State monitoring system and diagnosis method of H1000 packaging machine control network

Abstract

The invention relates to the field of state monitoring of a cigarette packaging process, and particularly relates to an online monitoring and fault diagnosis method of an H1000 packaging equipment control network. The system comprises a CAN network to EtherCAT network module, a Profibus network to EtherCAT network module, a Profinet network to EtherCAT network module, a Modbus network to EtherCAT network module, an EtherCAT network module, an EtherCAT network, an EtherCAT to real-time Ethernet module, an Ethernet network, a state acquisition module, a state analysis module, a state storage module and a state display module. The system disclosed by the invention can be compatible with a variety of industrial control network protocols, and also has expansibility and universal applicability; by adopting the system, the network state of a certain node can be diagnosed and the state of a certain module under a certain node can also be diagnosed for network flash; a timing sequence can be accurately positioned and a network breakpoint can be further identified for the network flash; and the system has the characteristics of accurate, fast and intuitive information push, diversified extension of presentation modes, and the like.

Description

technical field [0001] The invention relates to the field of state monitoring of the cigarette packaging process, in particular to an online monitoring and fault diagnosis method of the H1000 packaging equipment control network. Background technique [0002] Tobacco is an important economic force and source of taxation for the country. Tobacco taxation in my country accounts for 8% to 10% of government fiscal revenue. Due to the globalization of the tobacco industry, new laws and regulations, and major changes in the external environment, cigarette industry enterprises are facing increasingly severe competitive and social pressures. Gradually improving the quality control of cigarette products and equipment predictive maintenance is the key to achieving The effective way and inevitable trend of the goal of "controllable equipment status and efficient operation". [0003] H1000 is currently the fastest cigarette packaging unit with the most complex control system in the worl...

Problems solved by technology

As a Beckhoff control system based on PC control technology, compared with the traditional PLC control system, it has the characteristics of fast speed, multiple functions, and rich configurations, but relatively, because it uses the E-BUS bus transmission technology, compared with the traditional PLC The backplane bus transmission mode has poor stability: the main reason is that the E-BUS bus contact is disconnected, which often causes the entire control network to be disconnected, and then causes a serious crash

When there is a network failure flash, because there is no way to accurately locate the flash point information of the control network, it often needs to be diagnosed through very professional industrial control software, and there is also great difficulty in information capture, which brings great difficulties to equipment maintenance. big trouble
