Step 7: remote online server module adds up the pendulous frequency that i-th section is examined and determine distance to add 1, judges i-th section
Whether the pendulous frequency of calibrating distance is less than M, if being less than M, return step two；
Step 8: then change calibrating distance segment serial number i repeats step 2 to step 7, until completing to all calibrating distances
The calibrating of number of segment measures；
Step 9: the simulated determination depth value of remote online server module, M measurement for examining and determine distance to i-th section is averaging
ValueAnd it willWith the standard test depth value of settingIt compares, judges whether to meet measurement verification standard；If meeting metering
Standard verification then generates electronics calibration certificate；If not meeting measurement verification standard, rejection notice of verification is provided.
8. echo depth sounder remote online metering method according to claim 7, which is characterized in that in step 4, i-th section
Examine and determine the analogue transmission time t of distancei, it is calculated by formula 1:
In formula 1:
For i-th section of standard test depth value；
F is the frequency of effective carrier signal；
ti, for the analogue transmission time of i-th section of calibrating distance.
9. echo depth sounder remote online metering method according to claim 7, which is characterized in that in step 5, signal
It regenerates sending module and the adjusting of multichannel amplitude voltage, pulse width control and filtering processing is carried out to the analog echo signal of generation.
10. echo depth sounder remote online metering method according to claim 7, which is characterized in that in step 1, every section
Examine and determine pendulous frequency M >=5 of distance.
