Description :

Qingdao Hesheng Zhiyuan Automation System Co., LtdHeating network energy management system, external network steam metering and charging, GPRS remote meter reading instrumentSystem functions:

　　a. Can query historical data of any hot user, any parameter, and any time period, and support the export and printing functions of statistical reports and analysis curves; Rich report customization printing and archiving functions, which can print hot user daily, monthly, and steam consumption detail reports, parent pipe daily, monthly, and summary reports, and can be archived as EXCEL format files (*. xls). b. Hot user management data system, including flow rate, pressure, temperature, upper and lower limit report settings, current operating parameters of instruments, unit price, special policies, responsible person information, etc., to prevent users from modifying settings; c. Access control function: Operators need to apply for a login name with their personal ID when logging in (non ID cannot be applied for), and achieve real name login; After entering the password and passing identity verification, the system can enter. The system defines access permissions according to different access users. The IC card prepaid management system adopts a B/S structure and supports intelligent terminals with internet access functions to access, enabling the operation of the heating network anytime, anywhere and achieving mobile office; e. Geographical distribution map of heating network users and routing map of heating network pipelines, which can be drawn according to the needs of the network and marked with steam flow direction (green line in the figure), locate the coordinate points of heating network users, and display the pipeline distance between heating customers and heat sources;

　　f. The energy management system of the heating network has gradually established remote meter reading and system in cities, and the use of technological means to improve the measurement and management level of hot water, steam, tap water, gas, etc. has become a consensus among people. Currently, the values of various measuring equipment are mostly manually read and reported by operators every shift. This simple and repetitive work inevitably brings some problems, such as unsynchronized meter reading, large human error, and high labor intensity. Manual meter reading has become an obstacle to the automation and informatization of data management in power plants. Therefore, the application of RS485 wired data remote meter reading system is necessary. Data management function: data browsing: can browse historical data separately and delete, query, and print these data, such as browsing information stored in the database: meter readings, statistical data, curve data, event data, etc., and can export these data to generate corresponding reports for printing

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdHeating network energy management system, external network steam metering and charging, GPRS remote meter reading instrumentDesign principle:

　　1. The operator workstation in the center adopts a B/S structure, supporting remote access to intelligent and other intelligent terminals (with internet access). Using the above technologies, modular and structured application software suitable for the actual needs of this project is developed, making the system more adaptable to the increase in functionality and scale expansion; The software adopts a mature standardized Chinese system, with a user-friendly interface and easy operation. The displayed images and printed files are clear and eye-catching.

　　2. The system has high reliability, strong resistance, high availability, and good maintainability.

　　3. The intelligent heating network inspection is highly reliable and will not affect the normal operation of on-site measuring equipment due to local faults.

　　4. The measurement system software includes four major parts: computer operating system software, database software, tool software, and application software. The application software is based on the JA framework and adopts a modular (functional module) structure, with high development efficiency, easy maintenance, and strong flexibility, allowing end users to truly open up without writing statement instruction programs.

　　With the trend of informationization and intelligence development in the heating network, the existing heating network collection system is no longer suitable for new intelligent management requirements. It is necessary to upgrade and add functions to the existing hardware and software systems to build a smart heating network management system.Heating Network Energy Management SystemThe permissions of the sub centers are limited to data monitoring and do not allow downward operations, ensuring the security of the system. The data of each sub center in the main center is fully synchronized and displayed in real time. The valve closing function: when the purchased steam volume is used up, the valve will automatically close. The valve closing action can be set according to the actual situation, such as closing 50%, 40%, or 30%, and the specific value is set by the user themselves. Power outage protection function: The original data can be saved for ten years during a power outage. System security permission setting function: Permission setting provides complete security authentication, and users cannot enter the system. Legitimate users can perform corresponding operations according to their permissions
