Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

At present, the traditional point-to-point access mode in microwave communication cannot meet the requirement of a complex application scene, so that technicians use the point-to-multipoint access mode, namely a master station needs to be capable of receiving access of a plurality of slave stations at the same time, and the requirement of the complex application scene is met. At present, when a plurality of slave stations access a master station, radio frequency quality parameters of all access frequency points allowing the slave stations to work need to be acquired simultaneously, and the sequence of the slave stations adopting the frequency points to access the master station is determined according to the radio frequency quality parameters corresponding to the frequency points respectively, so that the plurality of slave stations can be automatically accessed to the master station without configuration for communication. However, in the prior art, under the condition that the working frequency band is complex, a plurality of bandwidths which allow the slave station to work and have different sizes exist, each bandwidth corresponds to a plurality of frequency points, and because a large number of radio frequency quality parameters of the access frequency points need to be acquired simultaneously, and the frequency point access sequence is determined according to the radio frequency quality parameters, the efficiency of the slave station accessing the master station is reduced, and the efficiency of microwave communication is low.

At present, in the prior art, the frequency points corresponding to the same bandwidth cannot be adopted according to the access sequence of the same bandwidth, the master station is tried to be accessed, and when the frequency points corresponding to the current bandwidth are failed to be accessed into the master station, the frequency points corresponding to the bandwidth smaller than the current bandwidth are further tried to be adopted, and the master station is tried to be accessed, so that the slave station can be rapidly accessed into the master station, and the microwave communication efficiency is improved.

Therefore, the present disclosure provides an access method of a wireless communication device, by obtaining multiple sets of access frequency parameters corresponding to a target slave station, where the access frequency parameters include a bandwidth and multiple frequency points corresponding to the bandwidth; determining at least one group of first access frequency parameters from the plurality of groups of access frequency parameters, wherein the bandwidth in the first access frequency parameters is the maximum working bandwidth of the target slave station; attempting to access the primary station using at least one set of first access frequency parameters; if the attempt of accessing the master station by adopting at least one group of first access frequency parameters fails, attempting to access the master station according to at least one group of second access frequency parameters; and the at least one group of second access frequency parameters are other access frequency parameters except the at least one group of first access frequency parameters in the multiple groups of access frequency parameters. Therefore, under the condition that the working bandwidth is complex, the target slave station can automatically and preferentially acquire the first access frequency parameter to attempt to access the master station, after the first access frequency parameter fails to attempt to access the master station, multiple groups of second access frequency parameters are automatically acquired to attempt to access the master station, and traversing search is conducted on the multiple groups of second access frequency parameters, so that the working frequency parameters of the master station are determined, the slave station can be rapidly accessed to the master station, and the microwave communication efficiency is improved.

Fig. 1 is a flowchart illustrating an embodiment of an access method of a wireless communication device according to an embodiment of the present disclosure, and as shown in fig. 1, the access method of the wireless communication device may include the following steps:

s01: and acquiring a plurality of groups of access frequency parameters corresponding to the target slave station.

The access frequency parameters comprise a plurality of different bandwidths allowing the slave station to work and a plurality of frequency points corresponding to each bandwidth. The target slave station is any one of a plurality of slave stations corresponding to the main station, the multiple groups of access frequency parameters refer to that the target slave station cannot access the main station according to initial access frequency parameters adopted when the target slave station successfully accesses the main station at the last time due to the fact that the working bandwidth and frequency points are possibly switched when the current main station works, or due to downtime, the target slave station needs to acquire the multiple groups of access frequency parameters of the access main station, the multiple groups of access frequency parameters comprise access frequency parameters enabling the target slave station to access the main station, the target slave station conducts traversal search on the multiple groups of access frequency parameters, and therefore the access frequency parameters enabling the target slave station to access the main station are determined, and the target slave station is accessed to the main station according to the access frequency parameters. The multiple sets of access frequency parameters may be frequency points working on the same bandwidth, or frequency points working on different bandwidths, for example, the frequency points may be frequency points with a bandwidth of 160MHz and different frequency points, specifically, such as {160MHz, ahz }, {160MHz, a +20MHz }, {160MHz, a +40MHz }, {160MHz, a +60MHz }; but may be different bandwidths, such as 160MHz and 80MHz, specifically {160MHz, ahmhz }, {160MHz, a +20MHz }, {160MHz, a +40MHz }, {160MHz, a +60MHz }, {80MHz, bMHz }, {80MHz, b +80MHz }, without being limited thereto, and the disclosure is not limited thereto.

Specifically, when the target slave station is started or restarted, the target slave station cannot access the master station according to the initial access frequency parameter when the target slave station successfully accesses the master station last time due to the change of the working bandwidth and frequency point of the master station, and the target slave station acquires multiple corresponding sets of access frequency parameters.

It should be noted that, when operating, the master station can only operate on one bandwidth of the preset limited bandwidths, for example, the operating bandwidth of the microwave communication system includes 160MHz, 80MHz, 40MHz, and 20MHz, and therefore, the master station can only operate on one bandwidth of four bandwidths of 160MHz, 80MHz, 40MHz, and 20MHz, but is not limited thereto, and the disclosure is not limited in particular.

S02: at least one set of first access frequency parameters is determined from a plurality of sets of access frequency parameters.

The bandwidth in the first access frequency parameter is the maximum working bandwidth of the target slave station, the first access frequency parameter further comprises a first access frequency point, and the first access frequency point is a central frequency point of the maximum working bandwidth. Specifically, for example, the master station can only operate in one of four bandwidths of 160MHz, 80MHz, 40MHz, and 20MHz, the maximum operating bandwidth is 160MHz, that is, the operating bandwidth of the first access frequency parameter is 160MHz, and the first access frequency parameter includes a plurality of first access frequency points corresponding to the maximum operating bandwidth of 160MHz and the maximum operating bandwidth of 160MHz, and specifically may include {160MHz, ahhz }, {160MHz, a +160MHz }, {160MHz, a +320MHz }, {160MHz, a +480MHz }.

S03: an attempt is made to access the primary station using at least one set of first access frequency parameters.

Specifically, when the target slave station fails to access the master station by using the initial access frequency parameter, multiple sets of first access frequency parameters in multiple sets of access frequency parameters corresponding to the target slave station are obtained, traversal is performed in the multiple sets of first access frequency parameters, and the master station is tried to be accessed by adopting traversal of the multiple sets of first access frequency parameters.

Illustratively, the initial access frequency parameter may be {80MHz, 20MHz }, when access to the master station fails by using the initial access frequency parameter, and when the frequency point operation range allowed by the target slave station is ahmhz to bhmhz, a group of bandwidth configurations supported by the target slave station are 160MHz, 80MHz, 40MHz, and 20MHz …, according to the bandwidth configurations, it is determined that the maximum operation bandwidth supported by the target slave station is 160MHz, that is, the bandwidth size in the first access frequency parameter is 160MHz, the frequency point operation ranges from ahmhz to bhmhz are divided according to 160MHz, a plurality of operation bandwidths with the bandwidth size of 160MHz are obtained, and a plurality of frequency points with the operation bandwidth of 160MHz, for example, a +80MHz, a +240MHz … …, and so on, but the last frequency point should be less than or equal to frequency point b, traversal is performed on the plurality of groups of first access frequency parameters, and access to the master station is attempted to use the plurality of groups of first access frequency parameters, but is not limited thereto, and the present disclosure is not particularly limited.

S023: and if the attempt to access the master station by adopting the at least one group of first access frequency parameters fails, attempting to access the master station according to the at least one group of second access frequency parameters.

Wherein the at least one set of second access frequency parameter is other than the at least one set of first access frequency parameter in the multiple sets of access frequency parameters, a bandwidth in the second access frequency parameter is smaller than a bandwidth in the first access frequency parameter, and for a bandwidth of two adjacent orders, the bandwidth of the higher order is 2 times the bandwidth of the lower order, for example, the set of bandwidths supported by the target secondary station is configured to be 160MHz, 80MHz, 40MHz, and 20MHz …, that is, the bandwidth of the higher order in the two adjacent orders is 2 times the bandwidth of the lower order, but the disclosure is not limited thereto.

Specifically, when the target slave station starts or restarts, and when access to the master station fails by using multiple sets of first access frequency parameters, the target slave station traverses from multiple sets of second access frequency parameters, and tries to access to the master station by using multiple sets of second access frequency parameters.

Illustratively, a set of bandwidths supported by the slave station is configured as 160MHz, 80MHz, 40MHz and 20MHz …, when all access frequency points corresponding to the maximum bandwidth bit 160MHz in the first access frequency parameter fail to access the master station, the bandwidth in the second access frequency parameter is determined to be 80MHz according to the order of the bandwidth from the high order to the low order within the frequency point working range allowed by the slave station, and the corresponding frequency point can be {80MHz, bMHz }, {80MHz, b +80MHz }, {80MHz, b +160MHz }, for example, the target slave station selects an access frequency parameter which does not attempt to access the master station, such as {80MHz, bMHz }, and attempts to access the master station with {80MHz, bMHz }, sends a request for access to the master station, when a response for access is not received by the master station, determines that the target slave station fails to access the master station, and further selects an access frequency parameter which does not attempt to access the master station, such as {80MHz } from the second access frequency parameter, b +80MHz, and the target slave station tries to access the master station again by {80MHz, b +80MHz } until the target slave station succeeds in accessing the master station, but the disclosure is not limited thereto.

In the embodiment, multiple groups of access frequency parameters corresponding to a target slave station are obtained, wherein the access frequency parameters comprise bandwidths and multiple frequency points corresponding to the bandwidths; determining at least one group of first access frequency parameters from the plurality of groups of access frequency parameters, wherein the bandwidth in the first access frequency parameters is the maximum working bandwidth of the target slave station; attempting to access the primary station using at least one set of first access frequency parameters; if the attempt of accessing the master station by adopting at least one group of first access frequency parameters fails, attempting to access the master station according to at least one group of second access frequency parameters; and the at least one group of second access frequency parameters are other access frequency parameters except the at least one group of first access frequency parameters in the multiple groups of access frequency parameters. Therefore, under the condition that the working bandwidth is complex, the target slave station can automatically and preferentially acquire the first access frequency parameter to attempt to access the master station, after the first access frequency parameter fails to attempt to access the master station, multiple groups of second access frequency parameters are automatically acquired to attempt to access the master station, and traversing search is conducted on the multiple groups of second access frequency parameters, so that the working frequency parameters of the master station are determined, the slave station can be rapidly accessed to the master station, and the microwave communication efficiency is improved.

S032: and adopting at least one first frequency point to try to access the master station.

On the basis of the above embodiments, in some embodiments of the present disclosure, as shown in fig. 3, one possible implementation manner of S032 is as follows:

s30: and judging whether at least one first frequency point has a first frequency point which is not tried to be accessed.

S31: when it is determined that the first frequency points which are not tried to be accessed exist in the at least one first frequency point, selecting one first frequency point which is not tried to be accessed from the at least one first frequency point.

S34: if the access of the frequency point which is not tried to access to the master station fails, whether other first frequency points which are not tried to access exist in at least one first frequency point is judged.

Illustratively, the at least one first frequency point is, for example, {160MHz, ahz }, {160MHz, a +160MHz }, {160MHz, a +320MHz }, which is a central frequency point corresponding to the maximum operating bandwidth in the first access frequency parameter, determining whether there is a frequency point which is not attempted to access the primary station in the at least one first frequency point, when it is determined that there is a frequency point which is not attempted to access in the at least one first frequency point, the target secondary station sends a request for access to the primary station from the first frequency point which is not attempted to access, for example, {160MHz, ahz }, and when the target secondary station attempts to access the primary station using {160MHz, ahz }, the target secondary station fails to access the primary station again, and when an access response is not received by the primary station, determining whether there are other frequency points which are not attempted to access, when the target slave station exists, the target slave station tries to access the master station again at the first frequency point such as 160MHz, a +160MHz and 160MHz, a +320MHz, and selects a first frequency point such as 160MHz, a +160MHz, at which time, when the target slave station still fails to access the master station by using 160MHz, a +160MHz, and so on, the traversal is continued until the target slave station successfully accesses the master station, but the disclosure is not limited thereto.

On the basis of the above embodiments, in some embodiments of the present disclosure, as shown in fig. 3, the method further includes:

s36: and when the frequency points which are not tried to access the main station do not exist in the at least one first frequency point, the target slave station tries to access the main station by adopting the at least one second frequency point.

Specifically, when it is determined that no frequency point which is not tried to access the master station exists in the at least one first frequency point, it is determined that the attempt to access the master station fails according to the at least one first frequency point, and at this time, the target slave station acquires the at least one second frequency point and attempts to access the master station by using the second frequency point which is not tried to access the master station.

S033: if the attempt of accessing the master station by adopting at least one first frequency point fails, acquiring the size of the radio frequency quality parameter corresponding to the at least one first frequency point, and determining the maximum working bandwidth in the first access frequency parameter and the access combination priority of the first frequency point according to the size of the radio frequency quality parameter corresponding to the at least one first frequency point;

the radio frequency quality parameters are that when the target slave station fails to access the master station according to the maximum working bandwidth in the first access frequency parameters and the corresponding first frequency point, the target slave station can collect the maximum working bandwidth and the radio frequency quality parameters corresponding to the first frequency point, sort the maximum working bandwidth supported by the target slave station according to the radio frequency quality parameters, and obtain the optimal access frequency parameters of the target slave station accessing the master station according to the sorting result, so that the target slave station can be ensured to preferentially determine the optimal access frequency parameters in multiple groups of access frequency parameters.

For example, when the target slave station fails to access the master station by using the maximum operating bandwidth and the first frequency point, such as {160MHz, b +80MHz }, the radio frequency module of the target slave station collects radio frequency quality parameters corresponding to the maximum operating bandwidth and the first frequency point, such as {160MHz, b +80MHz }, but the disclosure is not limited thereto.

Specifically, when the target slave station fails to access the master station by adopting the first frequency point, the size of the radio frequency quality parameter corresponding to at least one first frequency point is obtained, and the access sequence of the first access frequency parameter supported by the target slave station is determined according to the size of the radio frequency quality parameter.

The second frequency point is the other frequency points except the first frequency point in at least one group of first access frequency parameters.

Illustratively, when the maximum operating bandwidth supported by the target secondary station is 160MHz, and the first frequency point is a +80MHz, the at least one second frequency point in the maximum operating bandwidth may be, for example, but not limited to {160MHz, ahhz }, {160MHz, a +20MHz }, {160MHz, a +40MHz }, and {160MHz, a +60MHz }.

Specifically, when the target slave station fails to access the master station by adopting the first frequency point, a first access queue sequence of the maximum working bandwidth and a second frequency point combination except the central frequency point is determined according to the access combination priority corresponding to the first access frequency parameter, and the target slave station tries to access the master station by adopting the maximum bandwidth and the second frequency point combination in sequence according to the first access queue sequence.

Specifically, when it is determined that no frequency point which is not tried to access the master station exists in at least one second frequency point, a second access queue sequence of a bandwidth and frequency point combination of a second access frequency parameter is determined according to an access combination priority corresponding to the first access frequency parameter, and further, according to the second access queue sequence, the target slave station sequentially traverses the second access frequency parameter in the second access queue sequence, and tries to access the master station by using the second access frequency parameter until the target slave station accesses the master station, or all the second access frequency parameters in the second access queue sequence are traversed.

In this embodiment, when the target slave station fails to access the master station by using the multiple first frequency points in the first access frequency parameter, the radio frequency quality parameters corresponding to the first frequency points are obtained, based on the size of the radio frequency quality parameters, the access combination priority of the first access frequency parameters is determined, based on the access combination priority, in the presence of a second frequency point which is not attempted to be accessed, the first access queue sequence of the second frequency points is determined, the multiple second frequency points are sequentially and automatically traversed, and the second frequency point is adopted to attempt to access the master station, so that the target slave station is ensured to access the master station by using the optimal access frequency parameter, the optimal networking under the complex bandwidth is realized, and the efficiency of microwave communication is further improved.

S011: and if the target slave station fails to attempt to access the master station by adopting the initial access frequency parameters, acquiring a plurality of groups of access frequency parameters corresponding to the target slave station.

The initial access parameter refers to an access parameter adopted by the slave station when the slave station successfully accesses the master station last time, the initial access parameter includes a bandwidth and a frequency point when the slave station successfully accesses the master station, the frequency point is a frequency point within the bandwidth, and the initial access parameter may be, for example, but is not limited thereto, and the disclosure is not particularly limited.

Specifically, after the target slave station is started or restarted, if the target slave station determines that the master station is successfully accessed last time, the target slave station acquires initial access parameters adopted when the master station is successfully accessed last time from the storage unit, when the target slave station adopts the initial access parameters to access the master station, an access request is sent to the master station, an access response returned by the master station is not obtained, and when it is determined that the target slave station fails to adopt the current initial access parameters to access the master station, a plurality of groups of access frequency parameters corresponding to the target slave station are acquired.

Therefore, in this embodiment, when the target slave station cannot access the master station according to the initial access frequency parameter of the last successful access to the master station, the target slave station can automatically acquire multiple corresponding sets of access frequency parameters, and under the condition that the working bandwidth is complex, the target slave station tries to access the master station to multiple sets of access frequencies, so that the efficiency of microwave communication is improved.

Another embodiment of an access method of a wireless communication device, a flowchart of which is shown in fig. 7, is applied to a microwave communication system including a primary station and a plurality of secondary stations, and when one of the plurality of secondary stations needs to access to the primary station, the access method is as follows.

S75: judging whether a second frequency point exists or not; if the second frequency point exists, switching to the step S76, and if the second frequency point does not exist, switching to the step S78;

s76: and when the second frequency point is determined to exist, entering a same-order bandwidth pre-access step, and trying to access the master station by the target slave station by adopting the combination of the maximum working bandwidth and the second frequency point according to the sequence of the first access queue.

S77: and judging whether the master station can be successfully accessed by adopting the maximum working bandwidth and the second frequency point.

S78: and when the second frequency point is determined to be absent or the main station cannot be successfully accessed by adopting the maximum working bandwidth and the second frequency point, entering a reduced bandwidth pre-access step, and according to the second access queue sequence, the target slave station tries to access the main station by adopting a second access frequency parameter.

S79: and judging whether the master station can be successfully accessed by adopting the second access frequency parameter.

S710: and returning to the initial access step when the master station cannot be successfully accessed by adopting the second access frequency parameter is determined.

S711: and the target slave station successfully accesses the master station and records the current access frequency parameter.

Specifically, firstly, a fast access step is adopted, where fast access is implemented in an initial access phase, and the target slave station attempts to access the master station by using a bandwidth and frequency point combination (i.e. an initial access frequency parameter) of the last successful access master station. Assuming that the bandwidth and frequency point of the master station do not change frequently, after the slave station starts or restarts, the slave station determines that the master station has been accessed successfully last time, and then tries to access the master station which can be accessed last time by preferentially using the combination of the bandwidth and frequency point which is accessed successfully last time, which is the fastest access mode. And if the access to the master station fails by adopting the initial access frequency parameters, entering the next step. Under certain conditions, if the main station switches bandwidth frequency points, or the main station is down, or the target slave station is accessed for the first time, the quick access step may fail, and the next step of initial access is performed.

And an initial access step, wherein if the target slave station fails to access the master station by adopting a quick access method, a plurality of groups of access frequency parameters corresponding to the target slave station are obtained, at least one group of first access frequency parameters are determined from the plurality of groups of access frequency parameters, and the master station is tried to be accessed by adopting the first access frequency parameters. The bandwidth used by the first access frequency parameter in the initial access step is the maximum working bandwidth supported by the device (the target slave station and/or the master station), for example, the bandwidth configuration range supported by the target slave station and/or the master station is 160MHz, 80MHz, 40MHz, and 20MHz … …, and then 160MHz is used as the bandwidth initially accessed by the device; the used frequency point is a first frequency point, the first frequency point which is initially accessed is a central frequency point which is not interfered mutually under the maximum working bandwidth, if a configurable starting frequency point a is added under the bandwidth of 160MHz, and an ending frequency point b is added, a +80MHz and a +240MHz … … can be selected as the central frequency points, and so on, but the last frequency point is less than or equal to the frequency point b. After the first frequency point of the first access frequency parameter is selected, the maximum working bandwidth and the first frequency point combination are put into a pre-access queue one by one, and the master station is tried to be accessed by the first access frequency parameter of the maximum working bandwidth and the first frequency point combination in sequence. If a certain combination of the maximum working bandwidth and the first frequency point combination is successfully accessed into the master station, the initial access step is finished, and the successfully accessed maximum working bandwidth and the first frequency point combination are stored so that the target slave station can be rapidly accessed into the master station for use next time. If any combination of the maximum working bandwidth and the first frequency point combination fails to access the master station, namely the first access frequency parameters in the traversal pre-access queue fail to access the master station, the initial access step fails, and the next step needs to be turned to.

In the initial access step, after a first frequency point of a first access frequency parameter is selected, a maximum working bandwidth + first frequency point combination is placed in a pre-access queue, the first access frequency parameter of the maximum working bandwidth + first frequency point combination is tried to be accessed to a main station in sequence, meanwhile, Received Signal Strength Indication (Received Signal Strength Indication, RSSI) and Signal to Noise Ratio (SNR) when each group of the maximum working bandwidth + first frequency point combination is tried to be accessed to the main station are collected, and the RSSI + data combination collected when the first access frequency parameter is tried to be accessed is stored in a Signal Strength analysis queue. And under the condition that any combination of the maximum working bandwidth and the first frequency point combination fails to be accessed to the main station, performing bandwidth and frequency point calculation (radio frequency parameter calculation), specifically, extracting all RSSI + SNR data combinations in a signal strength analysis queue, and sequencing each combination of the maximum working bandwidth and the first frequency point combination correspondingly according to the sequence of the RSSI to obtain the access combination priority of the maximum working bandwidth and the first frequency point combination. Preferably, in the case of considering the environmental noise, according to the weighting relationship between RSSI and SNR: and sequencing each corresponding combination in the maximum working bandwidth + first frequency point combination from large to small by RSSI + SNR, so as to obtain the access combination priority of the maximum working bandwidth + first frequency point combination.

According to the sequencing rule, the strength of RSSI and the influence of SNR are considered, wherein b is an influence factor; when b <1, the signal strength is more emphasized, and when b >1, the ambient signal-to-noise ratio is more emphasized. In practical use, when the RSSI is strong, the influence of the RSSI may be prioritized, and when the RSSI is weak, the influence of the SNR should be prioritized. In particular, switching between the two may be achieved by setting a threshold. Preferably, the impact factor b is associated with SNR-RSSI (noise floor), that is, b is (SNR-RSSI) × c, when noise increases, the impact factor b increases and SNR weight increases, when noise decreases, the impact factor b decreases and RSSI weight increases, in the above formula, c is a constant factor and is derived from an empirical value, which is not a design point of the present technical solution, and is obtained by combining with a conventional technique of signal-to-noise calculation.

And a same-order bandwidth pre-access step, namely judging whether a second frequency point exists in the maximum working bandwidth or not when the access combination priority of the maximum working bandwidth plus the first frequency point combination is obtained, wherein the second frequency point is the other frequency points except the first frequency point in the first access frequency parameter. If the second frequency point exists, acquiring a first access queue sequence of the maximum working bandwidth and the second frequency point combination based on the access combination priority; and according to the sequence of the first access queue, the combination of the maximum working bandwidth and the second frequency point is adopted in sequence to try to access the master station. Specifically, the same-order bandwidth pre-access needs to be satisfied, for example, if a frequency point (other frequency points except for the central frequency point) which is not pre-accessed exists under the order bandwidth, for example, the optimal combination of radio frequency parameter calculation is {160MHz, a +80MHz }, a +80MHz is used as the central frequency point in the initial access step, and other frequency points which are not tried to be pre-accessed exist in the frequency spectrum in which 160MHz is used as the interval, and if the 160 MHz-allowed planned frequency points include a, a +20MHz, a +40MHz, a +60MHz, a +80MHz, and … …, a +20MHz, a +40MHz, and a +60MHz are frequency points which meet the requirements, that is, the second frequency point, then the same-order bandwidth domain traversal method can be used for pre-access. And adopting the same-order bandwidth pre-access, and adding the combination of other non-pre-access frequency points (second frequency points) and the maximum working bandwidth under the order bandwidth into the pre-access queue according to the sequence of the first access queue, for example, adding {160MHz, a }, {160MHz, a +20MHz }, {160MHz, a +40MHz }, and {160MHz, a +60MHz } into the pre-access queue.

In the same-order bandwidth pre-access step, when the combination of the maximum working bandwidth and the second frequency point is added into a pre-access queue according to a first access queue sequence, the pre-access sequence of the combination of the maximum working bandwidth and the second frequency point in the pre-access queue, namely the first access queue sequence, is determined based on the access combination priority sequence of the maximum working bandwidth and the first frequency point combination, the target slave station selects the combination of the maximum working bandwidth and the second frequency point according to the first access queue sequence to try to access the master station in sequence, if a certain combination of the maximum working bandwidth and the second frequency point combination is successfully accessed to the master station, the same-order bandwidth access step is ended, and the successfully accessed maximum working bandwidth and the second frequency point combination are stored so that the target slave station can be rapidly accessed to the master station for the next time. If any combination of the maximum working bandwidth and the second frequency point combination fails to access the master station, namely the first access frequency parameters in the traversal pre-access queue fail to access the master station, the same-order bandwidth pre-access step fails, and the next step needs to be performed.

A step of reducing bandwidth pre-access, wherein if the target slave station fails to traverse the first access frequency parameter and tries to access the master station, the target slave station tries to access the master station according to the second access frequency parameter; the second access frequency parameter is the other access frequency parameters except the first access frequency parameter in the multiple groups of access frequency parameters of the target slave station. Wherein the bandwidth in the second access frequency parameter is less than the maximum operating bandwidth; attempting to access the primary station according to the second access frequency parameter, specifically including: acquiring a second access queue sequence of the bandwidth and frequency point combination of a second access frequency parameter based on the maximum working bandwidth + the access combination priority of the first frequency point; and according to the second access queue sequence, the target slave station tries to access the master station by adopting the second access frequency parameters in sequence until the target slave station accesses the master station or all the second access frequency parameters in the second access queue sequence are traversed. The step of reducing bandwidth pre-access is carried out under the condition that the pre-access step and the same-order bandwidth pre-access step fail to access the main station, or when the same-order bandwidth pre-access is not satisfied, the step of reducing bandwidth pre-access is used. The bandwidth reduction calculation method is to reduce the bandwidth by one order, and take the frequency point of the low-order bandwidth in the interval of the current-order bandwidth, which is allowed to be planned, as a central frequency point, for example, the optimal combination of radio frequency parameter calculation is a {160MHz, a +80MHz } combination, and through the bandwidth reduction calculation, take the bandwidth as 80MHz, and assume that 80MHz is in the interval of the 160MHz width with a +80MHz as the center and the frequency points allowed to be planned are two frequency points of b and b +80MHz, the obtained combinations are {80MHz, b } and {80MHz, b +80MHz }, and add the two obtained combinations into the pre-access queue according to the second access queue sequence. It should be noted that there are only 2 bandwidth-frequency point combinations obtained by the bandwidth reduction calculation method using one group of bandwidth-frequency point combinations.

In the same-order bandwidth pre-access step and the reduced-order bandwidth pre-access step, a first access queue sequence and a second access queue sequence are correspondingly adopted respectively, and specifically, the first access queue sequence and the second access queue sequence are both based on the maximum working bandwidth plus the access combination priority of the first frequency point. Specifically, for example, if 4 combinations of maximum operating bandwidths-first frequency points of 160MHz are tried to be accessed in the initial access step and all access fails, 4 sets of RSSI-SNR information in the queue are analyzed, and through the bandwidth and frequency point calculation step, the 4 sets of combinations are ordered and arranged to obtain access combination priorities, where the access combination priorities are regions 2, 3, 1, and 4; assuming that there are other 3 sets of maximum working bandwidth-second frequency point combinations allowed to be accessed in each 160MHz interval, 12 sets of pre-access combinations will be obtained through the same-order bandwidth pre-access step. The order of the first access queue of the 12 pre-access combinations is: 2a, 2b, 2c, 3a, 3b, 3c, 1a, 1b, 1c, 4a, 4b, 4 c. If the 12 groups of combinations are traversed and the master station cannot be accessed, the bandwidth reduction pre-access step is continued, 8 groups of 80MHz pre-access combinations are obtained, and the pre-access sequence (second access queue sequence) of the 8 groups of combinations is 21, 22, 31, 32, 11, 12, 41 and 42, wherein the first number represents which group of 160MHz combinations the combination belongs to, and the second letter represents the sequence number of the combination in two frequency domains of which 160MHz is decomposed into 80 MHz. After completing the pre-access of 21 and 22 sets of second access frequency parameters, two sets of RSSI-SNR combinations are obtained, and 4 sets of lower-order bandwidth-frequency point combinations of 40MHz are obtained through calculation, at this time, the 4 sets of combinations are added into the pre-access queue in sequence, the combination sequence in the pre-access queue is changed into 211, 212, 221, 222, 31, 32, 11, 12, 41 and 42, and so on, so that the pre-access queue is ensured to try all combinations of the best RSSI-SNR packets preferentially, and try the next best RSSI-SNR combinations. It should be noted that when the calculated combinations are added to the pre-access queue in sequence, the queue head is enqueued, that is, when the combination is taken out from the pre-access queue next time, the combination is taken out first; this ensures that all combinations of RSSI and SNR optimum regions are traversed first.

In the step of pre-accessing the reduced-order bandwidth, when the bandwidth is reduced to the lowest-order bandwidth, the obtained combination of the bandwidth and the frequency point still fails to be pre-accessed, which generally does not happen; however, if this happens, it means that the master station does not allow the target slave station to access (perhaps for other reasons such as the master station setting a white list or the master station having saturated access), at which point the target slave station does not perform any further bandwidth reduction calculations, but continues to fetch subsequent combination attempts from the pre-processing queue, at which point the 31, 32 combination will be fetched and subsequent iterations will be performed, with the iterative process being similar to that before.

When all possible combinations of the pre-access queues try to access and fail, it indicates that no suitable primary station can access, and at this time, it is necessary to return to the initial detection process.

In addition, according to another embodiment of the present disclosure, when the target slave station sets a fixed bandwidth access, if the fixed bandwidth is not the bandwidth in the initial access step, that is, the fixed bandwidth is not the maximum operating bandwidth, the initial access step does not initiate access of the combination of the maximum operating bandwidth and the first frequency point, and only RSSI-SNR data of the combination of the maximum operating bandwidth and the first frequency point is collected; and after the initial access step (here, since access is not initiated, it can be regarded as only the initial detection step) is completed, directly performing a bandwidth reduction calculation method to directly jump down to the set fixed bandwidth, for example, the initial detection bandwidth is 160MHz, 4 groups of detection bandwidth-frequency point combinations are total, the fixed bandwidth is set to 40MHz, and after the initial detection is completed, obtaining 4 × 4 — 16 groups of bandwidth-frequency point combinations of 40MHz by using the bandwidth reduction calculation method. And directly adopting the combination of fixed bandwidth and frequency point to try to access the master station.

According to the embodiment, the slave station has strong fault-tolerant capability, and can be accessed into the master station most optimally in the link fault recovery process.
