These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0028] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0029] like Figures 1 to 5 As shown, the utility model provides an embodiment of a cross-network screen one-way secret transmission device. In this embodiment, the cross-network screen one-way secret transmission device is used in conjunction with two cabinets, namely, an encryption display cabinet 100 and a collection and decryption cabinet 200.

[0030] In this embodiment, a 21.5-inch LCD screen 101 is installed on the front of the encryption display cabinet 100 for management personnel to operate the device. A face recognition camera 103 is installed in the middle position above the screen for management personnel to identify their identities in order to obtain operating permissions. The camera 103 has a lens angle that supports fine-tuning of ±15° up and down, and is connected to the computer host through a USB interface inside the cabinet. An operation tray 104 for placing a keyboard and a mouse is designed in the middle of the front of the encryption display cabinet 100, that is, below the screen. The inclination slope of the operation tray 104 conforms to ergonomic design. The cabinet adopts a double-door design at the bottom, is equipped with a height-adjustable shelf, and is installed with a computer host (not shown). The graphics card inserted in the computer host supports dual HDMI interface output, which is respectively connected to the 21.5-inch LCD screen 101 on the front and the 43-inch LCD screen 102 on the back. Fish scale heat dissipation holes are designed on both sides of the cabinet to achieve internal and external circulation ventilation. The back is equipped with an embedded 43-inch LCD screen 102. The LCD screen 102 is set in a vertical screen. The image encryption technology is used to encrypt the screen to be transmitted to the business system and then display it in real time. A three-core power socket, an RJ45 network cable socket 105 (for access to the external network) and a USB interface are set below the LCD screen 102 to facilitate line connection. A supporting device 106 is also installed under the cabinet, such as casters with locking devices and height adjustment legs, which can facilitate the movement of the device and appropriately adjust the verticality of the cabinet according to the use environment.

[0031] In this embodiment, the external dimensions of the encrypted display cabinet are: 650mm (width)*1700mm (height)*300mm / 530mm (depth).

[0032] A 21.5-inch LCD screen 201 is installed on the front of the data collection and decryption cabinet 200 for management personnel to operate the device, and a face recognition camera 203 is installed in the middle position above the screen for management personnel to identify their identities in order to obtain operating permissions. The camera 203 has a lens angle that supports fine-tuning of ±15° up and down, and is connected to a computer host (not shown) via a USB interface inside the cabinet. An operation tray 204 for placing a keyboard and mouse is designed below the screen, and the inclination slope of the operation tray 204 conforms to ergonomic design. The bottom of the cabinet adopts a double-door design, is equipped with a height-adjustable shelf, and is equipped with a computer host. The graphics card inserted in the computer host is connected to the 21.5-inch LCD screen 201 on the front via an HDMI interface. Fish-scale heat dissipation holes are designed on both sides of the cabinet to achieve internal and external circulation ventilation. A USB3.0, high frame rate, 8-megapixel industrial HD camera 202 is installed on the back of the cabinet. It supports auto focus, and the lens angle supports manual adjustment of ±45° up and down and ±15° left and right. The installation height is the same as the center area of ​​the 43-inch screen on the back of the encryption display cabinet. The encryption display cabinet 100 and the acquisition and decryption cabinet 200 are placed back to back, about 1.5-2 meters apart. The computer host on the acquisition and decryption cabinet 200 decodes the picture through image decryption technology and displays it in the business system and on the LCD screen 201. Unauthorized personnel cannot view the content of the picture, realizing one-way encrypted transmission of the screen picture across the network (from the external network to the internal network). A three-core power socket, RJ45 network cable socket 205 (access to the internal network) and USB interface are set below the screen to facilitate line connection. A support device 206 is also installed below the cabinet. If casters with locking devices and height adjustment legs are used, the movement of the device can be facilitated and the verticality of the cabinet can be appropriately adjusted according to the use environment.
