Wherein, as shown in Figure 3, central processing module 50 comprises further: first judges that signal receiving end 501, second judges that signal receiving end 502, the 3rd judges signal receiving end 503 and control signal transmitting terminal 504; First memory module 303 and first judges that signal receiving end 501 is connected, and first judges that signal receiving end 501 receives first signal of telecommunication coming from the first memory module 303 and export; By phase inverter 305 and second, second memory module 304 judges that signal receiving end 502 is connected, second judges that signal receiving end 502 receives second signal of telecommunication coming from through phase inverter 305 and export; First collection signal comprises first signal of telecommunication and second signal of telecommunication; Secondary signal acquisition module 40 and the 3rd judges that signal receiving end 503 is connected, and the 3rd judges that signal receiving end 503 receives the second collection signal coming from secondary signal acquisition module 40 and export; When the difference of the magnitude of voltage of first signal of telecommunication and second signal of telecommunication is in preset range, and when the magnitude of voltage of the second collection signal is greater than predetermined threshold value, central processing module 50 control signal transmitting terminal 504 exports control signal.In order to the approximately equalised situation of the magnitude of voltage defining first signal of telecommunication and second signal of telecommunication more accurately, the present invention is provided with preset range when the magnitude of voltage of central processing module 50 to first signal of telecommunication and second signal of telecommunication compares, if the difference of the magnitude of voltage of first signal of telecommunication and second signal of telecommunication is in preset range, then think the magnitude of voltage of first signal of telecommunication and the magnitude of voltage approximately equal of second signal of telecommunication.
Alternatively, as one embodiment more specifically, the first memory module 303 comprises the first electric capacity, and the second memory module 304 comprises the second electric capacity, and secondary signal acquisition module 40 comprises the 3rd electric capacity; First switch module 301 comprises the first transistor, and the input of the first switch module 301 is the anode of the first transistor, and the output of the first switch module 301 is the negative electrode of the first transistor; Second switch module 302 comprises transistor seconds, and the input of second switch module 302 is the negative electrode of transistor seconds, and the output of second switch module 302 is the anode of transistor seconds.The first transistor and transistor seconds are chosen as commutation diode, commutation diode can carry out rectification process to the pulse electrical signal that the first nano generator 10 exports, commutation diode also serves the effect of switch simultaneously, for controlling the flow direction of the pulse electrical signal that the first nano generator 10 exports.
Particularly, when the first nano generator 10 exports the first forward signal of telecommunication, the first transistor conducting, transistor seconds ends, the electric energy of the first forward signal of telecommunication inputs to the first electric capacity i.e. the first memory module, and is exported as first signal of telecommunication by the magnitude of voltage of the first forward signal of telecommunication of the first capacitance stores; When the first nano generator 10 exports the first reverse signal of telecommunication, the first transistor ends, transistor seconds conducting, the electric energy of the first reverse signal of telecommunication inputs to the second electric capacity i.e. the second memory module, and is exported as second signal of telecommunication by the magnitude of voltage of first of the second capacitance stores reverse signal of telecommunication.In addition, the second forward signal of telecommunication that the second nano generator 20 exports by the 3rd electric capacity and secondary signal acquisition module stores, and is gone out as the second collection signal by the magnitude of voltage of the second forward signal of telecommunication of the 3rd capacitance stores.Wherein, the first electric capacity, the second electric capacity and the 3rd electric capacity can be polystyrene electric capacity.
Alternatively, as shown in Figure 3, intelligent flushing system also comprises timer 80; Timer 80 is connected with central processing module 50, when the difference of the magnitude of voltage of first signal of telecommunication and second signal of telecommunication is in preset range, during the magnitude of voltage approximately equal of the i.e. magnitude of voltage of first signal of telecommunication and second signal of telecommunication, timer 80 starts timing and the first timing time is sent to central processing module 50; When the magnitude of voltage of the second collection signal is greater than predetermined threshold value, namely have excreta to act on the second nano generator 20, timer 80 starts timing and the second timing time is sent to central processing module 50.Alternatively, timer 80 also can be a part for central processing module 50, and namely central processing module 50 itself has clocking capability.
When the first timing time is more than or equal to default very first time threshold value, and when the second timing time is more than or equal to the second default time threshold, central processing module 50 controls control signal transmitting terminal 504 and exports control signal.
Wherein, when the first timing time is more than or equal to default very first time threshold value, illustrates and leave again after having user to come around toilet, but can not affirm whether this user used toilet; When the second timing time is more than or equal to the second default time threshold, illustrate in toilet have excreta; And by both in conjunction with judgement, can be determined with after user used toilet and need to wash by water, and according to the size of the second collection signal magnitude of voltage, central processing module 50 also can judge that excreta acts on the pressure size on the second nano generator 20, i.e. excremental weight, thus control the discharging quantity of water of flushing device 60, make not residual excreta in toilet.
Alternatively, when timer 80 record first judge that the interval time that first signal of telecommunication that signal receiving end 501 receives and second judges between second signal of telecommunication that signal receiving end 502 receives is less than the 3rd default time threshold time, central processing module 50 sends reset signal to the first memory module 303 and the second memory module 304, and the electric energy of the first memory module 303 and the second memory module 304 resets.Namely first signal of telecommunication and second signal of telecommunication are very short for interval time of exporting, the 3rd time threshold such as preset is 30s, may be then that clean user person occurs in the situation of cleaning or other non-normal use toilet, therefore central processing module 50 can be regarded as false positive signal ignores, namely the electric energy of the first memory module 303 and the second memory module 304 is reset, proceed to detect.
