Field acquisition equipment layer: mainly by the communication conversion module, I/O acquisition module together, and all the sensors and the monitored device to connect, guarantee the monitoring data communication between the platform and monitored the target. Field equipment layer hardware devices are modular architecture, the I/O after getting sensor data acquisition module, related system configuration, the entire sensor data matching and corresponding implementation, communication conversion module is used to ensure intelligent equipment and field control layer directly connected.
the major data center as a enterprise data information circulation and transfer, not only need to run stable, safe and reliable network computer room equipment support, and ensure that the network bandwidth capacity is higher, rich experience in system management personnel, and related services personnel conscientious. Each enterprise data center has a high requirement on equipment support, especially in the aspect of equipment safety management is more strict, also has clear specifications for equipment room temperature and humidity conditions and restrictions; In the network resources need to be able to guarantee enough network bandwidth to support network computer room equipment operation, and each part of the data center and enterprise network connection and data exchange between the branch office. Enterprise data center is the inevitable outcome of the development of modern information society, needs the powerful technical support, excellent professional talents, perfect management mechanism, as well as the safety and reliability of engine room equipment common to provide efficient services for enterprises, ensure enterprise in the fierce competition in the market environment is still in a dominant position.
Data center iot system software architecture design
Enterprise data center iot system all the business logic of the module will also be able to realize scale expansion, through the deployment of more than one server module to realize the distributed support services, and adopts double redundancy, many machine redundancy and load balancing technology to realize Internet system to improve the performance of the enterprise data center.
The enterprise data center iot system is developed according to certain rules, belong to the open system, the system modules can realize seamless integration between, through a core server to complete the system scheduling, server also all adopt the modular architecture design. For example: the database server itself belongs to the plugin structure, just as a separate function module connected to the system. However, in practice, the graphical interface, communication module, service module and strategy components adopt is a plug-in architecture, so as to realize the data layer, business layer and user interface layer of flexible extension.
Enterprise data center iot system monitoring management platform is composed of multiple subsystems and a single integrated platform, belong to run independent subsystems, each subsystem is in accordance with the unified monitoring management object, by the centralized management platform for integration. Enterprise data center iot system mainly includes seven layer structure, through the unity of the physical device layer and network layer connection to realize the network communication system. Seven layers of the enterprise data center iot system architecture design fully guarantee the system has strong stability, reliability, security and scalability.
(1) access layer. Access layer mainly includes the device access, client access, web access, SMS phone access, voice alarm system access, enterprise branch access and so on.
(2) the application layer. Application layer is mainly responsible for ensuring that the asset management system, capacity management system, alarm, report management system management system, environmental control system and expert system knowledge base of normal communication.
(3) the application support layer. Application support layer is responsible for supporting the user login, user authorization, log management, service scheme and related parameters, etc., at the same time provide basic support for the application layer.
(4) data layer. Data layer to support asset management system database, database access control management systems, parameter configuration data, report data and historical data of data management.
(5) the system layer. System layer includes system infrastructure and service two parts. System infrastructure is responsible for each server hosting, and related storage devices. System services are divided into basic services and security management two parts.
The network layer (6). Support network transmission protocol, the Ethernet transmission technology, ensure that not less than 10 mimpacte network bandwidth speed. Network layer can provide complete communications standard data interface with other systems, such as: SNMP interface, DDE interface and OPC interface and so on. Network layer sensing device information acquisition data from different systems, a distributed fieldbus network.
(7) physical device layer. Physical equipment layer requirements fieldbus anti-interference ability, has certain reliability; And be able to support the RFID, SNMP, and other commonly used standard protocols, from and Watson sensor can ensure third party equipment, such as leakage monitoring equipment, water temperature and humidity sensor, gas sensor and sensor etc.
