The main functions of the smart heating network include steam metering, card swiping, and recharging, as well as GPRS wireless meter reading software

Description :

becauseMain functions of smart heating networkThere is a significant time delay in heat transfer during operation. By predicting the load of the heat production unit, appropriate adjustments can be made to the heat production plan based on the specific heat needs of the network, thereby improving the thermal efficiency of the entire heating network system. IC card prepaid management is a new heating network composed of a heating physical equipment network (a network composed of heat sources, heating pipe networks, user systems, local display instruments, and control and regulation devices), a heating information Internet of Things (a network composed of sensors, data collection devices, data transmission devices, etc.), and an intelligent decision-making system based on an intelligent heating platform, referred to as the intelligent heating network. Intelligent heating is based on the heating physical equipment network and supported by the heating information Internet of Things. Through an intelligent decision-making system, it provides auxiliary decision-making support for operation and management personnel, forming a heating system form that reduces operating energy consumption while ensuring indoor comfort.

The main functions of the smart heating network include steam metering, card swiping, and recharging, as well as GPRS wireless meter reading softwareIt can also provide the user unit with greater regulation, control, and guarantee capabilities, ensuring that various secondary energy sources of the user unit can be fully supplied. It is very suitable for providing electricity, heating, and cooling to developing areas, commercial and residential areas, rural areas, pastoral areas, and mountainous areas, greatly reducing environmental pressure. In short, distributed energy systems can meet the needs of special occasions, provide possibilities for the comprehensive cascade utilization of energy, open up new directions for the utilization of renewable energy, and make outstanding contributions to improving energy utilization efficiency, enhancing safety, and addressing environmental pollution. This is also a very important advantage. The main function of the smart heat supply network is to automatically generate various production reports and statistical reports of users' steam consumption, so that the supervisor can timely grasp the thermal production situation, timely solve various problems encountered in production, calmly realize the centralized dispatching management of colleges and universities, change the passive management mode to the active management mode, and replace it with a new computer information management. The system integrates the functions of automatic collection, automatic settlement, remote prepayment and intelligent charging of water, steam, heat and other energy data to develop an intelligent remote prepayment system. The IC card prepayment system consists of a prepayment control box; Explosion proof (explosion-proof) electric control valve; Card reader/writer (including recharge software); Items 1, 2, and 3 are installed at the on-site measurement point, while item 3 is installed on the office computer of the management personnel.

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdThe main functions of the smart heating network include steam metering, card swiping, and recharging, as well as GPRS wireless meter reading softwareSystem 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 identity verification, the system can enter. The system defines access permissions according to different access users. d. Steam prepayment anti-theft management adopts a B/S structure, supporting 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 main function of the smart heating network is to upload data such as valve position and flow rate, 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 as needed (address range: 1-128, baud rates: 2400, 4800, 9600), and the prepaid box will prompt on the upper computer after opening the door. After the interruption of the mains power (ac220v), the upper computer will prompt the automatic fault reporting function: the monitoring point will automatically report the fault information to the monitoring center and print the report information automatically. The faults detected automatically include: communication failure of flow meter, 220V AC power outage, IC card failure, etc

Main functions of Qingdao and Shengzhiyuan Smart Heating NetworkPrinciples 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.

　　fiveThe main functions of the smart heating network include steam metering, card swiping, and recharging, as well as GPRS wireless meter reading softwareFlexible backup power supply: using an external battery, 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 the system's instruments (flow integrator, prepaid meter), GPRS or CDMA modules. System expansion and upgrading function: The system has an open data interface, which facilitates the addition and expansion of monitoring points in the later stage
