[0002] Commercial freezers, positioned at the end of the refrigerated and frozen product sales chain, play a crucial role in the sale of these products. They not only provide an ideal low-temperature storage environment, effectively maintaining the freshness and taste of food, but also enhance display appeal through their professional design, thereby effectively promoting product sales. Widely used in stores and restaurants, commercial freezers ensure food quality and increase operational efficiency, making them indispensable equipment in the commercial sector. However, many freezers currently on the market operate offline, and their sales and replenishment status can only be statistically analyzed retrospectively through merchants' purchase, inventory, and sales records. This information lag makes it difficult for product suppliers, distributors, and users to grasp real-time market sales dynamics.

[0003] With the development of IoT technology, wireless sensing, image recognition, and remote networking technologies can be applied to achieve intelligent upgrades and transformations of commercial freezers. After intelligent upgrades, commercial freezers can provide owners, suppliers, and distributors with an effective intelligent management system.

[0004] This invention addresses current market demands by proposing an intelligent freezer extension device. By implementing this invention, ordinary commercial freezers can be transformed into intelligent freezers with remote management and intelligent detection capabilities. The management platform can use this intelligent freezer extension device to monitor freezer temperature, door opening and closing events, changes in contents, and fault alarms such as power outages in real time. It can also sample and identify consumer characteristics. Utility Model Content

[0020] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0021] This utility model proposes an intelligent expansion device for freezers, which is installed on the back of commercial freezers to upgrade and transform ordinary commercial freezers into intelligent freezers that can be remotely networked and managed. Figure 1 A schematic diagram of a freezer after the aforementioned intelligent expansion device has been installed is provided. As shown in the diagram, the intelligent expansion device includes a mounting base plate A1 with a concealed wiring channel inside. A power adapter box A2 and a control box A3 are mounted on the back of the mounting base plate A1. The power adapter box A2 is connected to the 220V AC power supply of the freezer's location via a plug and power cord, and the freezer's original power cord is also drawn from the power adapter box A2. The control box A3 contains a control board used to collect, process, and report real-time operating information of the freezer. Two mounting holes A4 are located on each side of the mounting base plate A1 for mounting the intelligent expansion device to the back of the freezer using bolts. Expansion brackets A5 and A6 are mounted on top of the mounting base A1. Expansion bracket A5, facing the front of the freezer, is equipped with a top-view camera. Its imaging direction is aimed at the goods inside the freezer, and it uses a fisheye camera with a wide-angle view. Under the control of the control board, it captures images of the goods inside the freezer through the glass sliding door above the freezer. Expansion bracket A6, also facing the front of the freezer, is equipped with a door open / close detector for real-time monitoring of the sliding door's open / closed status. Expansion brackets A5 and A6 are mounted on top of the mounting base A1 via a slot structure, and the joint has wiring holes for connecting signal lines between the camera, door open / close detector, and control board. Expansion bracket A5 is mounted in the middle of the top of the mounting base A1, and one expansion bracket A6 is mounted on each side of the top of the mounting base A1. Figure 2 A front view is shown after the expansion bracket is assembled on the mounting base A1. The door opening / closing detector can be a magnetic door switch. A heads-up camera can be further mounted on the expansion bracket A5 for consumer sampling, i.e., by collecting images of consumers selecting goods in the freezer, the images are reported to the management platform for consumer characteristic analysis and extraction to promote sales.

[0022] The electronic functional block diagram of the intelligent expansion device for the freezer is as follows: Figure 3As shown, the main control processor, wireless communication unit, sensor unit, camera unit, and power supply interface circuitry are integrated on the control board, which is a PCB circuit board. The wireless communication unit is responsible for accessing the communication network via WiFi or mobile communication technology to connect to the remote management platform, and is electrically connected to the main control processor through PCB traces. The main control processor is responsible for controlling the collaborative work of each functional unit, processing the data collected by the sensor units locally, and reporting the processing results to the management platform through the wireless communication unit. The sensor units include the aforementioned camera and door open / close detector, as well as a temperature sensor. This temperature sensor uses infrared thermometry and is mounted on the aforementioned expansion bracket A6 to detect the internal temperature of the freezer. The power supply includes an AC / DC conversion circuit, an emergency battery, and its charging and discharging management circuit. The battery is a rechargeable lithium battery used to provide temporary emergency monitoring and management during power outages.

[0023] The main control processor performs local processing on the data collected by the sensing unit, including determining whether the data reported by the temperature sensor is within the normal range. If it exceeds the range, a temperature alarm event is generated and reported immediately; otherwise, the freezer's working status is only reported periodically. For the door opening signal reported by the door open / close detector, the main control processor can convert it into a trigger signal to control the camera and temperature sensor to wake up from the sleep state and enter the working state. Conversely, the door closing signal triggers the camera and temperature sensor to re-enter the sleep state.
