Description

Technical Field

[0001] The present invention relates to the technical field of distribution management, and in particular to a power distributor management method and system. Background Art

[0002] In the context of increasingly extensive and complex application scenarios of electronic equipment today, the importance of managing power distributors as key equipment for power distribution is self-evident.

[0003] However, the power distributor management method in the prior art still has the following deficiencies:

[0004] It is impossible to monitor the load of each output circuit in real time and accurately. When the load is too high, it is impossible to optimize and adjust the load in time, which will lead to circuit overload, equipment damage, fire and other safety hazards.

[0005] Moreover, when the circuit load does not reach the excessively high threshold, it is not possible to analyze the changing trend of the circuit load within the set time period to assess whether there is a potential risk. There is a lack of an effective early warning mechanism to prevent problems from occurring in advance and to manage them in advance.

[0006] In addition, when an abnormal situation occurs in the power distributor, such as electrical connection failure, component damage failure or overheating, how to quickly and accurately select appropriate maintenance personnel to handle it is also a key issue; most existing technologies arrange maintenance personnel by random allocation, resulting in low processing efficiency and increased economic losses.

[0007] To this end, a power distributor management method and system are introduced. Summary of the invention

[0008] In view of this, the present invention provides a power distributor management method and system to solve the problems raised by the above background technology.

[0009] The object of the present invention can be achieved by the following technical solution: A power distributor management method, comprising:

[0010] Power distribution: Perform power detection and regional classification on the equipment that needs power supply, calculate the total power demand of the equipment in each area, and distribute the input power according to the total power demand;

[0011] Load evaluation: Based on a preset time period, the load conditions of each output circuit of the power distributor corresponding to the preset time period are monitored in real time and analyzed. Based on the analysis results, the load optimization signaling within the current preset time period is triggered and corresponding steps are executed to adjust the power distributor;

[0012] Hazard analysis: When each output circuit does not trigger the load optimization signaling, the power of each output circuit corresponding to each division point within the preset time period is extracted according to the set division point, and the early warning risk model of each output circuit is constructed, and the corresponding steps are executed based on the early warning risk model of each output circuit;

[0013] Exception handling: When an abnormal situation occurs, the maintenance signaling is directly triggered and the maintenance capability value of each maintenance personnel who is in working state at the current time point is analyzed. Based on the maintenance capability value of each maintenance personnel, the corresponding maintenance personnel are selected to go to the location of the power distributor for processing.

[0014] In some embodiments, the load conditions of each output circuit of the power distributor corresponding to the power distributor within a preset time period are monitored in real time and analyzed, specifically:

[0015] M1: According to the set division points, extract the current value and voltage value of the output circuit of each division point within the preset time period, multiply the current value and voltage value of each division point respectively to obtain the power of each division point, calculate the average of the power of each division point, and thus obtain the average power of each output circuit within the preset time period; obtain the rated power corresponding to each output circuit, calculate the ratio of the power average to the corresponding rated power and record it as the load ratio, that is, power average / rated current; preset a reference threshold value for the load ratio of each output circuit. If the load ratio of a certain output circuit within the preset time period is higher than the corresponding preset reference threshold value, it is determined that the load is too high and triggers the load optimization signaling.

[0016] In some embodiments, corresponding steps are performed to adjust the power distributor, specifically:

[0017] M2: When triggering the load optimization signaling, first extract the load ratio and reference threshold of the output circuit corresponding to the trigger load optimization signaling, and calculate the difference to obtain the load difference, preset three groups of reference ranges corresponding to the load difference, set the three groups of reference ranges to correspond to the light load level, the moderate load level and the severe load level respectively, match the load difference of the corresponding output circuit with the corresponding reference range, so as to obtain the load level corresponding to the corresponding output circuit, if the load level is the light load level, execute step M2-201; if the load level is the moderate load level, execute step M2-202; if the load level is the severe load level, execute step M2-203;

[0018] M2-201: Obtain the load transfer range corresponding to the light load level, extract the idle capacity of each output circuit within the load transfer range, select the output circuit with the largest idle capacity as the transfer circuit, and gradually transfer according to the set power amount of the single transfer corresponding to the light load level. During the transfer process, gradually transfer according to the priority set for each device in the area corresponding to the output circuit until the load ratio is lower than the corresponding preset reference threshold;

[0019] M2-202: Based on step M2-201, the load transfer range and the set power amount of a single transfer corresponding to the medium load level are replaced as an execution step of the medium load level;

[0020] M2-203: Based on step M2-201, the load transfer range and the set power amount for a single transfer corresponding to the severe load level are replaced as the execution step of the severe load level. At the same time, a hidden danger signal is triggered and sent to the technician. The technician receives the triggered hidden danger signal and searches for the area corresponding to the output circuit.

[0021] In some embodiments, performing corresponding steps to adjust the power distributor further includes:

[0022] M3: If the number of output circuits triggering the load optimization signaling is greater than one, the output circuits are arranged according to their preset priorities, and then step M2 is executed in the order of arrangement.

[0023] In some embodiments, a warning risk model for each output circuit is constructed, specifically:

[0024] S1: Calculate the power of each output circuit corresponding to each division point using the standard deviation formula to obtain the fluctuation value of each output circuit in a preset time period and the reference value corresponding to the preset fluctuation value. If the fluctuation value of one group of output circuits is higher than the preset reference value, it is marked as a warning output circuit, otherwise it is marked as a normal output circuit.

[0025] S2: extract the power of each division point corresponding to the early warning output circuit, and arrange them in the time sequence of each division point. After the arrangement is completed, calculate the difference between two adjacent groups of power from left to right, and subtract the value on the left from the value on the right of the two adjacent groups of power; if the difference between two adjacent groups of power is a negative value, mark the negative value as a decreasing value, and if the difference between two adjacent groups of power is a positive value, mark the positive value as an increasing value; take the absolute value of all decreasing values ​​and sum them to obtain the total decreasing value; sum all increasing values ​​to obtain the total increasing value; calculate the ratio between the total increasing value and the total decreasing value, that is, the total increasing value / the total decreasing value, to obtain the power change ratio;

[0026] S3: taking the maximum power value from the powers of each division point corresponding to the early warning output circuit, and obtaining the rated power corresponding to the early warning output circuit, and calculating the ratio of the maximum power value to the rated power, that is, obtaining the power early warning ratio by dividing the maximum power value by the rated power;

[0027] S4: Using the power change ratio and the power warning ratio as the length value and the width value of the rectangle respectively, and constructing a rectangle, and using the constructed rectangle as a warning risk model of the warning output circuit within a preset time period.

[0028] In some embodiments, corresponding steps are performed based on the early warning risk model of each output circuit, specifically:

[0029] S5: Calculate the area value of the early warning output circuit corresponding to the early warning risk model, and compare the calculated area value with the preset area threshold. If the area value of the early warning output circuit corresponding to the early warning risk model is higher than the preset area threshold, trigger the early warning optimization signaling;

[0030] S6: When the early warning optimization signaling is triggered, the maximum power value of the corresponding output circuit is multiplied by the set transfer ratio according to the transfer ratio set corresponding to the early warning optimization signaling, and is used as the amount of power that the output circuit needs to transfer in advance. The triggered early warning optimization signaling is converted to a light load level, and step M2-201 is executed.

[0031] In some embodiments, the maintenance signaling is directly triggered and the maintenance capability value of each maintenance personnel in working state at the current time point is analyzed, specifically:

[0032] The total number of maintenance times of each candidate is extracted from the work log of each candidate, the value ranges of each group of times corresponding to the total number of maintenance are preset, and each group of number value ranges is set to correspond to an experience index; the total number of maintenance times of each candidate is matched with the preset value ranges of each group of times, so as to obtain the experience index of each candidate.

[0033] In some embodiments, directly triggering the maintenance signaling and analyzing the maintenance capability value of each maintenance personnel in working state at the current time point also includes:

[0034] Obtain the duration of each maintenance for each candidate. The duration starts from the time when each candidate is selected and ends when the processing is completed.

[0035] The reference duration range corresponding to the preset duration is as follows: if the duration used by the candidate for selection is within the preset reference duration range, the duration used by the candidate for selection for that time is marked as normal processing duration; if the duration used by the candidate for selection for that time is higher than the preset reference duration range, the duration used by the candidate for selection for that time is marked as delayed processing duration; if the duration used by the candidate for selection for that time is lower than the preset reference duration range, the duration used by the candidate for selection for that time is marked as early processing duration;

[0036] Count the number of advance processing time, normal processing time and delayed processing time for each candidate respectively, record them as advance number Q1, normal number Q2 and delayed number Q3, mark the total number of each candidate as Q4, according to the formula The number of advance times Q1, the number of normal times Q2 and the number of delayed times Q3 of each candidate are weighted and calculated to obtain the processing performance value QER of each candidate; wherein a1, a2 and a3 are the influencing weight factors of the number of advance times Q1, the number of normal times Q2 and the number of delayed times Q3 respectively;

[0037] The processing performance value QER of each candidate is multiplied by the experience index to obtain the maintenance capability value of each candidate; the candidate with the largest maintenance capability value is selected as the maintenance personnel who triggers the maintenance signaling this time, and the location of the power distributor is sent to the maintenance personnel.

[0038] In some embodiments, a power distributor management system includes:

[0039] The allocation module is used to detect the power of the power supply equipment and classify the area, calculate the total power demand of the equipment in each area, and allocate the input power according to the total power demand;

[0040] The evaluation module is used to monitor and analyze the load conditions of each output circuit of the power distributor in real time according to the preset time period, trigger the load optimization signaling in the current preset time period based on the analysis results and execute corresponding steps to adjust the power distributor;

[0041] The analysis module is used for extracting the power of each output circuit corresponding to each division point within a preset time period according to the set division point if each output circuit does not trigger the load optimization signaling, and constructing a warning risk model for each output circuit, and executing corresponding steps based on the warning risk model of each output circuit;

[0042] The processing module is used to directly trigger maintenance signaling and analyze the maintenance capability values ​​of each maintenance personnel who is in working state at the current time point when an abnormal situation occurs. Based on the maintenance capability value of each maintenance personnel, the corresponding maintenance personnel are selected to go to the location of the power distributor for processing.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] The present invention installs a current sensor and a voltage sensor on each output circuit of the power distributor, monitors the load condition of each output circuit in a preset time period in real time based on a preset time period, and when the load is too high and triggers the load optimization signaling, it is divided into light, moderate and severe load levels according to the load difference, and different load transfer strategies are adopted for different levels, thereby solving the problem that the load condition of each output circuit cannot be monitored in real time and accurately in the prior art, and when the load is too high, effective load optimization and adjustment cannot be carried out in time, resulting in circuit overload;

[0045] The present invention extracts and analyzes the power according to the set division points when each output circuit does not trigger the load optimization signaling, obtains the power change ratio and the power warning ratio, and constructs a rectangle as a warning risk model, calculates its area value and compares it with the preset threshold value, and triggers the warning optimization signaling if it is higher than the threshold value, and performs early power transfer according to the strategy of the light load level to relieve the circuit pressure;

[0046] The present invention directly triggers maintenance signaling and analyzes the maintenance capability values ​​of each maintenance personnel who is in working state at the current time point when an abnormal situation occurs. The total number of maintenance times is extracted from the work log to match the experience index, and the processing performance value is obtained by counting the time taken for each maintenance. The two are multiplied to obtain the maintenance capability value, and the candidate with the largest maintenance capability value is selected as the maintenance personnel who triggers the maintenance signaling this time, and the location of the power distributor is sent to the maintenance personnel, ensuring that the abnormal situation can be handled efficiently and accurately.

[0052] See also Figure 1 As shown, a power distributor management method includes:

[0053] Power distribution: Perform power detection and regional classification on the devices that need power supply, calculate the total power demand of the devices in each area, and distribute the input power according to the total power demand:

[0054] Power detection can be done by installing a power sensor on the device or obtaining power information from the device's technical specifications; and adjusting the power supply of the output port;

[0055] Load evaluation: Install current sensors and voltage sensors on each output circuit of the power distributor. Based on a preset time period, monitor and analyze the load conditions of each output circuit of the power distributor in real time. Based on the analysis results, trigger the load optimization signaling within the current preset time period and execute corresponding steps to adjust the power distributor.

[0056] Specifically:

[0057] M1: According to the set division points, extract the current value and voltage value of the output circuit of each division point within the preset time period, multiply the current value and voltage value of each division point respectively to obtain the power of each division point, calculate the average of the power of each division point, and thus obtain the average power of each output circuit within the preset time period; obtain the rated power corresponding to each output circuit, calculate the ratio of the power average to the corresponding rated power and record it as the load ratio, that is, power average / rated current; preset a reference threshold value for the load ratio corresponding to each output circuit, if the load ratio of a certain output circuit within the preset time period is higher than the corresponding preset reference threshold value, it is determined that the load is too high and triggers the load optimization signaling;

[0058] M2: When triggering the load optimization signaling, first extract the load ratio and reference threshold of the output circuit corresponding to the trigger load optimization signaling, and calculate the difference to obtain the load difference, preset three groups of reference ranges corresponding to the load difference, set the three groups of reference ranges to correspond to the light load level, the moderate load level and the severe load level respectively, match the load difference of the corresponding output circuit with the corresponding reference range, so as to obtain the load level corresponding to the corresponding output circuit, if the load level is the light load level, execute step M2-201; if the load level is the moderate load level, execute step M2-202; if the load level is the severe load level, execute step M2-203;

[0059] M2-201: Obtain the load transfer range corresponding to the light load level, extract the idle capacity of each output circuit within the load transfer range, select the output circuit with the largest idle capacity as the transfer circuit, and gradually transfer according to the set power amount of the single transfer corresponding to the light load level. During the transfer process, gradually transfer according to the priority set for each device in the area corresponding to the output circuit until the load ratio is lower than the corresponding preset reference threshold;

[0060] The operation is carried out in units of 5%-10% of the equipment load of the rated power each time, and is achieved by gradually adjusting the conduction state of the intelligent switch or relay in the power distributor to avoid instantaneous voltage fluctuations or power outages on the equipment;

[0061] For light load levels, the nearest output circuit with relatively large idle capacity is preferred for small load transfer.

[0062] M2-202: Based on step M2-201, the load transfer range and the set power amount of a single transfer corresponding to the medium load level are replaced as an execution step of the medium load level;

[0063] M2-203: Based on step M2-201, the load transfer range and the set power amount of a single transfer corresponding to the severe load level are replaced as the execution step of the severe load level, and a hidden danger signaling is triggered and sent to the technician. The technician receives the triggered hidden danger signaling and searches the area corresponding to the output circuit;

[0064] It should be noted that the load transfer range of the severe load level > the load transfer range of the moderate load level > the load transfer range of the slight load level;

[0065] The set power amount for a single transfer at a severe load level is > the set power amount for a single transfer at a moderate load level is > the set power amount for a single transfer at a slight load level.

[0066] M3: If the number of output circuits triggering the load optimization signaling is greater than one, after arranging the output circuits according to the preset priorities, step M2 is executed in the order of arrangement;

[0067] It should be noted that if a certain output circuit triggers load optimization signaling in two adjacent preset time periods, a retrieval signaling is triggered and sent to a technician, who investigates the cause after retrieval and adaptively optimizes the above steps.

[0068] Hazard analysis: When each output circuit does not trigger the load optimization signaling, the power of each output circuit corresponding to each division point within the preset time period is extracted according to the set division point, and the early warning risk model of each output circuit is constructed, and the corresponding steps are executed based on the early warning risk model of each output circuit;

[0069] Specifically:

[0070] S1: Calculate the power of each output circuit corresponding to each division point using the standard deviation formula to obtain the fluctuation value of each output circuit in a preset time period and the reference value corresponding to the preset fluctuation value. If the fluctuation value of one group of output circuits is higher than the preset reference value, it is marked as a warning output circuit, otherwise it is marked as a normal output circuit.

[0071] By comparing the fluctuation value with the preset reference value, the output circuit can be clearly divided into the warning output circuit and the normal output circuit; this helps to timely discover those circuits with large power fluctuations and potential problems;

[0072] S2: extract the power of each division point corresponding to the early warning output circuit, and arrange them in the time sequence of each division point. After the arrangement is completed, calculate the difference between two adjacent groups of power from left to right, and subtract the value on the left from the value on the right of the two adjacent groups of power; if the difference between two adjacent groups of power is a negative value, mark the negative value as a decreasing value, and if the difference between two adjacent groups of power is a positive value, mark the positive value as an increasing value; take the absolute value of all decreasing values ​​and sum them to obtain the total decreasing value; sum all increasing values ​​to obtain the total increasing value; calculate the ratio between the total increasing value and the total decreasing value, that is, the total increasing value / the total decreasing value, to obtain the power change ratio;

[0073] The power change ratio reflects the overall trend comparison of the circuit power rising and falling within the preset time period; if it is much greater than 1, it means that the rising trend is more significant and there is a hidden danger;

[0074] S3: taking the maximum power value from the powers of each division point corresponding to the early warning output circuit, and obtaining the rated power corresponding to the early warning output circuit, and calculating the ratio of the maximum power value to the rated power, that is, obtaining the power early warning ratio by dividing the maximum power value by the rated power;

[0075] The power warning ratio indicates the degree of closeness between the maximum power value and the rated power. The higher the power warning ratio, the closer the circuit is to the rated power within the preset time period, and the higher the risk of overload.

[0076] S4: using the power change ratio and the power warning ratio as the length value and the width value of the rectangle respectively, and constructing a rectangle, and using the constructed rectangle as a warning risk model of the warning output circuit within a preset time period;

[0077] S5: Calculate the area value of the early warning output circuit corresponding to the early warning risk model, and compare the calculated area value with the preset area threshold. If the area value of the early warning output circuit corresponding to the early warning risk model is higher than the preset area threshold, trigger the early warning optimization signaling;

[0078] S6: When the early warning optimization signaling is triggered, according to the transfer ratio set corresponding to the early warning optimization signaling, the maximum power value of the corresponding output circuit is multiplied by the set transfer ratio, and the power required to be transferred in advance by the output circuit is used as the power amount, and the triggered early warning optimization signaling is converted to a light load level, and step M2-201 is executed;

[0079] The triggering of early warning optimization signaling means that there is a potential risk in the circuit. By transferring part of the power in advance, the pressure on the circuit can be alleviated to a certain extent and the possibility of risk occurrence can be reduced;

[0080] Abnormality handling: When an abnormality occurs, the maintenance signaling is directly triggered and the maintenance capability values ​​of the maintenance personnel who are in working state at the current time point are analyzed. Based on the maintenance capability values ​​of each maintenance personnel, the corresponding maintenance personnel are selected to go to the location of the power distributor for processing; abnormalities include electrical connection failure, power distributor component damage failure and power distributor overheating;

[0081] Specifically:

[0082] Extract the total maintenance times of each candidate from the work log of each candidate, preset the value ranges of each group of times corresponding to the total maintenance times, and set each group of times value ranges to correspond to an experience index; the range of the experience index is set to 1-10, and the more the total maintenance times, the higher the corresponding experience index;

[0083] Matching the total maintenance times of each candidate with the preset value ranges of each group of times, thereby obtaining the experience index of each candidate;

[0084] Obtain the duration of each maintenance for each candidate. The duration starts from the time when each candidate is selected and ends when the processing is completed.

[0085] The reference duration range corresponding to the preset duration is as follows: if the duration used by the candidate for selection is within the preset reference duration range, the duration used by the candidate for selection for that time is marked as normal processing duration; if the duration used by the candidate for selection for that time is higher than the preset reference duration range, the duration used by the candidate for selection for that time is marked as delayed processing duration; if the duration used by the candidate for selection for that time is lower than the preset reference duration range, the duration used by the candidate for selection for that time is marked as early processing duration;

[0086] Count the number of advance processing time, normal processing time and delayed processing time for each candidate respectively, record them as advance number Q1, normal number Q2 and delayed number Q3, mark the total number of each candidate as Q4, according to the formula The number of advance times Q1, the number of normal times Q2 and the number of delayed times Q3 of each candidate are weighted and calculated to obtain the processing performance value QER of each candidate; wherein a1, a2 and a3 are the influencing weight factors of the number of advance times Q1, the number of normal times Q2 and the number of delayed times Q3 respectively;

[0087] The processing performance value QER of each candidate is multiplied by the experience index to obtain the maintenance capability value of each candidate; the candidate with the largest maintenance capability value is selected as the maintenance personnel who triggers the maintenance signaling this time, and the location of the power distributor is sent to the maintenance personnel;

[0088] In summary, the processing performance value is multiplied by the experience index to obtain the maintenance capability value, and then the candidate with the largest maintenance capability value is selected. This comprehensive evaluation method takes into account both the experience of the personnel and their recent actual work performance, making it more likely that the selected maintenance personnel will efficiently and accurately handle abnormal situations of the power distributor;

[0092] The allocation module is used to detect the power of the power supply equipment and classify the area, calculate the total power demand of the equipment in each area, and allocate the input power according to the total power demand;

[0093] The evaluation module is used to monitor and analyze the load conditions of each output circuit of the power distributor in real time according to the preset time period, trigger the load optimization signaling in the current preset time period based on the analysis results and execute corresponding steps to adjust the power distributor;
