Description

Technical Field

[0001] The present invention relates to the technical field of power failure analysis, and in particular to a power failure analysis system and method based on a dual-mode communication module. Background Art

[0002] In modern society, electricity, as an indispensable energy source in human daily life, is widely used in many fields such as home, industry, and transportation. With the acceleration of electrification, the types and number of household appliances have increased rapidly, which has put forward higher requirements for power management and fault monitoring. In particular, the early warning and detection system of power faults is directly related to the safety and stability of electrical equipment and the rational use of electric energy.

[0003] Traditional power fault analysis methods mainly include: using electric meters to automatically monitor power consumption or through manual on-site detection. These methods have many limitations in monitoring the operating status of power equipment and fault judgment. Specifically, due to the lack of accurate monitoring of individual power equipment, it is difficult to know the operating status of each device in real time, especially the start and stop time of the equipment, so it is difficult to effectively warn of faults. In addition, traditional methods can often only detect serious equipment failures, but it is difficult to capture abnormal power consumption of equipment in a small range and within a short period of time, resulting in frequent omissions and false alarms.

[0004] In order to solve the above problems, the use of dual-mode communication modules can ensure that the collection and transmission of power data is more flexible and timely. In addition, by statistically analyzing the historical power consumption information of power-consuming equipment, a reasonable interval can be established for each device, and by real-time monitoring of the continuous use time of power-consuming equipment, abnormal conditions of power-consuming equipment can be discovered in time.

[0101] The present invention has the following beneficial effects:

[0102] 1. The power fault analysis system and method based on the dual-mode communication module obtains the power consumption information of all power-consuming devices in the set of electrical equipment in the current month. When the number of power consumption information of the power-consuming devices is less than or equal to the data volume threshold a, the power consumption information of the power-consuming devices in the previous month is obtained, until the number of power consumption information is greater than the data volume threshold a. In this way, a large amount of power consumption information can be collected as a basis for judgment, thereby improving the accuracy of the reasonable interval of each subsequent power-consuming device and reducing the judgment error; by comparing the interval time between adjacent power consumption information, two power consumption information with an interval time less than the time interval threshold b are merged; the reasonable interval of each power-consuming device is established respectively according to the power consumption information, and by merging the power consumption information with too small an interval time, it can be closer to the special circumstances that occur in the actual use of the power-consuming equipment, avoiding data errors caused by frequent startup of the power-consuming equipment.

[0103] 2. The power fault analysis system and method based on the dual-mode communication module sets a plurality of different high-frequency time periods to determine the time period in which the electrical equipment is turned on. The judgment and processing are performed according to the time period in which the electrical equipment is turned on and the actual continuous use time of the current electrical equipment and the corresponding reasonable interval. If the processing result does not conform to the corresponding reasonable interval, the continuous use time of the current electrical equipment is marked as abnormal data. This method can determine whether the continuous use time of the current electrical equipment is abnormal data according to the different time periods in which the continuous use time of different electrical equipment is located. This analysis method can improve the accuracy of fault detection, ensure that the continuous use time of different electrical equipment in different time periods can be kept within a reasonable range, and reduce errors.

[0104] 3. The power fault analysis system and method based on the dual-mode communication module judges the number of abnormal data each time the abnormal data is entered. When the number of abnormal data reaches a predetermined value, the reasonable range of the power equipment is adjusted according to the abnormal data. Through the continuous accumulation of abnormal data, the system can dynamically adjust the reasonable range of each power device, so that the reasonable range of each power device is more in line with the actual use of the power device, thereby enhancing the adaptive ability of the system. This function becomes more accurate as the use time of the power device increases, which helps to optimize the management of the power equipment.

[0105] 4. The power fault analysis system and method based on the dual-mode communication module further refines the judgment criteria for equipment usage by setting time adjustment thresholds and high-frequency time periods, avoiding misjudgments caused by short-term fluctuations or changes in electricity consumption during non-peak hours, and improving the accuracy of fault analysis.

[0106] 5. The power fault analysis system and method based on the dual-mode communication module periodically monitors and processes data of all electrical equipment in the electrical equipment collection through the system to ensure that the usage status and reasonable range of each device can be accurately updated. This dynamic management mechanism improves the response speed and intelligence level of the overall system. BRIEF DESCRIPTION OF THE DRAWINGS
