ABSTRACT
There is an urgent need for marine ecological environment monitoring in China at present, but the traditional manual periodic sampling and testing has such disadvantages as low monitoring frequency and limited station coverage, which could not meet the requirements of large-scale real-time continuous data for current marine ecological early-warning monitoring. Therefore, constructing the multi-level, multi-system, and multi-space marine ecological environment online monitoring system could effectively develop marine ecological environment early-warning monitoring capacity. In this paper, the concept of "System of Systems" was introduced into the construction of marine ecological environment online monitoring equipment system, and the architecture of "System of Systems" of the monitoring equipment was constructed from two layers, structure layer and function layer. The composition of the two layers, and the difficulties in construction of the two layers were emphatically discussed. The paper also analyzed the methods of developing "System of Systems" of marine ecological environment online monitoring system.
