[0021] The following will refer to Figure 1 The flowchart of the wireless transmission method based on the AES audio processing technology is shown, and a wireless transmission method based on the AES audio processing technology is introduced.

[0022] The wireless transmission method based on AES audio processing technology may include the following steps:

[0023] S100, obtaining each preset environmental factor vector to obtain a preset environmental factor vector list A=(A1, A2, ..., A i , …, A n ), i=1, 2,...,n; among them, A i is the i-th preset environmental factor vector, n is the number of preset environmental factor vectors; A i =(A i，1 , A i，2 , …, A i，j , …, A i，m )、j=,2,…,m;A i，j is the value corresponding to the j-th type of environmental factor corresponding to the i-th preset environmental factor vector, and m is the number of types of preset environmental factors.

[0024] In this embodiment, the target plant can be any plant; it is understandable that for the target plant, the internal environmental factors include temperature, humidity, dust concentration, etc.; several groups of preset environmental factor vectors can be set in an exhaustive manner; for example: when the temperature is 28°C, the humidity is 50%, and the dust concentration is 100mg / m 3 Under the environmental factor, the corresponding preset environmental factor vector is (28, 0.5, 100); theoretically, it is possible to set a preset environmental factor vector with continuous values ​​corresponding to several environmental factors to obtain A.

[0025] S200, according to A, determine the wireless signal attenuation rate from the transmitting end to the receiving end of the target plant in the environment corresponding to each preset environmental factor vector, so as to obtain a first wireless signal attenuation rate list α=(α1, α2, …, α i , …, α n ); where α i For A i In the corresponding environment, the wireless signal attenuation rate from the transmitter to the receiver of the target factory building.

[0026] In this embodiment, the positions of the transmitting end and the receiving end of the audio wireless signal are fixed, and the environment corresponding to each preset environmental vector factor can be set in the target factory, and then the signal attenuation rate corresponding to the transmission of the wireless signal from the transmitting end to the receiving end is tested; it should be noted that those skilled in the art can use the existing wireless signal attenuation rate testing method according to actual needs to determine the wireless signal attenuation rate from the transmitting end to the receiving end of the target factory in the environment corresponding to each preset environmental factor vector, which will not be elaborated here; during the above test process, the target factory is always in an empty state, that is, no objects are placed in the target factory, and the attenuation of the wireless signal is not affected by the placed objects.

[0027] S300, dividing the target plant into a number of continuous three-dimensional grids to obtain a three-dimensional grid list B corresponding to the target plant = (B1, B2, ..., B p , …, B q ), p = 1, 2, …, q; where B p is the pth three-dimensional grid obtained by dividing the target factory building, and q is the number of three-dimensional grids obtained by dividing the target factory building.

[0028] In this embodiment, the size of the three-dimensional grid can be set according to actual needs, and the height of the three-dimensional grid can be the height of the target factory building; it can be understood that the three-dimensional grid is a virtual grid for the convenience of subsequent calculations.

[0029] S400, placing objects of y different placement forms in the target factory in sequence, and obtaining the actual environmental factor vector, object placement form vector and wireless signal attenuation rate corresponding to each placement form, so as to obtain an actual environmental factor vector list C = (C1, C2, ..., C x , …, C y ), object placement vector list D = (D1, D2, ..., D x , …, D y ) and the second wireless signal attenuation rate list β=(β1, β2, …, β x , …, β y ), x=1, 2, …, y; where C x , D x and β x They are the actual environmental factor vector, object placement vector, and wireless signal attenuation rate corresponding to the x-th placement form; D x =(D x，1 , D x，2 , …, D x，p , …, D x，q );D x，p It is the proportion of the p-th three-dimensional grid occupied by the object when the object is placed in the x-th arrangement form.

[0030] In this embodiment, y kinds of objects in different placement forms can be placed in the target factory, and the placement forms include the placement position of the object and the size of the object, etc.; it should be noted that the y kinds of objects in different placement forms cover the placement forms of objects frequently used in the target factory; after placing objects in one form, the wireless signal attenuation rate from the transmitting end to the receiving end can be tested under the objects in this placement form, and at the same time, the corresponding environmental factor vector and object placement form vector under the objects in this placement form can also be obtained.

[0031] It can be understood that after placing objects in a certain arrangement in the target factory, the objects will fill part of the three-dimensional grid. Due to the different heights and sizes of the objects, the filled three-dimensional grid may be filled or not. The volume of the objects filled in each three-dimensional grid can be obtained. Combined with the total volume of each three-dimensional grid, the proportion of each three-dimensional grid occupied by the objects can be obtained. The materials corresponding to objects in different arrangement forms are the same.

[0032] S500, determining the current wireless signal attenuation rate α of the wireless signal from the transmitting end to the receiving end of the target plant according to A, α, C, β, D, the current environmental factor vector in the target plant and the current object placement shape vector now .

[0033] Further, step S500 may include the following steps:

[0034] S510, get C x The similarity between each preset environmental factor vector in A to obtain C x The corresponding first similarity list TC x =(TC x，1 , TC x，2 ,…,TC x，i ,…,TC x，n ); where TC x，i C x With A i The similarity in the middle.

[0035] S520, according to TC x , determine C x The corresponding first target similarity MC x =MAX(TC x ); where MAX() is the preset maximum value function.

[0036] In this embodiment, MC x The corresponding environmental factor vector and C x Most similar, indicating MC x The corresponding environmental factor vector environment and C x The corresponding environment is most similar; it can be understood that if the step size between the values ​​corresponding to the environmental factors in the preset environmental factor vector is small, MC x can be close to 1, that is, almost the same preset environmental factor vector can be determined.

[0037] S530, determine MC according to α x The wireless signal attenuation rate SC of the corresponding preset environmental factor vector x .

[0038] In this way, the attenuation rate of the wireless signal caused by environmental factors alone can be determined without considering the influence of objects.

[0039] S540, according to β x and SC x , determine the wireless signal attenuation rate γ from the transmitter to the receiver of the target plant affected by the x-th placement of objects x =β x -SC x , and then obtain the third wireless signal attenuation rate list γ=(γ1,γ2,…,γ x , …, γ y ).

[0040] In this embodiment, it can be understood that the attenuation of wireless signals is affected by objects and the environment. After determining the wireless signal attenuation rate corresponding to the influence of the environment, the wireless signal attenuation rate from the transmitting end to the receiving end of the target factory affected by the objects placed in the xth form can be determined by taking a difference.

[0041] It should be noted that the above steps only need to be executed once for the target plant, and the obtained results can be saved in a preset location and can be used directly in subsequent processes.

[0042] S550, determine α according to γ, α, D, the current environmental factor vector in the target plant and the current object placement vector. now .

[0043] Further, step S550 may include the following steps:

[0044] S551, obtain the current environmental factor vector A in the target factory now And the current object placement vector D now .

[0045] In this embodiment, it is understandable that the environment and placement of objects in the target plant may change, so it is necessary to obtain the current environmental factor vector A in the target plant. now And the current object placement vector D now , in order to determine the transmission power of the transmitter based on the current actual situation.

[0046] S552, Get A now The similarity between each preset environmental factor vector in A to obtain A now The corresponding second similarity list TA now =(TA now，1 ,TA now，2 ,…,TA now，i ,…,TA now，n ); where TA now，i A now With A i The similarity between .

[0047] In this embodiment, it should be noted that those skilled in the art can use existing vector similarity determination methods according to actual needs to obtain A now The similarity between each preset environmental factor vector in A is not described here.

[0048] S553, according to TA now , determine A now The corresponding second target similarity MA now =MAX(TA now).

[0049] S554, according to α, determine MA now The wireless signal attenuation rate SA of the corresponding preset environmental factor vector now .

[0050] In this embodiment, through the above steps, the wireless signal attenuation rate corresponding to the current environment in the target factory building can be determined.

[0051] S555, Get D now The similarity between the placement shape vector of each object in D is obtained now The corresponding third similarity list TD now =(TD now，1 , TD now，2 ,…,TD now，x ,…,TD now，y ); where TD now，x D now With D x The similarity between .

[0052] Furthermore, TD now，x This can be determined by the following steps:

[0053] S51, get D now =(D now，1 , D now，2 , …, D now，p , …, D now，q ); where D now，p To place D now The corresponding object is the proportion of the p-th three-dimensional grid occupied by the object.

[0054] S52, according to D now and D x , determine D now and D x The difference in the occupancy ratio of each object in , to obtain the difference list ΔD now =(ΔD now，1 , ΔD now，2 ,…,ΔD now，p ,…,ΔD now，q ); where ΔD now，p D now，p With D x，p The difference between .

[0055] S53, according to ΔD now , determine TD now，x =∑ q p=1 (ε p ×ΔD now，p ); where εp is the weight corresponding to the p-th three-dimensional grid; if the p-th three-dimensional grid is located at the first preset position, then ε p is the first preset weight; if the pth three-dimensional grid is located at the second preset position, then ε p is the second preset weight; the first preset position is located in the peripheral area of ​​the target plant, and the second preset position is located in the middle area of ​​the target plant; the first preset weight is less than the second preset weight; ∑ q p=1 ε p =1.

[0056] In this embodiment, it can be understood that the positions of the transmitting end and the receiving end of the wireless signal in the target factory building are fixed and located at both ends of the target factory building; during the transmission of the wireless signal, objects are located in different areas, and the degree of influence on the attenuation of the wireless signal is different; the area with a greater impact on the attenuation of the wireless signal is the area near the transmission path, that is, the middle area of ​​the target factory building, while the surrounding area of ​​the target factory building has less impact on the attenuation of the wireless signal. Therefore, the weight of the three-dimensional grid located in the middle area is set larger, so that the determined similarity is more in line with the actual situation, thereby improving the accuracy of the target power determination.

[0057] S556, according to TD now , determine D now The corresponding third target similarity MD now =MAX(TD now ).

[0058] S557, according to γ, determine MD now D now The wireless signal attenuation rate SD affected by the corresponding object now .

[0059] S558, according to SA now and SD now , determine α now =SA now +SD now .

[0060] In this embodiment, through the above steps, the wireless signal attenuation rate that matches the current environmental factors and the placement of objects can be determined, and it will change in real time.

[0061] S600, according to α now and the minimum signal reception strength at the receiving end to determine the target transmission power at the transmitting end.

[0062] Further, step S600 may include the following steps:

[0063] S610, obtaining the minimum signal receiving strength E of the receiving endmin .

[0064] In this embodiment, the minimum signal strength required to ensure smooth and stable transmission of the audio signal can be obtained through experiments, which will not be described in detail here.

[0065] S620, according to E min and α now , determine the minimum signal transmission strength F corresponding to the transmitter min =E min / α now .

[0066] In this embodiment, it can be understood that during the transmission of the wireless signal from the transmitting end to the receiving end, attenuation will occur. now and E min Afterwards, the wireless signal strength corresponding to the transmitting end can be determined.

[0067] S630, according to F min , determine the target transmission power of the transmitter W = μ × W min ; Among them, W min F min Corresponding transmit power; μ is the preset transmit power weight, μ>1.

[0068] In this embodiment, the transmitting end transmits a signal strength of F min The transmission power required for the wireless signal can be determined by experiments or according to relevant equipment parameters; μ is set to increase redundancy and ensure that the audio signal remains stable and smooth in the wireless transmission project; for example: μ=1.2.

[0069] S700, adjusting the transmission power of the transmitting end to the target transmission power, and transmitting the audio after AES encryption.

[0070] In this embodiment, it should be noted that those skilled in the art can use the existing AES encryption algorithm to encrypt the audio to be transmitted according to actual needs, which will not be elaborated here.

[0071] The wireless transmission method based on AES audio processing technology of this embodiment determines the wireless signal attenuation rate of the wireless signal from the transmitting end to the receiving end of the target factory building without placing any objects; divides the target factory building into a number of continuous three-dimensional grids, and places a number of objects with different placement forms in the target factory building, obtains the wireless signal attenuation rate corresponding to each object with each placement form, and combines the wireless signal attenuation rate corresponding to each preset environmental factor when no objects are placed to determine the wireless signal attenuation rate affected by objects with different placement forms; determines the optimal target transmission power of the transmitting end under the current environmental factors and object placement forms according to the current environmental factor vector and the current object placement form vector in the target factory building; thereby, on the premise of ensuring the stability of wireless transmission of the audio signal, the wireless signal transmission power of the transmitting end is adaptively determined to avoid the transmission power of the transmitting end being in the state of maximum transmission power all the time, thereby delaying the aging of the wireless signal transmitting equipment and increasing the service life of the wireless signal transmitting equipment.
