Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The application provides a remote information data consulting method based on a remote control technology, which is applied to a remote control management system. Wherein, this remote control management system includes: the remote control system comprises a remote control server, a to-be-controlled terminal cluster and control terminals, wherein the to-be-controlled terminal cluster comprises a plurality of to-be-controlled terminals, each to-be-controlled terminal comprises a host and a display, the host is connected with the remote control server, the host is provided with a virtual display card and an entity display card, and the display is connected with the host through the entity display card. Optionally, the remote control management system may be set for a medical institution, the cluster of terminals to be controlled may be a cluster formed by office computers used by various inspectors inside the institution, and the control terminal may be a mobile computer used by the inspectors when going out.
In one scenario, when the inspector se:Sub>A goes on se:Sub>A business trip and needs to remotely control the office computer PC-se:Sub>A in the mechanism to look up the datse:Sub>A, the office computer PC-se:Sub>A is the above-mentioned terminal to be controlled, and the terminal to be controlled is configured with the virtual display card and the physical display card, wherein the display is connected with the host through the physical display card. The method is characterized in that the office computer PC-A is provided with se:Sub>A virtual display card and an entity display card, so that two paths of display signals can be output, and the requirements of successful consultation of the mobile computer PC-A' and corresponding safety display on se:Sub>A display of the office computer PC-A can be met when datse:Sub>A of different safety levels are consulted.
For example, when the security level is low, the display of the office computer PC-se:Sub>A and the display of the mobile computer PC-se:Sub>A 'both display the actual datse:Sub>A to be referred, so that while the requirement of the mobile computer PC-se:Sub>A' for successful reference is met, others can be requested to assist the office computer PC-se:Sub>A during the reference process. When the security level is higher, the mobile computer PC-A 'displays the actual datse:Sub>A to be consulted, and the office computer PC-A display displays the processed datse:Sub>A, so that the requirement of successful consultation of the mobile computer PC-A' is met, and meanwhile, datse:Sub>A leakage can be avoided in the consultation process. In addition, if desensitization datse:Sub>A corresponding to the datse:Sub>A part displayed by the display of the office computer PC-A is detected, normal display of other functional areas of the interface can be ensured besides datse:Sub>A leakage is avoided in the process of consulting, so that other people can be requested to assist the office computer PC-A in the process of consulting, for example, when the remote control network speed is slow and the remote control cannot be effectively carried out, other people can be requested to carry out page turning operation on the current page of the office computer PC-A. It is worth understanding that when the remote control network is slow, if a user needs to trigger a corresponding control component during remote control, the component cannot be located, and the triggering cannot be successfully performed after the triggering, so that in this case, the remote control often fails, but there is often only a delay in displaying the page content. Therefore, in this case, if the user cannot perform remote page turning, the user may request another person to perform se:Sub>A page turning operation on the current page of the office computer PC-se:Sub>A, and then the actual datse:Sub>A after page turning may be displayed on the mobile computer PC-se:Sub>A', while only the processed datse:Sub>A may be displayed on the display of the office computer PC-se:Sub>A.
