Qingdao Hesheng Zhiyuan Automation System Co., LtdIC card prepaid systemThe server is selected as a cloud server, which is convenient for networking and cost-effective. The server system adopts a Windows server 2012 system and SQLserver 2012 database, with a CPU of quad core, 3.1GHz, and 8MB; 8GB memory, 2 * 1TB hard drive,. Install the thermal network metering system software; During network calibration, the measurement data of each user end is collected at a unified time, and the flow meters of each user end are monitored according to the management mode to provide on-site process data for dispatchers; The software used continuously collects various variable information of flow meters from the local metering station system through cloud server network and 4G network, and saves these data in a general database to generate various tables, curves, report information, etc. If there is report information, it is notified to the responsible person through the platform.

　　At present, most heating companies supply steam first and then settle monthly when selling steam, but this may result in some user units defaulting on steam payments, causing inconvenience to heating companies. The steam IC card prepayment control system developed by Qingdao Hesheng Company can effectively eliminate the above-mentioned problems. The steam users of this system must pay in advance and recharge before opening the valve to use steam. They must also renew and recharge before the balance is exhausted. When the balance is insufficient, local and remote notifications will be sent to remind users to pay in a timely manner. If the balance is not renewed in time, the system will automatically close the valve and stop steam when the balance is zero, eliminating the phenomenon of overdue payment by the steam users. combineIC card prepaid systemReal time customer gas usage status, the system control box has unboxing and disconnection reports. Once a customer opens the metering box or system control box without authorization, the data will be immediately transmitted to the control center to remind the staff of the time, and the electric valve will be remotely controlled to close and stop the steam supply, which will have a deterrent effect on malicious behavior by users.

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 IC 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.

Qingdao and Shengzhiyuan IC Card Prepaid SystemPrinciples of Measurement Software Design:

　　The system design follows the basic principles of "mature technology, real-time and fast, safe and reliable, economical and practical, easy to expand, and easy to upgrade".

　　2. The on-site measuring instrument technology meets the standard design, and adopts computer remote mode or assisted management mode.

　　3. Adopting a mature fully open, layered, and fully distributed system structure, the system configuration and equipment selection facilitate the expansion of hardware and functionality, and adapt to the rapid development of computer technology. By fully utilizing the technology in the computer field, the system performance can reach the domestic level, ensuring the safety and reliability of software and hardware, and long-term continuous operation, in order to achieve the goal of "unmanned and few people on duty".

　　4. The main network topology of the system adopts DDN network to enable communication between each station system and the central workstation, realizing data monitoring and functions. Information publishing is achieved through IE browsing through WEB Server, supporting remote access by intelligent terminals.

　　fiveIC card prepaid system, steam metering valve control system, smart heating network standardBased on the GSM network, packet switching transmission method is adopted to overcome the disadvantages of low conversion rate and poor resource utilization of GSM circuits, and to maximize the utilization 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. Communication function: Provides RS485 communication interface, which can be connected through wired, GPRS/CDMA and other methods, using standard Modbus RTU protocol. The inefficient and outdated manual management method of manual meter reading is susceptible to human factors, with poor real-time performance, low reliability, and low efficiency. It cannot detect on-site faults in a timely manner. Due to the inability to collect data from all meters at the same time, it is also difficult to measure and analyze pipe losses, and thus cannot effectively manage the heating network
