[0027] Embodiment 3: The specific methods for real-time monitoring of data transmission links and ensuring the security of the transmission link status are as follows: Step 1: Continuously obtain the status data of the transmission link between the test host and the test board. The status data includes traffic changes, abnormal SPI rates, and unusual data delays. Step 2: Compare the status data with the preset threshold range. When the status data is outside the preset threshold range, the transmission link status is abnormal, and the security protocol is immediately triggered to disconnect the transmission link and generate an alarm message to warn the test host through a secure channel. Step three: when the status data is within the preset threshold range, the transmission link status is safe, the transmission link is restored, and the data is resent to ensure the integrity of the data.

[0028] Embodiment 4: The specific method of obtaining the historical data and real-time data of the power load through the state-secure transmission link and encrypting the historical data and real-time data is as follows: Step 1: Obtain historical and real-time data of power load through a state-secure transmission link, and use hash algorithm and timing verification method to ensure data integrity and avoid duplication.

[0029] Step 2: Use a hash algorithm (such as SHA-256) to generate a unique hash value for each data packet in the historical data and real-time data. The hash value includes the serial number and timestamp of each data packet.

[0030] Embodiment 5: The specific method for decrypting the encrypted historical data and real-time data of power load is as follows: Step 1: The test host calculates the hash value of each data packet in the historical data and the real-time data according to the encrypted historical data and the real-time data of the power load; Step 2: Compare the calculated hash value with the encrypted hash value. If the comparison results are consistent, the encrypted historical data and real-time data of the power load are decrypted using the calculated hash value to ensure that the data has not been tampered with during transmission.

[0031] Embodiment 6: The specific method for verifying the decrypted historical data and real-time data of the power load, eliminating obviously erroneous data and / or damaged data, and obtaining data with complete data and correct format is as follows: Step 1: Obtain the serial number and timestamp of each data packet in the decrypted historical data and real-time data of the power load.

[0032] Step 2: determine whether the sequence numbers of adjacent data packets are continuous. If the sequence numbers are not continuous, the historical data and real-time data are obviously erroneous data and / or damaged data; otherwise, the data is complete and in the correct format.

[0033] It is determined whether the timestamps of all data packets are within the required time. Data packets corresponding to timestamps outside the required time are obviously erroneous data and / or damaged data, while the others are complete and correctly formatted data.

[0034] Embodiment 7: The specific method of transmitting the required preset test templates and encrypted historical data and real-time data through a state-secure transmission link is as follows: Step 1: During the remote testing process, the cloud sends test data to the test host in real time according to resource allocation. The test host obtains the required preset test templates and encrypted historical data and real-time data, and stores all the obtained data in the data cache area.

[0035] Step 2: Monitor the usage rate of the data cache area in real time and strictly limit the test host in the cache area to monitor the usage rate of the data cache area in real time and keep the proportion of unused data between 5% and 10%. This proportion range is set as the normal operating range of the cache area.

[0036] Step 3: When the unused data in the data buffer exceeds the upper limit of 10%, the test host will automatically stop receiving new data and disconnect the transmission link to prevent overload; When the unused data in the data cache area drops to the lower limit of 5%, the transmission link is restarted and the test host should automatically send a data request to the cloud to increase the priority of data transmission to ensure that the test is not interrupted due to insufficient data.

[0037] Embodiment 8: See also Figure 3 This embodiment adopts a layered architecture design, and the test function is jointly implemented by "cloud + local", meeting the requirements of scalability, easy maintainability, high security and confidentiality, and high stability.

[0038] This embodiment includes a front end (user interaction interface), a back end (server, database), security measures (verification, data encryption, etc.), a test host and a test board (equipped with a test program).

[0039] The front end provides users with an intuitive operation interface. It supports specifying data tests and viewing test results. The interface includes file upload functions, execution parameter settings (if applicable), execution status display, and result display; it collects and displays test results after the algorithm is executed. It includes data output, performance indicator display (such as execution time, memory usage, etc.) and abnormal information pop-up.

[0040] The backend has the following functions: Data management and testing: Support users to specify or upload data sets for testing algorithms. The system can process the data, pass it to the user's algorithm, and collect the output of the algorithm.

[0041] Logging and monitoring: Build a logging and monitoring system to record user upload behavior, algorithm execution process, system performance and other information to support subsequent debugging and optimization of the system.

[0042] Safety measures include the following features: When the cloud database sends test data to the test board, the encryption algorithm is used to encrypt the data, and the test board decrypts the load data and inputs it into the program under test to complete the subsequent test process; The test board adopts black box packaging. Except for the program burning port, it does not support the storage of test waveform data through other data interfaces to prevent the leakage of test data. The test host sets up a data buffer area to perform data verification, sorting, and upload and download control; When the cloud database sends test data to the test board, frame checking will be used. The cloud database will output the transmission frame length bits based on the length of each frame of data (the length of each frame needs to be customized according to the transmission speed) by using the secure hash-256 algorithm. After the test board receives the spi data, it will use the same algorithm to calculate the length bits based on the received message length. If the length bits are consistent, the load data will be input into the identification algorithm. If they are inconsistent, an error message will be output to the cloud database. The cloud database will resend the data based on the error message to ensure data integrity.

[0043] To prevent file tampering and loss, a timing algorithm check is performed on each frame to ensure that the received data packet is the latest and to prevent replay attacks. Each data packet includes a unique serial number and timestamp. An increasing serial number is attached to each data packet when it is sent. The test motherboard checks whether the received serial number is greater than the last received serial number. The calculation method is as follows:

[0044] in, is the received sequence number, Is the last received sequence number.

[0045] The data file package is accompanied by a timestamp. The receiving end checks whether the difference between the timestamp and the current time is within the allowed range. The calculation method is as follows:

[0046] in, is the current time, is the timestamp of the packet, The maximum allowed time difference.

[0047] The functions of the test host include program compilation, process control, and hardware monitoring.

[0048] Strict access control is implemented when users use the test host, and only authorized system IPs and personnel are allowed to access the data cache. After the user logs in, the test plan will be compiled through the test host to achieve the ability to execute test instructions; Based on the time, test data, and current test tasks that the test host applies to the cloud for test requests, the cloud sets the availability and test priority of the remote test board through the test host, and dynamically adjusts resource allocation and test plans to ensure that there is sufficient monitoring resource coverage during critical periods. Once the test board determines the test, the test host automatically executes and monitors the execution status in real time, and conducts real-time control over human intervention or terminal modification during the test process.

[0049] The test board supports users to select test boards with different resource levels according to the main frequency and storage resources required by their own identification algorithms. The test board uses a LAN port to achieve data interaction and has a dedicated program burning interface to support users to upload identification algorithms to be tested.

[0050] Embodiment 9: The test process of this embodiment is as follows: Step 1: The cloud server of this system collects historical data and real-time data about power load, including but not limited to time, load, seasonal changes, user behavior patterns, etc.

[0051] Step 2: The user obtains the test board according to the resource parameters such as main frequency and memory required by its own program. When remote testing is required, the program is burned into the test board through the program burning interface.

[0052] Step 3: The user uses the client to select the required test waveform, connects the test host and the test board via a network cable, configures the test plan and starts the test.

[0053] Step 4: Based on the time, test data and current test tasks requested by the test host, the cloud system will dynamically adjust resource allocation and test plans according to the availability and test priority of the server settings to ensure sufficient monitoring resource coverage during critical periods.

[0054] Step 5: Once the test remote plan is determined, the system automatically executes it and monitors the execution status in real time, making real-time adjustments to the human intervention of the terminal during the test or the operation of the test host and test board.

[0055] Step 6, data verification: During the remote test, the cloud sends test data to the test host in real time according to the resource allocation. The test host puts the test data into the data cache area and monitors the data transmission and reception of the data cache area in real time, strictly limiting the cache area. The test host will monitor the usage rate of the data cache area in real time, and keep the proportion of unused data between 5% and 10%. This proportion range is set as the normal operating range of the cache area. When the amount of unused data in the cache area exceeds the upper limit of 10%, the test host will automatically stop receiving new data to prevent overload; if the amount of unused data drops to the lower limit of 5%, the test host should automatically send a data request to the cloud to increase the priority of data transmission to ensure that the test is not interrupted due to insufficient data.

[0056] The performance monitoring tool configured in the test host monitors the status of the data cache in real time and automatically reports any situation that exceeds the predetermined threshold. This helps to adjust resource allocation strategies in a timely manner and prevent potential system bottlenecks. At the same time, when the data is not fully transmitted, the test case data is missing and the cloud does not feedback the test results of the device.

[0057] At the same time, the local end needs to receive the test data for verification, check the integrity and format correctness of the data, and eliminate obvious errors or data corruption problems.

[0058] 1) This solution uses hash algorithm and timing verification method to ensure data integrity and avoid duplication; 2) The hash algorithm (such as SHA-256) generates a unique hash value for each data packet sent. After the test host receives the data, it recalculates the hash value of the data packet and compares it with the received hash value to ensure that the data has not been tampered with during transmission; 3) Each data packet contains a unique sequence number and timestamp. This not only helps the terminal identify and arrange the received data packets, but also prevents replay attacks and ensures the timeliness and order of data.

[0059] When the test host and test board need to have a safety mechanism after being disturbed by the outside world, implement network monitoring tools according to the real-time monitoring and response system to continuously monitor data transmission anomalies (such as traffic changes, spi rate anomalies, unusual data delays, etc.). Once an anomaly is detected, the safety protocol is immediately triggered to terminate data transmission and warn the test host through a secure channel. After detecting interference, when it is necessary to roll back to a safe state, recovery is performed to ensure data integrity.

[0060] Internal closed-loop data protection: To prevent data loss during the test process, the cloud needs to verify the legitimacy of the test host through a dongle authentication, and at the same time verify the legitimacy of the test board through the test host to ensure that the test data flow during the test is all within the system and will not be leaked.

[0061] The test board needs to be sealed or anti-counterfeit stickers installed at key locations to prevent human opening. The cloud management party needs to regularly check or verify the integrity of the test board before testing to prevent human opening.

[0062] Step 7, test result determination: The cloud reads the program identification result through the standard protocol interface, calculates the identification result score based on the judgment algorithm in the cloud, and generates a test conclusion.

[0063] Step 8: Complete the test.
