Background technology
At present, the sensing device that is used for sun-tracing adopt usually power ratio or voltage ratio form discern the position and the variation thereof of the sun.But the structure of comparator circuit is comparatively complicated usually, and used device is more, makes the stability of system and discrimination be not easy control, has also caused the increase of manufacturing cost simultaneously.
Summary of the invention
To be solved by this invention is to overcome the problem that prior art exists, and a kind of sun-tracing photoreceptor is provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of sun-tracing sensor comprises sensor devices and control circuit.
Described sensor devices comprises: sensor devices shell and photoresistance; The light-sensitive surface of photoresistance upwards is arranged on the base plate in shell bottom plate shadow region, with the separatrix, shadow region tangent away from window one side;
Connection between the device of formation control circuit:
One of two photoresistance extension lines of photoresistance is connected with the negative pole of power supply, an end of not gate and an end of relay coil; Another root of photoresistance extension line is connected with the other end of an end of adjustable resistance, not gate and the other end of relay coil; The other end of adjustable resistance connects the positive pole of power supply through switch.
Beneficial effect of the present invention:
The invention has the beneficial effects as follows, under the prerequisite that guarantees control accuracy, avoid using comparator circuit, directly carry out the sensing and the output of light source.Advance to adopt photoresistance, adjustable resistance, relay, not gate (74HC04), mechanism is simple.Can under the triggering of light, directly finish voltage output, save the comparator circuit that common photosensitive device has, improve the reliability and the agility of device simultaneously.

Embodiment
The present invention is further described below in conjunction with accompanying drawing.
A kind of sun-tracing photoreceptor, it comprises: sensor devices and photoreceptor control circuit 11.
Described sensor devices is seen Fig. 2～5, and it comprises: sensor devices shell 8 and photoresistance 1; The light-sensitive surface of photoresistance 1 upwards is arranged on the base plate in shell bottom plate shadow region 2, on the tangent center line in separatrix, shadow region 5, is positioned at away from window one side.The aperture of two diameters 1 to 2mm that two photoresistance extension lines 7 are accomplished fluently from sensor devices shell 8 base plates in advance passes.
Connection between the device of formation photoreceptor control circuit 11, see Fig. 1:
One of two photoresistance extension lines 7 of photoresistance 1 is connected with the negative pole of power supply 13, an end of not gate (74HC04) 17 and an end of relay coil 18; Another root of photoresistance extension line 7 is connected with the other end of an end of adjustable resistance 15, not gate (74HC04) 17 and the other end of relay coil 18; The other end of adjustable resistance 15 connects the positive pole of power supply 13 through switch 14.Not gate also comprises 74LS04,74LS14 etc.
When the light-sensitive surface window vertical irradiation of sunray and sun-tracing photoreceptor, see Fig. 6, the shade of light-sensitive surface baffle plate 3 covers photoresistance 1 just, and photoresistance this moment does not trigger.
When sunray and light-sensitive surface out of plumb and when being positioned at the shell central plane near window one side, top flap 3 can reduce in shell bottom plate shadow region 2, sees Fig. 7, make photoresistance 1 be positioned at the solar radiation district, the resistance of photoresistance this moment reduces, if switch 14 closures, relay coil J obtains.
During use, sun-tracing photoreceptor of the present invention is installed in the central recess on four limits of solar panel, sees Fig. 8 and 9, the light-sensitive surface window 4 of sun-tracing photoreceptor upwards.When motor circuit 12 repeat circuit contact JK and switch 9 closures, power supply 16 gives motor 19 power supplies, and the motor-driven driving mechanism carries out corresponding angular setting, sun-tracing to solar panel.
