Smart heating network operation and management, intelligent charging for water supply enterprises, smart heating management and maintenance

Description :

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdSmart heating network operation and managementEquipped 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. When the network condition is unstable, it has the ability to automatically restore communication, ensuring stable system operation 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.Smart heating network operation and management, intelligent charging for water supply enterprises, smart heating management and maintenanceAt present, most gas companies sell natural gas and coal gas first, and then settle the gas payment every month. However, there may be some user units who find various reasons to delay the gas payment, which increases the difficulties for gas supply enterprises. Based on the relatively concentrated situation of various meters, the low-level network of the system adopts RS485 bus. It has the characteristics of simple structure, low cost, and low wiring requirements. The IC card prepaid system consists of a prepaid control box; Explosion proof (explosion-proof) electric control valve; Card reader/writer (including recharge software); Items 1, 2, and 3 are installed at the on-site measurement point, while item 3 is installed on the office computer of the management personnel.

Smart heating network operation and managementOn site instrument installation:

Smart heating network operation and management, intelligent charging for water supply enterprises, smart heating management and maintenanceInstalling a protective box on the primary measuring equipment of the pipeline can provide shelter from wind and rain, protect the equipment, and extend its service life; 2、 It can prevent unauthorized operation of measuring equipment. Any type of flow meter is not suitable for the operation and management of smart heating networks. Choosing a flow meter that is suitable for the working conditions of heat users is the rigorous method. For steam metering schemes, the mainstream schemes are divided into two types: vortex street type and differential pressure type. In the actual heating process, we will cooperate with your side to conduct on-site inspections to determine which flow meter is more suitable for use.

Qingdao and Shengzhiyuan Smart Heating Network Operation and ManagementPrinciples 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.

Automatic fault reporting function: Monitoring points automatically report fault information to the monitoring center and print the report information automatically. The faults detected automatically include: communication failure of flow meter, 220V AC power outage, IC card failure, etc

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdSmart heating network operation and managementThe 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.
