The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.
According to one aspect of the application, a communication equipment operation risk early warning method is provided, and the method can be applied to a communication management system, particularly a power communication management system.
Referring to fig. 1, fig. 1 is a schematic flow chart of a method for early warning of operational risk of a communication device according to an embodiment of the present application. As shown in fig. 1, the method for early warning of operational risk of a communication device in this embodiment may include the following steps:
and S101, extracting historical operation information of the target communication equipment from the acquired work order information based on a preset information extraction rule, wherein the historical operation information is continuously updated according to the continuation of the life cycle of the target communication equipment.
Specifically, the information extraction rules may be preset differently according to different types of work orders, for example, the work orders include repair orders, defect fault orders, work contact orders, risk pre-warning orders, and the like. Taking the communication defect list as an example, the information in the communication defect list generally includes options such as a work order number, a filling time, a title, a defect filling person, a filling person contact phone, a defect reporter, a defect source, a defect type, a defect description, and the like, and the information extraction rule for the communication defect list includes: (1) setting the options of 'defect source, defect type and defect description' as target options of information to be extracted; (2) extracting information of a text in a target option by using a pre-constructed word and sentence template, extracting keywords or/and keywords/key phrases and the like from the text based on a matching corresponding relation between the template and the text, wherein one of the templates is 'XX found XX fault', defect description is 'national network communication scheduling monitoring found main power module fault with national network number 1', the defect description content is matched and corresponding based on the template, and the extracted content from the text comprises: "national network communication scheduling monitoring" and "the main power module with national network number 1"; (3) the extracted content is segmented by using a segmentation technology, which can be the existing technology, for example, the ' national network communication scheduling monitoring ' and the ' main power module with the national network number 1 ' are segmented to obtain the ' national network communication ', ' scheduling monitoring ', ' national network number 1 ', ' and ' main power module '.
Of course, the above is only an example, and for different types of work orders, the information extraction rule may be adaptively adjusted, and may refer to the existing extraction rule of text information or web page information.
The historical operation information of the target communication equipment can comprise operation records of the target communication equipment, and the operation records comprise record information of at least one process of commissioning, operation, defect and fault, overhaul, technical improvement and overhaul, hidden danger, bearing mode, quit operation and scrapping of the target communication equipment.
Wherein the target communication device may refer to one or more communication devices having a unique number or belonging to the same type. It should be noted that the communication device herein may include a board card often mentioned in the art, in addition to a common switching power supply, a storage battery, a UPS (uninterruptible power supply), an optical cable, and the like.
The communication device lifecycle may refer to a time period of a continuous state of the communication device including engineering, operation, and decommissioning processes. The historical operation information is continuously and automatically updated according to the continuation of the life cycle of the target communication equipment and is automatically stored in the communication management system.
Optionally, referring to fig. 2, fig. 2 is a schematic flowchart illustrating step S101 according to an embodiment of the present disclosure. According to fig. 2, the step S101 may include:
step S1011, based on the preset information extraction rule, automatically extracting the operation index information of the target communication device according to the work order table pre-created in the communication management system and corresponding to each state in the operation process of the target communication device and the data of each work order table uploaded by the user and received by the communication management system.
Specifically, the operation index information may include, for example, at least one of an index name, an index factor, equipment operation evaluation content, an evaluation percentage corresponding to each item of equipment operation evaluation content, and a weight corresponding to each item of index name. The index names comprise aging degree, defect statistics, inspection maintenance, port occupancy rate and the like; the index factors comprise the operation age of the equipment, the number of defect lists, the inspection and overhaul number of overhaul lists, the overhaul number of overhaul single engineering, the light plate occupancy rate and the like; the operation evaluation content of the equipment comprises that the operation age of the equipment is within 5 years, the defect list of the same board lacking in the equipment within half a year is within 2 times, and the like.
The preset information extraction rule may be as described above, and different extraction rules are adopted according to different types of work order tables to extract the operation index information in the work order table. The work order table can be a template type empty table, and data in the work order table can be uploaded by a person through a computer or can be automatically calculated and stored by the computer.
Step S1012, performing automatic statistical analysis on the automatically extracted operation index information to obtain operation state information of the target communication device, where the operation index information and the operation state information are continuously statistically updated according to the continuation of the life cycle of the target communication device.
Specifically, the operating state information includes, for example, description information for characterizing the operating health condition of the equipment, and more specifically, includes, for example, information such as a health condition grade, a health condition description, and the like, wherein the health condition grade is classified into, for example, healthy, relatively healthy, sub-healthy, unhealthy or slight fault, ill or faulty, severely ill or severely faulty, and the like; wherein the health condition description for example comprises: the method comprises the steps of ' good health condition ', ' good monitoring condition, suitability for long-term operation ', ' abnormal condition, unsuitability for long-term continuous operation ', ' serious abnormal condition, adjustment measure ' occurrence ', ' serious abnormal condition, shutdown maintenance in a short time ', ' no operation, immediate shutdown maintenance ' and the like.
In one example, a calculation formula may be preset, statistical calculation may be performed based on the preset calculation formula and the corresponding operation index information extracted automatically, and the operation state information of the target communication device may be obtained according to a score of a calculation result. For example, the operation index calculation result of a certain device is represented by r, and the aging degree l and the device alarm j are used as calculation elements, the value of r is calculated by using the following formula: r ═ l × 40% + j × 60%, where the value of l may be automatically obtained by a computer, for example, further based on records or statistics of the operating age of the plant, and the value of j may be automatically calculated, for example, further based on a weighted average of the number of alarms history for different types of plant operation. After the value of r is obtained, the operation state information of the target communication device can be obtained according to the comparison between the value of r and one or more preset thresholds and further according to the comparison result. For example, if r is greater than a preset threshold, it is obtained that the target communication device is in a healthy state, if r is less than the preset threshold and greater than another preset threshold, it is obtained that the target communication device is in a relatively healthy state, and so on, and the operation state information corresponding to the target communication device is obtained.
Step S102, based on historical operation information of the target communication device, determining familial defects of the target communication device.
Specifically, the familial defect information of the communication device is information well known to those skilled in the art, and includes, for example, an average annual defect rate of the device, a specific part where a defect occurs, and the like. For example, based on the operating age of a certain device, the contained components, the device model and the annual average defect rate of the similar device, the probability of the certain type of defect occurring in the target communication device is calculated by using a preset calculation formula, and by analogy, the multi-type defect probability information of the target communication device is obtained, and the multi-type defect probability information is used as the familial defect information of the target communication device. Of course, this is merely an example, and other existing computing methods or techniques may be employed to derive the familial defect information for the communication device based on existing historical operational information.
Optionally, referring to fig. 3, fig. 3 is a schematic flowchart illustrating step S102 according to an embodiment of the disclosure. According to fig. 3, the present step S102 includes:
and step S1021, acquiring familial defect information of other communication equipment matched with the target communication equipment in the communication management system according to a preset matching rule.
Specifically, the other communication devices matched with the target communication device may be retrieved by inputting various device parameters of the target communication device, for example, by inputting the model, the operating life, and the contained component name of the target communication device, the other communication devices most similar to the various device parameters of the target communication device are retrieved from the communication management system, and further, in the case of determining the matched communication device, the familial defect information of the matched communication device is acquired.
Step S1022, determining the familial defect of the target communication device based on the familial defect information of the other matched communication devices and the historical operation information of the target communication device.
Specifically, for example, when obtaining the familial defect information of the other communication device that matches, the familial defect information of the target communication device is obtained by comparing various device parameters of the target communication device and the other communication device and correcting the familial defect information of the other communication device according to the comparison result. For example, if the target communication device and other communication devices have the same device parameters except for the operating life, the correction coefficient may be obtained according to the comparison of the operating life, for example, the ratio of the operating life is directly used as the correction coefficient, and then the correction coefficient is multiplied on the basis of the familial defect information of the other communication devices to obtain the familial defect information of the target communication device. Of course, this is only a very simple example, and in practice, a corresponding correction formula or correction method, which may be adopted or referred to in the prior art, will be set up according to specific situations, so as to better determine the familial defect of the target communication device.
Optionally, the familial defect includes a defect probability a of the target communication device, the defect probability a being calculated according to formula (1),
a＝k1×a1+k2×a2+……+kn×an (1)
wherein a1 and a2 … … an represent the weight of the defect probability corresponding to each device parameter of the target communication device in the defect probability of the target communication device, the sum of a1 and a2 … … an is equal to 100%, and k1 and k2 … … kn represent the defect probability of each device parameter of the target communication device, wherein the defect probability of each device parameter is obtained by calculating the product of the ratio of the device parameter of the target communication device to the corresponding device parameter of the other communication device matched with the target communication device and the known defect probability of the other matched communication device. The equipment parameters include, for example, the operating age of the equipment, the number of historical defects, the number of historical repairs performed, and/or other parameters that are common in practice.
Specifically, for example, the device parameter of the target communication device includes two items, that is, a device operating age and a number of occurrence of the historical defect, where a numerical value of the device operating age is 3, the number of occurrence of the historical defect is 4, defect probabilities corresponding to the two items respectively account for 40% and 60% of the defect probability of the target communication device, a known defect probability of the other communication device matching the target communication device is 85%, an operating age of the other matching communication device is 2, and the number of occurrence of the historical defect is 5, and then the defect probability a of the target communication device is 40% × 3/2 × 85% + 60% × 4/5 × 85% × 0.51+0.408 is 91.8%. Thereby, a more accurate and more reliable device defect probability is obtained based on an integrated analysis of a plurality of device parameters of the target communication device and the matched other communication devices.
And S103, early warning aiming at the operation risk of the target equipment according to the determined familial defect.
Specifically, when obtaining the familial defect information of the target communication device, it is possible to determine, based on the defect information of the target device, such as the level and probability of the risk of occurrence of the familial defect, on what date the target device does not need to send an early warning to the department in charge of the device, and on what other date the target device needs to send an early warning of what content at what level to the department in charge of the device, so as to improve the operational reliability of the device.
For example, when the defect probability of the target device exceeds 60%, an early warning message is sent to a corresponding communication terminal (e.g., a mobile phone) of a person responsible for the target device to remind the person responsible for the target device to strengthen daily maintenance of the target device.
