[0031] This application provides a smart card-based temperature and humidity control method for warehouses, comprising: setting a smart card; unlocking control permissions based on the smart card, including setting a radio frequency (RF) signal for the smart card, wherein the RF signal uniquely corresponds to a feature code, the feature code is stored in a controller connected to a smart card reader; the controller reads the RF signal of the smart card, compares the RF signal with the feature code, and determines the permission range based on the comparison result; if the permission range includes temperature and humidity control, the temperature and humidity control program is invoked, the input control command is converted into a temperature and humidity device operation command, and input into the temperature and humidity device.

[0032] Figure 1 This is a schematic diagram of the temperature and humidity control process for the warehouse smart card in this application.
[0033] Please refer to Figure 1 As shown, S101 sets up a smart card and unlocks control permissions based on the smart card, including setting the radio frequency signal of the smart card. The radio frequency signal uniquely corresponds to a feature code, which is stored in a controller connected to a smart card reader.
[0034] The smart card is a radio frequency (RF) based magnetic card with an internal coil that can record signals. The RFID card requires configuration, including setting the RF signal of the smart card. This RF signal uniquely corresponds to a feature code, which is recorded in the controller and set during the configuration of the RF card.
[0035] The feature code corresponds uniquely to the radio frequency signal. Once the radio frequency signal is read, the feature code can be obtained based on the correspondence between the radio frequency signal and the feature code.
[0036] The smart card surface is also provided with a hidden code, which is a unique long string of characters. In this application, the hidden code is entirely composed of numbers, including: an algorithm code, a calculation bit code, a calculation code, a fill code, and a result code. The algorithm code is a random number, which can be set to a minimum and a maximum value and is a positive integer, used to represent the algorithm used to calculate the result code. The calculation bit code represents the calculation code input to the algorithm, i.e., the calculation bit code. The calculation code is the number input to the algorithm for calculation, the result code is the calculated value, the fill code is a random number, and the codes are separated by a preset separator.
[0037] When setting the smart card, the hidden code is also matched with the radio frequency signal according to the result calculated by the preset second algorithm.
[0038] In this application, the smart card reads radio frequency signals through a smart card reader connected to the controller. When the smart card reader reads the radio frequency signals, it transmits the radio frequency signals to the controller for the aforementioned processing.
[0039] Please refer to Figure 1 As shown, in step S102, the controller reads the radio frequency signal of the smart card, compares the radio frequency signal with the feature code, and determines the scope of permissions based on the comparison result;
[0040] After the controller obtains the radio frequency signal of the smart card, it first compares the radio frequency signal with the feature code. If the comparison result is a correct match, further verification is required.
[0041] The smart card reader has the function of reading the hidden code, including reading the hidden code through principles such as camera, ultraviolet light, and fluorescence.
[0042] After the hidden code is read, it is analyzed, including obtaining the algorithm code, calculation bit code, calculation code, filling code and result code through parsing.
[0043] The first step is to read the hidden code and then perform calculations based on the long string of numbers in the hidden code to obtain a calculated value. The calculation is based on a preset second algorithm, which can be one of various mathematical algorithms, and the calculated value is rounded up to the nearest decimal point.
[0044] The algorithm can also be a randomly generated addition, subtraction, multiplication, and division algorithm, which uniquely corresponds to each of the radio frequency signals.
[0045] The calculated value based on the second algorithm is compared with the pre-stored calculated value to obtain the verification result.
[0046] This application also requires a second calculation verification, which includes:
[0047] Read the algorithm code;
[0048] The preset algorithm is retrieved according to the algorithm code;
[0049] Retrieve the calculation bit code, and read the calculation code based on the calculation bit code;
[0050] The calculation code is input into the algorithm to obtain the calculation result;
[0051] The calculation result is compared with the result code to obtain the verification result.
[0052] Furthermore, the smart card reader can also reset the hidden code, which can be set randomly. After the setting is completed, the newly set hidden code is re-segmented and recalculated in the controller to obtain further security protection.
[0053] The hidden code is written sequentially on the smart card according to its position, therefore the smart card has a limited number of uses.
[0054] The steps for randomly generating the hidden code are as follows:
[0055] Generate a random number and use that random number as the algorithm code;
[0056] Two random numbers are generated as the bit codes for calculation. These two random numbers are different and do not exceed the preset maximum and minimum values.
[0057] Furthermore, if the first random number generated is less than the second, the calculated code is read in reverse order; otherwise, it is read in forward order.
[0058] A calculation code for generating random numbers is generated, the calculation code is input into the algorithm corresponding to the algorithm code to obtain a value, and the value is stored.
[0059] Fill code for generating random numbers.
[0060] The value calculated by the algorithm is used as the result code.
[0061] This application provides a random number generation step including:
[0062] A data circle is defined, consisting of multiple numbers connected end-to-end. An arc length is extracted based on this data circle, and this arc length includes several numbers from the data circle, such as... Figure 2 As shown.
[0063] Based on the selected number of the arc length, the following calculation is performed:
[0064]
[0065] Wherein, A represents a random number, D is a constant selected sequentially from (l, k), n is the number of numbers selected for the arc length, S is the value of the selected numbers for the arc length, i is the sequence number of the selected numbers for the arc length, which needs to start from the first number on the left or right side of the arc length, and n is selected sequentially from (j, h), that is, the number of numbers included in the arc length is variable.
[0066] When making a selection, the arc length rotates along the digital circle at a preset speed. During the rotation, the selection is made manually to stop the rotation and perform the above calculations.
[0067] The above verification confirms the authority of the temperature control personnel.
[0068] Please refer to Figure 1 As shown in step S103, if the scope of the permission includes temperature and humidity control, the temperature and humidity control program is invoked, the input control command is converted into a temperature and humidity device operation command, and then input into the temperature and humidity device.
[0069] Based on the above processing, the scope of permissions of the smart card is determined, which includes viewing, setting, and setting selection, and temperature and humidity control is performed based on the permissions.
[0070] Specifically, the temperature and humidity setting program is first retrieved according to the permissions, and then a control command is input. Under the control of the controller, the command is converted into a device operation command and input into the temperature and humidity device to control the operation of the device.
[0071] Preferably, the scope of permissions is represented by permission codes, which include control codes and scope codes. Control codes are used to limit control permissions, and scope codes are used to limit the scope of control.
