Embodiment 1: as shown in Figure 1, discharge of river real-time online measuring device, including programmable controller 1, transmitting mould
Block 3 and receiving module 4, transmitting module 3, receiving module 4 are connect with 3 signal of transmitting module, the radar wave that transmitting module 3 issues
Scanning angle it is adjustable.
Programmable controller 1 connects transmitter 2, flow measurement module 7, signal output module 8 and display module 9, can
Program sequence controller 1 receive the concatenated signal of network server 6, programmable controller 1 by control instruction be transmitted to transmitter 2,
Flow measurement module 7, signal output module 8 and display module 9.
Transmitter 2 emits (a pair or one group) ping to water body by transmitting module 3, these pings encounter water
Back wave is generated after particles suspend in body and with water sports, and records the frequency shift between transmitted wave and back wave,
This frequency shift claims Doppler frequency shift, can calculate speed of the water flow relative to transmitter 2 accordingly.
The scanning angle for the radar wave that transmitting module 3 is issued is adjustable, so that the measurement range of separate unit flow measurement device
It is significantly increased, in this way, need to only use small number of flow measurement device, the flow in whole river can be monitored, can substantially be dropped
The monitoring cost of low river discharge.
Transmitting module 3 includes several antenna elements, and each antenna element is connect with 2 signal of transmitter.
Receiving module 4 receives radar wave after the refraction that transmitting module 3 is issued, and radar wave after refraction is become to transmit information

Sequence controller 1 sends information to flow measurement module 7.
Flow measurement module 7 can (the river channel including being placed in be several according to the information of the sectional view for measuring riverbed
What size, river slope coefficient, river channel precision, river waterpower ramp, river flow vertical plane correction factor), measurement
Water level out and water flow is calculated, water flow section product, flow rate of water flow, water flow section product * water flow are calculated according to sectional view and water level
The flow velocity * time=flow, obtain flow results；River discharge refers to the volume for passing through river cross section in the unit time, calculates
Method be by the average speed of the cross section with river water multiplied by area of section, river discharge river length is unrelated, only and river
The flowing water speed of stream is related with area of section.
