Introduction To Industry Scenarios
The core of water conservancy engineering is flood control, water supply, irrigation, ecological water replenishment, and water resource scheduling. It is characterized by outdoor activities, large temperature differences (-30 ℃~60 ℃), thunderstorms/exposure/freezing, long distances, large water bodies, high sediment content, and unmanned operation.
Typical measuring points:
Reservoir/dam: reservoir water level, water level in front of/behind the dam, leakage water level, spillway water level, water level before and after the gate
River/embankment: river water level, mudflat water level, gate station water level, flood season water level warning
Irrigation area/pump station: water level of main channel/branch channel, water level of pump station front pool/outlet pool, pump group pressure, irrigation pipe network pressure
Storage tank/sponge city: storage water level, rainwater well liquid level, pipeline pressure, flood prevention warning
Hydroelectric power station: tailwater level, collection well level, pressure pipeline pressure

Addressing Industry Issues
Outdoor environment is harsh, instruments are prone to damage
Exposure to sunlight/freezing/thunderstorms/mud, ordinary instrument lifespan is 3-6 months, poor lightning protection, winter frost cracking, and difficult maintenance.
Inaccurate water level, lagging scheduling, high flood control risks
Slow manual water level measurement, lagging data, poor accuracy, untimely flood season warning, scheduling errors, risk of dam overflow and collapse, and huge losses.
Long distance signal instability and susceptibility to lightning strikes
Long field wiring, frequent thunderstorms, signal packet loss/interruption, lightning strikes burning instruments, no data in dispatch centers, and command paralysis.
High cost and low efficiency of manual duty
There are many sites, wide distribution, remote areas, low efficiency of manual inspection/recording, high security risks, and untimely data.
Water resource waste, uneven irrigation
Unstable water levels in channels, manual water distribution, overflow waste, water shortage at the end, low irrigation efficiency, and significant agricultural losses.
