Embodiment
Below in conjunction with accompanying drawing 1-3 embodiment of the present utility model is made a detailed explanation.
Embodiment: a kind of tunnel energy-saving illuminator, comprise illuminating line and control circuit, illuminating line comprises line 11, step-down circuit 12 and illumination main line 13, line 11 and the step-down circuit 12 illumination main lines 13 that insert in parallel, both switch by control circuit control, step-down circuit 12 is meant the circuit that civil power is powered after transformer B step-down, illumination main line 13 is composed in parallel by several illuminating lamps.
Control circuit utilizes single-chip microcomputer 21 as core, and be aided with peripheral detection input circuit 22, parameter setting circuit 23, illumination control circuit 24, display circuit 25 and failure alarm circuit 26, with 220V civil power dc power supply as single-chip microcomputer and peripheral components after transformation, rectification, voltage stabilizing.
The plug-in of single-chip microcomputer 21 comprises electronic clock, counting unit, vehicle accumulated unit, fault timing unit, pre-sets several parts such as unit, display unit.
Detect input circuit 22 and link to each other, comprise vehicle detection apparatus 27 and coupled signal amplification shaping circuit 28 with the input pin of single-chip microcomputer 21.
Detect input circuit 22 and comprise that inlet detects input circuit and outlet detects input circuit, inlet detects the photoelectric detection system D1 that input circuit comprises amplification and rectification circuit I1 that links to each other with the input pin of single-chip microcomputer 21 and the inlet that links to each other with amplification and rectification circuit I1; Outlet mouthful detection input circuit comprises the photoelectric detection system D2 of amplification and rectification circuit I2 that links to each other with the input pin of single-chip microcomputer 21 and the outlet that links to each other with amplification and rectification circuit I2.When photoelectric detection system D3 or D4 have detected vehicle through out-of-date, promptly produce a pulse signal through amplify, input single-chip microcomputer 21 countings after the shaping.
On 21 two output pins of single-chip microcomputer, be connected with optical coupling isolator E1, E2 respectively, control the line 11 and the step-down circuit 12 of illuminating line respectively.When single-chip microcomputer 21 output 220V illumination control signals, optical coupling isolator E1 is connected, make the coil electricity of direct current relay J1, the normally opened contact J1 closure of direct current relay then, make the coil electricity of A.C. contactor KM1, then the normally opened contact KM1 closure of A.C. contactor is powered thereby line 11 is connected, and illumination lamp ignition provides normal illumination; When single-chip microcomputer 21 output 120V illumination control signals, optical coupling isolator E2 is connected, make the coil electricity of direct current relay J2, the normally opened contact J2 closure of direct current relay then, make the coil electricity of A.C. contactor KM2, then the normally opened contact KM2 closure of A.C. contactor is powered thereby step-down circuit 12 is connected, and lighting is lighted provides the step-down illumination.
