In winter, the city is faced with rising demand for the quality of heat supply. In an era of energy scarcity, it is urgent to improve heat supply work while saving energy. As the heat supply network is expanding with dispersing worker stations, it has become challenging to monitor the operation data, control and manage the heat network for better economic efficiency, and better utilize heat resources. In light of this, InHand Networks offers a remote networking monitoring solution for heat supply, which can oversee the operation status of the heat supply system, provide accurate and effective data for the heat department, improve the efficiency of heat utilization and ensure secure and stable operation of the devices.

Customer Requirements​

Real-time Monitoring

It is necessary to promptly obtain real-time information on key parameters of the heating station, such as temperature, pressure, flow rate, etc., to ensure the normal operation of the system.

Easy deployment across specific areas

Simple and swift setup in designated zones with user-friendly hardware and easy installation, reducing deployment complexities.

Secure and reliable communications

Robust communication with redundancy mechanisms ensures uninterrupted data transmission to the central monitoring center.

Reliable operation during long periods of time in unattended environments

Design durable hardware resistant to environmental factors, coupled with energy-efficient components, for consistent, long-term operation in unattended or challenging settings.


The on-site IG902 edge computing gateway connects to the heat supply station’s PLC and HMI for data collection, then uploads data from heat exchange stations to the cloud platform via MQTT protocol.

The remote smart heat network platform monitors heat exchange stations, records alarms, performs statistical analysis, manages reports, and handles system administration and BI demonstrations. This B/S architecture platform is accessible from PCs, mobile phones, and tablets.

It effectively manages heat supply station data, including inlet/outlet water temperatures and pressures, compressor status, leakage, temperature thresholds, activation status, and alarms. This solution streamlines traditional manual management challenges, allowing control parameters to be uploaded to the cloud system for real-time fault detection and resolution. This reduces user waiting times and operation costs, enhancing client satisfaction.


High-speed, secure, and reliable network connectivity

The IG902 is available with LTE, Wi-Fi, and wired connections. It incorporates multiple link redundancy technologies to ensure a consistently high-speed and reliable network connection.

Supports major industrial protocols and clouds for easy monitoring
