Description
Technical Field
The invention relates to the technical field of low power consumption, in particular to a sleep keep-alive system and method for low power consumption equipment.
Background
The low-power consumption network intelligent equipment needs to support a remote wake-up function, and the main technical scheme is that the intelligent equipment and a server keep-alive regularly. Because NAT ageing time of different router configurations is different, the common practice 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, thus leading to shorter standby time of the low-power consumption network intelligent device.
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 out the near maximum NAT aging time 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 near optimal average power consumption, and the system and the method for keeping-alive by dormancy of the low-power-consumption device are used for improving the standby time of the intelligent device.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
a low-power consumption equipment dormancy keep-alive system comprises a low-power consumption intelligent equipment, a keep-alive server and a detection server;
the keep-alive server is used for communication between the keep-alive 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 dormancy keep-alive method for low-power-consumption equipment comprises the following steps:
step one, equipment 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 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 detection server immediately sends a detection confirmation packet;
step four, after the detection server receives the detection confirmation packet, notifying the keep-alive server to update the keep-alive interval of the equipment to tk+delta;
step five, when the equipment is kept alive next time, the keep-alive server informs that a new keep-alive interval is used;
step six, if the device does not receive the detection response packet after the time-out of tk+delta+2 in the step two, the device adjusts delta=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 smaller than 3 and the detection is exited;
and step seven, if the step six receives the detection request packet before the tk+delta times out, repeating the step three.
Preferably, after receiving the new keep-alive interval, the device in the fifth step adjusts the keep-alive interval and initiates a new probe request, tk=tk+delta.
The technical scheme provided by the embodiment of the invention can comprise the following beneficial effects:
compared with the prior art, in the invention, because the bottom current of the current low-power chip is 100-250uA on average, the power consumption peak value of the transmitted protection data can reach 700mA, the average current of the 30s keep-alive interval is 1.6-2mA, and the average current of the 60s keep-alive interval is 0.8-1.2mA. The invention adopts a dynamic detection mechanism to enable the guard interval to be adjusted to 300s under most conditions, the guard interval under partial environments is 600s, and the average power consumption is 250-500 uA.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments.
1-2, a low power consumption device dormancy keep-alive system comprises a low power consumption intelligent device, a keep-alive server and a detection server;
the keep-alive server is used for communication between the keep-alive 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 tests the keep-alive time interval, 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, judges whether the low-power-consumption equipment receives the detection response packet, if the low-power-consumption equipment receives the detection response packet, the detection confirmation packet is immediately sent out, and when the interval time is 20 seconds after the detection server receives the detection confirmation packet, the low-power-consumption equipment channel is in a keep-alive state. At this time, for increasing the test interval time, for example, the test interval time is 25 seconds, when the test interval time is 25 seconds, the probe server sends out a probe response packet, judges whether the low-power-consumption device receives the probe response packet, if the low-power-consumption device receives the probe response packet, the low-power-consumption device immediately sends out a probe acknowledgement packet, and when the probe server receives the probe acknowledgement packet, 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 be further increased, for example, the test interval time is 30 seconds, when the test interval time is 30 seconds, the probe server sends out a probe response packet, determines whether the low power device receives the probe response packet, if the low power device does not receive the probe response packet, the low power device cannot send a probe acknowledgement packet, and after the probe server does not receive the probe acknowledgement packet, the keep-alive time of the low power device channel is kept to be 25 seconds. The probing process is then exited with a new delta of 2 and the keep-alive interval is taken to be 25 seconds.
A dormancy keep-alive method for low-power-consumption equipment comprises the following steps:
step one, equipment 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 adds an increment delta to the initial keep-alive interval tk to connect with the detection server, and simultaneously starts a timer tk+delta+2 to wait for the initiation of the 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 detection server immediately sends a detection confirmation packet;
step four, after the detection server receives the detection confirmation packet, notifying the keep-alive server to update the keep-alive interval of the equipment to tk+delta;
step five, when the equipment is kept alive next time, the keep-alive server informs that a new keep-alive interval is used;
step six, if the device does not receive the detection response packet after the time-out of tk+delta+2 in the step two, the device adjusts delta=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 smaller than 3 and the detection is exited;
and step seven, if the step six receives the detection request packet before the tk+delta times out, repeating the step three.
More specifically, after receiving the new keep-alive interval, the device in the fifth step adjusts the keep-alive interval and initiates a new probe request, tk=tk+delta.
According to the invention, by adopting a dynamic detection keep-alive interval mode, 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 foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
