Heating prepayment control system, meter reading system of heating company, terminal of heating network prepayment system

Description :

Heating prepayment control system, meter reading system of heating company, terminal of heating network prepayment systemIt 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 IC card prepaid meter reading system has an active calling function, which means that data from monitoring points can be actively extracted from the server in the dispatch center at any time. The traditional meter reading method uses a pure manual reading mode during the meter reading process, and the final measurement cost result in the later stage is also a manual mode

　　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 prepayment control systemReport function: Automatically generate * * *, monthly reports, annual reports, and can also perform statistical reports and printing at any time. Automatic printing function can be set, displaying functions such as instantaneous flow rate, cumulative flow rate, remaining air volume, differential pressure or frequency, pressure, temperature, valve position, etc. Reminder function: When the IC card is used incorrectly (when the IC card function does not match the operation being performed), the LCD screen displays a prompt message, indicating that the operation is invalid. Device operation and parameter modification must be done with the device card inserted, which is more reliable than password protection. Data storage backup function: The system database can be stored locally, and its storage time is determined by requirements and computer configuration. GPRS wireless network provides a simple and effective communication transmission method for heating systems. The GPRS system can provide wide area wireless IP connectivity. The wireless data transmission of on-site instrument data has the advantages of fully utilizing existing networks, shortening construction periods, and reducing construction costs. Additionally, the equipment is easy to install and maintain

　　Overall, a distributed energy system with renewable energy as the mainstay and flexible diversification is a vigorously developing energy optimization supply model in this century. Various new distributed energy systems are constantly being introduced, and with the advancement of science and technology and the development of high-performance new materials, distributed energy will occupy an increasingly large proportion in the social energy structure, which will have a crucial impact on social development. The economy has entered a period of rapid development, with increasing energy demand and supply bottlenecks becoming a long-term problem. Cities must learn to manage their own energy, as this is a key link in ensuring urban development and a basic requirement for the quality of urban managers.Heating prepayment control system, meter reading system of heating company, terminal of heating network prepayment systemValve regulation function 2: Over flow limiting function, which automatically reduces the valve opening when the flow exceeds the set value. The small flow valve closing function automatically closes the valve when the flow rate remains below the set value for a period of time. The wireless remote intelligent meter reading system is built on the network of the GPRS data management center established within the enterprise, and transmits all incoming flow data to the data center through a mobile GPRS network. The wired data acquisition system is based on the RS485 bus. The RS485 wired data remote meter reading system is a system that uses modern communication and computer network technology to automatically read remote data. The IC card prepaid system consists of a prepaid control box; Explosion proof (explosion-proof) electric control valve; Card reader/writer (including recharge software); Items 1, 2, and 3 are installed at the on-site measurement point, while item 3 is installed on the office computer of the management personnel. The management center software has functions such as querying, displaying, and reporting the remaining gas volume of gas using units. Real time monitoring and display of user data electronic map (flow rate, pilot valve status, etc.)
