The specific method comprises the following steps:
the client side sends a short data packet (namely a heartbeat packet) to the server at regular time in a Timer event, then starts a low-level thread, continuously detects the response of the server in the thread, and if the response of the server is not received in a certain time, the client side is considered to be disconnected.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic method flow diagram of an embodiment of the present invention, and as shown in fig. 1, a heartbeat control method implemented in the embodiment mainly includes:
step 101, when an application needing heartbeat control is newly added in a terminal, a heartbeat Task of the application is executed new Adding to the current heartbeat task set G task In (1).
In this step, when an application requiring heartbeat control is newly added to the terminal, a heartbeat Task of the application needs to be executed new Adding to the current heartbeat task set G in the terminal task So as to be based thereon thereafterHeartbeat task set G task And uniformly controlling the heartbeat events required to be executed in the terminal.
Step 102, judging the G task If there is only one task, if yes, execute step 103; otherwise, step 104 is performed.
In this step, the heartbeat Task is new Adding to the Heartbeat task set G task Then, if G is task Whether or not there is only Task new This Task then needs to execute step 103, using Task new Otherwise, the step 104 is executed to perform the operation on the existing control parameters (including the heartbeat period T) new The count number of heartbeat tasks) to ensure that the control parameters can cover the heartbeat control requirements of all heartbeat tasks.
Step 103, master control period T main Set as the Task new Heart cycle T of new With said T main Starting a master control timer for timing time length according to the T new And said T main Setting the Task new The number of counts of (c); step 107 is performed.
In this step, the Task is set new The specific method of counting the number of times of (2) is as follows:
the Task is processed new Is set as the T new And said T main The rounding of the ratio.
Specifically, since T is at this time new And T main Are identical, therefore, here Task new Is actually set to 1.
It should be noted that, in the embodiment of the present invention, for each application with a heartbeat control requirement, a count number needs to be configured for its corresponding task, and then, the count number is updated correspondingly every time the master timer times out, so as to control triggering of a corresponding heartbeat event based on the count number.
104, judging that the current master control timer is overtime, and if yes, executing a step 105; otherwise, step 106 is performed.
In this step, considering that the master timer is started at this time, in order to ensure the on-time execution of the heartbeat event of the existing task, if the master timer is overtime, the step 105 of executing the overtime processing process first needs to be performed, and then the step 106 of executing the step 106 of updating the control parameters according to the heartbeat cycle of the newly added task is performed, otherwise, the step 106 of directly executing the step of updating the control parameters according to the heartbeat cycle of the newly added task is performed.
Step 105, executing a timeout processing procedure, including: with the current said T main Restarting the master control timer for the timing duration; according to the G task Finding out the task which needs to execute the heartbeat event at present and executing the corresponding heartbeat event according to the counting times of each task; for the G task The counted number of each task in the group is updated overtime.
In this step, in the process of executing timeout processing, the G needs to be processed task Is updated over time to ensure that G is said to follow task Each task in (a) is able to execute a respective heartbeat event in time when the respective heartbeat cycle arrives.
Preferably, in this step, the following method can be adopted according to the G task The number of counts of each task in the database is used for finding out the task which needs to execute the heartbeat event at present:
subjecting the G to task And determining the task with the middle counting number of 1 as the task which needs to execute the heartbeat event currently.
Here, if the counted number of times of the task is 1, it is described that the heartbeat event execution time of the corresponding task is currently reached, and therefore, the heartbeat event of the task needs to be executed.
Preferably, in this step, the following method can be adopted for G task The count number of each task is updated overtime:
for the G task If the counting number of the task is 1, updating the counting number of the task to the heartbeat cycle of the task and the current T main And (4) rounding the ratio, otherwise, subtracting 1 from the counting number of the task.
Step 106, executing a control parameter updating process, including: according to the T new And said T main Judging whether the T needs to be updated or not main According to the judgment result, for the T main And said G task And correspondingly updating the counting times of the middle tasks.
Preferably, the execution control parameter updating process may be implemented by the following method:
if said T is new Less than said T main Then the T is added main Is updated to the T new And for said G task The counting times of the task are set as the heartbeat period and the T of the task main The rounding value of the ratio.
If said T is new Greater than or equal to T main Then the Task is executed new Is set as the T new And said T main The rounding of the ratio.
In the above updating process, if T is the same as T new Less than said T main Then the T is added main Is updated to the T new Thus, can make T main Is always the G task The minimum value of the heartbeat periods of all the tasks in the terminal, and the timing duration of the master timer in the terminal is T main And thus, can ensure timely execution of the heartbeat event that can satisfy all tasks.
In addition, in the updating process, for one task, the heartbeat cycle of the task and the T are used main And taking the rounded result of the ratio as the counting number of the task. Therefore, by the method, a plurality of tasks with different heartbeat cycles (for example, several tasks with close heartbeat cycles) can have the same counting times, and the tasks can trigger the execution of the heartbeat event at the same time, so that compared with the existing method that each application needs to trigger the heartbeat event respectively, the method can effectively reduce the awakening times of the CPU.
And 107, when the master control timer is overtime, executing the overtime processing process.
In the method, when the master control timer in the terminal is overtime, the task which needs to execute the heartbeat event at present is triggered in a unified manner, so that the execution of a plurality of heartbeat events can be triggered when the CPU is awakened once, the number of times of awakening the CPU is effectively reduced while the heartbeat event of each task can be timely triggered, the heartbeat power consumption of the terminal can be further reduced, and the problem of larger heartbeat power consumption caused by the independent control of the execution of the heartbeat event by each application is effectively avoided.
