[0044] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0045] First, the application scenario of the present disclosure is introduced. The present disclosure is applied in the scenario of display control of production equipment. The process parameters of production equipment are often displayed through the display of production equipment to facilitate user viewing and operation. However, any user can view the display information of the display, which is easy to cause the leakage of process parameters and thus cause economic losses.

[0046] In the prior art, users are required to pay attention to the display and surrounding environment of the production equipment in real time to prevent other people from approaching and avoid information leakage. However, manual information protection consumes a lot of human resources, is prone to errors, and has low work efficiency.

[0047] In order to solve the above problems, the present disclosure provides a control method and system for a display, the system comprising an electronic tag, an RDIF reader, a controller, a target video switch and a display; the electronic tag is connected to the RDIF reader; the RDIF reader is connected to the controller; the controller is connected to the target video switch; the target video switch is connected to the display; the RDIF reader is used to obtain user information sent by the electronic tag; the controller is used to determine the target video switch when it is determined that the user information is authorized user information; the target video switch is used to control the display to display display information; through the above technical solution, the display information can be displayed when it is determined that the user is an authorized user, thereby avoiding information leakage caused by unauthorized users viewing the display information, improving the safety of the production process, and reducing economic losses.

[0048] Figure 1 FIG. 1 is a block diagram of a display control system 100 according to an exemplary embodiment. Figure 1 As shown, the system includes an electronic tag 110, an RDIF reader 120, a controller 130, a target video switch 140 and a display 150; the electronic tag 110 is connected to the RDIF reader 120; the RDIF reader 120 is connected to the controller 130; the controller 130 is connected to the target video switch 140; the target video switch 140 is connected to the display 150;

[0049] The RDIF reader 120 is used to obtain the user information sent by the electronic tag 110 .

[0050] For example, the electronic tag may be an RDIF tag, which may be set at a preset position of the user's tooling. The user information may include a variety of information, for example, one or more of the user's avatar, name, or position, and the user information may also be represented by a digital code.

[0051] In some embodiments, the RDIF reader 120 may be used to obtain the user information sent by the electronic tag 110 when the user information is within a preset range.

[0052] For example, the preset range may be an area centered on the production equipment, and the area may be a sector, a circle, or a rectangle, etc., which is not limited here. For example, when the preset range is a circular area, the diameter of the preset range may be in the range of 0.5m-1.5m. In this way, when the user is within the preset range, the user information of the user may be directly obtained; and the user information may be quickly obtained through the electronic tag for user login, which reduces the cumbersome steps of logging in through an account and improves work efficiency.

[0053] The controller 130 is used to determine the target video switch 140 when it is determined that the user information is authorized user information.

[0054] For example, the controller may be a computer switch (Keyboard, Video, Mouse Switch, KVMSwitch) for controlling multiple computers or production equipment.

[0055] In some embodiments, the controller 130 is used to determine that the user information is authorized user information when the user information successfully matches the preset user information in the preset correspondence; the preset correspondence is a correspondence between multiple user information and multiple preset user information, and each user information corresponds one-to-one with each preset user information.

[0056] For example, the user information and the preset user information may include multiple types of information; for example, one or more types of information such as a user's avatar, name, or position may be included. In other embodiments, the user information may be determined to be authorized user information when one type of information in the user information successfully matches one type of information in the preset user information. Alternatively, the user information may be determined to be authorized user information when multiple types of information in the user information successfully matches multiple types of information in the preset user information. Through the above technical solution, the user identity can be determined, and the authorized user and the unauthorized user can be clearly identified, thereby improving work efficiency.

[0057] In some embodiments, the controller 130 is used to determine the target video switch 140 corresponding to the user information from a plurality of video switches.

[0058] For example, the controller can control multiple video switches; the video switch can be set on the production equipment, so as to realize the control of multiple production equipment in the target area through the controller, thereby improving work efficiency. Through the above embodiment, the correspondence between users and production equipment can be realized, avoiding users from operating other production equipment by mistake, and improving the safety of the production process.

[0059] The target video switch 140 is used to control the display 150 to display information.

[0060] For example, the displayed information may include process parameters of production equipment, production information, equipment information or user information, etc., which are not limited here.

[0061] Through the above technical solution, display information can be displayed when it is determined that the user is an authorized user, avoiding information leakage caused by unauthorized users viewing the display information, improving the safety of the production process, and reducing economic losses.

[0062] In some embodiments, the target video switch 140 is used to switch the transmission between the target video switch 140 and the display 150 to a connected state, so that the display 150 displays the display information.

[0063] For example, the target video switch is used to control the signal transmission between the target video switch and the display; for example, the transmission between the target video switch and the display can be switched to a connected state; or, the transmission between the target video switch and the display can be switched to an interrupted state. In this way, when it is determined that the user is an authorized user, the display can be controlled to display information, which is convenient for the authorized user to view and operate, while saving the tedious steps of user login and improving work efficiency.

[0064] In some other embodiments, the controller 130 is further configured to control the display 150 to stop displaying the display information through the target video switch 140 when it is determined that the user information is unauthorized user information.

[0065] For example, the target video switcher can be used to switch the transmission between the target video switcher and the display to an interrupted state. In this way, when an unauthorized user approaches, the display can directly stop displaying the display information, preventing the unauthorized user from viewing production-related content, thereby improving the safety of the production process.

[0066] In some embodiments, the controller 130 is further configured to issue an alarm message when determining that the user information is unauthorized user information.

[0067] In other embodiments, the controller may include an alarm device; when the controller determines that the user information is unauthorized user information, the controller may issue an alarm message through the alarm device.

[0068] For example, the warning information may be audio information, text information, or light information, etc. In this way, when an unauthorized user approaches the display, an alarm may be given in time, without the need to manually monitor the display, production equipment, and surrounding environment, thereby improving work efficiency. 。

[0069] Figure 2 is based on Figure 1 A block diagram of a display control system is shown in FIG. Figure 2 As shown, the system 100 further includes a server 160 ; the server 160 is connected to the controller 130 ; the controller 130 is used to generate an access record according to the user information and store the access record in the server 160 .

[0070] For example, the server may include one or more servers. In this way, when a problem occurs, it can be traced in time through access records, thereby improving the efficiency of problem handling.
