The above-mentioned components are all prior art, and their specific structures and working principles will not be described in detail here.
[0023] The power board 3 realizes external input power boost and step-down conversion, and provides stable voltage power supply for devices including the Jetson host 2, the interface board 4, the switch 6 and the image box 8;
[0024] The Jetson host 2 serves as a control and processing core unit of the image collector, and is assisted by the interface board 4 to realize interactive communication between the image collector and the on-board computer, encoding processing of the original image of the image sensing unit connected to the switch 6 and related device monitoring functions;
[0025] The switch 6 realizes mutual communication between various network devices in the local area network, and supplies power for network devices supporting POE. The 8-port POE switch inside the device is connected to the Jetson host 2 and the image box 8 through network cables, and external devices can be connected to zoom lens industrial cameras, fixed focus lens industrial cameras and other image sensing units, and broadband satellite communication network data links and the like;

The power supply is 28V (or 12V).
[0027] The interface board 4 is an auxiliary interface expansion board of the Jetson host 2, mainly realizing serial port expansion and conversion function of the Jetson host 2, and being connected with the Jetson host 2 through a 40-pin. The 4-way UART serial port is expanded through the SPI interface of the Jetson host 2, and the serial port expansion including 2-way RS422, 1-way RS485 and 1-way RS232 is realized through the corresponding interface conversion chip. The 1-way RS422 interface and 1-way RS485 interface conversion are realized through the 2-way UART serial port of the Jetson host 2, which is used for external computer communication and zoom lens control box control. The on-board temperature and related power voltage acquisition function is realized through the I2C interface of the Jetson host 2. The on-off control including switch power supply, image box 8, power board 3 and heating film power supply is realized through the IO port of the Jetson host 2.
