FAULT DIAGNOSIS AND RESTRUCTURING SYSTEM AND METHOD BASED ON EVENT-VALUE AGREEMENT

Abstract

The invention relates to a system and method for identifying faults occurring in industrial data collection lines. Within the scope of the invention, data relating to the industrial machine (40) is received via independent value channels and event channels. The technical roles of the variables in the value channel are determined, and the type of event to be sought in the event channel and the information that should be present in the event are determined using the change conditions specific to these roles. The changes in the value channel and the events received from the event channel are compared in terms of time and content to identify missing events or content mismatches. The health status of the value channel and the event channel is evaluated together with these mismatches, and the fault is determined as an event generator fault, a label matching fault, or a connection fault. Depending on the determined fault type, the event generation parameters, the label matching table (23), or the communication link can be rearranged.

The identified discrepancy is not considered merely as a matter of error; the health status of the value channel and the event channel is considered separately The source of the malfunction is being determined. Although the signal channel is healthy, 10 The failure of the expected event to occur is due to a manufacturer's fault; the nature of the event that occurred... the information is inconsistent with the values ​​in the value channel or the event channel The label matching failure occurs when the value channel fails to provide appropriate data during operation. If both channels cannot provide data simultaneously, this is called a connection failure. They can be correlated. Thus, different techniques can be used on the same data collection pipeline. 15 This allows for the different types of malfunctions that may result from various causes to be distinguished. The source of the malfunction identified within the scope of the invention will be redesigned. It is used in selecting the structure. The event involves identifying the manufacturer's fault. In this case, thresholds, weights, or minimum broadcast intervals related to event generation are considered. The parameters can be changed; if a label matching malfunction is detected. The PLC tag to which the relevant variable is associated, candidate PLC for the same machine. re-evaluated by considering the value progression behavior of the labels can be determined; if a connection fault is identified, communication will resume. Sessions and data subscriptions can be re-established. Thus, with fault diagnosis, 25 Technical correction processes are linked together within the same workflow. The invention also includes events that cannot be captured during live operation. obtained from historical event information available on the server and the said It is possible to include these events in the current assessment. This 30 In this situation, events from the past and events captured live are the same. 12 The situation is evaluated using rules and event-value agreement is reassessed. It can be accomplished. The primary purpose of the invention is to identify the value and event channels relating to the same industrial process. by checking their consistency with each other during the study, only 5 of the channels one of them is still working or one of the channels is with an incorrect data source situations that arise when associated with traditional connection controls The aim is to enable the detection of faults that are difficult to identify.

As shown in Figure-1, the invention relates to the values ​​of the industrial machine (40). and obtaining information through independent channels, value Identifying the events expected to occur as a result of changes in the channel, word 10 The subject is expected events, events that occurred, taken from the event channel. Comparison of identified discrepancies in the health status of both channels taking into consideration the source of the fault and converting it to the identified source of the fault. based on the principle of restructuring the relevant section of the data collection pipeline. It is based on. 15 Fault diagnosis and reconstruction system (10); at least one processor (11), at least one memory (12), database (13), communication module associated with the processor (11) (14) and data collection module (15). The system (10) includes the communication module. (14) exchanges data with the server (20). The server (20) exchanges data with the server (20). values ​​and events relating to the industrial machine (40) via PLC (30) or It can receive data from the data infrastructure associated with the PLC (30). Industrial machine (40), machine that performs a physical operation on the production line, It refers to production equipment, process equipment, or a part thereof. 25 PLC (30) monitors the operating status, production quantity, and rejection of the industrial machine (40). regarding quantity, speed, perception status, or other operational variables It contains PLC labels (31) that include information. PLC label (31) is located inside the PLC (30) and is used to send 30 to the industrial machine (40). a data address that represents a numerical, logical, or categorical value related to a given value A PLC tag (31) displays, for example, the cumulative production quantity, cumulative rejection quantity, detection count, machine operating status, machine speed, detection It can represent the mode or a dataset parameter. The server (20) presents the values ​​obtained from the PLC labels (31) to the clients. and specific situations or changes occurring in industrial machinery (40) 5 It can generate counter events. In an application, the server (20), OPC UA It can be implemented as a server that supports the communication infrastructure. However, the invention is not limited to a specific communication protocol. The event generator (21) is 10 that runs on or is associated with server (20). and refers to the software function that generates an event depending on specific process conditions. The event producer (21), for example, production takes place, rejection takes place, machine status change, shutdown completion or detection mode It can generate the relevant event upon modification. Used in event generation. 15 such as threshold, weighting factor, minimum broadcast interval or event type link The parameters can be configurable. The historical data store (22) is accessed retrospectively by the server (20). Refers to the storage structure in which stored value and / or event information is kept. The historical data repository (22) can be found in the server (20) as well as 20 also in a separate storage infrastructure accessible by the server (20) It can be found. The label matching table (23) is the table of variables located on the server (20) and their The source PLC labels (31) define the connections between them. Thus, 25 on the server (20) a specific production counter, status value or other variable It is determined from which PLC label (31) the information provided was obtained. Label A faulty connection in the mapping table (23) causes data on the server (20) Despite being found, the data in question incorrectly represents the physical variable. This can cause it to... 30 16 Data collection module (15) obtains values ​​from the server (20) via the value channel. The values ​​and events received through the event channel are the same. The evaluation is collected within a time interval. The value channel is periodic. numerical data obtained through reading, data change notification, or similar method or may include categorical variables, and the event channel is the server's (20) 5 It can include event notifications that it has generated. The processor (11) examines the variables located in the server's (20) address space. It determines the technical roles of the variables in question. The technical role in determining the variable, the noun path and especially the 10 in the noun path suffix Descriptive information can be used. The suffix of the noun path, the end of the noun path. section or one or more preceding sections along with the final section It can represent the final part consisting of sections. In this context, a variable is; cumulative production counter, cumulative rejection counter, cumulative detection counter, machine 15 such as status, machine speed, detection mode, dataset definition or dataset value It can be associated with one of the technical roles. The identified technical role is the one in question. Which evaluation rule determines the behavior of the variable in the value channel? It is used to determine which one will be examined. During the examination of the address space, the variables are represented by a root of 20 representing the machine. Navigation can begin from a specific point. In an application, navigation is width-prioritized. It can be carried out as such and relates to more than one industrial machine (40) Nodes can be queried collectively. A name path can have multiple nodes. A longer and more specific match if it matches the defined final section. It is available for use as a priority. 25 The defined technical role is not only used in the classification of the variable, also, which technical rule describes the change occurring in the value channel? It determines how it will be applied. Thus, different types of variables are applied in the same way. Instead of evaluating it with the change rule, it should be evaluated using the production counter, machine status, and speed 30. or variables such as detection mode are appropriate to their own technical behavior. It is examined according to the rules. 17 Values ​​obtained from the value channel over a specific time window This is exemplified by obtaining data from the event channel within the same time window. The events that occur are also collected. The processor (11) determines the value series. by examining the changes according to the transition rules of the relevant technical role, this change is 5 whether there is an event that should occur as a result It determines. The determined event is used as the expected event, and the event... in terms of time and content, with events actually taken from the channel. They are being compared. If a variable, defined as a cumulative counter, decreases, the cumulative counter will show a decrease. The PLC is malfunctioning because the counter does not advance backward during normal operation. (30) restart, counter overflow or variable incorrect PLC The possibility of linking to the label (31) can be determined. The same decline in succession In order to prevent a large number of identical findings, the situation in question is 15 It can be reported only once. In the case of an increase in cumulative production or rejection counter, the increase in question A counter-production or rejection event is expected to occur. What happened... the cumulative total value contained within the event, 20 around the time of the event It can be compared with value examples. The absence of an event is a missing event. as, the total value within the event in the relevant time interval If it falls outside the scope of those values, it is considered a content mismatch. can be evaluated. In this context, sampling interval is p, evaluation time window is W, and event is... Minimum broadcast interval Tmin and the minimum broadcast interval applied to the type The coefficient can be defined as k. The cumulative counter increases, but the corresponding... If the incoming event cannot be found, a decision of missing event is made only if; W ≥ Tmin × k 30 It is created if the condition is met. Thus, the evaluation Normal broadcast that can be implemented by the event generator (21) of the time window 18 the absence of the event when the length is not sufficient compared to the delay. It is not considered a direct malfunction. In response to the cumulative meter increase. In the case where the event exists, the cumulative total carried within the event The value is the minimum of the sample values ​​found around ±τ of the event time. compared with maximum values; the event value is 5 of the range in question. Being outside of this context is considered a content mismatch. In practice, the time tolerance can be defined as τ = 3p + 2 seconds. Transition from state one to state two in the variable representing the machine state. When this occurs, a state change event corresponding to this transition is 10 It is expected to happen. Although the event has occurred, the event the value channel of the previous state or new state information contained within Content mismatch can be identified if the observed transition does not match the content. In one application, the time tolerance used in this evaluation is τ = 3p + 2 It can be set in seconds. 15 The machine being switched from a running state to a stopped state and then back to a running state. In a situation where the transition occurs, the duration of the pause is the state in the value channel. It can be calculated from the changes. A stance is completed when the stance is finished. 20 contains information about the occurrence of the event and the duration of the hearing regarding that event. This can be expected. The time found in the event and the time calculated from the value channel. A time discrepancy can be identified when the difference between the two exceeds a defined tolerance. The absence of expected areas such as the reason for the stance or the root cause is another separate issue. This can be considered a deficiency. The time tolerance for a stop event is defined in one application as τ = 3p + 5 seconds. It can be determined. The time to be applied in comparing the hearing duration. The tolerance is 10% of the downtime calculated with a value of 3p + 5 seconds. It can be determined as the value that is greater than the other. In other words... The time tolerance, with a downtime of D, is 30. maximum (3p + 5 seconds, 0.10 × D) It can be determined in this way. 19 The transition occurring in the variable representing the detection mode, the detection mode This may require the occurrence of an event related to the change. The transition The absence of the relevant event within the defined time tolerance is a deficiency. can be considered as an event. In an application, the time in question The tolerance can be defined as τ = 3p + 2 seconds. 5 The machine speed should be zero when the machine is marked as running. or deviation from the defined stability range is a warning regarding the value channel. It can create. Machine statuses that will be considered as working. In applications where it is not defined as machine-specific, 10 depending on the operating condition. Speed ​​and braking controls may not be applicable. The variables in the datasets, and the parameters used, relate to the respective dataset. Their definitions can be compared. The parameters are compared with the defined dataset. If there is a discrepancy, the discrepancy in question can be identified. 15 Quality information from nodes in the value channel is used in determining channel health. It is used. The quality is valid within the evaluation time window. the absence of a sample, intermittently invalid quality, no sample at all Failure to obtain the value or the value not showing the expected change indicates a value channel of 20. This constitutes input for the health assessment. The health status of the event channel. and whether the relevant events were received within the evaluation time frame and is the information found in the received events consistent with the values ​​in the value channel This can be determined by taking into account that it is not present. The processor (11) compares the expected event with the actual event. the identified conflict, along with the health status of the value channel and the event channel. It evaluates the fault. As a result of this evaluation, the fault is determined to be a manufacturer's fault. This can be identified as a label matching failure or a connection failure. Despite the value channel being healthy and the expected change being observed. If the relevant event is not received, the data source continues to operate. However, the event could not be generated as expected by the producer (21). It can be determined and the situation can be attributed to a manufacturer's fault. Even though the value channel is healthy and the event is received, the event carries... If the value does not match the relevant value series, the event generator (21) and the value Since the channel may be fed from different PLC tags (31), tag matching 5 The fault can be identified. Similarly, a valid example in the value channel. even though it is not present or the value remains constant, events are taken into consideration. continuation of the value variable to an inappropriate PLC label (31) This can be considered an indication that they are connected. Both the inability to obtain a suitable sample from the value channel and the inability to obtain an event sample from the event channel. If it cannot be obtained, the server (20), PLC (30) or between them It can be determined that there is a connection problem in the communication structure, and the situation This can be associated with a connection failure. The cumulative counter decreases. In this case, the label matching failure requires restarting the PLC (30) or the counter 15 The possibilities of flooding are being assessed. A healthy value channel involves identifying the event that occurred and understanding the content of that event. If it is consistent with the value series, then the relevant value and the event are in agreement. is determined. 20 Depending on the type of fault identified, the system has (10) different technical configurations. It is possible to change it. In case of manufacturer failure, the incident is reported to the manufacturer (21) related evaluation thresholds, weighting coefficients, minimum broadcast interval or event The type of connection can be changed. Thus, the relevant process change event generator 25 (21) can ensure that the event is correctly reconverted. In case of label matching failure, the link in the label matching table (23) It can be redefined. For this purpose, the candidate belonging to the same industrial machine (40) The time progression behavior of PLC labels (31) can be examined. 30 and candidate PLC label that is consistent with the values ​​of the event that occurred (31) It can be determined. If a suitable candidate is found, the relevant server variable will be used. 21 The source PLC label (31) can be replaced with the said candidate; sufficient compatibility If no suitable candidate is found, the relevant variable is considered suspicious. It can be marked. In case of connection failure, the server (20) is contacted via the communication module (14). The established session can be recreated and values ​​or events can be retrieved. Existing subscriptions can be re-established. Specified within an application... Diagnostic information regarding the fault is entered into a diagnostic variable on the server (20). It can be written. If a specific type of event cannot be detected during live operation, the system (10) can query the historical data repository (22). Determined within this scope Event information relating to the past time interval is received from the server (20) and live The events observed during the study were included in the evaluation. The source of events obtained from the historical data repository (22) is 15 The relevant comparison rules can be reapplied while being preserved. The server's (20) If the questioning of past event information does not support the wording The issue is not a communication failure, but rather a malfunction of the server's relevant function. as a system limitation resulting from lack of support It can be evaluated. 20 Database (13); samples received from the value channel, events that occurred, identified expected events, comparison results, channel health information, identified failure types, implemented restructuring procedures, and the system It can store the parameters used during its operation. Memory (12) is 25 program instructions executed by the processor (11) during operation temporary values ​​used, technical role definitions, transition rules, and It can include evaluation parameters. In a sample application, the sampling interval was p = 2 seconds, and the evaluation time was 30 seconds. The window is set to W = 10 minutes, or 600 seconds. Cumulative The production counter changes from 100 to 105 within the specified time window. 22 its value is progressing, however the corresponding production event in the event channel It is not available. The minimum broadcast interval Tmin = for the relevant event type. The coefficient applied to the seconds and minimum broadcast interval is k = 2. When it is accepted that this is defined, in order to form a decision on missing facts... Condition to be applied; 5 W ≥ Tmin × k This is the case. Accordingly; Tmin × k = 30 seconds × 2 = 60 seconds It is calculated as follows. The evaluation time window is W = 600 seconds. because; 10 600 seconds ≥ 60 seconds The condition is met. Therefore, the event is the minimum publication granted to the producer (21). Although there was sufficient observation time in terms of duration, production Failure to record any production event corresponding to the increase in the counter is a missing event. It is determined as follows: 15 samples in the value channel have valid quality. and the production counter's time window ranges from 100 to 105 The value channel is considered healthy because of its progression towards the expected value; If the event is not found, it is attributed to a manufacturer defect. In the same example, the value and the time of the events that occurred are 20. When comparison is needed, the sampling interval should be p = 2 seconds. Due to the time tolerance, using the relation τ = 3p + 2 seconds, we get τ = 8 seconds. It can be determined as follows. A production event occurring in another application takes place at 12:00:10 and is 25 The cumulative total is 103. The sampling interval is two Since it is a few seconds, when the time tolerance is set to eight seconds, The sample values ​​between 12:00:02 and 12:00:18 are being examined. Although the values ​​in the time interval were between 107 and 108 If the event that occurred has a value of 103, then the value series of the event content is 30. It is determined that the content falls outside the minimum and maximum values. 23 A conflict is created. If the value channel is healthy, then the word This issue may be related to a label matching malfunction. In another application, the status of the industrial machine (40) was at 12:05:00. It is switching from working to stopped state and will restart at 12:05:47. The employee is returning to the working state. The actual downtime determined from the value channel is 5. In this case, D = 47 seconds. The standstill event occurred at 12:05:49. It is coming, but the time value within the event is 12 seconds. It is reported. If the sampling interval is p = 2 seconds, then the value of 3p + 5 seconds is 11 10 It is calculated in seconds. Ten percent of the actual downtime is 4.7 It is seconds. Since the time tolerance is set as the larger of these two values, it is 11. The actual stopping time differs from the time reported during the incident. Since the difference is 35 seconds, the difference in question has a tolerance of 11 seconds. It exceeds the limit and a time discrepancy is identified. 15 Thanks to this structure, the system (10) can only use one value channel or only one value channel. It is not limited to checking whether the event channel is working; it also two independent channels representing physical process behavior in different ways to ensure that they corroborate each other, the technical source of the identified dispute 20 isolating and collecting relevant data depending on the identified source of the failure or It is possible to reorganize the communication configuration.
