Introduction to prepaid flow meters for heating networks, steam heating network terminals, and steam charging software

Description :

Meaning of smart heating and smart heating of Qingdao Hesheng Zhiyuan Automation System Co., Ltd.: In the context of building a smart city and promoting the development of "Internet plus" smart energy, the concept of smart heating came into being as an important branch of the energy industry. existingPrepaid flowmeter for heating networkThere are still some issues during operation, such as insufficient remote points, relatively outdated control technology, high energy consumption, and low energy metering. Urban heating belongs to the main content of energy conservation and emission reduction. The development of contemporary heating systems must effectively combine traditional engineering with modern data science and technology, and improve the effectiveness of energy efficiency management by predicting the operation status of the heating network. The design of heating systems is often driven by demand, and predicting the demand for heat load on the consumer side plays a crucial role in improving the overall efficiency of the heating network operation.

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdIntroduction to prepaid flow meters for heating networks, steam heating network terminals, and steam charging softwareSystem 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. d. The smart heating network valve control adopts a B/S structure, supporting 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 main operating parameters and equipment operation of the prepaid flowmeter for the heating network in the current factory production process can be collected and managed through a distributed system. The management center software has functions such as querying and displaying the remaining gas volume of the gas unit, and reporting insufficient remaining gas volume. Real time monitoring and display of user data on the electric map (including flow rate, pilot valve status, etc.). The traditional meter reading method uses a pure manual reading mode during the meter reading process, while in the later stage, the final measurement cost result is also in manual mode

Qingdao Hesheng Zhiyuan Heat Network Prepaid Flow MeterPrinciples of Measurement Software Design:

　　The system design follows the basic principles of "mature technology, real-time and fast, safe and reliable, economical and practical, easy to expand, and easy to upgrade".

　　2. The on-site measuring instrument technology meets the standard design, and adopts computer remote mode or assisted management mode.

　　3. Adopting a mature fully open, layered, and fully distributed system structure, the system configuration and equipment selection facilitate the expansion of hardware and functionality, and adapt to the rapid development of computer technology. By fully utilizing the technology in the computer field, the system performance can reach the domestic level, ensuring the safety and reliability of software and hardware, and long-term continuous operation, in order to achieve the goal of "unmanned and few people on duty".

　　4. The main network topology of the system adopts DDN network to enable communication between each station system and the central workstation, realizing data monitoring and functions. Information publishing is achieved through IE browsing through WEB Server, supporting remote access by intelligent terminals.

　　fiveIntroduction to prepaid flow meters for heating networks, steam heating network terminals, and steam charging softwareThe data transmission of high-level networks adopts fiber optic transmission with good compatibility, high reliability, fast data transmission speed, and long transmission distance. The inefficient and outdated manual management method of meter reading is susceptible to human factors, with poor real-time performance, low reliability, and low efficiency. It is difficult to detect on-site faults in a timely manner. Due to the inability to collect data from all meters at the same time, it is also difficult to measure and analyze pipe losses, and thus unable to effectively manage the heating network

Introduction to prepaid flow meters for heating networks, steam heating network terminals, and steam charging softwareIt combines computer technology, sensor technology, data communication technology, and incorporates prepaid management functions. This prepaid management system is mainly used for monitoring and managing the metering systems of various heat users in industrial parks. It uses the GPRS wireless network platform to send the parameters of each heat network user in the park to the data database on the heat network server in the heat network center through secondary instruments and wireless measurement and control communication modules. And through software, real-time monitoring of user data in the heating network is carried out, with functions such as reporting reminders, trend recording, report statistical analysis, remote recharging, and real-time control of remote electric valves for overdue payments. It assists heating network dispatch and maintenance personnel in ensuring the safety, stability, and energy-saving operation of the heating network, which is a basic prepaid system for remote meter reading in the heating network. The various meters of the smart heating network management system transmit data to the on-site collection terminal through RS485 line, and then transmit the data to the control room through independent and networked access to the system main station, avoiding external signals and network interference, ensuring the stability and security of data transmission. At the same time, it also has interfaces and redundancy with other networks. Based on the GSM network, it adopts packet switching transmission mode to overcome the disadvantages of low conversion rate and poor resource utilization of GSM circuits, and maximizes the utilization of existing GSM network resources. It has a high transmission rate, short access time, and users are online in real time and charged based on traffic, quickly reducing service costs. It is particularly suitable for sudden small traffic data transmission
