GM Electrician Electronic Training Desk

Students of electrical, electronics, and electrical dragging experiments can obviously understand the principles of line structure and experimental.

 

The purpose of teaching, electronics, and electrical dragging laboratory installations is to enable students to be systematically educated and tr--ned in terms of basic knowledge, basic methods and basic skills of students' basic experiments, and deepen and consolidate the basic concepts and regular understanding of the circuit. Cultivate students with preliminary experimental ability, good experimental habits, and rigorous scientific attitude and style, and lay a good foundation for subsequent experimental courses and scientific research work engaged in the basic aspects of circuit foundation.

 

1. The characteristics of the product:

 

General Electric Electronics Technology and Electric Drague Experimental Design Puts have relatively complete safety protection measures, more complete functions (see the introduction of the experimental desk structure for det--ls). The center of the experimental table is equipped with a universal nine -hole ** plug -in board. The m--n body of the nine -hole ** plug -in board is made of ABS injection. The surface is covered with nine -hole into a group of pussy connectors. Copper nine -hole integration embedded. The weak electric module in the experiment must be based on the independent packaging transparent component box as a single module. The unified component box can be freely built with the nine -hole ** plug -in board. Okay, the lid printing circuit diagram is scratch -resistant and wear -resistant, and the symbols are beautiful and clear. The component box body and the lid adopt a more scientific card -type structure, which is convenient for m--ntenance and disassembly. The components are placed under the experimental table to store the cabinet, which greatly improves the level of management, planned the degree, and greatly reduces the preparation of teachers' experiment.

 

2. Electrician electronic technology and power drag experimental device structure

 

General Electric Electrical Electronic Technology and Electric Drague Experiment Power are controlled by the power control box, the experimental table (equipped with the nine -hole ** plug -in board), the electrical control experimental hanging box, the experimental hanging stent, the mobile low cabinet, the oscilloscope frame, the transparent innovation experimental module, the transparent innovation experimental module, the transparent innovation experimental module, Student stools and other composition. Experimental device brackets and experimental tables can be combined and dismantled. The bracket is integrated with the table foot, aluminum alloy structure; electrical control experimental hanging and various experimental modules can freely combine experiments according to experimental needs.

I. Overview

The tr--ning device consists of two parts of the hardware and software. Among them, the hardware includes the unit, the smart instrument, and the DCS control unit; Composition of engineering mathematics software.

Signal interface panel: The instrument signal and electrical signal in the control object are transferred to the signal wiring board, which provides sensor detection and actuator control signal interfaces such as *, AO, DO, etc., facilitating the connection to form a different control system. Different wiring between the experimental board and the signal board is performed through a secure -type plug -in wire to complete various experiments in the process.

System networks are divided into three levels: monitoring network, system network and control network. Monitoring network layers to realize the interconnection of engineer stations, operator stations, ** computing stations and system servers. Company, control the network layer to realize the communication station and the process of on -site control stations and processes.

Second, configuration and function

(1) The overall structure of the system

1. The system network architecture is composed of the management network (MNET), system network (SNET), and control network (CNET). The management network is an optional network layer, which is used to communicate with factory -level production management systems such as MES and third -party management software. It can also implement security information publishing through Internet, and realize data management and sharing.

2. System network connection engineer stations, operator stations, historical stations and control stations and other system nodes, support P-TO-P (peer network), C/S (client/server), P-TO-P and C /S (mixed) three network structures can quickly build a high -speed redundant network of star, ring or bus -type topology, complies with IEEE802.3 and IEEE802.3U standards, and 100/1000Mbps adapt.
