3、 System composition

This system is designed and produced based on the actual operational standards of this subject. The system includes the following modules:

1. Hardware for low-voltage electrical work

The main equipment includes low-voltage electrician assessment devices, intelligent examination terminals, biometric devices, and instruments.

（1）Low voltage electrician assessment device

The overall body is made of steel plate, and the paint surface is matched with the current mainstream colors. The frosted spray coating process is used, and the external dimensions of the body have the characteristics of beautiful appearance, durability, small footprint, and easy mobility.

Including circuit cable connections, the electrical accessories of the electric meter are concentrated on the operation panel of the low-voltage electrician assessment device, and each question can be freely combined and arranged reasonably. The lighting circuit components and the forward and reverse electrical components of the motor on the equipment are all real components, and the operator needs to connect wires and cables according to the requirements of the actual operation during the exam.

(2) Intelligent examination terminal

Pure planar structure, ergonomic design, slim and beautiful, streamlined shape, excellent craftsmanship; Integrated design of display, touch, and PC systems;

Good scalability: flexible configuration, capable of expanding and installing various functional accessories required by customers;

High safety: aluminum alloy+sheet metal structure, no sharp edges, wear-resistant and anti-corrosion paint process;

Stable performance: advanced design concepts, strict production processes, stable and reliable product quality, low failure rate;

Easy installation: One click power on/off, eliminating on-site installation and debugging.

(3) Biometric device

When assessing operations, useshenfenzhengThe verification system performs identity confirmation. After successful verification, you can enter the assessment system. After the assessment is completed, you can upload and store your identity information and assessment results to the server for comprehensive management of the information.

（4）Instrumentation: multimeter, clamp multimeter, ground resistance tester, megohmmeter.

2. Low voltage electrician operation software system

The software design of this system is aimed at meeting the intelligent examination of low-voltage electrician operations, and the software includes training mode and assessment mode. The software system has the characteristics of reasonable design, stable and reliable operation, efficient and stable data transmission, rapid interactive operation response, simple operation, and safety and environmental protection.

Virtual scenes interact with hardware systems, with corresponding visuals and operations, accompanied by corresponding scene sound effects, lighting effects, and necessary voice and text prompts.

In training mode, the system will provide operation guidance, assessment item explanation, operation prompts, and error correction for each step in the form of sound, light, text, and icons, achieving a "teacher free" training mode.

In the assessment mode, the system does not provide prompts related to specific exam content except for necessary voice and text guidance. It relies solely on operator training and memory of exam standards to complete all assessment questions. After the assessment is completed, personal information and score information are stored and uploaded to the server for comprehensive management.

4、 Equipment functions and advantages

1. The system adopts an intelligent examination method of human-computer interaction, with real hardware equipment, stable performance, durability, and intelligent and efficient software system, which facilitates the training and examination of practical personnel;

2. System supportShenfenzheng recognition/IC card recognition method, intelligent identification of identity, intelligent allocation of examination desks, unified management of Kaosheng information;

3. The system supports the monitoring of candidates' operational behavior, and conducts intelligent scoring after the exam to reduce the influence of human factors and truly achieve the "separation of teaching and examination";

After the exam, the system automatically summarizes the exam scores of each subject, generates the final score, and uploads it to the database for archiving, making it convenient for unified management;

5. The system supports automatic submission of exam papers by candidates and automatic submission at the end of the countdown.
