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 a flow meter, pressure, temperature transmitter, or platinum resistor together, a flow testing system can be formed, and this instrument provides RS485/232 serial communication interface and USB interface for remote data acquisition and control by computer.Qingdao Zhiyuan Instrument IC Card Prepaid Flow MeterBased 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.

Qingdao Hesheng Zhiyuan IC Card Prepaid Flow MeterPrinciples of Measurement Software Design:

　　The system design follows the basic principles of "mature technology, real-time and fast, 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 long-term continuous operation of software and hardware, and achieving the goal of "unmanned and few personnel 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.

It has the characteristics of simple structure, low cost, and low wiring requirements. The IC card gas sales management system consists of the following hardware: using IP network cable, server, IC card reader/writer, etc. The main software includes operating system software, database software, heat network data IC card management system software, and firewall software

This part is built and maintained by mobile operators, ensuring reliability and stability, and users do not need to invest any additional funds. The mobile data transmission system of the steam prepayment system in the park connects the station and the center through GPRS/LTE communication modules and the Internet (static IP network cable) as a medium. The IC card steam prepaid system station packages various data and transmits it to the GPRS/LTE communication module through communication lines. 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 data network location of the mobile operator. The static IP extracts the data and finally transmits it to the central server.

　　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.IC card prepaid flowmeterThe GPRS wireless data remote meter reading system is 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, reduce losses. The phenomenon of "steam (water) confusion" has taken the management of the heating network to a higher level, achieving the goal of seeking benefits from management. The 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. Curve analysis: it can compare the pressure, temperature, and instantaneous flow values of each instrument in different time periods. In order to obtain their fluctuation situation and clarify the reasons for their fluctuations, corresponding measures were formulated. In the late 1980s and early 1990s, pilot work on automated meter reading systems began. Various power supply enterprises across the country have basically established wireless power load control systems. Although their main construction purpose is to control loads, they are gradually being used for reading electricity meters for large users
