Description

Technical Field

[0001] The present invention relates to the technical field of elevator repairman examination, and in particular to an automatic evaluation system for elevator repairman practical examination and a method for using the system. Background Art

[0002] Elevator repair personnel (project code T) are one of the special equipment operators specified by the State Administration for Market Regulation. Any operator engaged in elevator repair and maintenance must obtain the "Special Equipment Safety Management and Operator" certificate before they can engage in related elevator operations.

[0003] As a vertical transportation tool, elevators are special equipment used to transport people and goods between different floors of a building or between different floors. Elevators are large in number and widespread in use. They are an integral part of modern urban infrastructure and play an important role in daily life and work. To ensure the safety and reliability of elevators, it is particularly important to provide reliable maintenance and repair personnel for elevators. Therefore, the skill level of elevator operators determines the safety level of the elevators they maintain to a certain extent.

[0004] It is very important to identify whether the candidates meet the requirements of TSG Z6001-2019 "Special Equipment Operator Assessment Rules". The traditional elevator operator assessment adopts a manual scoring mode, paper test papers and oral questions and answers. The task of grading is heavy and the subjective influence of the examiners is large. In particular, the file management requires three years to be traced back. Over a long period of time, the test papers take up a lot of space and are not easy to preserve. When tracing back major accidents, it is difficult to find them. Therefore, the defects are very obvious. It is no longer adapted to the requirements of digitalization and intelligence in modern society, and it is also not conducive to the social expectations of fair and just services for candidates. Summary of the invention

[0005] The purpose of the present invention is to improve the intelligence level of practical examinations for elevator repair workers, to realize functions such as identity authentication, automatic examination evaluation, electronic archives, automatic video recording and playback of the entire examination process, automatic statistics and analysis of factors affecting the examination level of candidates, to guide relevant training institutions in the direction of effective training in the future, and to reduce possible risks in the future work of professional qualification personnel.

One side of the car door lock switch 15 and the other side of the mirror door lock switch 16 are respectively provided with a second detection point 14 and a third detection point 17;

[0010] When taking the theory part of the practical test, the identity verification device 3 obtains the candidate information and compares it with the candidate information stored in the electronic file 12 built into the industrial control machine 4. If it is correct, the industrial control machine 4 randomly selects the theoretical part that should be known from the built-in question database 8 to form a theoretical test paper, and the industrial control machine 4 transmits the test paper to the display 1 for display. The candidate answers the theoretical test questions through the human-computer interaction device 2, and the management and evaluation system generates a theoretical test score sheet;

[0011] During the practical part of the practical test, after verifying that the examinee information is correct, the industrial control machine 4 randomly selects multiple test questions from the practical part question bank built into the question database 8 to form a practical test paper, and the industrial control machine 4 transmits the test paper to the display 1 for display;

[0012] The question database 8 transmits data to the management and evaluation system 7 through the industrial control machine 4, and then is connected to the elevator mirror device 11 through the industrial control machine 4. The elevator mirror device 11 controls the corresponding mirror sub-control 13 according to the practical test paper to respectively manufacture abnormal elevator components, thereby making the corresponding elevator components in the practical test paper in the elevator device 10 fail and cause a fault;

[0013] The examinee observes the fault phenomenon of the failure of the elevator component, detects the voltage value or the resistance value or the current value at the two ends of the second detection point 14 and the third detection point 17, thereby quickly confirming the fault, interacting with the human-machine interaction device 2, and transmitting it to the management and evaluation system 7, which performs the practical test evaluation according to the evaluation rules to obtain the practical test score sheet;

[0014] When the management and evaluation system 7 detects that the same examinee has both a theoretical examination transcript and a practical examination transcript, a comprehensive electronic transcript is generated according to a preset weight;

[0015] The electronic file 12 saves the theoretical test papers, practical test papers and completed theoretical and practical test papers corresponding to the examinees from the question setting database 8, saves the operations of the practical examinees' maintenance process, saves the theoretical test transcripts and / or practical test transcripts and comprehensive electronic transcripts from the management and evaluation system 7, and saves the audio and video recordings of the examinees' process through the hard disk recorder NVR5 and the camera 6.

[0017] The industrial control machine 4 obtains the examinee information and downloads it into a built-in electronic file;

[0018] The identity verification device 3 obtains the examinee information and transmits it to the industrial control machine 4, and compares it with the examinee information stored in the built-in electronic file. If it is correct, the industrial control machine 4 randomly selects theoretical test papers and / or practical test papers from the question database 8, and the industrial control machine 4 transmits the theoretical test papers and / or practical test papers to the display 1 for display. The examinee takes the theoretical test and / or answers the practical questions through the human-computer interaction device 2, and the management and evaluation system generates a theoretical test score sheet and / or a practical test score sheet according to the preset evaluation rules;

[0019] If it fails, the industrial control machine 4 controls the human-machine interaction device 2 to issue an early warning prompt and record the number of early warnings. If the number of early warnings exceeds the preset number, the assessment personnel are reminded to intervene manually.

[0020] During the practical test, the industrial control machine 4 controls the elevator mirror device 11 and the hard disk recorder NVR5 to start according to the practical test paper, and the hard disk recorder NVR5 controls the camera 6 to realize the recording and video recording of the examinee's process. The elevator mirror device 11 controls the corresponding mirror sub-control 13 according to the practical test paper to respectively manufacture abnormal elevator components and replace the normal elevator components, thereby making the elevator components corresponding to the practical test paper in the elevator device 10 invalid and causing a fault. It means that the number of mirror sub-controls 13 is the same as the abnormal elevator components corresponding to the elevator fault in the practical test bank;

[0021] The examinee observes the fault phenomenon and inspects the second inspection point and the third inspection point, and replaces the abnormal elevator components with the elevator components that the examinee considers to be normal as the practical operation answer, which is transmitted to the management evaluation system 7 through the human-computer interaction device 2;

[0031] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0032] The embodiment of the present invention provides an automatic evaluation system for practical operation examination of elevator repair personnel, comprising:

[0033] The display 1, the human-computer interaction device 2, the identity authentication device 3, the hard disk recorder NVR5, and the elevator mirror device 11 are all connected to the industrial control machine 4, the hard disk recorder NVR5 is connected to the camera 6, the elevator mirror device 11 is connected to the elevator device 10 and are all connected to the detection point 9 (the first detection point), and the industrial control machine 4 has built-in software including a management and evaluation system 7, a question database 8 and an electronic file 12.

[0034] Among them, the management and evaluation system 7 has built-in data collection and analysis, evaluation rules and communication management functions, and it communicates with the elevator mirror device 11 through the industrial control computer 4.

[0035] The elevator mirror device 11 has a built-in mirror controller 18, multiple mirror sub-controllers 13, a mirror door lock switch 16 and a car door lock switch 15. The mirror controller 18 is connected to the multiple mirror sub-controllers 13, and the multiple mirror sub-controllers 13 are respectively connected to the mirror door lock switch 16. One side of the mirror door lock switch 16 is connected to the other side of the car door lock switch 15. One side of the car door lock switch 15 and the other side of the mirror door lock switch 16 are respectively provided with a second detection point 14 and a third detection point 17.

[0036] The question database 8 has built-in question banks for the theoretical part that should be known and the practical part that should be mastered. The question bank for the theoretical part that should be known contains multiple test questions.

[0037] During the theoretical part of the practical test, the identity verification device 3 obtains the candidate information (such as face, second-generation ID card code, etc.) and compares it with the candidate information stored in the electronic file 12 built into the industrial control machine 4. If it is correct, the industrial control machine 4 randomly selects 10 questions from the 100 questions of the theoretical part that should be known in the question database 8 to form a theoretical test paper, and the industrial control machine 4 transmits the test paper to the display 1 for display. The candidate answers the theoretical test questions through the human-computer interaction device 2 (keyboard, mouse and touch screen), and the management and evaluation system generates a theoretical test score sheet. The number of theoretical question banks built into the question database 8 can be increased or decreased through the software configuration file, and the composition rules of the theoretical time can also be adjusted through the software configuration file.

[0038] During the practical part of the practical test, after verifying that the examinee information is correct, the industrial control machine 4 randomly selects 3 questions from the 30 questions in the practical part question bank built into the question database 8 to form a practical test paper, and the industrial control machine 4 transmits the test paper to the display 1 for display. The number of practical question banks built into the question database 8 can be increased or decreased through the software configuration file.

[0039] The question database 8 transmits data with the management and evaluation system 7 through the industrial control machine 4, and is then connected to the elevator mirror device 11 through the industrial control machine 4. The elevator mirror device 11 controls the corresponding mirror sub-control 13 according to the practical test paper to respectively manufacture abnormal elevator components, thereby making the corresponding elevator components in the practical test paper in the elevator device 10 fail, resulting in a malfunction.

[0040] The examinee observes the fault phenomenon of the failure of the elevator component and can use a multimeter to detect the voltage value, resistance value or current value at the two ends of the second detection point 14 and the third detection point 17, so as to quickly confirm the fault, and the management evaluation system 7 conducts practical test evaluation to obtain a practical test score sheet.

[0041] When the management and evaluation system 7 detects that the same examinee has both a theoretical examination transcript and a practical examination transcript, a comprehensive electronic transcript is generated according to preset weights.

[0042] The electronic file 12 saves the theoretical test papers, practical test papers and completed theoretical and practical test papers corresponding to the examinees from the question setting database, saves the operations of the practical examinees' maintenance process, saves the theoretical test transcripts and / or practical test transcripts and comprehensive electronic transcripts from the management and evaluation system 7, and saves the audio and video recordings of the examinees' process through NVR5 and camera 6 for retrospective use. When tracing back, only the examinee's ID number needs to be entered to timely query all the status of the examinee during the examination.

[0043] The data in the electronic file 12 can be statistically analyzed to present the percentage of test error rates, thereby guiding training institutions to train students on knowledge points that need to be strengthened in future training.

[0044] The embodiment of the present invention also provides a method for using the automatic evaluation system for practical examination of elevator repair personnel, comprising the following steps:

[0045] 1. The industrial control computer downloads the candidate information into the electronic file on the platform.

[0046] 2. The identity verification device reads the second-generation ID card information and the sampled face information and compares it with the candidate information in the electronic file. If the management and evaluation system and the question database are started by the industrial control machine, the question database will randomly generate theoretical test papers and practical test papers (practical failure) and store the two test papers in the electronic file under the name of this candidate. If it fails, the industrial control machine will make a voice sound, "Incorrect identity". If it sounds multiple times, the voice will remind the examiner to intervene manually.

[0047] 3. The monitor displays the theoretical test paper in a timely manner, and the candidates are required to answer the theoretical test questions first, which can be done using the keyboard, mouse or touch screen.

[0048] 4. After the examinee answers the questions according to the prompts on the display and submits them, the management and judging system will score the test paper according to the judging rules and store the transcript in the examinee's electronic file. At the same time, the practical test questions will be displayed and the elevator mirror device will be started to switch the faulty elevator mirror components with normal elevator components.

[0049] 5. The practical test for candidates is to find out the faults according to the phenomenon of elevator operation. The management and evaluation system starts the NVR video monitoring and elevator mirror device, and switches the faulty elevator mirror components to the normal elevator components. At this time, the elevator may stop, the fault light may flash, the fault code may be displayed, and so on. Based on the knowledge learned by the candidates, use a multimeter to detect the voltage, current or resistance value at the corresponding detection point. If necessary, use an oscilloscope to detect the waveform. If it is believed that all faults have been found, return to the industrial control machine human-computer interaction device, and according to the practical test paper on the display, replace the faulty elevator mirror components one by one with the normal elevator components, and submit.

[0050] 6. The management and judging system will give scores according to the practical test papers submitted by the examinees and the judging rules, and will store the score sheet in the electronic file of the examinee. At the same time, according to the weight of the theoretical test and the practical test, the final score of the examinee will be obtained, and the electronic score sheet will be formed and stored in the electronic file of the examinee together with the video and audio during the test. The management and judging system will also give instructions based on whether the score sheet is qualified or not. If qualified, the green light will be on, and if unqualified, the red light will be on. Note that there is a time management module inside the management and judging system. If the examinee exceeds the time limit when answering the theoretical test questions and the practical test questions, the examinee will be stopped according to the rules and the score will be given according to the current answering status.

[0051] 7. After the results of this candidate are announced, the management and evaluation system will reset the elevator mirror device through the industrial control computer, so that the elevator device has no mirror components and keeps the elevator in normal operation for the next candidate to take the exam.

[0052] 8. It is explained that there are many actual elevator components, and the practical test is mainly about the maintenance of the electrical part of the elevator. Therefore, the elevator mirror device is mainly the emergency stop switch and disc wheel switch in the machine room in the safety circuit; the upper limit switch, safety clamp switch, car top emergency stop switch, lower limit switch in the well and the car buffer switch, counterweight buffer switch, tensioning wheel switch, pit emergency stop switch in the pit; the main and auxiliary door locks of the hall door and the main and auxiliary door locks of the car door in the door circuit; the running contactor and brake contactor in the brake control circuit, as well as the internal call button, external call button, traction machine encoder and other very common fault components in daily elevator maintenance.
