Design and Implementation of Interface Modularization for Special Testing Equipment of Torpedo

To improve the efficiency of interface design for special testing equipment of torpedo(STET), a method of interface design based on modularization is proposed. According to the function, the hardware of the interface is divided into three of standard modules, i.e. the signal attenuating module, the analog signal isolating module, and the digital/switch signal isolating module. Signals can be conditioned by combining these modules. Simulation and measurement show that these modules can achieve the function of signal condition well and realize modularization and standardization of the interface for STET.
