Central heating management system, steam heating network meter reading system, intelligent heating energy-saving framework

Description :

Qingdao Hesheng Zhiyuan Automation System Co., LtdPrepaid intelligent flow display instrument is an intelligent programmable instrument with high measurement accuracy, strong functions, simple operation, and good stability. By using flow meters, pressure and temperature transmitters, or platinum resistors together, a high-precision flow testing system can be formed. Moreover, this instrument provides RS485/232 serial communication interface and USB interface for remote data acquisition and control by computer.Qingdao Zhiyuan Instrument Centralized Heating Management SystemBased on the on-site conditions of the project, our design adopts a prepaid intelligent flow display instrument to achieve measurement and transmission of prepaid steam flow meters on a flow integrator. The on-site and central display parameters include instantaneous steam flow rate, cumulative steam flow rate, steam temperature, steam pressure, and steam balance.

Central heating management system, steam heating network meter reading system, intelligent heating energy-saving frameworkPartial Function Introduction:

　　The data analysis function includes steam analysis of the sum of total table and settlement flow, steam analysis of settlement flow of each sub table and branch line, represented in the form of curves and reports, and can automatically generate pipe losses for each pipeline;

　　The system software adopts a networked design, supporting multiple network interfaces and remote browsing. After running the program on the server side, the screen will be published, and various data can be shared by other departments of the thermal power plant through the IE browser. The system has communication function with the power plant MIS system and can transmit the heat network signal to the upper information management system;

　　The GPRS steam meter reading system supports large screen projection function, which can send geographic graphics, data, curves, pipeline diagrams, etc. displayed on the computer to the large screen, making the system have good visibility;

　　The design of system software and hardware can facilitate future expansion, upgrading, and transformation; The hardware adopts modular design, which is convenient for transformation and upgrading.

　　Equipped with operation logs, it can query the operation process and modify parameters of each customer, achieve traceable and orderly supervision, and avoid operational errors that cannot be traced

Central heating management systemThe intelligent meter reading system is developed using modern scientific technology, and can directly rely on system calculations in both the reading and cost measurement stages. Therefore, the automation level of the intelligent meter reading system is much higher than that of traditional meter reading. Valve adjustment function 2: Over flow limiting function, when the flow exceeds the set value, the valve opening is automatically reduced. The small flow valve closing function automatically closes the valve when the flow rate remains below the set value for a period of time

　　Application of Qingdao STR/WEB/V2.0 Qingdao Zhiyuan Instrument Intelligent Heating System: Central heating management systemThe main application is to achieve intelligence and ensure thermal balance of heat source output. Install temperature, pressure, flow and other sensors at each heat source unit and pipeline outlet to calculate the energy consumption of each link, display information on inlet and outlet temperature, pressure, flow and other aspects. The sensors will send the collected information to the heating dispatch center to achieve real-time monitoring of various parameter information.Central heating management system, steam heating network meter reading system, intelligent heating energy-saving frameworkIn the application of heat source, it is also necessary to monitor load and weather changes, combine specific weather and load conditions, adhere to the principle of economic operation, compare the required heat with the heating amount, draw the trend curve of changes, and judge whether to start or stop the furnace. This will meet the heat needs of users without energy waste and save heating costs.
