[Abstract]:With the rapid development of science and technology in China, more and more exploitation and utilization of the ocean are used. As a favorable tool for marine development, sonar is becoming more and more important. The performance of a sonar is directly related to the performance of the underwater acoustic transducer, so the measurement of the transducer parameters is especially important.
The automatic measuring device for transducer parameters is a set of devices that can automatically measure the parameters of the transducer. The design goal is to make the measuring device easy to operate, work stable and reliable, the measurement precision and the level of automation are high, and can automatically measure the transmission voltage response of the transducer.
The whole automatic measuring device is composed of two parts of hardware and software. The hardware platform is based on the floating point DSP TMS320F28335. It has the capability of frequency sweep signal transmitting, A/D collection and communication with the computer through serial port. The software part includes: (1) the display and control software that is developed by Visual C++ and running on the computer, Its function includes measurement parameter setting, measurement device running state display and control, measurement result data display, auto save, print and so on; (2) DSP software program developed in CCS environment, its function includes control of DDS, A/D and processing of collected data. Measurement device can automatically measure parameters according to the display control software The measuring results are returned to the upper computer. The automatic measurement items that can be realized by the measuring device include the transducer transmission voltage response, the spatial directivity and the acoustic environment signal to noise ratio. In addition, the display control also includes automatic screen screenshot, Word report generation, print control and error prompting. The process can be carried out automatically. Under the premise of accurate measurement, the workload of the operator is reduced and the work efficiency is improved.
After a long time laboratory test and several tank tests, it is proved that the operation of the automatic measuring device is stable and reliable, the result of the measurement is accurate, and all the technical indexes have reached the design requirements.
