| Abstract: | The paper devises a control system for ARM9 based sea floor observatory network node circuit to satisfy the real time acquisition requirement of submarine observation data. This system employs the modular design method of an embedded system to construct a circuit system including extended UART communications circuit, analog to digital conversion circuit, ethernet communications circuit, voltage level conversion circuit and USB interface circuit. Simulation and application results prove that this node circuit system has better stability and reliability, and easy to be monitored and maintained by a shore station. |
