Embodiment

As shown in Figure 1, the utility model electric appliance energy-saving prior-warning device comprises human body signal detector SJ, logic blocking circuit LB, the first on-off circuit KG1, second switch circuit KG2.The output terminal of human body signal detector SJ is connected with the input end of logic blocking circuit LB, and the output terminal of logic blocking circuit LB is used for being connected with the off signal end GX of electrical equipment mainboard U1.The human body signal detector adopts microwave, infrared couple of prison detector SJ in the present embodiment, and SJ adopts IT producer to develop the TWH type product of typing, operating voltage DC9～16V, working current≤100mA; 0～12 meter of surveillance distance, horizontal view angle are 45 degree sector angles, and the vertical angle of view is 110 degree sector angles; The output contact of SJ has one group of alarm terminals ALARM (it is normally closed that CO often opens the public CC of CN), and SJ self has power switch DK, and DK-1 connects+the 9V terminal, DK-2 connects CO Chang Kaiduan, SJ power supply negative terminal ground connection GND, GND connect with the normally closed terminal of CC simultaneously, and SJ also is provided with a pair of tamper contact.The power end of infrared pair of prison detector of microwave SJ (+9V) be connected with the 3rd end (pin 3) of the first on-off circuit KG1, first end of the first on-off circuit KG1 (pin 1) be used for the power end of electrical equipment mainboard U1 (+9V) be connected, the control end of the first on-off circuit KG1 (pin 2) is used for being connected with early warning signal end REMO on the electrical equipment mainboard U1 (can set up " early warning " button on the telepilot of electrical equipment, realize remote control control the switching of this device).The output terminal of infrared pair of prison detector of microwave SJ is connected with first end (pin 1) of second switch circuit KG2, the control end of KG2 (pin 2) is connected with the CRANK PULSES end ZY of electrical equipment mainboard U1, the 3rd end of second switch circuit KG2 (pin 3) is connected with warning circuit, warning circuit comprises relay K J and audible-visual annunciator 1, coil one end of relay K J is connected with the 3rd end of second switch circuit KG2, other end ground connection, first pair of normally opened contact of relay K J is connected with the signal controlling end of audible-visual annunciator 1; Second pair of normally opened contact of KJ is connected with the end out of service of memory clock 2, and the 3rd pair of normally opened contact of KJ is connected with a key dial-up end 3 of landline telephone, and wherein the first on-off circuit KG1 and second switch circuit KG2 are switch triode; Wherein remember the dialing of clock and landline telephone one key and be prior art.Wherein the 4th of relay K J the pair of normally opened contact and two pairs of normally closed contacts are as standby.

As shown in Figure 1, infrared pair of prison detector of microwave SJ obtains working power from the electric power loop of electrical equipment mainboard U1, and movable in the room as the people, SJ promptly detects mobiles, the action of its alarm terminals ALARM terminal makes the CO-CN junction closure, send alerting signal, at this moment the CN terminal is exported a noble potential, delivers to logic blocking circuit LB, the base stage of its triode VT is noble potential, make triode VT conducting, collector output is electronegative potential, locking off signal GX; The alerting signal of infrared pair of prison detector of microwave SJ has also been delivered to second switch circuit KG2 simultaneously, but what at this moment KG2-2 obtained from electrical equipment mainboard U1 is CRANK PULSES (electronegative potential), this signal can not make the KG2 conducting, so alarm terminals ALARM alerting signal can not be sent.When the electrical equipment people that is in operation has walked, at this moment infrared pair of prison detector of microwave SJ surveys less than mobiles, and alarm terminals ALARM contact resets, and is the CC-CN conducting; The CN terminal is exported an electronegative potential, delivers to logic blocking circuit LB, and triode VT is ended, and its collector output uprises current potential, sends off signal, through time-delay in about 5 minutes, and the electrical equipment shutdown, thus reached the purpose that Bye-byes economizes on electricity.General household electrical appliances all have the function of timing shutdown now, but need manually default; If use this device, just can replace the function of original timing shutdown.After the electrical equipment shutdown, this device is also in running order, changes anti-theft alarm function automatically over to.If at this moment there is mobiles to enter the room, infrared pair of prison detector of microwave SJ moves warning, and the CN terminal is exported a noble potential; At this moment electrical equipment shuts down and is in holding state, the control end of second switch circuit KG2 is received a noble potential, makes the KG2 triggering and conducting, starts expansion relay K J (for reducing false alarm, KG2 also has the time-delay about 5 seconds), relay K J action launching audible-visual annunciator; Output signal to the memory clock simultaneously, the memory clock is stopped, then the time that shows on the clock is time of fire alarming; Also can start fixed line one key dialing simultaneously, call, thereby realize the warning function of this device to home owner.

This device can make up with electrical equipment such as air conditioner, televisors, it is expansion to the household electrical appliances intelligent functions, be installed on air conditioner, televisor top or side (partial installation), also can just be assembled in (hereinafter to be referred as household electrical appliances) inside such as air conditioner, televisor in manufacturing plant, it is more intelligent that household electrical appliances are used.For purchasing household electrical appliances, the user can select to install this device, and at this moment on-off circuit KG1 has not just needed, and is simple to the repacking of household electrical appliances; For household electrical appliances manufacturer, when developing new product, only need to increase the two prison of fritter detector circuit plate, can finish the upgrading of product, increase " early warning " shift knob on the telepilot of new product, the household is on duty when being away from home, and opens as long as press " early warning ", on-off circuit 1 conducting of this device, device promptly enters duty.This device is specially adapted to the air conditioner of financial sector business hall and overlooking retail shop and installs and uses, to unit, house life all having increased security, saves energy simultaneously.

In addition, the warning circuit that the 3rd end of above-described second switch circuit KG2 connects can also be changed to automatic boot circuit, automatic boot circuit comprises relay K J, coil one end of relay K J is connected with the 3rd end of second switch circuit KG2, other end ground connection, the normally opened contact of relay K J is connected (not drawing among Fig. 1) with the starting-up signal end of electrical equipment mainboard.Principle of work is the same, long-time nobody the time, this device shuts down automatically; Different is when detecting human body signal again after the shutdown, and this device can make the electrical equipment start automatically.This kind connected mode relatively is applicable to the advertisement television of office building escalator, and it does not need warning function, but needs automatic open and close machine function.

In conjunction with the accompanying drawings the utility model has been carried out exemplary description above, obviously the utility model specific implementation is not subjected to the restriction of aforesaid way.As long as any unit or individual have adopted method design of the present utility model and technical scheme; the improvement of the various unsubstantialities that carried out; or design of the present utility model and technical scheme are directly applied to other occasions without improving, all within protection domain of the present utility model.
