Description :

　　As a new generation of energy supply model,Steam metering management system, heating network energy management, intelligent heating network metering maintenanceIt is a powerful supplement to centralized energy supply systems. With the development of economy and technology, especially the active application of renewable energy, users' energy demands have begun to diversify; With the development and maturity of different energy technologies, there are increasingly more technologies to choose from. Distributed energy systems, as an open energy system, are showing a trend towards multifunctionality, including multiple energy inputs and meeting multiple energy needs of users simultaneously. People's concepts are constantly changing, and new requirements are constantly being put forward for the energy system (reliability, economy, environmental protection, sustainable development, etc.). The new Qingdao Zhiyuan Instrument Smart Heat Network Measurement can better meet these requirements and achieve multiple functional goals by selecting appropriate technologies, optimizing and integrating the system. Upload valve position, flow rate and other data, and the upper computer can set the reporting method arbitrarily. Flexible communication parameter settings: The communication address and baud rate of the prepaid controller can be set according to needs (address range: 1-128, baud rates: 2400, 4800, 9600), and the active call function: that is, data from monitoring points can be actively extracted from the server in the dispatch center at any time. The core of the RS485 wired data remote meter reading system is computer network and communication technology. Currently, the commonly used communication methods include twisted pair cables, fiber optics, and other communication methods

Qingdao Hesheng Zhiyuan Steam Metering Management SystemPrinciples 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.

Query statistics: It can query and display data for each instrument at any time during a certain period of time, making it easy to verify and query each shift. The development of technology has made automation increasingly applied in work. With the continuous development of enterprises and the increasing number of various meters, traditional manual meter reading can no longer meet the requirements of modern enterprises, and is gradually being replaced by RS485 wired data remote meter reading systems

　　The STR/WEB/V2.0 smart heating network centralized heating has the advantages of high thermal efficiency, energy saving, and low pollution, and is also a major energy-saving and environmental protection measure under the construction of green mountains and clear waters. With the increasing scope of heating, longer pipelines, and more heat users, higher requirements have been put forward for the heating management system. In response to the constantly evolving market demand, Qingdao Hesheng Company has analyzed and researched key pain points, continuously optimized and improved, and provided higher-level and more adaptable smart heating network solutions, contributing to the safety and economic operation of the heating network. At present, the values of various measuring equipment in the steam metering management system are mostly manually reported by operators on a shift by shift basis. This simple and repetitive work inevitably brings some problems, such as asynchronous 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. GPRS remote meter reading system has functions such as system maintenance, real-time monitoring, query and statistics, curve analysis, etc. Communication function: Provides RS485 communication interface, which can be connected through wired, GPRS/CDMA and other methods, using standard Modbus RTU protocol.

　　Qingdao Zhiyuan InstrumentSteam metering management systemMain functions: 1. Anti theft function, 2. Prepaid function, 3. Remote meter reading function, 4. Anti strong magnetic, 5. Anti lightning function, 6. Generate various reports, 7. Arrears, reminders, and report information prompt function, 8. Steam metering management system, heating network energy management, intelligent heating network metering and maintenance. 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. The remote meter reading system software sends commands to on-site instruments to enable data from various instruments to be transmitted through RS-485 The interface is transmitted to the corresponding data acquisition module, which automatically reads various data information from each meter according to the meter reading task issued by the management center, such as pressure, temperature, flow rate, power outage information, hour, day, month data, etc. After the prepaid box is opened, it prompts on the upper computer. After the interruption of the mains power (ac220v), the upper computer prompts for gas and heat recharge, card insertion, inquiry, and IC card technology. With just one card insertion, it is easy to handle, transforming the traditional manual meter reading and pricing into user card based gas and heat purchase. This achieves automation in the collection and management process of gas and heating fees
