Steam meter reading system terminal, steam heating network data collection, intelligent heating network technology maintenance

Description :

　　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.Steam meter reading system terminalThe traditional meter reading method adopts a pure manual reading mode in the process of reading the meter, while in the later stage of measurement, the final cost result is also in manual mode. The automatic fault reporting function: the monitoring point automatically reports the fault information to the monitoring center and prints the report information automatically. The automatic detection of faults includes flow meter communication failure, 220V AC power outage, IC card failure, etc. It can purchase gas, recharge heat, insert cards, and query with IC card technology. With just one insert, it is easy to handle, 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. Communication function: Provides RS485 communication interface, which can be connected through wired, GPRS/CDMA and other methods, using standard Modbus RTU protocol.

　　1. On site operation data 4G real-time upload: 4G wireless communication terminals are responsible for the important task of data transmission, and can upload on-site data to the heating network service center in real time to track and monitor the thermal parameters (pressure, temperature, flow rate, etc.) of the heating network, and grasp the heating status of the entire heating network management line. 2. Flexible networking and rapid deployment: Wireless networking mode has the characteristics of flexible networking, high data transmission rate, wide signal coverage, strong real-time performance, high security, low operating cost, and low maintenance cost; Suitable for situations where equipment is widely distributed and it is inconvenient to install network cables, wireless networking can achieve data transmission without geographical limitations as long as the operator's network coverage is available, shortening the project deployment cycle. 3. Fault diagnosis and analysis, timely fault reminder: on-site collection and measurement instrument failures can also be detected in a short period of time, and the fault time can be recorded and filed to avoid measurement losses and eliminate the idea of users stealing steam. In case of power outages or abnormal collection parameters at the hot user end, information can be timely predicted and personnel can be reminded to handle them through platforms or methods. 4. Remote operation and maintenance management, reducing operation and maintenance costs: Management personnel can see the steam usage of users in various places in the management background, without the need for on-site manual meter reading. Fault report information is convenient for maintenance personnel to check and repair in a timely manner, reducing and saving a lot of manpower and material resources

　　5. The main function of the smart heating network is data storage and backup: the system database can be stored locally, and its storage time is determined by demand and computer configuration. In the late 1980s and early 1990s, pilot work on automated meter reading systems began. Wireless power load control systems have been basically 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. The backup power supply is flexible: it adopts an external battery, and different battery capacities can be selected according to actual needs. When the external power supply (AC220V) is interrupted, it can maintain the continuous operation of instruments (flow integrator, prepaid meter), GPRS or CDMA modules in the system

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdSteam meter reading system terminal, steam heating network data collection, intelligent heating network technology maintenanceSystem 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 and passing the identity verification, the system can enter. The system defines access permissions according to different access users. The intelligent heating network metering system adopts a B/S structure and supports intelligent terminals with internet access functions to access, enabling the operation of the heating network anytime, anywhere and 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 terminal wired data acquisition system of the steam meter reading system is based on the RS485 bus. The RS485 wired data remote meter reading system is a system that uses modern communication and computer network technology to automatically collect remote data. 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. The overdraft function: the "overdraft" function can be selected. For individual special users, they are allowed to have a certain overdraft limit. In the event that the user's balance is used up, they can overdraft a certain amount of steam without closing the valve
