An OPC data acquisition and monitoring intelligent terminal based on td-lte

Abstract

The invention discloses a TD-LTE-based OPC data collection and monitoring intelligent terminal, which comprises a TD-LTE communication management module, an OPC data server, an OPC client and an access control module. TD-LTE-based OPC data acquisition and monitoring intelligent terminal can establish a reliable data acquisition and control instruction transmission channel between the upper management information system and the lower monitoring equipment, and adopt standardized interfaces and wireless communication automatic networking functions to realize enterprise information Integrated management and real-time control of industrial processes, with distributed monitoring and centralized data management capabilities, fast data transmission, portable and mobile, suitable for most field data controlled by OPC servers developed based on OPC‑DA specifications Acquisition equipment not only has an open and efficient communication mechanism, but also provides a consistent solution for the monitoring system to access field equipment data.

Description

technical field [0001] The invention relates to the technical field of data collection terminals, in particular to a TD-LTE-based OPC data collection and monitoring intelligent terminal. Background technique [0002] Using various remote intelligent monitoring technologies to realize the information integration of industrial systems or production processes, and to improve the combination level of enterprise information management and production process automation can not only greatly improve production efficiency, but also provide a broad scope for the development of intelligent monitoring technology. application field. [0003] The remote data acquisition and monitoring terminal is the basic equipment of the intelligent monitoring system. At present, it is mainly based on the embedded system application, and realizes the control unit, I / O input unit, data acquisition unit, GPIO unit and communication unit (Ethernet, GPRS, serial port, etc.) and other integrated integration...

AI Technical Summary

Problems solved by technology

The main defects of the existing terminal technology are: (1) The remote transmission of data is mainly based on wired network communication, the system deployment is not convenient, the construction and maintenance costs are high, and the mobile access technology such as GPRS is used, and the data transmission capacity is low , the reliability is poor, the delay is long, and it cannot meet the real-time transmission requirements of a large amount of data; (2) the openness and compatibility of the monitoring data protocol are poor, and the monitoring system is very dependent on the underlying acquisition equipment, so it is difficult to adapt to large-scale Integration of Scale Monitoring and Information Management System

(3) The data terminal is mainly based on local data collection, bound to the data forwarding function, the application structure is too simple, only suitable for statically configured monitoring network, and the scalability is relatively poor
