Step (3): CPU continue to monitor whether button K has input, i.e. ab=11, if, then making GPIO1=0, the GPIO2 input is invalid, GPIO3=0, GPIO5=0, SW adds 1, and namely protective cover begins to descend;
In the protective cover decline process, the input of button K, transducer C is invalid, and namely this moment, ab=00, GPIO2 input was invalid.
Be that button K is pressed again, the SW flag bit adds 1, becomes 0x03, GPIO5, GPIO6 output low level, and GPIO4, GPIO7 export high level, relay B conducting, automatically rotating shaft B work, rotating shaft A buckle and screens break away from automatically.
Step (4): in protective cover decline process, CPU monitors whether transducer D is triggered, if then SW adds 1, GPIO4=1, protective cover stops to descend;
After transducer D is triggered, GPIO1=0, GPIO2 input invalid, GPIO3=1, GPIO4=1, GPIO5=1, SW=0, ab=01; Protective cover drops to the bottom; inductor D is triggered; the SW flag bit becomes 0x00; GPIO4, GPIO5, GPIO6, GPIO7 export high level; automatically rotating shaft B quits work; automatically rotating shaft A buckle and screens combine, and this moment, the protective cover backrush was on the coaxial hollow cylindrical tube of automatic rotating shaft B.
When protective cover descend complete after, GPIO1=0, GPIO2 input is invalid, GPIO3=0, GPIO4=1, GPIO5=1, GPIO6=1, GPIO7=1, SW=0, ab=01, namely touch screen protection device is in the state state.
In this method, when rotating shaft A, B quit work automatically, buckle and the screens of A, B all combined, i.e. GPIO6=1, GPIO7=1, the fixedly position of protective cover.
In this method; if portable terminal is mobile phone; then for the user can be received calls after protective cover rises easily; can be when incoming call be arranged; in the situation that do not open protective cover; be flag bit ab=1; during the SW=0x02 state; mobile phone is reported incoming information automatically; make things convenient for the user to determine whether receive calls, because incoming call automatic number reporting functional module is prior art, consolidate in the invention and introduce no longer in detail; as long as flag bit is eligible, CPU can directly control the work of existing incoming call automatic number reporting functional module.Certainly, the answering mode of mobile phone also can be set " answering by Answer Key ", " pressing any key answer " for, and various ways such as " the protective cover on-off mode are answered ".
