Description

A Refrigerator Auxiliary System Based on Internet of Things

technical field

The utility model relates to a household electronic product, in particular to a household electrical appliance which can automatically identify and weigh food, provide scientific and reasonable recipes and can be accessed remotely, in particular to a refrigerator auxiliary system based on the Internet of Things.

Background technique

Refrigerator is a product of modern society, which brings a lot of convenience to our daily life. Now almost every family has one or more refrigerators. With the improvement of life quality, people pay more and more attention to food health issues. However, with the With the development of society, people's pace of life is accelerating, work pressure and other factors make it difficult for many people to have the energy to remember what food is in the refrigerator, how long these foods have been stored, and whether various foods are directly incompatible. Some unhealthy growth and development caused by the food in the refrigerator, and even cause diseases, etc. Therefore, providing scientific and reasonable diet for people is also a problem to be solved urgently.

At present, most of the food identification in the refrigerator uses RFID radio frequency cards or internal scanning probes to display the food storage conditions in the refrigerator on the external display. Due to the use of a large number of RFID radio frequency cards or cameras, the cost is very high, and the food storage situation in the refrigerator can only be checked at home, which has certain limitations.

Utility model content

In order to solve the above-mentioned technical problems, the utility model provides a refrigerator auxiliary system based on the Internet of Things. The utility model connects the refrigerator to the Internet, so that users can perform remote viewing and control through the Internet.

The technical scheme adopted by the utility model is: a refrigerator auxiliary system based on the Internet of Things, the refrigerator auxiliary system includes a data acquisition module and a central processing system module arranged inside the refrigerator body, and the central processing system module and The touch display module for human-computer interaction located outside the refrigerator body is connected, the data acquisition module includes a load cell, a laser scanner and a wireless transmission device, and the load cell is connected to the wireless transmission device through a line pipeline , the weighing sensor, the laser scanner and the wireless transmission device are all connected to the central processing system module, and the central processing system module communicates bidirectionally with the remote client through the network communication system.

Central processing system module described in the utility model adopts Contex_A8 processor, WinCE6.0 operating system.

The remote client described in the utility model includes a mobile phone, a computer or a tablet computer.

Network communication system described in the utility model is GPRS communication module, WIFI module, Ethernet module.

Beneficial effects of the utility model: the utility model has a simple structure, does not need to use equipment such as RFID radio frequency cards or internal scanning heads, and the label cost is low, which greatly saves costs. For food information, the utility model can record food information from the food source (refrigerator) in the user's home, and recommend a scientific and reasonable diet, which can not only make full use of the nutritional value of the food, but also benefit the health of the body. In addition, remote computer and mobile phone access enables remote access to food information in the refrigerator at home, which is convenient for users to check food purchases and food collocations.

Detailed ways

As shown in the figure, a refrigerator auxiliary system based on the Internet of Things, the refrigerator auxiliary system includes a data acquisition module and a central processing system module arranged inside the refrigerator body, and the central processing system module is connected with the refrigerator body outside The touch display module connection for human-computer interaction, the data acquisition module includes a load cell, a laser scanner and a wireless transmission device, the load cell is connected to the wireless transmission device through a line pipeline, the load cell, Both the laser scanner and the wireless transmission device are connected with the central processing system module. The central processing system module communicates bidirectionally with the remote client through the network communication system. The central processing system module adopts a Contex_A8 processor, WinCE6.0 operating system, and the remote client The terminal includes a mobile phone, a computer or a tablet computer, and the network communication system is a GPRS communication module, a WIFI module, and an Ethernet module.

In the process of using the utility model, first paste the produced barcode on the food or the food container, open the refrigerator door to scan the barcode and put it in, the weighing sensor at the bottom will change, through the HX1117AD conversion chip, through the STM32VET6 Processing, the amount of change before and after the weight of the food put into the load cell is transmitted wirelessly to the central processing system module through RF24L01. The central processing system module uses the Contex_A8 processor, runs the WinCE6.0 operating system, and stores the received food information into the database. On the touch display module, you can check the current food information in the refrigerator and select recommended recipes (including required recipes). The amount of ingredients and the operation steps), food shortage and relative restraint reminders and other operations. Simultaneously, the central processing system module also constantly performs handshake connection with the computer connected to the Internet through the GPRS module, and updates the food data information stored in the computer after the handshake is successful. The update of the software data of the computer terminal is that the terminal actively connects with the central processing system module, so open the software and click the connection button to get the latest data information. In addition, there is also a mobile phone SMS access part in the remote access. Any mobile phone can edit "*this mobile phone number* + private dining bar" and send it to the SIM card on the GPRS module to receive the current food information in the refrigerator. the
