Embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, the present invention is made below in conjunction with accompanying drawing into
One step it is described in detail, it is clear that the described embodiment only a part of embodiment of the present invention, rather than whole implementation
Example.Based on the embodiment in the present invention, what those of ordinary skill in the art were obtained under the premise of creative work is not made
All other embodiment, belongs to the scope of protection of the invention.
The invention discloses a kind of method of the maximum connection number of terminals of record AP history based on flash, implement such as Fig. 1
It is shown, including：
S200 monitors AP access terminal situation, after having new terminal to access the AP, obtains the current connection of the AP
Number of terminals；
S300 judges whether the current connection number of terminals of the AP is more than connection number threshold value, if so, into next step, it is no
Then, return to step S200；
S400 by the connection number threshold value be updated to former connection number threshold value and default step value and, and by the AP ought
Preceding connection number of terminals write-in flash is stored.
In the present embodiment, there is provided default step value, when AP current connection number of terminals is more than connection number threshold value, can incite somebody to action
Connection number threshold value be updated to former connection number threshold value and default step value and, and by the current connection number of terminals write-in of the AP
Flash is stored.Connection number threshold value in the present embodiment can change, and be not unalterable.Specifically, such as when
Preceding connection number threshold value is 65, and default step value is 8；If the current connection number of terminals of AP is got as 66, it is clear that be more than
Current connection number threshold value, therefore, connection number threshold value is updated to：65+8=73, flash threshold values are then updated in flash
For 73, and record AP connection number of terminals 66.Then proceed to monitor AP access terminal number, if there is new terminal access again,
The current connection number of terminals for getting the AP is 70, it is clear that current connection number of terminals 70 is less than the connection number threshold value after renewal
73, therefore, threshold value will not be updated in flash and writes AP maximum connection number of terminals 73.So just reduce to flash's
Write operation, while AP maximum connection number of terminals is also obtained, the connection number threshold value after the renewal that we record can be considered as AP's
Maximum connection number of terminals, more excellent, we can also take the AP of newest storage connection number of terminals as AP history most Dalian
Connect number of terminals.Certainly, this AP not necessarily accurate AP of the maximum connection number of terminals of history maximum history connection terminal
Number, actual AP maximum history connection number of terminals typically connect number of terminals with being connected in the AP of state-of-the-art record history maximum
Between number threshold value, such as previous examples, it is between 66-73.The setting of general step-length influences whether the maximum connection of history eventually
The accurate of number is held, still, we can be by reasonably setting a step-length so that can accurately record AP history most
Big connection number of terminals, and can reduce the loss to flash.
Preferably, also include：S010 is after AP starts, the write-in connection number threshold value in flash.
After AP starts completely, connection number threshold value can be initially write during meeting in flash.This connection number threshold value is just
Can be as the subsequently reference standard compared with currently connection number of terminals, certainly, when the current connection number of terminals of acquisition is more than
When initializing the connection number threshold value of write-in, the connection number threshold value will update.
Preferably, on the basis of any of the above-described embodiment, increase step S100 becomes new embodiment, specifically, this
Invention another embodiment as shown in Fig. 2 including：
S010 is after AP starts, the write-in connection number threshold value in flash；
S100 reads the maximum history value of the connection number of terminals of the AP from flash, judges the connection number of terminals
Maximum history value whether be more than it is described connection number threshold value, if so, then using the maximum history value of the connection number of terminals of the AP as
The connection number threshold value；
S200 monitors AP access terminal situation, after having new terminal to access the AP, obtains the current connection of the AP
Number of terminals；
S300 judges whether the current connection number of terminals of the AP is more than connection number threshold value, if so, into next step, it is no
Then, return to step S200；
S400 by the connection number threshold value be updated to former connection number threshold value and default step value and, and by the AP ought
Preceding connection number of terminals write-in flash is stored.
Specifically, after such as AP starts, initialization write-in flash connection numbers threshold value 60, the AP is then read from flash
Connection number of terminals history maximum, if the maximum value of the connection number of terminals that records before is 65, then just this is connected
The maximum history value 65 of number of terminals is as connection number threshold value, that is to say, that connection number threshold value is changed to 65 by the 60 of initialization write-in
.Then AP access terminal situation is monitored again, after having new terminal to access the AP, obtains the number of terminals that the AP is currently connected,
Then more current connection number of terminals is with being connected the size of number threshold value, if being currently accessed number of terminals less than or equal to 65 so
Continue to monitor AP terminal access situation, if being currently accessed number of terminals more than 65, for example get the current of the AP
It is 66 to connect number of terminals, and the current number of terminals 66 that connects is more than connection number threshold value 65, then just connection number threshold value is updated, it is false
If default step value is 10, then the connection number threshold value after renewal is 75, records AP connection number of terminals 66；Be then back to after
Continuous monitoring AP access terminal situation, as long as follow-up AP access terminal number is not more than 75, need not all trigger flash again writes behaviour
Make, without being recorded again in flash.
Preferably, step S100 includes in above-described embodiment：
S110 judges the connection number of terminals of the AP whether is stored with the flash, if into step S130, otherwise
Into step S120；
It is 0 that S120, which sets the maximum history value of the connection number of terminals of the AP,；
S130 reads the maximum history value of the connection number of terminals of the AP from flash；
S140 judges whether the maximum history value of the connection number of terminals is more than the connection number threshold value, if so, entering step
Rapid S150；
S150 is using the maximum history value of the connection number of terminals of the AP as the connection number threshold value.
In the present embodiment, if after initialization write-in flash connection number threshold values, do not read in the flash of the AP and remember
The connection number of terminals of record, then the maximum history value of the connection number of terminals of the AP is just set to 0.
A kind of another embodiment of the method for the maximum connection number of terminals of record AP history based on flash of the present invention, it is above-mentioned
Step value is preset described in any embodiment and includes default first step value and default second step value, default first step-length
Value is less than default second step value；Idiographic flow as shown in figure 3, including：
S200 monitors AP access terminal situation, after having new terminal to access the AP, obtains the current connection of the AP
Number of terminals；
S300 judges whether the current connection number of terminals of the AP is more than connection number threshold value, if so, into next step, it is no
Then, return to step S200；
S410 judges whether the connection number threshold value is more than default reference threshold, if so, then entering step S420, otherwise
Into step S430；
S420 by the connection number threshold value be updated to former connection number threshold value and default first step value and；
S430 by the connection number threshold value be updated to former connection number threshold value and default second step value and；
S440 is stored the current connection number of terminals write-in flash of the AP.
Specifically, such as default first step value is 5, and default second step value is 10；It is 55 to connect number threshold value, in advance
If reference threshold be 70；If getting AP currently connects number of terminals as 56, it is clear that more than connection number threshold value 55, and connects number
Threshold value 55 is less than default reference threshold 70, and therefore, connection number threshold value is updated to：The original connection default second steps of number threshold value 55+
Long value 10=65, that is, connect number threshold value and become 65；AP current connection number of terminals 56 is write into flash again to be stored；With
Continue to monitor AP terminal situation afterwards, if there are other new terminals to access again, it is 60 to get current connection number of terminals, due to working as
Preceding connection number of terminals 60 is less than connection number threshold value 65, therefore, will not trigger flash write operations, return and continue monitoring terminal situation,
If the terminal that keeps accesses the AP, and it is 66 to get current connection number of terminals, it is clear that current connection number of terminals 66 is more than
Number threshold value 65 is connected, therefore, connection number threshold value renewal step is stepped into again, threshold is referred to less than default due to connecting number threshold value 65
Value 70, therefore, continue to take default second step value 10, that is, the connection number threshold value after updating is 65+10=75；Then by AP's
Current connection number of terminals 66 writes flash storages, then proceedes to monitor AP terminal access situation, for example monitors that AP's is current
Access terminal increases 76, it can be seen that current connection number terminal 76 is more than connection number threshold value 75, therefore, connects number threshold
Value needs have updated again, now, because connection number threshold value 75 is more than default reference threshold 70, therefore, the step-length now chosen
It is worth for default first step value, that is, the connection number threshold value after updating is：75+5=80, then by AP current connection number of terminals
76, which also write flash, is stored.It can be seen, connect before number threshold value is 55, AP connection number of terminals be less than or
Equal to 55 all without triggering write operation, when AP connection number of terminals is more than 55, write operation can be just triggered, by AP's
Connection number threshold value is updated；After AP connection number threshold value is 65, only AP connection number of terminals, which is more than 65, can just trigger
New write operation, AP connection number threshold value is updated；Equally, after renewal, when AP connection number of terminals is less than or equal to 75
When, all without triggering flash write operation, only when AP connection number of terminals is more than 75, renewal can be just triggered again, this
When, because AP connection number threshold value 75 is more than default reference threshold 70, therefore, the step-length of selection is the default first default step
Long value 5, therefore the connection number threshold value after updating is 75+5=80.By the way that there is provided a default reference threshold, number will be connected
Threshold value chooses different step-lengths according to the difference of comparative result compared with default reference threshold.We are also, it is understood that more arrive
Below, numeral is bigger, then may more easily go wrong, and our AP to record maximum connection number of terminals also requires more accurate,
Therefore, we can equally set the step value more set to below smaller, allow the maximum connection number of terminals of history of record also to get over
Close to the actual AP maximum connection number of terminals of history, so as to reduce flash write operations, flash damages and record AP are reduced
Maximum connection number of terminals the degree of accuracy between reach a preferably balance.
Another embodiment of the inventive method, as shown in figure 4, including：
(1) after AP starts completely, initialization writes flash threshold values as 60；
(2) AP connection terminal maximum history values are read from flash, might as well be set to max (may be without value, if being pressed without value at 0
Reason), if more than 60, write falsh threshold values and be arranged to max, the variable is set to threshold；
(3) terminal access is waited；
(4) number of terminals of current AP connections is obtained, num might as well be set to after new terminal access AP every time；
(5) if num is more than threshold value threshold, by threshold value with being newly threshold=threshold+10, and will
In num values write-in flash.For example present threshold value is that 60, num values are 61, then threshold value is updated to 70, and num values (i.e. 61) are write
Enter in flash；
(6) go to step (3).
Hardware of the Flash as store function, although after AP power-off, data will not lose in flash, read and write meeting repeatedly
To flash damages (our product flash read and write the order of magnitude that number is probably ten thousand times), if reaching the flash read-write upper limits,
Flash will be scrapped.Read-write flash repeatedly is thus reduced to be necessary.In the present embodiment, behaviour is write by setting step-length to reduce
Make, for example this write-in flash value is 60, then can just be triggered when connecting number of terminals and being more than 70 and write flash operations next time.This
Sample sets the number of writing that can be reduced to flash by step-length, and then postpones the flash life-spans.
Based on identical technical concept, the invention also discloses a kind of maximum connection of record AP history based on flash is whole
The device of number is held, the device can use any of the above-described embodiment of the method, specifically, as shown in figure 5, the present invention is based on flash's

In said apparatus embodiment, connection number threshold value is an order of magnitude, and the connection number threshold value of renewal can be considered as record
The maximum connection number of terminals of AP history, it is more excellent, can be using newest storage AP current connection number of terminals as AP history maximum
Number of terminals is connected, although both of which is not the maximum connection number of terminals of AP history (the actual AP history maximum of physical record
Number of terminals is connected between the AP connection number of terminals and current connection number threshold value of newest storage), but set in default step value
In the case of rational, and the AP maximum connection number of terminals of history can be accurately recorded, so as to can be more
Accurately the maximum connection number of terminals of record AP history, and can reduce the write operation to flash, extend flash service life.
Preferably, said write module 30, is additionally operable to after AP starts, the write-in connection number in flash memory modules 40
Threshold value.After AP starts, initialization write-in flash connection number threshold values, the connection number threshold value at this moment write is that system is set, phase
When in default value, startup can all write the connection number threshold value of this acquiescence set to AP every time.
