Abstract: In view of the singleness and specificity of the traditional circuit board test system, in order to meet the automatic test requirements of different circuit boards in a certain type of UUV electronic system, a general automatic test system of circuit board based on virtual instrument is designed. This paper systematically introduces the hardware design and software design, focuses on the key technologies such as universal detection interface design, equipment self diagnosis design, state monitoring module design and signal processing algorithm design, and compares the test efficiency of traditional manual test mode and automatic test mode. The test results show that the circuit board automatic test system can realize the automatic test of different types of circuit boards of a certain type of UUV. On the premise of ensuring the accuracy of the test results, the test accuracy and efficiency of the circuit board are improved.
