[0015] like Figures 1 to 3 As shown, a refrigeration equipment energy-saving control system includes an Internet of Things cloud platform and a cabinet 2, wherein the cabinet 2 is provided with an LED lighting unit, and the cabinet is also provided with a camera 5, a night curtain lifting unit and a controller 1, wherein the LED lighting unit, the camera 5 and the night curtain lifting unit are all electrically connected to the controller 1, and the controller 1 is communicatively connected to the Internet of Things cloud platform.

[0016] In this embodiment, the controller 1 is connected to the physical network platform via a wireless network communication, and the camera is used to collect image information around the cabinet 2, and transmit the image information to the Internet of Things network cloud platform through the controller 1; the Internet of Things cloud platform identifies and determines the collected image information. When it is determined that someone is passing by, the Internet of Things cloud platform sends an instruction to the controller 1, so that the controller adjusts the brightness of the LED lighting unit and drives the night curtain lifting unit to move, so that the night curtain rises.

[0017] For those skilled in the art, the technical means of collecting image information through a camera and transmitting the image information to the IoT cloud platform for portrait recognition is a prior art. The announcement date is January 16, 2024, the patent number is "2023221707657", and the name is "A Home Security System Based on the Internet of Things". It discloses a monitoring system, an intelligent gateway, a mobile terminal and an IoT cloud platform. The monitoring system includes a camera, an infrared sensor, an intelligent voice broadcast and an intelligent display. The camera is connected to the IoT cloud platform through an intelligent gateway. The IoT cloud platform includes an intelligent recognition component, which includes face recognition and clothing recognition. Therefore, it is a prior art to perform portrait recognition on images collected by the camera through the IoT cloud platform.

[0018] like Figure 1 to Figure 2 As shown, the top of the cabinet is provided with an upper cover plate 6, and the upper cover plate 6 is provided with a placement groove, and the camera 5 is fixed in the placement groove, and the camera 5 is electrically connected to the controller 1 through a USB interface. The camera 5 is fixedly connected to the placement groove by screws, and the camera 5 includes a lens, an image sensor, an onboard circuit and a signal pin. In this embodiment, the camera is preferably a camera circuit board solution based on Cypress CY7C68013A. The camera side CY7C68013A hardware circuit board is connected to the camera sensor module of the tested application. The circuit board provides 3.3v power for the camera, configures initialization parameters for the sensor through the IIC bus, and transmits image data to the controller 1 through the USB 2.0 high-speed interface. The controller 1 is a single-chip microcomputer or a PLC, and is preferably a single-chip microcomputer in this embodiment.

[0019] The night curtain lifting unit includes a motor 3, a rotating shaft 4 and a night curtain. The night curtain is wound on the rotating shaft 4. The bottom of the rotating shaft 4 is flush with the top of the cabinet, and a bearing is provided at one end of the rotating shaft 4. The bearing is fixed to one end of the bottom of the upper sealing plate 6. The other end of the rotating shaft 4 is fixedly connected to the output shaft of the motor 3. The motor 3 is fixed to the other end of the bottom of the upper sealing plate 6, and the motor 6 is electrically connected to the controller.

[0020] The controller 1 drives the motor 3 to rotate forward or reverse to drive the shaft to rotate forward or reverse, thereby realizing the unfolding or rolling up of the night curtain. In this embodiment, one end of the night curtain is fixedly connected to the shaft, and the other end of the night curtain is provided with a counterweight. For example, when the motor 3 rotates forward, the night curtain rotates out from the shaft 4, and under the action of the gravity of the counterweight, the night curtain gradually unfolds from the top of the cabinet 2 to the bottom of the cabinet 2, thereby keeping the cabinet 2 warm and moisturizing, saving energy consumption of the refrigerator or display cabinet. The night curtain is preferably a transparent night curtain, so that after the night curtain is unfolded to cover the refrigerator or display cabinet, it does not affect the display of the goods in the cabinet 2.

[0021] For another example, when the motor 3 rotates in the reverse direction, the rotating shaft 4 rotates to roll up the night curtain, so that the night curtain moves from the bottom end of the cabinet 2 to the top end of the cabinet 2, making it easier for customers to take goods from the refrigerator or display cabinet.

[0022] Night curtains can also keep food in the cabinet cold. When working normally, night curtains can not only keep the temperature stable, but also save energy. Night curtains save energy by preventing the air in the display cabinet from diffusing into the sales floor. When the night curtains are opened, the cold air in the cabinet body 2 will be replaced by the warm air in the sales floor. In order to keep the display cabinet working normally, the warm air must be cooled quickly, which means that the compressor in the display cabinet has to work harder and waste energy continuously. The use of night curtains can effectively prevent the loss of cold air and reflect the heat outside the refrigerator, which can save energy.

[0023] The LED lighting unit includes an LED lamp 8 and a photosensitive sensor 7. The photosensitive sensor 7 is electrically connected to the controller 1. The controller 1 is electrically connected to the LED lamp 8. The LED lamp 8 is a light strip. The side panels in the cabinet are provided with light slots. The light strip is fixed in the light slots. The photosensitive sensor 7 is used to detect the brightness of the LED lamp in the cabinet 2, and convert the brightness value into an electrical signal and transmit it to the controller 1, so that the controller 1 can adjust the brightness of the LED lamp.

[0024] The controller 1 stores a first brightness value and a second brightness value, the first brightness value is smaller than the second brightness value, when no one approaches the cabinet 2, the controller 1 adjusts the brightness of the LED lamp to the first brightness value, at which time the brightness of the LED lamp is lower, reducing power consumption and saving energy.

[0025] When the image information collected by the camera contains a portrait, the controller 1 obtains instructions from the IoT cloud platform to increase the brightness of the LED lamp to a predetermined brightness. When the photosensitive sensor 7 detects that the brightness inside the cabinet reaches the predetermined brightness, the controller 1 stops adjusting the brightness of the LED lamp.

[0026] The specific working process of a refrigeration equipment energy-saving control system is as follows: when no one approaches the cabinet 2, the LED lighting unit in the cabinet 2 is low-brightness lighting, and at the same time, the night curtain of the night curtain lifting unit is in a pulled-down state, which plays the role of energy saving, freshness preservation, and energy saving;

[0027] The camera 5 collects images around the refrigerator or display cabinet, and transmits the collected images to the IoT cloud platform through the controller. After the IoT cloud platform determines that someone is present, the IoT cloud platform drives the night curtain lifting unit through the controller to pull up the night curtain, and at the same time increases the brightness of the LED lighting unit, so that customers can choose the goods in the refrigerator or display cabinet. When the camera does not detect a person, the controller reduces the brightness of the LED lighting unit, and at the same time, the night curtain of the night curtain lifting unit is in a pulled-down state, which plays the role of energy saving, freshness preservation, and energy saving.

[0028] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
