Description

Technical Field

[0001] The invention relates to the technical field of electrician professional skill appraisal equipment, in particular to an electrician professional skill level appraisal operating panel. Background Art

[0002] Against the backdrop of digital transformation and industrial upgrading, the electrician professional skills certification system is facing the dual challenges of technological iteration and changing talent demands. With the popularization of technologies such as smart manufacturing and the Industrial Internet, traditional electrician positions are gradually transforming into intelligent and complex ones, placing higher demands on practitioners' equipment integration capabilities, fault diagnosis skills, and cross-disciplinary collaboration skills. However, the current professional skills certification system still lags significantly: on the one hand, practical assessment content focuses on basic projects such as single circuit wiring and component testing, which is a generational gap from advanced technologies such as PLC control and variable frequency speed regulation that are widely used in industrial sites; on the other hand, the traditional certification model relies on the operation of physical equipment, which has problems such as high consumables consumption, high safety risks, and rigid assessment scenarios, making it difficult to meet the needs of large-scale training and dynamic capability assessment.

[0003] Specifically, the existing appraisal system has three core pain points: First, teaching content is updated slowly, and most assessment items are still based on traditional technologies such as relay control. They fail to effectively integrate knowledge in emerging fields such as industrial robots and intelligent sensing, resulting in a disconnect between skill development and industry needs. Second, the assessment format is single, lacking an assessment mechanism for complex capabilities such as system integration and process optimization, making it difficult to distinguish the technical level differences between practitioners at different levels. Third, the safety protection and energy consumption management mechanisms are imperfect. Traditional appraisal equipment does not implement functions such as low-voltage power supply in the operating area and full-area leakage monitoring, and there is a risk of accidents caused by misoperation during equipment debugging. In addition, traditional appraisal scenarios are mostly static simulations that cannot restore the dynamic complexity of the construction site, making it difficult for candidates to demonstrate their ability to respond to emergencies in the assessment. Summary of the Invention

[0004] The present invention aims to solve the above problems and thus provide an electrician professional skill level assessment operation panel that covers all levels of assessment requirements from junior workers to senior technicians and integrates industrial-grade simulation scenarios and intelligent control technologies.

[0005] The present invention solves the above problems by adopting the following technical solutions: An electrician professional skill level assessment operation panel, comprising a panel structure, a power control module, a dual-difficulty assessment system, and a safety protection module; The panel structure is divided into a power control area and an operation area. The power control area is located at the top of the panel, and the operation area is located in the cable duct area below 2 meters. The power control module includes a power box and a contactor dual control unit, a power quality detection device, and an emergency power-off device. The power control area is at least 2 meters above the operating surface. The dual-difficulty assessment system includes a semi-automatic crushing system for assessments below the technician level and a PLC control system for assessments of technicians and senior technicians; The safety protection module includes an AC36V low-voltage power supply design for the operating area, a screw motor limit power protection device, and a full-area leakage monitoring circuit.

[0006] Furthermore, the semi-automatic crushing system includes four parts: star-angle voltage reduction starting, series resistance voltage reduction starting, motor forward and reverse control and direct start motor. The system starting sequence is to start the discharge belt, main crusher and feed belt from back to front in sequence, and chain conditions are set for each link.

[0007] Furthermore, the hydraulic, lubrication and dust removal systems of the semi-automatic crushing system need to be turned on at the same time to trigger the main circuit to be energized. The feeding belt adopts a series resistor voltage reduction to start, the main crusher is equipped with a hydraulic shaft spacing adjustment mechanism and an extreme limit switch, the vibration unloading device is equipped with a manual start button, and the discharge belt adopts forward and reverse control.

[0008] Furthermore, the PLC control system includes a PLC controller, a frequency converter, a servo drive, a touch screen and an analog input and output controller.

[0009] Furthermore, the PLC control system supports multiple industrial scenarios such as simulation of traffic lights, reciprocating point control, belt transmission, lifting control and position display. Candidates can independently design control logic, and the system has free wiring functions within the scope permitted by safety regulations.

[0010] Furthermore, the power control area is equipped with voltage, current, power and frequency display devices, and the electrical quality detection device is linked with the contactor control unit to automatically cut off the output when abnormal electrical parameters are detected.

[0011] Furthermore, the operation area wiring and error correction assessment part of the safety protection module are powered by AC36V, an insulating isolation layer is set between the power control area and the operation area, and the emergency power-off device can simultaneously cut off the power box and contactor output.

[0012] Furthermore, the process design of the dual-difficulty assessment system is based on the actual process of the construction site, the semi-automatic crushing system simulates the industrial crushing production line, and the PLC control system simulates the smart factory equipment control scenario.

[0013] Furthermore, the operation panel supports the assessment requirements of five levels from junior worker to senior technician, and the assessment difficulty can be dynamically switched by changing the question board or adjusting the PLC program. The assessment items of each level cover circuit design, troubleshooting, equipment debugging and process understanding ability.
