[0032] Reference Figures 1 to 5 In one embodiment of the present invention, a visual isolation data acquisition terminal includes:

[0033] The box body 100 forms a closed cavity;

[0034] A first industrial computer 200 is provided in the housing 100 and receives and processes image information via a wired manner;

[0035] A display screen 300 is provided in the housing 100 and is electrically connected to the first industrial computer 200 , and the display screen 300 displays image information sent by the first industrial computer 200;

[0036] A mounting bracket 400 is installed and fixed in the box 100. The mounting bracket 400 includes a horizontal bracket 410 and a vertical bracket 420 connected to the horizontal bracket 410. The horizontal bracket 410 is slidably connected in the width direction of the box 100.

[0037] The camera 500 is mounted on the mounting bracket 400 and is arranged corresponding to the display screen 300. The vertical bracket 420 is extended and retracted in the height direction of the box to drive the camera 500. The camera 500 captures and collects information displayed on the display screen 300.

[0038] The second industrial computer 600 is disposed in the box 100 and is electrically connected to the camera 500 to receive image information sent by the camera 500.

[0039] In the existing technology, the communication hardware of the network-gateway isolated collection type equipment is on the same circuit board, which poses certain security risks. In general, it is necessary to use network equipment such as firewalls to strengthen security protection, resulting in relatively high enterprise collection costs.

[0040] In the present invention, the box body 100 forms a closed cavity, providing a storage space for subsequent components.

[0041] The first industrial computer 200 is housed within the housing 100 and receives and processes image information via a wired connection. The first industrial computer 200 receives relevant image information (information presented as images) transmitted from the field. A digital imaging system may be installed within the first industrial computer 200, which encodes and encrypts the data into a graph, which is then displayed on the display screen 300. During this process, the first industrial computer 200 removes sensitive information through intelligent filtering. The digital imaging system can set a time interval for generating the graph, adjusting it based on user needs. The digital imaging system can monitor the connectivity status of the link with field equipment and the data reading status, and output prompts to the display screen 300 to help the user troubleshoot the problem.

[0042] The display screen 300 is provided in the housing 100 and is electrically connected to the first industrial computer 200. The display screen 300 displays image information sent by the first industrial computer 200. The display screen 300 does not contain sensitive information. The display screen 300 is a conventional LCD or LED display screen.

[0043] The mounting bracket 400 is fixedly installed in the box 100 and is used to mount the camera 500 so that the camera 500 can obtain a better collection effect.

[0044] The camera 500 is installed on the mounting bracket 400 and is set corresponding to the display screen 300. The camera 500 collects the information displayed on the display screen 300. At this time, there is no sensitive information in the collected information. The type and model of the camera 500 are selected according to actual needs and are not the focus here. The structure of the mounting bracket 400 is set so that the degree of freedom of the mounting bracket 400 is improved. The installation adjustment between the horizontal bracket 410 and the vertical bracket 420 can adjust the position of the camera 500. Then, the specific position of the display screen 300 collected by the camera 500 is changed. The horizontal bracket 410 is slidably set on the box body 100. For example, a mounting hole is set at a corresponding position on the box body 100, and the horizontal bracket 410 is passed through the mounting hole so that the horizontal bracket 410 can slide therein. At this time, the position of the camera 500 in the width direction of the box body 100 is also adjusted. The vertical bracket 420 can be a telescopic drive structure such as an electric push rod. When the horizontal bracket 410 slides, the vertical bracket 420 drives the camera 500 to move horizontally, while the vertical bracket 420 drives the camera 500 to move vertically. The camera 500 can achieve position shifting within a vertical two-dimensional plane to meet the image acquisition requirements at different positions of the display screen 300.

[0045] The second industrial computer 600 is electrically connected to the camera 500 and receives information sent by the camera 500. The second industrial computer 600 can only store relevant information; or the second industrial computer 600 can also forward the received information to an external server. In this case, the second industrial computer 600 needs to be connected to the external server, and the communication method between the second industrial computer 600 and the server can be wired or wireless. Both the first industrial computer 200 and the second industrial computer 600 can be set to automatically start when powered on to avoid manual startup operations. The second industrial computer 600 can automatically adjust the focal length of the camera 500 according to the clarity of the received information. The first industrial computer 200 receives information in a wired manner, reducing the risk of relevant information being intercepted.

[0046] In summary, the first industrial computer 200 is connected to the on-site equipment via a wired connection, lacking a signal transmitter and posing no risk of intrusion. The second industrial computer 600, through the camera 500, achieves contactless data transmission with the first industrial computer 200. The second industrial computer 600, through the camera 500, non-contactly identifies the data graph displayed on the display screen 300, obtains the on-site data after parsing it through the graphic transmission system, and finally transmits the on-site data to an external server. Because the second industrial computer 600 obtains the encrypted data graph in a contactless manner, the information obtained by the second industrial computer 600 can be securely transmitted to the server. The overall structure of the visually isolated data acquisition terminal is also relatively inexpensive to implement. The camera 500 can be shifted within a vertical two-dimensional plane to capture images at different positions on the display screen 300.

[0047] Reference Figures 1 to 5 In one embodiment, the visual isolation data acquisition terminal further includes a tray 700 supported and arranged in the middle of the height direction of the box body 100, and a shock-absorbing pad is provided in the thickness direction at the connection position between the tray 700 and the box body 100, and the first industrial computer 200 and the second industrial computer 600 are installed on the tray 700.

[0048] In this embodiment, the tray 700 serves as a supporting base for the first industrial computer 200 and the second industrial computer 600. Vibration transmitted to the tray 700 in the thickness direction is buffered by the provision of shock-absorbing pads. The material of the shock-absorbing pads can be various types of rubber materials. During the specific installation process, the tray 700 is mounted on the box body 100 by multiple bolts, and shock-absorbing pads are added between the bolts and the tray 700. The material of the shock-absorbing pads can be various types of rubber materials. The buffering effect provided by the shock-absorbing pads reduces the possibility of the first industrial computer 200 and the second industrial computer 600 being impacted during transfer and operation and thus experiencing abnormal operation.

[0049] Reference Figures 1 to 5 In one embodiment, the first industrial computer 200 and the tray 700 are provided with shock-absorbing pads in the thickness direction, and the second industrial computer 600 and the tray 700 are provided with shock-absorbing pads in the thickness direction.

[0050] In this embodiment, vibrations transmitted to the first and second IPCs 200 and 600 in the thickness direction are dampened by the provision of shock-absorbing pads. The shock-absorbing pads can be made of various types of rubber. During installation, using the first IPC 200 as an example, the first IPC 200 is mounted to the tray 700 using multiple bolts, with shock-absorbing pads placed between the bolts and the tray 700. The cushioning provided by the shock-absorbing pads reduces the likelihood of operational abnormalities caused by impacts during transfer and operation between the first and second IPCs 200 and 600.

[0051] In one embodiment, the display screen 300 is installed on an inner peripheral wall of one side of the box body 100 , and the inner wall of the box body 100 other than the display screen 300 is coated with a light absorbing layer or is installed with a light absorbing sheet.

[0052] Considering that the inner wall of the housing 100 is prone to light reflection, which can weaken the image displayed on the display screen 300 and reduce the accuracy of the image captured by the camera 500, a light-absorbing layer is applied to the inner wall of the housing 100 or a light-absorbing sheet is installed. This prevents light emitted by the display screen 300 from causing adverse light reflections on the inner wall of the housing 100. The light-absorbing layer and light-absorbing sheet are made of black material to achieve a light-absorbing effect.

[0053] In one embodiment, the outer surface of the light absorbing layer or the light absorbing sheet has a matte finish.

[0054] In this embodiment, considering that flat black materials still reflect light to a certain extent, a matte finish can be applied to the surface to further reduce this reflection, for example by adding micro-bumps or micro-pores. Specifically, adding micro-bumps to the light-absorbing layer is convenient, while adding micro-pores to the light-absorbing sheet is convenient. Through the above matte finish, the reflection effect is further reduced.

[0055] In one embodiment, the housings of the first industrial computer 200, the second industrial computer 600, the camera 500 and the mounting bracket 400 are coated with a light absorbing layer or installed with a light absorbing sheet, and the outer surface of the light absorbing layer or the light absorbing sheet has a matte finish.

[0056] In this embodiment, the optical environment inside the box 100 is optimized, and several larger structures are subjected to reflective optimization treatment. Correspondingly, relevant coatings can also be applied to the periphery of each connecting cable, so that the negative impact of all components in the box 100 on the operation of the camera 500 is minimized.

[0057] In one embodiment, a fill light is provided in the box 100 .

[0058] In this embodiment, the optical environment in the box 100 can be adjusted by the fill light, so that the camera 500 can optimize the collection of information displayed on the display screen 300. The specific type and number of the fill light can be adjusted according to the use requirements.

[0059] In one embodiment, the box body 100 is made of cold-rolled steel plate.

[0060] In this embodiment, a material for the box body 100 is proposed, which has mature technology and satisfactory performance, has the advantages of low cost and high strength, and can protect relevant components in the box body 100.

[0061] In one embodiment, the vertical support 420 is an electric push rod type.

[0062] In this embodiment, the vertical bracket 420 is a structure of an electric push rod, thereby achieving telescopic action.

[0063] Reference Figures 1 to 5 In one embodiment, both ends of the transverse bracket 410 in the length direction are passed through the box body 100.

[0064] In this embodiment, both ends of the transverse bracket 410 extend beyond the box body 100 , and the sliding structure is simple and easy to operate, thus facilitating sliding adjustment.

[0065] In summary, the visual isolation data acquisition terminal provided by the present invention has a first industrial computer 200 connected to the on-site equipment via a wired connection, has no signal transmitter, and has no risk of intrusion. The second industrial computer 600 realizes contactless data transmission with the first industrial computer 200 through the camera 500. After the second industrial computer 600 identifies the data graph displayed on the display screen 300 in a contactless manner through the camera 500, it obtains the on-site data after being parsed by the graphic transmission system. The second industrial computer 600 finally transmits the on-site data to an external server. Since the second industrial computer 600 obtains the encrypted data graph in a contactless manner, the information obtained by the second industrial computer 600 can be securely transmitted to the server. The overall structural implementation cost of the above visual isolation data acquisition terminal is also relatively low. The camera 500 can realize position transfer within a vertical two-dimensional plane to meet the image acquisition requirements for different positions of the display screen 300.

[0066] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention.
