Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Aiming at the situation that a time acquisition process of a basic action unit operated by a digital man-machine interface of a nuclear power station does not exist at present, the time acquisition method of the basic action unit operated by the digital man-machine interface of the nuclear power station is constructed.
First, conventional human factor data collection relies on a model that determines a raw data collection mode and a data analysis mode. This brings about the following problems: different human factor analysis models require different data acquisition modes, and data acquired based on a certain special model cannot be used for other models. It is more difficult to obtain the denominator (i.e. the total number of movements) of a basic movement unit when determining the failure rate according to the conventional probability determination thinking, so that it is difficult to obtain failure rate data based on actual statistical data. In order to ensure the accuracy, consistency, practicability and applicability of the acquired data, the limitations of a specific human factor analysis model and the traditional error rate acquisition thinking should be eliminated. The problem can be solved to a certain extent by adopting a relational data description mode, and therefore, the establishment of a structured data acquisition mode and general statistical data is very necessary.
The digital full-range simulator simulates the whole operation process of the nuclear power station by using a set of computer software, can simulate accident situations and operator responses under different conditions, covers working conditions of normal operation, abnormal transient state, accident operation and the like of the power station, and can provide objective basis for time data acquisition of basic action units of an operator. Meanwhile, the operation process of an operator based on the digital analog machine is natural, and additional intervention measures or pressure are not needed to influence the task execution process, so that the situation is closer to the real situation. The data collected by the simulator is similar to the data under actual power plant conditions, and is one of the main means for collecting operation task data at present.
Based on this, this application simulates scene and the operator response under the different accident conditions of power plant through the digital full range analog machine of nuclear power station, and the time data of collection personnel's operation provides the basis for personnel's action objective research under the accident condition. The statistical analysis of the acquisition results proves that the data of the digital full-range analog machine can be used as the acquisition basis of the basic action time of the digital operation, and the digital full-range analog machine has rationality and feasibility.
Fig. 1 is a flowchart of a first embodiment of a time acquisition method for a digital operation basic action unit of a nuclear power plant, and the time acquisition method of the embodiment includes the following steps:
s10, calling a pre-established accident test scene library;
s20, when a plurality of groups of operators sequentially execute the digital operation of the selected event testing situation response work on the digital full-range analog machine according to the operation rules, acquiring screen recording information of a display interface of the digital full-range analog machine and acquiring on-site audio and video information to acquire screen recording information;
s30, calling a comparison library of a predetermined basic action unit type and an operation diagram type and a running rule path library corresponding to the selected accident test scene, and analyzing the screen recording and video recording information to acquire the operation time of each operator for implementing each basic action unit;
s40, calling a preset equipment response time library, and respectively determining a plurality of implementation times of each basic action unit according to the operation time of each basic action unit and the corresponding equipment response time in the equipment response time library;
and S50, respectively carrying out statistical processing on a plurality of implementation times of each basic action unit to obtain an implementation time statistical average value of each basic action unit and outputting the implementation time statistical average value. With respect to this embodiment, it is to be noted that:
in step S10, an accident test scenario library needs to be established on the time acquisition system in advance, and specifically, the nuclear power station accident condition range is determined according to the design condition list; and establishing an accident test scenario library according to the accident model and a timing chart thereof given by the certainty factor security analysis and PSA (pressure sensitive Association) file. Selecting a running procedure path corresponding to each accident in a State-Oriented procedure (SOP) procedure to generate a running procedure path library corresponding to each accident test scenario. Based on the selected operation rule path, selecting the basic action unit type of the digital man-machine interface operation in the SOP, giving an operation instruction if necessary, so as to define the meaning of the basic action unit and the time acquisition start and end requirements, and generating a basic action unit type library of the digital operation, as shown in table 1. The method for selecting the basic action unit type of the digital operation based on the SOP protocol can solve the problem that the acquisition object exists from scratch.
TABLE 1
Then, it is determined that the selected digital operation basic action unit type corresponds to the operation chart sheet type on the digital human-computer interface, and a comparison library of the basic action unit type and the operation chart sheet type is generated, as shown in table 2. In addition, if necessary, manipulation instructions and requests are made in a manner that is customary for the operator for more complicated adjustment operations.
TABLE 2
And then, setting an accident test scene library on the digital nuclear power station full-range simulator according to the purpose, range and content of the digital full-range simulator test defined in the accident test scene library and the working condition requirement for executing the test.
Finally, it should be noted that the predetermined accident test scenario library, the comparison library of the types of the basic action units and the operation diagram amplitude types, the operation rule path library corresponding to each accident test scenario, and the later-mentioned device response time library, the basic action unit theoretical time library, the basic action unit operation time limit library, the operator information library, the task information library, and the like, together form a complete information acquisition system, which facilitates the call of the subsequent time acquisition process.
With respect to step S20, after setting up the accident testing scenario on the digital full-scope simulation machine, a plurality of operators of the licensed and experienced operation team can be arranged to perform the selected (randomly selected or sequentially selected) accident testing scenario on the digital full-scope simulation machine platform according to the regular training operation. And before the digital operation is executed, operator information and task information can be input, and the operator information data and the task information data are the premise and the basis for ensuring the time data acquisition quality. The entered operator information is stored in an operator information base, and the entered task information is stored in a task information base. The statistical tables of the operator information and the task information are shown in tables 3 and 4, respectively.
TABLE 3
TABLE 4
When an operator executes digital operation, the camera and special software on the digital full-range simulator implement real-time video recording, screen recording, sound recording and other operations, and record a complete test process so as to collect screen recording and video recording information. The operation steps are recorded into a form to form an operation procedure path library, and each step automatically calls the type of the basic action unit. Therefore, after an operator tests on the digital full-range simulator, the operation time can be determined from the screen recording and video recording information by calling the operation rule path library. The method solves the problems of authenticity, effectiveness and usability of data acquisition work, improvement of credibility of quantitative evaluation prediction and sample amount statistics through the real scene simulation of a full-range digital full-range simulator and a holding operator, and acquires video/audio data executed by a digital rule by using the technical development advantages of the digital full-range simulator and a computer means, thereby solving the objectivity and accuracy of time data acquisition. In addition, the experimental process can be observed and recorded through an audio-video monitoring interface and/or one-way visual glass, so that the experimental process is prevented from being interfered.
In step S30, the acquired video recording information is analyzed by calling a comparison library of the basic action unit type and the operation diagram type to acquire the operation time of each operator when the basic action unit is executed. In addition, in order to avoid the inconsistency of formats or contents caused by observation and data collection of different persons or different stages, preprocessing can be performed by an excel data screening tool and the like, and partial data records are shown in a table 5. The data in the two-dimensional table format is conveniently imported into various types of common databases, and statistical analysis can be performed on the data through the databases or the data can be used as basic data to provide analysis for other researches. The data collection result and the mathematical analysis result show that the information to be collected can be accurately, reliably and comprehensively obtained by the method, and the results have good consistency.
TABLE 5
Regarding step S40, it should be noted that, according to the actually measured device response data of the nuclear power plant commissioning test, a response time list of the entity device corresponding to the operation needs to be given in advance, as shown in table 6, and a device response time library is generated. It should be understood that not all basic action units correspond to device response times, only basic action units of an operation class correspond to device response times. When the implementation time of each basic action unit of each operator is determined, the implementation time of the basic action unit can be determined by superposing the corresponding operation time and the corresponding equipment response time of the basic action unit of the operation class; and directly taking the corresponding operation time of the basic action unit of the non-operation class as the implementation time of the basic action unit. Therefore, the time data acquired through the test of the digital full-range analog machine can be corrected based on the response time data of the nuclear power station debugging actual measurement equipment, and the integrity of time data acquisition is improved.
TABLE 6
With respect to step S50, it should be noted that, based on Microsoft writing a data analysis processing program, for each basic action unit, a lognormal distribution is used to perform statistics and variance tests on a plurality of collected implementation times to obtain a statistical mean of the implementation times of the corresponding basic action unit, and a table of implementation time mean values of the basic action units is output, as shown in table 7.
TABLE 7
According to the technical scheme of the embodiment, when an operator carries out digital operation of accident situation response work on a digital full-range simulator of the nuclear power station, real-time screen recording and field audio and video acquisition are carried out on a display interface of the digital full-range simulator, the screen recording and video recording information is analyzed to obtain the operation time of each operator for implementing each basic action unit, and the implementation time of each basic action unit is determined through a calling equipment response time base. Finally, for each basic action unit, the statistical processing is carried out on the acquired implementation time to obtain the implementation time statistical mean value of the corresponding basic action unit, so that the acquisition of the time data of the basic action unit operated by the digital man-machine interface can be systematically, objectively and reproducibly realized. The acquired time data can be further applied to newly building and modifying nuclear power stations and become one of theoretical bases of related digital man-machine interface design, personnel task analysis, personnel reliability evaluation and team performance evaluation work. Moreover, as the operator trains based on the digital rule and the digital man-machine interface of the digital full-range analog machine daily, the personnel quality is better, and the operation technology is skilled, the obtained result is better in applicability than the existing data, and the reliability of the evaluation result based on the data is higher.
Further, in an optional embodiment, after step S50, the method further includes:
and S60, storing the implementation time statistical mean value of each basic action unit into a basic action implementation time base, which is also an autonomous development database for the design and use of the domestic nuclear power station for the first time.
Further, in an optional embodiment, after step S20, the method further includes:
and S70, judging whether the response process of the corresponding accident test scene is abnormal or not according to the screen recording and video recording information, and/or judging whether the operation action process of the corresponding operator is invalid or abnormal or not, and if so, outputting prompt information.
In the embodiment, the accident situation test result on the digital full-range simulator is analyzed to check the conformity of the accident process, for example, the complete accident response process exceeds the accident available time required by the thermal hydraulic power, and the accident situation response process can be considered to be invalid; operator action failures or exceptions, operations that violate operating specifications, operations that violate program execution specifications, temporary suspension operations, etc., may be considered an operational action process exception. By checking the monitoring records, abnormal accident situations, abnormal personnel behaviors or singular data can be eliminated.
Further, in an optional embodiment, after step S30, the method further includes:
step S80, calling a basic action unit theoretical time base, and judging whether the acquired operation time of each basic action unit needs to be revised by comparing the theoretical time of each basic action unit with the operation time of the corresponding basic action unit acquired in step S30.
In this embodiment, the theoretical time of each basic action unit can be calculated according to the basic action unit theoretical time library. And then, whether the acquired statistical mean value of the implementation time of each basic action unit needs to be revised is judged by comparing whether the deviation between the theoretical time and the operation time of each basic action unit is in a specified range, and specifically, if the deviation is more than 30% of the theoretical time, a prompt that the correction is needed is given.
