Product Description

1. Introduction to the four-story elevator training model
The system consists of two parts: mechanical transmission and electrical control: the mechanical part controls the opening and closing of the door and the up and down movement of the car; the control part is controlled by the PLC to control various function switches and indicator lights to complete the various actions of the elevator.
The electrical control system of the elevator adopts Siemens PLC intelligent control (Mitsubishi can also be used), with functions such as automatic leveling, automatic door closing, collective selection control, forward response to call signals inside and outside the car, direct driving, protection of elevator safe operation, lighting, etc. . And it has the characteristics of reliable performance, stable operation, simple operation, low energy consumption and easy teaching. This module can extend the MCU interface, that is to say, it can also be controlled by the MCU, which realizes a system of multiple teaching purposes.
System composition: Elevator model includes lifting motor, limit switch, guide rail, accompanying cable, hall door, call button, floor display device, car, door opening and closing mechanism, leveling device, floor lamp in the car, car lighting, control System etc.

2. The main components of the elevator
1. Pulling machine: The pulling machine is the driving device of the elevator. It mainly includes:  Drive motor  Pulling pulley: The rope on the pulling machine is called the pulling pulley. At both ends, the car and the counterweight are respectively suspended by the drag rope, and the lift of the car is realized by the static friction between the drag rope and the groove of the drag wheel. Guide wheel: In order to ensure that the car end and the counterweight end draw ropes are perpendicular to the car and the counterweight, and remain parallel, and to ensure that the lead pulley has a large enough wrap angle, a guide wheel (commonly known as anti- Rope wheel).
2. Car: The car is composed of car frame and car body. The car has different specifications and appearance designs due to different uses.
3. Guide rail: The guide rail is fixed on the wall of the hoistway through the guide rail bracket. The position of the guide rail defines the position of the car and the counterweight. The guide rail is the track that the car runs up and down.
4. Counterweight device: The counterweight device consists of a counterweight wheel, a counterweight frame, a counterweight mound, and a lead rope. The counterweight is balanced against the car.
5. Limit switch: This device can be installed on the car or near the upper and lower end stations of the elevator shaft. When the car runs beyond the end station, it is a safety device for cutting off the power supply.
6. Elevator call button: In this teaching elevator, the elevator call button is installed in the upper left corner of the elevator model panel, used to specify the floor you want to reach, and can display the elevator car's running position and direction.
7. Floor display window: It is installed on the right side of the elevator model panel. By operating the buttons with up or down arrows, the car can reach your floor and display the elevator car running position.

3. Principle of elevator control
1. This teaching elevator is an automatic elevator model operated by passengers themselves. The floor display window is on the right side of the elevator, and there are up and down call buttons (ie, up and down floor buttons) on the top and bottom floors respectively, and up and down call buttons are set on other floors. The elevator call button in the upper left corner is equipped with corresponding instruction buttons equal to the number of floors. When the passenger entering the car presses the command button, the command signal is registered, and when the passenger waiting outside the door presses the upper and lower floor buttons, this signal is registered. In the process of upward movement, the elevator will stop one by one according to the registered command signal and the upward call signal until the highest landing of the signal registration, and then run down in the reverse direction, and then stop at the corresponding downward command signal and call signal in sequence. Every time it stops, the elevator will automatically decelerate, level and open the door. After the passengers enter and exit the car, they close the door by themselves until the last task is completed. If the signal reappears, the elevator selects the direction according to the signal position to start running by itself. If there is no work instruction, the car stays on the last floor that it stops.
2. Automatic door opening and closing: When the elevator is leveling slowly, the door machine will act after the leveling delay, and the door will open automatically. When the door is in place, the door machine will switch in place and the door machine will stop. After the elevator opens the door on the floor, after a delay of about 2 seconds, the door motor rotates in the door closing direction. When the door is fully closed, the fully closed door switch will act and the door machine will stop. But when the passenger presses the close button, the elevator closes immediately. When the car stops at a certain floor and the door is closed, press the call button of that floor and the door will be opened.
3. Starting, accelerating and running at full speed of the elevator
The starting of the elevator is controlled by PLC, frequency converter and electromagnetic brake. First, the PLC determines the rising (Q1.4 port output) or falling (Q1.5 port output) command according to the command signal, and then transmits the rising or falling and speed control commands to the inverter's corresponding forward or reverse and preset speed. And give the opening command to the electromagnetic brake to release the brake. The inverter controls the start, acceleration and full speed operation of the elevator through the internal preset speed.

4. Introduction to experimental procedures
(I) Experimental purpose
1. Understand the basic structure and operation principle of elevator;
2. Master the use of remote I/O communication network system to realize the PLC control of the elevator.
3. Master the basic principles of PLC control, master the principles and use of three-phase asynchronous motors, frequency converters, sensors (for leveling positioning), and rotary encoders (generating high-speed counting pulses).
(Ii) Experimental content
1. Experimental steps and debugging methods
(1) Download the program of the four-floor elevator training model to the PLC, connect the PLC input and output lines to the panel according to the wiring diagram, and power on after checking the wiring.
 (2) After setting the programmable controller to RUN, if the elevator car stays on the first floor. Press the first floor upstairs button under the "floor display window", which means you want to take the elevator. If the car is not on the first floor, when you press the first floor upstairs button on the first floor, the car will first descend to its position Open the door again. If you are on the first floor and the elevator car door opens, press the floor you want to reach from the buttons under "Elevator Call Button", the floor indicator will light up, and press the door close button to close the elevator door. The car starts to rise, and the floor where the elevator car is at that time will be displayed in the "floor display window". When the designated floor is reached, the car door will open and then automatically close after a while.
(3) In other buildings, you can press the upstairs or downstairs button, the elevator car will reach the floor, and then open the car door, then press the floor you want to reach, and press the door close button, the elevator car door closes, the elevator The car starts to ascend or descend. After reaching the designated floor, the car door opens and then automatically closes after a while.
(4) During the operation of the elevator car, when the car is ascending (or descending), the exterior call signals that descend (or ascend) in the opposite direction will respond in order to eliminate the call signals. For example, if the elevator car is on the first floor and is ascending to the fourth floor, if there is a three-story up button for calling on the third floor and a second-floor down button for calling, the elevator car will first respond to the three-story up button during the ascent process. , Eliminate the three-layer calling signal. Then respond to the four-floor internal call button, and finally descend to the second floor to respond to the second-floor down button, but only the elevator car door of the last responding floor will open. When the elevator stops after executing the last instruction, if there are passengers entering the car at this time, the instruction signal can give priority to determine the elevator running direction.
(5) When the elevator is not leveling or running, neither the door open button nor the door close button work. After leveling and the elevator car stops running, press the door open button to open the car door, and press the door close button to close the car door.
