The industrial gateway is the “throat” of the Industrial IoT, deployed at the edge close to the data source. Its core function is to achieve deep integration of IT (Information Technology) and OT (Operational Technology).
Main Functions:
- Data Acquisition and Protocol Conversion: Connects downwards to various sensors, meters, PLCs, and other OT devices, converting their respective private protocols or standard industrial protocols (like Modbus) into common protocols recognizable by IT systems (like MQTT, HTTP).
- Edge Computing and Processing: Locally filters, deduplicates, and calculates (e.g., averaging, finding extremes) massive high-frequency raw data, reducing the upload of invalid data.
- Local Linkage and Control: When abnormal data is detected, the gateway can directly trigger alarms or control commands locally (e.g., closing a valve), achieving millisecond-level rapid response without waiting for cloud commands.
- Secure Isolation and Transmission: As the boundary between internal and external networks, it provides security mechanisms like firewalls and VPN encryption to protect the underlying industrial network from external attacks.
Features and Common Application Scenarios of Tespro Industrial Gateways:
- Smart Water Pump Station Monitoring: In unattended remote pump stations, the Tespro gateway collects data on pump current, voltage, vibration, as well as pipe pressure and flow. Its edge computing function can determine in real-time whether the pump is idling or overloaded, directly stop the machine locally for protection, and simultaneously upload alarm information encrypted via the 4G network to the water management platform.
- CNC Machine Networking: In machining workshops, the Tespro gateway collects in-depth data such as spindle speed, feed rate, and alarm codes of machine tools through specific CNC protocols (like Fanuc, Siemens). Combined with ISTAR software, it helps enterprises achieve tool life prediction and production efficiency analysis.
- Smart Building Energy Consumption Management: The Tespro gateway docks with various smart electricity meters, water meters, and heat/cold meters in the building. With its rich protocol library, it easily accommodates meters from different manufacturers, uniformly aggregating energy consumption data to the cloud to provide data support for energy saving and emission reduction.
