[0044] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example 1

[0046] See also Figure 1 and Figure 2Embodiment 1 of the present invention provides an interactive method for equipment maintenance training, comprising the following steps:

[0047] S1, responding to the operation instruction of the operator in the operation console panel 13, obtaining the current operation event corresponding to the operation instruction, and sending the event screen corresponding to the current operation event to the display device 11 and the server 12;

[0048] S2, the server 12 randomly generates a fault event according to the current operation event; the server 12 sends the randomly generated fault event to the PLC controller 14;

[0049] S3, responding to the maintenance instruction of the operator in the operation console panel 13 for the fault event, generating a maintenance event according to the maintenance instruction, and sending an event screen corresponding to the maintenance event to the display device 11 and the server 12;

[0050] S4. The server 12 generates a training result according to the maintenance event, and displays the event screen corresponding to the current operation event, the event screen corresponding to the maintenance event, and the training result through the display device 11.

[0051] In this embodiment, by ensuring the authenticity of the simulated installation of the operation console panel 13, the consistency of the operation process, the accuracy of the functional simulation, the synchronization of the feedback mechanism, etc., it can be ensured that when the trainees operate on the maintenance operation platform panel, their operating methods are completely consistent with the actual operation.

[0052] Specifically, the layout, buttons, switches, indicator lights, etc. of the operation console panel 13 are highly consistent with the actual equipment, so that the trainees can have a deep understanding of the actual equipment while operating on the maintenance operation platform panel. In addition, through the connection between the operation console panel 13 and the PLC controller 14, the operation console panel 13 can accurately simulate the various functions of the actual equipment. On the operation console panel 13, the same operation process as the actual equipment is set, that is to say, whether it is starting, stopping or troubleshooting, the operation steps on the operation console panel 13 can be consistent with those on the actual equipment. If the actual equipment has a certain specific failure mode, the operation console panel 13 can also simulate this failure mode so that the trainees can troubleshoot and handle it on the platform; further, the feedback mechanism (such as indicator lights, display screens, etc.) on the operation console panel 13 is synchronized with the actual equipment. When operating on the operation console panel 13, the feedback mechanism should reflect the operation results in real time so that the trainees can accurately judge the correctness and effect of the operation. When the trainees make mistakes during the operation, they will not be able to proceed to the next step, and the information of the wrong operation will be fed back to the trainees through the feedback mechanism.

[0053] In this embodiment, according to the communication protocol used (such as Modbus, Profinet, etc.), corresponding communication parameter settings such as baud rate, data bit, stop bit, etc. can be performed in the PLC controller to ensure that the communication configuration between the operation console panel 13 and the PLC controller matches. In addition, programming software compatible with the PLC controller (such as TIAPortal of Siemens, GX Works of Mitsubishi, etc.) can be installed on the server 12, and the server 12 can be connected to the PLC controller through an appropriate interface (such as USB, Ethernet, etc.). In the programming software, a new PLC program can be created or imported from an existing project. The program should include the processing logic for the input signal of the operation console panel 13. In the program, a unique input address is assigned to each button, switch or knob on the operation console panel 13. These addresses will be used to identify and process the signal from the operation console panel 13 in the PLC program. According to the input signal of the operation console panel 13, the corresponding output instruction is written. For example, when a button is pressed, the PLC may need to perform a specific action or send a specific signal to other devices. Then the written and debugged program is downloaded from the computer to the PLC. Furthermore, before downloading the program to the PLC, the simulation function of the programming software can be used for debugging to ensure that the program can correctly respond to the input signal of the operation console panel 13 and generate the expected output instruction.

[0054] Among them, by simulating various potential fault phenomena and setting the corresponding input and output points and measuring points of the PLC on the operating console panel 13, the host or industrial computer provides an overall operating system for the training platform, and the main operation box, auxiliary control box, power supply, etc. used in actual operation are integrated on the operating console panel 13. The system provides different fault questions and simulates the corresponding faults through the PLC system. The operator performs preliminary operations through the display interface, and then detects the corresponding measuring points on the operating console to find the location of the fault. The corresponding position is repaired through the maintenance system in the system, so as to achieve the purpose of learning and mastering various fault repair methods.

[0055] In this embodiment, the server 12 randomly generates fault events according to the current operation event: obtains a target fault event set matching the current operation event from the preset fault tree; randomly retrieves a target fault event from the target fault event set and sends it to the PLC controller 14; generates maintenance events according to the maintenance instructions: obtains maintenance instructions in sequence, connects them in series according to the order and content of the maintenance instructions, and generates the maintenance event. The server 12 generates training results according to the maintenance event, and determines whether the order and content of the maintenance instructions are correct: if the order and content of the maintenance instructions are correct, the training result is determined to be a successful maintenance; if at least one of the order and content of the maintenance instructions is wrong, the training result is determined to be a failed maintenance.

[0056] In this embodiment, a fault tree is stored in the server 12, and the fault tree includes at least one fault event set, and the fault event set includes at least one of the fault events; the fault event set includes a hydraulic fault event set and an electrical fault event set: the hydraulic fault event set includes equipment faults and equipment hydraulic valve fault events; the electrical fault event set includes fault events of preset locations in the PLC.

[0057] In traditional fault maintenance training, a fault manifestation is usually given directly, and the trainees are required to infer the possible fault causes based on the fault manifestation, and then conduct troubleshooting one by one to solve the fault problem. In this embodiment, the fault tree is constructed in the form of questions, that is, each fault event corresponds to a corresponding operating state. For example, when the trainee performs the "swing arm" operation instruction on the equipment, the operating state is "swing arm state" at this time, and the upper / lower swing arm retracting or unfolding failure may occur randomly, so the trainee needs to repair it, which conforms to the actual scene and operation logic. For the trainee, when repairing the fault, it can be combined with the prompt in the display device 11 (the engine part has a fault, but the oil circuit is intact), and a multimeter or electric pen and other test tools can be used to troubleshoot the fault, and corresponding options (such as oil circuit fault, engine fault, circuit fault) can be given, so that the maintenance training can be carried out more specifically, without the need for the trainee to blindly look for the source of the fault, resulting in an infinite loop, thereby improving the efficiency of the training.

[0058] Among them, for different types of faults, they are solved by fault maintenance personnel in different fields. For example, mechanical faults, hydraulic faults, and electrical faults all require fault maintenance personnel in the corresponding fields to repair them. Therefore, the matching fault type can be confirmed according to the field of the fault maintenance personnel (which can be obtained from the trainee's identity information, etc.). Trainees can use a detection pen to detect each measuring point set in the operation console panel 13 to determine the fault. The difference between electrical faults and hydraulic / pneumatic faults is that the names of the measuring points are different, and mechanical faults can be determined by combining electrical and hydraulic / pneumatic faults.

[0059] In a possible embodiment, the setting of the fault tree can be divided into multiple levels. First, it can include the fault settings of various parts, such as the common part fault settings, swing arm fault settings, middle leg fault settings, clutch and crane, and analyze and experiment each fault separately to write the corresponding PLC program. Secondly, it can also include the overall program block, the fault analysis module for analyzing the above faults, the input measurement point control, the processing of the output solenoid valve, the upper computer data transmission, communication, power supply and key module, and the corresponding measurement points, including the travel switch insurance output measurement point and the operation box switch input and measurement point.

[0060] In detail, the fault tree can also be divided into detailed faults corresponding to various parts of the equipment, such as upper / lower arm retraction or expansion fault, middle outrigger extension / retraction fault, clutch disengagement / closing fault, crane forward / reverse rotation fault. Under various faults, there are also multiple causes, such as fuse failure, power fuse / cable failure in the main control box, main control box power switch failure, main control box emergency stop switch failure, main control box erection / outrigger switching switch failure, and corresponding hydraulic system switch failure, solenoid valve and its PLC failure, etc.

[0061] It is understandable that fault tree analysis is a systematic fault analysis method used to identify the root causes and possibilities of system failures. In the maintenance assessment questions, fault tree analysis can be used to design relevant questions to assess the maintenance personnel's understanding and response capabilities to system failures. In the process of constructing the fault tree, it is necessary to clarify which operations may trigger which fault events, which can be achieved through a mapping table or database, in which each operation is associated with one or more possible fault events. For some key faults, they may appear as high-frequency faults and may appear in multiple operating states / events, such as engine failures, clutch disengagement / closing failures, etc. In addition, in the process of randomly retrieving target fault events from the target fault event set, the weights of key faults can be set, so that the frequency of occurrence of key faults is higher, thereby improving the students' mastery and application capabilities of these key faults.

[0062] In this embodiment, the display device 11 is configured with a first display device and a second display device; the first display device is used to display the login interface, the system main interface, the question number of the maintenance theory training assessment, and the question of the maintenance practical training assessment; the second display device is used to display the rendering, the detailed structure, the answer area of ​​the maintenance theory training assessment, and the maintenance practical training assessment. Among them, the second display device is a VR device, and the VR device includes a VR helmet display terminal and a VR handle. The VR device communicates with the server 12 via a data cable. In this way, the maintenance scene can be simulated more realistically, so as to achieve the purpose of making the operator feel as if they are in the scene, and improve the training effect.

[0063] In a possible embodiment, the objects corresponding to the maintenance instructions include two modules: theoretical maintenance training and operational maintenance training. For theoretical maintenance training, it mainly focuses on principle questions and answers, and trainees can answer them through the display screen. For operational maintenance training, trainees need to first perform normal mechanical simulation operations according to the prompts. Trainees can issue operating instructions through the main control box on the operating console panel 13, etc. The PLC controller 14 collects the control signals of each part and sends them to the demonstration terminal visual computer to drive the three-dimensional visual action. At the same time, the main control PLC receives the fault setting signal of the demonstration terminal visual computer and controls the corresponding relay to disconnect to achieve fault simulation.

[0064] After entering the operation and maintenance training, the first display device displays the answer area, and the fault is judged step by step according to the judgment process - according to the fault phenomenon and fault prompt, the circuit is determined by checking the electrical circuit diagram, and the electrical path is tested on the display console to determine the cause of the fault. Then, select the fault cause option corresponding to the fault phenomenon at the fault cause.

[0065] The second display device is the operation and maintenance training area. Different fault causes correspond to the repair of different structural parts. Regardless of whether the fault cause is selected correctly or not, the operation and maintenance training of the corresponding option will be displayed.

[0066] It should be noted that after the fault repair is completed, the trainee checks whether the fault point has been eliminated again on the operation console panel 13 and whether the corresponding structure can work normally by turning the control box to check whether the repair is correct.

[0067] Among them, during the entire maintenance training process, there is also an assessment of the disassembly and assembly steps. That is to say, trainees cannot make the maintenance successful by entering all the maintenance instructions, but need to execute the maintenance instructions according to the correct steps (for example, which component to remove first and which component to remove later, which component to install first and which component to install later) to get the correct maintenance feedback. If the steps are wrong, the maintenance will not be successful. This is in line with the actual maintenance process.

[0068] In summary, the present invention responds to the operation instructions of the operator in the operation console panel 13, obtains the current operation event corresponding to the operation instruction, and sends the event screen corresponding to the current operation event to the display device 11 and the server 12; the server 12 randomly generates a fault event according to the current operation event; the server 12 sends the randomly generated fault event to the PLC controller 14; responds to the maintenance instruction of the operator to the fault event in the operation console panel 13, generates a maintenance event according to the maintenance instruction, and sends the event screen corresponding to the maintenance event to the display device 11 and the server 12; the server 12 generates a training result according to the maintenance event, and displays the event screen corresponding to the current operation event, the event screen corresponding to the maintenance event, and the training result through the display device 11. The present invention can respond to faults when trainees are conducting operation training, obtain real feedback in the fault maintenance process, and improve the training effect and training efficiency.
