Prepaid system for external steam supply, GPRS data collection, principle of superheated steam terminal

Description :

Prepaid system for external steam supply, GPRS data collection, principle of superheated steam terminalTechnical parameters such as metering stations and flow meters: The metering stations are installed one by one in the steam unit's factory, including intelligent flow display instruments, IC card controllers, GPRS modules, antennas, data cables, unboxing equipment, DC backup power supply (UPS), wall mounted instrument boxes, and power distribution systems. All devices should have replaceability and universality. The above devices need to be integrated into one chassis, and the connections between devices have been integrated and debugged as a whole before leaving the factory; Protection level IP65.Steam prepayment control deviceAdopt protective measures such as pressure-sensitive and TVS to deal with and solve potential accidents such as voltage fluctuations, vibrations, electromagnetics, and lightning strikes in the power grid. At present, the main operating parameters and equipment operations in the factory production process can be collected and managed through a distributed system

　　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.Prepaid system for external steam supply, GPRS data collection, principle of superheated steam terminalWith the continuous development of urban construction and the expansion of supply areas such as hot water, steam, tap water, and gas, the traditional manual meter reading method can no longer meet the requirements of enterprises for cost recovery, instrument operation status, and the construction of digital management technology platforms. In the management room, the network browsing function can provide a clear view of the entire system, enabling 24-hour operation of the heating network. All physical quantity data in the system is displayed on the screen, informing users of steam parameters and pipeline operation parameters. In the event of a fault, it can reach * *. Based on the GSM network, a packet switching transmission method is adopted to overcome the disadvantages of low conversion rate and poor resource utilization of the GSM circuit, and to maximize the use of existing GSM network resources. It has a high transmission rate, short access time, and users are online in real time and charged based on traffic, quickly reducing service costs. It is particularly suitable for sudden small traffic data transmission. The IC card gas sales management system consists of the following hardware: IP network cable, server, IC card reader/writer, etc. The main software includes operating system software, database software, heat network data IC card management system software, firewall software. Curve analysis: It can compare the pressure, temperature, and instantaneous flow values of each instrument at different time periods. Furthermore, obtain their fluctuation situation, clarify the reasons for their fluctuations, in order to formulate corresponding measures

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdPrepaid system for external steam supplyEquipped 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. In case of unstable network conditions, it has the ability to automatically restore communication, and the system works stably 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.Prepaid system for external steam supply, GPRS data collection, principle of superheated steam terminalThe 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 data management function is: data browsing: historical data can be browsed separately, and these data can be deleted, queried, and printed. For example, information stored in the database can be browsed, such as meter readings, statistical data, curve data, event data, etc., and these data can be exported to generate corresponding reports for printing. The fault automatic reporting function: monitoring points automatically report fault information to the monitoring center and print report information. The faults detected automatically include: communication failure of flow meter, 220V AC power outage, IC card failure, etc

　　becausePrepaid system for external steam supplyThere is a significant time delay in heat transfer during operation. By predicting the load of the heat production unit, appropriate adjustments can be made to the heat production plan based on the specific heat needs of the network, thereby improving the thermal efficiency of the entire heating network system. The GPRS remote meter reading software is a new heating network composed of a heating physical equipment network (a network composed of heat sources, heating networks, user systems, local display instruments, and control and regulation devices), a heating information Internet of Things (a network composed of sensors, data collection devices, data transmission devices, etc.), and an intelligent decision-making system based on an intelligent heating platform, referred to as the intelligent heating network. Intelligent heating is based on the heating physical equipment network and supported by the heating information Internet of Things. Through an intelligent decision-making system, it provides auxiliary decision-making support for operation and management personnel, forming a heating system form that reduces operating energy consumption under the premise of indoor comfort.
