Film-winding packaging machine control method and system based on single-chip microcomputer

Abstract

The invention discloses a film-winding packaging machine control method and system based on a single-chip microcomputer, and the method comprises the steps that a touch screen and the single-chip microcomputer carry out initialization after power-on; the touch screen requests the single-chip microcomputer for values of working parameters, working state and an AD value of a pressure sensor in a mode of 485 communication; the single-chip microcomputer communicates with an EEPROM data storage module through simulating an I2C protocol through software, reads the data of a corresponding data region, and returns the data to the touch screen; the single-chip microcomputer receives a start instruction after a start button is touched, and operates equipment according to the working parameters which are stored in an EEPROM data storage. During operation, a chassis motor, a lifting motor and a film-winding motor are driven by a frequency converter to operate, and the single-chip microcomputer employs a Modbus protocol and a frequency converter for communication so as to control the start, stop and rotating speed of motors. The method and system can achieve a purpose that the replacement of a PLC module is controlled through the single-chip microcomputer, and greatly reduces the development cost of a product.

Description

technical field [0001] The invention relates to a film wrapping machine, in particular to a control method and system for a film wrapping machine based on a single-chip microcomputer. Background technique [0002] In the field of industrial automation, including the film wrapping machine industry, the PLC module used by the general main control board, due to the high price of the PLC module, increases the cost of product development. In addition, the market competition is fierce, and the product price is too high, which will lose market competitiveness. If the profit margin of the product is small, the enterprise may not be able to survive. This patent aims to realize the replacement of PLC modules by single-chip microcomputer control, thereby reducing product development costs. Contents of the invention [0003] In order to solve the problems of the prior art, the present invention provides a single-chip microcomputer-based film wrapping machine control method and system...
