Embodiment
The invention provides many applicable creative concepts, this creativeness concept can be reflected in a large number of in concrete context.The specific embodiment of describing in following embodiments of the present invention is only as the exemplary illustration of specific implementation of the present invention, and do not form limitation of the scope of the invention.
Communication means embodiment:
Referring to Fig. 1, there is shown the flow chart of a kind of wireless communications method that the embodiment of the present invention provides.As shown in the figure, the method comprises:
Communication steps S1, carries out radio communication according to default communication cycle.Wherein, communication cycle comprises communication period for transmitting and receive data and does not carry out any quiet period of communicating by letter.
Particularly, referring to Fig. 2, the period T 3 shown in figure is a communication cycle, and each communication cycle includes communication period T1 and quiet period T2.At communication period T1, transmit and receive data, communicate with external device, communication period T1 finishes the laggard quiet period T2 of entering, and at quiet period T2, does not carry out any communication with external device, after quiet period T2 finishes, enter again next communication period T1, constantly repeat said process.
Execution step S2 carries out non-traffic operation task in quiet period.Wherein, non-traffic operation task can be any other operation task except traffic operation, for example, obtain temperature information, flash read-write wiping operation etc.
Can find out, the present embodiment periodically communicates with external device, and communication period and external device communicate, and quiet period is not carried out any communication with external device, but in quiet period, can carry out other any operation tasks except communication.This kind of periodic communication mode can be saved equipment power dissipation widely, reduces the fluctuation of system voltage, improved the stability of system.In addition, the present embodiment is in communication process, do not carry out any other operation tasks except communication, avoided communication period due to the interruption of communication process and the reduction of transmission rate that other non-traffic operation tasks of execution cause, guaranteed the stability of communication process.
In above-described embodiment, if the time of implementation of non-traffic operation required by task is shorter, in the time of can completing in a quiet period, just can complete so this non-traffic operation task in a quiet period; If but the time of implementation of non-traffic operation task be greater than quiet period, this non-traffic operation task is divided into several child-operation tasks, and the time of implementation of each child-operation task is all less than quiet period.Preferably, the time of implementation of each child-operation task is identical.With a complete Flash, being operating as example below describes this decomposition implementation:
