Intelligent heating network management, GPRS valve control system, steam IC card prepaid application

Description :

　　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.

　　Overall, a distributed energy system with renewable energy as the mainstay and flexible diversification is a vigorously developing energy optimization supply model in this century. Various new distributed energy systems are constantly being introduced, and with the advancement of science and technology and the development of high-performance new materials, distributed energy will occupy an increasingly large proportion in the social energy structure, which will have a crucial impact on social development. The economy has entered a period of rapid development, with increasing energy demand and supply bottlenecks becoming a long-term problem. Cities must learn to manage their own energy, as this is a key link in ensuring urban development and a basic requirement for the quality of urban managers.Intelligent heating network management, GPRS valve control system, steam IC card prepaid applicationQuery and statistics: Each instrument can be queried and displayed for data at any time during a certain period of time, making it easy to assess and query each shift. After the prepaid box is opened, it will prompt on the upper computer. After the interruption of the mains power (AC220V), a prompt will be displayed on the upper computer to provide necessary means for scientific scheduling and management of enterprises such as water supply, steam supply, heating, tap water, and gas; And the application of this meter reading system will reduce the difficulty of meter reading work, improve work efficiency, and continuously reduce the cost of meter reading and charging. The wired data acquisition system based on RS485 bus and RS485 wired data remote meter reading system is a system that uses modern communication and computer network technology to automatically read remote data

　　Qingdao Zhiyuan InstrumentIntelligent heating network managementFunction Introduction:

　　1. Dynamic display of valve status, unboxing status, instantaneous flow rate, pressure, temperature, cumulative flow rate, etc. for each hot user, with different colors used to represent different statuses; When each user point is in normal state, it is displayed in blue. When the parameters exceed the limit, it is reported, or there is a fault, it is displayed in red and flashes, and information is synchronously sent to notify personnel; 2. Real time historical data and curves of flow rate, pressure, temperature, density, differential pressure, and frequency are displayed in the same coordinate system, and can be freely compared. The mouse follows and displays the current data, which is intuitive and easy to analyze; 3. The prepaid calculator for the heating network can directly add heating customers through the front-end webpage, with convenient and fast operation. It sorts by number and can freely adjust the order of customer arrangement; Provide detailed information on thermal units, establish maintenance information for measuring equipment, and facilitate management personnel to query the history and current status of instruments; 4. Automatically generate daily, monthly, annual, and report forms, and be able to print reports in real time. Reports can be made according to the requirements of the thermal company. 5. Thermal user management data system, including flow rate, pressure, temperature, upper and lower limit report settings, instrument current operating parameters, unit price, special policies, responsible person information, etc., to prevent users from modifying settings; 6. Multi level operation permissions for wireless meter reading system are set and controlled by administrators to prevent unauthorized operations by personnel at different levels;

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdIntelligent heating network managementThe server is selected as a cloud server, which is convenient for networking and cost-effective. The server system adopts a Windows server 2012 system and SQLserver 2012 database, with a CPU of quad core, 3.1GHz, and 8MB; 8GB memory, 2 * 1TB hard drive,. Install the thermal network metering system software; During network calibration, the measurement data of each user end is collected at a unified time, and the flow meters of each user end are monitored according to the management mode to provide on-site process data for dispatchers; The software used continuously collects various variable information of flow meters from the local metering station system through cloud server network and 4G network, and saves these data in a general database to generate various tables, curves, report information, etc. If there is report information, it is notified to the responsible person through the platform.
