Description

Technical Field

[0001] This application relates to the technical field of radio frequency signals, and particularly to a method, system, and storage medium for amplifying radio frequency signals. Background Art

[0002] As the core carrier of wireless communication, radio frequency signals are not only the physical basis for realizing technologies such as mobile communication, satellite navigation, radar detection, and the Internet of Things, but also the key medium for achieving high-speed, long-distance, and large-capacity data transmission in the information age. From daily wireless and Bluetooth connections to aerospace communications, radio frequency signals support the development of social digitalization and intelligence and are an indispensable core element in the field of wireless communication technology. However, radio frequency signals will attenuate and gradually weaken due to factors such as free space path loss and obstacle occlusion, resulting in weak signals when the radio frequency signals reach the receiving end and cannot be effectively used. Therefore, it is necessary to amplify the radio frequency signals before sending them to the receiving end.

[0003] At the current stage, when amplifying radio frequency signals before sending them to the receiving end, generally, the radio frequency signals are first amplified, and then a splitter is used to divide the amplified radio frequency signals into several required paths according to the required ratio, and then each path is transmitted, so that the radio frequency signals reach each receiving end, and the signals when reaching the receiving end can be effectively used. That is, the existing method uniformly amplifies the radio frequency signals before splitting the radio frequency signals. Although it can enable the receiving end to obtain effective radio frequency signals, it is necessary to obtain the radio frequency signal strength required by all receiving ends before the method of radio frequency signals can be carried out, otherwise it is impossible to determine how much amplification work needs to be done on the radio frequency signals. However, different receiving ends do not necessarily synchronize when determining the required radio frequency signals, resulting in a certain lag in the radio frequency signal amplification work. Summary of the Invention

[0004] To alleviate the lag in the radio frequency signal amplification work, embodiments of this application provide a method, system, and storage medium for amplifying radio frequency signals.

[0005] In a first aspect, a method for amplifying radio frequency signals is provided, and the method includes:

[0009] Amplify the corresponding sub - radio frequency signals according to the signal attenuation information to obtain amplified sub - radio frequency signals;

[0010] Among them, the sub - radio frequency signals include a first sub - radio frequency signal and a second sub - radio frequency signal, and the splitting of the initial radio frequency signal to obtain a plurality of sub - radio frequency signals includes:

[0019] In some embodiments, the substituting the transmission environment into a preset model to obtain the signal attenuation information experienced by the sub - radio frequency signals corresponding to each receiving end when reaching the receiving end includes:

[0021] Sort all receivers in descending order according to the demand level to obtain a receiver group. Divide the transmission environment corresponding to the first receiver in the receiver group into several sub-transmission information groups according to attributes. Among them, each sub-transmission information group corresponds to a uniquely determined attribute, and the sub-transmission environments in each sub-transmission information group are stored in order of distance from the receiver from far to near in the corresponding attribute;

[0022] Form a vertical vector with all sub-transmission information groups according to a preset attribute sequence. Substitute the vertical vector as input information into the input end of the preset model, and use the output information output from the output end of the preset model as the signal attenuation information experienced by the sub-radio frequency signal corresponding to the receiver when reaching the receiver;

[0023] When substituting the vertical vector as input information into the input end of the preset model, determine whether the transmission environments corresponding to all receivers in the receiver group are divided into several sub-transmission information groups according to attributes. If so, generate an end signal to obtain the signal attenuation information experienced by all receivers;

[0024] If not, continue to divide the transmission environment corresponding to the next receiver in the receiver group into several sub-transmission information groups according to attributes.

[0025] In some embodiments, the preset model is a BP neural network, and the demand information further includes the demand signal strength corresponding to each receiver. After obtaining the amplified sub-radio frequency signal by amplifying the corresponding sub-radio frequency signal according to the signal attenuation information, it further includes:

If it meets, generate a reception success signal;

[0027] If it does not meet, use the signal difference to adjust the parameters of the last layer of the preset model to realize the online adjustment of the preset model, obtain a new preset model, and update the preset model to the new preset model.

[0036] The processing module is configured to determine the transmission environment for the sub - RF signal corresponding to each receiver to reach the receiver based on the demand information, and substitute the transmission environment into a preset model to obtain the signal attenuation information experienced by the sub - RF signal corresponding to each receiver to reach the receiver;

[0037] The amplification module is configured to amplify the corresponding sub - RF signal according to the signal attenuation information to obtain an amplified sub - RF signal.

[0038] In a third aspect, a computer - readable storage medium is provided, on which a computer program capable of running on a processor is stored. When the computer program is executed by the processor, it implements an amplification method for RF signals as described in the first aspect.

[0039] By adopting the above method, the present application first obtains an initial radio frequency signal, splits the initial radio frequency signal to obtain a plurality of sub-radio frequency signals. Then, demand information is received, where the demand information includes at least one receiving end, and each receiving end corresponds to a sub-radio frequency signal. Based on the demand information, the transmission environment for each sub-radio frequency signal corresponding to each receiving end to reach the receiving end is determined, and the transmission environment is substituted into a preset model to obtain the signal attenuation information experienced by each sub-radio frequency signal corresponding to each receiving end when reaching the receiving end. Finally, the corresponding sub-radio frequency signal is amplified according to the signal attenuation information to obtain an amplified sub-radio frequency signal. In this way, the initial radio frequency signal is first split, and then the subsequent information for determining the signal amplification required for each split is determined in real time according to the demand, and finally the corresponding amplification is performed according to the information requiring amplification, which can alleviate the lag in the radio frequency signal amplification work.

[0045] To more clearly understand the purpose, technical solution, and advantages of the present application, the present application will be described and illustrated below with reference to the accompanying drawings and embodiments. However, those of ordinary skill in the art should understand that the present application can be implemented without these details. For those of ordinary skill in the art, it is obvious that various changes can be made to the disclosed embodiments of the present application, and the general principles defined in the present application can be applied to other embodiments and application scenarios without departing from the principles and scope of the present application. Therefore, the present application is not limited to the illustrated embodiments, but conforms to the broadest scope consistent with the scope claimed in the present application.

[0046] The embodiments of the present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0047] Figure 1 It is a block diagram of a method for amplifying a radio frequency signal provided by an embodiment of the present application. As Figure 1 shown, a method for amplifying a radio frequency signal includes the following steps:

[0048] Step S100, obtain an initial radio frequency signal, and split the initial radio frequency signal to obtain a plurality of sub-radio frequency signals.

[0049] The embodiment of the present application is described from the perspective of the processing end. The above-mentioned initial radio frequency signal refers to a radio frequency signal generated by a radio frequency signal source or other devices, that is, an unprocessed radio frequency signal after generation. It can be sent to the processing end through a relevant device or the radio frequency signal source, or the processing end actively obtains it from the relevant device or the radio frequency signal source, so that the processing end receives the initial radio frequency signal. Here, the acquisition method of the initial radio frequency signal is not further limited.

[0050] After the processing end obtains the initial radio frequency signal, it preferentially splits the initial radio frequency signal to obtain a plurality of sub-radio frequency signals, obtaining multiple sub-radio frequency signals, which is convenient for promptly responding to the demand when there is a demand later, reducing the response time of the demand, and providing multiple sub-radio frequency signals for alleviating the lag in the radio frequency signal amplification work later, providing more choices.

[0051] Among them, the sub-radio frequency signals include a first sub-radio frequency signal and a second sub-radio frequency signal. Figure 2 It is a block diagram of splitting the initial radio frequency signal to obtain a plurality of sub-radio frequency signals provided by an embodiment of the present application. As Figure 2 shown, splitting the initial radio frequency signal to obtain a plurality of sub-radio frequency signals includes the following steps:

[0052] Step S101, obtain historical demand information, and determine the corresponding historical sub-radio frequency signal strength ratio among historical receiving ends based on the historical demand information.

[0053] Step S102, divide the initial radio frequency signal into a first initial radio frequency signal and a second initial radio frequency signal according to a preset ratio, where the strength of the first initial radio frequency signal is greater than that of the second initial radio frequency signal.

[0054] Step S103, split the first initial radio frequency signal according to the historical sub-radio frequency signal strength ratio to obtain corresponding multiple first sub-radio frequency signals.

[0055] Step S104, divide the second initial radio frequency signal into a preset number of second sub-radio frequency signals.

[0056] The above historical demand information refers to the demand information received by the control terminal before. Among them, the quantity of the historical demand information obtained can be determined according to the actual situation. The historical demand information also includes at least one historical receiving end. When the quantity of the historical demand information obtained is one, the intensity ratio between the historical sub-radio frequency signals corresponding to each historical receiving end included in the historical demand information is determined as the historical sub-radio frequency signal intensity ratio corresponding to the historical receiving ends included in the historical demand information.

[0057] When the quantity of the historical demand information obtained is greater than one, the intensity ratio between the historical sub-radio frequency signals corresponding to each historical receiving end included in each historical demand information is determined respectively, and then the intensity ratio obtained by calculating the average value of all the intensity ratios between the historical sub-radio frequency signals is determined as the historical sub-radio frequency signal intensity ratio corresponding to the historical receiving ends included in the historical demand information. For example, when the quantity of the historical demand information obtained is two, the first historical demand information includes historical receiving end A and historical receiving end B, and the intensity ratio between the historical sub-radio frequency signals corresponding to historical receiving end A and historical receiving end B is 1:2. The second historical demand information includes historical receiving end A, historical receiving end C, and historical receiving end D, and the intensity ratio between the historical sub-radio frequency signals corresponding to historical receiving end A and historical receiving end C and historical receiving end D is 1:2:3. Then, any two are selected from the three historical receiving ends included in the second historical demand information as the effective two historical receiving ends included in the second historical demand information, and the intensity ratio between these two effective historical receiving ends is used as the intensity ratio corresponding to the second historical demand information, such as 1:3. Then, the historical sub-radio frequency signal intensity ratio corresponding to the historical receiving ends included in the historical demand information is (1 + 1) / 2:(2 + 3) / 2 = 1:2.5.

[0058] The above preset ratio is pre-stored in the control terminal, and the preset ratio is a:b. Then, the splitter is used to preliminarily divide the initial radio frequency signal into a first initial radio frequency signal and a second initial radio frequency signal, so that the intensity of the first initial radio frequency signal is greater than that of the second initial radio frequency signal. That is, the value of a needs to be much larger than the value of b to ensure that the intensity of the initial radio frequency signal is given to the first initial radio frequency signal as much as possible, so that the subsequent received demand information can be preferably satisfied by relying on the first initial radio frequency signal, and the second initial radio frequency signal is used as a reserve signal.

[0059] After the initial radio frequency signal is preliminarily divided into a first initial radio frequency signal and a second initial radio frequency signal, the first initial radio frequency signal and the second initial radio frequency signal need to be further split respectively. After all, relying only on these two initial radio frequency signals cannot meet the demands of more than two receiving ends subsequently.

[0060] Among them, the first initial radio frequency signal serves as the main radio frequency signal. The first initial radio frequency signal can be divided according to the historical sub-radio frequency signal strength ratio obtained in the above step S101 to obtain corresponding multiple first sub-radio frequency signals. This enables the multiple first sub-radio frequency signals obtained by re-splitting to be more likely to meet the ratio requirements between sub-radio frequency signals in the subsequent demand information, and to better meet the subsequent demand information as much as possible.

[0061] The second initial radio frequency signal serves as the secondary radio frequency signal. The second initial radio frequency signal can be divided according to any ratio to obtain a preset number of second sub-radio frequency signals. This embodiment does not further limit this ratio and the preset number. This is to enable more requirements to be met as much as possible simultaneously and to make full use of the initial radio frequency signal as much as possible.

[0062] Step S200: Receive demand information, where the demand information includes at least one receiving end, and each receiving end corresponds to a sub-radio frequency signal.

[0063] The above demand information refers to the information received by the control end at the same moment when the receiving end sends a demand for receiving a radio frequency signal to the control end. The control end can receive the demand information by the receiving end sending it to the control end. Among them, the demand information includes at least one receiving end, and each receiving end corresponds to a sub-radio frequency signal, that is, the demand information also includes the sub-radio frequency signal corresponding to the included receiving end. This sub-radio frequency signal refers to how strong a radio frequency signal the corresponding receiving end needs to receive.

[0064] Step S300: Based on the demand information, determine the transmission environment for the sub-radio frequency signal corresponding to each receiving end to reach the receiving end, and substitute the transmission environment into a preset model to obtain the signal attenuation information experienced by the sub-radio frequency signal corresponding to each receiving end when reaching the receiving end.

[0065] Since the radio frequency signal will change in intensity due to the influence of the transmission environment during transmission, and different transmission environments have different influences on the radio frequency signal. To ensure that each receiving end can receive the required radio frequency signal, it is necessary to determine the attenuation situation of the radio frequency signal during transmission. And to determine the attenuation situation of the radio frequency signal during transmission, it is necessary to first determine the transmission environment during the transmission of the radio frequency signal. In this way, by sequentially determining the transmission environment and the information attenuation information, it provides an information reference for subsequent determination of signal amplification to determine the degree of signal amplification required. Figure 3 It is a block diagram of determining the transmission environment for the sub-radio frequency signal corresponding to each receiving end to reach the receiving end provided by an embodiment of the present application. As Figure 3 shown, determining the transmission environment for the sub-radio frequency signal corresponding to each receiving end to reach the receiving end based on the demand information includes the following steps:

[0066] Step S301, obtain the required position corresponding to each receiver and the transmission position corresponding to the initial radio frequency signal, substitute the transmission position and the required position into the map software, and receive the transmission position and each required position to obtain a number of line segments.

[0067] Step S302, obtain the environmental information involved in each line segment from the map software, and obtain the weather information corresponding to each line segment from the weather software.

[0068] Step S303, use the environmental information and the weather information as the transmission environment of the receiver corresponding to the line segment.

[0069] The required information also includes the required position corresponding to each receiver included. Therefore, the control terminal can obtain the required position corresponding to each receiver by viewing the required information. And the control terminal stores the position where the radio frequency signal source or other device that generates the initial radio frequency signal is located, that is, the transmission position. Therefore, the control terminal can obtain the transmission position corresponding to the initial radio frequency absorption signal by viewing the stored information. Then the control terminal substitutes both the transmission position and the required position into the connected map software, marks both the required position and the transmission position in the map software, and then enables the map software to connect the transmission position and each required position respectively to obtain a number of line segments. Among them, the number of line segments is equal to the number of required positions.

[0070] The information passed by each of the above-obtained line segments in the map software is the environmental information of the sub-radio frequency signal corresponding to the receiver corresponding to the line segment reaching the receiver. Next, the environmental information corresponding to each line segment can be obtained by viewing the information passed by each line segment. And the line segment position corresponding to each of the above line segments is obtained through the required position and the transmission position. Subsequently, the line segment position is sent to the weather software, and the weather information corresponding to each line segment position is obtained under the processing ability of the weather software itself and sent to the control terminal so that the control terminal can obtain the weather information corresponding to each line segment. Finally, the environmental information and the weather information corresponding to the same line segment are combined together as the transmission environment of the receiver corresponding to the line segment. Among them, the environmental information includes the distance value from the transmission position to the corresponding required position. In this way, on the one hand, factors affecting the signal transmission intensity such as buildings, distances, building properties, weather, humidity, etc. encountered during the signal transmission process are all taken into account, and an attempt is made to comprehensively consider the factors affecting the signal transmission intensity to obtain the transmission environment, which is convenient for more accurately determining the signal attenuation information of the signal subsequently. On the other hand, accessing the map software and the weather software can obtain each transmission environment more accurately and quickly.

[0071] After obtaining the transmission environment of the sub-radio frequency signal corresponding to each receiver reaching the receiver, it is necessary to obtain the signal attenuation information experienced by the sub-radio frequency signal corresponding to each receiver reaching the receiver based on the transmission environment.Figure 4 This is a block diagram of the signal attenuation information experienced by the sub - RF signal corresponding to each receiving end when the transmission environment is substituted into a preset model provided by an embodiment of the present application. As Figure 4 described above, substituting the transmission environment into the preset model to obtain the signal attenuation information experienced by the sub - RF signal corresponding to each receiving end when reaching the receiving end includes the following steps:

[0072] Step S304, determine the required levels corresponding to all receiving ends, where a higher required level indicates that the sub - RF signal needs to be sent to the receiving end earlier.

[0073] Step S305, sort all receiving ends in descending order of the required level to obtain a receiving - end group. Divide the transmission environment corresponding to the first receiving end in the receiving - end group into several sub - transmission information groups according to attributes, where each sub - transmission information group corresponds to a uniquely determined attribute, and in each sub - transmission information group, the sub - transmission environments in the corresponding attribute are stored in the order of the distance from the receiving end from far to near.

[0074] Step S306, form a vertical vector by arranging all sub - transmission information groups according to a preset attribute sequence, use the vertical vector as input information and substitute it into the input end of the preset model, and take the output information output from the output end of the preset model as the signal attenuation information experienced by the sub - RF information corresponding to this receiving end when reaching the receiving end.

[0075] Step S307, when substituting the vertical vector as input information into the input end of the preset model, determine whether the transmission environments corresponding to all receiving ends in the receiving - end group are divided into several sub - transmission information groups according to attributes. If so, generate an end signal to obtain the signal attenuation information experienced by all receiving terminals.

[0076] Step S308, if not, continue to divide the transmission environment corresponding to the next receiving end in the receiving - end group into several sub - transmission information groups according to attributes.

[0077] Specifically, the required information also includes the time requirement or required level of each receiving end for receiving the RF signal. In the case of including the time requirement, the control end can sort in ascending order of time to obtain a time sequence, and determine the receiving ends corresponding to the time requirements from the end to the front in the time sequence as the first required level, the second required level,..., increasing in turn, to determine the required levels corresponding to all receiving ends. In the case of including the required level, directly obtain the required levels corresponding to all receiving ends. Among them, a higher required level indicates that the sub - RF signal needs to be sent to the receiving end earlier.

[0078] Then, all receivers are sorted in descending order of demand level to obtain a receiver group. For example, the receiver group is demand level three, demand level two, and demand level one. Next, the transmission environment corresponding to the first receiver in the receiver group is divided into several sub-transmission information groups according to attributes. For example, the transmission environment corresponding to the first receiver is divided into a sub-transmission information group corresponding to the distance attribute, a sub-transmission information group corresponding to the building attribute, and a sub-transmission information group corresponding to the weather attribute. Among them, each sub-transmission information group contains several sub-transmission information corresponding to the corresponding attribute. Each sub-transmission information corresponds to a section of distance, and the sub-transmission environment in the corresponding attribute is stored in the sub-transmission information group in the order of the distance from the receiver from far to near. Next, all sub-transmission information groups are combined into a vertical vector according to the preset attribute sequence. The preset attribute sequence can specifically be a certain sorting of the distance attribute, the building attribute, and the weather attribute. All sub-transmission information groups corresponding to each receiver are combined into a column vector according to the same attribute sequence. Finally, this column vector is sent as the input information of the preset model to the input end of the preset model, and under the processing of the preset model, the signal attenuation information experienced by the sub-radio frequency information corresponding to this receiver to reach this receiver is output through its output end.

[0079] Among them, during the process of sending the vertical vector corresponding to a receiver in the receiver group to the input end of the preset model for processing, the control end also simultaneously judges whether the transmission environments corresponding to all receivers in the receiver group are divided into several sub-transmission information groups according to attributes. If so, it indicates that the signal attenuation information corresponding to each receiver included in the demand information is obtained. At this time, the control end generates an end signal to obtain the signal attenuation information experienced by all receivers.

[0080] If the transmission environments corresponding to all receivers in the receiver group are not divided into several sub-transmission information groups according to attributes, it indicates that the signal attenuation information corresponding to all information ends included in the demand information that has not been obtained. At this time, when the preset model processes the vertical vector, the control end does not just wait quietly, but continues to divide the transmission environment corresponding to the next receiver in the receiver group into several sub-transmission information groups according to attributes to obtain the signal attenuation information corresponding to this receiver. This can make full use of time to quickly determine the signal attenuation information corresponding to each receiver included in the demand information, thereby indirectly improving the efficiency of the overall radio frequency signal amplification work.

[0081] Among them, the preset model is a BP neural network, which can enable the preset model to process quickly, shorten the time required to determine the signal attenuation information corresponding to each receiver included in the demand information, and thereby indirectly improve the efficiency of the overall radio frequency signal amplification work.

[0082] Step S400: Amplify the corresponding sub - RF signal according to the signal attenuation information to obtain an amplified sub - RF signal.

[0083] Specifically, for each signal attenuation information obtained, add the signal attenuation information to the corresponding sub - RF signal to obtain the signal to be amplified, that is, the amplified sub - RF signal. Then amplify the sub - RF signal corresponding to the signal attenuation information into the amplified sub - RF signal, and then transmit the amplified amplified sub - RF signal so that the corresponding receiving end receives the required signal. It is also possible to perform the above operations separately after obtaining all the signal attenuation information. In this embodiment, it is preferred to perform the relevant amplification work every time a signal attenuation information is obtained. In this way, in this embodiment, the initial RF signal is first split, and then the information for determining the signal amplification required for each branch is determined in real time according to the demand, and finally the corresponding amplification is performed according to the information required for amplification, which can alleviate the lag in the RF signal amplification work.

[0084] Among them, amplifying the corresponding sub - RF signal according to the signal attenuation information to obtain an amplified sub - RF signal includes using electrical components to amplify the sub - RF signal. In this way, the amplification of the RF signal can be achieved at low cost, after all, the cost of electrical components is relatively low.

[0085] In addition, the demand information also includes the required signal strength corresponding to each receiving end. After amplifying the corresponding sub - RF signal according to the signal attenuation information to obtain an amplified sub - RF signal, the following steps are also included:

[0086] Step S500: Send the amplified sub - RF signal to the corresponding receiving end, obtain the actual sub - RF signal received by the receiving end, determine the signal difference between the actual sub - RF signal and the corresponding required signal strength, and judge whether the signal difference meets the preset range. If it meets, generate a reception success signal.

[0087] Step S600: If it does not meet, use the signal difference to adjust the parameters of the last layer of the preset model to achieve online adjustment of the preset model, so as to obtain a new preset model, and update the preset model to the new preset model.

[0088] By receiving the feedback from the receiving end on the intensity of the actually received signal and taking the difference between the intensity of the signal to be received, the signal difference between the two is obtained. Then, by comparing the signal difference with a preset range, if it falls within the preset range, it indicates that the receiving end has received the required radio frequency signal. If it does not fall within the preset range, it indicates that the receiving end has not received the required radio frequency signal, that is, the signal attenuation information obtained in the above step S300 is incorrect. To reduce the impact of subsequent determination of signal attenuation information, the parameters of the last layer of the preset model are also adjusted using the signal difference to achieve online adjustment of the preset model. In this way, only adjusting the parameters of the last layer can quickly achieve adjustment of the preset model, and allows online adjustment to directly obtain a new model, reducing the steps of model replacement and also accelerating the adjustment speed.

[0089] Preferably, it is also determined whether each sub-radio frequency signal corresponds to a receiving end. If not, the sub-radio frequency signal without a corresponding receiving end is stored in an indirect storage manner. Specifically, the indirect storage can be performed by using down-conversion + digitization method, or by using a radio frequency memory, etc. No further limitation is made on the indirect storage method here. In this way, the temporarily unused sub-radio frequency signals are stored first, which can facilitate timely provision when needed later, and can also avoid re-generation, reducing signal waste.

[0090] Preferably, before the amplified sub-radio frequency signal is obtained, if new demand information is received, the sub-radio frequency signal corresponding to the new demand information is selected from the sub-radio frequency signals without a corresponding receiving end, and the transmission environment for the sub-radio frequency signal corresponding to each new receiving end to reach the new receiving end is determined based on the new demand information.

[0091] If the initial radio frequency signal is re-generated before the amplified sub-radio frequency signal is obtained, it will affect the amplification of the sub-radio frequency signal corresponding to the original demand information, so that the receiving end corresponding to the demand information cannot accurately obtain the required signal intensity. At this time, the sub-radio frequency information without a corresponding receiving end after the original splitting operation is taken out from the storage device, and then the operations from step S300 to step S400 are performed on it. Similarly, the new demand information can be satisfied and the amplification of all radio frequency signals can be completed normally, increasing the scalability of the radio frequency signal amplification work.

[0092] Figure 5 It is a schematic connection diagram of an amplification system for radio frequency signals provided by an embodiment of the present application.
