Description :

Smart heating information management, smart heating network for heating enterprises, metering management system for thermal power plantsPartial Function Introduction:

　　The data analysis function includes steam analysis of the sum of total table and settlement flow, steam analysis of settlement flow of each sub table and branch line, represented in the form of curves and reports, and can automatically generate pipe losses for each pipeline;

　　The system software adopts a networked design, supporting multiple network interfaces and remote browsing. After running the program on the server side, the screen will be published, and various data can be shared by other departments of the thermal power plant through the IE browser. The system has communication function with the power plant MIS system and can transmit the heat network signal to the upper information management system;

　　The centralized gas supply management system supports large screen projection function, which can send geographic graphics, data, curves, pipeline diagrams, etc. displayed on the computer to the large screen, making the system have good visibility;

　　The design of system software and hardware can facilitate future expansion, upgrading, and transformation; The hardware adopts modular design, which is convenient for transformation and upgrading.

　　Equipped with operation logs, it can query the operation process and modify parameters of each customer, achieve traceable and orderly supervision, and avoid operational errors that cannot be traced

Smart heating information managementAbnormal situation report or upload: The system prompts and reports the following four situations. According to user settings, when the balance of the gas bill is less than the set reporting value (on-site sound and light), the remote data demonstration function can be used. In addition to the main dispatch center, the system can establish a sub center at any place where it wants to be built. It can be connected to the main center through GPRS network, which greatly facilitates user management and use

　　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.Smart heating information managementThe system integrates the functions of automatic collection, automatic settlement, remote prepayment, and intelligent charging of energy data such as water, steam, and heat, and develops an intelligent remote prepayment system. 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, etc. Curve analysis can achieve numerical comparison of pressure, temperature, and instantaneous flow of each instrument in different time periods. Furthermore, their fluctuation situation can be obtained, and the reasons for their fluctuations can be clarified in order to formulate corresponding measures for real-time monitoring. Real time data display function for multiple instruments can be achieved. It is convenient to timely grasp the situation of various department sites, make corresponding adjustments and guidance, and have remote data demonstration functions. In addition to the main dispatch center, the system can establish sub centers at any place where it wants to build sub centers. It is connected to the main center through GPRS network, which greatly facilitates user management and use

　　Distributed energy management system is relative to traditional centralized energy supply systems. Traditional centralized energy supply systems use large capacity equipment, centralized production, and then transmit various types of energy to numerous users over a large area through door transmission facilities (such as large power grids, large heat grids, etc.); Distributed energy systems, on the other hand, are small and medium-sized energy conversion and utilization systems that directly face users, produce and supply energy on-site according to their needs, have multiple functions, and can meet multiple objectives.Smart heating information managementGPRS wireless network provides a simple means of communication and transmission for heating systems. The GPRS system can provide wide area wireless IP connectivity. The wireless data transmission of on-site instrument data has the advantages of fully utilizing existing networks, shortening construction periods, and reducing construction costs. In addition, the equipment is easy to install and maintain, and the IC card prepaid system consists of a prepaid 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 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 accumulation methods (lower limit flow, over flow), and the accumulation coefficient (number) can be set. It can be set that when the flow rate is less than a certain number 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 number 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.
