Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the energy-conservation liquid crystal information terminal of the utility model.
Embodiment
As shown in Figure 1, be the structural representation of the energy-conservation liquid crystal information terminal of the utility model.Energy-conservation liquid crystal information terminal disclosed in the utility model comprises: first induction module 1, second induction module 2, logic decision module 3, touch screen induction module 4 and liquid crystal system CPU module 5.
Wherein first induction module 1 and second induction module 2 are used for the human body induced signal and send two kinds of pulse signals respectively according to testing result and give logic decision module 3.First induction module 1 comprises first inductor 11 and a CPU12.First inductor 11 is used for the human body induced signal; The one CPU12 is used for when not having the user to be in the induction zone, continually sends first kind of pulse signal, and continually after detecting the human-induced signal sends second kind of pulse signal.Second induction module 2 comprises second inductor 21 and the 2nd CPU22.Second inductor 21 is used for the human body induced signal; The 2nd CPU22 is used for when not having the user to be in the induction zone, continually sends first kind of pulse signal, and continually after detecting the human-induced signal sends second kind of pulse signal.A described CPU12 and the 2nd CPU22 are continual to send to logic decision module 3 with pulse signal.
Logic decision module 3 is used for kind and the duration according to the pulse signal that receives, and has judged whether that the user is trapped in induction zone or leaves induction zone and send pulse control signal.Touch screen induction module 4 is used for the senses touch signal, just sends the liquid crystal display logical signal when having detected user's touch LCD information terminal.
Logic decision module 3 comprises master cpu 31, timer 32 and switch module 33.Wherein timer 32 picks up counting when a CPU12 and the 2nd CPU22 send second kind of pulse signal, have only when the time that a CPU12 and the 2nd CPU22 send second kind of pulse signal all to surpass threshold time and just assert have the user to be trapped in induction zone, timer 32 sends enable signal at this moment; Master cpu 31 is used to receive the pulse signal of a CPU12 and the 2nd CPU22 output, and after receiving the enable signal that timer 32 sent, master cpu 31 output high-level control signal are given switch module 33.Switch module 33 is made up of triode and relay switch, and triode is connected with master cpu 31, and relay switch is connected with the collector of triode and the IO mouth of liquid crystal system CPU module 5 respectively.Triode conducting, relay switch adhesive when master cpu 31 output high-level control signal, an IO mouth of liquid crystal system CPU module 5 is received a high level signal, liquid crystal system CPU module 5 begins to scan another and connects the IO mouth that touch-screen induction module 4 is connected at this moment, when if this IO mouth also is high level, just judging has the user to be ready operating, system converts normal operating conditions to from sleep state, and it is backlight to open liquid crystal display automatically.
When user's EO leaves induction zone, first inductor 11 and second inductor 21 detect less than the human-induced signal, the one CPU21 and the 2nd CPU22 begin first kind of pulse signal of continual transmission, the pulse signal that the master cpu 31 of logic decision module 3 receives, after becoming first kind of pulse signal from second kind of shift pulse signal, master cpu 31 output low level control signals, triode ends, relay switch disconnects, an IO mouth of liquid crystal system CPU module 5 receives a low level signal, liquid crystal system CPU module 5 scans another simultaneously and connects the IO mouth that touch-screen induction module 4 is connected at this moment, if this IO mouth is a high level, then judge to also have the user operating; If this IO mouth is a low level, just judge the user complete operation leave induction zone, system converts state to from normal operating conditions sleep, it is backlight to close liquid crystal display automatically.
In the present embodiment, first inductor 11 and second inductor 21 adopt infrared inductor, but are not limited to infrared inductor, also can adopt other human inductors.Thereby the size of induction zone is adjusted in the gain that can regulate inductor.
Energy-conservation liquid crystal terminal disclosed in the utility model adopts two induction modules to carry out human-induced signal's detection, have only when two induction modules have all detected the user and be trapped in the induction zone, logic decision module 3 is just sent the brilliant system CPU module 5 of high-level control signal feeding, liquid crystal system CPU module 5 detects the IO mouth that is connected with touch screen induction module 4 simultaneously, when also being high level, this IO mouth just judges have the user to operate, control liquid crystal information terminal is converted to normal operating conditions from sleep state, opens LCD backlight automatically.When induction module is sensed the user when leaving induction zone, liquid crystal system CPU module 5 detects the IO mouth that is connected with touch screen induction module 4 simultaneously, when also being low level, this IO mouth judges that just user's liquid crystal complete operation leaves induction zone, control liquid crystal information terminal is converted to sleep state from normal operating conditions, automatically close LCD backlight, otherwise judge that the user is also operating, the liquid crystal information terminal keeps normal operating conditions.
The above only is a preferred embodiment of the present utility model, not in order to restriction the utility model, all any modifications of being done in spirit of the present utility model and principle, is equal to and replaces or improvement etc., all should be included in the protection domain of the present utility model.
