　　Qingdao Hesheng Zhiyuan Automation System Co., LtdHeating enterprise heating network system, power plant prepayment system, intelligent heating network metering functionSystem functions:

　　a. Can query historical data of any hot user, any parameter, and any time period, and support the export and printing functions of statistical reports and analysis curves; Rich report customization printing and archiving functions, which can print hot user daily, monthly, and steam consumption detail reports, parent pipe daily, monthly, and summary reports, and can be archived as EXCEL format files (*. xls). b. Hot user management data system, including flow rate, pressure, temperature, upper and lower limit report settings, current operating parameters of instruments, unit price, special policies, responsible person information, etc., to prevent users from modifying settings; c. Access control function: Operators need to apply for a login name with their personal ID when logging in (non ID cannot be applied for), and achieve real name login; After entering the password, the system can be accessed through identity verification. The system defines access permissions based on different access users. The smart heating construction scheme adopts a B/S structure, supporting intelligent terminals with internet access functions to access the heating network anytime and anywhere, achieving mobile office; e. Geographical distribution map of heating network users and routing map of heating network pipelines, which can be drawn according to the needs of the network and marked with steam flow direction (green line in the figure), locate the coordinate points of heating network users, and display the pipeline distance between heating customers and heat sources;

　　f. The heating network system of heating enterprises should be purchased before use, and valves should be closed for overdue payments to avoid the traditional energy management mode of "supply first, charge later". Modern energy management reform is trendy, and real-time monitoring can achieve real-time data display function for multiple instruments. In order to timely grasp the situation of various department stations, make corresponding adjustments and guidance, the pilot work of automated meter reading system began in the late 1980s and early 1990s. 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

　　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 enterprise heating network system, power plant prepayment system, intelligent heating network metering functionAccording to the actual situation where various meters are relatively concentrated, the low-level network of the system adopts RS485 bus. It has the characteristics of simple structure, low cost, and low wiring requirements. Real time data calling and historical data query can be performed on the backend software. The storage period of historical data is long. In the late 1980s and early 1990s, the pilot work of automated meter reading system began. Wireless power load control systems have been established in various power supply enterprises across the country. Although their main construction purpose is to control loads, they are gradually being used for reading electricity meters for large users. Currently, there are many technologies used for meter reading in China, such as manual meter reading, RS485 bus, infrared and wireless data remote transmission, etc. Among them, GPRS wireless data remote transmission and RS485 bus meter reading technologies are relatively mature and widely adopted. 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

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdHeating Enterprise Heating Network 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. The hot water intelligent heating network system has opened 100 remote metering points, with N metering points used in the first phase. The excess points will be reserved for future expansion preparation;

　　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. Smart heating network video access for gas purchase, heat recharge, card insertion, and inquiry, with IC card technology, can be easily done with just one card, transforming the traditional manual meter reading and pricing into user card based gas and heat purchase. It realizes the automation of gas and heating fee collection and management process, and query statistics: data can be queried and displayed for each instrument at any time during a certain period of time, making it easy to assess and query each shift
