Design of Self-Checking Module for Underwater Towed Measuring Platform

In order to achieve the aim of the self-checking of the underwater towed measuring platform. The team designed a multi-parameter acquisition and processing circuits of the cabin environment based on MCU. According to the characteristics of underwater operation, a water immersion detection circuit is designed to monitor whether the cabin is leaking in real time. Digital temperature sensor and humidity sensor are designed to measure the temperature and humidity parameters in the cabin. Multi-channel current and voltage sampling circuits are designed to detect the operating parameters of equipment. The modular design of the system is realized by CAN-bus communication.
