Method for monitoring centralized control system data by manufacturing execution system (MES) of coal preparation plant

Abstract

The invention discloses a method for monitoring centralized control system data by a manufacturing execution system (MES) of a coal preparation plant and relates to the technical field of computers. The method comprises the following steps of: connecting a monitoring layer network and a management layer network in an enterprise; erecting an IISweb server on the management layer network and deploying a data receiving program on the IISweb server; acquiring the required centralized control system data and sending the required centralized control system data to the IISweb server by a data acquisition program on an upper computer in the monitoring layer network; processing the received data and then storing the processed data in a shared memory space of the IISweb server by the data receiving program; allowing the content of a data display web page to change along with the data content of the shared memory space; and finally sending a request to the IISweb server by a client in the management layer network through a web browser to browse the data display web page of a centralized control system. By the method, the requirement of monitoring production process data of the coal preparation plant by an enterprise manager can be met, special human-computer interface software is not needed to be installed on each computer of managers, or special human-computer interface web page publishing software is not needed to be purchased, so that many troubles are avoided.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method for realizing data monitoring of a centralized control system by an MES of a coal preparation plant. Background technique [0002] The data monitoring of the centralized control system of the coal preparation plant is a sub-module of the MES of the coal preparation plant. The production process of the coal preparation plant is usually controlled by a centralized control system, and most of these centralized control systems are controlled by one or more host computers. The human-machine interface (HMI) software running on the computer realizes the interaction between man and the control system. Through the upper computer, the operator can monitor the production process. The HMI software running on these host computers is dedicated software, and the computers are also located in the production control room, and the upper management personnel of the enterprise can...

Problems solved by technology

[0004] Among the above two existing solutions, the disadvantages of the first solution are: (1) The client needs to install a dedicated HMI software, which causes trouble for client maintenance; (2) Each client HMI software requires separate authorization , which increases the software cost; (3) Since the HMI software of each client is directly connected to the control system, it causes hidden dangers in safety; (4) Increases the burden on the control system controller or HMI server

Compared with the first solution, the second solution has made great progress, but it also has the following disadvantages: (1) The WEB server is a dedicated server for HMI software, which is not only expensive, but also not universal. Multiple different HMI software applications are not suitable for this occasion; (2) Since it is a dedicated web server for HMI manufacturers, it has its own authority management system, which is not easy to integrate with the existing information systems of the enterprise, even if it is barely integrated , its interface style may also be incompatible with the existing information system of the enterprise
