All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a flow chart of a method for sharing data between multiple mobile terminals based on digital asset management according to an embodiment of the present invention is shown. The multi-mobile terminal data sharing method based on digital asset management comprises the following steps:
step S1, respectively sending a connection request instruction to a plurality of mobile terminals, and obtaining a feedback message of each mobile terminal about the connection request instruction; analyzing the feedback information to determine the current position information and the data demand information of each mobile terminal;
step S2, according to the current position information of each mobile terminal, determining the corresponding mobile terminal as a mobile terminal capable of sharing data and a mobile terminal incapable of sharing data; according to the data demand information of the mobile terminal which can share the data, determining the multimedia data which is actually required to be acquired;
Step S3, according to the multimedia data acquired in actual need, searching corresponding multimedia data from the digital asset management server; and then the found multimedia data are sequentially subjected to format conversion processing and packaging processing and then are transmitted to the corresponding mobile terminal capable of sharing data.
The beneficial effects of the technical scheme are as follows: the multi-mobile terminal data sharing method based on digital asset management can ensure that the digital asset management server can simultaneously perform data sharing with a plurality of mobile terminals, and can also perform data query by taking the image content of video and/or pictures as a search basis, so that the searchable range of the video and/or pictures can be enlarged, and the searching efficiency and accuracy of the video and/or pictures can be improved.
Preferably, in the step S1, a connection request instruction is sent to a plurality of mobile terminals, respectively, and a feedback message of each mobile terminal about the connection request instruction is obtained; analyzing the feedback message to determine the current location information and data requirement information of each mobile terminal specifically includes:
step S101, periodically sending a connection request instruction to a plurality of mobile terminals through a digital asset management server, and determining the waiting time length corresponding to the feedback message of each mobile terminal about the connection request instruction received by the digital asset management server; the waiting time length refers to the time length from the time when the digital asset management server sends a connection request instruction to the mobile terminal until the digital asset management server receives a corresponding feedback message;
Step S102, comparing the waiting time length with a preset time length threshold; if the waiting time length is greater than or equal to a preset time length threshold, stopping sending a connection request instruction to the corresponding mobile terminal; if the waiting time length is smaller than the preset time length threshold, continuing to periodically send a connection request instruction to the corresponding mobile terminal until the feedback message is obtained;
and step S103, analyzing the feedback information so as to obtain GPS position information and data type requirement information of the corresponding mobile terminal.
The beneficial effects of the technical scheme are as follows: the plurality of mobile terminals can be connected with the digital asset management server through a wireless network; the mobile terminal may be, but not limited to, a smart phone or a portable notebook computer, and the digital asset management server may be, but not limited to, a cloud server, and the like, and the cloud server further includes a corresponding database, where video/picture data of different types and contents are stored. The digital asset management server can periodically send connection request instructions to a plurality of mobile terminals respectively, and after the mobile terminals receive and confirm the connection request instructions, corresponding feedback information is returned to the digital asset management server, and at the moment, the mobile terminals and the digital asset management server successfully construct corresponding connection relations. If the mobile terminal is in a dormant or power-off state, the mobile terminal does not return any feedback message in the process of periodically receiving the connection request instruction, and the digital asset management server cannot receive the feedback message for a long time; if the mobile terminal is in a starting-up state, the mobile terminal returns corresponding feedback information in time once receiving the connection request instruction.
And determining whether the mobile terminal is in a normal working state or not by determining the waiting time length corresponding to the feedback message of each mobile terminal about the connection request instruction received by the digital asset management server and performing corresponding threshold comparison. In actual operation, when the waiting time length is greater than or equal to a preset time length threshold, the mobile terminal is indicated to be in a dormant or power-off state currently, the mobile terminal is not required to acquire video/pictures, and at the moment, the mobile terminal stops sending a connection request instruction to the mobile terminal; when the waiting time length is smaller than the preset time length threshold, the mobile terminal is in a starting state at present, the mobile terminal is in need of acquiring video/pictures, and at the moment, the connection request instruction is continuously and periodically sent until the digital asset management server acquires the feedback information. Through the process, the continuous transmission of the connection request instruction without restriction to the mobile terminal in the dormant or power-off state by the digital asset management server can be effectively avoided, so that the workload of the digital asset management server is greatly reduced. And then the mobile terminal packages the GPS position information and the data type demand information of the mobile terminal to form a feedback message, and directly returns the feedback message to the digital asset management server so as to facilitate the subsequent communication interaction between the mobile terminal and the digital asset management server.
Preferably, in the step S2, according to the current location information of each mobile terminal, the corresponding mobile terminal is determined as a mobile terminal capable of sharing data and a mobile terminal incapable of sharing data; and then according to the data demand information of the mobile terminal capable of sharing the data, determining the multimedia data which is actually required to be acquired comprises the following specific steps:
step S201, determining the linear distance between the mobile terminal and the digital asset management server according to the GPS position information of the mobile terminal and the GPS positioning information of the digital asset management server;
step S202, determining the actual signal strength of the wireless signal received by the mobile terminal from the digital asset management server according to the linear distance; comparing the actual signal strength with a preset signal strength threshold; if the actual signal strength is greater than or equal to a preset signal strength threshold, determining the corresponding mobile terminal as a mobile terminal capable of sharing data; if the actual signal strength is smaller than a preset signal strength threshold, determining the corresponding mobile terminal as a mobile terminal which cannot share data;
step S203, analyzing the data demand information from the mobile terminal capable of sharing data, thereby determining the multimedia data which the mobile terminal capable of sharing data actually needs to acquire; wherein the multimedia data includes video data or picture data.
The beneficial effects of the technical scheme are as follows: because the digital asset management server communicates with the mobile terminal through the wireless signal, the signal strength of the wireless signal decays as the propagation distance becomes longer, and when the linear distance between the mobile terminal and the digital asset management server is too large, the mobile terminal cannot receive the wireless signal with sufficient strength, i.e. cannot normally and continuously communicate with the digital asset management server. The signal strength attenuation amplitude of the wireless signal and the propagation distance of the wireless signal are usually in an exponential attenuation relationship, so that the actual signal strength of the wireless signal received by the mobile terminal from the digital asset management server can be determined according to the linear distance between the mobile terminal and the digital asset server, and the process is a conventional wireless signal strength calculation manner in the art, and is not described in detail herein.
When the actual signal strength corresponding to the mobile terminal is greater than or equal to a preset signal strength threshold, indicating that the actual signal strength is enough to maintain normal continuous communication between the mobile terminal and the digital asset management server, wherein the mobile terminal belongs to a mobile terminal capable of sharing data; when the actual signal strength corresponding to the mobile terminal is smaller than the preset signal strength threshold, the actual signal strength is enough to maintain the normal continuous communication between the mobile terminal and the digital asset management server, and the mobile terminal belongs to the mobile terminal which cannot share data. Then, only the data demand information from the mobile terminal which can share the data is analyzed, so that the workload of analyzing the data demand information can be reduced.
Preferably, in the step S3, corresponding multimedia data is found from the digital asset management server according to the multimedia data acquired in actual need; the mobile terminal for sequentially performing format conversion processing and packaging processing on the found multimedia data and then transmitting the multimedia data to corresponding sharable data specifically comprises:
step S301, extracting at least one frame of image from the multimedia data which is actually needed to be acquired; performing identification processing on the at least one frame of image so as to obtain actual image contour feature information corresponding to the at least one frame of image;
step S302, finding out multimedia data with the highest similarity with the actual image contour feature information from a database of a digital asset management server;
step S303, converting the found multimedia data into a data format with a read-only form, and then performing fidelity compression packaging processing to obtain a corresponding data packet; and transmits the data packet to the corresponding mobile terminal which can share the data.
The beneficial effects of the technical scheme are as follows: and obtaining video/picture data which are actually required to be obtained by the mobile terminal from the data demand information, wherein the video/picture data which are actually required to be obtained exist in the form of images. The video/picture data to be obtained in practice generally includes a plurality of frames of images, and at least one frame of image is extracted therefrom, and an image contour recognition process is performed on the at least one frame of image, so as to obtain corresponding actual image contour feature information, where the image contour recognition process is a conventional image processing manner in the art, and will not be described in detail herein. Then, the video/picture data having the highest similarity with the actual image profile feature information is found from the database of the digital asset management server, wherein the similarity of the actual image profile feature information and the video/picture data existing in the database of the digital asset management server can be determined by determining the image profile feature quantization difference (such as arithmetic difference) between the two image profile feature information, and when the image profile feature quantization difference is smaller, the similarity of the two image profile feature information and the video/picture data is higher. And finally, converting the found video/picture into a data format in a non-editable read-only form, and then performing fidelity compression packaging processing to obtain a corresponding data packet, so that the data packet can be ensured to be rapidly and safely transmitted to a corresponding mobile terminal capable of sharing data, and the data security of the data packet is improved.
Preferably, in the step S303, after converting the found multimedia data into a data format having a read-only format, performing a fidelity compressing and packaging process to obtain a corresponding data packet specifically includes:
if the multimedia data is video data, converting the found video data into a data format with a read-only form, and then performing fidelity compression packaging processing to obtain a corresponding data packet, wherein the specific process is as follows:
step S3031, the video data is formed by playing multi-frame picture data according to time sequence, and screening the repeated picture data existing in the video data by using the following formula (1),
in the above formula (1), lambda a,a+b A repetition flag value representing a repetition flag between a-th frame picture data and a+b-th frame picture data in the video data; d (D) a (i, j) representing a pixel value of an ith row and a jth column of pixel points of an a-th frame picture data in the video data; d (D) a+b (i, j) representing a pixel value of a j-th row of the i-th column of the a+b-th frame picture data in the video data; m represents the number of pixels included in each line of each frame of picture data in the video data; n represents the number of pixels included in each column of each frame of picture data in the video data; delta [ ]The function value of the zero function is 1 when the value in the bracket is 0, and the function value of the zero function is 0 when the value in the bracket is not 0; r represents the total number of videos contained in the video data;
when lambda is a,a+b =1, indicating that the a-th frame picture data and the a+b-th frame picture data in the video data are repeated;
when lambda is a,a+b =0, indicating that the a-frame picture data and the a+b-frame picture data in the video data are not duplicated;

The multi-mobile terminal data sharing system based on digital asset management comprises a digital asset management server, a plurality of mobile terminals, a mobile terminal identification module, a digital asset inquiry module and a digital asset processing module; wherein,
The digital asset management server is used for respectively sending a connection request instruction to a plurality of mobile terminals and obtaining feedback information of each mobile terminal about the connection request instruction; analyzing the feedback information to determine the current position information and the current data demand information of each mobile terminal;

the digital asset inquiry module is used for searching corresponding multimedia data from the digital asset management server according to the multimedia data acquired by the actual requirement;
the digital asset processing module is used for sequentially carrying out format conversion processing and packaging processing on the searched multimedia data and then transmitting the multimedia data to the corresponding mobile terminal capable of sharing the data.
The beneficial effects of the technical scheme are as follows: the multi-mobile terminal data sharing system based on digital asset management can ensure that a digital asset management server can simultaneously perform data sharing with a plurality of mobile terminals, and can also perform data query by taking the image content of video and/or pictures as a search basis, so that the searchable range of the video and/or pictures can be enlarged, and the searching efficiency and accuracy of the video and/or pictures can be improved.
Preferably, the digital asset management server is configured to send connection request instructions to a plurality of mobile terminals, respectively, and obtain feedback messages of each mobile terminal about the connection request instructions; and analyzing the feedback message to determine the current location information and data requirement information of each mobile terminal, wherein the method specifically comprises the following steps:
the digital asset management server periodically sends a connection request instruction to a plurality of mobile terminals through the digital asset management server, and determines the waiting time length corresponding to the feedback information of each mobile terminal about the connection request instruction; the waiting time length refers to the time length from the time when the digital asset management server sends a connection request instruction to the mobile terminal until the digital asset management server receives a corresponding feedback message;
comparing the waiting time length with a preset time length threshold; if the waiting time length is greater than or equal to a preset time length threshold, stopping sending a connection request instruction to the corresponding mobile terminal; if the waiting time length is smaller than the preset time length threshold, continuing to periodically send a connection request instruction to the corresponding mobile terminal until the feedback message is obtained;
And then analyzing the feedback information so as to obtain GPS position information and data type demand information of the corresponding mobile terminal.
The beneficial effects of the technical scheme are as follows: the plurality of mobile terminals can be connected with the digital asset management server through a wireless network; the mobile terminal may be, but not limited to, a smart phone or a portable notebook computer, and the digital asset management server may be, but not limited to, a cloud server, and the like, and the cloud server further includes a corresponding database, where video/picture data of different types and contents are stored. The digital asset management server can periodically send connection request instructions to a plurality of mobile terminals respectively, and after the mobile terminals receive and confirm the connection request instructions, corresponding feedback information is returned to the digital asset management server, and at the moment, the mobile terminals and the digital asset management server successfully construct corresponding connection relations. If the mobile terminal is in a dormant or power-off state, the mobile terminal does not return any feedback message in the process of periodically receiving the connection request instruction, and the digital asset management server cannot receive the feedback message for a long time; if the mobile terminal is in a starting-up state, the mobile terminal returns corresponding feedback information in time once receiving the connection request instruction.
And determining whether the mobile terminal is in a normal working state or not by determining the waiting time length corresponding to the feedback message of each mobile terminal about the connection request instruction received by the digital asset management server and performing corresponding threshold comparison. In actual operation, when the waiting time length is greater than or equal to a preset time length threshold, the mobile terminal is indicated to be in a dormant or power-off state currently, the mobile terminal is not required to acquire video/pictures, and at the moment, the mobile terminal stops sending a connection request instruction to the mobile terminal; when the waiting time length is smaller than the preset time length threshold, the mobile terminal is in a starting state at present, the mobile terminal is in need of acquiring video/pictures, and at the moment, the connection request instruction is continuously and periodically sent until the digital asset management server acquires the feedback information. Through the process, the continuous transmission of the connection request instruction without restriction to the mobile terminal in the dormant or power-off state by the digital asset management server can be effectively avoided, so that the workload of the digital asset management server is greatly reduced. And then the mobile terminal packages the GPS position information and the data type demand information of the mobile terminal to form a feedback message, and directly returns the feedback message to the digital asset management server so as to facilitate the subsequent communication interaction between the mobile terminal and the digital asset management server.
Preferably, the mobile terminal identification module is configured to determine, according to the current location information of each mobile terminal, the corresponding mobile terminal as a mobile terminal capable of sharing data and a mobile terminal incapable of sharing data; and then according to the data demand information of the mobile terminal capable of sharing the data, determining the multimedia data which is actually required to be acquired comprises the following specific steps:

The signal strength attenuation amplitude of the wireless signal and the propagation distance of the wireless signal are usually in an exponential attenuation relationship, so that the actual signal strength of the wireless signal received by the mobile terminal from the digital asset management server can be determined according to the linear distance between the mobile terminal and the digital asset server, and the process is a conventional wireless signal strength calculation manner in the art, and is not described in detail herein.
When the actual signal strength corresponding to the mobile terminal is greater than or equal to a preset signal strength threshold, indicating that the actual signal strength is enough to maintain normal continuous communication between the mobile terminal and the digital asset management server, wherein the mobile terminal belongs to a mobile terminal capable of sharing data; when the actual signal strength corresponding to the mobile terminal is smaller than the preset signal strength threshold, the actual signal strength is enough to maintain the normal continuous communication between the mobile terminal and the digital asset management server, and the mobile terminal belongs to the mobile terminal which cannot share data. Then, only the data demand information from the mobile terminal which can share the data is analyzed, so that the workload of analyzing the data demand information can be reduced.

The video/picture data to be obtained in practice generally includes a plurality of frames of images, and at least one frame of image is extracted therefrom, and an image contour recognition process is performed on the at least one frame of image, so as to obtain corresponding actual image contour feature information, where the image contour recognition process is a conventional image processing manner in the art, and will not be described in detail herein. Then, the video/picture data having the highest similarity with the actual image profile feature information is found from the database of the digital asset management server, wherein the similarity of the actual image profile feature information and the video/picture data existing in the database of the digital asset management server can be determined by determining the image profile feature quantization difference (such as arithmetic difference) between the two image profile feature information, and when the image profile feature quantization difference is smaller, the similarity of the two image profile feature information and the video/picture data is higher. And finally, converting the found video/picture into a data format in a non-editable read-only form, and then performing fidelity compression packaging processing to obtain a corresponding data packet, so that the data packet can be ensured to be rapidly and safely transmitted to a corresponding mobile terminal capable of sharing data, and the data security of the data packet is improved.
