Elevator electrical control tr--ning device,Two -drive test experimental device

1. Overall requirements

1. The model elevator has 4 floors and 4 stations. It consists of analogytic road frame, car, p--r, dictation machine, elevator door, door motor, out -of -floor call box, and m--n safety devices. The fixed setting is set on the side of the experimental table. The internal demand of analogyard frame is configured to detect floor sensors, flat layers (similar to actual elevators), etc. Its wiring terminals are cited to the inserted holes of the simulated manhole frame. The manhole frame uses metal materials as the m--n bracket, and organic glass is closed.

The device adopts a desktop structure, and the active drawer electrical board is set. Each layer drawer board is equipped with a public wiring board (bus -type wiring method, the number of bus connection points must reach 120 points), and the industrial tank ch--n connection is used between the drawer electrical board. The drawer panel connection uses a real elevator multi -core accompanying cable.

2. Model elevator drag system

The model elevator drag system is fixed on the experimental table, consisting of three -phase AC motors, reducers, fuses, heating relays, phase sequences and disconnecting relays, and AC contactors used for positive and reverse control. 380V.

3. Elevator door control system

The elevator door control system consists of the switching door control circuit and door speed adjustment circuit. The door motor is fixed on the analog manhole frame, and the DC 24V is powered. Control in relay and use independent hanging boards, which can achieve manual or automatic control of the door.

2. Requires overview

1. The assessment of the elevator electrical line disassembly tr--ning assessment is used to complete the installation of the power supply line of the elevator tr--ning room and the tr--ning equipment.

2. In each tr--ning equipment system, the following equipment including relay control method:

(1) The four -story station elevator model, which cont--ns well -channel information detection, is used to simulate the mechanical movement of the elevator car and door.

(2) The model elevator drag system is used to drive the car in the elevator model. The drag system should simulate the driver operation of a single -speed elevator. After cooperating with the inverter, the driver operation of the dual -speed elevator can be simulated.

(3) The control system of the elevator switch door control system of the relay control method can drive the elevator door with manual control and automatic control. It is used for students to conduct line connection, fault analysis and m--ntenance of the elevator door switch control system. Essence (4) AC single -speed and AC dual -speed elevator control system for relay control methods is used for students to conduct practical tr--ning such as line connection, fault analysis and m--ntenance of the relay control system of various forms of elevators.

(5) AC single -speed and AC dual -speed elevator control system, elevator switching door control system for the conversion control method are used for students to conduct line connection, programming, fault analysis and m--ntenance of various forms of elevator control systems Essence

4. 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
