Embodiment
Because WLAN webmaster is not yet communicated with PON webmaster, cannot the present situation of transmission of information, the present invention proposes a kind of method for controlling power supply of wireless access point AP, based on the statistical analysis to real network ruuning situation, design device and the treatment mechanism thereof of a set of each AP complete machine timing shutoff, thus a large amount of AP that solution hot spot coverage idle period AP continuous firing causes leave unused and the problem of the wasting of resources, increase network utilization, reduce the power consumption of wlan system.As shown in Figure 3, the program needs to arrange power supply control apparatus in a switch, is used for independently opening or shutoff operation each lower port hanging AP, and concrete, the method comprises the steps:
S301, obtains the changed power information of described AP in each described continuous time interval and changes in flow rate information.
Arrange because the present invention needs to utilize the power in interval each continuous time and flow information to carry out periodicity to the power supply of follow up date, therefore before this step, multiple length can be divided into interval for identical continuous time according to current date, in this, as the adjustment cycle of follow-up power supply, this continuous time interval quantity and length can adjust flexibly according to actual needs.In addition.For the consideration for technical dates, also can obtain the specific date that user selects, and unified power supply mark is set for the interval each continuous time of described specific date.
Concrete, this step is divided into following three flow processs to carry out:
(1) according to the sample frequency preset, periodicity collection is carried out to the instantaneous delivery of the port of the described AP of lower extension and instantaneous power;
(2) sampled result in each described continuous time interval is carried out matching respectively, obtain the power curve corresponding with interval each described continuous time and flow curve, and determine the rate of change of described power curve and described flow curve respectively;
(3) using the rate of change of described power curve and correspondence thereof as described changed power information, using the rate of change of described flow curve and correspondence thereof as described changes in flow rate information.
S302, according to described changed power information, described changes in flow rate information and default power versus flow associating determination strategy, judge whether described AP has user's access features in each described continuous time in interval, and according to judged result be each described continuous time interval arrange power supply mark.
The present invention by the access behavior of flow information and power information comprehensive descision user, such as following three concrete schemes:
(1) if the flow curve in current time interval levels off to cyclic variation, and described power curve is all the time lower than the access power threshold value preset, then determine that described current time interval does not have user's access features;
(2) if the flow curve in current time interval does not level off to cyclic variation, and described power curve is lower than predetermined power threshold value, then determine that described current time interval has user's access features;
(3) if described power curve and described flow curve are all the time higher than the access power threshold value preset, then determine that described current time interval has user's access features.
In addition, identifying operation is easy in order to make power supply control apparatus, power supply mark is specifically set to power-on flag and power-off mark by the present invention, correspondingly, if current time interval has user's access features, be then that power-on flag is distributed in described current time interval, described power-on flag is used to indicate described power supply control apparatus and opens; If current time interval does not have user's access features, be then that power-off mark is distributed in described current time interval, described power-off mark is used to indicate described power supply control apparatus and closes.
S303, according to described current date, each described continuous time, interval and power supply mark generates the power supply control strategy of described AP.
In this step, by determining the time tagmeme of described current date in this week, generate described time tagmeme and each described continuous time is interval and the mapping table between identifying of powering, using described mapping table as described power supply control strategy.Afterwards, the power supply control strategy of also AP described in regular update can be stored.
S304, is sent to described power supply control apparatus by described power supply control strategy, with the port making described power supply control apparatus open according to described power supply control policy independence or close for the described AP of lower extension in described switch.
In order to set forth technological thought of the present invention further, the ONU/PoE switch inside structure schematic diagram after existing improvement shown in composition graphs 4, is described technical scheme of the present invention.Because switch architecture is complicated, and improvement of the present invention is power supply control aspect, only sets forth realizing the lower relevant improvement part hanging AP power supply control therefore.As shown in Figure 4, of the present inventionly add the timing of ONU end mouth in former ONU/PoE switch inside and turn off control module, for unlatching, the shut-in time of each output port of control ONU, thus the timing power supply realized hanging AP under ONU controls.
With reference to figure 5, what turn off controller and remote control service device thereof for the timing of ONU end mouth realizes schematic diagram, and it mainly comprises 8 subelements: collecting unit, memory cell, display unit, decision unit, calendar cells, policy unit, performance element, backup units.Concrete handling process is as follows:
(1) for holiday no collection time (supposing that this WLAN deployment scene is no user festivals or holidays): by the calendar cells of remote control service device, by the current year calendar information import policy unit, Lookup protocol period festivals or holidays ONU all power output port close.
(2) for office hours on working day (supposing that this WLAN deployment scene has the tidal effect that daytime is busy, evening is idle): with the Δ t time (being generally the integral multiple of Beacon frame period) for the sampling period, periodically gather instantaneous delivery and the instantaneous power of each output port of ONU, and collection result is input to memory cell preserves, then have a 3600/ Δ t sampled point in 1 hour.
(3) data in memory cell to remote control service device, first enter into display unit by network delivery, show instantaneous delivery and the change curve of instantaneous power in 1 hour of each output port of ONU respectively, by a 3600/ Δ t sampled point matching.Rate of change in statistic curve 1 hour, is input to decision unit.
(4) whether decision unit has user to access according to ONU port in following rule judgment 1 hour:
A) flow curve is cyclic variation trend, and power curve is lower than threshold value Pidle-none: illustrate that AP that this port is corresponding is in the idle condition of no user access, only have the heartbeat packet between AC, AP;
B) flow curve has no obvious cyclic variation trend and lower than threshold value Tidle-any, power curve is lower than threshold value Pidle-any: illustrate that the AP that this port is corresponding has user-association but non-authentication, or have subscription authentication but without business, only have the system message between AP and STA;
C) no matter flow curve or power curve all maintain high value (can see that ONU/PoE switch ports themselves indicator light does not stop flicker): illustrate that the AP that this port is corresponding is having user to carry out WLAN business, continuous transmitting control information and data message between AP and STA.
(5) above-mentioned situation a, this AP no user access in thinking this 1 hour, situation b, c think has user to access.No user is accessed the period to use ● represent, has user to access the period and represent with zero, by that analogy, for week age, user as shown in table 1 can be formed and access situation statistical mask:
Table 1AP user accesses situation statistical mask/mono-week
As can be seen from Table 1, by the calendar function of step 1, ONU end confession electricity directly can be closed on Saturday, Sunday; By the flow of step 2 ~ 4, power collecting and judgement, workaday AP busy-idle condition can mark in units of 1 hour.Therefore, table 1 defines the busy collection of illustrative plates of AP, and the time period of grey can close ONU end confession electricity, realizes the economize on electricity of super not busy AP.
