When the screen-throwing connection process runs normally, the running state output is continuously carried out, and when the process is finished, the running state is not reported. Sometimes, the screen throwing process is abnormally disconnected, and in order to optimize the response of the screen throwing connection process, a heartbeat detection process is started in the screen throwing connection process to detect the running condition of the main thread; that is, when the main thread does not report the running state for several seconds, it is regarded that the main thread has not responded, and at this time, the heartbeat detection process may dump the call stack of the "screen connection process" to analyze when the user provides the log, and then reinitialize the "screen connection process".
However, WIFI is initialized for wireless screen-on use when the screen-on connection process is initialized, and initializing WIFI results in failure of vehicle sleep. If the vehicle is in sleep failure, the dark current of the whole vehicle is overlarge after a user turns off the vehicle, so that the phenomenon of power shortage occurs after the vehicle is parked for a period of time.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The method for preventing the sleep failure of the vehicle caused by the screen-throwing initialization is used for solving the problem that the sleep failure of the vehicle caused by the screen-throwing process initialization is prevented when the mobile terminal such as a smart phone and the like are connected with the vehicle-mounted terminal/equipment in a screen-throwing way.
In an embodiment, as shown in fig. 1, a method for preventing a sleep failure of a vehicle caused by screen-throwing initialization is provided, which includes the following steps:
s1: an initialization timer is set, and the initialization timer responds to the starting state of the main thread of the screen throwing connection process and the starting state of the heartbeat detection process respectively.
The initialization timer is a timer, and is used for respectively timing the start of the main thread of the screen-throwing connection process and the start of the heartbeat detection process.
S2: in the heartbeat monitoring process, if the heartbeat signal is not received in the first preset time exceeding the continuous timing of the initialization timer, the heartbeat detection process is forcibly disconnected.
The first preset time may be fine-tuned according to the actual application, for example, 25 seconds. The heartbeat detection process monitors the heartbeat of the main thread of the screen throwing connection process, and when no heartbeat signal is received for more than 25 seconds, the main thread stops reporting the running state and is in a complete disconnection state; at this time, the heartbeat detection process is forcibly disconnected, and the program can be prevented from being locked.
Preferably, before the heartbeat detection process is forcibly disconnected, the timing of the initialization timer is paused to ensure that the vehicle can normally enter a sleep state.
S3: if the heartbeat signal is received in a first preset time for continuously counting the initialization timer, and if the heartbeat signal is not received in a second preset time for continuously counting the initialization timer from the time of receiving the heartbeat signal, initializing a screen-throwing connection process.
The second preset time may be fine-tuned according to the actual application, for example, 5 seconds. That is, after judging whether the main thread is in a completely disconnected state, further judging whether the main thread survives; if the main thread does not survive, the screen throwing process is reinitialized so as to ensure that the vehicle machine can recheck after being awakened.
Preferably, call stack data of the screen-connection process is stored, i.e. the data field is saved, for providing log analysis for the user, before the screen-connection process is initialized.
In the embodiment, the processing logic of the heartbeat detection process and the screen-throwing connection process is optimized, so that the failure of the sleep of the vehicle and the machine caused by the initialization of the screen-throwing connection process is prevented, and the problem that the dark current of the whole vehicle is overlarge after a user turns off the vehicle and the power shortage occurs after the vehicle is parked for a period of time is avoided.
Further, in an embodiment, the method for preventing the screen-throwing initialization from causing the sleep failure of the vehicle machine further includes the steps of:
s4: if the heartbeat signal is received within a first preset time for continuously counting the initialization timer, and if the heartbeat signal is continuously received within a second preset time from the time of continuously counting the heartbeat signal, resetting the initialization timer.
Namely, after the heartbeat signal is received in the first preset time continuously counted by the initialization timer, if the heartbeat signal is continuously received in the second preset time continuously counted from the time when the heartbeat signal is received, the main thread still survives, at this time, the initialization timer is reset so as to monitor the state of the main thread again, and resource waste caused by the fact that the screen connection process is re-initialized by mistake is prevented.
Specifically, the complete data processing flow corresponding to the above steps is shown in fig. 2. The screen-throwing connection process corresponds to the heartbeat detection process, and a main thread under the screen-throwing connection process triggers an initialization timer to count when being started; at the same time, when the heartbeat detection process is started, the initialization timer is triggered to count. In the heartbeat monitoring process, the heartbeat data of the main thread is monitored and acquired by a monitoring thread under the heartbeat detection process.
Judging whether the main thread is completely disconnected according to the first preset time of the initialization timer, and if the heartbeat data is not received after the first preset time (such as 25 seconds) is exceeded, suspending the initialization timer first and then forcibly disconnecting the heartbeat detection process.
When the heartbeat data is received within the first preset time (for example, 25 seconds), further judging whether the main thread survives, namely, continuing to count the second preset time (for example, 5 seconds) from the time of receiving the heartbeat data, and if the heartbeat signal is received within the second preset time, resetting an initialization timer to count the heartbeat monitoring process again in order to avoid the false reinitialization of the screen throwing connection process.
If the heartbeat signal is not reached within the second preset time, the main thread is not survived and needs to be reinitialized, at the moment, call stack data of the screen throwing connection process are stored first and saved as a log file for later analysis; and initializing a screen-throwing connection process, so that the vehicle machine can recheck after being awakened.
In an embodiment, a device for preventing a failure of sleep of a vehicle caused by screen-throwing initialization is provided, which comprises:
the timer setting module is used for setting an initialization timer which respectively responds to the starting state of the main thread of the screen throwing connection process and the starting state of the heartbeat detection process;
the forced stopping module is used for forcibly disconnecting the heartbeat detection process if the heartbeat signal is not received in the heartbeat monitoring process beyond the first preset time continuously counted by the initialization timer;
the restarting module is used for initializing the screen-throwing connection process if the heartbeat signal is received in a first preset time continuously counted by the initializing timer and if the heartbeat signal is not received in a second preset time continuously counted from the time of receiving the heartbeat signal;
the storage module is used for storing call stack data of the screen throwing connection process;
the timer resetting module is used for resetting the initialization timer if the heartbeat signal is received in a first preset time for continuously counting the initialization timer and if the heartbeat signal is continuously received in a second preset time for continuously counting the heartbeat signal;
and the timer pause module is used for pausing the initialization timer before the screen-throwing connection process is initialized.
In this embodiment, the function of the device for preventing the sleep failure of the vehicle-mounted device by screen-mounted initialization corresponds to the method for preventing the sleep failure of the vehicle-mounted device by screen-mounted initialization one by one, and will not be described herein.
In one embodiment, a computer device is provided, including a memory, a processor, and a computer program stored in the memory and capable of running on the processor, where the processor executes the computer program to implement steps of the method for preventing a failure of sleep of a vehicle caused by screen-dropping initialization in the above embodiment, for example, steps S1 to S3 shown in fig. 1.
