Description :

STR/WEB/V2.0Centralized steam supply management system, pre charging of thermal power plants, steam metering system case studyThe heating network center continuously collects various variable information (instantaneous flow rate, cumulative flow rate, pressure, temperature, compensation density, power status, valve status, power-off/power on time, prepaid steam balance, settlement balance, instrument key parameters, programming times, etc.) from various meters through a static IP transmission network, and saves these data in a universal database for generating various tables, curves, making report judgments, and reminding responsible personnel to process information through the Duanxin platform (SMS report). If required by the customer, the software provides a communication interface to provide data to the MIS system for operators to read and query the data. Prepaid Recharge Management System Currently, most gas companies sell natural gas and gas first, and then settle the gas payment every month. However, there may be some user units who find various reasons to delay the gas payment, which increases the difficulties for gas supply enterprises. The IC card gas sales management system consists of the following hardware: 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, firewall software, etc

　　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.Centralized steam supply management system, pre charging of thermal power plants, steam metering system case studyData management function: Data browsing: historical data can be browsed separately and can be deleted, queried, and printed. For example, information stored in the database can be browsed, such as meter readings, statistical data, curve data, event data, etc., and these data can be exported into corresponding reports for printing. If there is a gas flow meter on site, we do not need to use our flow integrator. Only the on-site flow meter needs to have RS485 communication function. Based on the communication protocol of the meter, we have developed communication software and directly connected it to the IC card controller with RS485 cable, The 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 to 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. Currently, the values of various measuring devices are mostly manually reported by operators on a shift by shift basis. 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

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdCentralized steam supply management systemSystem Introduction:

　　1. Establishment of a prepaid steam metering management center;

　　2. Installation, commissioning, and data transmission of 100 sets of prepaid steam metering equipment;

　　3. 100 remote metering points will be opened for prepayment of steam on the power plant's external network, with N metering points used in the first phase. The excess will be reserved for future expansion;

　　4. According to the steam parameters provided by Party A, the rated pressure is 2.5Mpa, the upper temperature limit is 320 ℃, the working pressure is 1.2Mpa, and the working temperature is 300 ℃. This data is an important parameter for us to choose a flow meter.

　　5. The intelligent heating network valve control GPRS meter reading system is connected to the Internet network and communicates with the main station computer through the GPRS network. The user's data is processed and protocol encapsulated by the GPRS module before being sent out. It is then received by the GPRS receiving module and transmitted to the main station via the Internet network, achieving real-time online connection between the user's energy consumption data and the main station. Valve adjustment 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

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdCentralized steam supply management system, pre charging of thermal power plants, steam metering system case studyDesign 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 IC card prepaid control terminal 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.
