Description of drawings
Accompanying drawing 1 is the structural representation that the photovoltaic plant based on solar panel and neuroid of the present utility model patrols day sensing and controlling device;
Accompanying drawing 2-4 is that the photovoltaic plant based on solar panel and neuroid of the present utility model patrols day sensing and controlling device horizontal direction from the schematic diagram of motion tracking.
Embodiment
Below in conjunction with embodiment and accompanying drawing the photovoltaic plant based on solar panel and neuroid of the present utility model being patrolled a day sensing and controlling device is described in detail; thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
Photovoltaic plant based on solar panel and neuroid of the present utility model patrols day sensing and controlling device and mainly is comprised of solar direction collector and controller, as shown in Figure 1, wherein the solar direction collector comprises two groups of cross one another solar photovoltaic cell panels 1, transparent material case 2, shutter 3.
Horizontal direction from motion tracking with identical with the automatic following principle of vertical direction, take horizontal direction as example, shown in accompanying drawing 2-4, this device is comprised of left and right sides photoelectric cell, controller and motor three parts, four photoelectric cells are installed on the photovoltaic in a certain angle, with its synchronous operation, when light source direction during over against sun tracing apparatus, the voltage difference (V1:V2) of being set the photoelectric cell output of the solar direction collector left and right sides by controller is initial value, not conducting of control circuit in this Time Controller, device is in halted state.In a single day the solar source direction changes, then photoelectric cell output voltage in the left and right sides produces difference (V1:V2), export corresponding signal after relatively amplifying through circuit in the controller: when the right light intensity during greater than the left side, be V1:V2〉during the preliminary examination value, driving circuit 1 conducting in the controller, motor clockwise rotates, and the drive system turns right; When left side light intensity during greater than the right, right photoelectric cell receives stronger light, during V1:V2＜preliminary examination value, and driving circuit 2 conductings, motor rotates counterclockwise, and the drive system turns right.Be light source in the horizontal direction during the vertical incidence photovoltaic panel when left and right sides photoelectric cell no-voltage is poor, driving circuit 1 and driving circuit 2 not conductings in the controller, motor stops operating, and this moment, horizontal direction reached optimized incidence.The up and down photoelectric cell of horizontal direction is accepted light source and is produced voltage difference, drive motor clockwise rotates and rotates counterclockwise respectively after relatively amplifying, thereby regulate the angle of inclination of photovoltaic panel horizontal direction, when horizontal direction reached optimized incidence, motor stopped operating.
When solar direction collector horizontal direction during over against sunshine, shadow shield overlaps with sunshine light and is 0 degree, and shadow-free produces; When there are angle in horizontal direction and sunshine light, sunshine will produce shade by shadow shield, and the photovoltaic panel output voltage of shadow side is diminished, and the photovoltaic panel output voltage of shadow-free side is constant, thereby in a disguised form increase both sides photovoltaic battery panel output voltage ratio, namely increase sensitivity.
In the controller with the duration of runs and the parameter regulating command of the chip of ANN (Artificial Neural Network) Control program record certain hour motor and learnt, the ANN (Artificial Neural Network) Control program is comprised of input layer, hidden layer and output layer, every one deck includes several neurons, and j neuron has following input/output relation in the k layer:
yj(k)=fj(k)(∑Wij(k-1)yi(k-1)-Rj(k))
J=1 wherein, 2 ..., Nk; K=1,2 ..., M
Wij in the formula (k-1) be in (k-1) layer i neuron to the individual neuronic strength of joint of k layer j; Rj (k) is corresponding neuronic threshold values; Fj (k) is neuronic transport function; Nk is the neuronic number of k layer; M represents total number of plies.
In the control system, with the opening time of a BP ANN (Artificial Neural Network) Control motor, input layer input several months, several days, what day, what time, output layer is exported the opening time of each motor; With the running speed of another BP ANN (Artificial Neural Network) Control motor, input layer input several months, several days, what day and average velocity, output layer is exported the running speed of each motor.With dynamic front 4 day data as learning sample by artificial neural network learning, thereby calculate opening time of each motor on the same day and shut-in time, speed.
After controller finds that the variation range of opening time of each motor on the same day and shut-in time, speed surpasses variation range a few days ago and exceeds specialized range numerical value, controller identifies this tracker and breaks down, to automatically cut off the signal controlling of solar direction collector, use Neuro Controller instead and control according to speed and the angle variation range of the study of days past.
This device both can have been set according to artificial neural network running speed, opening time and the shut-in time changing value of each motor every day, also can be according to running speed, opening time and the shut-in time of administrative center's needs free setting each motor every day.
This patrols time, velocity variations or difference that day tracker adopts neuroid algorithm self-teaching daily run, when the running angle difference surpassed the mean change scope of the past period, system's automatic adjustment system was got back to normal range or is made corresponding failure warning by controller.
The neuroid algorithm departs from solar source with the resultful large error of electricity generation system when error occurs the low profile photovoltaic plate of avoiding.
Above-described embodiment limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in the protection domain of the present utility model
