Fig. 2 is the structural representation of level and luffing mechanism;
Fig. 3 is the circuit diagram of signal processing unit.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
Embodiment: a kind of automatic sun-tracing system of solar panel, as shown in Figure 1, comprise PLC1, PLC1 is connected with relay control module 2, relay control module is also called control relay circuit, by this module, the order of PLC is become electricity order and send to drive unit, this module belongs to the circuit of this area routine, does not therefore repeat them here.Relay control module 2 is connected with drive motor 3, and the output terminal of drive motor 3 is connected with level and luffing mechanism 4, and level and luffing mechanism 4 are connected with solar panel 5; Described PLC1 is also connected with signal processing unit 6, signal processing unit 6 is connected with solar tracking tracking transducer 7, solar tracking tracking transducer is used for detecting sunshine angle in real time, again this Detection Information is sent to signal processing unit in real time, signal processing unit transfers to PLC by after Detection Information process, and PLC carries out rotation according to this information to solar panel and controls.As shown in Figure 2, described drive motor 3 comprises horizontal drive motor 8 and pitching drive motor 9; Described level and luffing mechanism 4 comprise the base 10 be fixed on platform 9, base 10 is fixed with the horizontal drive motor 11 vertically arranged, support 12 is provided with above horizontal drive motor 11, support 12 is provided with the pitching drive motor 13 of horizontally set, and the output terminal of pitching drive motor 13 is provided with solar panel 5.Described PLC1 is also connected with upper PC 14.
The utility model is the double-shaft solar automatic sun-tracing system that a kind of PLC controls, can not only automatically according to sunshine direction adjust solar panel towards, structure is simple, cost is low, and in tracing process can automatic Memory and corrigendum different time coordinate position, need not manual intervention, effectively improve the utilization factor of sun power.System adopts depending on the combined tracking method that day follows the tracks of and photoelectric tracking two kinds of tracking modes combine, and when solar radiation light reaches certain threshold values, first by looking daily motion track following, then adopts solar tracking tracking transducer tracking correction.Improve sensitivity and the degree of accuracy of sun power automatic sun-tracing system.System is made up of PC, PLC, solar panel, solar tracking tracking transducer, signal processing unit, relay control module, level and luffing mechanism and driven by servomotor unit etc.The signal processing unit specialized designs of the system regulating circuit (as shown in Figure 3) of solar tracking tracking transducer, R1, R2, R5 are resistance, and R4 is adjustable resistance, and the collector of triode connects the coil of auxiliary reclay.When there being illumination to be mapped to sensor, photoresistance resistance reduces, once the resistance more default than adjustable resistance is little, through amplifier by triode ON, the coil of auxiliary reclay obtains electric, and normally open contact adhesive comes to PLC signal with this.The driven by servomotor unit of system take DSP as control core, is controlled, can realize stepless time adjustment and the hi-Fix in horizontal and vertical direction by position, speed and moment three kinds of modes to motor.Service system is furnished with automatic protection circuit, automatically starts when wind-force reaches 8 grades, cuts off and follows the tracks of solar system, battery array is closed flat fast, when wind-force lowers, removes Windproof system, recovers tracing process.System realizes telecommunication by RS232, RS422 and RS485, and owing to have employed RS422 interface, take balanced type to send, therefore data transmission rate is high, and crosstalk is little.Especially the tracker of series-parallel grid-connected photovoltaic solar battery array is controlled, the advantage of PLC Fieldbus Control can be played, carry out centralized control.System is monitored by PC, can show the setting of the solar tracking system be stored in PLC internal memory, and the amendment to these optimum configurations.
