The underwater multi-node is a device that can sample and process underwater acousto-magnetic signals. Due to the nodes contain digital, analog, and digital-analog hybrid interfaces, and different types of functional modules are mixed together, the test of the node circuit is not easy to achieve. In this article, I designed a set of test software for underwater multi-node circuits. It can automatically monitor the power supply of the node circuit and the status information of the interface, and can also quickly judge whether the function of the circuit and the interface are wrong.
