Description
Technical field
The utility model belongs to the lighting apparatus control device, is specifically related to a kind of photosensitive intelligent controller of lighting apparatus.
Background technology
The street lamp opening/shutting mode mainly divided time control and two kinds of real-time Artificial Control automatically in the past, the time automatic control is the seasonal variations setting program by sunrise sunset, be used for controlling bright lamp and light-off, though than Artificial Control advanced person, but as or strong wind airborne dust at the sleet cloudy day the dusk, street lamp still follow procedure does not slowly work, and it is inconvenient that people will feel.Light-operated then is to drive microcomputer chip by light-inductive, just lights street lamp when the illuminance of street lamp environment of living in is lower than 15LX, when dawn is just closed street lamp during greater than 8LX, thereby makes street lighting be the traffic service better.But problems such as simple photosensitive control because light sensor is subject to Temperature Influence, is controlled instability, and precision is not high.
Summary of the invention
The photosensitive intelligent controller that provides a kind of control precision high is provided the purpose of this utility model, to address the above problem.
The technical solution of the utility model is: photosensitive intelligent controller, it comprises light sensor, it is characterized in that: it also comprises temperature sensor and temperature-compensating light sensor, and sensor signal is connected to main control singlechip after analog-to-digital conversion, and main control singlechip is the back output control circuit after testing; Main control singlechip also connects the time control circuit of control detection.
Described sensor signal realizes input by shielded type cable.

Embodiment
As shown in Figure 1, transducer comprises temperature sensor 4, light sensor 1,2 and temperature-compensating light sensor 3, and the signal of sensor line is connected on the indoor control unit 6 by shielded type cable 5.Indoor control unit 6 comprises main control singlechip 61 as shown in Figure 2, and main control singlechip 61 connects the time control circuit 62 of control detection, light-emitting diode display and input button 63 and output control circuit 64.
As shown in Figure 3, main control singlechip 61 adopts PIC18F252, and main control singlechip 61 connects power circuit U1, and the transducing signal input connects J6, and time control circuit comprises chip PCF8563T and DC power supply ST1; Output control circuit comprises optical coupler U4, U5, and the output of optical coupler even meets triode amplifier T2, T3 respectively, and the output of triode amplifier is connected to control output interface J3.Control output interface J3 is connected to and lock output relay and separating brake output relay.
The control output.Two-way output, the one tunnel for closing a floodgate, and one the tunnel is separating brake, is the output of 1 pps pulse per second signal.Can cooperate with protective relaying device.
Operation principle is: the temperature-compensating light sensor, this transducer is by the light source irradiation of constant brightness, make its output voltage only be subjected to the influence of temperature drift, single-chip microcomputer carries out COMPREHENSIVE CALCULATING according to the temperature information of this sensor output voltage and temperature sensor, and the temperature that calculates light sensor is floated coefficient; Directly in the face of outdoor, avoid the sunlight direct projection, make the scattered light of its acceptance open air, under this kind layout, single-chip microcomputer can more effectively avoid scattered high light to cause the equipment malfunction work to the intensity of illumination calculating mean value; The degree transducer, this transducer provides temperature parameter; The time control circuit control single chip computer detects in the setting-up time section;
The voltage that light sensor output changes with intensity of illumination, variations in temperature, temperature compensation sensor is exported the voltage signal that only varies with temperature and change, single-chip microcomputer carries out analog-to-digital conversion to this signal respectively, the signal of temperature sensor and temperature-compensating light sensor is carried out computing, calculate the temperature drift coefficient of light sensor, single-chip microcomputer is done temperature-compensating according to temperature drift coefficient to the light sensor signal subsequently, extracts the correct magnitude of voltage that only reflects intensity of illumination.
The output of outdoor transducer is aanalogvoltage, by shielded type cable the signal of telecommunication is transferred in the controller in the control room, for the controller collection, uses the cable of band screen can effectively reduce extraneous interference.
Time control circuit only meets the special time period that sets in advance as the another basis for estimation of control street lamp, and single-chip microcomputer just can go to check intensity of illumination, just controls output unit and do corresponding action when intensity of illumination meets the scope of setting.The dual judgement of time and intensity of illumination has improved the reliability and the accuracy of this controller.
