Information management system and its management method, communication control system

Abstract

The invention discloses an information management system, a management method thereof and a communication control system and is used for reducing the dependence of a traditional system on an upper computer. The information management system is established between a pre-established device network and a pre-established factor network, is used for carrying out mutual conversion on messages in the device network and the factory network and comprises a scanner, a trigger and a sender. The scanner is used for scanning programmable logic controllers of devices in the device network, decoding messages carried in the scanned message reports of the device and making standard messages of a communication format with a uniform standard according to the decoded messages. The trigger is used for receiving the messages needing to be sent to the programmable logic controllers of the devices and converting the messages into device messages corresponding to the devices according to different industrial network protocols employed by the devices. The sender is used for receiving and sending the standard messages and the device messages.

Description

technical field [0001] The present invention relates to the technical field of automatic control systems, in particular to an information management system and its management method, and a communication control system. Background technique [0002] Computer Integrated Manufacturing (CIM) consists of various systems, usually Manufacturing Execution System (MES), Monotonic Rate Scheduling (Rate-Monotonic Scheduling, RMS), Statistical Process Control (SPC) ), etc., these systems need to collect a large amount of data from the equipment, due to the wide variety of equipment, limited by the pressure of communication standards, servers, etc., it is unrealistic for these systems to directly collect data from the equipment. [0003] The equipment in the prior art is transmitted to the equipment automation program (EAP) through the HSMS protocol, and the EAP interacts with the upper system (MES, RMS, SPC) through the factory network, such as figure 1 As shown, since most of the equi...

Problems solved by technology

[0002] Computer Integrated Manufacturing (CIM) consists of various systems, usually Manufacturing Execution System (MES), Monotonic Rate Scheduling (Rate-Monotonic Scheduling, RMS), Statistical Process Control (SPC) ), etc., these systems need to collect a large amount of data from the equipment, due to the wide variety of equipment, limited by the pressure of communication standards, servers, etc., it is unrealistic for these systems to directly collect data from the equipment

[0003] The equipment in the prior art is transmitted to the equipment automation program (EAP) through the HSMS protocol, and the EAP interacts with the upper system (MES, RMS, SPC) through the factory network, such as figure 1 As shown, since most of the equipment in the semiconductor industry is driven by a Programmable Logic Controller (PLC), HSMS communication often needs to add a CIM host computer to interact with the EAP system. The communication protocols between the equipment and the CIM host computer are both It is formulated by each manufacturer, such as: device 1 interacts with CIM host computer 1 through the CC-LinkIE communication protocol, device 2 interacts with CIM host computer 2 through the Ethernet / IP communication protocol, and device 3 interacts with CIM host computer 3 through the MelsecNet communication protocol For interaction, the communication formats of these communication protocols are different. If the upper system uniformly adds a function, it will be difficult to implement

[0004] To sum up, the EAP of the existing technology is under great pressure and relies heavily on the CIM host computer and EAP. If there is an abnormal problem, the risk is relatively high
