[0051] See also Figure 1 , showing a multi-protocol wireless signal processing device provided in an embodiment of the present application, the multi-protocol wireless signal processing device includes a broadband receiver and a multi-protocol wireless signal processing system, wherein the multi-protocol wireless signal processing system includes a channelizer and multiple detectors.

[0052] In an embodiment of the present application, the main function of the broadband receiver is to be able to collect broadband signals of sufficient bandwidth at one time within the working frequency band range (30Mhz-6Ghz) used in drone communication, and output the collected broadband signals to the multi-protocol wireless signal processing system; the detector can register with the channelizer to provide its desired registration request, so that the channelizer can feedback the corresponding narrowband signal to the detector based on the registration request provided by the detector; wherein the registration request provided by the detector includes a channel list, the channel bandwidth of the detector, the input data sampling frequency and the data callback function of the detector; the channelizer can adjust the broadband receiver according to the registration request provided by the detector to complete the corresponding broadband signal acquisition.

[0053] Accordingly, the present application embodiment provides a multi-protocol wireless signal processing method, such as Figure 2 As shown, the multi-protocol wireless signal processing method is applied to a channelizer in a multi-protocol wireless signal processing system, and the multi-protocol wireless signal processing method specifically includes the following steps:

[0054] S201: receiving a registration request sent by at least one detector; the registration request of the detector includes at least a channel list, a channel bandwidth and a data callback function of the detector, and the channel list includes at least one central frequency point.

[0055] In the process of specifically executing step S201, at least one detector in the multi-protocol wireless signal processing system can provide its desired registration request when registering with the channelizer, wherein the registration provided by the detector may include a channel list, the channel bandwidth of the detector, the input data sampling rate, the minimum sampling duration and the data callback function of the detector; the channel list includes at least one center frequency point.

[0056] It should be noted that the center frequency can be 2410Mhz, 2430Mhz, etc.; the channel bandwidth of the detector can be 10Mhz, 20Mhz, etc.; the input data sampling rate can be 10M samples / s, 15M samples / s, etc.; the minimum sampling duration can be 10ms, 20ms, etc.; the data callback function of the detector can be chan_data_procA(), chan_data_procB(), etc., and the embodiment of the present application does not limit the center frequency, channel bandwidth, input data sampling rate, minimum sampling duration, and data callback function.

[0057] S202: Generate a channel list according to each central frequency point, and determine whether the channelizer meets the single signal acquisition condition according to the channel list and the maximum bandwidth of the wideband receiver. If the channelizer does not meet the single signal acquisition condition, execute step S203; if the channelizer meets the single signal acquisition condition, execute step S205.

[0058] In the specific process of executing step S202, after receiving the registration request sent by at least one detector, the channelizer can generate a channel list list from each center frequency point in the channel list in each received registration request in the order from the smallest to the largest, so as to judge whether the channelizer meets the single signal acquisition condition according to the maximum bandwidth of the wideband receiver, the highest center frequency point and the lowest center frequency point in the channel list list; if the channelizer does not meet the single signal acquisition condition, execute step S203; if the channelizer meets the single signal acquisition condition, execute step S205. Among them, the highest center frequency point in the channel list list is the maximum value of each center frequency point in the channel list list, and the lowest center frequency point is the minimum value of each center frequency point in the channel list list.

[0059] For example, the channelizer receives registration requests sent by detector A and detector B; wherein the channel list in the registration request sent by detector A includes central frequencies such as 2410Mhz, 2420Mhz, 2430Mhz and 2440Mhz, and the channel list in the registration request sent by detector B includes central frequencies such as 2440Mhz, 2450Mhz, 2460Mhz and 2470Mhz; a channel list list (2410Mhz, 2420Mhz, 2430Mhz, 2440Mhz, 2440Mhz, 2450Mhz, 2460Mhz, 2470Mhz) is generated by ordering the central frequencies in the channel lists in the registration requests sent by detector A and detector B from small to large.

[0060] Optionally, the process of judging whether the channelizer meets the single signal acquisition condition according to the channel list and the maximum bandwidth of the wideband receiver can be specifically as follows: calculating the frequency band sampling range corresponding to the channel list according to the highest center frequency and the lowest center frequency in the channel list; judging whether the frequency band sampling range is greater than the maximum bandwidth of the wideband receiver; if the frequency band sampling range is greater than the maximum bandwidth of the wideband receiver, determining that the channelizer does not meet the single signal acquisition condition; if the frequency band sampling range is not greater than the maximum bandwidth of the wideband receiver, determining that the channelizer meets the single signal acquisition condition.

[0061] It should be noted that the frequency band sampling range of the channel list can be calculated based on the highest center frequency and the lowest center frequency in the channel list. If the frequency band sampling range is not greater than the maximum bandwidth of the broadband receiver, it means that a single sampling of the broadband receiver can cover all center frequencies in the channel list, and it can be determined that the channelizer meets the single signal acquisition conditions; if the frequency band sampling range is greater than the maximum bandwidth of the broadband receiver, it means that a single sampling of the broadband receiver cannot cover all center frequencies in the channel list, and it can be determined that the channelizer does not meet the single signal acquisition conditions.

[0062] As a preferred method of an embodiment of the present application, the process of calculating the frequency band sampling range corresponding to the channel list according to the highest center frequency and the lowest center frequency in the channel list can be specifically as follows: determining the highest center frequency and the lowest center frequency in the channel list; calculating the highest sampling frequency corresponding to the channel list according to the channel bandwidth of the detector corresponding to the highest center frequency and the highest center frequency, and calculating the lowest sampling frequency corresponding to the channel list according to the channel bandwidth of the detector corresponding to the lowest center frequency and the lowest center frequency; determining the frequency band sampling range corresponding to the channel list according to the highest sampling frequency and the lowest sampling frequency.

[0063] In actual application, the channelizer can determine the highest center frequency and the lowest center frequency in the channel list, as well as determine the detector corresponding to the highest center frequency and the detector corresponding to the lowest center frequency; calculate half of the channel bandwidth of the detector corresponding to the highest center frequency and half of the channel bandwidth of the detector corresponding to the lowest center frequency; calculate the sum of the highest center frequency and half of the channel bandwidth of the detector corresponding to the highest center frequency to obtain the highest sampling frequency corresponding to the channel list; calculate the sum of the lowest center frequency and half of the channel bandwidth of the detector corresponding to the lowest center frequency to obtain the lowest sampling frequency corresponding to the channel list, and finally calculate the difference between the highest sampling frequency and the lowest sampling frequency to obtain the frequency band sampling range of the channel list.

[0064] For example, the highest center frequency in the channel list is 2460Mhz, the lowest center frequency is 2410Mhz, the channel bandwidth of the detector corresponding to the highest center frequency is 20Mhz, and the channel bandwidth of the detector corresponding to the lowest center frequency is 10Mhz; the calculation method for determining the frequency band sampling range of the channel list can be: the highest sampling frequency (2460+20 / 2=2470)-the lowest sampling frequency (2410-10 / 2=2405)=65Mhz (frequency band sampling range); if the maximum bandwidth of the broadband receiver is 56Mhz, then To determine that the frequency band sampling range of the channel list is greater than the maximum bandwidth of the broadband receiver, and further it can be determined that a single acquisition of the broadband receiver cannot cover all the center frequency points in the channel list, that is, it can be determined that the channelizer does not meet the single signal acquisition conditions; if the maximum bandwidth of the broadband receiver is 80Mhz, it can be determined that the frequency band sampling range of the channel list is not greater than the maximum bandwidth of the broadband receiver, and further it can be determined that a single acquisition of the broadband receiver can cover all the center frequency points in the channel list, that is, it can be determined that the channelizer meets the single signal acquisition conditions.

[0065] S203: Determine a sampling center frequency point for each round of sampling according to the channel list, and determine at least one channel covered by each round of sampling according to the sampling center frequency point for each round of sampling and the maximum bandwidth of the wideband receiver.

[0066] In the specific process of executing step S203, when the channelizer determines that a single acquisition cannot cover all the central frequency points in the channel list, that is, when it determines that the single signal acquisition condition is not met, the sampling central frequency point of the Nth round of sampling can be determined according to the channel list, and at least one central frequency point covered by the Nth round of sampling can be determined according to the sampling central frequency point of the Nth round of sampling and the maximum bandwidth of the wideband receiver, and at least one channel covered by the Nth round of sampling can be determined according to the at least one central frequency point covered by the Nth round of sampling; if there are still central frequencies in the channel list after excluding at least one central frequency point covered by the Nth round of sampling, N is controlled to increase by 1, so as to re-determine the sampling central frequency point of the Nth round of sampling according to the channel list (the channel list after excluding at least one central frequency point covered by the Nth round of sampling), and at least one central frequency point covered by the Nth round of sampling can be determined according to the sampling central frequency point of the Nth round of sampling and the maximum bandwidth of the wideband receiver, until there are no central frequencies in the channel list; wherein N is greater than or equal to 1.

[0067] It should be noted that a channel corresponding to a central frequency point covered by the Nth round of sampling may be determined as a channel covered by the Nth round of sampling.

[0068] Optionally, the process of determining the sampling center frequency of each round of sampling according to the channel list, and determining at least one channel covered by each round of sampling according to the sampling center frequency of each round of sampling and the maximum bandwidth of the wideband receiver can be specifically as follows: determining the lowest center frequency from the channel list; calculating the lower limit sampling frequency of the Nth round of sampling according to the lowest center frequency, and calculating the sampling center frequency of the Nth round of sampling according to the lower limit sampling frequency of the Nth round of sampling; N is greater than or equal to 1; determining the sampling range of the Nth round of sampling according to the sampling center frequency of the Nth round of sampling, and determining the sampling range of the Nth round of sampling according to the sampling range and the channel The channel bandwidth of the detector corresponding to each center frequency point in the list list determines at least one center frequency point covered by the Nth round of sampling from the channel list list, and determines at least one channel covered by the Nth round of sampling according to at least one center frequency point covered by the Nth round of sampling; at least one center frequency point covered by the Nth round of sampling is eliminated from the channel list list; if there are still center frequencies in the channel list list after eliminating at least one center frequency point covered by the Nth round of sampling, control N to increase by 1, and execute to determine the lowest center frequency point from the channel list list until there are no center frequencies in the channel list list.

[0069] As a preferred method of an embodiment of the present application, the process of calculating the lower limit sampling frequency of the Nth round of sampling according to the lowest center frequency, and calculating the sampling center frequency of the Nth round of sampling according to the lower limit sampling frequency of the Nth round of sampling can be specifically as follows: calculating the lower limit sampling frequency of the Nth round of sampling according to the lowest center frequency and the channel bandwidth of the detector corresponding to the lowest center frequency; calculating the sampling center frequency of the Nth round of sampling according to the lower limit sampling frequency of the Nth round of sampling and the maximum bandwidth of the wideband receiver.

[0070] In some embodiments, the lowest center frequency in the channel list and the detector corresponding to the lowest center frequency can be determined first, and half of the channel bandwidth of the detector corresponding to the lowest center frequency can be calculated, so as to calculate the difference between the lowest center frequency and half of the channel bandwidth of the detector corresponding to the lowest center frequency, and obtain the lower limit sampling frequency of the Nth round of sampling; calculate half of the maximum bandwidth of the wideband receiver, and calculate the sum of the lower limit sampling frequency in the channel list and half of the maximum bandwidth of the wideband receiver to obtain the sampling center frequency of the Nth round of sampling, so as to use the sampling center frequency of the Nth round of sampling as a reference, expand half of the maximum bandwidth of the wideband receiver upward and expand half of the maximum bandwidth of the wideband receiver downward respectively, to obtain the sampling range of the Nth round of sampling, and determine at least one center frequency covered by the Nth round of sampling from each center frequency band of the channel list according to the sampling range of the Nth round of sampling and the channel bandwidth of the detector corresponding to each center frequency in the channel list, and determine at least one channel covered by the Nth round of sampling according to at least one center frequency covered by the Nth round of sampling.

[0071] For example, the channel list is 2410Mhz, 2420Mhz, 2430Mhz, 2440Mhz, 2440Mhz, 2450Mhz, 2460Mhz, 2470Mhz, where the channel bandwidth of the detector corresponding to 2410Mhz, 2420Mhz, 2430Mhz and 2440Mhz is 10Mhz; the channel bandwidth of the detector corresponding to 2440Mhz, 2450Mhz, 2460Mhz and 2470Mhz is 20Mhz; at this time, it can be determined from the channel list that the lowest center frequency is 2410Mhz; if the channel bandwidth of the detector corresponding to the lowest center frequency is 10Mhz, the lower limit sampling frequency of the first round of sampling can be calculated as: 2410-10 / 2=2405Mhz; if the maximum bandwidth of the bandwidth receiver is 56Mhz, it can be calculated The center frequency of the first round of sampling is calculated to be 2405+56 / 2=2433. Taking the sampling center frequency (2433Mhz) of the first round of sampling as a reference, half of the maximum bandwidth of the wideband receiver (28Mhz) is expanded upward and half of the maximum bandwidth of the wideband receiver (28Mhz) is expanded downward, respectively, so that the sampling range of the first round of sampling is 2405Mhz~2461Mhz. Then, according to the sampling range of the first round of sampling and the channel bandwidth of the detector corresponding to each center frequency in the channel list, it can be determined from the channel list that the center frequency covered by the first round of sampling includes 2410Mhz, 2420Mhz, 2430Mhz, 2440Mhz, 2440Mhz, and 2450Mhz. According to at least one center frequency covered by the first round of acquisition, at least one channel covered by the first round of sampling is determined. Among them, although the center frequency 2460Mhz in the channel list is also within the sampling range of the first round of sampling, since the detected channel bandwidth corresponding to the center frequency 2460Mhz is 20Mhz, it can be seen that the first round of sampling cannot cover the channel corresponding to the center frequency 2460Mhz. Therefore, the first round of sampling cannot cover the center frequency 2460.

[0072] Eliminate the center frequencies covered by the first round of sampling from the channel list. At this time, it can be found that there are still center frequencies in the channel list, and then the sampling center frequencies and covered center frequencies of the second round of sampling can be determined. Specifically, the lowest center frequency is determined to be 2460Mhz from the channel list; if the channel bandwidth of the detector corresponding to the lowest center frequency is 20Mhz, the lower limit sampling frequency of the second round of sampling can be calculated as: 2460-20 / 2=2450Mhz; if the maximum bandwidth of the bandwidth receiver is 56Mhz, the center frequency of the second round of sampling can be calculated as 2450+56 / 2=2478. Taking the sampling center frequency point (2478Mhz) of the sample as the benchmark, half of the maximum bandwidth of the broadband receiver is expanded upward (28Mhz) and half of the maximum bandwidth of the broadband receiver is expanded downward (28Mhz), and the sampling range of the first round of sampling is obtained to be 2450Mhz~2506Mhz. Then, according to the sampling range of the second round of sampling and the channel bandwidth of the detector corresponding to each center frequency point in the channel list, it can be determined from the channel list that the center frequency points covered by the second round of sampling include 2460Mhz and 2470Mhz, and at least one channel covered by the second round of sampling is determined according to at least one center frequency point covered by the second round of sampling.

[0073] S204: For each round of sampling, the broadband signal sent by the broadband receiver is processed according to each channel covered by the round of sampling to obtain a narrowband signal corresponding to each channel covered by the round of sampling, and the narrowband signal corresponding to each channel covered by the round of sampling is fed back to the corresponding detector.

[0074] In the specific process of executing step S204, after the channelizer determines the sampling center frequency of each round of sampling and at least one channel covered, for each round of sampling, the sampling center frequency of the round of sampling can be sent to the broadband receiver, so that the broadband receiver collects the corresponding broadband signal based on the received sampling center frequency. At this time, the broadband signal collected by the broadband receiver can cover all channels covered by the round of sampling, and all channels covered by the round of sampling can correspond to multiple detectors, that is, the broadband signal collected by the broadband receiver can cover the signals required by multiple detectors, thereby solving the problem in the prior art that the detectors are designed for a specific single communication protocol and cannot be applied to drone signals of various communication protocols.

[0075] When the channelizer receives the broadband signal collected and sent by the broadband receiver based on the sampling center frequency of this round of sampling, it can calculate the frequency deviation between the center frequency corresponding to each channel covered by this round of sampling and the sampling center frequency of this round of sampling, and perform secondary frequency conversion processing (spectrum shifting) on ​​the received broadband signal according to the frequency deviation corresponding to each channel to obtain the narrowband signal of the detector corresponding to the center frequency of each channel in the corresponding channel. Finally, through parallel computing technologies such as multi-threading and Compute Unified Device Architecture (CUDA), the corresponding data callback function is called to send the narrowband signal of each channel to the corresponding detector through the corresponding channel, so that each detector can work concurrently based on the received narrowband signal to achieve optimal processing efficiency.

[0076] It should be noted that for each round of sampling, when the channelizer sends the sampling center frequency of the round of sampling to the wideband signal receiver, it can also send the target sampling minimum duration corresponding to the round of sampling to the wideband receiver, so that the wideband receiver collects the corresponding wideband signal based on the received sampling center frequency and the target sampling minimum duration. Among them, the target sampling minimum duration at this time is the longest sampling minimum duration in the registration request provided by the detector corresponding to the center frequency covered by the round of sampling.

[0077] S205: Determine the single sampling center frequency of the channelizer according to the channel list, and send the single sampling center frequency to the wideband receiver, so that the wideband receiver collects the corresponding wideband signal based on the single sampling center frequency.

[0078] In the specific process of executing step S205, the channelizer determines the highest center frequency and the lowest center frequency in the channel list, so as to determine the single sampling center frequency of the channelizer according to the determined highest center frequency and the lowest center frequency, and sends the single sampling center frequency to the wideband receiver, so that the wideband receiver collects the corresponding wideband signal based on the single sampling center frequency. At this time, the wideband signal collected by the wideband receiver can cover all channels in the channel list, and all channels in the channel list may correspond to multiple detectors, that is, the wideband signal collected by the wideband receiver can cover the signals required by multiple detectors, thereby solving the problem in the prior art that the detectors are designed for a specific single communication protocol and cannot be applied to drone signals of various communication protocols.

[0079] Optionally, the process of determining the single sampling center frequency of the channelizer according to the channel list can be specifically as follows: determining the highest center frequency and the lowest center frequency in the channel list; calculating the highest sampling frequency corresponding to the channel list according to the channel bandwidth of the detector corresponding to the highest center frequency and the highest center frequency, and calculating the lowest sampling frequency corresponding to the channel list according to the channel bandwidth of the detector corresponding to the lowest center frequency and the lowest center frequency; calculating half of the sum of the highest sampling frequency and the lowest sampling frequency to obtain the single sampling center frequency of the channelizer.

[0080] For example, the highest center frequency in the channel list is 2460Mhz, and the lowest center frequency is 2410Mhz. The channel bandwidth of the detector corresponding to the highest center frequency is 20Mhz, and the channel bandwidth of the detector corresponding to the lowest center frequency is 10Mhz. Therefore, the calculation method of the single sampling center frequency of the channelizer can be determined as: (highest sampling frequency (2460+20 / 2=2470) + lowest sampling frequency (2410-10 / 2=2405)) / 2=2437Mhz.

[0081] S206: Process the broadband signal sent by the broadband receiver according to the channel corresponding to each center frequency in the channel list to obtain the narrowband signal of the channel corresponding to each center frequency, and feed back the narrowband signal of the channel corresponding to each center frequency to the corresponding detector.

[0082] In the specific process of executing step S206, when the channelizer receives the broadband signal collected and sent by the broadband receiver based on the single-sampling center frequency, it can calculate the frequency deviation between the center frequency corresponding to each channel in the channel list and the single-sampling center frequency, and perform secondary frequency conversion processing (spectrum shifting) on ​​the received broadband signal according to the frequency deviation corresponding to each channel to obtain the narrowband signal of the detector corresponding to the center frequency of each channel in the corresponding channel. Finally, through multi-threading and parallel computing technologies such as CUDA, the corresponding data callback function is called to send the narrowband signal of each channel to the corresponding detector through the corresponding channel, so that each detector can work concurrently based on the received narrowband signal to achieve optimal processing efficiency.

[0083] It should be noted that when the channelizer sends the single sampling center frequency to the wideband signal receiver, it can also send the corresponding target sampling minimum duration to the wideband receiver, so that the wideband receiver can collect the corresponding wideband signal based on the received single sampling center frequency and the target sampling minimum duration. The target sampling minimum duration at this time is the longest sampling minimum duration in the registration request provided by the detector corresponding to each center frequency in the channel list.

[0084] The present application provides a multi-protocol wireless signal processing method, which receives a registration request sent by at least one detector through a channelizer; the registration request of the detector includes at least a channel list and a channel bandwidth, and the channel list includes at least one center frequency point; a channel list list is generated according to each of the center frequencies, and whether the channelizer meets the single signal acquisition condition is determined according to the channel list list and the maximum bandwidth of the broadband receiver; if the channelizer does not meet the single signal acquisition condition, the sampling center frequency point of each round of sampling is determined according to the channel list list, and at least one channel covered by each round of sampling is determined according to the sampling center frequency point of each round of sampling and the maximum bandwidth of the broadband receiver; for each round of sampling, the sampling center frequency point of the round of sampling can be sent to the broadband receiver, so that the broadband receiver receives the sampling center frequency point based on the received sampling center frequency point. The corresponding broadband signal is collected at the center frequency point. At this time, the broadband signal collected by the broadband receiver can cover all channels covered by this round of sampling, and all channels covered by this round of sampling can correspond to multiple detectors, that is, the broadband signal collected by the broadband receiver can cover the signals required by multiple detectors, thereby solving the problem in the prior art that the detectors are designed for a specific single communication protocol and cannot be applied to drone signals of various communication protocols; the broadband signal sent by the broadband receiver is processed according to each channel covered by this round of sampling to obtain the narrowband signal corresponding to each channel covered by this round of sampling, and the narrowband signal corresponding to each channel covered by this round of sampling is fed back to the corresponding detector at the same time, so that the detectors corresponding to each center frequency point can work concurrently based on the received narrowband signal to achieve the optimal processing efficiency.

[0085] In order to better understand the above content, the following examples are given below:

[0086] For example, the channelizer receives registration requests sent by detectors A, B, and C; wherein, the channel list in the registration request sent by detector A includes central frequencies such as 2410Mhz, 2420Mhz, 2430Mhz, and 2440Mhz, the channel bandwidth is 10Mhz, the input data sampling rate is 15Mhz, the minimum sampling duration is 20ms, and the data callback function is chan_data_procA(); the channel list in the registration request sent by detector B includes central frequencies such as 2440Mhz, 2450Mhz, 2460Mhz, and 2470Mhz, the channel bandwidth is 20Mhz, the input data sampling rate is 15Mhz, the minimum sampling duration is 20ms, and the data callback function is chan_data_procA(). The sampling rate is 30Mhz, and the minimum sampling duration is 30ms; the channel list in the registration request sent by detector C includes 915Mhz and 930Mhz, the channel bandwidth is 2Mhz, the input data sampling rate is 2Mhz, and the minimum sampling duration is 10ms; the center frequencies in the channel lists in the registration requests sent by detectors A, detector B and detector C are ordered from small to large to generate a channel list (915Mhz, 930Mhz, 2410Mhz, 2420Mhz, 2430Mhz, 2440Mhz, 2440Mhz, 2450Mhz, 2460Mhz, 2470Mhz).

[0087] Among the center frequencies in the channel list, the highest center frequency is 2460Mhz, the lowest center frequency is 915Mhz, the channel bandwidth of the detector corresponding to the highest center frequency is 20Mhz, and the channel bandwidth of the detector corresponding to the lowest center frequency is 2Mhz; therefore, it can be determined that the frequency band sampling range of the channel list can be calculated as follows: the highest sampling frequency (2460+20 / 2=2470) - the lowest sampling frequency (915-2 / 2=914) = 1556Mhz (frequency band sampling range); if the maximum bandwidth of the broadband receiver is 56Mhz, it can be determined that the frequency band sampling range of the channel list is greater than the maximum bandwidth of the broadband receiver, and therefore it can be determined that the broadband receiver cannot cover all the center frequencies in the channel list in a single acquisition, and thus it can be determined that the channelizer does not meet the single signal acquisition conditions.

[0088] From the channel list, it can be determined that the lowest center frequency is 915Mhz, and then the lower limit sampling frequency of the first round of sampling can be calculated as: 915 (lowest center frequency) - 2 / 2 (channel bandwidth) = 914Mhz, and the center frequency of the first round of sampling is calculated as 914 (lower limit sampling frequency) + 56 (maximum bandwidth) / 2 = 942. Based on the sampling center frequency (942Mhz) of the first round of sampling, half of the maximum bandwidth of the wideband receiver (28Mhz) is expanded upward and half of the maximum bandwidth of the wideband receiver (28Mhz) is expanded downward, respectively, and the sampling range of the first round of sampling is 914Mhz~970Mhz. According to the sampling range of the first round of sampling and the channel bandwidth of the detector corresponding to each center frequency in the channel list, it can be determined from the channel list that the center frequencies covered by the first round of sampling include 915Mhz and 930Mhz, and the channels covered by the first round of sampling are determined according to the center frequencies covered by the first round of sampling.

[0089] Eliminate the center frequencies covered by the first round of sampling from the channel list. At this time, it can be found that there are still center frequencies in the channel list. Continuing to determine the lowest center frequency from the channel list is 2410Mhz. The lower limit sampling frequency of the second round of sampling can be calculated as: 2410-10 / 2=2405Mhz, and the center frequency of the second round of sampling is calculated as 2405+56 / 2=2433. Based on the sampling center frequency of the second round of sampling (2433Mhz), half of the maximum bandwidth of the wideband receiver (28Mhz) is expanded upward. And downwardly expand half of the maximum bandwidth of the wideband receiver (28Mhz), and obtain the sampling range of the second round of sampling is 2405Mhz~2461Mhz, and then according to the sampling range of the second round of sampling and the channel bandwidth of the detector corresponding to each center frequency point in the channel list, it can be determined from the channel list that the center frequency points covered by the second round of sampling include 2410Mhz, 2420Mhz, 2430Mhz, 2440Mhz, 2440Mhz, and 2450Mhz, and the channels covered by the second round of sampling are determined according to the center frequency points covered by the second round of sampling.

[0090] Eliminate the center frequencies covered by the second round of sampling from the channel list. At this time, it can be found that there are still center frequencies in the channel list. Continue to determine the lowest center frequency from the channel list as 2460Mhz, and calculate the lower limit sampling frequency of the third round of sampling as: 2460-20 / 2=2450Mhz; if the maximum bandwidth of the bandwidth receiver is 56Mhz, the center frequency of the third round of sampling can be calculated as 2450+56 / 2=2478. Based on the sampling center frequency of the third round of sampling (2478Mhz), expand upwards respectively. The sampling range of the third round of sampling is 2450Mhz~2506Mhz, and then according to the sampling range of the third round of sampling and the channel bandwidth of the detector corresponding to each center frequency point in the channel list, it can be determined from the channel list that the center frequency points covered by the third round of sampling include 2460Mhz and 2470Mhz, and the channels covered by the third round of sampling are determined according to the center frequency points covered by the third round of sampling.

[0091] For each round of sampling, when the channelizer sends the sampling center frequency of the round of sampling to the wideband signal receiver, it can also send the target sampling minimum duration corresponding to the round of sampling to the wideband receiver, so that the wideband receiver collects the corresponding wideband signal based on the received sampling center frequency and the target sampling minimum duration. The target sampling minimum duration at this time is the longest sampling minimum duration in the registration request provided by the detector corresponding to the center frequency covered by the round of sampling.

[0092] When the channelizer receives the broadband signal collected and sent by the broadband receiver based on the sampling center frequency of this round of sampling and the target sampling minimum duration, it can calculate the frequency deviation between the center frequency corresponding to each channel covered by this round of sampling and the sampling center frequency of this round of sampling, and perform secondary frequency conversion processing (spectrum shifting) on ​​the received broadband signal according to the frequency deviation corresponding to each channel to obtain the narrowband signal of each channel. Finally, through multi-threading and parallel computing technologies such as CUDA, the corresponding data callback function is called to send the narrowband signal of each channel to the corresponding detector through the corresponding channel.
