Problems solved by technology
[0002] At present, there are mainly two sound velocity measurement methods, one is the indirect measurement method, that is, by measuring the temperature, pressure and salinity in water, and then calculating the sound velocity value through empirical formulas, the accuracy of the indirect measurement method depends on the measurement of each parameter The accuracy and the accuracy of the empirical formula are quite complicated to verify; the other is the direct measurement method, the basic principle of which is to calculate the sound velocity by measuring the propagation time of the sound wave within a fixed distance in seawater. The smaller the distance between the ultrasonic transduc

The invention discloses a sound velocity measurement method, circuit and device and a storage medium, and the method comprises the following steps: reading a preset configuration template file in response to a measurement instruction; according to the configuration template file, the clock module is configured, a configuration result is obtained, and configuration is completed; updating the clock frequency of the clock module in real time according to the configuration result; when configuration is completed or clock frequency updating is completed, a driving signal is sent to the ultrasonic receiving and transmitting module to enable the ultrasonic receiving and transmitting module to work, and the sending moment when the ultrasonic receiving and transmitting module sends the transmitted waves and the receiving moment when the ultrasonic receiving and transmitting module receives the reflected waves are recorded; according to the sending time, the receiving time and a preset propagation distance, calculating to obtain a sound velocity value; and according to a preset reading number, a plurality of continuous sound velocity values are read, and an average sound velocity value is calculated according to the plurality of sound velocity values. According to the sound velocity measurement method, circuit and device and the storage medium disclosed by the invention, the sound velocity measurement precision can be improved.
Description
technical field [0001] The invention relates to the technical field of sound velocity measurement, in particular to a sound velocity measurement method, circuit, device and storage medium. Background technique [0002] At present, there are mainly two sound velocity measurement methods, one is the indirect measurement method, that is, by measuring the temperature, pressure and salinity in water, and then calculating the sound velocity value through empirical formulas, the accuracy of the indirect measurement method depends on the measurement of each parameter The accuracy and the accuracy of the empirical formula are quite complicated to verify; the other is the direct measurement method, the basic principle of which is to calculate the sound velocity by measuring the propagation time of the sound wave within a fixed distance in seawater. The smaller the distance between the ultrasonic transducer and the reflector, the higher the requirement for the accuracy of time measurem...
