A reference data transmission response time length obtaining module, configured to, when the data transmission response time length exceeds a preset first response time length threshold, but does not exceed a preset second response time length threshold, call a data transmission response time length corresponding to a last data transmission when the current data transmission response time length exceeds the preset first response time length threshold, as a reference data transmission response time length;
The first data transmission response coefficient acquisition module is used for acquiring a first data transmission response coefficient by combining the data transmission response time length corresponding to each leakage data transmission of the power blocking module with the reference data transmission response time length, wherein the first data transmission response coefficient is acquired through the following formula:
wherein F x represents a first data transmission response coefficient, F max represents a data transmission response time length corresponding to a first preset response time length threshold value but not a second preset response time length threshold value, F 01 and F 02 respectively represent a first response time length threshold value and a second response time length threshold value, F 01 represents a first adjustment coefficient, and the first adjustment coefficient is obtained by the following formula:

and the first abnormality judgment module is used for judging that the power blocking module has abnormal data transmission response when the first data transmission response coefficient does not exceed a preset first coefficient threshold value, and carrying out abnormality alarm.
The technical effect of the technical scheme is that the system can track the time point of acquiring the electric leakage data (data acquisition time) and transmitting the data to the control module (data transmission time) in real time through the first real-time monitoring module and the second real-time monitoring module. The real-time monitoring mechanism is helpful for timely finding and processing potential problems in the data transmission process, and the response speed and the fault detection capability of the system are improved.
The data transmission response time length acquisition module can accurately calculate the time difference from data acquisition to transmission, namely the data transmission response time length. This provides an important basis for the subsequent analysis of the state of the power block or data transmission link.
The reference data transmission response time length acquisition module and the first data transmission response coefficient acquisition module work together to construct a dynamic evaluation system. When the data transmission response time exceeds a certain threshold but is still within an acceptable range, the system invokes the historical data (reference data transmission response time) to evaluate the current state. This mechanism allows the system to more flexibly and accurately determine the performance change of the resistive module rather than relying on a single fixed threshold.
By introducing the first data transmission response coefficient and the calculation formula thereof, the system can intelligently evaluate the performance of the power blocking module in the data transmission process. When the first data transmission response coefficient is lower than a preset threshold value, the system can automatically judge that the data transmission response abnormality exists in the power-blocking module and trigger an abnormality alarm. The intelligent evaluation and early warning mechanism greatly improves the reliability and maintenance efficiency of the system.
By detailed analysis and evaluation of the data transmission response time, the system can more accurately locate the problem sources such as the power blocking module itself, the data transmission link or the control module, etc., which cause delay or failure of data transmission. This provides a powerful support for subsequent troubleshooting and repair work.
In summary, the technical scheme effectively improves the reliability of the data transmission of the power blocking module and the overall performance of the system through means of real-time monitoring, dynamic adjustment, intelligent evaluation, accurate positioning and the like, and provides powerful guarantee for electric power safety monitoring and fault early warning.
Specifically, the control module further includes:
the data transmission response time length calling module is used for calling the data transmission response time length corresponding to each leakage data transmission of the power blocking module when the data transmission response time length exceeds a preset second response time length threshold value
The second data transmission response coefficient acquisition module is used for acquiring a second data transmission response coefficient by utilizing the data transmission response time length corresponding to each leakage data transmission of the power blocking module, wherein the second data transmission response coefficient is acquired through the following formula:
Wherein F y represents a second data transmission response coefficient, F maxy represents a data transmission response time corresponding to a second preset response time threshold, F 02 represents a second response time threshold, and F 02 represents a second adjustment coefficient, and the second adjustment coefficient is obtained by the following formula:
Wherein F 02 represents a second adjustment coefficient, n represents the total times corresponding to the leakage data transmission of the power blocking module, F i represents the data transmission response time corresponding to the ith leakage data transmission, F 01 and F 02 respectively represent a first response time threshold and a second response time threshold, and F maxy represents the data transmission response time corresponding to the second response time threshold exceeding the preset value;
and the second abnormality judgment module is used for judging that the data transmission response abnormality exists in the power blocking module and carrying out abnormality alarm when the second data transmission response coefficient exceeds a preset second coefficient threshold value.
The technical effect of the technical scheme is that by introducing the data transmission response time length calling module and the second data transmission response coefficient obtaining module, when the data transmission response time length exceeds a preset second response time length threshold (the threshold is usually higher than the first response time length threshold and represents more serious delay or potential problem), the system can comprehensively call the response time length of each leakage data transmission of the power blocking module and conduct deep analysis. This depth detection mechanism helps to find data transmission problems that occur infrequently but have significant impact, improving the fault detection capabilities of the system.
The calculation of the second data transmission response coefficient considers the response time of the power blocking module for multiple data transmission, and introduces a second adjustment coefficient to dynamically adjust the evaluation result. This design enables the system to more accurately reflect the trend of performance changes of the power blocking module over long periods of operation, particularly when faced with extreme or abnormal conditions.
The second abnormality determination module performs accurate abnormality determination based on a comparison result of the second data transmission response coefficient and a preset second coefficient threshold. When the second data transmission response coefficient exceeds the threshold value, the system can immediately judge that the data transmission response abnormality exists in the power blocking module and trigger an abnormality alarm. This mechanism ensures that the system can quickly respond to and handle serious data transmission problems, avoiding potential safety hazards.
Through a series of measures such as real-time monitoring, depth detection, dynamic evaluation and accurate judgment, the technical scheme is beneficial to optimizing the overall stability of the system. The system can not only discover and process problems in the data transmission process in time, but also predict and prevent potential faults through historical data analysis and performance evaluation, so that the reliability and maintenance efficiency of the system are improved.
For a system which relies on the power blocking module to perform power safety monitoring and fault early warning, the technical scheme can remarkably improve user experience. By reducing the data transmission delay and the failure rate, the system can more accurately reflect the running state of the power equipment, provide more reliable and timely failure early warning information for the user, and enhance the safety and the trust of the user.
In summary, according to the technical scheme, through measures such as deep fault detection, dynamic evaluation and adjustment, accurate abnormality judgment and the like, the stability of data transmission of the power blocking module and the overall performance of the system are effectively improved, and more reliable technical support is provided for electric power safety monitoring and fault early warning.
