The Development Of Monitoring Service And Platform Configuration For Building Electrical Monitoring System

Intelligent building makes people’s life more safe, convenient, comfortable and energy-saving. Building electrical monitoring system is an important part of intelligent building. The building electrical control system is designed based on the independently developed fieldbus technology, network node module, gateway and monitoring terminal. In this master thesis, a building electrical monitoring service platform and a functional configuration platform are developed for the building electrical control system. The monitoring service platform is used to support the monitoring protocol transferring between TCP/IP and local network control protocol, and the functional configuration platform is used to reconfigure the functionality of the network node module when some of the local inputs are changed.The monitoring system is divided into three layers, or application layer, communication interface layer and local monitoring network layer. The application layer contains configuration platform and monitoring terminal platform, and the communication interface layer includes monitor server platform and gateway module. The local monitoring network layer is based on L-N fieldbus with some network node modules connected. Monitoring service platform connects the monitoring application platform and the gateway module. In our system, the monitoring service platform implements communication, protocol conversion, data display and storage, manual instruction edit and so on. Every node module in the local network supports electrical I/O interfaces, such as silicon controlled rectifier, relays, switch, sensor, analog/digital inputs and so on. Each I/O interface component contains two or three trigger modes. The main module executes some control instructions when a component is triggered. These instructions are preconfigured by the developed configuration platform. The configuration platform implements such as user identification, message generation and display, configuration for basic attributes, general commons and special commands.The monitoring service platform and configuration platform are developed by using Visual Studio edition 2008 which supports Microsoft foundation class (MFC), object-oriented programming technology and multi-threading, socket based TCP/IP communication technology. Dialog view based architecture is used for designing interface of the monitoring service platform, and single document view architecture is adopted for implementing the configuration platform interface. To meet the communication requirement of this system, the communication protocols are formulated, which consist of the text-based protocol and the binary-code-based protocol. They defines strict packet attributes, operation objectives, operation mode, additional parameters and so on, which are used to implement I/O controlling, state getting and reconfiguration for electric equipment through the defined instruction message, configuration message, inquiry message and feedback message.Finally, functional test and field debugging for the developed software modules and the whole platform are implemented. The modules such as communication, configuration, message packet generation and conversion are tested. The final testing and system demonstration indicate that the monitor service platform and the configuration platform designed in this thesis can support the I/O remote monitoring for electrical equipment, monitoring functional configuration for network nodes successfully.
