Qingdao Hesheng Zhiyuan Automation System Co., Ltd. IC Card Prepaid ManagementMeasurement software follows standards:

　　Specification for Computer Software Quality Assurance Plan GB/T12505

　　General Technical Specifications for Microcontrollers GB/T9813-2000

　　GB 4728.1-85 "Symbols for Electrical Diagrams"

　　Standard for Intelligent Flow Display Instrument JJG1003-2016

　　Vortex Flow Meter JB/T9249-2015

　　Verification Regulations for Vortex Flowmeters JJG1029-2007

　　Verification Regulations for Differential Pressure Flowmeters JJG640-2016

　　Differential Pressure Flow Meter GB/T2624-2006

　　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.

　　Application of Qingdao STR/WEB/V2.0 Qingdao Zhiyuan Instrument Intelligent Heating System: IC card prepayment managementThe main application is to achieve intelligence and ensure thermal balance of heat source output. Install temperature, pressure, flow and other sensors at each heat source unit and pipeline outlet to calculate the energy consumption of each link, display information on inlet and outlet temperature, pressure, flow and other aspects. The sensors will send the collected information to the heating dispatch center to achieve real-time monitoring of various parameter information.IC card prepaid management, steam energy charging system, intelligent heating network management functionIn the application of heat source, it is also necessary to monitor load and weather changes, combine specific weather and load conditions, adhere to the principle of economic operation, compare the required heat with the heating amount, draw the trend curve of changes, and judge whether to start or stop the furnace. This will meet the heat needs of users without energy waste and save heating costs.

Qingdao and Shengzhiyuan IC Card Prepaid ManagementPrinciples 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.

　　fiveIC card prepaid management, steam energy charging system, intelligent heating network management functionThe main functions are to collect user data, store data, regularly upload data through GPRS network, and receive instructions from the central server. The main function of the central server is data storage, analysis, and timely statistics of data uploaded by various measuring devices through statistical analysis. At the same time, it can also detect problems early and provide query and analysis functions to management personnel through various means. Real time release of scheduling information: using computer information and communication technology, monitoring information and business information of scheduling functional departments are timely released to the enterprise network or the Internet, realizing the sharing of public information resources. The composition of the IC card gas sales management system: the main hardware includes IP network cables, servers, IC card readers and writers, etc. The main software includes operating system software, database software, heat network data IC card management system software, firewall software
