Data acquisition network framework and planning method

Abstract

The invention discloses a data acquisition network framework and a planning method. The framework comprises a core layer, a gathering layer, an access layer and a metering control layer. Network devices required by each layer and functions thereof are clearly known. The invention provides a large local area network topology structure where the 1000M backbone ring network is combined with 100M star-type network, and long-distance data transmission is achieved through GPRS wireless acquisition and VPN virtual channels. Through the IP / MAC address binding of a switch, the VLAN virtual network division and CSS cluster switch management technology, safety and compatibility of a data acquisition network are improved. According to the invention, reference and guidance are provided for planning and implementation of the whole solution of an energy management system.

Description

technical field [0001] The invention relates to the network field, in particular to a data acquisition network architecture and planning method. Background technique [0002] Since the "Twelfth Five-Year Plan", in response to the extensive production mode formed by large and medium-sized industrial and mining enterprises (especially heavy-polluting enterprises) that only focus on production data and ignore energy data, the state, provincial and municipal economic and information commissions, and the Ministry of Industry and Information Technology have required relevant enterprises to implement industrial Structural upgrading or transformation, implement flat and refined management of production and energy systems, and introduce relevant policies and allocate special funds to support enterprises in building energy management systems. [0003] "Energy saving, emission reduction, optimal scheduling" is the construction direction of the energy management system. According to the...

Problems solved by technology

[0004] In the process of building an energy management system, first of all, due to the lack of detailed normative acceptance standards, many construction projects have been misunderstood, and some companies or individuals have even illegally obtained special subsidy funds; secondly, most industrial and mining enterprises lack energy management system data collection Network planning, the existing network of the enterprise is basically aimed at specific objects, and only considers the needs of the local area network in the design and construction stage, lacking overall consideration; in addition, most construction units ignore the development of advanced applications, and the PLC / DCS control system interface Insufficient understanding of the importance of input, lack of overall solution design for the functional division, network security and compatibility of the data collection network
