Description

Technical Field

[0001] This application belongs to the field of electrical training technology, specifically relating to an electrical training platform. Background Technology

[0002] The operation, maintenance, and fault diagnosis of industrial electrical equipment are crucial for ensuring the continuity and safety of modern industrial production. Especially in process industries (such as pulp and paper, chemical, and metallurgical industries), a large number of specialized electrical devices such as relay protection devices, motor control center (MCC) cabinets, and frequency converters are used. These systems are complex and have proprietary logic, placing extremely high demands on the skill levels of maintenance personnel. Therefore, electrical training devices for skills training have emerged, becoming an important tool for enterprises to cultivate highly skilled technical workers.

[0003] Technological development in this field primarily focuses on standardized training platforms for fundamental skills applicable across multiple industries. These devices typically provide basic power modules, measuring instruments, and standardized terminal blocks, with an emphasis on training trainees in electrical drawing interpretation, safety regulations, and basic wiring skills.

[0004] However, for specific industry equipment, such as the inability to simulate the unique functional logic of imported equipment in the pulp and paper industry, the training content is disconnected from the actual production scenario, resulting in weak skill transferability among maintenance personnel.

[0005] In addition, training platforms customized for specific industries are expensive (the cost of a single unit generally exceeds 100,000 yuan), and their structure is fixed, making it impossible to freely assemble them according to the model and parameters of the equipment in operation by the enterprise. This makes it difficult to adapt to the customized training needs of enterprises, resulting in a high rate of equipment idleness.

[0006] Therefore, existing technologies and equipment cannot simultaneously meet the needs of effectiveness and relevance in skills training at a lower cost. Summary of the Invention

[0007] This application provides an electrical training platform that enables full-process, multi-functional hands-on training of industrial electrical components, solving the problems of existing training devices being unable to reuse real equipment due to their fixed physical structure and single electrical function, training content being detached from actual production, and high costs for dedicated training.

[0008] The technical solution adopted in this application is as follows: An electrical training platform, comprising: The main frame encloses at least one mounting area, and the main frame includes an upper frame, a lower frame, a left frame, and a right frame that enclose the mounting area; At least one set of mounting structures, each mounting area is provided with one set of mounting structures, the mounting structure includes at least one horizontally extending crossbeam to divide the mounting area into multiple mounting positions for mounting electrical components, the two ends of the crossbeam are respectively connected to the left frame and the right frame, and can slide along the left frame and the right frame to adjust the size of the mounting position; An electrical function platform is set on the main frame, and the electrical function platform includes a signal interface module and a power supply module; The signal interface module is configured to provide input signals to the electrical components and receive output signals from the electrical components; The power supply module is configured to provide power to the electrical components to meet their power supply requirements.

[0009] The electrical training platform used in this application also has the following additional technical features: The left frame and the right frame are arranged parallel to each other, with at least a portion of their areas extending vertically. The left frame and the right frame are provided with longitudinally extending mounting grooves on the side facing the mounting area. The crossbeam has mounting ends at both ends that mate with the mounting grooves, so that the crossbeam can slide along the left frame and the right frame.

[0010] The mounting structure also includes a fastener that can slide along the mounting groove to fix the crossbeam.

[0011] Each of the crossbeams is provided with two fixing members, which are respectively located at the left and right ends of the crossbeam and at the top and bottom sides of the crossbeam.

[0012] A fixing member is provided at the connection between the upper frame and the left frame or the right frame, and a fixing member is provided at the connection between the lower frame and the left frame or the right frame. There are two fasteners in the same mounting position, and the two fasteners are located on the same side of the left and right sides of the mounting position.

[0013] The lower frame extends horizontally, and the upper sides of the lower frame and the crossbeam are provided with mounting grooves extending horizontally. The mounting structure also includes a limiting member that can slide along the mounting groove to adjust the lateral dimension of the mounting position.

[0014] The main frame encloses multiple mounting areas, which are arranged on both sides of the electrical functional platform.

[0015] The signal interface module includes an input / output terminal block, which includes multiple digital input terminals, multiple digital output terminals, and an analog interface.

[0016] The electrical function platform also includes a human-computer interaction module, which includes: Multiple status indicator devices, whose control terminals are electrically connected to the signal interface module, are used to visually display the output status of the electrical components; Multiple manual control switches, the outputs of which are electrically connected to the signal interface module, are used to provide analog input signals or control commands to the electrical components.

[0017] The status indicator includes a dual-color indicator light, and the manual control switch includes a toggle switch and / or a button.

[0018] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows: 1. In this application, by integrating a dedicated mounting area and structure onto the main frame, a basic carrier is provided for the physical fixation of real industrial electrical components of varying sizes (especially equipment to be reused after production line shutdowns). Simultaneously, the electrical function platform, with its signal interface module and power supply module, provides these components with the necessary input-output signal channels and diverse power supplies, thus achieving unified support and drive of non-standard physical equipment on a single platform. This allows enterprises to directly use real equipment being replaced on the production line (such as relay protectors and frequency converters of different specifications) for practical training, solving the problem of a serious disconnect between training content and actual production caused by the inability to install and drive such equipment on training platforms in the past.

[0019] Secondly, the electrical function platform, through its signal interface module, can provide simulated field input signals (such as fault quantities and status quantities) to the mounted electrical components and receive output signals (such as action commands and alarm signals) from the components. Combined with the adapter power provided by the power supply module, it enables the actual equipment to operate under conditions closely resembling real-world working conditions. This allows training to extend beyond basic wiring to include in-depth skills training in areas such as equipment function verification, logic debugging, fault simulation, and troubleshooting, significantly improving the effectiveness and relevance of the training.

[0020] The modular architecture (mounting area / structure, signal interface, power supply) is a universal platform adaptable to various devices. Enterprises do not need to purchase separate simulation training devices for each type of specialized equipment; they can simply use this platform to mount different off-line devices to build diverse training scenarios. This greatly improves the utilization rate of training resources, reduces the construction and updating costs of dedicated training systems, and allows training content to be synchronously and rapidly adjusted as the enterprise's production equipment iterates.

[0023] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0025] It should be noted that in the description of this application, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on their own orientation or positional relationship, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0026] like Figure 1 As shown, an electrical training platform includes: The main frame 1 encloses at least one mounting area 11, and the main frame 1 includes an upper frame 111, a lower frame 112, a left frame 113, and a right frame 114 that enclose the mounting area 11. At least one set of mounting structures 2, each mounting area 11 is provided with a set of mounting structures 2, the mounting structure 2 includes at least one horizontally extending crossbeam 21 to divide the mounting area 11 into a plurality of mounting positions 115 for mounting electrical components, the two ends of the crossbeam 21 are respectively connected to the left frame 113 and the right frame 114, and can slide along the left frame 113 and the right frame 114 to adjust the size of the mounting position 115; An electrical function platform 3 is set on the main frame 1. The electrical function platform 3 includes a signal interface module 31 and a power supply module 32. The signal interface module 31 is configured to provide input signals to the electrical component and receive output signals from the electrical component; The power supply module 32 is configured to provide power to the electrical components to meet their power supply requirements.

[0027] This application aims to provide an electrical training platform. Its core concept is to integrate a specific physical load-bearing area (mounting area 11 and mounting structure 2) and a multi-functional electrical support center (electrical function platform 3) on the main frame 1 to construct a unified training device that can flexibly fix real industrial electrical components of various sizes and provide them with a complete operating environment, thereby achieving a high degree of integration of theory and practice and effectively utilizing the resources of off-line equipment of enterprises.

[0028] The main frame 1 constitutes the physical skeleton of the training platform, and the at least one mounting area 11 enclosed by it serves as a dedicated space for mounting electrical components. The mounting structure 2 is set in this area, and its core function is to provide a universal, non-fixed mounting interface to replace the standard, hole-fixed mounting plates on traditional training platforms.

[0029] A preferred strategy is to employ a rectangular or near-rectangular frame structure enclosed by an upper frame 111, a lower frame 112, a left frame 113, and a right frame 114. It should be noted that the upper frame 111, lower frame 112, left frame 113, and right frame 114 that enclose the mounting area 11 are based on the orientation of the electrical training platform under normal operating conditions.

[0030] This enclosed design not only provides a stable supporting framework for the entire training platform, but also physically defines and isolates the space used to mount electrical components.

[0031] The core of the mounting structure 2 is at least one horizontally extending crossbeam 21. The two ends of the crossbeam 21 are slidably mounted (or mounted) on the left frame 113 and the right frame 114, respectively. The connection between the crossbeam 21 and the left and right frames allows it to slide along the left frame 113 and the right frame 114 to adjust the size of the mounting position 115. The left frame 113 and the right frame 114 provide a precise guiding foundation for the crossbeam 21, ensuring its vertical sliding and enabling adjustment of the height of the mounting position 115.

[0032] For example, mounting area 11 can be designed as an open area with vertical mounting guidance, which can hold equipment of different heights by means of crossbeams and clamps that can slide up and down and lock; its width should be designed to accommodate the wider equipment (such as some frequency converters or MCC units) as intended.

[0033] The electrical function platform 3 is mounted on the main frame 1, usually in a position that is easy for the operator to observe and access, such as in front of or to the side of the mounting area 11.

[0034] The electrical function platform 3 includes two types of core function modules: The signal interface module 31 is configured as a centralized signal routing and access point. It contains a large number of input / output (I / O) interfaces, such as industrially common quick-connect terminal blocks. These terminals are divided into input terminals that provide analog field signals and output terminals that receive feedback signals from the receiving device.

[0035] By providing connecting cables of different specifications (such as 2.5mm² quick-connect cables), trainees can easily connect the mounted electrical components (such as the current and voltage input terminals of protection devices, and trip output contacts) to these terminals. The function of this module is to establish a manually controllable signal channel, allowing trainers or trainees to simulate various operating condition signals (such as simulated overcurrent and undervoltage faults) to the equipment and capture the equipment's response signals.

[0036] The power supply module 32 is configured as a multi-voltage, multi-type power output center. It must cover the common power supply needs of the target industrial equipment, including at least three-phase AC 380V and single-phase AC 220V for drive motors and other power equipment, as well as DC 24V for control circuits and electronic boards. The module integrates transformers, rectifier circuits, circuit breakers, and leakage current protectors to ensure power output compliance and operational safety. This module provides the necessary electrical energy for the normal operation of all mounted electrical components.

[0037] The mounting structure 2, signal interface module 31, and power supply module 32 do not operate in isolation, but rather work closely together with the training logic through electrical connection.

[0038] The typical steps for implementing full-process training are as follows: First, based on the dimensions of the electrical component being installed, adjust and secure the mounting structure 2 within the mounting area 11, ensuring the component is firmly installed. Then, connect the component's power input terminal to the corresponding voltage output terminal of the power supply module 32, and connect its signal input / output terminals to the corresponding quick-connect terminals of the signal interface module 31. After preparation, power on the device via the power supply module 32, and the equipment enters standby mode.

[0039] During training, the operator can apply specific analog or digital signals (simulating faults or operating conditions) to the signal input terminal of the equipment using external instruments (or by utilizing the signal interface module 31 itself, if it integrates a simple signal generation function). The internal logic circuit of the equipment processes these signals. The processing results (such as relay action or alarm output) will be reflected on the corresponding output terminal of the signal interface module 31 through its output terminal.

[0040] Trainees can verify device functionality, analyze logic, or diagnose preset faults by measuring the state changes of these terminals or observing external indicator lights connected to the output terminals. This process fully replicates the entire closed loop from signal excitation and internal device logic judgment to action result output, achieving in-depth practical training in principle verification and fault diagnosis.

[0041] It should be noted that, regardless of whether it is a standardized training platform, its structure is fixed and the size and hole positions of the mounting panel are standardized. It can only be used to fit small teaching modules or general-purpose devices. It cannot accommodate and fix real equipment with different sizes and special interfaces in the actual production line (such as frequency converters and large relay protection panels), resulting in the training content being disconnected from the actual equipment on the production site.

[0042] Alternatively, customized simulation training devices are available, but their R&D costs are extremely high, their structure is closed, and their functions are limited. A single device typically only targets a single piece of equipment or system. For companies with multiple types and brands of off-line equipment that need to be reused, purchasing multiple sets of such dedicated devices is not economical, and they cannot flexibly adjust the training content according to their own equipment updates, resulting in a high risk of equipment idleness and obsolescence.

[0043] Existing solutions cannot provide a unified platform that can adapt to devices of various physical sizes and offer comprehensive electrical functionality support at a low cost. Enterprises often face the choice of purchasing a general-purpose platform with limited functionality that cannot accommodate real equipment, or purchasing a simulation platform with fixed functions that cannot reuse old equipment.

[0044] This application can quickly construct a variety of customized training scenarios by equipping different decommissioned devices, enabling retired equipment of different sizes and models in the enterprise warehouse to be conveniently mounted and used for teaching, greatly expanding the sources of training resources and solving the contradiction between training content and actual production equipment.

[0045] Therefore, companies do not need to invest in purchasing dedicated simulators for each specific piece of equipment, which greatly reduces the initial investment and long-term update costs of building a comprehensive, high-level corporate training center, achieving a balance between economic benefits and training quality.

[0046] In a preferred embodiment of this application, at least a portion of the left frame 113 and the right frame 114 are arranged parallel to each other along a vertical line. The left frame 113 and the right frame 114 are provided with longitudinally extending mounting grooves on the side facing the mounting area 11. The crossbeam 21 has mounting ends at both ends that cooperate with the mounting groove, so as to enable the crossbeam 21 to slide along the left frame 113 and the right frame 114.

[0047] The core of this implementation method is to construct an installation area with a clear structure, good rigidity, and high adjustability, so as to quickly and stably mount electrical components of different heights and sizes, and optimize the space utilization of the training platform.

[0048] The left frame 113 and the right frame 114 are arranged parallel to each other with at least a portion extending vertically. They are connected to the horizontal upper frame 111 and lower frame 112, together defining at least one clear and open mounting area 11. Specifically, the main frame 1 adopts a rectangular or approximately rectangular frame structure enclosed by the upper frame 111, lower frame 112, left frame 113, and right frame 114. This invention does not impose any limitations on this.

[0049] In addition, at least a portion of the left frame 113 and the right frame 114 are arranged parallel to each other along the vertical direction, providing a precise and parallel guiding foundation for the crossbeam 21, ensuring the sliding of the crossbeam 21 and the adjustment of the height of the mounting position 115.

[0050] Specifically, the left frame 113 and the right frame 114 are provided with longitudinally extending mounting grooves on the side facing the mounting area 11. The crossbeam 21 has mounting ends at both ends that cooperate with the mounting groove, so as to enable the crossbeam 21 to slide along the left frame 113 and the right frame 114.

[0051] On the inner sides of the left frame 113 and the right frame 114 (i.e., the side facing the mounting area 11), each is machined or fitted with a mounting groove extending vertically (longitudinally). This mounting groove serves as the core guide reference for the entire adjustment system, and its longitudinal extension provides a precise linear path for the up-and-down movement of the crossbeam 21. This groove can be a T-groove, a U-groove, or a guide groove with a specific lip.

[0052] Corresponding to the mounting groove, a mounting end is provided at each of the left and right ends of the crossbeam 21. This mounting end is a component specifically designed to mate with the mounting groove. Its shape matches the inner cavity of the mounting groove; for example, it can be a T-block mates with a T-groove, a slider mates with a U-groove, or a protrusion, bearing, or roller structure that can be embedded in and slide along the groove.

[0053] During actual assembly, the mounting ends of the crossbeam 21 are placed into the mounting slots of the left frame 113 and the right frame 114, respectively. Because the shape of the mounting ends is constrained within the contour of the mounting slots, the crossbeam 21 can only slide freely along the extension direction of the mounting slots (i.e., the vertical direction), and cannot sway or detach in the horizontal plane. By manually applying force, the crossbeam 21 can be moved up and down within the mounting slots via its mounting ends, thereby steplessly adjusting the installation height of the crossbeam 21.

[0054] In addition, the mounting structure 2 also includes a fastener 22 that can slide along the mounting groove to fix the crossbeam 21.

[0055] The main objective of this embodiment is to solve the problem of how to securely lock and fix the crossbeam 21 after it slides along the mounting groove to the desired height. It aims to provide a dedicated fixing mechanism that matches the sliding guide structure (mounting groove) to ensure that the crossbeam 21 and the electrical components it carries maintain absolute positional stability during training, preventing accidental displacement due to vibration, operating force, or the equipment's own weight, thus ensuring operational safety and training effectiveness.

[0056] The fastener 22 is an independent mechanical part or component whose core design feature is that it can mate with the longitudinally extending mounting groove and slide within it. This means that the fastener 22 has a sliding part that matches the cross-sectional shape of the mounting groove, such as the head of a T-bolt, a square slider, or a locking block with rollers, so that it can smoothly fit into the mounting groove and move longitudinally along the groove.

[0057] The fastener 22 is not isolated; its design is associated with the crossbeam 21 to serve the function of fixing the crossbeam 21. A typical strategy is to have a connecting structure (such as a threaded hole, gripper, or hook) on the fastener 22, which, in conjunction with a corresponding connection point (such as a through hole or groove) at the end of the crossbeam 21, physically connects or presses the two together.

[0058] After the crossbeam 21 slides to the target height within the mounting groove via its mounting end, the fixing member 22 is moved within the mounting groove to a height position corresponding to the end of the crossbeam 21. Then, the locking mechanism on the fixing member 22 is operated (e.g., tightening the nut, turning the eccentric handle, or pressing down the locking tongue) to generate strong static friction between the fixing member 22 and the inner wall of the mounting groove, or to cause deformation or displacement of a part of the fixing member 22, thereby locking the mounting groove and simultaneously pulling or pressing the crossbeam 21 tightly towards or against the frame. This effectively restricts any movement of the mounting end of the crossbeam 21 within the mounting groove, thus achieving the fixation of the crossbeam 21.

[0059] Specifically, each of the crossbeams 21 is provided with two fixing members 22, which are respectively located at the left and right ends of the crossbeam 21 and at the top and bottom sides of the crossbeam 21.

[0060] For each individual crossbeam 21, two fasteners 22 are configured. These two fasteners 22 are arranged symmetrically, with one corresponding to and acting on the left end region of the crossbeam 21, and the other corresponding to and acting on its right end region. Specifically, the left-end fastener 22 is installed in the mounting groove of the left frame (left frame 113) and connected or pressed against the left end of the crossbeam 21; the right-end fastener 22 is installed in the mounting groove of the right frame (right frame 114) and associated with the right end of the crossbeam 21.

[0061] When adjusting the height of the crossbeam 21, the two fixing members 22 can be pre-positioned in a relaxed or following state within their mounting slots. After the crossbeam 21 slides to the target height, the operator needs to tighten the left and right fixing members 22 respectively. By tightening the bolts or turning the eccentric handle, the left fixing member 22 is locked into the mounting slot of the left frame 113, securing the left end of the crossbeam 21, while the right fixing member 22 is locked into the mounting slot of the right frame 114, securing the right end of the crossbeam 21. These two fixing points work together to achieve full constraint fixation of the crossbeam 21.

[0062] From a mechanical perspective, the crossbeam 21 is subjected to its own vertical gravity and the vertical gravity of the equipment it carries. With a fixed point at each end, it forms a symmetrical, two-point-supported statically determinate structure. This constraint method most effectively resists the tendency of the crossbeam 21 to twist around its axis, ensuring it remains horizontal and avoiding component tilting that could occur due to unilateral constraint. This, in turn, guarantees the uprightness and stability of the electrical components mounted on it.

[0063] Compared to single-point fixing, dual-point fixing significantly reduces the shear force and torque borne by each fixing point, making the fixation more reliable. Even in training scenarios with high loads or vibrations (such as motor operation), it can effectively prevent loosening of the fixation due to long-term stress or impact, greatly enhancing the safety and durability of the entire mounting system.

[0064] The two fasteners 22 are respectively disposed on the upper and lower sides of the crossbeam 21. It can be understood that the fasteners 22 generally protrude toward the mounting position 115, which forms a mechanical obstacle to the installation of electrical components and reduces the maximum size of the electrical components that can be installed.

[0065] If both fasteners 22 are placed under the crossbeam 21, the width of the mounting position 115 below them will be limited by the width of the two fasteners 22. Similarly, if both fasteners 22 are placed on the crossbeam 21, the width of the mounting position 115 above them will be limited by the width of the two fasteners 22.

[0066] Furthermore, it is understood that for a crossbeam 21, two fixing members 22 are provided, which are respectively provided at the left and right ends of the crossbeam 21 and at the top and bottom sides of the crossbeam 21.

[0067] When one fastener 22 is located at the left end and upper side of the crossbeam 21, and another fastener 22 is located at the right end and lower side of the crossbeam 21, the electrical components are placed on the right side of the mounting position 115 above the crossbeam 21. Most of the force is borne by the fastener 22 located at the right end and lower side, reducing the force on the fastener 22 located at the left end and upper side. This reduces the force on the fastener 22 located at the left end and upper side and the crossbeam 21, further preventing long-term tensile deformation and ensuring the stability of the mounting structure.

[0068] Specifically, a fastener 22 is provided at the connection between the upper frame 111 and the left frame 113 or the right frame 114, and a fastener 22 is provided at the connection between the lower frame 112 and the left frame 113 or the right frame 114. The same mounting position 115 has two fixing members 22, and the two fixing members 22 are located on the same side of the left and right sides of the mounting position 115.

[0069] The installation positions of the two fasteners 22 are specifically associated with the structural nodes of the main frame 1. That is, one fastener 22 is located at the connection between the upper frame 111 and the left frame 113 (or the right frame 114), and the other fastener 22 is located at the connection between the lower frame 112 and the left frame 113 (or the right frame 114). They themselves serve as reinforcements in the connection of the frame corners.

[0070] For a specific mounting position 115 formed by the crossbeam 21, the two fasteners 22 serving the mounting position 115 (one on the upper side and one on the lower side) are designated to be located on the same side of the left and right sides of the mounting position 115. For example, both are located on the left side of the mounting position 115 (i.e., both are installed at the connection between the left frame 113 and the upper and lower frames 112), or both are located on the right side.

[0071] Placing two fasteners 22 within the same mounting position 115 on the same side reduces the size restrictions on electrical components. The electrical components are then placed on the opposite side of the left and right sides of the mounting position 115. This ensures that the fasteners 22 within adjacent mounting positions 115 are located on different sides of the left and right, and vice versa. This results in the entire frame being subjected to uniform force, reducing bending moments and other forces on the frame, maintaining frame shape stability, and facilitating the sliding adjustment of the crossbeam 21.

[0072] Furthermore, a single horizontally arranged crossbeam 21 can itself serve as a basic suspension or support beam. By setting multiple such crossbeams 21 (e.g., two parallel ones) and installing electrical components between or above them, different mounting positions 115 are naturally defined in the vertical direction.

[0073] More specifically, the space between the upper and lower crossbeams 21 forms a mounting position 115, which can be used to clamp and fix equipment; or, each crossbeam 21 can itself serve as an independent mounting position 115, used to fix equipment using clamps. Depending on the specific height of the electrical component to be installed (e.g., a 550mm high frequency converter or a 200mm high protection device), the vertical space size of each mounting position 115 can be flexibly defined by adjusting the relative distance between the crossbeams 21, thus adapting to the installation requirements of electrical components of different heights.

[0074] Furthermore, the entire mounting area 11 is divided into multiple mounting positions 115 with customizable heights. This allows multiple electrical components of different sizes to be installed side by side or vertically within a single mounting area 11, such as mounting a relay group at the top and a signal converter at the bottom, greatly improving space utilization and the functional integration of the training platform.

[0075] In a preferred embodiment of the present invention, the lower frame 112 extends horizontally, and the upper sides of the lower frame 112 and the crossbeam 21 are provided with mounting grooves extending horizontally. The mounting structure 2 also includes a limiting member 23 that can slide along the mounting groove to adjust the lateral dimension of the mounting position 115.

[0076] The main objective of this embodiment is to provide a technical means for flexibly adjusting the lateral dimensions of the mounting position 115, building upon the existing height adjustment capability. Its core is to address the issue of dimensional differences in the width direction of electrical components. Through adjustable lateral limits, it ensures that devices of different widths can obtain precise and stable lateral support and positioning within the mounting position 115, thereby achieving complete adaptive matching of the device's external dimensions in both length and width directions.

[0077] On the upper side (i.e., the bearing plane) of the lower frame 112 and the possible intermediate crossbeam 21, there are machined or fitted mounting grooves extending horizontally (usually perpendicular to the left and right frame directions). These grooves serve as tracks for the lateral movement of the limiting member 23.

[0078] The mounting structure 2 is equipped with a limiting member 23. This limiting member 23 has a sliding portion that matches the transverse mounting groove, allowing it to be embedded in the groove and slide freely along its extension direction. The main body of the limiting member 23 protrudes above the bearing surface, serving as a lateral barrier, support, or clamp.

[0079] Based on the actual width of the electrical component to be installed, the operator slides a limiting piece 23 along the transverse mounting groove to adjust the relative distance between it and the left frame 113 or right frame 114. When the distance is adjusted to be slightly larger than or consistent with the width of the component mounting plate, the limiting piece 23 is locked in place. The electrical component is then placed, and its side can rest against or be fixed to the positioned limiting piece 23, thereby precisely limiting its lateral position in the horizontal plane and preventing left-right swaying.

[0080] This embodiment, through the movable limiting member 23, can actively provide adjustable lateral physical constraints for devices of various widths. Whether it is a signal module as narrow as 50mm or a device as wide as close to the upper limit of the slide rail span, a tight and reliable lateral fixation can be obtained by adjusting the position of the limiting member 23, eliminating any play that may occur in the horizontal plane and greatly improving installation stability.

[0081] Furthermore, this lateral adjustment function, combined with the aforementioned height adjustment function of the crossbeam 21, allows the mounting position 115 to be customized in both vertical and lateral dimensions. This means that a single training platform can support and fix various industrial electrical components with vastly different shapes and sizes with extremely high adaptability and space utilization, thus improving physical compatibility.

[0082] In a preferred embodiment of this application, the main frame 1 encloses a plurality of mounting areas 11, which are arranged on the left and right sides of the electrical function platform 3.

[0083] The main objective of this implementation is to optimize the macroscopic layout and functional organization of the electrical training platform. Its core is to construct an overall architecture with a central electrical functional platform 3 as the control core, and multiple training operation areas symmetrically or functionally distributed on both sides. This aims to improve the equipment capacity, training parallelism, and ability to simulate complex systems of a single training platform, thereby maximizing space and resource utilization.

[0084] The electrical function platform 3 is positioned as the core control and resource supply hub of the entire training platform. The platform centrally houses the signal interface module 31 and the power supply module 32, which are usually located directly in front of the operator or in the middle of the training platform for easy observation and access by all users.

[0085] The main frame 1 is designed and constructed to enclose multiple independent mounting areas 11. These mounting areas 11 are arranged on the left and right sides of the electrical function platform 3. For example, one mounting area 11 can be constructed on the left side of the platform, and another mounting area 11 can be constructed symmetrically on the right side.

[0086] Both mounting areas 11 on the left and right sides are electrically connected to the central electrical functional platform 3 via internal wiring (power lines and signal lines). This means that the central platform can provide power and signal interaction support to the electrical components on both mounting areas 11, either uniformly or independently. Each mounting area 11 can be equipped with different combinations of devices as needed.

[0087] Compared to a single mounting area 11, the dual-sided layout allows a single training station to accommodate and operate two or more sets of electrical equipment simultaneously. This enables parallel operation on the same equipment, allowing for individual wiring, debugging, or troubleshooting exercises, effectively improving equipment utilization and training throughput.

[0088] The centralized control and decentralized operation mode places the operating interface (electrical function platform 3) in the most accessible and observable position. When trainees install and wire equipment in the mounting areas 11 on both sides, their bodies and lines of sight can naturally turn towards the object being operated, avoiding crowding and obstructed vision in a single, narrow frontal area, creating a more spacious workstation environment that is more in line with actual operating habits.

[0089] Furthermore, it allows for easy connection to the electrical function platform 3 and electrical components to form an industrial control system, reducing the length of connecting circuits. Moreover, the symmetrical or balanced layout not only makes the overall structure more balanced and stable under stress, but also gives the equipment a professional and neat appearance.

[0090] In a preferred embodiment of this application, the signal interface module 31 includes an input / output terminal block, which includes multiple digital input terminals, multiple digital output terminals, and an analog interface.

[0091] The main objective of this implementation is to provide an industrial-grade wiring platform capable of simultaneously processing digital switching signals and continuous analog signals, in order to meet the stringent requirements of real industrial electrical components for the input and output of diverse signal types, thereby supporting comprehensive practical training from simple logic verification to complex continuous control.

[0092] The core hardware of the signal interface module 31 is embodied in one or more centrally mounted input / output terminal blocks. These terminal blocks adopt a modular design commonly used in the industrial field (such as rail-mounted terminal blocks), facilitating maintenance, expansion, and identification.

[0093] The digital input terminals are configured with multiple channels (e.g., 96 status signals) for receiving switching signals. These terminals are used to connect external switches, buttons, sensor contacts, or as injection points for fault simulation signals, introducing external on / off (1 / 0) status signals into the training system for acquisition by the mounted electrical components (such as PLCs and protection devices).

[0094] The digital output terminals are also equipped with multiple terminals for outputting switching signals generated by internal relays or logic operations of connected electrical components. These terminals can drive external indicator lights (such as red / green lights), small relays, or serve as feedback signals for completed actions.

[0095] In addition to digital terminals, dedicated analog interfaces are also provided. These interfaces are typically used to connect standard voltage (e.g., 0-10V) or current (e.g., 4-20mA) signals. They are used to provide analog speed command signals to frequency converters, process variable (PV) analog signals to regulators, or to receive analog measurement signals from transmitters. This enables the training platform to simulate and process a large number of continuous process control signals in industrial settings.

[0096] A large number of clearly categorized multi-channel terminals constitute a highly flexible physical interface layer. Trainers or trainees can freely connect any input terminal to any signal source (such as a signal generator, potentiometer, or switch) and any output terminal to any indicator or actuator via external wiring. This flexibility allows the same hardware platform to simulate a near-infinite number of signal scenarios and fault types through different wiring combinations, greatly enriching the training content and depth.

[0097] In a preferred embodiment of this implementation, the electrical function platform 3 further includes a human-computer interaction module, which includes: Multiple status indicator devices, whose control terminals are electrically connected to the signal interface module 31, are used to visually display the output status of the electrical components; Multiple manual control switches, the output of which are electrically connected to the signal interface module 31, are used to provide analog input signals or control commands to the electrical components.

[0098] The main objective of this embodiment is to integrate an intuitive and convenient localized human-computer interaction layer into the training platform, based on providing a signal channel (signal interface module 31). Its core is the addition of two key components: one type directly and visually feeds back the internal state of electrical components to the operator in the form of optical signals; the other type allows the operator to inject control commands or analog signals into the system directly through physical operations without relying on external instruments, thereby greatly enhancing the interactivity and immediacy of training.

[0099] Specifically, the status indicator device includes a dual-color indicator light, and the manual control switch includes a toggle switch and / or a button.

[0100] Multiple status indicator devices, such as LED indicators and signal lights, are installed on the electrical function platform 3. The control terminal (i.e., its drive coil or circuit input terminal) of each indicator device is electrically connected to a specific output terminal of the signal interface module 31 via a wire. When a connected electrical component (such as a PLC output point or a protective relay contact) activates and energizes or connects its corresponding output terminal, the indicator light connected to that terminal will illuminate. Different colors (such as red and green) and markings visually distinguish different states, such as fault alarm, normal operation, and power-on.

[0101] Multiple manual control switches, such as buttons, selector switches, and toggle switches, are installed on the platform. The outputs (i.e., their contacts) of these switches are also connected to specific input terminals of the signal interface module 31 via wires. By pressing buttons or toggling switches, operators can directly change the on / off state or voltage level of the corresponding input terminals. These artificially generated signals are sent to the mounted electrical components through terminal blocks, simulating field button commands, mode selection signals, or fault triggering conditions.

[0102] The addition of manual control switches allows operators (trainers or trainees) to actively and purposefully change the system's input conditions. Trainers can set up a fault on-site (such as simulating an "overload" signal by toggling a switch), and trainees must then diagnose the problem based on the equipment's response and indicator light status. Trainees can also operate the switches themselves to verify the equipment's control logic. This active, interactive learning is far more profound than passive observation or simple wiring exercises, and all operations are performed within the safe voltage and isolated environment provided by the training platform, ensuring manageable risks.
