The invention also proposes a computer-readable storage medium, on which a computer program is stored which, when being executed by a processor, carries out the steps as described above.
Example one
Referring to fig. 2, a first embodiment of the present invention is: a method for keeping long connection with low power consumption can be applied to a mobile vehicle-mounted terminal; the method is based on a vehicle networking system, the vehicle networking system is composed of a remote server and a mobile vehicle-mounted terminal, and data communication is carried out between the remote server and the mobile vehicle-mounted terminal through a mobile network.
The remote server requires that a heartbeat maintenance period Tb is smaller than a certain value T1 for each mobile vehicle-mounted terminal link based on system resource balance consideration, and when the heartbeat data of the mobile vehicle-mounted terminal is not detected within the time T1 of the remote server, the data link is disconnected, and resources are recovered. Also in the mobile network, the mobile operator sets a life cycle T2 for the communication link of the mobile station (such as a mobile vehicle-mounted terminal) based on the consideration of effective utilization of channel resources, and when the base station detects that the idle time of the communication link of the mobile station is greater than T2, the base station will actively disconnect the communication link of the mobile station.
Under the condition that a vehicle stops working and long connection is guaranteed at the same time, a dormant heartbeat maintenance period Ts of a mobile vehicle-mounted terminal is close to min (T1 and T2) as far as possible, but for base stations in different regions and networks of different systems, T2 values are different, and T1 values of different remote servers are also different, so that the Ts needs to be dynamically adjusted to optimally realize balance of low power consumption and long connection.
In the present embodiment, the description will be made separately from the change of the heartbeat maintenance cycle in different vehicle states, in which the vehicle ON or off state is recognized by the ignition switch signal ACC or IG _ ON.
When a vehicle is started, a communication link is established between the vehicle-mounted terminal and a remote server, and the maximum heartbeat maintenance period T1 of the remote server is obtained; then setting a normal heartbeat maintenance period Tw between the vehicle-mounted terminal and the remote server according to the maximum heartbeat maintenance period T1 of the remote server; preferably, T1/2 < Tw < T1.
When the vehicle is in a starting state, the vehicle-mounted terminal sends heartbeat data to the remote server according to the normal heartbeat maintenance period, namely heartbeat maintenance is carried out in a period of Tb Tw. In the normal working state of the vehicle, the mobile vehicle-mounted terminal still has a large amount of service data to interact with the remote server, so that the current state does not need to pay attention to whether Tb is larger than T2.
When the mobile vehicle-mounted terminal detects that the vehicle is flamed out, in order to maintain long connection and ensure low power consumption, interaction of other service data is stopped, the mobile vehicle-mounted terminal enters a dormant state, and only the operation of a heartbeat mechanism is reserved. At this time, firstly, judging whether the optimal sleep heartbeat cycle Tc is valid, that is, judging whether the optimal sleep heartbeat cycle Tc is stored in the nonvolatile storage medium, that is, judging whether the optimal sleep heartbeat cycle has been obtained before, if so, setting the initial sleep heartbeat cycle as the optimal sleep heartbeat cycle, that is, making Ts equal to Tc; if not, setting the initial sleep heartbeat period as the normal heartbeat maintenance period, namely setting Ts as Tw. And meanwhile, setting the period of the automatic wake-up signal of the RTC module as the initial sleep heartbeat period Ts. Therefore, the above steps correspond to setting an initial auto-wake-up signal period.
Then, the whole vehicle-mounted terminal enters a low-power-consumption sleep state, a first flag bit valid is initialized to false, and a second flag bit cnt is initialized to 0, wherein the first flag bit represents whether the current automatic wake-up signal period successfully receives a heartbeat response of the remote server, the value is true, the success is represented, and the value is false, the failure is represented; the second flag bit indicates whether the last automatic wake-up signal cycle successfully receives the heartbeat response of the remote server, the value is 1, which indicates failure, and the value is 0, which indicates success.
When the vehicle is in a flameout state, the vehicle-mounted terminal judges the network connection state according to whether the heartbeat response is received in the sleep state or not to dynamically adjust the automatic wake-up signal period to obtain an optimal sleep heartbeat period, and then the heartbeat maintenance is carried out according to the optimal sleep heartbeat period, so that the balance of the long-connection communication and low-power consumption functions can be realized. Specifically, as shown in fig. 2, the method includes the following steps:
s101: and the vehicle-mounted terminal sends heartbeat data to the remote server according to the automatic wake-up signal period. Specifically, when the automatic wake-up signal period Ts is reached, the RTC module automatically outputs a wake-up signal to wake up the vehicle-mounted terminal, and the vehicle-mounted terminal immediately sends heartbeat data to the remote server after being awakened.
S102: and judging whether the heartbeat response sent by the remote server is successfully received, if so, indicating that the data link is normal, executing step S103, and if not, executing step S106.
S103: the first flag bit is set to success, i.e., value is set to true.
S104: and (4) judging whether the second flag bit is successful, namely judging whether cnt is equal to 0, if so, executing step S105, otherwise, keeping the period Ts of the automatic wake-up signal unchanged, and executing step S107.
S105: updating the automatic wake-up signal period in a mode of increasing a preset stepping value, namely enabling Ts to be equal to Ts + delta, wherein delta is the preset stepping value, and delta is less than Ts; preferably, δ is 10 s. Step S107 is performed.
S106: setting the first flag bit and the second flag bit as failures, respectively, and updating the auto-wake-up signal period by reducing a preset step value, i.e., making valid equal to false, cnt equal to 1, and Ts equal to Ts- δ. Step S107 is performed.
S107: and if the first flag bit is successful and the second flag bit is failed, determining whether valid is true and cnt is true at the same time, if so, executing step S108, if not, i.e., valid is false or cnt is 0, continuing to perform dynamic adjustment of Ts, i.e., continuing to execute step S101, and if the auto-wakeup signal period is updated, sending heartbeat data to the remote server according to the updated auto-wakeup signal period.
S108: and updating and setting an optimal sleep heartbeat cycle according to the current automatic wake-up signal cycle, namely setting Tc to Ts, and storing the optimal sleep heartbeat cycle to a nonvolatile storage medium, namely to a storage medium which is not lost when power is off. When valid is equal to true and cnt is equal to 1, the value of the automatic wake-up signal period Ts reaches the optimal value under the current network environment, and then the current Ts is kept unchanged until the vehicle runs and starts.
S109: and the vehicle-mounted terminal sends heartbeat data to the remote server according to the optimal sleep heartbeat period Tc.
After the vehicle runs and starts each time, different Ts and Tc under the corresponding network environment are obtained according to the method, and low-power-consumption long connection is realized.
The embodiment realizes the optimal balance of low power consumption and long connection by dynamically acquiring the optimal sleep heartbeat cycle of different network environments and remote server configurations aiming at different operator network configurations and remote server configurations.
