It adopts the overall design of the frame steel square tube frame structure. The front uses transparent organic glass panels, and the low -voltage electrical, PLC, variable frequency speed adjustment, smart human -machine, sensing detection, video monitoring, and intelligent assessment system equal to equal One -one, realize the complex switching control and timing logic control of smart elevators. Through the operation of this device, students can evaluate the comprehensive ability of students to master the installation and m--ntenance of smart elevators, such as the installation of the elevator's hopping box, the installation of the well -track information system, the adjustment of the flat -layer switch detection position, the adjustment of the door machine mechanism, the electrical control cabinet of the electrical control cabinet, the electrical control cabinet Device installation, wiring, inverter parameter settings, PLC programming and debugging, elevator group control function debugging, elevator f--lure elimination, operation and m--ntenance, etc. In addition to meeting professional tr--ning teaching, you can also carry out skill assessment and professional skills competition.

2. Product characteristics

1. The equipment height simulation is designed according to the actual elevator reduction ratio, including all elements of the elevator. The elevator is four layers and a height of 3 meters.

2. Fully transparent structure design, the internal structure and operation process of the elevator are clear at a glance. Let students understand and understand the structure of the elevator very intuitive and thoroughly.

3. The device is a two -seater and four -layer group control elevator. Each elevator system is controlled by a PLC. The PLC is switched through the 485 communication module. Through the tr--ning of this device, students can not only practice single elevator control, improve the detection and exclusion ability of faults, but also learn elevator group control technology.

4. Smart elevators have two setting methods: mechanical f--lure settings and smart f--lure settings to facilitate user operation.

I. Overview

Microcomputer device human -machine interaction interface adopts large -capacity, high and clear 7 -inch color touch screen, which can display the voltage, current, frequency, non -meritority and other electrical parameters of the system in real time. Interactive, the menu Chinese shows, and the graphic and text is full of graphics.

 

6. Micro -machine device adopts DSP+CPLD high -end chip: In order to meet the needs of the experimental platform control system, high -performance, high -precision industrial control 32 -bit fixed -point DSP controller is used to achieve data processing with software. Meet the requirements of large computing quantities and high computing speed; CPLD is a complex programmable logic device that uses computer -assisted design technology to configure the designed data file into the static data memory (SPAM) inside the chip. Sex can flexibly configure the hardware logic circuit, reduce the space and complexity of the PCB board, and improve the reliability of operation. The DSP+CPLD is combined and applied to the experimental platform control, and the improved control algorithm and hardware structure are improved, so that the entire control system meets the requirements of fastness, accuracy and stability.

 

7. Artificial intelligence and adaptive PID control: In order to achieve accurate, stable, and secure adjustment of the speed and output voltage of the generator, eliminate the oscillating phenomenon in the control process, this device combines the conventional PID controller with the self -reliance algorithm combined and utilized The artificial intelligence system automatically adjusts the PID parameter at every moment of the system state change, so that the control process is always in a ** state.
