two-degree-of-freedom platform driven by a DC brush motor. The two motors used in this platform need the same voltage, and the total current is not more than 6A between 12 and 24V.

The controller is divided into four parts:

I. Testing Head Components

The detection head is composed of a cross-shaped structure with a transparent shell. Its key components are four-quadrant dropping silicone sheet, inverted trapezoidal central column, fixed screw rod, 2-meter long five-core signal line, etc. The central column is made of aluminium and the screw parts are 304 stainless steel. The end of the reverse welding line and the solder joints of the drip plywood are covered with waterproof silica gel. It can be used in various adverse conditions and its service life is not less than 10 years.
The detection head is as follows, with a specially designed transparent shell, waterproof, dust-proof and acid rain-proof. Silicon crystal detection is sensitive to sunlight and can accurately judge cloudy and sunny days.

 

2. Control box.
The control box adopts a waterproof shell with transparent upper cover, and has a circuit composed of MCU, LCD and other components. The five-core signal introduced by the detection head is judged by the built-in program of the circuit. According to the corresponding situation, the corresponding driving execution is made. Its interfaces are the five-core signal of the detection head, the signal of wind speed sensor, wireless remote control signal, power input and the output of east-west axis motor. North-South axis motor output, etc.

3. Remote control.

4. Wind speed sensor
The function of the wind speed sensor is to detect the ambient wind speed. When the wind speed is greater than a certain value, the controller can drive the device flat to minimize the damage of the wind to the device. The wind speed sensor adopts a three-cup rotating structure. Under the action of transverse wind in any direction, it can generate rotation. According to the different wind force, its rotating speed is also different, thus generating different voltage signals. The control box makes wind judgment based on this voltage signal.

The basic principle and installation method of the controller are as follows:

The controller adopts the closed-loop control mode of detection head-controller-axis motor, which is installed on the upper plane of the platform to detect the sun's azimuth in real time. The controller analyses the azimuth and drives the corresponding axis motor to move. As the platform moves, the position of the detection head also moves, and the azimuth voltage output of the controller changes in real time until it aligns with the sun. Closed-loop formation, the controller stops output.

The main logic of the procedure:
After power-on, check the sunshine intensity. If the sunshine intensity is enough, the control platform will aim at the sun. If the sunshine intensity is insufficient, it will delay for a certain time, and the driving device will perform the homing action (which can be done by setting T9/10/11/12).

When the wind speed is detected to exceed a certain value, the driving device performs a specified action (which can be performed by setting T3/4/5/6).

When the Sun runs in the northern hemisphere for a few days in summer, the device can start a specified action at noon, so that it can continue to track in the afternoon. (This action can be done by setting T14/15)

When the manual function starts, the platform unconditionally accepts manual control.

Each function parameter can be set by itself. Human-computer interaction is completed by remote controller and LCD screen.
Installation and debugging method:

Firstly, the detection head should be installed on the north side of the upper platform. The angle range of the East and West axes of the platform should be within 180 degrees, and the angle of the north and South axes should be within 80 degrees. It is recommended that the position from north to head should be exactly flattened. Limitation should be done well in east, west, north and south. The connection method of common limit switch can be referred to after the instruction.

When the detection head is fixed on the platform, attention should be paid to the direction marking of the detection head corresponding to the direction when the platform is flat and centered. The detection head line is fixed slightly, leaving some room. Then, the main control box is fixed in the non-mobile position of the platform. It is better to pay attention to the place where the sun does not shine on the rainwater and the outlet hole is facing down.

The corresponding axle motor line is connected to the corresponding terminal in the controller.

Put the correct DC voltage on the main control box.

(Infrared remote control can turn on or off the backlight by pressing QUIT key for more than 5 seconds)

No matter what state the controller is in, press the SET key of the remote controller once, that is, enter the manual control state. Press the corresponding remote control button ///at this time, the controller will move east/west/south/north, and the display screen will display E/W/S/N. If the direction of movement does not correspond to the description in the manual, the corresponding wiring will be changed until it is consistent with the description in the manual.

Press the QUIT key of the remote controller to exit the manual state and the controller enters the automatic state. At this time, there are several possibilities as follows:

Scenario 1:  If the sunshine value detected in any direction of the detection head is higher than V3 value at this time, the control considers that the current weather is sunny and can enter the platform tracking state. The controller drives the platform to move continuously. When the east-west axis or the north-south axis are aligned in advance, the axis stops and enters the delayed waiting state. There is a delayed waiting time for each of the east-west axis and the North-South axis. It can be set freely. TX is the waiting time for the next alignment after aligning the East and West axes, and TY is the north and South axes. The time can be set according to actual needs. The advantage of this delay setup is that it can save energy to avoid frequent actions (when there is a gap between platforms, poor locking may cause frequent actions), and it can ignore some shadow interference (such as the shadow of wires, the shadow of birds flying, etc.).

Situation 2:  When the voltage value detected in any direction of the detection head can not be higher than V3, the controller considers that it is rainy or night, and the ambient light does not have power generation value. At this time, the controller standby, and countdown time T8 delay waiting.
In the countdown of T8 time, if the ambient light exceeds the V3 value and lasts longer than the T13 time, it immediately enters the A situation and enters the normal tracking. If the ambient light continues to fall below the V3 value and completes the T8 delay, the controller considers that it is indeed rainy or rainy day or night, it will perform the specified actions of the platform. The operation sequence is as follows: First, the T9 time driven eastward and northward are executed. Drive T11 time, stop for one second after the end, then execute West T10 time and South T12 time. These time can be set reasonably to drive the platform to the desired position. After the middle action is executed, it enters the weak waiting state of sunshine. If sunshine appears, it delays T13 time to enter automatic tracking.
Situation 3:  When the controller detects that the wind speed exceeds the V2 value, the controller thinks that the current wind speed may damage the platform, and it is necessary to put the platform in the middle immediately to reduce the damage of the wind. At this time, the controller executes the specified actions: first, the time to drive T3 eastward and T5 northward, then stop for one second, then the time to drive T4 westward and T6 southward. These times can be set reasonably to drive the platform to the position you need. After execution, enter T7 time: T7 is the lock holding time, in this time, if the wind speed restores below V2 value, then T7 time ends, exit to the previous state, if the wind speed is still higher than V2 value in T7 time, then maintain this lock state, until T7 is below V2, then start to exit after countdown.

Situation 4:  In summer, in some latitudes, the sun will cross the North-South middle line and run in the North sky. For the angle of some platforms, there may be a phenomenon that can not be tracked at noon. This controller has the function of automatic flip, which can effectively overcome this shortcoming. Its operation principle is that when this state occurs, the specified action is performed: control the platform to East T14 time. After stopping for one second, the execution platform will take time to West T15 (it is best to set this parameter reasonably and place the platform slightly west of the center).

Parametric and symbolic descriptions:

AT: Automatic tracking state, in which the device automatically tracks the sun

TX: When the East and West axes are aligned, the device will not move during the waiting period.

TY: When the north-south axis is aligned and the state is automatically tracked, the device will not move during the waiting period.

E: East W: West S: South N: North (the indicator moves in the corresponding direction)

FS: The wind speed exceeds the set value and enters the neutral state when it meets the wind.

F: Real-time wind speed and voltage in V.

G: The total value of silicon wafer voltage in the first four directions for reference to the current total sunshine intensity

MT: Manual operation state, in which the remote control 1/2/3/4 keys correspond to the north/south/west/east to move manually.

SL: Weak sunshine, on behalf of the current controller that the sun is weak, will soon enter a dormant state waiting for sunshine to reappear  

SL WAIT: Entering the Weak Hibernation of Sunlight

T8: Accumulative Time of Weak Sunshine

T3: Time value of the device driving eastward when performing specified action of exceeding the wind speed limit

T4: When performing the specified action of exceeding the wind speed limit, the time value of driving device to the west after accepting T3 time

T5: Time value of device driving northward when performing specified action of exceeding wind speed limit

T6: When performing the specified action of exceeding the wind speed limit, the time value of driving device heading south after accepting T5 time

T7: After the specified action of wind speed exceeding the limit, the self-locking time of the controller is designed to prevent the effect of wind speed from being intermittent, which causes frequent action/tracking of the device. In the self-locking time, if the wind speed exceeds the value again, the time is immediately recounted so that the device will not operate frequently.

T8: Delay value of weak duration of sunlight

T9: Time value of eastward drive of the device when performing specified action with weak sunlight

T10: When performing the specified action of weak sunlight, the time value of driving device to the west after accepting T9 time

T11: Time value of northward drive of the device when performing specified action with weak sunlight

T12: When performing the specified action of weak sunlight, the time value of driving device heading south after taking T11 time

T13: The set value of the time delay for the recovery of sunlight after the occurrence of the weak state of sunlight

T14: When the reversal function of the Northern Hemisphere is activated, the device performs specified actions and drives eastward.

T15: When the reversal function of the Northern Hemisphere is activated, the device performs the specified action and drives the time value westward after taking on T14 time.

V1: Tracking accuracy settings, the value is to set the tracking accuracy interval voltage value, that is, when the East/West and South/North silicon wafer voltage values are different how many V, the controller thinks that mobile devices are needed or aimed at the sun, the smaller the value is, the higher the accuracy is, and vice versa, the lower the precision is, which needs to be set according to the characteristics of the platform.

V2: Wind speed start-up voltage value, which is the threshold value of wind speed start-up set by the controller. When the output voltage of the wind speed sensor is higher than this value, the controller thinks that it is necessary to specify actions immediately to protect the platform.

V3: Sunshine weak start-up voltage value, which is the weak threshold value of sunshine set by the controller. When the voltage value of silicon wafer in the first four directions of detection is no higher than this value, the controller considers that the current sunshine is weak, there is no power generation value, cancels the tracking, and delays T8 time if the sunshine has not been restored, then performs the specified action.

X0: On-line correction cardinality of east-west axis angle, because the performance of silicon wafers in the four directions of the detection head can not be completely consistent, increasing this correction cardinality enables the controller to correct the component difference of the detection head, and the device can more accurately align with the sun. The method of setting parameters is explained in detail later.

Y0: North-South axis angle online correction cardinality, the same principle as X0

SUMMER: The Northern Hemisphere Sun Reversal function is activated.

Auxiliary Tips Reference:

1. The backlight of LCD display can be controlled to extinguish without operation to save power. The contrast of LCD screen should not be disturbed, so as not to misadjust the contrast to the lowest level, which is supposed to be a display failure.

2. TX values can generally be set to more than 120 seconds, because the sun moves slowly, about four minutes before moving once.

3. The value of TY can be set to about 100 seconds according to the situation.

4.T3/4/5/6 value, according to the moving speed of the platform, conceive what attitude the platform should move in the case of wind resistance, and then set the corresponding time parameters, which is generally the implementation of leveling, that is, driving northward to the end.

5.T7 is the self-locking delay time after leveling in the wind. The time value can be set a little longer to avoid frequent action of intermittent wind-driven devices. Generally, 600 seconds is the appropriate time.

6.T8 is the delay time of weak sunshine, which is used to calculate the duration of weak sunshine. This value should be set a little longer, so as not to cause frequent movement of the platform due to short rainy time. This time should be more than 1200 seconds.

7.T9/10/11/12 is the time for executing the prescribed action when the sun is weak. According to the moving speed of the platform, the author conceives how to move to an appropriate position. It is suggested that the east-west axis should be in the middle of the north-south axis to be flattened. That is to say, a certain time should be taken eastward to confirm that the time can end, and then half of the whole journey west-east. The north-south proposal is flattened because the night time is longer and flattening is beneficial to avoiding the wind. If during the day, in case the sun is temporarily lost, flattening is also conducive to the capture of the sun when it reappears.

8.V1 is the tracking accuracy setting, usually between 0.00 and 0.15. According to the accuracy and tracking effect of the platform, 0.01 is recommended.

9.V2 is the starting voltage of wind speed. The default wind speed sensor is set at 0.1V. Users can adjust it by themselves. If they use other wind speed sensors, they must use voltage type wind speed sensors. The parameters are set by themselves according to their specifications. The method of fuzzy setting is to observe the F = when they feel that the wind in the environment at that time may damage the platform. On the basis of a little lower settings can be. For example, if F = 0.30V at that time, it would be reasonable to set the threshold V2 to 0.25.

10.V3 is the threshold of weak sunlight. It is recommended to set it reasonably between 1.5V and 1.8V.

The setting of 11.X0/Y 0 depends on the error of the detection head. If there is no special requirement for accuracy, it can be set to 1.0.

12. The M6 bolt is used to fix the azimuth detection head. You need to open an M6.1 hole on the north side of the platform to fix the detection head.

13. The installation hole size of the main control box is: four M6 holes, left and right spacing 18.2CM, upper and lower spacing 5.1CM.

14. The installation hole size of the wind speed sensor is: two M6 holes with 5.6CM spacing. The maximum diameter of placement is 25CM.
