　　Qingdao Hesheng Smart Heating Network Heating User Management: 1. Basic information management of heating users, including user name, number, person, method, pipe diameter and wall thickness, metering equipment form (vortex street, orifice plate, etc.), declared steam consumption, commonly used steam consumption, etc. 2. Analyze the proportion of key users in branch lines, main lines, and overall thermal users, and provide scheduling optimization suggestions based on historical data and other factors to assess the impact of key user start stop on corresponding pipeline parameters. 3. Analysis report on peak and valley flow of hot users, statistics on load situation, and analysis to assist in formulating business plans. 4. Comparative analysis of temperature, pressure, and flow curves of thermal users with similar pipelines and diameters to assist in identifying pipeline anomalies.

　　fiveSteam metering management terminalIt has debugging function, and in debugging state, the valve can be opened without recharging. The above functions can be enabled or disabled through the function menu of the controller. The data transmission of the high-level network adopts fiber optic transmission with good compatibility, high reliability, fast data transmission speed, and long transmission distance. Moreover, the long transmission distance can reach 1200 meters, which can reliably meet the needs of low-level data acquisition and transmission. At the same time, it also helps to reduce the distributed capacitance generated between the two 485 communication lines and the surrounding areas of the communication lines

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdSteam metering management terminalEquipped with RS232/RS485 standard communication interface and MODBUS RTU, MODBUS ASC Ⅱ industrial standard communication protocol, it can communicate with intelligent flow meters, read various measurement parameters and working parameters in intelligent flow meters.

　　1. The device has automatic dialing and disconnection redialing functions. When the network condition is unstable, it has the ability to automatically restore communication, ensuring stable system operation without human intervention; When the signal in the area is weak, the module can communicate normally by changing the signal reception and transmission strength of the module.

　　2. Online query function can be achieved through the Internet, and users only need to provide their username and password. The real-time online query function can be completed.

　　3. Equipped with data cable and 12VDC power supply.Steam metering management terminal, heating network energy charging, urban smart heating network applicationData copying function: The main station implements centralized copying of meter readings. Automatically collect data and other information from various meters in the concentrator according to the set reading interval and reading cycle, and have real-time random calling and address selection functions. The remote meter reading system software sends commands to the on-site instruments, so that the data of each instrument is transmitted to the corresponding data acquisition module through the RS-485 interface. The data acquisition module 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. The backup power supply is flexible: using an external battery storage method, different battery capacities can be selected according to actual needs. When the external power supply (ac220v) is interrupted, it can maintain the instruments in the system (flow accumulator, prepaid instrument, etc.) Continuous operation of GPRS or CDMA modules

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdSteam metering management terminal, heating network energy charging, urban smart heating network applicationMeaning: In the context of vigorously 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. existingSmart heating network system for power plantsThere 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.
