Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. 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.
In the related art, for a wide and narrow band ad hoc network terminal, if the wide and narrow band communication modules are always turned on, the efficiency of information transmission can be improved because the wide band communication module and the narrow band communication module work simultaneously. However, due to the different capacities of the collected multi-source information and the different transmission efficiency of the broadband communication module and the narrowband communication module, the problem that the information can not be quickly transmitted and fused by utilizing the narrowband communication module in time still exists.
Referring to fig. 1, a flowchart of a multi-source information fusion method based on broadband and narrowband communication is shown.
The multisource information fusion method based on wide and narrow band communication is applied to a wide and narrow band ad hoc network terminal, and the wide and narrow band ad hoc network terminal comprises a narrow band channel, a wide band channel and fusion channels respectively connected with the narrow band channel and the wide band channel. As shown in fig. 1, the multi-source information fusion method based on wide-narrow-band communication specifically includes the following steps:
step S101, performing information analysis on the obtained multi-source information to obtain a first information sequence containing at least one first information and a second information sequence containing at least one second information, where the first information sequence has a first association relationship with the wideband channel, and the second information sequence has a second association relationship with the narrowband channel.
In the step, multi-source information is acquired, wherein the multi-source information comprises at least two pieces of information with different capacities; respectively adding different white noises into at least two pieces of information with different capacities to expand the capacity until the capacities of the information are consistent, wherein the types of the different white noises are consistent with the types of the information with different capacities; judging whether the capacity of each white noise is larger than a preset capacity threshold value or not; if the capacity of a certain white noise is larger than a preset data quantity threshold value, defining information corresponding to the certain white noise as second information, and incorporating the second information into a second information sequence; and if the capacity of a certain white noise is not greater than the preset data quantity threshold value, defining the information corresponding to the certain white noise as first information, and incorporating the first information into a first information sequence.
For example, the acquired multi-source information includes audio information and video information to which white noise is added, respectively. Judging whether the capacity of each white noise is larger than a preset capacity threshold value or not; if the capacity of the white noise added to the audio information is greater than the preset data amount threshold, the capacity of the audio information is smaller, and the audio information is regarded as a second information sequence and is transmitted through a narrow-band channel with transmission efficiency smaller than that of a wide-band channel. If the capacity of the white noise added to the video information is not greater than the preset data amount threshold, the capacity of the video information is smaller, and the video information is regarded as a first information sequence and is transmitted through a broadband channel with transmission efficiency greater than that of a narrowband channel.
It should be noted that, in this embodiment, different white noises are added, and the capacity of the white noises is analyzed, and the purposes are as follows: 1. compared with the acquired multi-source information, the added white noise is less, and the capacity of the white noise can be conveniently analyzed; 2. in the process of analyzing the capacity of multi-source information, information omission or damage may be caused.
Step S102, determining whether the difference between the number of information in the second information sequence and the number of information in the first information sequence is greater than a preset threshold.
In practical application, if the information in the wideband channel and the narrowband channel is not greater than a preset threshold value, directly inputting the first information sequence and the second information sequence into the wideband channel and the narrowband channel, and fusing the information in the wideband channel and the narrowband channel for the first time through a fusion channel to obtain at least one first target information; and performing second fusion on at least one first target information to obtain a final multi-source information fusion result.
Step S103, if the first information is larger than the preset threshold value, at least one piece of first information in the first information sequence or at least one piece of second information in the second information sequence is partially intercepted based on a preset interception rule, so as to obtain a third information sequence containing partial first information or second information, wherein the third information sequence has a third association relation with the broadband channel or the narrowband channel.
In the step, each piece of second information in the second information sequence is in one-to-one correspondence with each piece of first information in the first information sequence; and cutting at least one piece of second information which is not corresponding in the second information sequence or at least one piece of first information which is not corresponding in the first information sequence, and obtaining a third information sequence containing part of the first information or the second information.
For example, the number of second information in the second information sequence is 10, the number of first information in the first information sequence is 6, and after each second information in the second information sequence is in one-to-one correspondence with each first information in the first information sequence, four second information in the second information sequence are corresponding. Thus, four second messages are truncated as third messages and are summarized as third message sequences.
Step S104, respectively inputting the intercepted first information sequence and second information sequence into the broadband channel and the narrowband channel based on a target transmission rule in a preset first time period, and fusing information in the broadband channel and the narrowband channel for the first time through the fusion channel to obtain at least one first target information, wherein the target transmission rule is as follows: and aligning and transmitting a certain first information in the first information sequence and a certain second information in the second information sequence based on the same time node.
In this step, the first time period includes at least one first time sub-period.
Specifically, judging whether the information quantity of information transmission in a wideband channel and a narrowband channel is the same in the same first time sub-period; if the first information and the second information are different, redundant first information or second information is classified as first information or second information transmitted in the next first time sub-period based on the time sequence of transmission; aligning the same amount of first information and second information in the same first time sub-period for first fusion to obtain at least one first target information; if the first information and the second information are the same, the same number of first information and the same number of second information in the same first time sub-period are directly aligned for first fusion, and at least one first target information is obtained.
In practical application, if the number of information transmitted by the wideband channel is 1 and the number of information transmitted by the narrowband channel is 2 in the same first time sub-period, the second information with a later time is classified as the information transmitted by the next first time sub-period based on the time sequence of transmission. In this fusion rule, there may be a single second information that is not fused in the last time sub-period, so before fusing the third information in the third information sequence with a certain first target information for the second time via the fusion channel, and fusing the second target information obtained after the second time and all the first target information except for the certain first target information for the third time, the method further includes: and fusing the third information in the third information sequence with the unaligned first information or second information transmitted in the last first time sub-period through a fusion channel to obtain at least one first target information.
Step S105, inputting the third information sequence into the wideband channel or the narrowband channel based on a target transmission rule in a preset second time period, performing second fusion on third information in the third information sequence and a certain first target information through the fusion channel, and performing third fusion on the second target information obtained after the second fusion and all first target information except for the certain first target information, thereby obtaining a final multi-source information fusion result.
In summary, the method divides the multisource information into the first information and the second information, and transmits the first information and the second information through the related wideband channel and narrowband channel, so that the transmission efficiency of the wideband channel and the narrowband channel can be adapted, further, ordered rapid transmission is achieved, when the difference between the information quantity in the second information sequence and the information quantity in the first information sequence is larger than a preset threshold, the third information sequence is partially intercepted based on a preset interception rule, the third information sequence containing part of the first information or the third information sequence containing part of the second information is obtained, the intercepted first information sequence and second information sequence are respectively input into the wideband channel and the narrowband channel in a preset first time period based on a target transmission rule, the information in the wideband channel and the narrowband channel is fused for the first time through the fusion channel to obtain at least one first target information, the third information sequence is input into the wideband channel or the narrowband channel based on a target transmission rule in a preset second time period, the first target in the third information sequence and the first target information in the first information sequence are fused with the second information in the fusion channel for the second time period, and the first target in the first time can be removed, and all the target information in the first time can be fused, and the second target can be fused for the first target and the second target can be obtained.
