Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Wireless communication is a communication method for exchanging information by utilizing the characteristic that radio wave signals can propagate in free space. Wireless communication implemented in mobile is also commonly referred to as mobile communication, and both are collectively referred to as wireless mobile communication. In brief, wireless communication is a communication method using only electromagnetic waves without using cables.
All wireless signals are transmitted through the air along with electromagnetic waves, and the electromagnetic waves are energy waves consisting of an electronic part and an energy part. Sound and light are two examples of electromagnetic waves. Waves in the wireless spectrum (that is, waves used for broadcast, cellular telephone, and satellite transmissions) are invisible and inaudible, at least until decoded by a receiver.
The "radio spectrum" is a continuum of electromagnetic waves for telecommunications, the waves having different frequencies and wavelengths. The wireless spectrum includes frequencies between 9khz and 300000 Ghz. Each wireless service is associated with a certain region of wireless spectrum. For example, AM broadcasting involves the low end frequencies of the wireless communication spectrum, using frequencies between 535 and 1605 khz.
The radio spectrum is a subset of the entire electromagnetic spectrum. Electromagnetic waves with higher or lower frequencies are also present in nature, but they are not used for telecommunication. Frequencies below 9kz are used for specialized applications such as wildlife tracking or garage door switches. Electromagnetic waves with frequencies above 300000Ghz are visible to humans, and for this reason they cannot be used for communication over the air. For example, we recognize an electromagnetic wave with a frequency of 428570Ghz as red.
Example 1
Fig. 1 is a flow chart illustrating a wireless signal processing method, and in an embodiment of the present invention, the method includes:
step S100: the method comprises the steps that wireless signals are received in real time in a preset frequency range on the basis of an antenna, the wireless signals are converted into a oscillogram, and the oscillogram is input into a cache region;
the purpose of step S100 is to receive wireless signals, which are buffered, and which are time-based bands at the time of reception, convert these line numbers into a waveform diagram, whose horizontal axis is time, and store the waveform diagram. It should be noted that the waveform length of the oscillogram is limited, for example, a period of time corresponds to a oscillogram, and the oscillogram is inserted into the buffer according to the time information during storage.
Step S200: extracting the oscillogram in the cache region, and decoding the oscillogram based on a main decoder to obtain wireless data;
the waveform represents a wireless signal from which the process of generating wireless data is decoding.
Step S300: acquiring decoding data of a main decoder in real time, and copying the decoding data to a secondary decoder; wherein the number of the secondary decoders is at least one; the decoding data comprises working parameters of a main decoder and wireless data;
two independent signal processing units are arranged, the respective signal processing processes are mutually independent, and as long as a wireless signal with a certain time length is cached in the signal caching unit, even if any party fails, the signal processing of the other party is not influenced; the two independent signal processing units are the primary decoder and the secondary decoder. If it is desired that the two decoders can be switched at the first time, it is required that the decoding schedules of the two decoders are the same, but they are not independent decoding which must have a hysteresis phenomenon due to different performances of the devices, and therefore, the above-mentioned contents are copied to keep the decoding schedules of the two decoders the same.
Step S400: performing characteristic analysis on the decoded data, and switching the priority of a main decoder and the priority of an auxiliary decoder according to the characteristic analysis result;
when a failure occurs, the priority of the primary decoder and the secondary decoder is switched, and the decoding element with the higher priority is used as the decoding element and the backup element with the lower priority is used as the backup element. It is worth mentioning that there is also a implicit meaning in the above that the primary and secondary decoders function almost identically, the primary and secondary scores being determined by the reality.
Fig. 2 is a first sub-flowchart of a wireless signal processing method, which receives a wireless signal in real time in a preset frequency range based on an antenna, converts the wireless signal into a waveform diagram, and inputs the waveform diagram into a buffer area, where the step includes steps S101 to S104:
step S101: detecting a wireless signal in real time based on an antenna, and filtering the wireless signal according to a preset frequency range;
step S102: identifying intensity parameters in the filtered wireless signals, and classifying the filtered wireless signals according to the intensity parameters;
step S103: generating a plurality of sections of waveforms according to the classified wireless signals, and respectively fitting the plurality of sections of waveforms to obtain a waveform diagram containing the plurality of sections of fitted waveforms;
step S104: and inserting the oscillogram into a buffer area according to the time information in the oscillogram.
The signal propagates through the air until it reaches the target location. At the target location, another antenna receives the signal and a receiver converts it back into a current. Antennas are required for both receiving and transmitting signals, and are classified into omni-directional antennas and directional antennas. Due to the influence of reflection, diffraction and scattering in the propagation of signals, wireless signals can reach the destination of the wireless signals along a plurality of different paths to form multipath signals; the signal strengths of these multipath signals are different and therefore the waveform pattern tends to be a multi-segment waveform. In addition, there may be some undetected or over-discretized points in the waveforms, and the smoothing operation is performed by fitting these points.
Fig. 3 shows a second sub-flowchart of the wireless signal processing method, where the step of extracting the waveform map in the buffer and decoding the waveform map based on the main decoder to obtain the wireless data includes steps S201 to S204:
step S201: extracting a oscillogram in the cache region, respectively carrying out stability analysis on a plurality of sections of waveforms in the oscillogram, and determining the stability level of the plurality of sections of waveforms according to the stability analysis result;
step S202: screening waveforms with stability levels larger than a preset stability threshold, and decoding the screened waveforms based on a main decoder to obtain initial detection data;
step S203: comparing the initial inspection data, and determining a problem point position according to a comparison result;
step S204: and extracting corresponding wave bands in all the multi-segment waveforms according to the problem point positions, decoding the corresponding wave bands based on main decoding, and generating wireless data according to decoding results and the initial check data.
In the decoding process, the decoding results of the plurality of waveforms should be approximately constant, because the waveforms are different only in amplitude, and the signals of the waveform signals are the fluctuation conditions of the waveforms, therefore, some waveforms with higher stability are screened and decoded. It should be noted that, for some bands, the identification results of multiple waveforms are different, and it is necessary to identify the corresponding positions of all waveforms, and finally determine a more accurate value.
Fig. 4 shows a third sub-flow diagram of a wireless signal processing method, wherein the step of acquiring decoded data of a primary decoder in real time and copying the decoded data to a secondary decoder comprises steps S301 to S304:
step S301: establishing a connection channel between the auxiliary decoder and the main decoder to obtain working parameters of the main decoder;
step S302: connecting the working parameters with the wireless data obtained by the main decoder based on time information to obtain decoded data, and synchronizing decoding into the auxiliary decoder;
step S303: detecting a decoding node in a main decoder in real time, and when the decoding node is detected, carrying out anomaly analysis on synchronous data in a secondary decoder and decoded data in the main decoder;
step S304: when the abnormal analysis result is normal, the synchronous data is cut to a storage area; wherein the decoding node is generated by a master decoder from a waveform map.
In the above, the main decoder serves as a decoding working end, on one hand, it generates wireless data obtained by decoding, and on the other hand, it autonomously generates working parameters, and these working parameters and wireless data together form decoded data, and these decoded data are analyzed, so that the decoding state can be determined.
Fig. 5 shows a fourth sub-flow diagram of a wireless signal processing method, wherein the step of performing a feature analysis on the decoded data and switching the priorities of the primary decoder and the secondary decoder according to the feature analysis result comprises steps S401 to S404:
step S401: extracting wireless data in the decoded data, and calculating the data volume of the wireless data according to a preset time threshold; the wireless data unit is a network data packet;
step S402: generating a fluctuation table corresponding to the decoded data according to the data amount;
step S403: extracting working parameters in the decoded data, inputting the working parameters into a trained mapping model, and determining a reference table;
step S404: and comparing the fluctuation table with the reference table, and switching the priority of the main decoder and the auxiliary decoder according to the comparison result.
The wireless data are usually network data packets and discrete data, the size of the discrete data is calculated, a fluctuation table reflecting the transmission process can be generated, then, a reference table can be obtained according to the working parameters of the main decoder, namely, theoretically what the wireless data should be, the mapping model can be completed in the step, the determination process of the mapping model is also simple, samples are collected, and then fitting is carried out.
Finally, the fluctuation table and the reference table are compared, and the possibility of the main decoder failing can be judged.
Fig. 6 shows a fifth sub-flowchart of the wireless signal processing method, wherein the step of comparing the fluctuation table with the reference table and switching the priority of the primary decoder and the secondary decoder according to the comparison result comprises steps S4011 to S4013:
step S4011: reading the table parameters of the fluctuation table, and verifying the reference table according to the table parameters;
step S4012: when the reference table is verified, generating an offset table based on the reference table according to the fluctuation table and the reference table; wherein the number of element entries of the fluctuation table, the reference table and the offset table is the same; the elements in the offset table are offset rates relative to data in a reference table;
step S4013: traversing the offset table, marking elements larger than a preset offset threshold value, generating a mark number, and taking the secondary decoder as a primary decoder when the mark number reaches the preset number threshold value.
The architecture of the reference table and the fluctuation table should be the same, i.e. the data structure and the number of element entries are the same, so the process of calculating the offset table is very easy, and can be analogized to the operation of a matrix; the elements in the offset table are offset rates, and if the number of elements with larger offset rates reaches a certain level, it can be considered that the main decoder has a problem, and then the sub-decoder is used as the main decoder, and accordingly, the original main decoder can be used as the sub-decoder, and other sub-decoders can be connected externally.
