GPRS meter reading and metering terminal, wireless remote meter reading system, customized steam intelligent heating network

Description :

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 GPRS Meter Reading and Measurement TerminalBased 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.

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdGPRS meter reading and metering terminal, wireless remote meter reading system, customized steam intelligent heating networkDesign principle:

　　1. The operator workstation in the center adopts a B/S structure, supporting remote access to intelligent and other intelligent terminals (with internet access). Using the above technologies, modular and structured application software suitable for the actual needs of this project is developed, making the system more adaptable to the increase in functionality and scale expansion; The software adopts a mature standardized Chinese system, with a user-friendly interface and easy operation. The displayed images and printed files are clear and eye-catching.

　　2. The system has high reliability, strong resistance, high availability, and good maintainability.

　　3. The steam intelligent charging system is highly reliable and will not affect the normal operation of on-site measuring equipment due to local faults.

　　4. The measurement system software includes four major parts: computer operating system software, database software, tool software, and application software. The application software is based on the JA framework and adopts a modular (functional module) structure, with high development efficiency, easy maintenance, and strong flexibility, allowing end users to truly open up without writing statement instruction programs.

　　Application of Qingdao STR/WEB/V2.0 Qingdao Zhiyuan Instrument Intelligent Heating System: GPRS meter reading and metering terminalThe main application is to achieve intelligence and ensure thermal balance of heat source output. Install temperature, pressure, flow and other sensors at each heat source unit and pipeline outlet to calculate the energy consumption of each link, display information on inlet and outlet temperature, pressure, flow and other aspects. The sensors will send the collected information to the heating dispatch center to achieve real-time monitoring of various parameter information.GPRS meter reading and metering terminal, wireless remote meter reading system, customized steam intelligent heating networkIn the application of heat source, it is also necessary to monitor load and weather changes, combine specific weather and load conditions, adhere to the principle of economic operation, compare the required heat with the heating amount, draw the trend curve of changes, and judge whether to start or stop the furnace. This will meet the heat needs of users without energy waste and save heating costs.

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdGPRS meter reading and metering terminal, wireless remote meter reading system, customized steam intelligent heating networkTechnical specifications for measuring instrument stations: The measuring station is installed in the factory of the steam unit, with one set per unit, including intelligent flow integrator, 4G module, antenna, data cable, unboxing equipment, DC backup power supply (UPS), wall mounted instrument box, and power distribution system. 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. Adopt 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.
