Design and sea trial of the ocean sensors integrated interface platform

According to the comprehensive test requirements of commercial and self-developed marine sensors carried on the Smart Float, an ocean sensor integrated interface platform is developed, which is composed of underwater connection unit and shore-based control center. The underwater connection unit contains the main controller, serial port server, Ethernet switch, and remote transmission equipment, etc. and it communicates with the shore-based control center through a twisted-pair or armored cable. The underwater connection unit is designed to implement the functions of power management, sensor electric current monitoring, environment temperature monitoring, and data self-storage, while the shore-based control center is designed for remote control, curve drawing, and data storage. The offshore test results indicate that our design provides an efficient and stable platform to simulate the Smart Float, ROV and HOV interfaces, and carry out the integrated connection test for the marine sensors. It demonstrates the outstanding ability for the comparison of self-developed sensors and commercial sensors, as well as the scientific application of carbon storage and oxygen capacity.
