Pre paid flowmeter for heating network, vortex flowmeter data collection, and steam meter reading system functions

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.Prepaid flowmeter for heating networkValve closing function: After the purchased steam is used up, the valve will automatically close. The valve closing action can be set according to the actual situation, such as closing 50%, 40%, or 30%, and the specific value is set by the user themselves. Power outage protection function: Raw data can be saved for ten years during a power outage, and the development of technology has led to the increasing application of automation in work. With the continuous development of enterprises and the increasing number of various meters, traditional manual meter reading can no longer meet the requirements of modern enterprises, and is gradually being replaced by RS485 wired data remote meter reading systems. IC card prepaid flow meters also have RS485 communication, realizing data remote transmission and valve adjustment functions. The main functions are to collect user data, store data, regularly upload data through GPRS network, receive central server instructions, etc. The main functions of the central server are data storage, data 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

Qingdao Hesheng Zhiyuan Automation System Co., Ltd. Prepaid flowmeter for heating networkMeasurement 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.

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdPrepaid flowmeter for heating networkEquipped with RS232/RS485 standard communication interface and MODBUS RTU, MODBUS ASC Ⅱ industrial standard communication protocol, it can communicate with intelligent flow meters, read various measurement parameters and working parameters in intelligent flow meters.

　　1. The device has automatic dialing and disconnection redialing functions. When the network condition is unstable, it has the ability to automatically restore communication, ensuring stable system operation without human intervention; When the signal in the area is weak, the module can communicate normally by changing the signal reception and transmission strength of the module.

　　2. Online query function can be achieved through the Internet, and users only need to provide their username and password. The real-time online query function can be completed.

　　3. Equipped with data cable and 12VDC power supply.Pre paid flowmeter for heating network, vortex flowmeter data collection, and steam meter reading system functionsThe wireless remote intelligent meter reading system is built on the network of the GPRS data management center established within the enterprise. Through the mobile GPRS network, all incoming traffic data is transmitted to the data center. 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 collection module through the RS-485 interface. The data collection 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. Query and statistics: It can query and display the data of each instrument at any time period of a certain period, which is convenient for assessing and querying each shift
