I. Background
With the improvement of people's living standards, increasing emphasis on energy saving and environmental protection, urban central heating in recent years it has been developing rapidly. Increasing integration of information technology and traditional application has become the urgent needs of the public, to promote the progress and development of society. For urban heating systems, as demand improved technology and energy savings, the traditional central heating increasingly marginalized, new heating demand was growing and more sought after. With the promotion of the development of smart cities and energy savings, how safe, effective, scientifically controlled heating system has become a modern city problems need to be resolved.
Second, the system overview
Urban centralized heating system with a heat source or several point as the basis to build a heat pipe, the heat conveyed to the user through the heat pipe. Urban central heating system boiler capacity of larger, higher thermal efficiency, better economy, corresponding lower heating costs and better heating quality, and centralized emissions treatment facilities heating boilers generally are more complete, beneficial for environmental protection is an important form of urban heating in China.
Third, the system principle
Urban centralized heating system is divided into three parts, front-end data acquisition, wireless data transmission, monitoring and analysis system consisting of the rear end
1, the front end data collection: the front end of the heating unit and control the acquisition, a pressure gauge, a flow meter and the switching of the real-time status
2, wireless data transmission: the wireless communication section by taking into account information TD210 DTU using 3G / 4G wireless transmission signal, the data pass-through or to the city, county monitoring platform using a special protocol format.
3, the back-end monitoring and analysis system: data transfer after the arrival platform, view real-time data via a data terminal or a large-screen and data analysis
System Topology
Fourth, the system function
1, remote control and management
Via the Internet of Things intelligent remote monitoring and control system for centralized management of urban heating;
2, data collection and detection
Urban heating centralized control system may be a current, voltage, power and other data detection terminal online, offline, failure condition monitoring, intelligent analysis system failure;
3, multi-functional real-time alerts
Terminal failure, cable failure, power failure, open circuit, short circuit, abnormal box, cable, device state abnormality abnormality real-time alarm system;
4, integrated management functions
Data reporting, operational data analysis, data visualization, asset management and other well-integrated management, operation and maintenance management more intelligent.
5, easy to operate
User-friendly and intuitive user interface reflects the health of the entire heat transfer station. Less operating personnel, personnel training simple.
