The Remote Monitoring System of the Heat Exchange Station

In recent years, the scale of urban central heating has continued to expand. Central heating is an energy-saving and environmental protection measure worthy of vigorous promotion. The heat exchange station is an extremely important link connecting the heating station and the user. Its working safety and reliability directly affect the safety and heating quality of the boiler. At present, manual monitoring is used in many areas of the heat exchange station, which wastes manpower on the one hand; on the other hand, it is difficult for operators to find hidden dangers of accidents, which may easily cause equipment accidents. At the same time, each heat exchange station operates independently, especially for central heating equipment, which has a large dispersion range and high real-time requirements, and must also avoid interference. To achieve real-time and continuous monitoring of the surrounding environment of the heat exchange station, the traditional method in the past is difficult to meet the requirements.

The remote monitoring system of the heat exchange station of the 4G industrial router consists of four parts: a monitoring center, a wireless transmission terminal, on-site monitoring equipment, on-site measuring instruments, and measurement and control equipment.

The system structure and main functions are composed of four parts: monitoring center, wireless transmission terminal, on-site monitoring equipment, on-site measuring instruments and measurement and control equipment. 1. Monitoring center: that is, the central server, upper computer monitoring software, etc. 2. Wireless transmission terminal: industrial 3g 4g sim router, based on wireless communication network. 3. On-site monitoring equipment: monitoring terminal 4. On-site measuring instruments and control equipment: heat meters (or flow meters, pressure sensors, temperature sensors, etc.), valves (or pump starter cabinets), etc.

Among them, the wireless transmission terminal can adopt E-Lins industrial router. E-Lins now has 5G industrial routers H685f and H900f for selection. The E-Lins industrial-grade wireless router can provide stable and uninterrupted network access for heat exchange stations with high temperature and scattered locations. On-site data can be safely transmitted to the data center through the VPN function of the router. The monitoring software and group of the data center of the heating company Statistical software for statistics and analysis of data.

E-Lins industrial routers have a variety of interfaces, including wired network port RJ45, two serial ports RS232 or RS485, Digital I/O, etc. There are a variety of functions to choose from, such as GPS, WiFi, 5-60V wide voltage, etc. E-Lins industrial-grade routers have been widely used in M2M industries in the IoT industry chain, such as smart grids, smart transportation, smart homes, financial IoT wireless communication routers, mobile POS terminals, supply chain automation, industrial automation, smart buildings, Fire protection, public safety, environmental protection, meteorology, digital medical care, remote sensing survey, agriculture, forestry, water affairs, coal mining, petrochemical and other fields.

Realization of the system: the system will simultaneously transmit information such as equipment operation and maintenance status to the monitoring center and various production management departments in real time, providing accurate information for production command and dispatch, reducing the required on-site duties and maintenance personnel, and ensuring maximum replacement The hot station production is running normally.
