Problems solved by technology

[0003] At present, there are the following shortcomings in the design of multi-point transmission line transmission control in my country: the speed chain adjustment mode is backward, and it cannot meet the needs of customers for flexible production in time. When customers change varieties, they need to adjust more control modes and parameters; There are many transmission divisions, and it takes a long and cumbersome time to adjust the program; there is insufficient intelligence, and when there is a problem with the transmission, it takes a long time to troubleshoot and the maintenance efficiency is low; the interface is not intuitive and friendly enough, and the man-machine interface cannot intuitively reflect the adjusted results ;Adjusting the speed chain combination requires the cooperation of professional program engineers, and the requirements for professional engineers are relatively high

Embodiment 1

[0019] Example 1: See Figure 1-3 , a system for graphically setting the transmission speed chain, which mainly includes a computer with installed human-machine interface software and programming as the upper computer, an on-site operator terminal that can also be used as a human-machine interface, and a computer equipped with a running client as an operator In the form of man-machine interface for maintenance, a programmable logic controller is used as the lower computer, and the transmission branch is composed of several frequency converters. Among them, the programmable logic controller is connected with the upper computer through Ethernet and Ethernet / Ip communication bus, and the programmable logic controller is connected with the transmission sub-driver through the Ethernet / Ip field bus. The upper computer receives the operator's speed chain change and maintenance operations through the graphical interface, and the result of the change will be logically combined in the p...

Embodiment 2

[0022] Embodiment 2, on the basis of Embodiment 1, the lower computer used in this design is a programmable logic controller, which is a digital operation electronic system specially designed for application in industrial environments. It uses a programmable memory to store instructions for performing logic operations, sequence control, timing, counting, and arithmetic operations, and controls various types of mechanical equipment or production through digital or analog input and output. process. The programmable logic controller used in the industry is already quite or close to the host of a compact computer, and its advantages in scalability and reliability make it widely used in various current industrial control fields. The PLC of this design can adopt most common PLC controller models on the market, such as s7-200, s7-300, and S7-400 series, which can be selected according to specific usage requirements and the size of the load to be matched.

[0023] Such as figure 2 ...

Embodiment 3

[0024] Embodiment 3, on the basis of embodiment 1, as image 3 Shown is the program execution circuit of the lower computer. The program execution circuit of the lower computer includes the driving roller controller Dr01, the vacuum couch roller controller Dr02, the guide roller controller Dr03, the press upper roller controller Dr04 and the press lower roller controller Dr05. The roll controller Dr01 has two SLaceNum interfaces, one of the SLaceNum interfaces of the drive roll controller Dr01 is connected to the SlvNum_O interface of the vacuum roll controller Dr02, and the other SLaceNum interface of the drive roll controller Dr01 is connected to the guide roll controller Dr03 The SlvNum_O interface and the MasterNu interface of the driving roll controller Dr01 are respectively connected to the MasterNu interface of the vacuum couch roll controller Dr02, the MasterNu interface of the guide roller controller Dr03 and the MasterNu interface of the upper press roll controller Dr...

Abstract

The invention discloses a system for graphically setting a transmission speed chain, which belongs to the technical field of automation, and comprises a man-machine interface, a lower computer and a transmission subsection, the lower computer is connected with the man-machine interface through a communication bus, the lower computer is also connected with a transmission subsection driver through a field bus, and the transmission subsection driver is connected with the man-machine interface through a communication bus. The man-machine interface receives speed chain change and maintenance operation of an operator through the graphical interface, the change result is logically combined in the programmable logic controller, the programmable logic controller controls each driver through the generated result by the field bus, and the method is convenient and efficient to set the transmission speed chain, and is high in practicability. The operation can be completed only by performing digital input setting on the man-machine interface; the speed chain setting interface is rich in content, and different control requirements under different speed chain logic combinations are met; and the speed chain of the lower computer can also be completed in a dragging manner without the operation of a professional engineer.

Description

technical field [0001] The invention relates to the technical field of automation, in particular to a system for graphically setting transmission speed chains. Background technique [0002] The multi-transmission point production line is the most commonly used control link in industrial production at present, and is widely used in the field of large-scale mechanized production and intelligent production line control. [0003] At present, there are the following shortcomings in the design of multi-point transmission line transmission control in my country: the speed chain adjustment mode is backward, and it cannot meet the needs of customers in flexible production in time. When customers change varieties, they need to adjust more control modes and parameters; There are many transmission divisions, and it takes a long and cumbersome time to adjust the program; there is insufficient intelligence, and when there is a problem with the transmission, it takes a long time to troubles...
