Winter heating is an important life support for northern residents, and heating equipment needs to operate stably around the clock. In this paper, through the industrial IOT heating monitoring system, Delta PLC is used as the control system, and industrial configuration and site monitoring are carried out through HMI touch screen to realize Ethernet connection communication between heating site and monitoring center to monitor the heating conditions in real time and adjust the site parameters in time according to the site conditions to improve the automation management of heat exchange stations, reduce operation cost and enhance reliability.
The monitoring objects of this IOT heating monitoring system are mainly PLCs and sensors, instruments and other devices. By connecting such lower devices through industrial IOT gateways and upper platforms such as HMI touch screens, data such as temperature, pressure, heat, flow, liquid level, pump and valve start/stop status are collected and controlled so that managers can observe the site situation at any time and take timely measures.
(1) Remote monitoring
Real-time collection of operating data of equipment such as water outlet temperature, water return temperature, indoor temperature and electricity for heating, support 5G/4G/WIFI/Ethernet for data communication, through the remote operation and maintenance center can view the information of each site, timely regulation of water supply temperature, and effectively avoid the phenomenon of uneven heating and cooling.
(2) Cloud configuration screen
Free to set up industrial configuration, by dragging and dropping controls and binding good data to achieve the display of equipment process flow diagram, you can intuitively see the real-time operation status of equipment, remote control of equipment, to achieve visual management of on-site equipment. It can be viewed on PC, APP and on-site touch screen, which is convenient to understand the operation status of equipment anytime, anywhere, intuitively and visually in real time.
(3) Remote intelligent alarm
The data of the heating system can be monitored 24 hours a day. When the system detects a failure or abnormal situation of the heating equipment, the gateway will inform the person in charge in a timely manner by various means (telephone voice, SMS, message push, webpage voice, etc.) at the first time. So that the management personnel can grasp the relevant situation and dynamics in time to make corresponding adjustments.
(4) Remote maintenance
With the help of equipment maintenance express, engineers can remotely connect to the site PLC, download the program, programming and debugging operations, saving time and effort, with high efficiency, and complete maintenance work without leaving home.
