Small online processing production line controlling method and system

Abstract

The invention discloses a small online processing production line controlling method and system. The method comprises the steps of accessing an HTML (Hypertext Markup Language) payment website serverof an intranet through a public network and a link address by a client to carry out online product selection and payment and realizing the conversion between the public network and the intranet through route setting of the link address and related software; analyzing a callback function of an HTML payment website of the intranet to judge the validity of payment information and screening out validpayment information to obtain ordinary string information comprising product processing data; and decomposing the ordinary string information comprising the product processing data into ASCII (American Standard Code For Information Interchange) code strings and reorganizing the decomposed ASCII code strings according to a corresponding communication protocol to obtain reorganized ASCII code strings; and converting the reorganized ASCII code strings into a ladder diagram program of a PLC (Programmable Logic Controller), sending to the PLC to complete the processing of a corresponding order according to the ladder diagram program of the PLC through the PLC of a small online processing production line, thereby realizing the real-time processing of online orders and the synchronous completionof processing tasks of automatic production lines.

Description

technical field [0001] The invention belongs to the field of automatic processing, and in particular relates to a control method and system for a small-scale online processing production line. Background technique [0002] Automatic production line refers to a form of production organization that realizes the product process by an automated machine system. Generally, PLC (programmable logic controller) is used as the core control component. In the process of operation or control, all machinery and equipment operate in a unified rhythm, and the production process is highly continuous. [0003] At this stage, the automatic production line mainly organizes various workstations to work together in the form of LAN communication, which is separated from Internet order information. The mass production efficiency is extremely high, but the product backlog is serious, and the inventory cost and sales cost are extremely high. From the perspective of professional technology, the devel...

Problems solved by technology

The consequences of this defect or deficiency are mainly reflected in the large inventory of products, the sacrifice of small batch orders and personalized orders, the very high operation and maintenance costs corresponding to the development costs of the MES system, and the inability of online configuration software to achieve real-time order response

[0005] Patent document CN201710284006.X discloses a remote control method for straw fermentation to produce biogas production, which transmits instruction signals through a wireless remote control network to control points and monitoring points for remote control through a pre-set program to realize biogas production The generated data transmission, remote control and transmission report can also solve the remote online control PLC to a certain extent, but there are certain defects: signal conversion is performed through network relays such as DTU or RTU, which is limited by the relay hardware I / O, and the signal The number of transmissions is small, the signal response efficiency is low, and it is easy to cause signal loss, and the reliability and stability cannot meet the requirements of real-time response to online orders
