In step S230, decision module 110_3 is based on average load situation and judging result determines access point 100_1
Transmission range.In one embodiment, the transmission range is for example preset as the first range, and decision module 110_3 can be based on
Average load situation and judging result decide whether that will transmit range expands as the second range, or maintain the first range.For
The details of step S230 is described in more detail, enumerates Fig. 3 separately below to be illustrated.
Fig. 3 is to implement the flow chart that the access point exemplified executes method for managing power supply according to Fig. 2.In the present embodiment,
The related description of the details of step S210 and S220 referring to figure 2., details are not described herein.In addition, the step S230 of Fig. 2 is more segmented
For the step S310~S316 and S331~S335 of Fig. 3.
After step S220, decision module 110_3 can judge whether the judging result indicates to hand in step s310
Parallel operation 200 is in first mode or the second system time of access point 100_1 belongs to the second preset time section.If exchanger
200 are not at first mode and the second system time of access point 100_1 is also not belonging to the second preset time section, then determine mould
Block 110_3 can proceed with step S311~S316.If exchanger 200 is in the second of first mode and/or access point 100_1
System time belongs to the second preset time section, then decision module 110_3 can proceed with step S331~S335.
In step S311, decision module 110_3 can setting access point 100_1 time interval be first time length.
Then, in step S312, decision module 110_3 can determine whether the transmission range of access point 100_1 is the first range.If
It is that in step S313, decision module 110_3 can determine whether the average load situation of access point 100_1 is lower than first threshold.
If so, the transmission range that decision module 110_3 can adjust access point 100 is that (it is greater than first to the second range in step S314
Range).Later, decision module 110_3 can return to step S210, be calculated again with controlling computing module 110_1 in time interval
Average load situation in (that is, first time length).
In one embodiment, the first threshold is, for example, the 50% of system load, but the present invention is not limited thereto.Herein
In the case of, when decision module 110_3 judges the average load situation of access point 100_1 lower than first threshold in step S313
When value, indicate the client within the scope of the transmission of current access point 100_1 quantity and/or access point 100_1 average load/
Utilization rate is lower.Therefore, it is the second model that decision module 110_3 can expand the transmission range of access point 100_1 in step S314
It encloses, to cover more clients, and then makes full use of the calculation resources of (fully exploit) access point 100_1.
On the other hand, if decision module 110_3 judges average load situation not less than first threshold in step S313
Value, indicate the client within the scope of the transmission of current access point 100_1 quantity and/or access point 100_1 average load/make
It is not too low with rate.Therefore, decision module 110_3 can directly return step S210, calculated again with controlling computing module 110_1
Average load situation in time interval.
In other embodiments, if decision module 110_3 judges the transmission range of access point 100_1 not in step S312
For the first range, decision module 110_3 can be performed whether step S315 is higher than with the average load situation for judging access point 100_1
Second threshold.If so, the transmission range that decision module 110_3 can adjust access point 100_1 is the first model in step S316
It encloses.Later, decision module 110_3 can return to step S210, calculate access point 100_1's again to control computing module 110_1
Average load situation.
In one embodiment, the second threshold is, for example, the 90% of system load, but the present invention is not limited thereto.Herein
In the case of, when decision module 110_3 judges that the average load situation of access point 100_1 is higher than second threshold in step S315
When value, indicate the client within the scope of the transmission of current access point 100_1 quantity and/or processing unit 120 average load/
Utilization rate has been approached fully loaded.Therefore, decision module 110_3 can reduce the transmission range of access point 100_1 in step S316 and be
First range to cover less client, and then mitigates the burden of access point 100_1.
On the other hand, if decision module 110_3 judges average load situation not higher than second threshold in step S315
Value, indicate the client within the scope of the transmission of current access point 100_1 quantity and/or processing unit 120 average load/make
It is not excessively high with rate.Therefore, decision module 110_3 can directly return step S210, calculated again with controlling computing module 110_1
Average load situation in time interval.
In other embodiments, if decision module 110_3 judges that exchanger 200 is in first mode and/or access point
The second system time of 100_1 belongs to the second preset time section, then when step S331 can be performed to set in decision module 110_3
Between section be less than first time length the second time span (such as 0.5 hour).That is, when exchanger 200 is in
When the second system time of first mode and/or access point 100_1 belong to the second preset time section (for example, quitting time),
Decision module 110_3 can shorten the observing time for calculating average load situation, more immediately according to average load situation
Adjustment transmission range.
Then, in step S332, decision module 110_3 can record covering of the access point 100_1 for multiple client
Situation.For example, all clients that the recordable transmission range instantly of decision module 110_3 can cover.Later,
In step S333, decision module 110_3 can determine whether the transmission range of access point 100_1 is the second range.
When decision module 110_3 judges that the transmission range of access point 100_1 is not or not second range, in step S334,
The transmission range that decision module 110_3 can adjust access point 100_1 is the second range.It is, when exchanger 200 is in first
When the second system time of mode and/or access point 100_1 belong to the second preset time section, due to the visitor of required service instantly
Family end may be less, and distribution is also sparse, therefore transmission range can be adjusted to biggish second model by decision module 110_3
It encloses, to cover more client.Later, decision module 110_3 can return to step S210, to control computing module 110_1 again
Average load situation of the secondary calculating in time interval (that is, second time span).
However, if decision module 110_3 judge in step S333 the transmission range of access point 100_1 for the second range,
After then covering situation to exchanger 200 of the step S335 to return access point 100_1 can be performed in decision module 110_3, determine
Module 110_3 can return to step S210, be calculated again in time interval with controlling computing module 110_1 (that is, the second time is long
Degree) in average load situation.
In short, the access point 100_1 of the embodiment of the present invention is not at first mode and access point in exchanger 200
When the second system time of 100_1 is not belonging to the second preset time section, access point 100_1 observable is flat in time interval
Equal load situation, and determine that the first range or the second range is used to transmit range as it accordingly.And access point 100_1 is being exchanged
When the second system time that device 200 is in first mode and/or access point 100_1 belongs to the second preset time section, access point
100_1 can diameter enforcement use the second range as its transmission range, to cover more client.That is, of the invention deposits
Take point 100_1 can be according to the execution pattern of exchanger 200 or system time and the average load of access point 100_1 itself
Situation reduces or expands transmission range adaptively to provide service to client.
Fig. 4 is that multiple access points that an implementation according to the present invention exemplifies use individually the first range as transmission range
To service the schematic diagram of multiple client respectively.In this example, it is assumed that n is that 4, exchanger 200 is not at first mode simultaneously
And the second system time of each access point 100_1~100_4 is not belonging to the second preset time section (that is, non-quitting time), and
The average load situation of each access point 100_1~100_4 is all higher than first threshold.Therefore, each access point 100_1~100_4 can
First range R1~R4 is used to transmit range as it, to cover client 1~14.
Referring to figure 5., Fig. 5 is that multiple access points that an implementation according to the present invention exemplifies use individually the second range to make
It is transmission range the schematic diagram that services multiple client respectively.In this example, it is assumed that exchanger 200 at this time is in the
The second system time of one mode and/or each access point 100_1~100_4 belong to the second preset time section, and client 2,
4,6,7,12,13 (that is, the clients indicated with S) are turned off and/or present off-line state.At this point, due to only remain client 1,
3,5,8~11,14 need to service, therefore each access point 100_1~100_4 can be used the second range R1 '~R4 ' as its transmission
Range, to cover negligible amounts and be distributed sparse client 1,3,5,8~11,14.
In one embodiment, in the case where access point 100_1~100_4 expands transmission range, it would be possible to which generation only needs
A part in access point 100_1~100_4 can cover the situation of client 1,3,5,8~11,14.At this point, the present invention mentions
Exchanger 200 out can be found out from access point 100_1~100_4 by method introduced below be enough to cover client 1,
3,5,8~11,14 the first access point, and then certain unwanted second access points in forbidden energy access point 100_1~100_4.
In this way, which exchanger 200 can make full use of the resource of the first access point, and the electric power for saving the second access point simultaneously disappears
Consumption.
Fig. 6 is the flow chart that the exchanger that an implementation according to the present invention exemplifies executes method for managing power supply.In this reality
It applies in example, the processing unit 230 of exchanger 200 can access judgment module 220_1 stored by storage element 220, switching module

In step S610, it is default that judgment module 220_1 judges whether the first system time of exchanger 200 belongs to first
Time interval.In the present embodiment, the first preset time section be, for example, general office quitting time or other by pipe
The time of reason person's sets itself, the present invention are limited not to this.
In step S620, when the first system time belonging to the first preset time section, switching module 220_2 is changeable
Exchanger 200 is first mode, and sends the first switching signal CS1 to access point 100_1~100_n of instruction first mode.
In step S630, collection module 220_3 collects each access point 100_1~100_n in response to the first switching signal
The covering situation for multiple client that CS1 is returned.In step S640, module 220_4 is found according to each access point
The covering situation of 100_1~100_n is found out from multiple access point 100_1~100_n is enough to service multiple client at least
One the first access point.In step S650, adjustment module 220_5 at least one in forbidden energy access point the after the preset lime
At least one second access point except one access point.
In order to which step S640~S650 is described in more detail, step S640~S650 is also subdivided into figure in detail by the present invention
