Video telemetry terminal enables on-site data acquisition and remote transmission for water conservancy and hydrology applications

Video telemetry terminal is a microprocessor-controlled industrial intelligent gateway designed for hydrological, meteorological, and geological monitoring scenarios. It facilitates data acquisition and storage, multi-protocol communication, and remote control. Its low-power design supports solar power supply, while its wide operating temperature range and rugged protection make it suitable for unmanned field monitoring stations.

As a microprocessor-controlled industrial electronic device serving as the core unit at the field end of SCADA systems, Video telemetry terminal handles data acquisition, local storage, network transmission, and remote control tasks. It is widely deployed in meteorological, hydrological, and geological monitoring projects. The device is categorized by application scenario—including hydrology/water resources, groundwater, weather stations, and geological monitoring stations—and can integrate modules for monitoring water levels, rainfall, meteorological elements, pest conditions, and soil moisture. It is well-suited for unmanned sites such as flash flood warning systems and reservoir safety monitoring stations.

The device utilizes a low-power hardware architecture that supports solar power, making it ideal for field monitoring locations lacking mains power. Communication interfaces include RS232, RS485, Bluetooth, 4G, and BeiDou. It is compatible with IPv4 and IPv6 network protocols, supports domain name access, and can report monitoring data to multiple IP addresses simultaneously, enabling a "one-station-to-multiple-destinations" reporting mode. The hardware integrates 4-20mA analog signal inputs, digital input modules, and relay output interfaces, allowing for the connection of multiple sensors and the remote start/stop control of field equipment.

The unit features an industrial-grade protective design with an operating temperature range of -40°C to +85°C, enabling it to withstand harsh field environments characterized by extreme temperatures and high humidity. An integrated, independent temperature and humidity module monitors internal conditions in real-time, allowing for the tracking of environmental changes within the enclosure. The circuit board incorporates multiple protection circuits to minimize short-circuit risks caused by electrical anomalies and to enhance stability during long-term field operation.

Video telemetry terminal integrates data acquisition, edge computing, and multi-protocol communication capabilities, specifically designed for monitoring scenarios in the water conservancy industry. Raw data—such as water levels, rainfall, and soil moisture—collected by the device undergoes basic local preprocessing before being uploaded to a central monitoring station via wireless networks. Control commands issued by the monitoring center can be relayed via the terminal to field execution equipment—such as valves and pumps—to enable remote regulation. In projects involving water resource dispatching, flood warning systems, and long-term groundwater monitoring, the terminal provides a continuous, stable stream of data to operational platforms, serving as a reliable source of field information; this reduces the frequency of manual on-site inspections and lowers the O&M costs of field monitoring projects.
