Embodiment
This classroom intelligent power saving device mainly is made up of control circuit supply unit 2, infrared detection device 3 and control light control circuit 4; This classroom intelligent power saving device is provided with input terminal 1 and outlet terminal 5, and input terminal 1 inserts live wire and the zero line of 220V respectively, is control circuit supply unit 2 and electricity consumption facility power; Outlet terminal 5 connects illuminating lamp and other facility; This device is parallel on the live wire and zero line of main circuit by A, the B two control circuit supply unit 2 of naming a person for a particular job, obtain the alternating current of 220V from A, B point, through control circuit supply unit 2 output DC+5V ,+low-voltage DC of 12V, respectively by the related ground connection of C, D, and by C, D point access infrared detection device 3, guarantee the operate as normal of infra-red detection device 3, play on-off action for E, F two ends; The electric current that contains switch control inserts control light control device 4 circuit by G, H at 2, D1, D2 connect by the G point, D3, D4 connect by the H point, variable resistor R12 connects back in parallel with preceding two branch roads in the outer end with photo resistance MG45 by the I node, constitute a rectification circuit and an adjustable voltage divider, and be connected with electric light by outlet terminal.
In Fig. 1, when brightness is lower than a certain value, and the people is arranged in induction region when movable, relay closes, E, F end turn-on lamp is bright, with the brightness of the difference control lamp of extraneous light; After the people walks, to delay time 15 seconds, relay E, F turn-off lamp do not work; Light modulation is to have on people's the basis; regulate the current potential that I is ordered by R12 and MG45 dividing potential drop; different magnitudes of voltage obtains the back from the I node and receives IGBT control end O by voltage-stabiliser tube D5; realization is to the control of the angle of flow of IGBT; thereby realized that control flows to the size of current of lead-out terminal through IGBT; also just realized adjusting bright to lamp, dark degree, realized the function of light modulation as required, R13 plays the effect of protection IGBT.
In Fig. 2, A, B are connected on the live wire and zero line of main circuit, acquisition～220V alternating current, through common transformer be depressurized to～24V about, become direct current by rectifier bridge, get DC+12V through 7812, cross 7805 and obtain DC+5V, wherein C1, C2, C3, C4 are respectively applied for filtering, and the 7812, the 7805th, integrated voltage stabilizing IC, can obtain so required+12V ,+the 5V power supply, connect C, D the end respectively with structure chart in corresponding joining.
In Fig. 3, BIS0001 mixes special circuit by the human-body infrared sensing digital-to-analogue that operational amplifier, voltage comparator, state controller, time of delay, timer and blocking time timer etc. constituted; MG-45 is photo resistance, is used for testing environment illumination, and when as illumination control, if environment is brighter, the resistance value of R3 can reduce, and makes the input of pin 9 remain low level, thereby blocks triggering signal Vs; SW1 is the working mode selection switch, and when S1 is communicated with 1 end face, but chip BISS0001 is in repeated trigger worker and mode; When SW1 was communicated with 2 ends, chip BISS0001 then was in not reproducible triggered mode of operation; Output delay time Tx is worth the 24567xR9C7 for Tx ≈ by the R9 of outside and the big ditty of C7; Trigger the size adjustment of blocking time Ti, be worth 24xR10C6 for Ti ≈ by the R10 and the C6 of outside.
