Prepaid management for industrial parks, smart heating network management, and fee management software for the heating industry

Description :

Prepaid management for industrial parks, smart heating network management, and fee management software for the heating industryA remote meter reading system based on low-power Internet of Things, comprising a terminal meter reading node, a centralized procurement node, a cloud server, a centralized meter reading management platform, and user terminals. The meter reading node of the prepaid management terminal in the industrial park collects user meter data, sends the data packet to the centralized acquisition node, the centralized acquisition node and the terminal meter reading node establish a one to many communication mode, and wirelessly transmits the data collected by multiple terminal meter reading nodes to the cloud server. The centralized reading management platform connects the cloud server through the Internet, processes the data collected by the terminal meter reading node, and sends instructions according to the status of the terminal meter reading node. The terminal meter reading node sets a wake-up mechanism to receive instructions and control the data acquisition module and communication module response through its main control module. Users can receive payment reminders and view water/electricity/gas/heat information based on the user terminal. 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 intelligent meter reading system is developed using modern scientific technology, and can directly rely on system calculations in both the reading and cost measurement stages. Therefore, the automation level of the intelligent meter reading system is much higher than that of traditional meter reading

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdPrepaid management for industrial parks, smart heating network management, and fee management software for the heating industryDesign 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 implementation details of smart heating are highly reliable and will not affect the normal operation of on-site metering 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, which is easy to develop and maintain with strong flexibility, allowing end users to truly open up without the need to write statement instruction programs.

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 a flow meter, pressure, temperature transmitter, or platinum resistor together, a flow testing system can be formed, and this instrument provides RS485/232 serial communication interface and USB interface for remote data acquisition and control by computer.Prepaid Management of Qingdao Zhiyuan Instrument Industrial ParkBased 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.
