Background technique

In special places such as the Anti-Corruption Bureau of the Procuratorate, etc., the daily food and food of double-regulatory personnel need to be stored for a specified number of days, and the retained food can only be discarded after confirming that there is no problem with the food. The traditional management method is to store food in disposable containers, paste labels on the containers, and indicate the name of the shuanggui personnel corresponding to the food, storage time and other corresponding information. This kind of marking that can display the information of double-regulatory personnel has potential safety hazards. People with ulterior motives can easily find stored food, replace food, and other possible operations. In the traditional management method, there is also the way of using video surveillance to manage and store food. Video surveillance equipment can only confirm that a person arrives in a certain area from a large perspective, but the camera cannot see the details of the operation through concealed occlusion. When something goes wrong (such as when a preserved sample is lost) there is no direct evidence pointing to a suspect.

The working principle of the present invention is: put the food that needs to be preserved into a disposable container on the workbench, and use the RFID barcode inventory device to store the relevant information of the preserved food (including the name of the double-regulatory personnel, the type of food, the retention time, etc.) without contact written into a hidden RFID tag in the disposable vessel. The signal receiving range of the RFID reader covers the reserved food management area. Put the disposable utensils into the reserved food management area, and use RFID technology to exchange information between the RFID reader and the RFID tag in the reserved food management area. Normally, the RFID reader is in a dormant state. When someone enters or leaves the food storage management area, the infrared sensor senses the person's entry and exit, and transmits the signal to the industrial computer. The industrial computer controls the RFID reader and camera to start according to the signal. When the disposable utensils leave the illegally taken and stored food management area, the RFID reader generates a signal and transmits the signal to the industrial computer. The industrial computer controls the camera to take pictures and video, and controls the speaker to alarm and remind. During normal management, the RFID barcode inventory device is used to read the information of the RFID tag in the disposable container to manage the retained food.

The beneficial effects of the present invention are: the reserved food management system of the present invention effectively utilizes the RFID technology, and is suitable for the fields requiring preserved food management, such as the anti-corruption bureau of the procuratorate. The stored food can only be read and identified by a special RFID barcode inventory device, there is no need to post information signs, and the information cannot be tampered with or destroyed. It can effectively carry out video surveillance management on preserved food, and take photos, videos and other evidence preservation of people who enter the preserved food management area. The RFID reader has a sleep function and has a longer service life.
