Accompanying drawing explanation
Fig. 1 is the flow chart of embodiments of the invention.
Embodiment
Illustrate preferred embodiment of the present invention according to Fig. 1 below.
The signal of Wireless LAN router (WIFI) is launched can be divided into two parts, part is the broadcast packet for carrying out Radio Broadcasting Agreements propagation, the data of this part are externally launched by fixed time interval, do not have the wireless device carrying out transfer of data with WIFI router can be known the information of router by broadcast packet, but these wireless devices can't carry out being connected with WIFI router and the transmission of data, therefore the transmitting power for broadcast packet is launched by maximum power all the time, the coverage of wireless router can not be affected, Part II is really for the data of transfer of data, the transfer of data of this part accounts for most ratios in the process of whole wireless transmission, only have wireless device and WIFI router to set up complete wireless connections simultaneously and can carry out wireless transfer of data, when having multiple stage wireless device and WIFI router sets up wireless connections, according to the agreement of 802.11, in the process setting up wireless connections, both will carry out transfer of data, at this moment WIFI router is by the power monitoring apparatus of WIFI router interior, detect the emissive porwer of the signal of the wireless device being in diverse location, the distance of each wireless device and WIFI router is obtained according to emissive porwer, thus determine the maximum distance of the wireless device carrying out transfer of data with WIFI router, determine the intensity of the transmitting power required for WIFI router according to this maximum distance simultaneously, then the transmission power intensity for WIFI router adjusts, finally realize the self-adjusting function of power.
As shown in Figure 1, be a preferred embodiment of the present invention, this embodiment provides a kind of Wireless LAN router power consumption control method, comprises following steps:
Whether step S1, WIFI router detection have wireless device and WIFI router to set up wireless connections, if had, carry out step S2;
Power monitoring apparatus in step S2, WIFI router detects all received power spectrum density (RSSI) of wireless device in data transmission procedure setting up wireless connections with WIFI router;
Step S3, WIFI router calculate the distance value of each wireless device and WIFI router according to the received power spectrum density obtained;
Step S4, WIFI router determine the optimal transmit power intensity of WIFI router according to distance value farthest;
The transmission power intensity of WIFI router is adjusted to the optimal transmit power intensity determined in step S4 by the power closed loop controller in step S5, WIFI router.
In described step S1, whether WIFI router detection has wireless device and WIFI router to set up wireless connections comprises two aspects: an aspect, being when setting up wireless connections without any wireless device and WIFI router, detecting and whether having wireless device and WIFI router to set up wireless connections; Whether another aspect is when having wireless device and WIFI router to set up wireless connections, detect and have new wireless device and WIFI router to set up wireless connections.
In described step S3, received power spectrum density and distance value are inversely, distance is far away, the intensity of received power spectrum density is lower, or, received power spectrum density and distance value proportional, distance is far away, the intensity of received power spectrum density is higher, and (computing formula of concrete distance value is different and different according to the model of the WIFI router adopted, there are positive slope and backslash rate two kinds of modes calculated under normal circumstances, also directly can pass through the register read distance value in WIFI router).
