In the present embodiment, described mobile terminal can comprise various types of equipment such as mobile phone, panel computer or palm PC.In other words, described data acquisition facility can be arranged at existing various with in the terminal device of touch-screen, and the present invention does not limit this.
By reference to the accompanying drawings the course of work of the mobile terminal of the present embodiment is described in further details again below.
Fig. 3 shows the schematic flow sheet of the interrupt module of the present embodiment.With reference to figure 3, after described mobile terminal-opening starts, namely perform step S11: interrupt module startup optimization;
Perform step S12: judged whether that look-at-me produces;
If there is look-at-me, then described interrupt module performs step S13: interrupt flag bit is set to the first state, and receives the touch signal on touch-screen;
If there is not look-at-me, then return and perform step S11, namely described interrupt module continues to run.
Fig. 4 shows the schematic flow sheet of the poller module of the present embodiment.With reference to figure 4, described poller module every predetermined interval time and startup optimization once, namely performs step S21: the state of poller module interrupt flag bit described in time detecting at predetermined intervals;
Then step S22 is performed: judge whether described interrupt identification is the first state;
When described interrupt flag bit is not the first state, described poller module performs step S23: obtain the touch signal on touch-screen.
In the present embodiment, described poller module can not perform any action when described interrupt flag bit is the first state, and maintains running status, until after predetermined interval time, again performs and detects action.
In the present embodiment, interrupt flag bit is set to the first state by described interrupt module after receiving look-at-me, otherwise described interrupt flag bit is the second state; And poller module is when interrupt flag bit is the second state (namely because the reasons such as touch screen inefficacy cause look-at-me to produce), the function that interrupt module completes the touch signal obtained on touch-screen can be substituted, even if after this ensures that thering touch-screen inefficacy, still can operate accordingly timely and effectively, thus improve the stability of system; And need not reprocess immediately, also greatly reduce cost, improve the experience of user.
Fig. 5 shows the structural representation of the embodiment two of mobile terminal of the present invention; With reference to figure 5, the difference part of the mobile terminal embodiment one of the present embodiment is: described interrupt module 11 also comprises timing unit 114 and the second setting unit 115; Described poller module 12 also comprises closing unit 123.Similar in other unit in the present embodiment and embodiment one, does not repeat them here.
Particularly, the timing unit 114 in interrupt module 11 connects described trigger element 111, is suitable for resetting and timing when receiving described first trigger pip, produces the second trigger pip when clocking value is greater than time threshold.
Described second setting unit 115 connects described timing unit 114 and described memory module 13, is suitable for, according to described second trigger pip, described interrupt flag bit is set to the second state.
Closing unit 123 in described poller module connects described detecting unit 121, is suitable for closing described poller module 12 when described interrupt flag bit is the first state.
The course of work of the mobile terminal of the present embodiment and the difference part of embodiment one are: in the present embodiment, the trigger element 111 of described interrupt module 11, after the look-at-me receiving touch-screen transmission, also can produce the first trigger pip and resets to make described timing unit 114 and restart timing; After clocking value is greater than default time threshold, described timing unit 114 produces the second trigger pip, to trigger the second setting unit 115, the interrupt flag bit in memory module 13 is set to the second state.Like this, after poller module 12 starts, the touch signal on touch-screen can be obtained according to the interrupt flag bit of the second state, thus avoid and caused obtaining the problem of touch signal because touch-screen loses efficacy, improve the stability of system.
In the present embodiment, described time threshold reasonably can be arranged according to practical application, so just can in rational time range, the second state is arranged in the interrupt flag bit conversion being configured to the first state owing to receiving look-at-me, thus ensure after touch-screen lost efficacy, described poller module can substitute interrupt module in time to realize the function of the touch signal obtained on touch-screen, and then the stability of further raising system.
On the other hand, automatically can close when interrupt flag bit is the first state in described poller module, thus effectively save electricity, reduce power consumption.
Although the present invention discloses as above, the present invention is not defined in this.Any those skilled in the art, without departing from the spirit and scope of the present invention, all can make various changes or modifications, and therefore protection scope of the present invention should be as the criterion with claim limited range.
