The selected integrated management system I/A is an open distribution system with standardized control bus structure, which can be integrated with third-party control systems in different ways according to the characteristics of different weak electronic systems.

Fieldbus level interconnection: I / A series field controllers all adopt Lonworks communication specification. Because its network protocol Lontalk is completely open, it is equal to any user. Any product marked with Lonworks labeling can be implemented at the field bus level with system equipment. Interoperability, including most air conditioner manufacturers, fire manufacturers and security vendors.

Communication gateway interconnection: If the equipment of other subsystems does not meet the above standards, the information exchange with the field bus can be realized through the dedicated programmable control serial communication gateway LON SIF, and communication and linkage with other systems can be realized. At the same time, the system is required to have RS232 or serial communication port, and can provide data such as serial communication instruction set.

Control bus network layer interconnection: I / A series network controller, communication standard uses communication protocol, and has BACnet software communication interface, which can be interconnected with third-party systems in various ways.

Shared real-time database: Data bidirectional dynamic exchange through ODBC, or invoking InSQL Server real-time relational database through SQ L instruction data, thus realizing information sharing between IBM S and other systems.

Software user interface: Data exchange between subsystem application and software user interface is realized by typical data exchange mode under Windows operating system such as DDE, OLE, OPC.

Dedicated drivers: Connect to other subsystems using Wonder Ware's existing more than 200 drivers or using the Tool QIT software toolkit to develop driver-specific drivers (I/O Servers).

BACnet standard interface: The I/A system provides a BACnet standard interface over Ethernet to interconnect with other subsystems using the BACnet communication standard with a defined data format definition.

Data exchange, so that subsystem data can be summarized by writing a dedicated I/O interface program and system data such as Westinghouse access control. Jonson Controls' M ATASYS system can perform data transfer through the DDE data interface of its own monitoring software to achieve data aggregation of each subsystem.

It can also realize linkage between subsystems, such as: linkage between closed-circuit television monitoring system (CCTV) and fire alarm system, linkage between fire alarm system and smart card access control system, linkage between fire alarm system and distribution lighting and ventilation system in building automation system , CCTV and anti-theft alarm system linkage and public information database system connection, maintenance system networking and remote fault diagnosis system networking.
