    PLC-based group-controlled elevator control system design

    PLC first receives the elevator signal and flat-layer signal from the elevator, and then according to the state of these input signals, through a series of complex control programs within it, the logo of various signals The series relationship is processed in an orderly manner, and finally the switching volume control signal is sent to the DC gate control motor, frequency converter and various displays in a timely manner to control the elevator.

    PLC control replaces traditional relay control, which has become a definite development. PLC is a new automatic control device integrating computer control, automatic control technology and communication technology.

    There is a layer of the elevator control system, office telephone, optional layer selection manual, automatic functions, such as parliamentary election.

    On the basis of the general frequency converter, PLC is used to control the elevator. Through reasonable selection and design, the control level of the elevator is improved, and the comfort of elevator operation is improved, so that the elevator can achieve a more reasonable control effect.

    What are the difficulties in the design of the plc elevator control system

    1. They are all key points, no difficulties. The key is that you need to have a physical inspection program you write.Go to the large Xinhua Bookstore to the books about PLC published by Machinery Industry Press. Other publishers have almost no value.

    2. The equipment is large and has poor reliability. Slow action and few functions. It is difficult to achieve complex control, the wiring is complex, and the versatility and flexibility are poor.

    3. Hello, it's my pleasure to solve the control of the elevator for you, online, library, everywhere.

    4. Use different common points of PLC. 2) The common points of the output points of the same grade and type of voltage can be directly short-circuited. 3) The output point of the pulse signal needs to use a high-number counter, and I0.0 is usually used as the input point. 4) When assigning output terminals, the high-voltage part is usually in the front and the low-voltage part is in the back.

    5. System settingThe workload is small, the maintenance is convenient, and it is easy to transform the PLC with storage logic to replace the wiring logic, which greatly reduces the external wiring of the control equipment, greatly shortens the cycle of control system design and construction, and makes daily maintenance easier. More importantly, the same equipment changes the production after changing the program. Cheng becomes possible.

    PLC control system design of three-story elevator

    1. Design purpose and requirements of three-story elevator design (1) The elevator is called and operated by the up and down call buttons installed at the door of each floor hall. Its operation content is the direction of elevator operation. (2) The elevator car is equipped with a floor selection button S1~S3, which is used to select the floor that needs to be parked.

    2. I/O allocation on the basis of understanding the process.Carry out the software design of the PLC control system and draw functional diagrams, ladder diagrams and circuit diagrams. Design and draw process drawings, specifically including electrical panel layout drawings and wiring diagrams.

    3. It mainly involves the overall design scheme, composition and modular program design of the PLC control system of the 5-storey elevator.

    4. When the programmable logic controller is put into operation, its working process is generally divided into three stages, namely input sampling, user program execution and output refresh. Completing the above three stages is called a scanning cycle. During the whole operation, the CPU of the programmable logic controller repeats the above three stages at a certain scanning speed.

    5. "Original" three-story elevator model PLC control system design and debugging (with program annotation) [2009-3-24 8:27:00 | By: Tim ]0 Recommendation Control Requirements: 1. The system should have three working modes: driver, driverless, and firefighting.

    Single-chip computer graduation design, based on51 The design of the elevator control system of single-chip microcomputer

    and the price of single-chip microcomputer is quite cheap. If the anti-interference function is improved, it can completely replace PLC to realize the control of industrial control equipment. Of course, the single-chip microcomputer is not as targeted as the PLC, so the control system designed by the single-chip microcomputer can be constantly modified and improved with the update of the equipment to achieve the upgrade of the equipment more perfectly.

    Instruction: A number specified by the designer of the single-chip microcomputer chip, which has a strict one-to-one correspondence with our common instruction mnemonic and cannot be changed by the developer of the single-chip microcomputer.

    The system can be divided into two major parts: the elevator control module and the control panel module. 2. Bus communication interaction between the elevator control module and multiple control panels. 3. LiftControl includes motor control, elevator door control, communication with the control panel, operation logic judgment, error detection, etc. 4.
