[0002] Currently, thermal power plants need to spend a large amount of money on coal procurement. For example, coal procurement accounts for about 80% of the power plant's capital expenditure. When thermal power plants inspect and accept purchased coal, they generally require the coal supplier to provide coal testing data.

[0044] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0045] Figure 1 This is a flow chart illustrating a control method for preventing the modification of coal quality test result data, provided by an embodiment of the present invention. This control method is applied to a coal quality test terminal and a test result receiving terminal, which provides an encryption interface for the coal quality test terminal. The encryption interface can be integrated into the host computer software of the coal quality test terminal (testing equipment) to facilitate communication with the test result receiving terminal (the fuel management information system at the thermal power plant, which receives and stores coal quality test result data).

[0046] A coal quality tester is a device or system used to test and analyze coal quality. It uses chemical and physical methods to test coal samples to determine quality indicators such as moisture, volatile matter, and calorific value. Specifically, a coal quality tester includes various analytical instruments and equipment, such as moisture detectors, volatile matter detectors, and calorific value detectors. These devices provide accurate coal quality data, helping users determine whether the coal meets standards. Using a coal quality tester typically requires users to log in to the system to ensure data security and operational accuracy. Through the tester, users can monitor and analyze coal quality in real time to ensure it meets production requirements.

[0047] See also Figure 1 The control method for preventing coal quality test result data from being modified may include the following steps 101 to 104.

[0048] 101. An encryption check bit field is added to the result measurement value database table for storing coal quality test result data through the coal quality test end.

[0049] In this step, a result measurement value database table can generally be pre-established in a database to store the coal quality test result data. The database type can be MySQL, Oracle, SQL Server, etc., and is not specifically limited here. Then, an encryption check digit field is added to the result measurement value database table.

[0050] 102. When the coal quality testing end obtains the coal quality testing result data, it calls the encryption interface to encrypt the coal quality testing result data to obtain the encrypted result data and the encrypted return result value; wherein, the encrypted return result value corresponds to the encryption check bit field.

[0051] In this step, for example, the original coal quality test result data is "123.45". After encrypting the coal quality test result data by calling the encryption algorithm of the test result receiving end through the encryption interface, the encrypted result data "aaa123" and the encrypted return result value "abc123" are obtained. "abc123" corresponds to the encryption check bit field. The encrypted result data itself has been protected by the encryption algorithm, which can reduce the possibility of modification. However, in order to further ensure the security of the data, the encrypted return result value can prevent man-in-the-middle attacks or other forms of tampering. This step can ensure that the test process and results are supervised and controllable, and can prevent the obtained coal quality test result data from being modified, thereby ensuring that the test result receiving end receives the true test data results.

[0052] 103. The encrypted result data and the encrypted return result value are added to the result measurement value database table after adding the encryption check bit field through the coal quality testing terminal.

[0053] In this step, for example, the encrypted result data "aaa123" obtained in the previous step can be stored in the result measurement value database table, and the encrypted return result value "abc123" can be stored in the encryption check bit field of the result measurement value database table.

[0054] 104. Obtain the encrypted result data and the encrypted return result value from the result measurement value database table through the test result receiving terminal, and decrypt and verify the encrypted result data based on the encrypted return result value.

[0055] In this step, the test result receiving terminal has access to the database. For example, a username and password can be pre-established for logging into the database. Using this username and password, the terminal establishes a connection with the database, thereby obtaining the encrypted result data and the encrypted return value from the result measurement database table. The encrypted result data is then decrypted and verified based on the encrypted return value to obtain the original coal quality test result data.

[0056] In this embodiment, an encryption check bit field is added to the result measurement value database table for storing coal quality test result data through the coal quality testing end; when the coal quality testing end obtains the coal quality test result data from the coal quality testing, the encryption interface is called to encrypt the coal quality test result data to obtain encrypted result data and encrypted return result value; the encrypted result data and encrypted return result value are added to the result measurement value database table after adding the encryption check bit field through the coal quality testing end; the encrypted result data and encrypted return result value are obtained from the result measurement value database table through the test result receiving end, and the encrypted result data is decrypted and checked based on the encrypted return result value, thereby reducing the possibility of the coal quality test result data being modified and ensuring that the test data obtained by the test result receiving end is the original data generated during the test process, so as to accurately accept the quality of the coal.

[0057] In one embodiment of the present specification, before the coal quality testing end tests the coal quality to obtain coal quality testing result data, the following steps may also be included:

[0058] The coal quality testing end's function of modifying the coal quality testing result data is shielded by the testing result receiving end.

[0059] In this embodiment, by shielding the coal quality testing end's modification function of the coal quality testing result data by the test result receiving end, the possibility of the coal quality testing result data being modified can be further prevented, ensuring that the test data obtained by the test result receiving end is the original data generated during the testing process, so as to accurately inspect the quality of the coal.

[0060] In one embodiment of the present specification, shielding the coal quality testing end from modifying the coal quality testing result data through the testing result receiving end may include:

[0061] The test result receiving terminal allocates read-only authority to the registered user of the coal quality testing terminal to shield the coal quality testing terminal from modifying the coal quality testing result data.

[0062] In this embodiment, when testing coal using the coal quality testing terminal, the tester must register as a user and then log in using the registered user before using the terminal to test the coal. The test result receiving terminal assigns read-only permissions to the registered user of the coal quality testing terminal, preventing the terminal from modifying the test result data. This method is simple and efficient.

[0063] In one embodiment of the present specification, shielding the coal quality testing end from modifying the coal quality testing result data through the testing result receiving end may include:

[0064] Detecting a function button having a modification function in the user interface of the coal quality testing terminal;

[0065] The program code corresponding to the function button is determined in the HTML code of the user interface, and the program code is shielded.

[0066] In this step, the program code corresponding to the function button is determined in the HTML code of the user interface and the program code is blocked. This prevents the test personnel from modifying the coal quality test result data by using the function button to modify the function at the coal quality test terminal, thus providing a high safety factor. Of course, this embodiment can also be combined with the read-only permission of the previous embodiment, and the two can be used together. That is, the program code corresponding to the function button is blocked, and read-only permission is also assigned to the registered user of the coal quality test terminal, thereby more comprehensively blocking the modification function of the coal quality test terminal and ensuring that the coal quality test result data obtained by the test result receiving terminal is authentic original data.

[0067] In one embodiment of the present specification, there are multiple encryption interfaces, each of which has a different encryption method. Calling the encryption interface to encrypt the coal quality test result data may include:

[0068] Determining each idle interface that has not been called in each of the encrypted interfaces;

[0069] At intervals of a preset time, an interface is called from each of the idle interfaces to encrypt the coal quality test result data.

[0070] In this embodiment, there are multiple encryption interfaces, each of which has a different encryption method. Unused idle interfaces are determined in each encryption interface, and one interface is called from each idle interface at a preset interval to encrypt the coal quality test result data. This encrypts the coal quality test result data using different encryption methods, reduces the possibility of the encryption method being cracked, further strengthens the confidentiality of the coal quality test result data, and reduces the possibility of the coal quality test result data being modified. Of course, multiple different encryption interfaces can also be called to encrypt the coal quality test result data, that is, the coal quality test result data can be encrypted using multiple encryption methods to improve the confidentiality of the coal quality test result data.

[0071] In one embodiment of the present specification, calling an interface from among the idle interfaces may include:

[0072] Randomly call an interface from the idle interfaces; or

[0073] Counting the number of times each of the idle interfaces is called;

[0074] Comparing the relationship between the number of times each idle interface is called;

[0075] Based on the size relationship, the interface with the smallest number of calls is called.

[0076] In this embodiment, the more frequently an encryption method is used, the greater the likelihood that it will be cracked. To avoid this and reduce the likelihood of the encryption method being cracked, the number of times each idle interface is called is counted, and the relative magnitude of the number of calls for each idle interface is compared. Based on this relative magnitude, the interface with the smallest number of calls is called. Alternatively, a random interface is called from each idle interface, allowing for irregular use of encryption interfaces, which also helps reduce the likelihood of the encryption method being cracked.

[0077] In one embodiment of the present specification, the step of adding the encrypted result data and the encrypted return result value to the result measurement value database table after adding the encryption check bit field through the coal quality testing terminal may further include:

[0078] monitoring whether an abnormal state occurs during the process of adding the encrypted result data and the encrypted return result value to the result measurement value database table after the encryption check bit field is added;

[0079] If so, identifying the abnormality type of the abnormal state;

[0080] Classify the abnormal state based on the abnormal type, and generate a log to record the abnormal state;

[0081] An exception analysis report is generated based on the exception type.

[0082] In this embodiment, abnormal conditions may generally include failure to connect to the database, data encryption failure, failure to write data into the result value database table, and failure to connect to the test result receiving terminal. Classifying the abnormal conditions based on the abnormality type facilitates faster resolution by relevant personnel based on the abnormality type. Generating a log to record the abnormal condition and generating an abnormality analysis report based on the abnormality type also facilitates faster resolution by relevant personnel based on the abnormality type.

[0083] In one embodiment of the present specification, before the coal quality testing end tests the coal quality to obtain coal quality testing result data, the following steps may also be included:

[0084] Obtain the coal sample information to be tested by scanning the code;

[0085] The code scanning method is the only way to obtain coal quality sample information.

[0086] In this embodiment, the coal sample information to be tested is obtained by scanning a code, and scanning is the only way to obtain coal sample information. This eliminates the need to manually enter coal sample information at the coal quality testing end, reducing the possibility of falsification of coal sample information. Coal sample information can include at least one of the following: basic information (such as coal sample number, sampling location, sampling time, and sampler); test items (such as moisture, ash, volatile matter, fixed carbon, sulfur, and calorific value); analytical method (such as the analytical method and standard used, such as industrial analysis or elemental analysis); sample state (such as a description of the sample's physical state, such as particle size, color, and odor); and other information (such as storage conditions and shipping records).

[0087] Figure 2 This is a schematic diagram of the structure of a control device for preventing the modification of coal quality test results, provided by an embodiment of the present invention. The control device is applied to a coal quality test terminal and a test result receiving terminal, with the test result receiving terminal providing an encryption interface for the coal quality test terminal. The control device includes a check digit addition module 201, an encryption module 202, a data storage module 203, and a data acquisition module 204.

[0088] The adding check bit module 201 is used to add an encrypted check bit field to the result measurement value database table for storing coal quality test result data through the coal quality test end;

[0089] The encryption module 202 is used to call the encryption interface to encrypt the coal quality test result data when the coal quality test end performs coal quality test on the coal quality test result data, thereby obtaining encrypted result data and an encrypted return result value; wherein the encrypted return result value corresponds to the encryption check bit field;

[0090] The data storage module 203 is used to add the encrypted result data and the encrypted return result value to the result measurement value database table after adding the encryption check bit field through the coal quality testing terminal;

[0091] The data acquisition module 204 is used to acquire the encrypted result data and the encrypted return result value from the result measurement value database table through the test result receiving terminal, and decrypt and verify the encrypted result data based on the encrypted return result value.
