At present, most regions in China adopt the centralized heating model to meet the heating needs of the public. Centralized heating is a process in which heat media, such as steam or high-temperature hot water, obtained from thermal power plants or heating companies, are transmitted through the heat network to heat exchange stations in various residential areas. The heat exchange station is the hub connecting the heat network and heat users. Its function is to regulate, convert, and distribute the heat medium according to the operating conditions of the heat network and user demands, while carrying out centralized metering and parameter detection.

A heat exchange unit usually consists of components such as heat exchangers, circulation pumps, electric control valves, make-up water pumps, water tanks, and control cabinet PLCs. By connecting to a PLC intelligent gateway, data collection and real-time monitoring of various parameters of the heat exchange station can be achieved, abnormal fault trends can be quickly identified and measures taken, ensuring heating safety and energy safety, and helping to build unattended heat exchange stations.

Functional Features

Real-time collection and upload of the operating status and process data of each device in the heating station, facilitating precise regulation of the system, such as supply water temperature, return water temperature, pressure value, heat quantity, flow rate, motor frequency, valve switch status, water tank liquid level, etc.

Collect and count the primary flow and secondary flow data in the heat exchange station, so as to understand the heat exchange situation of the heat exchange station, provide data support for optimizing heat exchange efficiency, and thereby improve energy utilization efficiency.

Support remote upload and download of PLC programs or remote operation and maintenance debugging of equipment, facilitating equipment debugging and parameter adjustment by operation and maintenance personnel, effectively reducing the number and frequency of on-site visits, and improving operation and maintenance work efficiency and management level.

In cases of heavy workload or inconvenient transportation, management personnel can receive automatically sent alarm information, thereby quickly locating, diagnosing, and taking measures, improving response efficiency through remote control means, and avoiding larger accidents.

Realize information-based management of electronic work orders such as inspection, repair, and maintenance, online viewing of the execution progress and operation logs of each work order, and combine resident feedback for review, return, and other operations, realizing the closed loop of operation and maintenance work.
