Fig. 2 is a kind of structural representation of the frequency selecting device of the bluetooth equipment in the embodiment of the present invention.

Specific embodiment

In the prior art, when AFH methods are performed, generally by RSSI come detection cycle interference signal Intensity, choose the less frequency of interference value by the signal strength values that are calculated and be used as working frequency points. However, when interference assessment is carried out to frequency according to RSSI, not in view of interference the characteristics of and make Pointedly assess.There are many roads with band interference under complex environment, such as around bluetooth equipment By device or other jamming equipments, the frequency of selection not necessarily disturbs less frequency.Meanwhile, it is existing With the presence of the certain inaccuracy of RRSI methods.To sum up, the work that existing AFH methods are selected Frequency still suffers from the larger possibility of interference value.

In embodiments of the present invention, when the data that opposite equip. transmission is failed to successfully receive on frequency n Bao Shi, judges the poor-performing of frequency n, may there is larger interference, therefore by the excellent of frequency n First level reduction.When working frequency points are chosen, it is higher than certain rank that priority is chosen from bluetooth frequency list Frequency carry out data transmission, eliminate and be disturbed the larger frequency of influence, such that it is able to select interference It is worth less frequency as working frequency points.

It is understandable to enable above-mentioned purpose of the invention, feature and beneficial effect to become apparent, with reference to Accompanying drawing is described in detail to specific embodiment of the invention.

The embodiment of the invention provides a kind of frequency choosing method of bluetooth equipment, reference picture 1, below by way of Specific steps are described in detail.

Step S101, on all frequencies in bluetooth frequency list, packet is sent to opposite equip..

In specific implementation, bluetooth equipment in the course of the work, co-exists in 79 working frequency points, 79 works The frequency for making frequency is followed successively by 2402MHz~2480MHz, two neighboring frequency at intervals of 1MHz.When Detect interference on some frequencies than it is more serious when, these can be avoided by AFH methods and disturbed more Serious frequency, selection interference is relatively light, namely better performances frequency.

Bluetooth equipment after data is activation is completed in a working frequency points, is jumped in the course of work Another working frequency points proceeds data is activation.The transmission order of working frequency points is pseudorandom, bluetooth Equipment can carry out data is activation and the reception of 1600 times each second on 79 frequencies, the hair per secondary data The duration sent and receive is 625 μ s.In embodiments of the present invention, can first by 79 working frequency points It is built into a bluetooth frequency list, bluetooth equipment selects the frequency to carry out data hair in bluetooth frequency list Send and receive.

In actual applications, opposite equip. can refer to the equipment for receiving packet.Opposite equip. is being received After the packet sent to current Bluetooth equipment, response corresponding with packet is fed back to current Bluetooth equipment Packet.Current Bluetooth equipment can be master slave relation with the relation of opposite equip., or point-to-point Peer-to-peer.

Step S102, the priority to the frequency in the bluetooth frequency list is adjusted.

In specific implementation, in bluetooth frequency list, can include that frequency and frequency are corresponding preferential Level information.The priority of different frequent points can be with identical, it is also possible to different.In init state, bluetooth is frequently 79 frequencies can be included in point list, the initial priority of each frequency is identical.

The priority of bluetooth frequency list intermediate-frequeney point is adjustable.In embodiments of the present invention, can basis Judge whether the reply data bag that opposite equip. sends is received on a certain frequency, to the preferential of frequency Level is adjusted.Priority to frequency is adjusted, and can be the priority for improving frequency, it is also possible to It is the priority for reducing frequency.

For example, when the reply data bag that opposite equip. transmission is not received on frequency n, or cannot be just When really parsing the reply data bag received on frequency n, then can be determined that and connect not successfully on frequency n Receive the reply data bag of opposite equip. transmission.Now, judge the poor-performing of frequency n, can reduce The priority of frequency n.

In embodiments of the present invention, when frequency n is persistently subject to more serious interference, on frequency n May cannot repeatedly be successfully received reply data bag.Often detected on frequency n and once connect not successfully Reply data bag is received, then by the priority reduction of frequency n once.When repeatedly failed on frequency n When receiving reply data bag, the priority of frequency n is constantly reduced.When the priority reduction of frequency n During to default priority level G2, it is possible to determine that frequency n has currently been not suitable for carrying out data transmission, because This can remove frequency n from bluetooth frequency list.Now, the frequency points in the list of bluetooth frequency Less than 79.Default priority level G2 < G1.

After frequency n is removed from bluetooth frequency list, the frequency quantity in bluetooth frequency list is reduced, The time for traveling through a bluetooth frequency list is also accordingly reduced.

Understand in actual applications, the interference major part that bluetooth equipment is subject to is present with bandwidth-version. For example, the interference of common router is the interference of 20MHz bandwidth.Therefore, received when on a frequency The interference arrived than it is more serious when, then the frequency adjacent with the frequency values of this frequency probably there is also More serious interference.

In embodiments of the present invention, for the more serious frequency that preferably avoids interference, by frequency n When being removed from bluetooth frequency list, can will be adjacent with the frequency values of frequency n with bluetooth frequency list The priority of at least two frequencies accordingly turn down.

For example, the frequency values of frequency n are 2450MHz, removed from bluetooth frequency list by frequency n When, by frequency values for the frequency and frequency values of 2451MHz are the priority drop of the frequency of 2449MHz It is low.Can also be the frequency of 2451MHz by frequency values, the frequency of the frequency of 2452MHz, 2449MHz Point and 2448MHz frequency priority reduction, and frequency values for 2451MHz frequency and The frequency of 2449MHz priority reduction amplitude can be more than frequency values for 2452MHz frequency and The priority reduction amplitude of the frequency of 2448MHz.

In embodiments of the present invention, if being successfully received the reply data of opposite equip. transmission on frequency m Bao Shi, then can be determined that the better performances of frequency m, can improve the priority of frequency m.If in frequency The upper continuous several times of m can be successfully received the reply data bag of opposite equip. transmission, and due to interference Major part is present with bandwidth-version, when the interference of frequency m is smaller, the frequency values phase with frequency m The interference that at least two adjacent frequencies are subject to is likely to smaller, can now improve the frequency values with frequency m The priority of at least two adjacent frequencies.

For example, the frequency values of frequency m are 2460MHz, opposite equip. transmission is successfully received for continuous 5 times Reply data bag.Therefore, it can frequency values as the frequency and frequency values of 2461MHz are The priority of the frequency of 2459MHz is improved.Can also by frequency values for 2461MHz frequency, The priority of the frequency of the frequency of 2462MHz, the frequency of 2459MHz and 2458MHz is improved, and Frequency values can be more than for the priority increase rate of the frequency of the frequency and 2459MHz of 2461MHz Frequency values are the priority increase rate of the frequency of the frequency and 2458MHz of 2462MHz.

In actual applications, some frequency may can't be constantly subjected to more serious interference, may Only interference in certain time period is than more serious, and interference is smaller in other times section.For example, t1~t2It is that 2450MHz is in running order with the router of frequency with frequency values to have one in time period, and t2~t3The router is in off-mode in time period.That is, in t1~t2In time period, frequency values For the frequency of 2450MHz be subject to it is more serious disturb, and in t2~t3In time period, the interference being subject to compared with It is small.

Therefore, after some frequency is removed from bluetooth frequency list, when certain condition is met, The frequency can also be added in bluetooth frequency list again.

In embodiments of the present invention, from the foregoing it can be that because interference major part is deposited with bandwidth-version , therefore, when there is more serious interference on a frequency, then inclined with this frequency Interference present on frequency of the difference more than 10MHz may be smaller.By frequency n from bluetooth frequency list After middle removal, can detect with the deviation of the frequency values of frequency n more than whether there is in the range of 10MHz Frequency y, frequency y are the frequency for having been removed from bluetooth frequency list before this.When there is frequency y When, then frequency y is added to bluetooth frequency list, and frequency y priority be set to it is default preferential Rank G3, and G2 < G3 < G1.

For example, when in frequency values to disturb larger on the frequency of 2450MHz, then it is considered that frequency values For the interference of the frequency in the range of 2402MHz~2440MHz, 2460MHz~2480MHz is smaller.If inspection Measure in bluetooth frequency list in the absence of frequency values for 2411MHz frequency y when, then be by frequency values The frequency y of 2411MHz is added in bluetooth frequency list, and the priority of frequency y is set to preferentially Rank G3.

In embodiments of the present invention, by the preferential of at least two frequencies adjacent with the frequency values of frequency m When level is improved, it is possible to there is the frequency z adjacent with the frequency values of frequency m not in bluetooth frequency list Scene, i.e. before frequency z from bluetooth frequency list remove.At this point it is possible to frequency z is added again To in bluetooth frequency list, and the priority of frequency z is set to default priority level G4, and G2 < G4 < G1.

For example, being sent to be successfully received opposite equip. on the frequency of 2460MHz for continuous 5 times in frequency values Reply data bag, and frequency values for 2461MHz frequency z not in bluetooth frequency list.Now, Frequency z can be added in bluetooth frequency list, and the priority of frequency z is set to priority level G4。

Step S103, in the bluetooth frequency list, it is higher than default priority level G1 to choose priority Frequency as working frequency points.

In specific implementation, when carrying out data transmission, in bluetooth frequency list, can only choose excellent Frequency of the first level higher than default priority level G1 is used as working frequency points.Remaining priority is less than priority The other G1 and frequency higher than priority level G2 can examine frequency as needing checking rather than carry out data biography It is defeated.

In the prior art, Bluetooth device operation frequency surrounding interferers are generally detected by calculating RSSI Intensity, but when the environment residing for bluetooth equipment is complex, the less frequencies of RSSI for selecting On interference may be larger.

And in the embodiment of the present invention, when the data that opposite equip. transmission is failed to successfully receive on frequency n Bao Shi, judges the poor-performing of frequency n, it is understood that there may be larger interference, therefore by the preferential of frequency n Level is reduced.When working frequency points are chosen, priority is chosen from bluetooth frequency list higher than certain rank Frequency carries out data transmission, and eliminates and is disturbed the larger frequency of influence, such that it is able to select interference value Less frequency is used as working frequency points.
