. When the user is in the minimum distance interval (0, L2], after controlling the glass cabinet door 12 to start the corresponding light transmittance, the controller 15 further detects the ambient light brightness P in the cabinet, and when it is determined that P≤P0, controls the lighting 17 in the cabinet to start lighting.

Preferably, after the lighting lamp is controlled to be in the on state and lasts for more than a first preset time period t1, the lighting lamp is controlled to be in the off state to save power.

By adopting the technical means of the embodiment of the present invention, when a user approaches the locker to check the items in the locker, the lighting can be turned on in time to supplement the brightness, which is convenient for the user to check and improves the user experience.

As a preferred embodiment, see Figures 7 and 8. Figure 7 is a schematic diagram of the structure of the locker in the third preferred embodiment of the present invention; Figure 8 is a schematic diagram of the connection relationship between the controller and various devices of the locker in the present invention. The locker 10 also includes a face recognition device 18, which is arranged on the glass cabinet door 12.

Preferably, the face recognition device 18 can be integrated into the display module of the locker 10 and connected to the controller 15 to realize information exchange. During the application process, the user needs to enter the face of the user in advance and store it as an authorized person. In the subsequent use process, the face recognition of the people around the locker can be performed to determine whether the recognized face is an authorized person, and the result is fed back to the controller 15.

Referring to FIG9 , it is a flowchart of the work performed by the controller of the locker in the fifth preferred embodiment of the present invention. In the embodiment of the present invention, the controller 15 is used to perform steps S21 to S25:

S21, obtaining the detection result of the human body sensing device;

S22, when there is human activity in the target area, controlling the face recognition device to identify whether the person in the target area is a preset authorized person;

S23, if yes, controlling the infrared sensor to detect the distance between the person in the target area and the glass cabinet door in real time as the person distance; and

S24, adjusting the current light transmittance of the glass cabinet door according to the distance between the personnel;

S25: If not, control the current light transmittance of the glass cabinet door to be a preset minimum light transmittance.

Based on the above embodiments, the embodiment of the present invention can set a variety of scene modes according to the different use environments of the locker 10, such as a home living room, a supermarket, a bar, etc. In different modes, different user permissions can be set, such as administrators, visitors, etc. When the human body sensing device 13 detects the presence of human activities in the target area, the controller 15 first starts the face recognition device 18 to detect whether it is an authorized person. If it is an authorized person, the infrared sensor 14 is started to detect the distance between the person and the person, and the transmittance of the glass cabinet door 12 is determined according to the distance between the person and the person. If it is not an authorized person, the current transmittance of the glass cabinet door is controlled to be the preset minimum transmittance Q0 unchanged.

Specifically, when no one is walking around the locker, the light transmittance of the glass door 12 is adjusted to the minimum value Q0. When the human body sensing device 13 senses that there is a person walking around the locker 10 within a distance L0, the controller 15 immediately transmits the instruction to the face recognition device 18 to identify the person and confirm whether it is an authorized person. If it is not an authorized person, the original light transmittance Q0 is kept unchanged. If it is confirmed to be an authorized person, the result is fed back to the controller 15, and the controller 15 drives the infrared sensor 14 to start distance measurement. When the distance between the person is L1<L≤L0, timing is performed at the same time. If the distance interval remains unchanged within the preset time t0, the controller 15 adjusts the glass door 12 to the minimum value Q0. The transmittance of the glass door 12 is Q1. When the distance between the personnel is L2<L≤L1, if the distance interval remains unchanged within t0, the controller 15 adjusts the transmittance of the glass door 12 to Q2. When the measured distance is L≤L2, if the distance interval remains unchanged within t0, the controller 15 adjusts the transmittance of the glass door 12 to Q3. At the same time, the controller 15 starts the ambient light brightness detection device 16 to detect the ambient light brightness in the cabinet. If the ambient light brightness P＞P0, the lighting 17 in the cabinet will not be started. If the ambient light brightness P≤P0, the lighting 17 in the cabinet will be started and the start-up time will be detected. If it exceeds t1, the lighting 17 will be turned off.

Based on the embodiment of the present invention, when human activities are detected around the locker 10, by detecting whether the person is an authorized person and then adjusting the light transmittance of the glass door according to the distance of the authorized person, it is possible to prevent unauthorized persons from approaching to view the information of items in the locker, thereby better protecting the user's privacy and improving the user experience.

Referring to Fig. 10, it is a flow chart of a method for controlling the light transmittance of a glass door provided by an embodiment of the present invention.

This can not only effectively meet the user's demand for the transmittance of the glass cabinet door, but also avoid the frequent output of the controller's adjustment signal for the transmittance of the glass cabinet door, resulting in abnormal adjustment and the like.
