Steam card swiping prepayment system, thermal network metering and charging, wireless data collection principle

Description :

　　As a new generation of energy supply model,Steam card swiping prepayment system, thermal network metering and charging, wireless data collection principleIt 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 network metering and charging can better meet these requirements and achieve multiple functional goals by selecting appropriate technologies, optimizing and integrating the system. According to the actual situation where various meters are relatively concentrated, the low-level network of the system adopts RS485 bus. It has the characteristics of simple structure, low cost, and low wiring requirements. 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

　　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.Steam card prepayment systemData storage backup function: The system database can be stored locally, and its storage time is determined by demand and computer configuration. Curve analysis: It can compare the pressure, temperature, and instantaneous flow values of each instrument in different time periods. Furthermore, obtain their fluctuation situation, clarify the reasons for their fluctuations, in order to formulate corresponding measures. Open database design: support user-defined monitoring station expansion and monitoring sensor expansion. Adapt to the continuous development needs of enterprises

Qingdao Hesheng Zhiyuan Automation System Co., LtdPrepaid intelligent flow display instrument is an intelligent programmable instrument with high measurement accuracy, strong functions, simple operation, and good stability. By using flow meters, pressure and temperature transmitters, or platinum resistors together, a high-precision flow testing system can be formed. Moreover, this instrument provides RS485/232 serial communication interface and USB interface for remote data acquisition and control by computer.Qingdao Zhiyuan Instrument Steam Card Prepaid SystemBased on the on-site conditions of the project, our design adopts a prepaid intelligent flow display instrument to achieve measurement and transmission of prepaid steam flow meters on a flow integrator. The on-site and central display parameters include instantaneous steam flow rate, cumulative steam flow rate, steam temperature, steam pressure, and steam balance.

　　Distributed energy systems, as energy supply centers serving the local area, directly face the needs of local users and are deployed near them. This simplifies the energy transmission process for users, reducing energy losses and transmission costs, and increasing the safety of energy supply for users. Due to its lack of large-scale and long-distance energy output mode, it mainly targets the energy needs of local users,Steam card prepayment systemThe scale will be constrained by user demand, and compared to traditional centralized energy supply systems, it is of medium to small capacity. Data copying function: The main station implements centralized copying of meter readings. Automatically collect meter data and other information from the concentrator according to the set reading interval and reading cycle, and have real-time random calling and address selection functions. System expansion and upgrading function: The system has an open data interface, which facilitates the addition and expansion of monitoring points in the later stage
