Innovation experimental desk of institutional sports parameters

experimental project:

1. The assembly and simulation design experiments of the principle of the plane mechanism;

2. Experimental plan design;

3. Plan mechanism motion parameter test analysis experiment.

M--n technical features:

1. Four groups of students can be arranged at the same time. Each group can test 3 different institutions, with a total of 12 test institutions.

2. Virtual simulation teaching system

Machinery tr--ning security education virtual simulation software: This software is developed based on UNITY3D. The software is in the form of three -dimensional roaming. It can be moved by keyboard control. The direction of the mouse control lens is equipped with mechanical safety distance experiments, mechanical safety protection device experiments, mechanical safety protection design Basic assessment and experiments, the three -dimensional roaming screen uses arrows and footprint patterns to move to the experimental location. The circle around the mechanical object shows a working radius, and the experimental process is accompanied by a three -dimensional robot dialog box reminder.

A. Mechanical safety distance experiment content includes a safe distance experiment to prevent the upper and lower limbs from touching the dangerous area (the height and opening of the two fences in the inside). After choosing to enter, the GB23821-2009 "Mechanical Security to prevent the upper and lower limbs from touching the dangerous area of the dangerous area. "Safety distance" requires that the error demonstration: After the experimental process is harmed by the working radius of the human body entering the mechanical object, the blood color picture and voice reminder receive mechanical damage, return to the original position and perform the next experiment. The final step is the correct practice. Essence

This device is based on the teaching requirements of courses such as "Power System Relay Relay Protection", "Electricity Engineering", "Electricity Automation", "Microcomputer Protection of Electric Power System", and combined with the actual application and development of the microcomputer line protection experimental device. Through this experiment, students can be familiar with and master the principles of conventional electromagnetic relay protection and microcomputer protection in the power system to protect the wiring and setting test methods. The installation design is compact, integrated, and the function of the protection device is complete. It integrates multiple functions of protection, measurement, control, monitoring, and communication. This device can not only be used as a teaching experimental platform for protection of professional line protection of electricity, electrical, and automation, but also also Can be familiar with and master the hardware and software platforms that master the power communication regulations and multiple programming software. This device is also equipped with RS-485/MODBUS-RTU communication interface and upper machine monitoring software.

 

1. The safety protection system of the device

 

After the three -phase and four -line power supply is input, the output (floating ground design) is used (floating ground design). The total power supply is controlled by the three -phase key switch, and a three -phase lamp fuse is provided as the instructions and protection of the phase.

 

The control screen power supply is controlled by the contactor through the start and stop button.

 

The screen is equipped with a voltage leakage protection device and a set of current leakage leakage protection device. If there is a leakage in the inside, outside or strong electricity output of the screen, the alarm and cut off the total power supply to ensure the safety of the experiment.

 

Three -phase tone pressure device original and sub -edge have overcurrent protection technologies, which can be automatically protected by phase and lines of over -current or direct short circuit.

 

There is a timer and alarm recorder (service manager) to record the number of times of illegal use, and provide a unified standard for the assessment of students' experimental skills.
