It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should also be noted that, for the convenience of description, only some but not all of the matters related to the present invention are shown in the drawings. It should be further noted that, for convenience of description, examples related to the present invention are shown in the following embodiments, which are used only for illustrating the principles of the embodiments of the present invention and are not meant to limit the embodiments of the present invention, and the specific values of the examples may vary according to different application environments and parameters of the apparatus or the components.

Example one

Fig. 1 is a schematic flowchart of a connection method for a wireless screen transmission device according to an embodiment of the present invention. The method is applicable to the case of wireless connection, and the method can be executed by a wireless screen transmission connection device, which can be composed of hardware and/or software, and can be generally integrated in a wireless screen transmission device and all terminals containing screen transmission functions. The method specifically comprises the following steps:

s110, searching and acquiring a wireless hotspot name of the target display device according to the preset field, wherein the wireless hotspot name comprises the preset field and a coding field.

The preset field may be an identification field of the wireless hotspot, which is set according to the factory of the display device, and thus, the preset field may be fixed and unchangeable for the same target display device or the same type of display device. Specifically, the searching for the wireless hotspot of the target display device according to the preset field is to shield the interference of the wireless hotspot of other devices, and to automatically obtain the name of the wireless hotspot of the target display device.

The target display device can be an intelligent terminal such as an interactive flat panel and an intelligent white board, and the intelligent terminal has a wireless hotspot function and a screen transmission supporting function. For example, a preset field in an SSID "seewo _ 1234567" sent by the interactive tablet is "seewo", and when the wireless screen-transmitting device searches that there is a "seewo" field in the names of wireless hotspots within the receiving range, the SSID of the wireless hotspot is obtained, where "1234567" is an encoding field.

And S120, determining a wireless hotspot login password of the target display equipment according to the encoding field of the wireless hotspot.

Specifically, the encoding field of the wireless hotspot may be set after the preset field, and together with the preset field, the encoding field may form a wireless hotspot name of the target display device, and the encoding field may be a series of characters obtained by encrypting the wireless hotspot login password of the target display device through an encryption algorithm. Wherein the wireless hotspot login password and/or the encryption algorithm may be dynamically changed. The purpose of setting the coding field is to only allow a specific device to be connected with the wireless hotspot of the target display device, so that the situation of error connection caused by automatic connection when other devices such as a mobile phone enter the range of the wireless hotspot for the second time after being connected with the target display device is avoided.

Specifically, the process of determining the wireless hotspot login password of the target display device according to the encoding field of the wireless hotspot may be a process of decrypting the encoding field, which is opposite to a process of encrypting the wireless hotspot login password by the target display device using an encryption algorithm. Illustratively, the interactive panel encrypts the wireless hotspot login password by using an encryption algorithm to form an encoding field, and the wireless screen transmission device decrypts the wireless hotspot login password by using a decryption algorithm corresponding to the encryption algorithm according to the encoding field carried in the wireless hotspot name to obtain the wireless hotspot login password of the interactive panel.

And S130, establishing wireless connection with the target display equipment according to the wireless hotspot name and the wireless hotspot login password.

Specifically, according to the wireless hotspot name of the target display device acquired in the receiving range and the decrypted wireless hotspot login password of the target display device, the wireless connection with the target display device can be automatically completed.

Illustratively, after the wireless screen transmission device is connected with a computer through a Universal Serial Bus (USB) interface, the wireless screen transmission device can establish wireless connection with the interactive tablet by using the acquired wireless hotspot name of the interactive tablet and the decrypted wireless hotspot login password of the target display device, so that the computer screen is transmitted to the interactive tablet through the wireless connection, the interactive tablet can display the computer screen, and the screen transmission process is completed.

According to the technical scheme, the wireless hotspot name of the target display equipment is obtained according to the preset field, and the wireless hotspot login password is determined according to the coding field in the wireless hotspot name, so that the wireless connection with the target display equipment is established, the problems that the operation is inconvenient and other equipment cannot be automatically prevented from being mistakenly connected due to the fact that the wireless hotspot password needs to be manually set in the prior art are solved, the pairing operation is simplified, and the effect of preventing other equipment from being mistakenly connected is achieved.

Example two

Fig. 2 is a schematic flowchart of a connection method for a wireless screen transmission device according to a second embodiment of the present invention. The present embodiment is optimized based on the above embodiments, and provides a preferred connection method for a wireless screen transmission device, specifically, searching and acquiring a wireless hotspot name of a target display device according to a preset field includes: searching for wireless hotspot names within the connection range; and acquiring the name of the wireless hotspot containing the preset field.

And S210, searching the wireless hotspot name in the connection range.

Specifically, the connection range is related to the receiving range of the terminal and the wireless hotspot sending range of the target display device. When searching for a wireless hotspot, a plurality of wireless hotspot names may appear in the connection range, and at this time, the wireless hotspot names may be arranged according to the signal intensity of the wireless hotspot.

S220, acquiring the wireless hotspot name containing the preset field.

Specifically, if only one wireless hotspot name containing a preset field is found in the connection range, the wireless hotspot name is directly obtained; and if at least two wireless hotspot names containing the preset fields are searched in the connection range, acquiring the wireless hotspot name containing the preset fields and having the maximum signal intensity.

For example, if the wireless screen transmission device searches that only one SSID containing "seewo" exists in the connection range, the SSID of the interactive panel corresponding to the wireless hotspot is obtained; and if the wireless screen transmission equipment searches that two SSIDs containing 'seewo' exist in the connection range, acquiring the SSID of the interactive panel corresponding to the wireless hotspot with higher signal intensity.

And S230, determining a wireless hotspot login password of the target display equipment according to the encoding field of the wireless hotspot.

S240, establishing wireless connection with the target display device according to the wireless hotspot name and the wireless hotspot login password.

According to the technical scheme, the wireless hotspot name in the connection range is searched, the wireless hotspot name containing the preset field is obtained, and the wireless hotspot login password is determined according to the coding field in the wireless hotspot name, so that the wireless connection with the target display equipment is established, the problems that in the prior art, the operation is inconvenient due to the fact that the wireless hotspot password needs to be manually set, and the misconnection of other equipment cannot be automatically prevented are solved, the pairing operation is simplified, and the misconnection of other equipment is prevented.

EXAMPLE III

Fig. 3 is a schematic flowchart of a connection method for a wireless screen transmission device according to a third embodiment of the present invention. The present embodiment is optimized based on the foregoing embodiments, and provides a preferred connection method for a wireless screen transmission device, specifically, further optimizing a wireless hotspot login password for determining a target display device according to an encoding field of a wireless hotspot, includes: acquiring an encoding field in the name of the wireless hotspot, wherein the encoding field is obtained by encoding the login password of the wireless hotspot according to a preset encoding mode; and decoding the coded field according to a decoding mode corresponding to the preset coding mode, and determining the decoded field as the wireless hotspot login password of the target display equipment.

S310, searching and acquiring a wireless hotspot name of the target display device according to the preset field, wherein the wireless hotspot name comprises the preset field and a coding field.

S320, obtaining an encoding field in the name of the wireless hotspot, wherein the encoding field is obtained by encoding the login password of the wireless hotspot according to a preset encoding mode.

Optionally, the preset field and the encoding field in the wireless hotspot name are connected by a certain identifier, for example, the wireless hotspot name is 16 bits, the first 5 bits are the preset field, i.e., "seewo", the last 10 bits are the encoding field, i.e., "0123456789", and an underline is arranged between the preset field and the encoding field, so that the wireless hotspot name is "seewo _ 0123456789", i.e., the encoding field in the hotspot name can be determined and obtained according to the identifier.

Specifically, the preset encoding mode may be fixed, that is, an encryption algorithm that is set when the target display device leaves the factory, for example, the preset encoding mode may be a simple shift algorithm or an addition, subtraction, multiplication, and division algorithm, or may be a special encryption algorithm, the number of bits of the encoded field obtained after encryption only needs to meet a preset required number of bits, and the specific type of the algorithm is not limited herein. And the coding field is a special field obtained by coding the wireless hotspot login password according to the preset coding mode. For example, when the wireless hotspot login password is "0123456789" and the preset encoding manner is to circularly shift by one bit to the right, the encoding field is "9012345678".

S330, decoding the coded field according to a decoding mode corresponding to the preset coding mode, and determining the decoded field as a wireless hotspot login password of the target display equipment.

Correspondingly, the decoding mode is the inverse operation of the encoding mode, the encoding field is decoded, and the wireless hotspot login password of the target display equipment can be obtained through the inverse operation of the encoding mode. For example, if the encoding field is "9012345678" and the predetermined encoding manner is circularly shifted by one bit to the right, the decoding manner is circularly shifted by one bit to the left, and thus the decoded field is "0123456789", which is the wireless hotspot login password of the interactive tablet.

Specifically, since the wireless hotspot login password is randomly variable for the same target display device, the encoding field is also changed along with the change of the wireless hotspot login password, that is, compared with other devices that need to be connected to the target display device, the wireless connection with the target display device cannot be directly established through the history login record.

S340, establishing wireless connection with the target display device according to the wireless hotspot name and the wireless hotspot login password.

According to the technical scheme, the wireless hotspot name of the target display equipment is obtained according to the preset field, the coding field obtained from the wireless hotspot name is decoded according to the decoding mode corresponding to the preset coding mode, and the wireless hotspot login password is obtained, so that the wireless connection with the target display equipment is established, the problems that in the prior art, due to the fact that the wireless hotspot password needs to be manually set, operation is inconvenient, and other equipment cannot be automatically prevented from being mistakenly connected are solved, the pairing operation is simplified, and the effect of preventing other equipment from being mistakenly connected is achieved.

Example four

Fig. 4 is a schematic flowchart of a connection method for a wireless screen transmission device according to a fourth embodiment of the present invention. The present embodiment is optimized based on the above embodiments, and provides a preferred connection method for a wireless screen transmission device, specifically, a wireless hotspot name is further optimized to include an encoding mode field.

S410, searching and acquiring a wireless hotspot name of the target display device according to the preset field, wherein the wireless hotspot name comprises a preset field, a coding field and a coding mode field.

Specifically, the encoding mode field may be set in the name of the wireless hotspot together with a preset field and an encoding field, and the preset field, the encoding mode field, and the encoding field are connected by an identifier, for example, for a SSID with 16 bits in the interactive tablet, the preset field, the encoding mode field, and the encoding field are connected by underlining, that is, the SSID is "seewo _ a _ 81234567", wherein the preset field is "seewo", the encoding mode field is "a", and the encoding field is "81234567".

And S420, acquiring the coding mode field and the coding field in the wireless hotspot name.

The encoding field is obtained by encoding the wireless hotspot login password according to the specific encoding mode.

Specifically, the encoding mode field may be set as an identifier of a specific encoding mode, that is, one encoding mode field corresponds to one encoding mode, for example: if the coding mode field is set to be 'a', the coding mode is circularly shifted by one bit to the right; if the coding mode field is set to "b", it indicates that the coding mode is circularly shifted by two bits to the right.

Specifically, the encoding mode field may be dynamically changed along with the restart of the target display device, that is, the same display device may set different encoding mode fields and respectively correspond to different encoding modes, and the encoding mode field is changed along with the restart of the display device.

And S430, decoding the coded field according to a decoding mode corresponding to the specific coding mode, and determining that the decoded field is the wireless hotspot login password of the target display equipment.

Specifically, the encoded field is decoded according to an inverse operation of a specific encoding method corresponding to the encoding method field. For example, if the encoding mode field in the SSID "seewo _ a _ 81234567" of the interactive tablet is set to "a" and the corresponding specific encoding mode is circularly shifted by one bit to the right, when the wireless screen-transfer device decodes the acquired encoding field "81234567", the wireless screen-transfer device circularly shifts by one bit to the left according to the decoding mode corresponding to the specific encoding mode to obtain a decoded field "12345678", and at this time, it may be determined that the wireless hotspot login password of the interactive tablet is "12345678". The advantage of setting up the coding mode field lies in, even the wireless hotspot login password of target display device is not dynamic change, because the decoding mode is dynamic change, also can generate different wireless hotspot login names, thereby avoid the condition that other devices cause misconnection through historical login records, and simultaneously, the special device such as wireless screen transmission device which needs to be connected with the target display device can not establish wireless connection only because of the complex operations such as manual login and the like caused by the dynamic change of the wireless hotspot login password, thereby simplifying the operation of establishing wireless connection between the special device and the target display device.

S440, establishing wireless connection with the target display device according to the wireless hotspot name and the wireless hotspot login password.

According to the technical scheme, the encoding mode field and the encoding field in the wireless hotspot name sent by the target display equipment are obtained, the encoding field is decoded according to the decoding mode corresponding to the specific encoding mode represented by the encoding mode field, and the wireless hotspot login password is obtained, so that the wireless connection with the target display equipment is established, the problems that in the prior art, due to the fact that the wireless hotspot password needs to be manually set, operation is inconvenient, and other equipment cannot be automatically prevented from being connected by mistake are solved, the pairing operation is simplified, and the effect of preventing other equipment from being connected by mistake is achieved.

Illustratively, during the restarting process of the interactive tablet, a set of random numbers, for example, "12345678," is dynamically generated, an encoding field "78123456" is generated according to a preset encoding manner, for example, the password is circularly moved by two bits to the right, the preset field "seewo" and the encoding field "78123456" are connected by underlining, and the SSID of the interactive tablet, that is, "seewo _78123456," is generated. Optionally, the wireless hotspot name further includes an encoding mode field "a", and the generated SSID is "seewo _ a _ 78123456". The coding modes corresponding to the coding mode fields can be correspondingly stored by establishing a coding database, and when the display equipment is restarted, the corresponding wireless hotspot names are generated by calling the coding database according to the different coding mode fields. Correspondingly, the same decoding database corresponding to the encoding mode field is also arranged at the wireless screen transmission equipment end, and the encoding mode and the decoding mode stored in the encoding database and the decoding database are mutually inverse operations under the condition that the encoding mode field is the same.
