Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The method for determining the video of the double-disk test can be applied to the application environment shown in fig. 1. Wherein the video recorder 102 communicates with the server 104 over a network. When the video recording operation is determined to be triggered to start, the video recorder 102 may estimate an estimated test duration required for executing the target nuclear power test, and set the recorded target test video as a test video to be copied when the actual recording duration is not matched with the estimated test duration. The video recorder 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices having a video recording function, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.

In one embodiment, as shown in fig. 2, a method for determining a multi-disc test video is provided, which is described by taking the method as an example for being applied to the terminal in fig. 1, and includes the following steps:

and step S202, acquiring the bound test ticket number when the video recording operation is triggered to start.

Specifically, when a tester clicks a recording start control in the video recorder, the video recorder acquires the bound test ticket number. The test ticket number is an identification code used for determining a nuclear power test, and specifically can be a graphic code, such as a two-dimensional code or a bar code. In the embodiment of the application, the test ticket number may be a two-dimensional code or a bar code generated according to test information of a nuclear power test. The test information refers to information associated with the nuclear power test, and the test information may specifically include a test identifier of the nuclear power test, a test work order associated with the nuclear power test, and the like. The test work order is a form recorded with the process information of each test process in the nuclear power test; the process information may specifically include a person identifier of a tester who performs the test process, an executable procedure of the test process, an equipment part keyword corresponding to the test process, and the like.

In one embodiment, the step of binding the video recorder to the test ticket number comprises: when the pickup operation of the recorder is triggered, determining the target personnel identification of the target test personnel triggering the pickup operation; acquiring a target test ticket number based on the target personnel identification and a preset test work order, wherein the target test ticket number is obtained by screening from a candidate test ticket number set, and the candidate test ticket number set comprises test ticket numbers corresponding to nuclear power tests to be executed; when the scanning operation aiming at the target test ticket number is triggered, determining a target recorder for scanning the target test ticket number; and establishing an incidence relation among the target recorder identification, the target personnel identification and the target test ticket number of the target recorder.

Specifically, before a nuclear power test is carried out, a target tester can go to a warehouse to pick up a video recorder, and when the video recorder is picked up, a picking control in a recorder management terminal is clicked, so that the recorder management terminal is triggered to call a camera of the local computer to collect a face image of the target tester, the face image is subjected to face recognition, and a target person identification is determined. When the target personnel identification is obtained, the recorder management terminal pulls the test work order corresponding to each nuclear power test to be executed from the server, and inquires the target test procedure to be executed by the target test personnel corresponding to the target personnel identification from the test work order. Further, the recorder management terminal inquires a target test identification of a target nuclear power test including the target test procedure from the test work order according to the target test procedure, sends the target test identification to the server, and the server screens out a target test ticket number corresponding to the target test identification from a preset candidate test ticket number set according to the target test identification and returns the target test ticket number to the recorder management terminal.

When the recorder management terminal receives the target test ticket number, the recorder management terminal correspondingly displays the target test ticket number, so that a target tester can scan the target test ticket number through the acquired video recorder, when the scanning is confirmed to be successful, the recorder management terminal can acquire the target recorder identification of the video recorder through scanning operation, establish the incidence relation among the target recorder identification, the target personnel identification and the target test ticket number, and send the incidence relation to the server, so that a subsequent video recorder can pull the bound test ticket number from the server according to the recorder identification of the recorder.

In one embodiment, before a nuclear power test is executed, the server may obtain test information of the nuclear power test to be executed, generate a corresponding test ticket number according to the test information, and store the test ticket number in correspondence with a test identifier of the nuclear power test. It is easy to understand that, within a certain time period, there may be a plurality of nuclear power tests to be executed, so that a corresponding test ticket number may be generated for each nuclear power test to be executed, and the generated plurality of test ticket numbers are combined to obtain a candidate test ticket number set. Before the nuclear power test is executed, the server can obtain a test identifier of the nuclear power test to be executed and process information of each test process in the nuclear power test to be executed, and a test work order is generated according to the test identifier and the process information.

And step S204, analyzing the test ticket number to obtain process information corresponding to each test process in the target nuclear power test to be recorded.

Specifically, the video recorder analyzes the test ticket number bound by the preset analysis rule to obtain a test work order of the target recorder to be recorded, and reads process information corresponding to each test process in the target test from the test work order. The preset analysis rule can be correspondingly set according to the encoding rule of the test ticket number.

In one embodiment, the test ticket number records the total number of the test sub-identification codes; analyzing the test ticket number to obtain process information corresponding to each test process in the target nuclear power test to be recorded, wherein the process information comprises the following steps: analyzing the test ticket number to obtain a plurality of test sub-identification codes; when the number of the plurality of test sub-identification codes accords with the total number of the test sub-identification codes, determining the respective corresponding analysis mode of each test sub-identification code according to the analysis serial number in the test sub-identification codes; and analyzing the corresponding test sub-identification codes in an analyzing mode to obtain process information corresponding to each test process in the target nuclear power test to be recorded.

Specifically, in the process of generating the corresponding test ticket number according to the test information of the nuclear power experiment, the server can determine the components of the test information, encode each component by using different encoding modes to obtain the test sub-identification codes corresponding to each component, and combine the test sub-identification codes to obtain the test ticket number. For example, when the test information includes a test name of the nuclear power test and a work order identifier of a test work order, the server encodes the test name according to an encoding rule A, and adds an analysis serial number corresponding to the encoding rule A to the encoded test name to obtain a first test sub-identifier; the server encodes the work order identification of the test work order according to the encoding rule B, and adds the analysis serial number corresponding to the encoding rule B to the encoded work order identification to obtain a second test sub-identification code; and the server combines the first test sub-identification code and the second test sub-identification code, and adds the total number of the test sub-identification codes to obtain the test ticket number.

Furthermore, when the test ticket number needs to be analyzed, the video recorder splits the test ticket number into a plurality of test sub-identification codes, counts the number of the split test sub-identification codes, and analyzes the test sub-identification codes when the number of the split test sub-identification codes is equal to the total number of the test sub-identification codes. The video recorder determines an analysis serial number in the current test sub-identification code, determines a corresponding analysis scheme according to the analysis serial number, analyzes the current test sub-identification code according to the determined analysis mode to obtain a corresponding work order identifier, and reads process information corresponding to each test process in the target nuclear power test to be recorded from the test work order corresponding to the work order identifier.

Different components in the test information are coded through different coding modes, so that the coded test ticket number is safer. The number of the test sub-identification codes is in accordance with the total number of the test sub-identification codes, and the test sub-identification codes are analyzed, so that the analysis accuracy of the test sub-identification codes can be improved.

And S206, estimating the test duration of the target nuclear power test according to the process information corresponding to each test process to obtain the estimated test duration.

Due to the complexity of the nuclear power test and the uncertainty of the field environment, the test time consumed by the same nuclear power test in repeated execution may be different, so the test time required by the nuclear power test can be estimated according to the process information corresponding to each test process in the nuclear power test, so that the quality of the actual test condition of the nuclear power test can be judged according to the estimated test time in the following process.

Specifically, when the process information corresponding to each test process is obtained, the process information corresponding to each test process is input into the pre-trained duration estimation model by the video recorder, and the ideal execution duration corresponding to each test process is output by the pre-trained duration estimation model, so that the ideal execution durations can be overlapped by the video recorder to obtain the estimated test duration. The duration estimation model is a machine learning model, and the machine learning model can adopt a neural network model, a dual path network model (DPN), a support vector machine or a logistic regression model, and the like.

In one embodiment, a test procedure may include a plurality of executable steps. The duration estimation model can determine the execution duration required by each executable step according to the executable steps recorded in the process information of the current test process, and superpose the execution duration required by each executable step to obtain the execution duration of the current test process. The method for determining the execution time length required by the current executable step comprises the following steps: and extracting the operation key words and the part key words in the current executable step by the duration estimation model. The operation keywords are keywords indicating operation information of the executable steps, for example, the operation keywords may be specifically "open", "close", "unscrew", and "release" which are equal to operation-related words; the part key words are key words indicating parts of the equipment which can perform the tests required by the steps, for example, the part key words can be specifically "valve", "condenser pipe", "evaporator", and the like. The time length estimation model estimates the execution time length required for executing the current executable step according to the operation key words and the part key words, for example, the execution time length required for executing the current executable step is estimated according to the 'opening' and 'condenser pipe'.

In one embodiment, when the duration estimation model needs to be trained, a developer acquires a large amount of procedure information of the testing procedure from the network, and takes the procedure information of the testing procedure as a training sample. The method comprises the steps that a developer marks an ideal execution time corresponding to a test procedure in a training sample to obtain a sample label, the training sample and the corresponding sample label are input into a time estimation model to be trained, the time estimation model to be trained learns the execution time corresponding to the training sample based on the sample label, and therefore the estimated test time can be determined subsequently according to the execution time of the test procedure obtained through learning.

In one embodiment, the duration estimation model may be a general machine learning model with feature extraction capability that has been trained. The general machine learning model is not good when being used for extracting a specific scene, so the general machine learning model needs to be further trained and optimized through samples special for the specific scene. In this embodiment, the computer device may obtain a model structure and model parameters according to a general machine learning model, and import the model parameters into the duration estimation model structure to obtain a duration estimation model with the model parameters. The model parameters of the duration estimation model are used as the initial parameters of the training duration estimation model in the embodiment to participate in the training.

And S208, obtaining a first time threshold according to the estimated test time, and determining the extra time required for completing the target nuclear power test according to the current test data of the target nuclear power test when the estimated test time is reached.

And step S210, when the extra time length is greater than or equal to a first preset time length threshold value, setting the target test video as a test video to be copied.

Due to the uncertainty of the field environment, the actual execution time consumed by the nuclear power test in the actual execution process may not be the same as the estimated test time, so that the nuclear power test in which the time difference between the actual execution time and the estimated test time is greater than the first time threshold value can be judged as an abnormal nuclear power test, and the test video recorded in the test process aiming at the abnormal nuclear power test is set as a test video to be copied; and judging the nuclear power test with the time difference between the actual execution time length and the estimated test time length smaller than or equal to the first time length threshold value as a normal nuclear power test, and at the moment, copying the test video recorded in the test process of the nuclear power test is not needed.

Specifically, the video recorder obtains a first time threshold according to the estimated time, for example, the estimated time is multiplied by a preset percentage to obtain a first preset time, or determines a current first time threshold corresponding to the current estimated time according to a preset correspondence between the estimated time and the first time threshold. The first time-length threshold value needs to be reasonably set, when the first time-length threshold value is too long, the abnormal nuclear power test is easily set as the normal nuclear power test in a wrong mode, and when the first time-length threshold value is too short, the normal nuclear power test is easily set as the abnormal nuclear power test in a wrong mode.

The video recorder determines the test duration of the target nuclear power test according to the moment of triggering the video recording operation and the current moment, and judges whether the test duration reaches the estimated test duration. When the test duration reaches the estimated test duration, the fact that the testers do not complete the target nuclear power test video within the estimated test duration is shown, at the moment, the video recorder obtains current test data of the target nuclear power test input by the testers, and extra duration needed for completing the target nuclear power test is predicted according to the current test data. For example, when the target nuclear power test is a test for the evaporator, and the current test data represents that the evaporator test fails, the video recorder may determine, according to the current test data, that the extra time is a test time required for performing the evaporator test again.

The video recorder determines whether the additional duration is greater than or equal to a first duration threshold. When the extra time length is greater than or equal to the first time length threshold value, it is indicated that the tester fails to complete the target nuclear power test within the specified time, and the target nuclear power test at the time may have problems, so that the video recorder sets the recorded target test video as the test video to be copied, so that an engineer can copy the test video to be copied.

In one embodiment, the video recorder may determine, according to the current test data, a failed-to-execute test procedure and an unexecuted test procedure in the target nuclear power test, and determine, according to the failed-to-execute test procedure and the unexecuted test procedure, an extra time required to complete the target nuclear power test. For example, when the target nuclear power test includes A, B, C three test procedures, and the current test data represents that the test procedure a fails to be executed, the test procedure B succeeds to be executed, and the test procedure C is not executed, the video recorder determines the execution duration required for repeatedly executing the test procedure a and the execution duration required for executing the test procedure C according to the theoretical execution durations corresponding to the test procedures output by the duration estimation model, and superimposes the execution duration required for the test procedure a and the execution duration required for executing the test procedure C to obtain additional duration.

In one embodiment, when the recorded target test video is determined to be a video to be rerecorded, the video recorder automatically sends the test video to the communication terminal of the corresponding engineer, so that the engineer can perform rerecording on the test video in time before the target nuclear power test is not finished, the problem of the preorder test procedure is determined, and the test operation of a tester can be corrected in time before the target nuclear power test is not finished. Wherein, the engineer can be a manager with abundant experimental experience.

In one embodiment, when the extra duration is greater than or equal to the estimated duration, the video recorder sends a preset message to prompt the tester to improve the test efficiency.

In the method for determining the multi-disc test video, the bound test ticket number is obtained when the video recording operation is triggered to start, and the test ticket number can be analyzed to obtain the process information corresponding to each test process; by acquiring the process information corresponding to each test process, the test time required for executing the target nuclear power test can be estimated according to the process information, so that the estimated test time can be obtained; by determining the estimated test time length, the extra time length required for completing the target nuclear power test can be determined according to the current test data of the target nuclear power test when the actual test time length of the nuclear power test reaches the estimated test time length, so that whether the current target nuclear power test is abnormal or not can be judged according to the extra time length and a first preset time length threshold value, and whether the recorded target test video is the test video of the to-be-copied disk or not is determined. Because this application can confirm automatically and treat the test video of reranking, consequently compare in the tradition after the experiment, whether the video of the basis of artifical judgement test is the test video of waiting to rerank, this application has promoted the deterministic efficiency of the video of rerank greatly.

In one embodiment, the estimating the test duration of the target nuclear power test according to the process information corresponding to each test process to obtain the estimated test duration includes: inputting the process information corresponding to each test process into a pre-trained time duration estimation model to obtain the ideal execution time duration corresponding to each test process; determining actual execution time corresponding to each test procedure in a historical nuclear power test; acquiring preset adjustment factors corresponding to each test procedure; calculating the predicted execution time length corresponding to each test procedure by using the ideal execution time length and the actual execution time length according to the adjustment factor; and determining the estimated test duration of the target nuclear power experiment according to the predicted execution duration corresponding to each test procedure.

Specifically, the video recorder acquires a preset duration estimation model, and obtains ideal execution duration corresponding to each test procedure according to procedure information corresponding to each test procedure by using the duration estimation model. When a tester executes a historical nuclear power test, the execution duration of each test procedure can be recorded, so that the video recorder can acquire the actual execution duration corresponding to each test procedure in the historical nuclear power test. The historical nuclear power test and the target nuclear power test have the same test procedures. And the video recorder acquires the adjustment factor corresponding to each test procedure, inputs the adjustment factor, the ideal execution duration and the actual execution duration into a preset adjustment model, and determines the predicted execution duration corresponding to each test procedure. For example, the tuning model may be: the predicted execution duration is the actual execution duration plus the ideal execution duration (1-adjustment factor). And when the predicted execution time length corresponding to each nuclear power test is obtained, the video recorder superposes the predicted execution time lengths to obtain the corresponding predicted test time length.

In the embodiment, the estimated test time length is determined by combining the adjustment factor with the actual execution time length and the ideal execution time length, so that the determined estimated test time length not only comprehensively considers the historical actual condition, but also considers the ideal condition, and the estimated test time length is more accurate.

In one embodiment, the process information includes equipment part keywords corresponding to the process; determining the extra time required for completing the target nuclear power test according to the current test data of the target nuclear power test comprises the following steps:

step S302, intercepting a video clip with a first duration from the current moment from the recorded target test video;

step S304, traversing at least one video frame in the video clip, and identifying the current operating equipment part in each traversed video frame;

step S306, when the current operation equipment part in the traversed video frame belongs to the target equipment part corresponding to the equipment part keyword, determining the traversed video frame as the target video frame;

s308, screening out a target equipment part keyword corresponding to the current operating equipment part in the target video frame from the equipment part keywords corresponding to the test procedures;

step S310, determining the current test procedure being executed based on the key words of the target equipment parts;

step S312, determining the extra time required for completing the target nuclear power test according to the current test data of the current test procedure.

Wherein each test procedure corresponds to at least one target device part. The target equipment part refers to a key part in nuclear power equipment to be tested in a nuclear power test, one nuclear power equipment can comprise a plurality of key parts, each test procedure of the nuclear power test can respectively test the corresponding key part, for example, when the current nuclear power test is to test the A test equipment, the A1 key part in the A test equipment can be tested through the a test procedure, the A2 key part in the A test equipment can be tested through the b test procedure, and when the key part needs to be tested, a tester inevitably needs to operate the key part, so that the current test procedure which is currently executed can be determined based on the current operation equipment part in a video frame. The device part keyword is a keyword for characterizing the target device part, for example, the device part keyword may be a part name of the target device part. The test work order includes device part keywords corresponding to each test process, which is easy to understand.

Specifically, the video recorder intercepts a video segment with a first duration from the current moment from the recorded target test video, that is, the video segment with the first duration is traced back from the current moment after being intercepted. Further, when the video recorder obtains the video clip, a plurality of video frames in the video clip are traversed, and the current operating equipment parts in each traversed video frame are identified. The current operation equipment part refers to the equipment part which is operated by a tester. The video recorder can detect the current operating equipment part in the video frame based on a preset equipment part detection algorithm, so that the equipment part which is operated by a tester is determined. The equipment part detection algorithm can be customized as required, for example, the current operation equipment part can be identified based on an image identification algorithm in matlab, or the current operation equipment part can be identified based on an image identification algorithm in OpenCV.

Further, the video recorder judges whether the current operating equipment part in the currently traversed video frame belongs to a target equipment part corresponding to the target nuclear power test, namely whether the current operating equipment part belongs to a target equipment part corresponding to the equipment part keyword. If the current traversed video frame does not belong to the target video frame, the video recorder suspends the current traversed video frame as the target video frame. The process information includes the equipment part key words corresponding to the processes, so that the video recorder can synthesize the process information of each test process to obtain the equipment part key words corresponding to each test process. The video recorder screens out a target equipment part keyword corresponding to the current operating equipment part in the target video frame from the equipment part keywords corresponding to the test procedures, and determines the current test procedure being executed based on the target equipment part keyword. For example, when the key device parts corresponding to the test procedure 1 are a and B, the key device parts corresponding to the test procedure 2 are C and D, the current operating device part in the target video frame 1 is a, and the current operating device part in the target video frame 2 is B, the target key device parts corresponding to the target video frame are a and B, and the terminal takes the test procedure 1 as the current test procedure.

Further, when the current test procedure is determined, the video recorder can obtain current test data corresponding to the current test procedure, and determine the extra duration according to the current test data. For example, when the current test data indicates that the current test procedure is performed by half, the video recorder determines the extra duration according to the ideal execution duration and/or half of the predicted execution duration required for performing the current test procedure, and the ideal execution duration and/or predicted execution duration required for remaining unexecuted procedures. For another example, when the current test data indicates that the current test procedure fails to be executed, the video recorder determines whether the current test procedure has a relevant test procedure according to the procedure information, if the current test procedure has the relevant test procedure, the video recorder determines the ideal execution duration/or the predicted execution duration required by the current test procedure, the relevant test procedure and the unexecuted test procedure, the relevant test procedure is overlapped, and the video recorder determines the ideal execution duration/or the predicted execution duration required by the current test procedure, the relevant test procedure and the unexecuted test procedure to obtain the extra duration.

In one embodiment, when the matching is unsuccessful, the duration of the test video recorded for the test procedure of the target nuclear power test within the first duration may be considered too short, the video recorder may increase the first duration, and based on the increased first duration, the video clip may be re-acquired.

In the above embodiment, the extra time length is determined by combining the current test data of the current test procedure, so that the determined extra time length is more accurate.

In one embodiment, traversing at least one video frame in a video clip and identifying a currently operating equipment part in each video frame traversed comprises: traversing at least one video frame in the video clip; performing hand detection on the video frames in the current traversal sequence, and cutting out an equipment part image which is in contact with a hand region from the video frames in the current traversal sequence based on the detection result of the hand detection; and identifying the equipment part image to obtain the current operation equipment part in the video frame of the current traversal sequence.

Specifically, the video recorder traverses at least one video frame in the video clip, and performs hand detection on the video frames in the current traversal order based on a preset hand detection algorithm. When the hand regions in the video frames of the current traversal sequence are determined through a hand detection algorithm, the video recorder selects image regions in contact with the hand regions through the geometric frames of the preset size, namely, the device part images in contact with the hand regions are cut out based on the geometric frames of the preset size. And the video recorder inputs the cut equipment part images into a pre-trained equipment part recognition model, and the equipment part images are recognized through the pre-trained equipment part recognition model to obtain the current operation equipment parts shown in the figure 4 in the video frame of the current traversal sequence. It is worth noting that the geometric size of the preset geometric box can be freely scaled according to the hand detection result. FIG. 4 is a schematic view of the current operating equipment components in one embodiment.

In another embodiment, when the device part recognition model fails to recognize the currently operating device part in the device part image, the video recorder enlarges the size of the geometric frame according to a preset size enlargement rule, for example, enlarges the geometric frame with a preset size by one time, so that the enlarged geometric frame can be framed and selected to obtain a device part image with a larger size, and then the pre-trained device part recognition model can extract richer device part features from the device part image with a larger size, and determine the currently operating device part according to the richer device part features.

In another embodiment, when the device part recognition model recognizes that a plurality of device parts exist in the device part image, the size of the geometric frame is reduced by a preset size reduction rule of the video recorder, and the geometric frame with the preset size is reduced by one time, so that the reduced geometric frame can frame the device part image which is more accurately contacted with the hand, and the pre-trained device part recognition model can accurately recognize a current operation device part.

In the above embodiment, since the tester inevitably contacts a certain device part in the testing device by a hand during the testing process, the device part currently operated by the tester can be determined based on the hand detection result by performing the hand detection on the video frame.

In an embodiment, the method for determining a double-disc test video further includes: when video recording is finished within the estimated test time length since the video recording operation is started by triggering, determining the actual test time length of the target nuclear power test according to the starting time of the video recording and the finishing time of the video recording; and when the time difference between the actual test time length and the estimated test time length is greater than or equal to a second preset time length threshold value, setting the target test video as the test video to be copied.

Specifically, when a tester triggers a video recording ending operation through a video recorder within the estimated test duration, that is, when the video recording ends within the estimated test duration since the video recording operation is started, the video recorder indicates that the tester completes a target nuclear power test within the estimated test duration, and at the moment, the video recorder determines the actual test duration of the target nuclear power test according to the starting time of the video recording and the ending time of the video recording, and determines the time difference between the actual test duration and the estimated test duration. When the time difference between the actual test time length and the estimated test time length is larger than or equal to a second preset time length threshold value, the target nuclear power test completed by the tester too quickly is indicated, and at the moment, the nuclear power test process may have problems, so that the video recorder sets the recorded target test video as the test video to be copied.

In this embodiment, whether the recorded target nuclear power test is a to-be-copied disk test video is judged by taking the estimated test duration as a reference, so that the determined to-be-copied disk test video is more accurate.

In an embodiment, the method for determining a double-disc test video further includes: when the video uploading operation is not triggered within a second time period since the video recording operation is finished by triggering, determining the corresponding personnel identification of the target test according to the bound test ticket number; determining a corresponding communication identifier according to the personnel identifier; and sending the preset video uploading prompt information to the communication terminal corresponding to the communication identifier.

Specifically, the video recorder judges whether the video uploading operation is triggered by the tester within the second time period since the video recording operation is triggered to end, that is, the video recorder judges whether the tester uploads the target test video to the preset server within the specified time period since the video recording operation is ended. If the target test video is not uploaded to the preset server within the second time period, the video recorder analyzes the bound test ticket number to obtain a personnel identifier of a target real test personnel executing the target nuclear power test, and determines a corresponding communication identifier according to the determined personnel identifier, namely determines the communication identifier corresponding to the target test personnel according to the personnel identifier, so that the video recorder can send the preset video uploading prompt information to the communication terminal corresponding to the communication identifier.

In this embodiment, the video uploading prompt information is correspondingly sent, so that the tester can be prompted to upload the target test video to the preset server as soon as possible, and the server can comprehensively manage the target test video.
