Description
Technical field
The invention belongs to the distributed power source technical field, be specifically related to a kind of Mechatronic Systems that is used for protecting solar cell.
Background technology
In recent years, people are increasing to the demand of the energy, and are also more and more higher to requirements of saving energy.Along with the development of power electronic technology, the wind and light complementary road lamp system becomes a reality.Wind and light complementary road lamp has distributed characteristics, and it does not need to consider strict installation site, and the block supply that can be difficult to relate to electrical network.
Costing an arm and a leg of solar panel, and real area is big and approach, and easily is damaged, and need carry out suitable protection to it.The solar panel of installing on street lamp can be subjected to bigger blast, in order to guarantee the work of solar cell energy safety, solar panel is carried out certain protection be necessary.
At above-mentioned problem, the present invention has designed a kind of Mechatronic Systems with protection solar cell trouble free service.By to now literature search, find the reported literature consistent as yet with content of the present invention.
Summary of the invention
The object of the present invention is to provide a kind of have prevent that solar panel in the wind and light complementary road lamp from being damaged the Mechatronic Systems of function by excessive blast.
The Mechatronic Systems that the present invention proposes comprises windmill, coding disk, control loop, motor, solar cell grillage, spring governor motion, generator.Its structured flowchart is seen shown in Figure 1.
Wherein, the rotation of windmill wind-engaging drives generator, makes it produce the current signal that increases with wind speed, and current signal is transferred to control loop.Regulate windmill and the rotation of generator body horizontal direction simultaneously behind the empennage wind-engaging of generator afterbody so that windmill has maximum front face area, coding disk is installed in the cod of generator below, coding disk detects the angle that horizontally rotates of generator body, detects the signal of telecommunication that obtains and exports control loop to.
Control loop comprises air vane blast computing module, wind direction angle computing module, solar panel blast computing module and 4 modules of blast size comparison module; Air vane blast computing module is converted into equivalent wind speed on the wind direction at this moment to the current signal relevant with wind speed that receive by microcontroller.While wind direction angle computing module is converted into corresponding rotation to the signal of telecommunication relevant with wind direction that receives and works as measuring angle.Solar panel blast computing module calculates above-mentioned two equivalents by microcontroller, and result of calculation is the equivalent value of the suffered blast of solar panel.Blast size comparison module compares the result of calculation and the predefined equivalent threshold value of solar panel blast computing module; If result of calculation is greater than preset threshold, then output makes motor from normal operation position, is designated as A, rotates to the emergency position, is designated as B.When motor is in emergency position B, the microcontroller clock is set, if the suffered blast equivalent value of solar panel continues a few hours (such as being set at 3～6 hours) less than threshold value, the reverse rotation of control loop control motor from position B to position A.
The spring governor motion of the present invention design by: guide groove, pulley, bearing pedestal and bearing, fixed frame, electromagnetism clamp device, spring, swinging guide rails and push rod are formed.The solar cell grillage is connected by journal bearing with fixed frame, and motor stator is fixed on the fixed frame, and swinging guide rails lower end and motor arbor connect by shaft coupling, and swinging guide rails can be swung between two positions of A, B.Respectively put two baffle plates and electromagnetism automatic clamping device at position A and position B, when switching on to it, this clamp device cancellation clamper.Swinging guide rails is the hollow tube-shape guide rail, and spring one end is fixed in the swinging guide rails lower end, is installed in the guide rail, and the spring other end is fixed in the bottom of push rod, and push rod can slide in swinging guide rails.Pulley is installed on the upper end of push rod, and this pulley can slide in the guide groove under being fixed in the solar cell grillage.
The suffered blast of solar panel calculates according to the suffered blast of blower fan in system of the present invention, adjusts the direction of facining the wind of solar panel after blast surpasses the threshold value that sets by motor, reduces front face area.For avoiding the blower fan response speed slow, adopt the spring governor motion simultaneously, prevent that instantaneous maximum wind pressure phenomenon from producing.
System of the present invention, is measured wind direction by coding disk the sampling of wind speed size by wind-driven generator, and after the signal that obtains was handled by control loop, control system was controlled motor, made the motor rotation to change the suffered blast of solar panel.Spring governor motion of the present invention makes the solar cell grillage in the mechanism change angle by the principle of spring stress distortion.
Fan blade wind-engaging rotation among the present invention drives the wind-driven generator rotation, and the wind-driven generator rotary speed changes with the wind-force size variation.The size of current of wind-driven generator output changes with the variation of generator rotary speed.The signal of wind-driven generator output is transferred in the control loop.Coding disk among the present invention is installed under the wind-driven generator, is used to measure the angle that horizontally rotates of wind power generation body, thereby measures wind direction at that time.
Control method in the control loop of the present invention has mainly comprised: the calculating of blade blast, wind direction angle calculation, solar panel blast calculate, the blast size relatively waits 4 modules.Because the setting angle of solar panel and area thereof all are that when design is known, so just can calculate the facing the wind blast of direction of solar panel by blade blast result calculated and wind direction angle result calculated.If this blast is greater than the safe blast scope of solar panel, control loop just sends the order that changes the solar cell grillage to system.
The spring governor motion of the present invention's design has the effect of buffering strong wind blast, protection solar panel.Under long-time strong wind pressure condition, the rotation of control loop control motor, motor drives the swinging guide rails swing by shaft coupling, the quadric chain transmission of forming by fixed frame, swinging guide rails, push rod, solar cell grillage guide groove, solar cell grillage reduces the angle of facining the wind of solar panel, reduces suffered wind pressure.If wind speed at a time between in the section wind speed change fast and the solar panel blast that facings the wind on the direction excessive, the blower fan response speed may occur and cause the control system response speed slow slowly.At this moment; spring stress in the spring governor motion changes quadric chain: the relative position of a parts in fixed frame and swinging guide rails, push rod, solar cell grillage guide groove, the solar cell grillage; instantaneous big blast is cushioned the protection solar panel to the damage that solar panel causes.
