Abstract:

In order to improve the performance of underwater acoustic detection, its electronic devices continue to be modified and upgraded, the traditional use of various types of standard instruments for its detection, in terms of cost, detection cycle, operational complexity and other aspects have significantly increased, in view of the above problems, the design of a automated detection system. The design principle of the detection system, the hardware design method and the method of testing software set up by the underwater acoustic detection device are expounded. In the design of detection software, a database Edior mechanism is proposed for the development of CAN communication software module, which simplifies the process of CAN session handle creation and uses stream mode to realize CAN communication, which improves the efficiency of CAN frame data reception. For the short modulation pulse signal test, the accurate test is realized by using the multi-threaded method of channel trigger.Using the detection system to test the underwater acoustic detection device, the effect shows that the operation is convenient and fast, the detection cycle is significantly shortened, and the desired effect is fully achieved.
