Method and device for controlling intelligent edge pulling machine system

Abstract

The invention discloses a method and a device for controlling an intelligent edge pulling machine system. The method comprises the following steps: receiving data of a plurality of edge pulling machines in a wireless transmission mode and sending the data to an upper computer by a CPU in a main control cabinet; when the data is sent to the CPU by each edge pulling machine, in staggered sending periods, sending the data in a time-sharing mode in a data frame, in the current period, comparing the data of the current edge pulling machine with the data sent to the CPU in the previous period of thecurrent period, marking parts with the same data, only sending the corresponding marks when the data is sent, directly sending the corresponding data of the parts with different data, after the datais sent to the CPU, and calling the data of the previous period of the current period corresponding to the marks in the parts with the same data. The method has the advantages that communication cables do not need to be arranged, the cost is low, and faults can be quickly removed by changing the data transmission mode and the communication mode.

Description

technical field [0001] The present invention relates to the field of network base station construction, and more specifically relates to a control method and device for an intelligent edge-drawing machine system. Background technique [0002] The edge pulling machine is one of the main equipments of float glass production, it plays an important role in throttling, thinning, accumulating thickness and controlling the direction of the original plate. Its principle is to rely on the edge pulley at the front end of the edge puller to pull the glass ribbon with a certain viscosity floating on the liquid surface of the tin bath to move forward. Inclination angle, etc., to control the thickness of the glass ribbon and stabilize the width of the glass ribbon. The quality of the edge machine control directly affects the output and quality of its glass. At the present stage, each pair of edge machines independently controls field devices, and uses two methods of Ethernet communicatio...

Problems solved by technology

However, all the control signals on site are collected and sent to remote control cabinets through control cables, and are sent to field devices through information processing through the PLC in each control cabinet. The distance between them is relatively long, and a large number of signals are transmitted and collected through cables. Cause mutual interference, and use a large number of cable network lines, the cost is high

The information data is collected and summarized on the upper computer, and the overall information status can only be seen through this upper computer. When production operations and equipment failures occur at the same time, it is not conducive to both at the same time, and often the failures cannot be handled quickly.

Control cable, communication cable and CPU use cost are high, failure rate is high, interference rate is high, intelligence level is low

The use of the operation station is single, and the equipment cannot be operated at the same time when inspecting and troubleshooting
