Abstract

The invention discloses an open-type automatic control system solution scheme. By using the OPC XML DA technology, integration and mutual operation of multiple standards such as LonMark, BACnet and OPC can be realized. According to actual needs, an open system architecture is designed, plug and play among subsystems can be realized through a hardware and software realization method, and therefore, the problem of a lower computer communication channel can be solved in the aspect of technology updating. Then, force control configuration software is used for developing an upper computer man-computer interface, and a real-time work condition is simulated by animation. Finally, remote monitoring is realized by adopting a browser/server mode. Therefore, limitation of a building control single system and a product can be broken, economic cost can be greatly reduced, openness and interoperability of the system are realized, and convenience is brought to upgrading and maintenance of the system.

Description

LonMark based on OPC XML DA and BACnet open control system solution

Technical field

The present invention relates to a kind of economy, green, efficient, open automatic building control system framework and In System Integration Solutions.

Technical background

Constructing operation efficiency be take building automation system as basis, according to China Construction Industry Society, add up, the intelligent building of bringing into normal play at Chinese building automation system operation function only accounts for 20%-29%, so the problem that building automatic can not effectively play a role is very obvious.

Building automatic is a systems engineering, has problems in the whole life cycle of current building automation system engineering project:

(1) engineering demand location is indefinite, and system architecture design imperfection, does not have opening;

(2) in design, do not give prominence to practicality and the technology content of system, state exogenesis factory product price is high;

(3) control each subsystem in building adopts equipment and the scheme of different manufacturers, is difficult to realize interoperability and seamless integrated between multiple product, and these subsystems are integrated and to be configured to unified real-time monitoring system difficulty very large.

For above problem, reduce financial cost, improve energy efficiency, reduce a kind of opening of operational risk, the building control system architecture of interoperable and can to solve the integrated scheme of multiple subsystem be in demand.

OPC (OLE for Process Control) standard appear as the device driver that system integrator and open business provide plug and play, for the application program based on windows platform and field process, control application and set up bridge.OPC XML DA is OPC a new generation codes and standards, expanded the function of OPC, it adopts the Web service based on XML, with SOAP, as application programs, shares the standard agreement that message is packed, and between OPC client and server, by http protocol, transmits Web service.OPC XML DA has solved OPC Server can only communication in LAN (Local Area Network), can realize long-range man-machine interaction by Internet/Intranet, realize the isomery interoperability issue of application program between a plurality of platforms simultaneously, completed longitudinal information communication and system combination between automatic controlling system, monitoring, three levels of management.

Summary of the invention

For problems such as current building control systems technology barrier, opening and interoperabilities, the object of this invention is to provide a set of efficient, economy, environmental protection, can realize the automatic control system solution interconnecting between each subsystem.

The present invention realizes by following four partial contents:

1. open control system design and R&D flow process, open control system comprises host computer, slave computer and data communication network.According to user's user demand, select type and the consensus standard of equipment.

2. designed LonWorks, LonWorks/IP, BACnet/IP, MS/TP, OPC/OPC XML DA multi-protocols system integrated framework, from technological means, realized between various systems and interconnecting.

3. multi-protocols integrated architecture technology realizes.Select OPC XML DA Server management LonMark and BACnet network, realize the interoperability between OPC and LonMark and BACnet standard, use OPC middleware simultaneously, realize the conversion between OPC and OPC XMLDA.

4. Development of supervision system based on PLC and remote monitoring.Utilize ForceControl software development human-computer interaction interface, adopt B/S (browser/server) structure, user can use web browser to go to access the information such as data on Internet, text, image, animation, by setting authority, can realize remote monitoring.

Beneficial effect of the present invention is:

1. by technological means, realize interoperability between the substandard system of various protocols, than other monitoring means and approach, in opening, economy and interoperability, improve a lot, and equipment sets up convenience, cheap.

2. broken the technology barriers of triangular web and product, more flexible aspect product selection and the network architecture.
