Steam IC card prepaid system, general steam metering and charging, intelligent thermal measurement method

Description :

Steam IC card prepaid system, general steam metering and charging, intelligent thermal measurement methodThe mobile data transmission network is a critical part of the system, connecting the past and the future, directly determining the operational effectiveness of the entire system. This part is built and maintained by mobile operators, ensuring reliability and stability, and users do not need to invest any additional funds. The mobile data transmission system for smart heating network metering terminals connects stations and centers through GPRS/LTE communication modules and the Internet (static IP network cables) as a medium. The heating prepayment control system station packages various data and transmits it to the GPRS/LTE communication module through a communication line. The GPRS/LTE communication module encodes and processes the data, converts it into a format for public network data transmission, and sends it to the data network location of the mobile operator. The static IP extracts the data and finally transmits it to the central server.

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdSteam IC card prepaid system, general steam metering and charging, intelligent thermal measurement methodSystem 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. The steam prepayment control device 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 steam IC card prepaid system has the characteristics of fast, real-time, etc., and can complete the entire meter reading task. The RS485 wired data remote meter reading system is generally composed of a system master station and meters. The core of the RS485 wired data remote meter reading system is computer network and communication technology. Currently, the most commonly used communication methods include twisted pair cables, optical fibers, and other communication methods. Moreover, the long-distance 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

Steam IC card prepaid system, general steam metering and charging, intelligent thermal measurement methodA remote meter reading system based on low-power Internet of Things, comprising a terminal meter reading node, a centralized procurement node, a cloud server, a centralized meter reading management platform, and user terminals. The terminal meter reading node of the steam IC card prepayment system collects user meter data, sends the data packet to the centralized acquisition node, the centralized acquisition node and the terminal meter reading node establish a one to many communication mode, and wirelessly transmits the data collected by multiple terminal meter reading nodes to the cloud server. The centralized reading management platform connects the cloud server through the Internet, processes the data collected by the terminal meter reading node, and sends instructions according to the status of the terminal meter reading node. The terminal meter reading node sets a wake-up mechanism to receive instructions and control the response of the data acquisition module and communication module through its main control module. Users can receive payment reminders and view water/electricity/gas/heat information based on the user terminal. System security permission setting function: Permission setting provides comprehensive security authentication, and users cannot enter the system. Legitimate users can perform corresponding operations based on their permissions, such as buying before using, closing valves for overdue payments, and avoiding the traditional "supply first, charge later" energy management model. This is a new trend in modern energy management reform

　　Qingdao Zhiyuan Instrument Prepaid Calculator complies with the JJG1003-2016 standard and meets the trade settlement requirements of the new metering regulations for integrated calculators.

　　A. Instrument model EF-II/TCP, LCD display screen.

　　B. The instrument has an accuracy of ± 0.2% and is capable of outputting 4-20mA analog signal current (output category can be freely defined).

　　C. The function of intelligent accumulation instrument is to measure pressure, temperature, instantaneous flow rate, cumulative flow rate, frequency, differential pressure, steam balance, power outage frequency, power outage and incoming call time, daily cumulative monthly cumulative query, etc. It is programmable and can set parameters according to actual needs;

　　D. Multiple cumulative methods (lower limit flow, over flow), cumulative coefficient (percentage) can be set. It can be set that when the flow rate is less than a certain percentage of the range (such as 10%), the lower limit flow rate will be accumulated according to this fixed value. It can also be set that when the flow rate is greater than a certain percentage of the range (such as 110%), the excess flow rate will be accumulated according to the set multiplier, thus solving the problem of low flow rate in small flow and excess flow measurement and meeting the actual needs of heat network calculation.
