[0029] Example 1

[0030] Figure 1 This is a flowchart illustrating a device alarm information generation method according to Embodiment 1 of the present invention. This embodiment of the invention is applicable to situations involving the generation of device alarm information. The method can be executed by a device alarm information generation device, which can be implemented in hardware and / or software and can be configured in an electronic device, such as a server.

[0031] See Figure 1 The method for generating device alarm information shown includes:

[0032] S101. Collect the candidate power value of the target device at at least one candidate travel position within the current time period.

[0033] In this embodiment, the target device can be a device whose degree of abnormality is to be determined. The candidate stroke position can be a position within the movement stroke of the target device. The candidate power value can be the power value of the target device's motor when the target device is at the candidate stroke position.

[0034] In one optional embodiment, the target device has at least one motion stroke within the current time period. The voltage and current values ​​of the target device's motor at at least one candidate stroke position in each motion stroke are collected; the power value of the motor at at least one candidate stroke position in each motion stroke is determined based on the voltage and current values; for each candidate stroke position, the average of the power values ​​at that candidate stroke position across all motion strokes is determined as the candidate power value of the target device at that candidate stroke position within the current time period. It should be noted that the candidate stroke positions and the length of the time period can be set independently by those skilled in the art based on actual needs or practical experience, and this invention does not limit them.

[0035] In an optional embodiment, when the target device is operating normally, candidate power values ​​are collected at at least one candidate travel position of the target device within the current time period.

[0036] S102. Determine the candidate anomaly level of the target device at the candidate travel position based on the candidate power value, the target power anomaly threshold and the anomaly level threshold at the candidate travel position; wherein, the target power anomaly threshold at the candidate travel position is determined based on the equipment failure rate of multiple candidate devices in the historical time period; the candidate devices and the target device have the same equipment type.

[0037] In this embodiment, the target power anomaly threshold can be a critical value for anomalies in candidate power values ​​at candidate travel positions. The anomaly severity threshold can be a critical value for target device anomalies. The candidate anomaly severity can be represented numerically, characterizing the anomaly of candidate power values ​​at candidate travel positions; where a smaller candidate anomaly severity value indicates a more anomalous candidate power value at candidate travel positions. The historical time period can be a time period prior to the current time period. For example, if a time period is a natural day, i.e., the length of the time period is 24 hours of the corresponding natural day, and the current time period is January 31, then the historical time period can be 30 time periods from January 1 to January 30. The device failure rate is the probability of a candidate device failing within the historical time period. The candidate device can be a device of the same type as the target device. In an optional embodiment, the target device and the candidate device perform the same motion stroke. The target device includes, but is not limited to, mechanical devices that perform reciprocating motion and mechanical devices that perform repetitive motion. Mechanical devices that perform reciprocating motion can be, for example, automatic doors and air conditioning compressors. Taking an automatic door as an example, a set of adjacent opening and closing movements constitutes one round trip motion. Mechanical devices that perform repetitive movements can be, for example, fans or rotating platforms. Taking a fan as an example, the fan blades rotate continuously during operation, and each rotation of the blades constitutes one round trip motion of the fan blades.

[0038] Specifically, for each candidate travel position, the power difference between the candidate power value at that candidate travel position and the target power anomaly threshold at that candidate travel position is determined; the power ratio between the power difference and the target power anomaly threshold at that candidate travel position is determined; the power ratio, the anomaly severity threshold, and the anomaly severity correction coefficient are determined to determine the candidate anomaly severity of the target device at that candidate travel position. For example, the candidate anomaly severity can be represented by the following formula:

[0039]

[0040] Among them, Y ip represents the degree of candidate anomaly at candidate route position i; i r represents the candidate power value at candidate stroke position i; i represents the target power anomaly threshold at candidate travel position i; h represents the anomaly degree threshold; k1 represents the anomaly degree correction coefficient.

[0041] S103. Determine the target anomaly level of the target device based on the candidate anomaly level at each candidate travel location.

[0042] In this embodiment, the target anomaly level can be represented numerically to characterize the overall anomaly level of the target device. The smaller the target anomaly level value, the more abnormal the target device. Specifically, the candidate anomaly level with the smallest value among the candidate anomaly levels at each candidate travel position is determined as the target anomaly level of the target device.

[0043] S104. Based on the degree of anomaly of the target, determine the target alarm information of the target device from multiple candidate alarm information.

[0044] In this embodiment, the target alarm information is the alarm information corresponding to the target anomaly level of the target device. Each candidate alarm information corresponds to a different anomaly level value. Based on the correlation between the candidate alarm information and the anomaly level value, and the target anomaly level, the target alarm information for the target device is determined from multiple candidate alarm information. For example, the candidate alarm information includes a first alarm information and a second alarm information, where the anomaly level value corresponding to the first alarm information is less than the anomaly level value corresponding to the second alarm information. If the target anomaly level value is less than or equal to the anomaly level value corresponding to the first alarm information, then the first alarm information is determined as the target alarm information. If the target anomaly level value is greater than the anomaly level value corresponding to the first alarm information and less than or equal to the anomaly level value corresponding to the second alarm information, then the second alarm information is determined as the target alarm information for the target device. If the target anomaly level value is greater than the anomaly level value corresponding to the second alarm information, then no target alarm information is generated for the target device.

[0045] In one optional embodiment, the anomaly threshold is a monthly inspection alarm threshold; candidate alarm information includes monthly inspection alarm information, and at least one of daily and weekly inspection alarm information. The monthly inspection alarm threshold is the critical value for determining monthly inspection alarm information. Monthly inspection alarm information can be used to indicate that the target equipment needs maintenance within one month; weekly inspection alarm information can be used to indicate that the target equipment needs maintenance within one week; and daily inspection alarm information can be used to indicate that the target equipment needs maintenance on the date corresponding to the current time period.

[0046] It is understandable that by adopting the above technical solution to determine the alarm information of the target equipment from the monthly, weekly, and daily inspection alarm information, the effectiveness of equipment maintenance work can be improved, the equipment failure rate can be reduced, and the stable operation of the target equipment can be guaranteed.

[0047] This invention, in its embodiments, collects candidate power values ​​for a target device at at least one candidate travel position within the current time period; determines the candidate anomaly level of the target device at each candidate travel position based on the candidate power values, a target power anomaly threshold, and an anomaly severity threshold; wherein the power anomaly threshold for each candidate travel position is determined based on the device failure rate of multiple candidate devices within a historical time period; the candidate devices and the target device are of the same device type; the target anomaly level of the target device is determined based on the candidate anomaly levels at each candidate travel position; and the target alarm information for the target device is determined from multiple candidate alarm information based on the target anomaly level. By employing the above technical solution, the efficiency of alarm information generation is improved, allowing for timely reminders to technicians to handle the target device based on the alarm information, enhancing the real-time performance of anomaly location and maintenance, and improving the stability of equipment operation.

[0048] Example 2

[0049] Figure 2 This is a flowchart illustrating the generation of device alarm information according to Embodiment 2 of the present invention. Based on the above embodiments, this embodiment adds an operation to determine the target power anomaly threshold at candidate travel positions.

[0050] Furthermore, the method for generating equipment alarm information is further improved by adding the following: "Based on the candidate power value of the candidate device at the candidate travel position in the current time period, the equipment failure rate of multiple candidate devices in the previous historical time period, and the average failure interval of the target device, determine the power anomaly threshold of the candidate travel position in the current time period; and determine the average value between the power anomaly threshold of the candidate travel position in multiple historical time periods and the power anomaly threshold of the candidate travel position in the current time period as the target power anomaly threshold of the candidate travel position."

[0051] It should be noted that for parts not described in detail in the embodiments of the present invention, please refer to the descriptions in other embodiments.

[0052] See Figure 2 The method for generating device alarm information shown includes:

[0053] S201. Collect the candidate power value of the target device at at least one candidate travel position within the current time period.

[0054] S202. Based on the candidate power value of the candidate device at the candidate travel position in the current time period, the equipment failure rate of multiple candidate devices in the previous historical time period of the current time period, and the average failure interval of the target device, determine the power anomaly threshold of the candidate travel position in the current time period.

[0055] In this embodiment, the mean time between failures (MTBF) of the target device can be a target value that the target device is required to meet during its production design. In an optional embodiment, the candidate device and the target device are of the same type and have the same MTBF. The previous historical time period of the current time period is the adjacent historical time period of the previous time period. For example, if a time period is one calendar day, and the current time period is January 31, then the previous historical time period of the current time period is January 30.

[0056] Optionally, based on the candidate power value of the candidate device at the candidate travel position in the current time period, the equipment failure rate of multiple candidate devices in the previous historical time period of the current time period, and the average fault interval of the target device, the power anomaly threshold of the candidate travel position in the current time period is determined, including: determining the maintenance ratio coefficient in the current time period based on the average fault interval of the target device and the equipment failure rate of multiple candidate devices in the previous historical time period of the current time period; sorting the candidate power values ​​of each candidate device in the current time period, and selecting the candidate power value at the position corresponding to the maintenance ratio coefficient as the power anomaly threshold of the candidate travel position in the current time period.

[0057] The maintenance ratio coefficient can be used to characterize the proportion of candidate equipment requiring maintenance to the total number of candidate equipment. A larger maintenance ratio coefficient indicates a larger number of equipment requiring maintenance, more ineffective maintenance of candidate equipment without abnormalities, and lower effectiveness of maintenance work on each candidate equipment. Conversely, a smaller maintenance ratio coefficient indicates a smaller number of equipment requiring maintenance, fewer ineffective maintenance of candidate equipment without abnormalities, and higher effectiveness of maintenance work on each candidate equipment. In one optional implementation, the maintenance ratio coefficient is expressed as a percentage. In a specific implementation, the candidate power values ​​of each candidate equipment in the current time period are sorted in descending order to determine the percentage order of each candidate power value in the sorting; the candidate power value closest to the percentage corresponding to the maintenance ratio coefficient is selected as the power anomaly threshold for the candidate travel position in the current time period.

[0058] It is understandable that by adopting the above technical solution, the maintenance ratio coefficient in the current time period is determined, and the power anomaly threshold of the candidate travel position in the current time period is determined by the maintenance ratio coefficient in the current time period. The power anomaly threshold can be adjusted according to the maintenance ratio coefficient, and the target anomaly degree of the target equipment can be adjusted by adjusting the power anomaly threshold. This avoids generating incorrect target alarm information for the target equipment when it is operating normally, which would cause the target equipment to need maintenance and increase the number of unnecessary maintenance equipment. It can effectively improve the accuracy of the target anomaly degree, the effectiveness of the target alarm information, and the effectiveness of the number of maintenance equipment determined based on the target alarm information.

[0059] In an optional embodiment, determining the maintenance ratio coefficient in the current time period based on the mean time between failures of the target device and the failure rates of multiple candidate devices in the previous historical time period of the current time period includes: determining the product between the mean time between failures of the target device and the failure rates of multiple candidate devices in the previous historical time period of the current time period; determining the ratio between the maintenance ratio correction coefficient and the product; and determining the sum of the ratio and the preset maintenance ratio as the maintenance ratio coefficient in the current time period.

[0060] The maintenance ratio correction factor can be a factor used to adjust the maintenance ratio coefficient. The preset maintenance ratio and the maintenance ratio correction factor can be set independently by technical personnel based on actual needs or practical experience. For example, the maintenance ratio coefficient can be expressed by the following formula:

[0061]

[0062] Where M represents the maintenance ratio coefficient; m represents the preset maintenance ratio; k2 represents the maintenance ratio correction coefficient; T represents the mean time between failures; and e represents the equipment failure rate.

[0063] It is understandable that by adopting the above technical solution, the accuracy of the maintenance ratio coefficient can be improved, thereby improving the accuracy of the power anomaly threshold of the candidate travel position in the current time period determined based on the maintenance ratio coefficient, and further improving the accuracy of the target power anomaly threshold of the candidate travel position.

[0064] The technical solution of this invention performs dynamic threshold self-learning by using the candidate power data of the target device and candidate devices of the same type. This avoids the high workload caused by acquiring and labeling fault samples in the prior art, improves the efficiency of alarm information generation, and enhances the applicability to mechanical transmission equipment.

[0065] S203. The average value between the power anomaly threshold corresponding to the candidate travel position in multiple historical time periods and the power anomaly threshold of the candidate travel position in the current time period is determined as the target power anomaly threshold of the candidate travel position.

[0066] S204. Determine the candidate anomaly level of the target device at the candidate travel position based on the candidate power value, the target power anomaly threshold, and the anomaly level threshold at the candidate travel position; wherein, the power anomaly threshold at the candidate travel position is determined based on the equipment failure rate of multiple candidate devices in a historical time period; the candidate devices and the target device have the same equipment type.

[0067] S205. Determine the target anomaly level of the target device based on the candidate anomaly level at each candidate travel location.

[0068] S206. Based on the degree of anomaly of the target, determine the target alarm information of the target device from multiple candidate alarm information.

[0069] This invention determines the power anomaly threshold of a candidate travel position in the current time period based on the candidate power value of a candidate device at a candidate travel position in the current time period, the device failure rate of multiple candidate devices in the previous historical time period, and the average fault interval of the target device. The average power anomaly threshold between the candidate travel position's corresponding power anomaly thresholds in multiple historical time periods and the candidate travel position's power anomaly threshold in the current time period is then determined as the target power anomaly threshold for the candidate travel position. By employing this technical solution, the accuracy of the target power anomaly threshold is improved, thereby enhancing the accuracy of determining the candidate anomaly degree at each candidate travel position based on the target power anomaly threshold.
