Background technology
The built Simple rain gauges overwhelming majority adopts tipping-bucket rain-gauge as sensor to mountain flood prevention at this stage, this
, due to measuring key element using tipping bucket rotatable parts as core, in the case of heavy rain, precision is relatively low for class sensor.In addition information is sent out
Cloth is limited in scope, and locally can only report to the police.
In addition, applying most for tipping-bucket rain-gauge and siphon rainfall recorder in prior art, tipping-bucket rain-gauge sets
Two tipping buckets are equipped with, the precipitation in rain container is injected in two tipping buckets in turn, and a tipping bucket is overturn after being filled with, and is turned over therewith
Permanent magnet on bucket drives dry bourdon tube adhesive once, sends an electric impulse signal, and then another tipping bucket is turned over after being filled with
Turn, export an electric impulse signal again therewith, and so on overturn, the time statistics precipitation occurred with record electric impulse signal
And precipitation intensity.Due to tipping bucket capacity very little, therefore it is not suitable for measuring heavy showers process, its maximum rainfall intensity of permission is
4mm/min, furthermore, the current of heavy showers are easy to overturn tipping bucket so as to overturn when water is not filled in advance, cause larger
Measure error.Siphon rainfall recorder carries a float chamber, and the precipitation in rain container is injected into float chamber, the float in float chamber
A recording pen is driven to move up and down so as to record the drop of the period in a recording sheet for being driven and rotated by recording clock
, when water column rises to siphon point in float chamber, there is siphonic effect in water curve, and after siphon, float chamber water column declines, and float is with
Move, restart next section of dropdown curve record, the precipitation of siphon discharge and so on, is recorded and counted by the human metering water yield
Measure rainfall intensity and the rainfall of whole period.Because of the restriction of structure, the udometric capacity of its float-type cannot do the rainfall gauge
Greatly, if for measuring heavy showers process, siphonic effect can be frequently occurred, it is interrupted record excessive, causes larger metering to miss
Difference, therefore, is not suitable for measuring heavy showers process.And above two rainfall gauge because electronization and digitized degree relatively low,
Accuracy of measurement and resolving power be not high, accuracy of measurement only ± 4%, is extremely difficult to the accurate measurement to rainfall.
