Description
Technical field
The utility model relates to a kind of roam lamp control device, particularly a kind of novel street lamp automatic control system.
Background technology
Some street light automatic control circuit is all comparatively complicated at present, so that manufacturing cost increases, and inaccurate with the predawn control of turning on light and turn off the light between the lights, street lamp generation scintillation, this is because at dusk and be black and white or deceive in vain critical condition dawn, and circuit does not escape well that this critical condition causes.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of novel street lamp automatic control system is provided, and can overcome reliably the problems referred to above and realize street lamp control function.
Its technical scheme is: comprise controller switches S, transformation rectification circuit, photo resistance RG, potentiometer RW, supply with time-base integrated circuit IC, relay K M, A.C. contactor C, described transformation rectification circuit is the DC power supply voltage of 12V with the rectification of 220V alternating current transformation, supply with time-base integrated circuit IC, photo resistance RG connects with potentiometer RW, and potentiometer RW is connected with time-base integrated circuit IC, the output of time-base integrated circuit IC connects relay K M, by the connecting and disconnecting of A.C. contactor C and then control street lamp.
2,6 pin of above-mentioned time-base integrated circuit IC are connected with potentiometer RW, and the output of 3 pin is connected to relay K M.
Above-mentioned transformation rectification circuit comprises that transformer T, bridge heap QL and filter capacitor C connect to form.
The beneficial effects of the utility model are: compare with the comparator control circuit that forms with amplifier, scintillation can not occur in this controller because the illumination at dusk and dawn is unstable, well solved critical problem; In addition, it is simple in structure, and cost of manufacture is low, and precise control can well be promoted the use of.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Among the upper figure: controller switches S, fuse RD, transformer T, bridge heap QL, filter capacitor C, photo resistance RG, potentiometer RW, supply time-base integrated circuit IC, relay K M, A.C. contactor C, street lamp L1-Ln, diode V.
Embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises controller switches S, transformation rectification circuit, photo resistance RG, potentiometer RW, supplies with time-base integrated circuit IC, relay K M and A.C. contactor C, described transformation rectification circuit is the DC power supply voltage of 12V with the rectification of 220V alternating current transformation, supply with time-base integrated circuit IC, photo resistance RG connects with potentiometer RW, and potentiometer RW is connected with time-base integrated circuit IC, the output of time-base integrated circuit IC connects relay K M, by the normally open contact C1 connecting and disconnecting of relay K M control street lamp.
2,6 pin of above-mentioned time-base integrated circuit IC are connected with potentiometer RW, and the output of 3 pin is connected to relay K M.
Above-mentioned transformation rectification circuit comprises that transformer T, bridge heap QL and filter capacitor C connect to form.
Its course of work is: the closing operator switch S, the 220V alternating current is added on the transformer T primary coil by fuse RD, through transformer pressure-reducing, level induces the alternating voltage of a 9V secondarily, through bridge heap QL rectification, filter capacitor C, supply with time-base integrated circuit IC(NE555 again) DC power supply voltage about 12V.Daytime, because photo resistance RG reduces by the illumination resistance so that and the level on the potentiometer RW of its series connection raise, that is 2,6 pin level raise, when reaching 1/3rd supply voltages, the time-base circuit counter-rotating, 3 pin output low levels, the 12V relay K M that 3 pin connect is failure to actuate, its normal opened contact KM1 disconnects 220V A.C. contactor C coil power, A.C. contactor also is failure to actuate, and its normally open contact C1 disconnects road lamp power supply, and street lamp does not work.Arrive when night, because photo resistance RG can not be subjected to illumination or reduced by illumination, its resistance raises, so that the dividing potential drop on the potentiometer RW is very little, that is 2,6 pin level reduce, when level drops to 2/3rds supply voltages, the circuit counter-rotating, 3 pin output high level, relay K M gets the electronic adhesive of doing, and its normal opened contact KM1 is closed, connect the ac contactor coil power supply, A.C. contactor action adhesive, the closed road lamp power supply of connecting of its normally open contact C1, street lamp is lighted.After daytime, can make again photo resistance reduced by the illumination resistance, time-base integrated circuit 2,6 pin level raise, and 3 pin output low level relay electric-loss return, and extinguish thereby make contactor return street lamp.After this be again the course of work of going round and beginning again on " daytime on daytime--evening--".Potentiometer RW is used for adjusting the threshold values (still delaying in advance) of turning on light at dusk.
The utility model is compared with the comparator control circuit that forms with amplifier, and this controller scintillation can not occur because the illumination at dusk and dawn is unstable.This is because the threshold level of comparator is a point, when illumination is unstable, can make the threshold level drift, and the flicker of Critical Light then can occur.And time-base circuit NE555 is quite different, and the monostable circuit that is comprised of it and intrinsic hysteresis voltage can effectively address this problem that is to say, in case crossed this bank, just is not easy to return again, and it is not to be gradual along what become.
