[0023] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0024] See also Figure 1 and Figure 2The embodiment of the present invention provides a mechanical equipment maintenance training platform, comprising a platform frame 1, a first display device 2 being connected to the upper portion of the platform frame 1, and an operation console panel 3 being provided on the upper surface of the platform frame 1; a host cabinet 4 and a PLC wiring cabinet 5 being provided inside the platform frame 1; wiring holes 6 are provided on the side walls of the host cabinet 4 and the PLC wiring cabinet 5 to facilitate wiring of the host computer in the host cabinet 4 and the PLC controller in the PLC wiring cabinet 5;

[0025] Among them, the first display device 2 is connected to the host in the host cabinet 4 through a circuit, and the operating console panel 3 is connected to the host in the host cabinet 4 through a circuit; the operating console panel 3 is also connected to the PLC controller in the PLC wiring cabinet 5 through a circuit; the host in the host cabinet 4 is also connected to the PLC controller in the PLC wiring cabinet 5 through a circuit.

[0026] In one possible embodiment, the operation console panel 3 is divided into an operation area and a detection area, each of which is equipped with a plurality of detection point jacks. The operation area serves as an input terminal, allowing trainees to simulate mechanical operation and issue corresponding instructions to the PLC controller in the PLC wiring cabinet 5; while the detection area serves as both an input terminal and an output terminal, achieving functional differentiation when different program calls are made. Specifically, when a fault occurs, the detection area can be the output terminal of the relevant fault, while when trainees test the detection points in the detection area, the detection area can be the input terminal of the signal. This configuration can solve the problem of the single function of ordinary single-chip microcomputers. In other words, the maintenance training platform provided by this embodiment, by combining the operation area, the detection area, and the same set of PLC controllers, can respond to faults (prompt fault questions) during trainees' operation training. Trainees can determine the fault by testing the relevant detection point jacks in the detection area and solve the fault through maintenance operations, thereby obtaining real feedback during the fault repair process. That is, after the fault is resolved, the operation can proceed normally and no fault is detected. If the fault is not successfully resolved, the operation area also provides corresponding feedback.

[0027] In a possible embodiment, the operation console panel 3 is divided into four areas: a switch module area 31 , a PLC measurement point module area 32 , a control box module area 33 , and a control box fault detection module area 34 .

[0028] Specifically, after multiple rounds of tests, buttons and detection point jacks that meet the requirements were selected, and the operation console panel 3 was divided into four areas, so that the platform has high security and a certain degree of convenience. The areas are: the switch module area 31 on the upper left side, the PLC measurement point module area 32 on the upper right side, the control box module area 33 on the lower left side, and the control box fault detection module area 34 on the lower right side.

[0029] Among them, the switch module area 31 can include the system power switch, indicator light and voltage detection, power detection integrated module; the PLC measurement point module area 32 is installed with various fault measurement points (detection point jacks); the operation box module area 33 can include the main operation box and auxiliary control box panel, and the operation box fault detection module area 34 can include the measurement points (detection point jacks) of various faults of the operation box. The operator can perform actual operations on the operation console panel 3 according to the platform display.

[0030] Among them, the switch module area 31 can also include the name of the equipment corresponding to the operating console panel 3 (for example, Model A supporting bridge bridge vehicle maintenance training platform), panel operation principle, system indicator light, system fault alarm, key switch, emergency stop switch, detection voltage display area, detection pen, auxiliary control box fault detection point, control terminal power switch fault detection point, power fuse fault detection point, etc.

[0031] The PLC measurement point module area 32 is equipped with various fault measurement points. For example, based on the classification of mechanical modules, these may include modules such as the upper vehicle control box, lower vehicle control box, auxiliary control box, erection frame junction box, crane junction box, bracket junction box, lower vehicle junction box, erection frame hydraulic valve group, crane hydraulic valve group, bracket hydraulic valve group, and outrigger hydraulic valve group. It should be noted that different measurement points can be configured in the PLC measurement point module area 32 for different equipment.

[0032] The control box module area 33 includes a control box switch, an auxiliary control box, and a control terminal power switch. Operators can use toggle switches at each operating switch to facilitate switching between various operations, depending on their needs and operational convenience. Furthermore, the control box module area 33 can be equipped with a power indicator and an online test indicator to facilitate operator detection of any malfunctions in the control box. Furthermore, switch indicators are printed in a prominent area for easy observation and operation.

[0033] Among them, the control box fault detection module area 34 may include detection point jacks for faults in various parts of the equipment, and a detection pen is set in the power supply area, which can be used to perform detection in this area. The voltage status of the detection point is displayed in the power supply area, which is convenient for the operator to determine the area where the fault occurs.

[0034] It can be understood that in the entire maintenance training platform, the output end of the operation area serves as the input end of the PLC controller, which can realize the fault setting of the output actuator. Green and blue indicator lights can be used to replace the actuator, and the measuring point is set at the input end of the PLC controller (the output end of the operation area). The PLC controller controls the simulated actuator according to the fault setting signal sent by the demonstration terminal visual computer. When the control indicator light goes out, since the measuring point is at the input end, the actual PLC controller receives the input signal, that is, sends a normal output signal, so the measuring point signal is normal, which means that the actuator is damaged. When there is no input to the actual PLC controller, the indicator light goes out, and there is no normal electrical signal at the measuring point, then it can be determined that the fault occurs at the input end of the actual PLC controller, and then the next step of analysis and judgment is carried out.

[0035] The PLC controller's I / O unit is the input / output unit. The input unit detects level signals from the field (such as switches, limit switches, temperature switches, pressure switches, etc.) and converts them into low-level signals within the PLC controller. Digital input units are categorized by the number of input points, with 8, 12, 16, and 32 points being common. They are categorized by operating voltage, with 5V, 12V, 24V, AC 110V, and 220V being common. They are further categorized by external wiring method, including sink input and splitter input. The output unit's task is to convert the PLC controller's internal low-level control signals into output signals of the required external level to drive external loads. There are three main types of digital output units: transistor output, relay output, and bidirectional thyristor output.

[0036] Generally, there's a one-to-one correspondence between input points and input signals, and output points and output controls. After allocation, each input and output signal is assigned a number according to the configured channel and contact number. A PLC's input points are the input channels through which the controller receives field information. The accuracy of the input signals is essential for ensuring system control. Meanwhile, the output points of a PLC controller, whether transistors, thyristors, or relays, have limited load capacity. Various potential fault phenomena are simulated using the PLC controller, and corresponding input and output points and measurement points are set up on the operating console. A host computer or industrial computer provides a comprehensive operating system for the training platform. The main operating box, auxiliary control box, and power supply used in actual operations are integrated onto the console panel 3. Different fault problems are presented, and the corresponding faults are simulated using the PLC controller. The operator performs preliminary operations on the display interface, then checks the corresponding measurement points on the console to locate the fault. The fault location is then repaired using the system's internal maintenance system, enabling the operator to learn and master various fault repair methods.

[0037] In a possible embodiment, the PLC controller program writing mainly includes the following parts. First, the fault settings of various parts, including tail leg fault setting, common part fault setting, swing arm fault setting, middle leg fault setting, clutch and crane, lifting pin, up and down pin fault logic, front and rear positioning pin bridge fault, bracket fault logic analysis, erecting frame luffing fault logic, guide beam pushing and retracting and bridge span pushing fault logic, respectively analyzing each fault and writing the corresponding PLC program. Secondly, it also includes the total program block, the fault analysis module for analyzing the above faults, the input measurement point control, the output solenoid valve processing, the upper computer data transmission, the communication, the power and the key module, and the corresponding measurement points, including the travel switch safety output measurement point and the operation box switch input and measurement point. The above PLC program is written and experimentally debugged to meet the equipment requirements of the project.

[0038] It should be noted that the maintenance training platform provided in the embodiment is designed by adopting the modular concept for the operation table panel 3, and the panel can be replaced according to different training needs, that is, different equipment can correspond to different panel designs of the operation table panel 3, so that a plurality of function modules can be expanded and changed, and the applicability is strong.

[0039] Further, based on the modular design, the operation table panel 3 can replace the operation area and the detection area respectively, and then modify the wiring layout of the operation table panel 3 and the PLC controller, so as to realize the effect of partial replacement, and in the case that the PLC controller has enough wiring ports, it can be applied to a plurality of equipment. Moreover, for partial update and upgrade of mechanical equipment, by increasing corresponding measurement points or modifying corresponding measurement points and PLC programs on the operation area and the detection area, the cost of replacing the maintenance training platform can be greatly saved, and the applicability is strong.

[0040] In a possible embodiment, the main cabinet 4 and the PLC wiring cabinet 5 are designed separately, which can reduce the influence of heat on the main machine or the PLC, and metal materials (such as iron) can be used as the materials of the main cabinet 4 and the PLC wiring cabinet 5, and large-area cooling holes are provided on the main cabinet 4 and the PLC wiring cabinet 5 to increase the cooling effect. Further, a reserved cooling space can be provided between the mounting bottom plate and the back of the operation table, for example, the distance between the mounting bottom plate and the back of the operation table can be set to 200 mm, which can increase the cooling range.

[0041] In a possible embodiment, temperature sensors can also be arranged in the main cabinet 4 and the PLC wiring cabinet 5 to monitor the ambient temperature during operation, so as to ensure the operation safety.

[0042] In one possible embodiment, the console panel 3 can be based on the structure of a real-world control box, with input handles, switches, and various indicator lights installed on the console panel 3. The console panel 3 connects to the host computer via serial communication to achieve virtual operation and control. The host computer in the host cabinet 4 can have a built-in virtual simulation system, outputting 2D or 3D images through the first display device 2. The host computer in the host cabinet 4 can be connected to the PLC controller via a bus cable.

[0043] In a possible embodiment, the maintenance training platform may further include a storage cabinet and a keyboard drawer. The storage cabinet may be arranged above the main cabinet 4, and its height may be reserved according to the height difference between the main cabinet 4 and the PLC wiring cabinet 5.

[0044] In one possible embodiment, the maintenance training platform can be designed with a lower front and higher rear. That is, the operating console panel 3 is tilted, with the front lower than the rear. This ergonomic design facilitates operator operation. For example, the front height of the operating console panel 3 is 1000 mm and the rear height is 1120 mm, which meets the operator's need for standing operation.

[0045] In one possible embodiment, the maintenance training platform may further include a second display device 7. It is understood that the second display device 7 may be a display screen, or a virtual reality (VR) or augmented reality (AR) device. The function of the second display device 7 is to present relevant images to the operator under the control of the host.

[0046] Among them, when the second display device 7 is a display screen, the maintenance training platform can be used as a dual screen.

[0047] In a possible embodiment, a switch may be further provided in the maintenance training platform. The switch is used to connect multiple maintenance training platforms and is applicable to operation and maintenance training scenarios of multiple identical or different equipment.

[0048] It is understood that multiple maintenance training platforms can be connected to the teacher's server via a switch. The teacher's server can manage each maintenance training platform using training management software. For example, the teacher can check whether a connected maintenance training platform is online or offline. Furthermore, the instructor can use the teacher's server to specify training content for each student's maintenance training platform. For example, during an exam, the assessment content for each student's maintenance training platform can be customized to avoid plagiarism.

[0049] Furthermore, the trainee's operation process in the maintenance training platform can be recorded by the server and stored in local or cloud storage space. In subsequent teaching analysis and summary, these records can be used to analyze the errors made by the trainee during operation and provide targeted training and teaching, thereby improving teaching effectiveness.
