Control mode: switch quantity/digital quantity dual control and VVVF technology; 7. Safety protection measures: with grounding protection and leakage protection functions, safety meets relevant national standards. 4. Structural composition and function The intelligent elevator consists of an elevator control cabinet and an elevator model, which can realize button control, signal control, collective selection control, human-computer dialogue and other functions. Two elevators can also be intelligently controlled in parallel (fuzzy control, expert control), elevator remote monitoring and fault diagnosis. Elevator model: It includes a drive unit, a car and counterweight device, a guide system, a door machine mechanism, a safety protection mechanism, etc. The drive unit is composed of a traction machine (with a brake, a reducer, a guide wheel, an industrial encoder), a traction wire rope and a rope head assembly; the guide system is composed of a shaft steel frame, guide r*ls, guide shoes, etc.; the door machine mechanism is composed of car doors, floor doors, door opening and closing mechanisms, safety touch panels, door covers, etc.; the safety protection mechanism is composed of overload devices, buffers, safety clamps, speed limit protection devices, etc. 1. Shaft steel frame: It adopts a steel frame structure, which is equivalent to the building to which the elevator is attached, providing support for the elevator and fixing the guide r*ls. 2. Traction machine: It is located at the top of the steel frame and is the power device of the elevator. Installed on two load-bearing beams, it m*nly consists of the following parts: (1) Motor: squirrel cage three-phase asynchronous motor, adopting variable frequency and variable voltage (VVVF) drive mode. When the elevator starts, the inverter makes the stator current frequency start from an extremely low frequency and rise to the rated frequency according to the control requirements. When decelerating, the speed is correspondingly smoothly reduced from the rated frequency to zero, achieving elevator leveling, ensuring smooth elevator operation and simulating the good comfort of a real elevator. (2) Brake: Release the brake when the elevator is powered on, and brake and keep the car position unchanged when the elevator stops. (3) Reducer: A worm gear reducer is used, which has the characteristics of high density, high efficiency and low noise. (4) Traction sheave: The rope groove is a semicircular groove, and the friction between the wire rope and the rope sheave is used to realize the movement of the car. (5) Industrial encoder: Detect the running distance of the car to achieve precise positioning. 3. Guide r*ls: There are car guide r*ls and counterweight guide r*ls to ensure the vertical movement of the car and counterweight. 4. Fully transparent car: suspended by traction wire rope, connected to counterweight through the other end of traction machine, running on guide r*l, with interlock switch installed on the car door, the elevator can only run when the door is closed. 5. Counterweight: connected to the car, the function is to balance the weight of the car. 6. Fully transparent landing door: the door is designed with door lock switch, the elevator can only start when the landing door is closed. 7. Operation box: installed on the left side of the front of the elevator model, simulating the signal input device of passengers selecting floors in the car, including: digital floor display, floor selection button, door opening and closing button, direction indicator light. 8. Elevator lock: located on the first floor of the elevator, the elevator stops at one floor after closing. 9. Call box: installed with up and down call buttons to realize external calls on each floor. 10. Overspeed safety protection: When an accident occurs in the elevator, the car is overspeeding or sliding down at high speed (such as wire rope breaking, car top pulley detaching, traction machine worm gear f*lure, motor descending speed is too high, etc.), the speed limiter will brake urgently, and drive the safety clamp to operate through the safety steel cable and connecting rod mechanism, so that the car is stuck on the guide r*l and will not fall. 11. Terminal limit switch safety protection: It is composed of a permanent magnetic sensor and provides a terminal protection switch for the car stop position signal. The sensor provides the elevator operation terminal signal. When the elevator exceeds it, the safety circuit and power supply are cut off to ensure that the elevator does not exceed the travel range.
12. Door safety touch plate: On the edge of the car door, there is a movable safety touch plate. When the door is closing, the safety touch plate contacts the passenger or obstacle, and the micro switch on the car door is touched to reopen the door to avoid accidents.
13. Door safety light curt*n protection: On the edge of the car door, there are three p*rs of detection sensors . When there is an object between the car doors, the door is always open to avoid accidents.
14. Door machine torque safety protection: The door machine uses a cert*n torque to close the car door and the hall door at the same time. When an object or a person is caught in the door, the closing torque is increased, so that the car door and the hall door are automatically reopened, thus avoiding accidents.
15. Buffer: When the elevator f*ls and causes the car or counterweight to squat (the limit switch protection f*ls), the car or counterweight hits the spring buffer, and the buffer absorbs the energy of the elevator, so that the car or counterweight is safely decelerated until it stops.
16. Intelligent human-machine: Adopt TPC7062KX touch screen, 7-inch widescreen high-definition display, resolution 800×480, 65535-color digital true color, used to display the elevator operation status and service information.
17. Information system: Through the large LED display screen, the elevator operation height, elevator operation speed, and the current operation status of the elevator on each floor are displayed in real time.
18. Video monitoring system: A network camera is configured in the car to monitor the dynamics inside the car.
Elevator electrical control cabinet: Cont*ns programmable controller, inverter, low-voltage electrical (relay, contactor, thermal relay, phase sequence protector), intelligent assessment system and other components.
1. Inverter: Mitsubishi FR-D740-1.5kW inverter.
2. Programmable controller: Adopt Siemens CPU226 host plus expansion module to control the operation status of the elevator, make logical judgment on the position of the elevator according to the call signal, and then give the operation instruction to enable the elevator to realize the functions of answering the elevator call signal and automatically closing the door.
3. Safety and door lock circuit: It is composed of relay circuit. The on and off of emergency stop and door lock switch determines whether the safety and door lock circuit is normal or not, so that the PLC can judge whether the elevator is in a safe state.
4. Assessment system: The elevator has two setting modes: manual fault setting and intelligent fault setting. The intelligent assessment system is composed of terminal and host computer software. The intelligent assessment terminal is composed of 240×128 dot matrix blue backlight LCD screen, PVC touch keyboard, single chip microcomputer , memory, network interface, etc. It can set calendar and clock, assessment time, password, and fault on a single machine. It has the functions of not losing the information of set fault and troubleshooting when power is off, recording wrong troubleshooting information, countdown display of assessment time, and alarm prompt of rem*ning assessment time. The intelligent assessment host computer software has the functions of test paper management, examination management, student information management, teacher information management, and grade management.
