Disclosed is an operation and maintenance method and system for automatically and uniformly managing nodes of bastion host. No matter distribution of user permission, daily deployment of machine monitoring and network monitoring or batch management of daily operation and maintenance, the operation and maintenance method and system can be abstracted as follows: master control dispatches a Master of a certain area node to issue and execute a certain task, and unified management is naturally achieved; the design concept can be continued subsequently. A Master host in the node serves as a master controller of the node, and related contents including a tool script library, a crontab task and a configuration file are preset in a Redis of the node in advance; when a new machine is accessed to a certain node, the new machine is configured to perform Salt-Master access management of the node where the new machine is located, and the corresponding machine is controlled to complete the corresponding task through a takeover program; therefore, unified and automatic management is realized.

The present disclosure discloses a dual-wavelength high-spectral resolution lidar system based on a dual-stage virtual image phased array. The system includes a dual-wavelength vertically polarized light emission system, first to sixth beam splitting systems, a first photodetector, a telescope, a first band-pass filter, a second band-pass filter, a second photodetector, a first dual-stage virtual image phased array system, a third photodetector, a first ICCD acquisition system, a fourth photodetector, a second dual-stage virtual image phased array system, a fifth photodetector, a second ICCD acquisition system, and a timing controller. The system has abilities of real-time detection of subsurface information in an ocean, phytoplankton vertical layered structure, vertical profile distribution of temperature and salinity of sea water, and spatiotemporal variabilities of the mixed layer depth, thereby effectively solving existing problems and shortcomings in a current ocean exploration technology, to provide a system solution for further realization of a transparent ocean.
