【Domestic NI Alternative】Application of Data Acquisition Cards in Landslide Disaster Monitoring and Early Warning
Recently, a severe landslide disaster occurred unexpectedly due to continuous rainfall and complex geological conditions. Such sudden events not only severely threaten the lives of local residents but also cause immense damage to infrastructure. In this context, the role of data acquisition cards becomes crucial. By integrating data acquisition cards with various sensors (such as rain gauges and draw-wire displacement sensors), we can perform real-time monitoring of critical areas like rainfall and geological conditions, accurately collecting key information such as displacement, flow, and rainfall. This data helps us better understand environmental change trends and promptly identify potential landslide hazards.

Monitoring Role of Rain Gauges
Rain gauges play a particularly important role in landslide monitoring, as rainfall is one of the primary factors triggering landslide disasters. By accurately measuring rainfall in specific areas, rain gauges can provide timely precipitation data to help predict the likelihood of landslide occurrence.

Role of Draw-Wire Displacement Sensors
The function of draw-wire displacement sensors is to precisely measure minute displacements on the mountain surface or foundation and monitor the stability of the mountain in real time. When displacement occurs, the sensors capture the changes and transmit the data to the monitoring system. This displacement data can reflect the deformation trend of the mountain, thereby providing early warning of landslide risks.

Solution
To ensure the accuracy and real-time nature of data acquisition, it is recommended to use high-precision voltage acquisition cards paired with voltage output type sensors. Its working principle diagram is as follows:
Q
Gigabit Ethernet Communication: Provides high-bandwidth, low-latency data transmission, ensuring reliable data transfer.
16-Channel Synchronous Acquisition: Multiple acquisition channels, allowing simultaneous acquisition of multiple data points.
1MHz High Sampling Rate: A high sampling rate enables real-time monitoring and feedback of rainfall and mountain displacement changes.
Solution Advantages and Value
The core role of data acquisition cards is not only reflected in real-time data collection but also in acting as a crucial link between sensors and the monitoring system.
By combining historical data with real-time monitoring changes, the early warning system can generate landslide risk prediction maps, identifying potential landslides or floods in advance and providing a time window for disaster occurrence, thereby effectively protecting people's lives and property.
