Smart heating should be a case study, energy management of heating companies, and standardization of steam pre charging systems

Description :

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 should be a case studyAfter opening the prepaid box, a prompt will appear on the upper computer. After the interruption of the mains power (ac220v), the upper computer prompts that the GPRS remote meter reading system has functions such as system maintenance, real-time monitoring, query and statistics, curve analysis, etc

　　Qingdao Zhiyuan InstrumentSmart heating should be a case studyFunction 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 steam valve control system can directly add heating customers through the front-end webpage, with convenient and fast operation, sorted by number, and the order of customer arrangement can be freely adjusted; 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 steam prepaid flow meters are set and controlled by administrators to prevent unauthorized operations by personnel at different levels;

　　As a new generation of energy supply model,Smart heating should be a case study, energy management of heating companies, and standardization of steam pre charging systemsIt is a powerful supplement to centralized energy supply systems. With the development of economy and technology, especially the active application of renewable energy, users' energy demands have begun to diversify; With the development and maturity of different energy technologies, there are increasingly more technologies to choose from. Distributed energy systems, as an open energy system, are showing a trend towards multifunctionality, including multiple energy inputs and meeting multiple energy needs of users simultaneously. People's concepts are constantly changing, and new requirements are constantly being put forward for the energy system (reliability, economy, environmental protection, sustainable development, etc.). The new Qingdao Zhiyuan Instrument Thermal Power Company's energy management can better meet these requirements and achieve multiple functional goals by selecting appropriate technologies, optimizing and integrating the system. Real time monitoring: It can achieve real-time data display function for multiple instruments. Easy to timely grasp the situation of various department sites, make corresponding adjustments and guidance, flexible backup power supply: using an external battery, different battery capacities can be selected according to actual needs. When the external power supply (ac220v) is interrupted, it can maintain the continuous operation of the system's instruments (flow integrator, prepaid instrument), GPRS or CDMA modules. The GPRS remote meter reading system has functions such as system maintenance, real-time monitoring, query and statistics, curve analysis, etc

　　1. On site operation data 4G real-time upload: 4G wireless communication terminals are responsible for the important task of data transmission, and can upload on-site data to the heating network service center in real time to track and monitor the thermal parameters (pressure, temperature, flow rate, etc.) of the heating network, and grasp the heating status of the entire heating network management line. 2. Flexible networking and rapid deployment: Wireless networking mode has the characteristics of flexible networking, high data transmission rate, wide signal coverage, strong real-time performance, high security, low operating cost, and low maintenance cost; Suitable for situations where equipment is widely distributed and it is inconvenient to install network cables, wireless networking can achieve data transmission without geographical limitations as long as the operator's network coverage is available, shortening the project deployment cycle. 3. Fault diagnosis and analysis, timely fault reminder: on-site collection and measurement instrument failures can also be detected in a short period of time, and the fault time can be recorded and filed to avoid measurement losses and eliminate the idea of users stealing steam. In case of power outages or abnormal collection parameters at the hot user end, information can be timely predicted and personnel can be reminded to handle them through platforms or methods. 4. Remote operation and maintenance management, reducing operation and maintenance costs: Management personnel can see the steam usage of users in various places in the management background, without the need for on-site manual meter reading. Fault report information is convenient for maintenance personnel to check and repair in a timely manner, reducing and saving a lot of manpower and material resources

　　5. Curve analysis of steam heating network platform: It 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. The permissions of the sub centers are limited to data monitoring and are not allowed to operate downwards, ensuring the security of the system. The data of each sub center in the main center is fully synchronized and displayed in real time. The system security permission setting function: permission settings provide complete security authentication, and users cannot enter the system. Legitimate users can perform corresponding operations according to their permissions, buy first and use later, close valves in arrears, and avoid the traditional "supply first, charge later" energy management mode. This is a new trend in modern energy management reform
