Detailed Description
For a more clear understanding of the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
It should be noted that the flow charts shown in the drawings are only exemplary and do not necessarily include all the contents and operations/steps, nor do they necessarily have to be executed in the order described. For example, some operations/steps may be decomposed, and some operations/steps may be combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.
The block diagrams shown in the figures are functional entities only and do not necessarily correspond to physically separate entities. I.e. these functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor means and/or microcontroller means.
Note that, the Beacon (Beacon): is the noun of the router side;
beacon Interval (Beacon Interval): the term "router" refers to a time interval between two beacons;
DTIM value: the term router refers to how many beacon intervals a multicast traffic is sent.
Listening Interval (Listen Interval): is the term WiFi device end, which refers to how many beacon intervals the WiFi device experiences between two awakes. A longer listening interval allows the WiFi device to turn off the transmitter longer, the longer the power is turned off, meaning that more power can be saved, thus significantly prolonging battery usage.
Wherein the two values of the listen interval value and the DTIM value are the same, the WiFi device tells the router this value by negotiation. The listening interval value and the DTIM value are both in units of beacon intervals, for example, 3 beacon interval times with a listening interval value of 3.
Generally speaking, a WiFi device sets a listening interval value before sleeping, and after the listening interval value is passed, the WiFi device must wake up to listen for data addressed to itself. Since the router buffers the data frame sent to the WiFi device in the sleep state, the buffering duration is greater than or equal to the listening interval value. If the WiFi device does not wake up to acquire the buffered data after the buffering duration, the router will directly discard the frames without further notification.
As shown in fig. 1, a first embodiment of the present invention discloses a method for reducing power consumption of a WiFi device, which is applied to the WiFi device, and includes the following steps:
s10: after the current router is connected, setting a current listening interval value according to the beacon interval value of the router;
s20: sending a request needing response to a preset server, entering a DTIM data receiving mode and timing;
s30: detecting whether DTIM data is received in the current listening interval time, and if so, taking the current listening interval value as a final listening interval value; if not, decreasing the current listening interval value.
If the DTIM data sent by the router is not received in the current listening interval time (the DTIM data is a certain number of Beacon packets sent by the router under the DTIM value), it indicates that the router does not cache a sufficient number of Beacon packets in the current listening interval time, because the router caches a sufficient number of Beacon packets to send, and therefore the DTIM value of the router should be decreased, that is, the listening interval value of the WiFi device should be decreased, so that the Beacon packets cached by the router can be received when the WiFi device wakes up.
Specifically, the setting the current listening interval value according to the beacon interval value of the router further comprises:
s00: and connecting the router to obtain the beacon interval value of the router. Generally speaking, the beacon interval value of a router is stable for a period of time after being set, so that the time difference between every two adjacent times of receiving beacons transmitted by the router can be recorded, the average value of all the time differences is calculated, and the average value is used as the beacon interval value of the router, which is the accurate beacon interval value of the current router, and is generally 100ms. It is to be understood that the beacon interval value is merely illustrated herein, and is not to be construed as limiting the value thereof.
As shown in fig. 2, a second embodiment of the present invention discloses a method for reducing power consumption of a WiFi device, which is applied to the WiFi device, and includes the steps described in the first embodiment.
Wherein, step S30 includes:
s301: detecting whether DTIM data is received in the current listening interval time, if so, executing S302; if not, executing S303;
s302: taking the current listening interval value as a final listening interval value;
s303: reducing the current listening interval value and returning to step S20, namely, sending a request for response to a preset server, entering a receiving DTIM data mode and timing, thereby repeatedly adjusting the listening interval value until the DTIM data is reduced to be received within the current listening interval time.
As shown in fig. 3, a third embodiment of the present invention discloses a method for reducing power consumption of a WiFi device, which is applied to the WiFi device, and includes the steps described in the first embodiment or the second embodiment.
Wherein the setting of the current listening interval value according to the beacon interval value of the router comprises:
s101-1: presetting a maximum value and a minimum value of a listening interval according to the beacon interval value. The maximum value is used for ensuring that the communication delay is within an acceptable range, and the minimum value is used for ensuring that the WiFi equipment and all routers meeting the WiFi energy-saving mode standard can normally work. The minimum allowed by the WiFi power saving mode standard is 0 and all routers can support, but the power consumption will be slightly increased to balance the power consumption according to the actual product power consumption requirement, for example, set to 3. The maximum value can be determined according to actual products, for example, the server issues an instruction to require the equipment to respond within a specified time, and the maximum value is obtained after the time is converted into a listening interval;
s102-1: after the router is currently connected, taking the maximum value as the current listening interval value.
And, said decreasing said current listening interval value comprises: decreasing the current listening interval value according to a step-by-step method until decreasing to the minimum value. For example, the current listening interval value is decreased in 1 step until the minimum value is decreased. It is to be understood that the process of reducing the listening interval value is merely illustrated herein and does not constitute a limitation on the adjustment logic thereof.
As shown in fig. 4, a fourth embodiment of the present invention discloses a method for reducing power consumption of a WiFi device, which is applied to the WiFi device, and includes the steps described in the first embodiment or the second embodiment.
Wherein the setting of the current listening interval value according to the beacon interval value of the router comprises:
s101-2: a maximum value and a minimum value of a listening interval are preset according to the beacon interval value. The maximum value is used for ensuring that the communication delay is within an acceptable range, and the minimum value is used for ensuring that the WiFi equipment and all routers meeting the WiFi energy-saving mode standard can normally work. The minimum allowed by the WiFi power saving mode standard is 0 and all routers can support it, but the power consumption will be slightly increased according to the actual product power consumption requirement to balance the power consumption, for example, set to 3. The maximum value can be determined according to actual products, for example, the server issues an instruction to require the equipment to respond within a specified time, and the maximum value is obtained after the time is converted into a listening interval;
s102-2: and after the router is connected currently, taking the maximum value and the minimum value as an upper limit value and a lower limit value during adjustment respectively, and taking the middle value of the upper limit value and the lower limit value as a current listening interval value.

taking the current listening interval value as a lower limit value;
judging whether the difference value between the upper limit value and the lower limit value is a second preset value, for example, the second preset value is 1, if not, taking the middle value between the upper limit value and the lower limit value as the latest current listening interval value, returning to execute the request of sending a response to a preset server, entering a DTIM data receiving mode and timing; if yes, the lower limit value is used as a final listening interval value.

For example, depending on the actual situation, such as the maximum value of 30, the minimum value of 2, a maximum of 20 times is possible according to the step method, and a maximum of 5 times is possible according to the dichotomy; if the maximum value is 10 and the minimum value is 2, the difference between the number of times of adjustment by the step method and the dichotomy is not so large.

If the DTIM data is not received in the current listening interval time, it indicates that the router does not cache a sufficient number of Beacon packets in the current listening interval time, and because the router does not transmit until the router caches the sufficient number of Beacon packets, the DTIM value should be decreased, that is, the listening interval value should be decreased, so that the Beacon packets cached by the router can be received when the WiFi device wakes up.
Specifically, the WiFi device further includes:
