Description

Technical Field

[0001] The present invention relates to the technical field of practical operation examination scoring, and in particular, to a shield tunneling machine simulation practical operation examination scoring method and system, electronic equipment, and a computer-readable storage medium. Background Art

[0002] In recent years, there are more and more tunnel projects, and shield construction is widely used in the tunnel industry. Due to the complex structure of shield equipment and complex geological conditions, shield drivers must undergo professional training before taking up their posts, and shield tunneling machine simulation training systems have also been applied. The shield tunneling machine simulation training system allows trainers to simulate the construction site to train and test shield drivers without entering the construction site. The shield tunneling machine simulation training test is mainly a practical test, which has the following characteristics compared to conventional practical tests: 1. The test questions are completed in multiple steps, and the operation steps have a sequence; 2. The same step in the question may appear multiple times, and the corresponding parameters are different each time; 3. During the practical test, candidates may have irrelevant operations and may have to answer questions from a certain step again after discovering an operation error; therefore, how to quickly and accurately score the shield tunneling machine simulation practical test is a technical problem in this field.

[0003] Conventional shield tunneling machine simulation training test scoring methods usually adopt manual scoring. For example, patent CN105513451B discloses a shield tunneling machine simulation training system, and examiners conduct on-site inspections and scoring through examiner evaluation stations. However, this manual scoring method is time-consuming and labor-intensive, has low efficiency, and the scoring results are greatly affected by the examiner's subjective judgment, making it difficult to ensure the accuracy and fairness of the scoring. In addition, there are also some practical test scoring methods that compare the operation steps with the corresponding scoring items in order, and calculate the test results based on the comparison results. For example, patent CN110634346B discloses a gas operation training assessment method, which collects the signals of the detection devices of each assessment unit during the candidate's operation, compares the operation steps with the corresponding scoring items in order, and calculates the candidate's score based on the comparison results. However, this scoring method uses the order of operating steps as the basic scoring rule, and examines the consistency and rationality of the operating steps. In the shield tunneling machine simulation training test, candidates often make irrelevant operations when answering questions, and have to start from a certain step again after discovering an operating error. Therefore, this scoring method will have the problem of inaccurate scoring when scoring the shield tunneling machine simulation training test. Summary of the invention

[0004] The present invention provides a shield tunneling machine simulation practical operation test scoring method and system, electronic equipment, and computer-readable storage medium, which can accurately score the examinee when he / she has irrelevant operations in answering questions or discovers an operation error and then starts to answer questions again from a certain step, without the need for human intervention, thereby improving scoring efficiency.

[0005] According to one aspect of the present invention, a shield tunneling machine simulation practical operation test scoring method is provided, comprising the following contents:

[0006] Get the current test questions and answers;

[0007] Classify all scoring items in the answer to obtain multiple scoring item categories;

[0008] Collect the operation records of the examinees answering questions and record the operation time to obtain the operation record sequence;

[0009] The operation record sequence is grouped according to the type of scoring item, and invalid operation records are eliminated to obtain the operation record grouping sequence;

[0010] Traverse the operation record grouping sequence according to the scoring items in the answer order to obtain multiple answer sequences;

[0011] Each answer sequence is scored and the highest score is selected as the candidate's score.

[0012] Furthermore, the process of scoring each answer sequence includes the following:

[0013] The order of operation records in each answer sequence is determined according to the operation time, and then the score of each operation record is determined according to the scoring criteria of the scoring item. The scores of all operation records are added together to obtain the score of the answer sequence.

[0014] Furthermore, if the scoring criteria for a certain scoring item have no order requirements, points can be obtained as long as there are corresponding operation records; if the scoring criteria for a certain scoring item have order requirements, the operation records must meet the operation order requirements to obtain points; if the scoring criteria for a certain scoring item also include parameter setting ranges, the parameters in the operation records must also meet the requirements to obtain points.

[0015] Furthermore, the process of traversing the operation record grouping sequence according to the scoring items in the answer to obtain multiple answer sequences includes the following:

[0016] According to the order of the scoring items in the answer, the operation records for the answer question content are selected in the operation record grouping sequence and combined to generate a complete answer sequence. If there are multiple operation records for the same answer content, an answer sequence is generated for each operation record.

[0017] Furthermore, if there is no operation record for a certain scoring item corresponding to the answer question content, the operation record corresponding to the scoring item in the answer sequence is set to empty.

[0018] Furthermore, after collecting the operation records of the candidates' answers and recording the operation time, if there are multiple operation records corresponding to the same answer content, it is determined whether the time difference between the multiple operation records is less than a threshold. If it is less than the threshold, the redundant operation records and their operation time are eliminated, and only one operation record and its operation time are retained.

[0019] In addition, the present invention also provides a shield tunneling machine simulation practical operation test scoring system, comprising:

[0020] The test question and answer acquisition module is used to obtain the current test question and answer;

[0021] A rating item classification module is used to classify all rating items in the answer to obtain multiple rating item categories;

[0022] An operation record collection module is used to collect the operation records of the examinees' answers and record the operation time to obtain an operation record sequence;

[0023] An operation record grouping module is used to group the operation record sequence according to the type of scoring item and remove invalid operation records to obtain an operation record grouping sequence;

[0024] An answer sequence generation module is used to traverse the operation record grouping sequence according to the scoring items in the answer sequence to obtain multiple answer sequences;

[0025] The candidate score scoring module is used to score each answer sequence and select the highest score as the candidate score.

[0026] Furthermore, the operation record collection module is also used to deduplicate the operation records after collecting the operation records of the examinees' answers and recording the operation time. If there are multiple operation records corresponding to the same answer content, it is determined whether the time difference between the multiple operation records is less than a threshold. If it is less than the threshold, redundant operation records and their operation times are eliminated, and only one operation record and its operation time are retained.

[0027] In addition, the present invention also provides an electronic device, including a processor and a memory, wherein the memory stores a computer program, and the processor executes the steps of the above method by calling the computer program stored in the memory.

[0028] In addition, the present invention also provides a computer-readable storage medium for storing a computer program for scoring a shield tunneling machine simulation practical examination, and the computer program executes the steps of the method described above when running on a computer.

[0029] The present invention has the following beneficial effects:

[0030] The shield tunneling machine simulation practical test scoring method of the present invention classifies all scoring items in the answer to obtain multiple scoring item types, then groups the operation record sequence according to the scoring item type, and traverses the operation record grouping sequence according to the scoring item order to generate multiple answer sequences, so that the operation records of the examinee's answers are grouped, arranged, and combined to form multiple answer sequences, and redundant operations are accurately eliminated. Even if irrelevant operations occur when the examinee answers the questions or the examinee finds an operation error and then answers the question again from a certain step, the examinee's answer results can still be accurately scored, and instant scoring can be achieved after each question is completed, without human intervention, thereby improving scoring efficiency.

[0031] In addition, the shield tunneling machine simulation practical operation test scoring system of the present invention also has the above advantages.

[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] Reference Figure 1 The preferred embodiment of the present application provides a shield tunneling machine simulation practical test scoring method, including the following contents:

[0044] Step S1: Get the current test questions and answers;

[0045] Step S2: classify all scoring items in the answer to obtain multiple scoring item categories;

[0046] Step S3: Collect the operation records of the examinee's answers and record the operation time to obtain an operation record sequence;

[0047] Step S4: grouping the operation record sequence according to the type of scoring item, and removing invalid operation records to obtain an operation record grouping sequence;

[0048] Step S5: traverse the operation record grouping sequence according to the scoring items in the answer to obtain multiple answer sequences;

[0049] Step S6: Score each answer sequence and select the highest score as the candidate's score.

[0050] It can be understood that the shield tunneling machine simulation practical test scoring method of this embodiment, after obtaining the current test question and answer, first classifies all the scoring items in the answer to obtain multiple scoring item types; then after collecting the operation record sequence, the operation record sequence is grouped according to the scoring item type, and invalid operation records are eliminated to obtain the operation record grouping sequence; then, the operation record grouping sequence is traversed according to the scoring item order to generate multiple answer sequences; finally, each answer sequence is scored, and the highest score is selected as the candidate's score. Therefore, the shield tunneling machine simulation practical test scoring method of the present invention, by classifying all the scoring items in the answer to obtain multiple scoring item types, then grouping the operation record sequence according to the scoring item type, and traversing the operation record grouping sequence according to the scoring item order to generate multiple answer sequences, so that the operation records of the candidate's answer form multiple answer sequences in a grouping, arrangement, and combination manner, accurately eliminating redundant operations, even if the candidate has irrelevant operations when answering the question or finds an operation error and then answers the question again from a certain step, the candidate's answer score can still be accurately scored, and each question can be scored immediately after the test is completed, without human intervention, thereby improving the scoring efficiency.

[0051] It can be understood that in step S1, the current test questions and answers of the examinee are obtained from the shield tunneling machine simulation practical test system. For example, in one embodiment of the present invention, the current test questions and answers of the examinee are as follows: Figure 2 As shown, the test question is: start the cutterhead, the cutterhead rotates forward, starts at a low speed of 0.5r / min~1r / min, and finally runs stably at 3r / min. That is, the examinee needs to perform simulation operations on the shield tunneling machine simulation practical test system to start the cutterhead of the shield tunneling machine at a speed of 0.5r / min~1r / min, and make the cutterhead rotate forward, and finally control the cutterhead to run stably at a speed of 3r / min; and the answer to this test question includes eight operating steps, each of which is scored 1 point, which are switching to the cutterhead interface, starting the water pump, starting the gear oil, setting the cutterhead speed to 0.5r / min~1r / min, selecting gear 1, switching the cutterhead rotation direction to forward, starting the motor and setting the cutterhead speed to 3r / min.

[0052] It can be understood that in step S2, the answer includes multiple scoring items, some of which have the same answer content and may appear multiple times, but the corresponding parameters are different each time. For example, Figure 2 The scoring item - cutter speed setting appears twice, but the speeds are different. Therefore, the present invention first classifies all scoring items, removes duplicate scoring items, and obtains multiple scoring item types, for example, Figure 2 After the answers in the answer are classified into rating items, the types of rating items obtained are as follows Figure 3 shown.

[0053] It can be understood that in step S3, the operation records of the examinee operating all the test units in the shield tunneling machine simulation practical test system are collected, and the operation time corresponding to each operation record is recorded to obtain an operation record sequence. For example, in one embodiment of the present invention, the collected operation record sequence is as follows: Figure 4 shown.

[0054] Optionally, in step S3, after collecting the operation records of the examinee's answers and recording the operation time, if there are multiple operation records corresponding to the same answer content, it is determined whether the time difference between the multiple operation records is less than a threshold, for example, less than 5s. If it is less than the threshold, it is considered that the examinee has made an erroneous operation or repeated operation in a short period of time. In this case, redundant operation records and their operation time are eliminated, and only one operation record and its operation time are retained to reduce the number of subsequent operation record permutations and combinations, thereby reducing the amount of calculation, which is conducive to improving scoring efficiency.

[0055] It can be understood that in step S4, the operation record sequence collected in step S3 is grouped according to the scoring item types obtained by classification in step S2, and invalid operation records are removed, wherein invalid operation records refer to operation records that are not included in the scoring item types, thereby obtaining an operation record grouping sequence. Figure 3 The rating item types in Figure 4 After grouping the operation record sequence collected in , and removing invalid operation records, the obtained operation record grouping sequence is as follows Figure 5 shown.

[0056] It can be understood that in step S5, the operation record grouping sequence is traversed according to the scoring items in the answer, so that the operation records of the examinee's answer are grouped, arranged, and combined to form multiple answer sequences. The process of traversing the operation record grouping sequence according to the scoring items in the answer to obtain multiple answer sequences includes the following:

[0057] According to the order of the scoring items in the answer, the operation records for the answer question content are selected in the operation record grouping sequence and combined to generate a complete answer sequence. If there are multiple operation records for the same answer content, an answer sequence is generated for each operation record.

[0058] Specifically, for Figure 5 The operation records in the grouping sequence are based on Figure 2 The order of scoring items for the answers is Figure 5In the answer question, select and combine the operation records of the answer question content in turn to generate a complete answer sequence as the scoring sequence. Among them, if there are multiple operation records for the same answer question content, each operation record will generate an answer sequence. For example, if the answer question content "starting gear oil" corresponds to two operation records (with different operation times), two answer sequences will be generated; or, if the answer question content "knife head speed setting" corresponds to three operation records, three answer sequences will be generated. Finally, the multiple scoring sequences obtained are as follows Figure 6 shown.

[0059] In addition, if there is no operation record for a certain scoring item corresponding to the answer question content, the operation record corresponding to the scoring item in the answer sequence is set to empty.

[0060] It can be understood that in step S6, for the multiple answer sequences obtained in step S5, i.e., the scoring sequences, each answer sequence is scored, and the highest score is selected as the candidate's score. The process of scoring each answer sequence includes the following:

[0061] The order of operation records in each answer sequence is determined based on the operation time, and then the score of each operation record is determined based on the scoring criteria of the scoring item, and the scores of all operation records are added together to obtain the score of the answer sequence. Among them, in the scoring criteria of the scoring items, if the scoring criteria of a scoring item do not have a sequence requirement, the corresponding operation record can be scored; if the scoring criteria of a scoring item have a sequence requirement, the operation record must meet the operation sequence requirement to score, and if the operation sequence does not meet the requirement, no score will be scored; if the scoring criteria of a scoring item also includes a parameter setting range, the parameters in the operation record must also meet the requirement to score.

[0062] For example, for Figure 6 When scoring the scoring sequence n in , the scoring result is as follows Figure 7 As shown, the details are as follows:

[0063] 1) Switch to the knife disk interface, answer the questions in the required content and order, and get 1 point;

[0064] 2) Press the "Start Water Pump" button. If the answer content and order meet the requirements, you will get 1 point;

[0065] 3) Press the "Gear Oil Start" button. If the answer content and order meet the requirements, you will get 1 point;

[0066] 4) The cutter speed is set to 0.8r / min, which meets the parameter setting range of 0.5-1r / min, and the sequence meets the requirements, and 1 point is awarded;

[0067] 5) If the gear switch is turned to gear 1 and the answer content and order meet the requirements, 1 point will be awarded;

[0068] 6) The direction of rotation of the cutter head is switched to forward rotation. The answer content meets the requirements, but the answer order is not satisfied, and 0 points are awarded;

[0069] 7) Press the "Start Motor" button. If the answer content and order meet the requirements, you will get 1 point;

[0070] 8) The cutter speed is set to 3r / min, which meets the 3r / min parameter setting requirements, and the order meets the requirements, and 1 point is awarded;

[0071] 9) Calculate the sequence score. The answer sequence score is 7 points.

[0072] It can be understood that the present invention forms multiple answer sequences by grouping, arranging and combining the operation records of the examinees' answers, and then scores each answer sequence. This method is compatible with the scoring of sequential practical examinations and the scoring of non-sequential practical examinations, thereby improving the applicability of the scoring algorithm.

[0073] like Figure 8 As shown, another embodiment of the present invention further provides a shield tunneling machine simulation practical operation test scoring system, preferably using the shield tunneling machine simulation practical operation test scoring method as described above, the system comprising:

[0074] The test question and answer acquisition module is used to obtain the current test question and answer;

[0075] A rating item classification module is used to classify all rating items in the answer to obtain multiple rating item categories;

[0076] An operation record collection module is used to collect the operation records of the examinees' answers and record the operation time to obtain an operation record sequence;

[0077] An operation record grouping module is used to group the operation record sequence according to the type of scoring item and remove invalid operation records to obtain an operation record grouping sequence;

[0078] An answer sequence generation module is used to traverse the operation record grouping sequence according to the scoring items in the answer sequence to obtain multiple answer sequences;

[0079] The candidate score scoring module is used to score each answer sequence and select the highest score as the candidate score.

[0080] It can be understood that the shield tunneling machine simulation practical test scoring system of this embodiment, after obtaining the current test question and answer, first classifies all the scoring items in the answer to obtain multiple scoring item types; then after collecting the operation record sequence, the operation record sequence is grouped according to the scoring item type, and invalid operation records are eliminated to obtain the operation record grouping sequence; then, the operation record grouping sequence is traversed according to the scoring item order to generate multiple answer sequences; finally, each answer sequence is scored, and the highest score is selected as the candidate's score. Therefore, the shield tunneling machine simulation practical test scoring system of the present invention, by classifying all the scoring items in the answer to obtain multiple scoring item types, then grouping the operation record sequence according to the scoring item type, and traversing the operation record grouping sequence according to the scoring item order to generate multiple answer sequences, so that the operation records of the candidate's answer form multiple answer sequences in a grouping, arrangement, and combination manner, accurately eliminating redundant operations, even if the candidate has irrelevant operations when answering the question or finds an operation error and then answers the question again from a certain step, the candidate's answer score can still be accurately scored, and instant scoring can be achieved after each question is completed, without human intervention, thereby improving scoring efficiency.

[0081] In addition, the operation record collection module is also used to deduplicate the operation records after collecting the operation records of the examinees' answers and recording the operation time. If there are multiple operation records corresponding to the same answer content, it is determined whether the time difference between the multiple operation records is less than a threshold. If it is less than the threshold, the redundant operation records and their operation time are eliminated, and only one operation record and its operation time are retained.
