摘　　要：为实现深海海底观测网络的长期连续观测,设计一套基于水下接驳技术的接驳盒原型系统.通过分析接驳盒体系结构,采用多个耐压密封腔体作为水下接驳盒的机电集成封装结构,完成耐压腔体机械结构和散热结构设计.在实验的基础上,利用MOSFET器件以输入串联和输出并联相结合的方式,把2kV高压直流电转换为400V中压直流电,实现深海远距离高压直流电能传输.针对深海观测仪器设备通信的实时性要求,采用基于TCP/IP的光以太网技术和应用层自定义协议技术来实现通信控制.实验验证了在40MPa下,水下接驳盒原型系统能够正常工作.该水下接驳盒原型系统合理且实用,为实现深海海底观测网络的长期连续观测提供了技术支撑.A suit of junction box prototype system which is based on underwater junction technology was designed to implement long-term continuous observation for deep seafloor observatory network.Based on analysis of the junction box framework,a waterproof pressure-resistant multi-housing was chosen as mechanical and electronic integration encapsulation structure of the underwater junction box,and the mechanical and thermal structures were designed for the pressure-resistant housings.On the basis of experiments,a new method by arraying MOSFET parts in series on the input side and in parallel on the output side was proposed to transform 2 kV high-voltage DC to 400 V middle-voltage DC,consequently the deep-sea long-distance high-voltage DC power transmission was implemented successfully.Considering the real-time request of the deep-sea observation equipments,the optic Ethernet technology based on TCP/IP and the application layer user-defined protocol technology were chosen to implement communication control.The results of pressure experiments showed that the junction box prototype system can work normally at 40 MPa.As results,the junction box prototype system is proved to be reasonable and practical,which is expected to be used for the implementation of long-term continuous observation for deep seafloor observatory network.
