Background technology

At present, the dynamic power machine of operation is mainly traditional internal combustion engine tractor, its work in China's warmhouse booth When to there is energy transformation ratio low, the problems such as seriously polluted.With work in the lifting of oil price, warmhouse booth The cost of industry also gradually increases.Solar energy belongs to clean energy resource, and environmental protection is inexhaustible.To solar energy Direct utilization, started the new height of human development, be conducive to social sustainable development.Therefore, develop A kind of miniature crawler tractor with solar energy as power is particularly useful.Although China has issued for one A little greenhouse miniature electric tractors and solar automobile, but generally existing uninterrupted working time is limited, travel road Journey is short, solar panel is fixed, take can limited efficacy the problems such as, fail the bigger miniature shoe in performance greenhouse Performance with tractor.

The content of the invention

It is an object of the invention to provide a kind of miniature crawler tractor of solar energy greenhouse, when sunny, Electrical energy drive crawler tractor is directly provided with solar panel to advance and charge for battery；Work as sunlight When not enough, electrical energy drive crawler tractor is provided jointly with battery and solar panel and is advanced；When not having During sunlight, only provide electrical energy drive crawler tractor with battery and advance, and when continuous rainy weather, It is equipped with emergent charging power supply.And the solar panel can be carried out according to the power of illumination to its orientation Adjust automatically, so as to improve the operating efficiency of cell panel.

In order to realize the purpose, the present invention is adopted the following technical scheme that and is achieved：

Specific embodiment

Solar panel automatic light tracking with reference to Fig. 2, at the top of the miniature crawler tractor of the solar energy greenhouse System mainly includes：STC89C54, solar panel, PSD sensors, stepper motor, stepper motor Driver, Twin-shaft machinery support.

When solar irradiation is mapped on solar panel, PSD is able to detect that produced on solar panel Electric current, by electric current feeding STC89C54 single-chip microcomputers carry out analog-to-digital conversion, the position of the sun is judged by single-chip microcomputer, Then controlled quentity controlled variable is sent to control the rotation of Twin-shaft machinery support with Driving Stepping Motor to stepper motor driver, with The deflection and the angle of pitch of adjustment solar panel, so that solar panel is vertical with sunray, Solar panel is set to receive solar energy to greatest extent.

With reference to Fig. 3, the mechanical part of the light tracing system includes：Solar panel, T-shaped support, cam, Connecting rod, turbine and worm decelerator and 2 motor compositions, visit on the solar panel with PSD Survey device.

The solar panel automatic light tracking system is passed through using double-axis tracking method, i.e. solar panel Change the deflection and the angle of pitch of system around the action of vertical axes and trunnion axis independence.When single-chip microcomputer spreads out of control After signal processed, stepper motor A Jing worm type of reduction gearings drive T-shaped support to realize that horizontal direction is rotated, i.e., just The adjustment of parallactic angle.And stepper motor B drives cam mechanism that the adjustment of the angle of pitch is realized by universal coupling.It is logical Cross the control to stepper motor, it is possible to reach the control to follower travel direction angle and the angle of pitch, from And make solar panel vertical with sunray.

With reference to Fig. 4,5,6, charging circuit includes：Diode, solar panel, the storage of exportable 12V Battery.

When sunny, when making the voltage that solar panel is produced more than 12V, Fig. 4 circuit turn-ons, now Solar panels electric energy directly for needed for car offer, meanwhile, solar panel is battery charging.

When sunlight is not enough, when making the voltage that solar panel is produced be less than 12V, with solar cell in Fig. 5 The diode cathode voltage of plate series connection is higher than positive pole, and solar panel no longer conveys electric energy, therefore only stores Battery provides electric energy, and solar panel provides circuit in the circuit of the right, realizes providing electric energy simultaneously.

When not having sunlight, the circuit in Fig. 6 directly provides required electric energy by battery, and be connected with should Boost charge power supply, in case continuously overcast and rainy cause equipment to work in time.
