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 digitization 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 being unable to 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 performing the method of radio frequency signals, otherwise it is impossible to determine how much amplification work needs to be done on the radio frequency signals. However, different receiving ends may not be synchronized 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.

Divide the transmission environment corresponding to the first receiver in the receiver 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 order of the distance from the receiver from far to near; Form a vertical vector by arranging all sub - transmission information groups according to a preset attribute sequence.

If so, generate an end signal to obtain the signal attenuation information experienced by all receiving ends; 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.

If it satisfies, generate a reception - success signal; If it does not satisfy, use the signal difference to adjust the parameters of the last layer of the preset model to achieve online adjustment of the preset model, obtain a new preset model, and update the preset model to the new preset model.

[0020] To more clearly understand the purpose, technical solution, and advantages of the present application, the present application will be described and explained below in conjunction with 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.

[0021] The embodiments of the present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0022] Figure 1 It is a block diagram of a method for amplifying radio frequency signals provided by an embodiment of the present application. As Figure 1 shown, a method for amplifying radio frequency signals includes the following steps: Step S100, obtain an initial radio frequency signal, and split the initial radio frequency signal to obtain a plurality of sub-radio frequency signals.

[0023] The embodiments of the present application are described from the perspective of the processing end. The above-mentioned initial radio frequency signal refers to the radio frequency signal generated by a radio frequency signal source or other devices, that is, the radio frequency signal that has not been processed after generation. The processing end can receive the initial radio frequency signal by means of sending it to the processing end through relevant devices or the radio frequency signal source, or by the processing end actively obtaining it from relevant devices or the radio frequency signal source. Here, the acquisition method of the initial radio frequency signal will not be further limited.

[0024] 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, providing multiple sub-radio frequency signals for alleviating the lag in the radio frequency signal amplification work later, and providing more choices.

[0025] Among them, the sub-radio frequency signals include a first sub-radio frequency signal and a second sub-radio frequency signal. Figure 2It is a block diagram for splitting an initial radio frequency signal to obtain several sub-radio frequency signals provided by an embodiment of the present application. As Figure 2 shown, splitting the initial radio frequency signal to obtain several sub-radio frequency signals includes the following steps: Step S101, obtain historical demand information, and determine the historical sub-radio frequency signal strength ratio corresponding to the historical receiving ends included in the historical demand information based on the historical demand information.

[0026] 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.

[0027] 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.

[0028] Step S104, divide the second initial radio frequency signal into a preset number of second sub-radio frequency signals.

[0029] The above historical demand information refers to the demand information received by the control end before. Among them, the quantity of the obtained historical demand information 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 obtained historical demand information is one, the strength 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 strength ratio corresponding to the historical receiving ends included in the historical demand information.

[0030] When the number of historical demand information obtained is greater than one, the intensity ratios between the historical sub-radio frequency signals corresponding to each historical receiving end included in each historical demand information are determined respectively, and then the intensity ratio obtained by calculating the average value of the intensity ratios between all historical sub-radio frequency signals is determined as the intensity ratio of the historical sub-radio frequency signals corresponding to the historical receiving ends included in the historical demand information. For example, if the number of 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 ends A, C, and D, and the intensity ratios between the historical sub-radio frequency signals corresponding to historical receiving end A and historical receiving ends C and D are 1:2:3. Then, any two of the three historical receiving ends included in the second historical demand information are selected as the two valid historical receiving ends included in the second historical demand information, and the intensity ratio between these two valid historical receiving ends is used as the intensity ratio corresponding to the second historical demand information, such as 1:3. Then, the intensity ratio of the historical sub-radio frequency signals corresponding to the historical receiving ends included in the historical demand information is (1 + 1) / 2:(2 + 3) / 2 = 1:2.5.

[0031] The above preset ratio is pre-stored in the control end, 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 the first initial radio frequency signal, and the second initial radio frequency signal is used as a reserve signal.

[0032] 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, because relying only on these two initial radio frequency signals cannot meet the requirements of more than two receiving ends subsequently.

[0033] Among them, the first initial radio frequency signal is used as the main radio frequency signal, and the first initial radio frequency signal can be divided according to the intensity ratio of the historical sub-radio frequency signals obtained in the above step S101 to obtain corresponding multiple first sub-radio frequency signals. This makes it more likely that the multiple first sub-radio frequency signals obtained by further splitting can meet the ratio requirements of the sub-radio frequency signals in the subsequent demand information and better meet the subsequent demand information.

[0034] The second initial radio frequency signal is a 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. In this way, when there are more requirements, it is possible not only to meet their requirements as much as possible simultaneously, but also to make full use of the initial radio frequency signal as much as possible.

[0035] Step S200: Receive requirement information, where the requirement information includes at least one receiving end, and each receiving end corresponds to a sub-radio frequency signal.

[0036] The above-mentioned requirement information refers to the information received by the control end at the same moment when the receiving end has a requirement to receive a radio frequency signal and sends it to the control end. The control end can receive the requirement information by the receiving end sending it to the control end. Among them, the requirement information includes at least one receiving end, and each receiving end corresponds to a sub-radio frequency signal, that is, the requirement information also includes the sub-radio frequency signal corresponding to the included receiving end. The sub-radio frequency signal refers to how strong a radio frequency signal the corresponding receiving end needs to receive.

[0037] Step S300: Based on the requirement information, determine the transmission environment for each 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 each sub-radio frequency signal corresponding to each receiving end when reaching the receiving end.

[0038] Since the radio frequency signal will change in intensity due to the influence of the transmission environment during the transmission process, and different transmission environments have different influences on the radio frequency signal. In order to determine 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 the transmission process, and to determine the attenuation situation of the radio frequency signal during the transmission process, it is necessary to first determine the transmission environment during the transmission process 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 determining the amplification of the signal later, so as to determine what degree of amplification the signal needs. Figure 3 It is a block diagram of determining the transmission environment for each 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 each sub-radio frequency signal corresponding to each receiving end to reach the receiving end based on the requirement information includes the following steps: Step S301: Obtain the required position corresponding to each receiving end and the sending position corresponding to the initial radio frequency signal, substitute the sending position and the required position into the map software, and receive the sending position and each required position to obtain a number of line segments.

[0039] 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.

[0040] Step S303: Use the environmental information and weather information as the transmission environment of the receiving end corresponding to the line segment.

[0041] The demand information also includes the demand location corresponding to each receiving end included. Therefore, the control end can obtain the demand location corresponding to each receiving end by checking the demand information. And the control end stores the location where the radio frequency signal source or other device that generates the initial radio frequency signal is located, that is, the transmission location. Therefore, the control end can obtain the transmission location corresponding to the initial radio frequency absorption signal by checking the stored information. Then, the control end substitutes both the transmission location and the demand location into the connected map software, marks both the demand location and the transmission location in the map software, and then makes the map software connect the transmission location with each demand location respectively to obtain several line segments. Among them, the number of line segments is equal to the number of demand locations.

[0042] 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 receiving end of the line segment reaching the receiving end. Next, the environmental information corresponding to each line segment can be obtained by checking the information passed by each line segment. And the line segment location corresponding to each of the above line segments is obtained through the demand location and the transmission location. Subsequently, the line segment location is sent to the weather software, and the weather information corresponding to each line segment location is obtained under the processing ability of the weather software and sent to the control end so that the control end can obtain the weather information corresponding to each line segment. Finally, the environmental information and weather information corresponding to the same line segment are combined together as the transmission environment of the receiving end corresponding to the line segment. Among them, the environmental information includes the distance value from the transmission location to the corresponding demand location. 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 taken into account, and as comprehensive as possible factors affecting the signal transmission intensity are considered 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.

[0043] After obtaining the transmission environment of the sub-radio frequency signal corresponding to each receiving end reaching the receiving end, it is necessary to obtain the signal attenuation information experienced by the sub-radio frequency signal corresponding to each receiving end reaching the receiving end based on the transmission environment. Figure 4 It is a block diagram of substituting 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 reaching the receiving end provided by an embodiment of the present application. As Figure 4 described, substituting 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 reaching the receiving end includes the following steps: Step S304: Determine the requirement levels corresponding to all receivers. Here, a higher requirement level indicates that the sub-radio frequency signal needs to be sent to the receiver earlier.

[0044] Step S305: Sort all receivers in descending order of requirement 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. Here, 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 receiver from far to near.

[0045] Step S306: Combine all sub-transmission information groups into a vertical vector according to a preset attribute sequence. Substitute the vertical vector as input information into the input end of a 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-radio frequency information corresponding to this receiver when reaching the receiver.

[0046] 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 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 receiving terminals.

[0047] Step S308: 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.

[0048] Specifically, the requirement information also includes the time requirement or requirement level of each included receiver for receiving the radio frequency signal. In the case of including time requirements, the control end can sort them in ascending order of time to obtain a time sequence, and determine the receivers corresponding to the time requirements from the back to the front in the time sequence as the first requirement level, the second requirement level,..., increasing in turn, to determine the requirement levels corresponding to all receivers. In the case of including requirement levels, directly obtain the requirement levels corresponding to all receivers. Here, a higher requirement level indicates that the sub-radio frequency signal needs to be sent to the receiver earlier.

[0049] Then, all the receivers are sorted in descending order according to the requirement level to obtain a receiver group. For example, the receiver group is requirement level three, requirement level two, and requirement level one. Then, 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 environments in the corresponding attribute are stored in the sub-transmission information group in the order of the distance from the receiver from far to near. Next, all the 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 the 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.

[0050] 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 the 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 the receivers.

[0051] If the transmission environments corresponding to not all the receivers in the receiver group are divided into several sub-transmission information groups according to attributes, it indicates that the signal attenuation information corresponding to all the information terminals 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 overall efficiency of completing the radio frequency signal amplification work.

[0052] 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 overall efficiency of completing the radio frequency signal amplification work.

[0053] Step S400: Amplify the corresponding sub - RF signal according to the signal attenuation information to obtain an amplified sub - RF signal.

[0054] Specifically, for each obtained signal attenuation information, add this 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 this signal attenuation information into the amplified sub - RF signal. Subsequently, transmit the amplified amplified sub - RF signal so that the corresponding receiving end can receive 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, this embodiment first performs a splitting operation on the initial RF signal, then determines in real - time according to the demand the information for amplifying the signal for each branch, and finally performs the corresponding amplification according to the information for amplification required, which can alleviate the hysteresis existing in the RF signal amplification work.

[0055] 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 work of the RF signal can be realized at low cost, after all, the cost of electrical components is relatively low.

[0056] 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: 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.

[0057] Step S600: 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, so as to obtain a new preset model, and update the preset model to the new preset model.

[0058] 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 the 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.

[0059] 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 the down-conversion + digitization method, or by using a radio frequency memory, etc. The indirect storage method is not further limited here. In this way, the temporarily unused sub-radio frequency signals can be stored first, which is convenient for timely provision when needed later and can also avoid regenerating them, reducing signal waste.

[0060] Preferably, before the amplified sub-radio frequency signal is obtained, if a 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 each sub-radio frequency signal corresponding to the new receiving end to reach the new receiving end is determined based on the new demand information.

[0061] If the initial radio frequency signal is regenerated 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, resulting in the receiving end corresponding to the demand information being unable to 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 normally completed, increasing the scalability of the radio frequency signal amplification work.

[0062] Figure 5 It is a schematic connection diagram of a radio frequency signal amplification system provided by an embodiment of the present application. As Figure 5 shown, a radio frequency signal amplification system includes: a splitting module, an acquisition module, a processing module, and an amplification module.

[0063] Among them, the splitting module is used to obtain an initial radio frequency signal and split the initial radio frequency signal to obtain a plurality of sub-radio frequency signals. The obtaining module is used to receive requirement information, where the requirement information includes at least one receiving end, and each receiving end corresponds to a sub-radio frequency signal.
