when the refrigerator has an overtemperature phenomenon, the operation panel is used for combining temperature and humidity data in the refrigerator and temperature and humidity data outside the refrigerator to calculate and obtain a temperature and humidity compensation value WB; the refrigeration power of the refrigerator is regulated in an auxiliary mode according to the temperature and humidity compensation value WB; the method comprises the following specific steps:
acquiring the temperature and humidity storage requirement of an article, marking the target temperature as M1, and marking the target humidity as W1; acquiring temperature and humidity data in the refrigerator and temperature and humidity data outside the refrigerator;
marking the internal temperature as M2 and the internal humidity as W2; the external temperature is marked as M3, and the external humidity is marked as W3; calculating to obtain a temperature and humidity compensation value WB by using a formula WB= (M2-M1) × (M3-M2) ×b1+ (W1-W2) × (W2-W3) ×b2, wherein b1 and b2 are coefficient factors;
setting a plurality of refrigerating power thresholds of the refrigerator, wherein each refrigerating power threshold corresponds to a preset temperature and humidity compensation value range; matching the temperature and humidity compensation value WB with all preset temperature and humidity compensation value ranges to obtain corresponding refrigeration power threshold values and marking the refrigeration power threshold values as Wm; the operation panel is used for adaptively adjusting the refrigerating power of the refrigerator to Wm so as to control the temperature and humidity in the refrigerator;
step four: after the articles are stored in the refrigerator, reading article information of the articles in the refrigerator through an RFID reader-writer arranged in the refrigerator cavity, and storing the article information in a database to generate an article list; a user invokes temperature and humidity data and article information of the refrigerator through an operation panel;
step five: the method comprises the steps that a user inquires data of an operation panel through an intelligent terminal, wherein the data inquiry instruction is used for acquiring temperature and humidity data in a refrigerator and corresponding inventory persons and consignees of articles;
the operation panel performs tracing processing on the data query instruction and verifies whether the data query instruction is legal or not; the tracing process is performed by acquiring an access IP for sending a data query instruction; the method comprises the following specific steps:
when an external IP tries to access an operation panel, firstly performing white list verification on the access IP, and if the access IP is in the white list range and the permission is allowed, judging that the data query instruction is legal;
if the access IP is not in the white list range, acquiring an access record of the access IP to perform FX analysis; the specific analysis steps are as follows:
acquiring an access record of the access IP within a preset time period; the access record carries the access time and whether the access is successful or not; counting the total number of times of access of the access IP as F1;
counting the successful times of the access IP access as Fb; performing time difference calculation on adjacent access time to obtain an access interval QTi; comparing the access interval QTi with a preset interval threshold;
counting the times that QTi is smaller than a preset interval threshold value as Y1; when the QTi is smaller than a preset interval threshold, obtaining the difference value of the QTi and the preset interval threshold and summing to obtain a difference total value YT;
calculating by using a formula FX= ƒ ×F1× (Fb×g1+Y1×g2+YT×g3), wherein g1, g2 and g3 are all preset coefficient factors; ƒ is a preset equalization coefficient;
comparing the access attraction factor FX with a preset attraction threshold; if FX is larger than a preset attraction threshold, judging that the data query instruction is legal; otherwise, carrying out access control on the access IP, and sending reminding information comprising the access IP to a mobile terminal associated with an operation panel so as to remind a manager of confirming whether the data inquiry instruction is legal or not; if the access is legal, allowing the access; otherwise, access is denied.
2. The method for managing an RFID temperature-induced intelligent refrigerator of claim 1, further comprising: according to the specific environment accessed by the operation panel, setting the network IP allowed to access the operation panel and the access authority owned by the network IP, and generating a network access white list specific to the operation panel.
3. The method for managing an RFID temperature-induced intelligent refrigerator of claim 1, wherein the article information is read by the RFID reader after the article is taken out of the refrigerator, the corresponding article information stored in the database is cleared, and the article list is updated.
4. The method for managing the RFID temperature-imported intelligent refrigerator according to claim 1, further comprising a wireless communication interaction module, wherein the wireless communication interaction module is connected with the operation panel and used for carrying out interactive connection with the management equipment through a wireless communication network, so that temperature and humidity data in the refrigerator are timely connected with the management equipment to form closed-loop management.
