Remote on-line metering system and method of echo sounder

Abstract

The invention discloses a remote on-line metering system of an echo sounder. The system comprises a microprocessor, a remote on-line server module, a carrier wave signal processing module which is connected with the microprocessor and used for capturing and processing carrier wave signals, a signal regeneration transmission module for generating echo signals, a delay control processing module forsequential control, a communication transmission module for data transmission, a data storage module for data storage, a crystal oscillation traceability module for system precision verification and ahuman-computer interaction module for human-computer interaction; the microprocessor is in communication with the remote on-line server module through the communication transmission module; the delaycontrol processing module is also connected with the signal regeneration transmission module, the carrier wave signal processing module and the human-computer interaction module separately. The invention further discloses a remote on-line metering method of the echo sounder by using the system. The remote on-line metering and verification method can achieve remote online verification and calibration of water depth metering parameters of the echo sounder.

Description

technical field [0001] The invention relates to the field of verification and calibration of water depth measurement equipment, in particular to a remote on-line measurement system for an echo sounder and a measurement method thereof. Background technique [0002] The echo sounder is a commonly used measuring instrument in water transportation engineering, which can accurately measure the water depth data during the navigation of the ship, and provides a powerful means of water depth measurement for the majority of marine workers. [0003] At present, the conventional metrological verification method of the echo sounder is: put the echo sounder into the verification water tank, the transducer emits ultrasonic waves vertically downward or horizontally, the echo sounder receives the reflected echo, and the echo sounder shows The value is compared with a known standard value to calculate the measurement error. This method is limited by the size of the verification tank, the me...

AI Technical Summary

Problems solved by technology

This method is limited by the size of the verification tank, the measurement range is limited, the operation is cumbersome, and the verification cost is high

In addition, the user needs to send the instrument to be tested to the verification / calibration unit by express or freight, and the verification / calibration unit will issue the relevant certificate after the verification of the instrument, and then mail the instrument and the certificate to the user. This process causes a lot of labor and time cost
