Qingdao Zhiyuan InstrumentSmart heating energy-saving systemService commitment:

　　From the date of delivery of the heating network system, it enters the after-sales service period. The after-sales service period includes a free warranty period and a quality maintenance period.

　　Free warranty period: Within 12 months from the date of normal use of the product or system, it is a free warranty period. During the free warranty period, any quality issues within the warranty scope will be repaired and replaced by Party B free of charge.

　　Quality maintenance period: After the quality assurance period, we will continue to provide lifetime preferential services. The maintenance services carried out during the quality maintenance period will be charged material and labor costs based on the spare parts product price (not higher than the contract price) and maintenance situation set by the company.

　　The specific service items during the after-sales service period are as follows: receiving letters from users, providing responses or handling suggestions within 24 hours, and ensuring user satisfaction. And store the corresponding information in the user maintenance record sheet.

Design of intelligent heating energy-saving system, thermal network meter reading system, and thermal network pre charging systemReport function: Automatically generate * * *, monthly reports, annual reports, and can also perform statistical reports and printing at any time. Automatic printing function can be set up, and the GPRS meter reading system communicates with the main station computer through the GPRS network connected to the Internet network. The user's data is processed and protocol encapsulated by the GPRS module before being sent out. It is then received by the GPRS receiving module and transmitted to the main station via the Internet network, achieving real-time online connection between the user's energy consumption data and the main station

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 Intelligent Heating Energy saving 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.

　　With the trend of informationization and intelligence development in the heating network, the existing heating network collection system is no longer suitable for new intelligent management requirements. It is necessary to upgrade and add functions to the existing hardware and software systems to build a smart heating network management system.Smart heating energy-saving systemValve adjustment function 1: In manual mode, after inserting the device card, the valve opening can be adjusted through the keyboard. In automatic mode, after recharging, the valve will slowly open automatically. Equipped with remote control mode, the valve opening can be adjusted through the upper computer. Real time monitoring: It can achieve real-time data display function for multiple instruments. The IC card gas sales management system is composed of hardware such as IP network cables, servers, and IC card readers/writers. The main software includes operating system software, database software, heat network data IC card management system software, and firewall software. The remote meter reading system software sends commands to the on-site instruments to transmit the data of each instrument to the corresponding data acquisition module through RS-485 interface. The data acquisition module automatically reads various data information from each meter according to the meter reading task issued by the management center, such as pressure, temperature, flow rate, power outage information, hour, day, month data, etc. After the prepaid box is opened, it prompts on the upper computer. After the interruption of the mains power (ac220v), the upper computer prompts

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdDesign of intelligent heating energy-saving system, thermal network meter reading system, and thermal network pre charging systemDesign 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 management of steam metering prepayment is highly reliable and will not affect the normal operation of on-site metering equipment due to local failures.

　　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.
