Model: TKAPMJ-I

The design basis of this system is based on the National Coal Mine Safety Supervision Bureau's issuance of the Coal Mine Special Operation Safety Technology Practical Operation Examination Standards (Coal Safety Supervision Administration)The coal mine (No. 19, 2016)Underground electricalPractical Operation Examination Standards for Homework Safety Technology1. Can meet the practical operation assessment requirements (K1~K6) for trainees of underground electrical operations in coal mines as stipulated in the "Practical Operation Examination Standards for Safety Technology of Underground Electrical Operations in Coal Mines" formulated by the State Administration of Work Safety.

（1) Safe operation of underground low-voltage electrical equipment shutdown and power transmission

（2) Safe operation of underground wind power and methane power interlocking wiring

（3) Inspection and Setting of Underground Electrical Protection Devices for Safe Operation

（4) Safe operation of underground cable connection and fault diagnosis

（5) Safe operation of underground transformer and distribution operation

（6) Explosion proof safety inspection of underground electrical equipment

The method of generating test papers is determined byK2~K6Randomly select a subject andK1Form the test paper.

The total score of the exam isA score of 100 or above is considered qualified.

The exam time is30 Minutes. (This system provides the function of setting exam times by oneself)

This system is designed and produced based on the actual operational standards, and the overall design framework includes the following modules:Underground electrical operationsHardware system,Underground electricalHomework software system.

hardItem parameters:

Body parts:The overall body adopts1.2 The material is made of steel plate, and the paint surface adopts the current mainstream color combination, using frosted spray coating technology. The external dimensions of the body have the characteristics of beautiful appearance, durability, small footprint, and easy mobility.

Display section:adopt55Inch high-definition LCD touch display, using touch instead of mouse, breaks away from the limitations of computer operation and increases the realism of human-computer interaction. The monitor comes with a built-in audio system, and the volume can be adjusted by itself, providing clear sound effects while avoiding multiple devices being used simultaneouslyInterference occurs between each other during work.

Switch section:

K1 project: One KJZ-400A low-voltage power supply and one QJZ-200A low-voltage electromagnetic starter.

K2 project: Two low-voltage power feeders, one QJZ-2X120SF dual fan dedicated switch, one fan, one substation, one air duct sensor, one equipment on/off sensor, and one methane sensor.

Second generation shenfenzheng recognition equipmentWhen conducting assessment operations, it is necessary to use the shenfenzheng verification system for identity confirmation. After successful verification, one can enter the assessment system. After the assessment is completed, the identity information assessment results can be stored together and packaged for upload to the server for comprehensive management.

Fingerprint recognition device:Strengthen personnel identity verification by using fingerprint input and verification methods to avoid the phenomenon of others taking the exam on behalf of others.

Underground electricalControl integration module: runs efficiently and stably, with excellent performance and low power consumption.

Equipment voltage:380V national standard voltage, single power ≤ 300W. HDMI high-definition projection interface, gigabit network interface.

The equipment provides interfaces that can be connected to real switches and wind and gas sensors underground, and upload assessment results to the server.：

Extended features1: Calling function. Suitable for examination centers and units with a large number of assessments. After the assessment is completed, the next candidate will be automatically called, achieving unmanned invigilation.

Extended features2: Network face comparison function. Strengthen the prevention of substitute exams and make self requests according to the needs of the unit.

Software parameters:

This system software is designed to meetUnderground electricalFor the purpose of intelligent homework examination, the software body includes the following modules: training mode, assessment mode. Both training and assessment modes are based onUnderground electricalDesign the standards for the practical operation examination of homework safety technology.

The materials in the software scene are all based on coal minesUnderground electricianCreate on-site scenes1: Modeling, design, and production are carried out in a 1:1 ratio, strictly following the examination standards for design.

The software system has the characteristics of reasonable design, stable and reliable operation, efficient and stable data transmission, rapid interactive operation response, simple operation, 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.

The system itself meets the requirementsUnderground electricalThe basic specification requirements for homework can be carried outUnderground electricianWork environment safety inspectionSafe operation of low voltage electrical shutdown and transmission，Training and assessment on safe operation of underground wind power and methane power interlocking connections, safe operation of underground electrical protection device inspection and setting, safe operation of underground cable connection and fault diagnosis, and explosion-proof safety inspection of underground electrical equipment.

In training mode, the system will guide each step with sound, light, text, and icons, explain assessment items, provide operation prompts, correct errors, and achieveThe assessment and training model of 'teacher free'.

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 packaged and stored together and uploaded to the server for comprehensive management.

During the training and assessment process, when prompted to check the environment, use your fingers to click on the touch screen to check the checkpoints in the 3D scene.

When it is necessary to manually operate control parts such as switch buttons during training and assessment, useUnderground electrical operationsThe switch button on the platform completes the corresponding operation.

During the assessment process, if connected to the assessment terminal management system, the current assessment screen can be remotely viewed and controlled on the management platform.

The software system is connected to the assessment management platform, which enables comprehensive management of exam personnel. The management functions include personnel information collection, personnel job types, unit parameter settings, assessment arrangements, exam information storage, assessment status monitoring, exam information viewing, printing, deleting, adding, and modifying.

System Scalable Functionality1Automatically upload exam data to higher-level departments.
