Intelligent control system for production conveying line

Abstract

The invention discloses an intelligent control system for a production conveying line. The intelligent control system comprises a switch and at least one production conveying line control subsystem. The production conveying line control subsystem is used for carrying out signal transceiving and processing of a local production conveying line and control on operation of a motor. The production conveying line control subsystem comprises a controller, a human-computer interface, at least one motor and at least one sensor. The controller and the human-computer interface are connected with the switch through a local area network. The switch is used for exchanging data transmitted between the controller and the human-computer interface in the production conveying line control subsystem. By the adoption of the intelligent control system, the occupied space of a frequency converter can be effectively reduced; the wiring quantity of components such as the motor, the frequency converter, the sensor and the like is reduced; the data interaction between production conveying lines is enhanced; and the information level of collection and monitoring of production data and equipment information isimproved.

Description

technical field [0001] The invention relates to a production conveying line control technology, in particular to an intelligent control system for a production conveying line. Background technique [0002] Production conveyor lines have been widely used in modern manufacturing. The production conveyor line divides production activities into multiple standardized processes, and then repeats operations by machines or production workers to produce products of the same specification on a large scale. In recent years, with the increasing development of industrial technology, industrial manufacturing has paid more and more attention to intelligence and informatization. The main components of the existing mainstream conveyor line system are human machine interface (Human Machine Interface, HMI for short), programmable logic controller (Programming Logical Controller, PLC for short), frequency converter, asynchronous geared motor, and detection sensors. The running speed of the mo...

Problems solved by technology

[0005] Large amount of wiring and complex wiring: the drive power of each motor needs to be wired from the control cabinet through cables, and each sensor needs to be separately wired to the 24VDC power supply of the control cabinet and PLC input points. Each medium-sized transmission line needs to be connected to hundreds of Drive cables and signal cables, these connections consume a lot of wire and man-hours, and also increase the failure rate of the transmission line, which brings a lot of inconvenience to installation and debugging;

[0006] The interaction signals between production conveyor lines are single: the interaction signals between different production conveyor lines are mostly interlocking signals between equipment, and the transmission of these signals needs to be converted through intermediate relays, and there is not much interaction of production data between production conveyor lines;

[0007] The collection of production data and equipment information is inconvenient: the degree of informatization of the production conveyor line is low, and most of the production data is stored locally with a small storage capacity. It needs to be transcribed and summarized manually on site, and it is impossible to remotely understand the real-time production information on site through the network.
