Then require system that can also automatically adjust transmission power while automatically adjusting gain of received signal so as to receive signal
Voltage is maintained at a stable range, this is most important for the precision of systematic survey.
Currently, multibeam echosounder is in different depth of water depth, different water body environments and different underwater geological conditions environment
Under the conditions of, it needs to adjust transmission power manually according to return signal intensity.Such mode working efficiency is low, is not easy to measure work
Efficient progress；Additionally, there are more manual interventions, can not ensure the accuracy of measurement result, cannot be satisfied modern surveying
The requirement of technology.
Invention content
It is received by reception energy converter after the acoustic signals reverberation water body of multibeam echosounder transmitting, since the depth of water differs, water
The influence for the complex situations such as body environment is changeable, the acoustic signals of return have different degrees of decaying, cause accurately to receive
Echo-signal.In this case with regard to needing the echo-signal to reception to carry out gain-adjusted, transmission power is even adjusted, makes to connect
Collection of letters stability maintenance is in the stable region of setting, and then multibeam sounding system could use received signal, accurately carry out water
Deep value measures.
The present invention provides a kind of adjusting methods of the adaptive dynamic adjusting system of multibeam echosounder, realize and receive signal
Gain and transmission power adaptation dynamic regulation, therebetween mutually coordinated realization recycle dynamic regulation so that receive signal electricity
Pressure is maintained at stable region, ensure that the measurement accuracy of multibeam sounding system.
The present invention is achieved through the following technical solutions above-mentioned purpose：
A kind of adjusting method of the adaptive dynamic adjusting system of multibeam echosounder, includes the following steps：
A, Sonar Signal is emitted by display and control software control transmitting transducer, by reception energy converter after Sonar Signal reverberation water body
It is received and converted to weak electric signal, which sends AD sampling modules to through gain control unit；
B, the AD sampled values that AD sampling modules extract are judged by processor, if AD sampled values are preset
In stable region, then it need not adjust and receive signal gain, system executes subsequent operation；If AD sampled values are not being preset
Stable region in, then by processor control gain control unit increase or reduce gain of received signal, keep reception signal adaptive
It should be in stable region；
C, gain of received signal changes preprocessor and judges again AD sampled values, if AD sampled values are set in advance
In fixed stable region, then it need not adjust and receive signal gain, system executes subsequent operation；If AD sampled values do not exist still
In stable region, then display and control software is controlled according to AD sampled values by processor and increase or decrease transmission power；
D, above-mentioned a, b, step c are executed successively again after transmission power change, forms cycle and adjusts, until making reception signal certainly
Until adapting in stable region.
Further, the stable region is between the 30%--70% of AD reference values.
While the present invention realizes automatic adjustment gain of received signal, transmission power can be also automatically adjusted, and pass through association
Gain of received signal is adjusted to realize cycle dynamic regulation with transmission power so that reception voltage signal is maintained at stable region, ensures
Operation efficiently carries out, and solves and uses manual adjustment gain of received signal and transmission power in the prior art, efficiency is low, nothing
Method ensures the technical issues of multibeam sounding system measurement accuracy；Meet the development trend of modern measure technology.
