In order to make the objects, technical solutions and advantages of the present application more apparent, the following detailed description of the embodiments of the present application will be given with reference to the accompanying drawings.
When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application as detailed in the accompanying claims.

The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art. Furthermore, in the description of the present application, unless otherwise indicated, "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.
In the existing screen projection technology, a wireless communication screen projection technology based on the same local area network is mostly used. When the transmitting (screen-throwing) device and the receiving (screen-throwing) device are in the same local area network, the screen throwing of the transmitting device to the receiving device can be realized through a screen throwing protocol. Among them, the screen projection protocol includes AirPlay protocol, digital living network alliance (Digital Living Network Alliance, DLNA), miracast protocol, and the like.
Whatever protocol is used, when the sending device and the receiving device are under the same lan, the screen-casting connection is maintained if there is no other operation. However, if the user forgets to close the screen, the screen-throwing connection will not be broken as long as the sending device and the receiving device are under the same local area network, and the screen-throwing information will be retained in the receiving device. In this way, especially in important occasions such as business meetings, the problem of leakage of screen projection information is easily caused.
The application provides a screen projection control method and device, a computer readable storage medium and a terminal. Hereinafter, each step of the screen projection control method in the present example embodiment will be described in more detail with reference to the accompanying drawings and examples.
Fig. 1 schematically illustrates an information interaction diagram of a screen-projection control method according to an exemplary embodiment of the present application. Referring to fig. 1, the embodiment shown in fig. 1 is described in detail below:
in S11, the second device 120 transmits the second identification code to the first device 110.
In an exemplary embodiment, the first device 110 may be a device capable of receiving a screen and displaying screen information, such as a computer, television, tablet, etc., and the second device 110 may be a cell phone, computer, tablet, etc. The first device 110 and the second device 120 are required to be under the same lan if they are connected to each other.
In an exemplary embodiment, after the first device 110 connects to the same local area network as the second device 120, the second device 120 needs to pair with the first device 110 through the screening software therein. The second device 120 sends a second identification code to the first device 110, where the second identification code includes information corresponding to the second device 120, for example, device information, holder information, etc., and the application is not limited thereto, and each second identification code only corresponds to one second device 120.
In an exemplary embodiment, taking a meeting room scenario as an example, the first device 110 may be a conference tablet and the second device 120 may be a computer. The conference staff A brings the computer into the conference room, and after the computer and the conference flat board are connected with the same local area network, the second identification code (assuming that the name of the conference staff A and the equipment ID of the computer are stored in the second identification code) in the computer can be sent to the conference flat board through screen throwing software in the computer.
In S12, the first device 110 receives the second identification code sent by the second device 120, and matches the second identification code with the first identification code of the first device 110.
In S13, if the second identification code matches the first identification code successfully, the first device 110 establishes a screen transfer service connection with the second device 120.
In an exemplary embodiment, after receiving the second identification code sent by the second device 120, the first device 110 matches the first identification code in the first device 110, and if the matching is successful, the first device 110 can establish a screen-transfer service connection with the second device 120.
In an exemplary embodiment, taking a meeting room scenario as an example, after the meeting flat receives the second identification code sent by the computer of the meeting person a, if the first identification code in the meeting flat is successfully matched with the second identification code, the meeting person a can select to screen the content in the computer to the meeting flat.
In S14, the identification tag configured in the second device is detected by the radio frequency identification module.
In an exemplary embodiment, the first device 110 is configured with a radio frequency identification module. Radio frequency identification (Radio Frequency Identification, RFID) refers to the transmission of digital IDs and other data between an RFID tag and a reader/writer in a wireless or contactless manner by electromagnetic waves. Each RFID-tagged item can be seamlessly identified, verified, tracked, detected, and interacted with by a unique digital ID. Unlike other automatic identification techniques such as optical two-dimensional codes, RFID can read tags in a line of sight range of several centimeters to 20 meters, with the specific range depending on the type of RFID. The application adopts an ultra-high frequency radio frequency identification (RFID-UHF) module to realize detection. At present, the RFID-UHF technology is very mature, adopts the ISO18000-6C protocol, supports an anti-collision detection algorithm, can identify a high-speed moving object, and can simultaneously identify a plurality of tags. RFID-UHF identification has the characteristics of nondirectionality, batch identification, long service life, pollution resistance and the like.
In the exemplary embodiment, the radio frequency identification is mainly implemented by three parts, namely: tag, reader, and Antenna. The tag consists of a coupling element and a chip, each tag has a unique electronic code, stores data information of a target object, and is attached to the object to identify the target object. Illustratively, the electronic code in the tag holds information about the properties, status, number, etc. of the target object. The tag is usually arranged on the surface of the target object, so that the reader-writer and the antenna can conveniently detect and identify the tag; the reader-writer is used for reading (sometimes also writing) tag information, can be designed as a handheld type or a fixed type, and has the main functions of: reading data information currently stored in the tag, writing data information to be stored in the blank tag, and modifying (rewriting) the data information in the tag; the antenna is used to transfer radio frequency signals between the tag and the reader.
In an exemplary embodiment, the RFID module configured by the first device 110 may be the RFID-UHF module, and in general, the driving power of the reader-writer may reach 28dbm or more, and the receiving sensitivity is less than-75 dbm. Referring to the schematic diagram of the antenna arrangement shown in fig. 2, by way of example, taking two antennas as an example (the number of antennas is not particularly limited in the present application), the antennas may be placed in front of the first device 110 (profile aperture installation) using two 80 x 80mm 6dbi (dbi, antenna gain) circularly polarized ceramic antennas.
In the exemplary embodiment, only one antenna is in a working state at the same time, so when a plurality of antennas are configured, a radio frequency switch can be additionally configured to control the antennas, so that the antennas perform rotation work, and the antennas can cover dead zones with shorter distances from the first device 110 as much as possible.
In an exemplary embodiment, taking a conference room scenario as an example, reference is made to a schematic diagram of screen-drop control in the conference room scenario shown in fig. 3. The front end of the conference flat plate is provided with two antennas to form an identification area (i.e. a detection area) as shown in fig. 3, and compared with one antenna, the two antennas have wider detection range and can cover the whole conference room and blind areas difficult to detect as much as possible.
In an exemplary embodiment, a tag needs to be configured in addition to a reader and an antenna. In the present application, the target object to be detected is the second device 120, and therefore, the corresponding identification tag is configured outside the second device 120. The identification tag may be formed by a coated paper tag or the like, and may be fixed to the outside of the second device 120, and the present application is not limited thereto. In addition, when the tag is fixed, it is preferable to fix the tag at a position where the possibility of being detected by the antenna is high according to the specific orientation of the second device 120 in the detection area, so as to improve the accuracy of the detection result.
In an exemplary embodiment, the data information stored in the identification tag of the second device 120 and the data information in the second identification code transmitted by the second device 120 need to be the same, so that the reader/writer can detect whether the second device 120 corresponding to the second identification code having the same information is in the detection area according to the information in the read identification tag. For example, the second identification code stores the device ID and the name of the holder of the second device 120, and the identification tag of the second device 120 should also store the same device ID and the name of the holder. The reader-writer can read information of the identification tag at regular time according to a certain preset time interval.
In an exemplary embodiment, taking a meeting scenario as an example, an identification tag is attached to a front cover of a computer held by the meeting participant a, and the name of the meeting participant a and ID information of the computer are stored in the identification tag, so that the identification tag should be identical to information in a second identification code sent by the computer of the meeting participant a. Thus, the identification tag in the computer can always keep the screen-throwing state as long as the identification tag is in the detection area in the conference room.
In S15, if it is detected that the identification tag configured in the second device is not in the detection area, the screen-on connection with the second device is disconnected.
In an exemplary embodiment, if the antenna and reader do not detect the presence of the second device 120, the first device 110 automatically disconnects the screen from the second device 120.
In an exemplary embodiment, taking a meeting room scenario as an example, if the meeting participant a leaves the meeting room with the computer before closing the screen connection, the antenna and the reader-writer cannot identify and read the identification tag in the computer of the meeting participant a, and then the meeting panel automatically disconnects the screen connection with the computer, so that information leakage of the screen content can be prevented.
In the exemplary embodiment, taking the meeting room scenario as an example, in addition to detecting the computers of meeting personnel a, the devices (computers) of other members in the meeting room may also be detected. Because each computer corresponds to a unique identification tag, the timing identification detection of the conference participants can be realized through the antenna and the reader-writer so as to record the presence condition of the conference participants.
It should be noted that, the conference room scenes listed in the above embodiments are only examples, and the screen projection control method provided by the present application may also be used in other scenes, which is not limited herein.
The screen-throwing control method provided by the self can detect the screen-throwing equipment through the wireless radio frequency identification module, and when the screen-throwing equipment is outside the detection area, the screen-throwing receiving equipment provided with the wireless radio frequency identification module can automatically disconnect the screen-throwing connection so as to avoid the leakage of screen-throwing information. In addition, other devices in the detection area can be detected, and a function of timing recording of the presence condition of the other devices is realized.
