The low-power-consumption network intelligent device needs to support the function of remote awakening, and the main technical scheme is that the intelligent device and the server are kept alive regularly. Because the NAT aging times configured by different routers are different, a general method is to select a smaller keep-alive interval to ensure compatibility with all routers, and the smaller the keep-alive interval is, the larger the average power consumption is, so that the standby time of the low-power-consumption network intelligent device is shorter.
Therefore, we propose a low power consumption device sleep keep-alive system and method to solve the above problems.
Disclosure of Invention
The invention aims to find the NAT aging time close to the maximum between an intelligent device and a keep-alive server by adopting a dynamic detection mechanism, and adjust the keep-alive interval in real time so as to achieve the average power consumption close to the optimum and improve the standby time of the intelligent device, and provides a low-power-consumption device dormancy keep-alive system and a method.
In order to achieve the purpose, the invention adopts the following technical scheme:

the keep-alive server is used for keeping alive the communication between the low-power-consumption intelligent equipment and the keep-alive server;
the detection server is used for detecting the keep-alive time interval of the low-power consumption intelligent device channel.
A low-power consumption device sleep keep-alive method comprises the following steps:
step one, the device initiates connection with a keep-alive server at a conservative initial keep-alive interval tk, and the keep-alive server responds to a connection request;
step two, the device initiates connection with the detection server by adding an increment delta to the initial keep-alive interval tk, and simultaneously locally starts a timer tk + delta +2 to wait for initiating a detection packet of the detection server;
step three, after receiving the detection request, the detection server delays tk + delta to initiate a detection response packet, and if the equipment receives the detection response packet, the equipment immediately sends a detection confirmation packet;
step four, after the detection server receives the detection confirmation packet, the keep-alive server is informed to update the keep-alive interval of the equipment to be tk + delta;
step five, when the equipment keeps alive next time, the keep-alive server informs the use of a new keep-alive interval;
step six, if the device does not receive the detection response packet after the time out of tk + delta +2 after the step two, the device adjusts delta to delta/2 to reinitiate the detection request, and if the device does not receive the detection response packet after the time out of tk + delta +2, the delta is halved again until the delta is less than 3, and the detection is quitted;
and step seven, if the detection request packet is received before tk + delta is overtime in the step six, repeating the step three.
Preferably, in the fifth step, after receiving the new keep-alive interval, the device adjusts the keep-alive interval and initiates a new probe request, where tk + delta.
The technical scheme provided by the embodiment of the invention can have the following beneficial effects:
compared with the prior art, the invention has the advantages that the average of the bottom current of the current low-power chip is 100-250uA, the power consumption peak value of the transmitted protection data reaches 700mA, the average current of the chip adopting the 30s keep-alive interval is 1.6-2mA, and the average current of the chip adopting the 60s keep-alive interval is 0.8-1.2 mA. By adopting a dynamic detection mechanism, the protection interval can be adjusted to 300s under most conditions, the protection interval under partial environment is 600s, and the average power consumption is 250 plus 500 uA.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-2, a low-power device sleep keep-alive system includes a low-power intelligent device, a keep-alive server and a detection server;
the keep-alive server is used for keeping alive the communication between the low-power-consumption intelligent equipment and the keep-alive server;
the detection server is used for detecting the keep-alive time interval of the low-power consumption intelligent device channel.
When the detection server performs the keep-alive time interval test, firstly, an interval time is selected, for example, the interval time is 20 seconds, when the interval time is 20 seconds, the detection server sends out a detection response packet to judge whether the low-power-consumption device receives the detection response packet, if the low-power-consumption device receives the detection response packet, the detection response packet is sent immediately, and after the detection response packet is received by the detection server, when the interval time is 20 seconds, the low-power-consumption device channel is in a keep-alive state. At this time, the test interval time can be increased, for example, the test interval time is 25 seconds, when the interval time is 25 seconds, the detection server sends out a detection response packet to determine whether the low-power-consumption device receives the detection response packet, if the low-power-consumption device receives the detection response packet, the detection response packet is sent immediately, and after the detection response packet is received by the detection server, when the interval time is 25 seconds, the low-power-consumption device channel is in a keep-alive state. At this time, the number of seconds of the test interval time may also be continuously increased, for example, the test interval time is 30 seconds, when the interval time is 30 seconds, the probe server sends a probe response packet to determine whether the low-power device receives the probe response packet, if the low-power device does not receive the probe response packet, the probe response packet cannot be sent, and after the probe response packet is not received by the probe server, the keep-alive time of the low-power device channel is kept to 25 seconds. Then, the detection process is exited because the new delta is 2, and the keep-alive interval is 25 seconds.
A low-power consumption device sleep keep-alive method comprises the following steps:
step one, the device initiates connection with a keep-alive server at a conservative initial keep-alive interval tk, and the keep-alive server responds to a connection request;
step two, the device sends a connection with the detection server by adding an increment delta at the initial keep-alive interval tk, and simultaneously locally starts a timer tk + delta +2 to wait for the detection server to initiate a detection packet;
step three, after receiving the detection request, the detection server delays tk + delta to initiate a detection response packet, and if the equipment receives the detection response packet, the equipment immediately sends a detection confirmation packet;
step four, after the detection server receives the detection confirmation packet, the keep-alive server is informed to update the keep-alive interval of the equipment to be tk + delta;
step five, when the equipment keeps alive next time, the keep-alive server informs the use of a new keep-alive interval;
step six, if the device does not receive the detection response packet after the time out of tk + delta +2 after the step two, the device adjusts delta to delta/2 to reinitiate the detection request, and if the device does not receive the detection response packet after the time out of tk + delta +2, the delta is halved again until the delta is less than 3, and the detection is quitted;
and step seven, if the detection request packet is received before tk + delta is overtime in the step six, repeating the step three.
More specifically, in the fifth step, after receiving a new keep-alive interval, the device adjusts the keep-alive interval and initiates a new probe request, where tk + delta.
In the invention, by adopting a mode of dynamically detecting the keep-alive interval, on the premise of ensuring the general adaptability of the equipment, the average sleep power consumption close to the optimal is achieved, the sleep standby time close to the optimal is realized, the standby time is prolonged by 2 to 3 times, and the standby time of the low-power-consumption equipment is improved.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
