　　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 steam flow prepayment 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

Smart Heat Network Management PlatformThe system integrates the functions of automatic collection, automatic settlement, remote prepayment, and intelligent charging of energy data such as water, steam, and heat, and develops an intelligent remote prepayment system. In order to improve meter reading efficiency, meter reading performance, reduce meter reading workload, save manpower, material resources, and financial resources, and enhance the role of electricity management and inspection, the system fully utilizes its intelligence and technology to prevent steam theft and detect abnormal operating conditions

Heating network energy management system, power plant terminal, intelligent heating network management platform applicationThe mobile data transmission network is a critical part of the system, connecting the past and the future, directly determining the operational effectiveness of the entire system. This part is built and maintained by mobile operators, ensuring reliability and stability, and users do not need to invest any additional funds. The distributed energy management system mobile data transmission system connects sub stations and centers through GPRS/LTE communication modules and the Internet (static IP cables) as a medium. The smart heating network's 3D pipe network sub station packages various data and transmits it through communication lines to the GPRS/LTE communication module. The GPRS/LTE communication module encodes and processes the data, converts it into a format for public network data transmission, and sends it to the mobile operator's data network location. The static IP extracts the data and finally transmits it to the central server.

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdHeating network energy management system, power plant terminal, intelligent heating network management platform applicationSystem 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 based on different access users. The wireless meter reading system terminal 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 intelligent heating network management platform adopts RS485 bus for the low-level network of the system based on the actual situation of various meters being relatively centralized. It has the characteristics of simple structure, low cost, and low wiring requirements. It can purchase gas, recharge heat, insert cards, query, and use IC card technology with just one insert, making it easy to handle. This transforms the charging process from tedious manual meter reading and pricing to user card purchase of gas and heat, achieving automation in the collection and management of gas and heating fees. The GPRS wireless data remote meter reading system is specially designed and developed by our company to solve the above problems. It ensures the safe operation of the heating network system, facilitates the rational allocation of energy, is economical and practical, and can detect problems in a timely manner to reduce losses. The phenomenon of "confusion of gas (water)" has taken the management of the heating network to a higher level, achieving the goal of seeking benefits from management

　　Qingdao Zhiyuan Instrument Prepaid Calculator complies with the JJG1003-2016 standard and meets the trade settlement requirements of the new metering regulations for integrated calculators.

　　A. Instrument model EF-II/TCP, LCD display screen.

　　B. The instrument has an accuracy of ± 0.2% and is capable of outputting 4-20mA analog signal current (output category can be freely defined).

　　C. The function of intelligent accumulation instrument is to measure pressure, temperature, instantaneous flow rate, cumulative flow rate, frequency, differential pressure, steam balance, power outage frequency, power outage and incoming call time, daily cumulative monthly cumulative query, etc. It is programmable and can set parameters according to actual needs;

　　D. Multiple cumulative methods (lower limit flow, over flow), cumulative coefficient (percentage) can be set. It can be set that when the flow rate is less than a certain percentage of the range (such as 10%), the lower limit flow rate will be accumulated according to this fixed value. It can also be set that when the flow rate is greater than a certain percentage of the range (such as 110%), the excess flow rate will be accumulated according to the set multiplier, thus solving the problem of low flow rate in small flow and excess flow measurement and meeting the actual needs of heat network calculation.
