<Embodiment 1>
FIG. 1 is a rear external perspective view showing an outline of the configuration of the tracking drive solar power generation apparatus according to Embodiment 1 of the present invention.

  The tracking drive type photovoltaic power generation apparatus 1 according to the present embodiment receives solar light by rotating solar cell panel 2 that receives sunlight to generate power, and solar cell panel 2 in a direction perpendicular to sunlight. A tracking drive unit 3 for tracking, a support column 4 for mounting and fixing the tracking drive unit 3, and a drive control unit 5 for generating a tracking drive signal for driving and controlling the tracking drive unit 3 and outputting the tracking drive signal to the tracking drive unit 3. I have.

  The tracking drive unit 3 to which the solar battery panel 2 is attached constitutes a rotating mechanism drive system that tracks the movement of the sun (solar trajectory), and tilts with the worm speed reducer 6 that drives (controls) the turning in the horizontal direction. The power cylinder 7 which drives (controls) is provided.

  In other words, the solar cell panel 2 is tilted and rotated to control the tilt corresponding to the solar altitude (h) in order to track the solar orbit at the installation location (the surface of the solar cell panel 2 is always oriented perpendicular to the sun). This is a configuration (rotation mechanism drive system) in which drive control is performed by a two-axis drive composed of the axis AXi and the rotation axis AXr that controls the rotation corresponding to the sun azimuth angle (ψ) (see FIG. 5).

  The drive control unit 5 generates a turning and tilting control signal corresponding to the solar orbit (orbit value) as a tracking drive signal (tracking drive power) from the installation location (latitude, longitude) and date and time, and sends it to the tracking drive unit 3. Output. The support column 4 is composed of a pipe line (steel pipe) having sufficient strength to support the solar cell panel 2 and the tracking drive unit 3. The tracking drive unit 3 and the drive control unit 5 are connected to each other by a cable wired in the pipe line of the column 4.

  2 and 3 are explanatory diagrams conceptually showing an installation procedure of the tracking drive type solar power generation apparatus shown in FIG.

  First, the support column 4 is firmly installed with accuracy in the vertical direction (vertical direction) on the ground GND or the like on which the foundation work has been performed (FIG. 2A). Note that a flange surface (top surface of the support column 4) 4a, which becomes an installation reference surface (reference surface of the rotation mechanism drive system), is formed in advance at the tip of the support column 4.

  Next, the tracking drive unit 3 is aligned with the flange surface 4a of the support column 4 and fastened firmly (FIGS. 2B and 2C). The tracking drive unit 3 includes a drive unit base 3a that serves as a base of a rotation mechanism drive system. The base bottom surface 3b, which is the bottom surface of the drive unit base 3a, is in contact with the flange surface 4a and constitutes a reference surface of the rotation mechanism drive system together with the flange surface 4a. Therefore, the flange surface 4a supports the tracking drive unit 3 (base bottom surface 3b) over the entire surface.

  As described above, since the flange surface 4a serves as a reference surface for installation (reference surface of the rotation mechanism drive system), the levelness (inclination with respect to the horizontal plane) is important. That is, even if the inclination deviation is measured and adjusted on the panel surface of the solar cell panel 2 after the solar cell panel 2 is attached, the deviation of the panel surface is caused by the deflection / twist of the solar cell panel 2 itself, the tracking of the solar cell panel 2 and the like. Since it includes a combined form such as a displacement due to the fastening of the drive unit 3, it does not correct the “deviation” of the rotation axis AXr and the tilt rotation axis AXi with respect to the reference surface (reference surface of the rotation mechanism drive system). .

  Therefore, in order to suppress the tracking drive shift due to the mounting shift (azimuth shift, inclination) of the support column 4 and perform accurate tracking, the mounting state of the flange surface 4a is accurately measured and the correction according to the mounting state is performed. (See FIG. 14) is important.

  Next, the solar cell panel 2 is attached to the tracking drive unit 3, and the gantry construction process is completed (FIG. 2C, FIG. 3).

  Then, the drive control part 5 is installed, the cable wiring which mutually connects the tracking drive part 3 and the drive control part 5 is performed, and the tracking drive solar power generation device 1 is completed (FIG. 3).

  4A and 4B are outline views schematically showing the external appearance of the tracking drive unit of the tracking drive type solar power generation apparatus shown in FIG. 1, where FIG. 4A is a side view and FIG. 4B is a front view of the bottom surface of the base. It is.

  The tracking drive unit 3 includes a power distribution unit 8 including a power distribution board for distributing and supplying the tracking drive power from the drive control unit 5 to the worm reducer 6 and the power cylinder 7, and a drive mechanism unit 9 constituting a rotation mechanism drive system. (Figure (A)). Further, on the drive unit base 3a (base bottom surface 3b), fastening bolt holes 3c for fastening and fixing the tracking drive unit 3 to the flange surface 4a are formed in eight equal parts (the same figure ( B)).

  FIG. 5 is an explanatory diagram conceptually showing the rotation mechanism drive system of the tracking drive unit of FIG.

  The rotation mechanism drive system of the tracking drive unit 3 is configured to be able to perform drive control by two-axis drive of a turning rotation axis AXr that controls turning in the horizontal direction and a tilting rotation axis AXi that controls tilting in the vertical direction. It is. As described above, the turning rotation axis AXr is controlled corresponding to the worm speed reducer 6, and the tilting rotation axis AXi is controlled corresponding to the power cylinder 7.

  Since the tracking drive unit 3 is fixed to the flange surface 4a, the tilt rotation axis AXi (tilt rotation reference axis) and the turning rotation axis AXr (turning rotation reference axis) are fixed to the reference surface (flange surface 4a), respectively. Thus, the reference plane deviation (azimuth deviation and inclination) becomes the reference position deviation (rotation axis deviation) of the tilt rotation axis AXi and the turning rotation axis AXr. Therefore, it is possible to correct the deviation of the tilt rotation axis AXi and the turning rotation axis AXr by measuring and correcting the deviation of the reference plane (see FIG. 14).

<Embodiment 2>
FIG. 6: is an external view explaining the jig base which comprises the solar power generation device installation jig which concerns on Embodiment 2 of this invention, (A) is a top view of a jig base, (B) Is a side view of the jig base and the flange surface (support) facing each other, and (C) is a front view of the flange surface.

  The jig base 10 constitutes a basic structure of a solar power generation apparatus installation jig (hereinafter referred to as an installation jig). On the surface of the jig base 10, there is formed a cross groove 10a into which the instrument angle base 11 (see FIGS. 7 to 9) is fitted (held). The cross groove 10a is located between the north, south, and east and west. Right-angle accuracy is set so that positioning can be performed ((A) in the figure).

  The back surface of the jig base 10 is formed with a recess 10b that can come into contact with the flange surface 4a so as to surround the outer periphery of the flange surface 4a of the support column 4. The jig base 10 can be azimuthally aligned (positioned) by sliding and rotating (surface (B)).

  On the outer periphery of the flange surface 4a, there are eight flange holes 4b for fastening so that the drive unit base 3a (tracking drive unit 3) can be fastened and fixed (see FIG. 2) by contacting the base bottom surface 3b. (Fig. 3C). That is, the fastening flange hole 4b is formed to face the fastening bolt hole 3c on a one-to-one basis.

  The jig base 10 (cross groove 10a) has base fixing screw holes 10c (north-north / east-west) so as to correspond to the eight fastening flange holes 4b (fastening bolt holes 3c). 4). The base fixing screw hole 10c is formed so as to penetrate the jig base 10 so as to be fixed to the flange surface 4a by a positioning pin 10ca (see FIG. 10).

  In addition, since the screw hole 10c for base fixation is comprised as a screw part of the same tap shape as the bolt hole 3c for fastening of the drive part base 3a, the jig base 10 is driven with respect to the flange surface 4a. It can be fastened with the same accuracy as the part base 3a. Therefore, the measurement result of the installation displacement (azimuth misalignment and inclination) of the reference surface (flange surface 4a) obtained by contacting the jig base 10 with the flange surface 4a can be applied to the drive unit base 3a as it is. Is possible.

  Further, the jig base 10 is provided with an inclination adjusting screw 10da (for adjusting the inclination of the jig base 10 (the instrument angle base 11) when measuring with an azimuth meter and an inclinometer described later (see FIG. 11). Inclination adjusting screw holes 10d for screwing together (see FIG. 10) are formed in four equal parts corresponding to the northeast, northwest, southeast, and southwest. The fastening flange hole 4b is a “fool hole” in consideration of fastening workability and the like, and has a slightly larger diameter than the base fixing screw hole 10c.

  In addition, a cable hole (not shown) for passing a cable connected to the drive control unit 5 is provided on the lower side surface of the support column 4 corresponding to the drive control unit 5 (in one direction), and eight fastenings are provided. The support column 4 is installed and fixed so that the hole formed in the same direction as the cable hole in the flange hole 4b for the direction faces the substantially north direction.

  7A and 7B are external views of an instrument angle base (Example 1) that constitutes an installation jig according to Embodiment 2 of the present invention, where FIG. 7A is a plan view and FIG. 7B is a side view.

  In this embodiment, the instrument angle base 11 is configured in a cross shape so as to be fitted in the cross groove 10 a of the jig base 10. Two inclinometers 12 are mounted on adjacent angle branches of the instrument angle base 11 so as to be orthogonal to each other corresponding to the north-south and east-west directions. An azimuth meter 13 is placed at the center of the instrument angle base 11.

  With the instrument angle base 11 fitted in the cross groove 10 a of the jig base 10, the orientation of the instrument angle base 11 is measured using the compass 13, so that the installed column 4 (flange surface 4 a ) Orientation (azimuth deviation from true north) can be measured. Further, the inclination of the instrument angle base 11 in the north-south and east-west directions, that is, the inclination of the installed support column 4 (flange surface 4a) with respect to the horizontal plane can be measured.

  Since the inclinometer 12 and the azimuth meter 13 are mounted together on the same reference plane (the flange surface 4a of the support column 4), the displacement of the reference plane is simultaneously detected (measured) as described later (see FIG. 11) ). Therefore, it is possible to detect the azimuth (azimuth deviation) and the inclination with higher accuracy, and the installation state (azimuth deviation, inclination) of the reference plane can be measured accurately, quickly and easily.

  Further, by measuring the azimuth and the inclination by changing the fitting direction of the instrument angle base 11 by 90 degrees, it is possible to eliminate the error due to the difference in the mounting state of the inclinometer 12 and the azimuth meter 13.

  In addition, it is also possible to adopt a form in which the inclinometer 12 and the azimuth meter 13 are positioned and placed directly on the jig base 10 without fitting the instrument angle base 11 without providing the cross groove 10a.

  8A and 8B are external views of an instrument angle base (Example 2) that constitutes an installation jig according to Embodiment 2 of the present invention, where FIG. 8A is a plan view and FIG. 8B is a side view.

  In this embodiment, the inclinometer 12 is composed of two units as in the first embodiment. In addition, angle branches that are positioned in a straight line on the cross-shaped instrument angle base 11 are extended in opposite directions so as to protrude from the jig base 10, and GPS (Global Positioning System) antennas 13a are provided at both ends thereof. Are arranged to constitute one compass (13). Hereinafter, the azimuth meter using the antenna 13a is also referred to as a GPS azimuth meter.

  Since the accuracy of the azimuth measured using the GPS azimuth meter depends on the distance between the two GPS antennas 13a, it is desirable to make the distance as long as possible in order to increase the accuracy. According to the instrument angle base 11 of the present embodiment, the interval between the GPS antenna pairs can be made larger, so that more accurate azimuth can be detected.

  In this embodiment, the distance between the GPS antennas 13a is set to 1 m in consideration of portability. With this configuration, the azimuth (azimuth) measurement error can be suppressed to an instantaneous maximum value of 0.5 degrees and an average value (effective value) of about 0.1 degrees.

  Further, by measuring the azimuth and the inclination by changing the fitting direction of the instrument angle base 11 by 90 degrees, it is possible to eliminate the error due to the difference in the mounting state of the inclinometer 12 and the azimuth meter 13.

  Also in the present embodiment, it is possible to detect (measure) the displacement of the reference surface (the flange surface 4a of the support column 4) as in the first embodiment.

  9A and 9B are external views of an instrument angle base (Example 3) constituting the installation jig according to Embodiment 2 of the present invention, where FIG. 9A is a plan view and FIG. 9B is a side view.

  In this embodiment, the instrument angle base 11 is formed in a straight line (one letter shape) so as to be fitted in each direction of the cross groove 10a, and the inclinometer 12 is composed of one unit arranged at the center of the straight line. . Further, as in the case of the second embodiment, the distance between the GPS antennas 13a is long.

  In this embodiment, after measuring the azimuth and the east-west inclination, the instrument angle base 11 is fitted to the groove in the other direction of the cross groove 10a (that is, the instrument angle base 11 is rotated 90 degrees). The same measurement as in Example 1 and Example 2 can be performed by measuring the slope at.

  As shown in FIGS. 7 to 9, the installation jig is a jig base 10, an instrument angle base 11 fitted and placed on the jig base 10, and an inclination relative to a horizontal plane placed on the instrument angle base 11. It is composed of an inclinometer 12 that measures (tilt) and an azimuth meter 13 that is placed on an instrument angle base and measures the azimuth. As described above, the inclinometer 12 and the azimuth meter 13 can be directly mounted on the jig base 10 by omitting the instrument angle base 11.

  Also in the present embodiment, it is possible to detect (measure) an installation shift of the reference surface (the flange surface 4a of the support column 4) as in the first and second embodiments.

  10A and 10B are external views for explaining the usage state of the installation jig according to Embodiment 2 of the present invention, in which FIG. 10A is a plan view and FIG. 10B is a side view transparently showing a main part (positioning pin). FIG.

  A case will be described in which a GPS azimuth meter (azimuth meter 13) using two GPS antennas 13a and an instrument angle base 11 (two examples: FIG. 8) equipped with two inclinometers 12 are used. The same applies to the case where the instrument angle base 11 shown in FIG. 1 (FIG. 7) and Example 3 (FIG. 9) is used.

  The outer peripheral shape of the flange surface 4a is circular, and the fastening bolt holes 4b for fastening and fixing the drive unit base 3a are formed in eight equal distributions along the outer periphery (see FIG. 6C). . Since one of the fastening bolt holes 4b is installed so as to face the substantially north direction when the support column 4 is installed, the fastening bolt hole 4b (the north-south direction) located in the substantially north direction (north-south direction). The jig base 10 is placed on the flange surface 4a in such a way that the base fixing screw holes 10c correspond to the two in the direction. In the figure, for example, the vertical direction corresponds to north-south, and the left-right direction corresponds to east-west.

  As described above (see FIG. 6), the base fixing screw hole 10c is a screw portion having the same tap shape as the fastening bolt hole 3c formed in the drive unit base 3a. On the other hand, since the fastening flange hole 4b is a fool hole slightly larger than the base fixing screw hole 10c, the flange surface 4a (fastening flange hole 4b) is used by using a pair (two, north and south) positioning pins 10ca. ) Is fixed to the jig base 10 (base fixing screw hole 10c). That is, the positioning pin 10ca has a shape having a screw portion having the same tap shape screwed into the base fixing screw hole 10c and a pin portion fitted into the fastening flange hole 4b.

  The inclinometer 12 and GPS azimuth meter (GPS antenna 13a) were placed with the jig base 10 (base fixing screw hole 10c) positioned relative to the flange surface 4a (fastening flange hole 4b). The instrument angle base 11 (attached) is fitted into the cross groove 10 a of the jig base 10.

  The jig base 10 is formed with an inclination adjusting screw hole 10d for adjusting the inclination of the jig base 10 (the instrument angle base 11) with respect to the flange surface 4a. The tilt adjustment screw 10da is screwed into the tilt adjustment screw hole 10d, protrudes from the back surface side (recess 10b) of the jig base 10, and acts on the flange surface 4a, thereby causing the jig base 10 (the angle base for the instrument). The inclination of 11) can be adjusted.

  Therefore, even when the flange surface 4a is inclined with respect to the horizontal plane, the jig base 10 (instrument angle base 11) can be made horizontal, and the jig base 10 (instrument angle base 11). It becomes possible to accurately measure the orientation (measurement of the orientation deviation of the reference plane) by the compass 13 in a state where the is horizontal.

  Further, by measuring the azimuth and the inclination by changing the fitting direction of the instrument angle base 11 by 90 degrees, it is possible to eliminate the error due to the difference in the mounting state of the inclinometer 12 and the azimuth meter 13.

  The positioning pin 10ca is also used when the drive base 3a (fastening bolt hole 3c) is fastened to the flange surface 4a (fastening flange hole 4b) to fix the drive base 3a (fastening bolt). Positioning and fastening between the hole 3c) and the flange surface 4a (fastening flange hole 4b) can be reliably performed.

  That is, by engaging the positioning pin 10ca, which is screwed into two positions (for example, the north-south position) of the drive base 3a (fastening bolt hole 3c), into the fastening flange hole 4b, the drive base 3a and the flange As the state of positioning with respect to the surface 4a (fastening flange hole 4b), the remaining six places where the positioning pins 10ca are not inserted are fastened with bolts inserted from the ground side of the flange surface 4a. Thereafter, the drive base 3a can be fastened and fixed to the flange surface 4a by removing the two positioning pins 10ca and fastening them with bolts.

That is, the positioning pins 10ca are respectively screwed into the two base fixing screw holes 10c arranged (positioned) in the north-south direction (corresponding to the vertical position in FIG. 10) of the jig base 10 from the back side (recess 10). The jig base 10 is brought into contact with the flange surface 4a by fitting the pin portions of the two positioning pins 10ca protruding from the back surface into the two fastening flange holes 4b corresponding to the north-south positions of the flange surface 4a.

  A computer program for performing the following processing flow is preinstalled in the installation computer 21 (see FIG. 12), and the processing content and measurement values (measurement results) are appropriately displayed on the display screen of the installation computer 21. I have to do it.

Step S12:
The instrument angle base 11 on which the inclinometer 12 (two units) and the direction meter 13 are mounted is fitted into the cross groove 10a (mounted on the jig base 10). Both the inclinometer 12 and the azimuth meter 13 are arranged in a state shifted from the true azimuth (for example, the true north direction) corresponding to the azimuth deviation ψ 0 in the installation direction of the support column 4.

Step S14:
In the state as it is (the state of the azimuth deviation ψ 0 in which the jig base 10 is brought into contact with the reference surface), the inclination with respect to the horizontal plane is measured by the inclinometer 12. That is, the inclination α0 in the temporary north-south direction (direction shifted ψ0 from the true north-south direction) by one inclinometer 12 arranged in the north-south direction is changed to the temporary east-west direction (true The inclination β0 in the direction shifted by ψ0 from the east-west direction is measured.

  Since the inclination in the north-south direction and the east-west direction can be obtained in correspondence with the azimuth deviation ψ0, accurate correction parameters for the north-south direction and east-west direction deviation of the rotation mechanism drive system of the two-axis drive can be obtained.

  The measurement by the inclinometer 12 is repeatedly executed at an appropriate measurement cycle, and the measurement value is output to the installation computer 21 through the built-in communication interface each time.

Step S16:
In the state of the azimuth deviation ψ0, the jig base 10 (and the instrument angle base 11) is adjusted to a horizontal state by using the inclination adjustment screw 10da, and the azimuth is measured by the azimuth meter 13. That is, the accurate installation direction (value of the orientation deviation ψ0) of the support column 4 fixed and installed is measured.

  Note that the measurement by the azimuth meter 13 is repeatedly executed at an appropriate measurement cycle, and the measurement value is output to the installation computer 21 each time via a built-in communication interface. Further, the horizontal state can be secured by appropriately adjusting the four tilt adjusting screws 10da so that the indicated values of the two inclinometers 12 are 0 degrees.

Step S18:
The positioning pin 10ca is removed, and the jig base 10 is rotated (rotated) by an angle corresponding to the azimuth deviation ψ0, and the jig base 10 (in the position indicating the true north direction (true north direction) is displayed. And an instrument angle base 11). That is, the jig base 10 (and the instrument angle base 11) is arranged in correspondence with the true north state. The tilt adjustment screw 10da is adjusted as appropriate to maintain the horizontal state of the jig base 10 (and the instrument angle base 11).

Step S20:
The inclination adjusting screw 10da is adjusted to release the horizontal state of the jig base 10 (and the instrument angle base 11), and the inclination with respect to the horizontal plane is measured by the inclinometer 12 in a state where the jig base 10 is in contact with the reference surface. That is, in the true north state, the inclination α in the north-south direction (true north-south direction) and the inclination β in the east-west direction (true east-west direction) are measured.

  Since the inclination in the north-south direction and the east-west direction can be obtained corresponding to the azimuth (true north state), it is possible to obtain an accurate correction parameter for the north-south direction and east-west direction deviation of the rotation mechanism drive system of the biaxial drive. it can.

  Through the above steps S10 to S20, it is possible to easily, accurately and quickly obtain the mounting state (tilt and azimuth misalignment) of the reference surface. That is, the orientation deviation ψ0 of the installed support column 4, the inclination α0 in the temporary north-south direction (azimuth deviation ψ0 state: support installation state), the inclination β0 in the provisional east-west direction (azimuth error ψ0 state: support installation state), true The inclination α in the north-south direction and the inclination β in the true east-west direction can be obtained easily, accurately and quickly.

  Moreover, since these measured values can be taken into the installation computer 21 as data, the measurement efficiency can be greatly improved. Furthermore, highly accurate adjustment work is not required in the installation work, and the efficiency and safety in the installation work can be greatly improved.

  As will be described later, the correction parameter is obtained by easily, accurately and quickly obtaining the azimuth deviation ψ0, inclination α, inclination β (or azimuth deviation ψ0, inclination α0, inclination β0) used as correction parameters (see FIG. 14). Since the azimuth deviation and the solar azimuth deviation hd and the azimuth angle deviation ψd caused by the inclination in the installation state of the support column 4 (flange surface 4a: reference plane) are calculated as correction values, The solar altitude h and the theoretical solar azimuth angle ψ (see FIG. 13) can be corrected.

  FIG. 12 is a block diagram showing blocks constituting the measurement system when the processing flow of FIG. 11 is executed.

  Measurement values (see Steps S14, S16, and S20) by the inclinometer 12 (two units) and the azimuth meter 13 (one unit) that constitute the measurement system independently of each other are for installation via the communication line 19 and the terminal 20 It is repeatedly transmitted (input) to the computer 21 corresponding to the measurement cycle.

  The installation computer 21 appropriately averages the measured values that are repeatedly input and collected at a certain time (for example, about 5 to 10 minutes) to eliminate the variation, and the measurement results (the orientation deviation and the mounting state value of the reference surface) The step of inputting to the drive control unit 5 as (tilt) is executed.

  That is, by averaging the measurement values repeatedly measured within a certain time to obtain an average value (effective value), errors in the measurement system can be eliminated. For example, in the case of a GPS azimuth meter, the azimuth error due to the position of the satellite can be canceled out, so that the measurement error can be effectively suppressed to 0.1 degrees or less.

  Therefore, the installation computer 21 can input (transmit) the accurate azimuth deviation ψ0 and the inclinations α and β (or α0 and β0) to the drive control unit 5 as correction parameters.

  According to this measurement system, measurement data (azimuth deviation, inclination) in each independent measurement system can be measured simultaneously under the same measurement conditions, and the measurement data (measurement value) is directly processed by the installation computer 21. Therefore, it is not necessary to consider the measurement conditions of the measurement data (measurement variations when measuring each data), and measurement data with less errors can be obtained.

  In addition, since all measurement data is directly transmitted and received between devices via a communication interface, there is no possibility of input errors and the correction parameters required for correcting the trajectory calculation by the drive control unit 5 are extremely easy and accurate. Can be sought quickly.

  In particular, when a GPS compass is used, it is possible to measure the orientation in a short time at any point on the earth, and the place where the solar cell panel 2 (tracking drive type solar power generation device 1) is installed is Since it is premised on that there is no building such as a building that serves as a light-shielding body for the solar battery panel 2 in the surroundings, accurate measurement can be reliably performed.

  In addition, by using GPS, it is possible to easily acquire the exact time required for the calculation of the solar orbit at the same time and input it to the drive control unit 5, thereby simplifying the solar cell installation work. Is possible. That is, since the accurate time is acquired, the theoretical solar altitude h and the theoretical solar azimuth angle ψ can be accurately calculated.

  The measurement result (correction parameter) input to the drive control unit 5 is appropriately stored in a memory provided in the drive control unit 5. The drive controller 5 calculates the corrected solar altitude hr and the corrected solar azimuth angle ψr by performing correction based on the correction parameter on the theoretically calculated theoretical solar altitude h and theoretical solar azimuth angle ψ (see FIG. 13). Then, a tracking drive signal is generated based on the calculated corrected solar altitude hr and corrected solar azimuth angle ψr.

  That is, the drive control unit 5 is configured to output a tracking drive signal that has been corrected based on the azimuth deviation and inclination (azimuth deviation ψ0, inclination α, β (or α0, β0)) of the reference plane.

  FIG. 13 is a conceptual diagram showing the relationship between parameters when the solar orbit is represented in the horizontal coordinate system.

  A horizon HL is set at a position where the sphere for representing the position of the sun SUN is equally divided up and down, and north N, east E, south S, and west W are determined as directions corresponding to the horizon HL. The observer O is positioned at the center of the sphere with the top of the sphere as the zenith Zt and the bottom as the nadir Zb. The angle φ formed between the celestial north pole Pn / south pole Ps and the horizon HL corresponds to the latitude φ.

  If the latitude, which is a unique value of the place where the observer O is located, is φ, the solar declination calculated from the date is δ, and the time angle calculated from the south-central time of the place is ω, any time The theoretical solar altitude h and the theoretical solar azimuth angle ψ representing the solar orbit SR can be obtained by calculation (theoretical formula) using the horizon coordinate system.

That is, the theoretical solar altitude h can be obtained from Equation 1.
sinh = sinφ · sinδ + cosφ · cosδ · cosω (Formula 1)

Further, the theoretical solar azimuth angle ψ can be obtained from Equation 2.
From the relational expression of cosψ = (sinφ · sinh−sinδ) / cosφ · cosh,
sinψ = cosδ · sinω / cosh (Formula 2)

  FIG. 14 is a flowchart illustrating a processing flow for generating a tracking drive signal that has been corrected by the installation method according to the third embodiment of the present invention.

Step S30:
The drive control unit 5 calculates the theoretical solar altitude h and the theoretical solar azimuth angle ψ based on the formulas 1 and 2 previously incorporated in the memory as a program. The theoretical solar altitude h and the theoretical solar azimuth angle ψ are a reference position (flange surface as a reference surface) of a biaxial drive composed of a tilt rotation axis AXi (tilt rotation reference axis) and a swing rotation axis AXr (swivel rotation reference axis). This is a value calculated as a theoretical value assuming that the position corresponding to 4a is correctly located and there is no deviation (azimuth deviation and inclination).

  Note that a computer program for performing the following processing flow is installed in the drive control unit 5 in advance, and processing can be instructed via appropriate operation means.

Step S32:
Using the correction parameters (azimuth deviation ψ0, inclination α, inclination β (or azimuth deviation ψ0, inclination α0, inclination β0) of the reference plane) stored in the memory as the measurement result, the solar altitude deviation hd, sun An azimuth shift ψd is calculated.

  Since the actually installed support column 4 (reference plane) has a slight deviation (azimuth deviation, inclination) with respect to the ground surface (horizon), the reference position of the biaxial drive is similarly displaced, Accurate tracking corresponding to the calculated solar orbit (theoretical solar altitude h and theoretical solar azimuth angle ψ) cannot be performed, resulting in a shift in tracking drive.

  In addition, if the origin of the tilt rotation axis AXi (for example, set when it is perpendicular to the horizon) and the origin of the rotation axis of rotation AXr (for example, set when the sun azimuth is true east) are not accurately determined, Accurate tracking corresponding to the solar orbit (theoretical solar altitude h and theoretical solar azimuth angle ψ) cannot be performed, resulting in a shift in tracking drive.

  As described above, the deviation of the reference plane can be defined by the orientation deviation ψ0, the slope α (or α0) in the north-south direction, and the slope β (or β0) in the east-west direction. Further, since the reference position of the biaxial drive is aligned with the reference surface (flange surface 4a), the inclination α (or α0) in the north-south direction is the inclination of the turning axis AXr and the tilting axis AXi with respect to the north-south direction. In addition, the inclination β (or β0) in the east-west direction corresponds to the inclination of the turning rotation axis AXr and the inclination rotation axis AXi with respect to the east-west direction.

  Therefore, the deviation (tilt) of the turning axis AXr and the tilting axis AXi is corrected using the azimuth deviation ψ0, the inclination α (or α0) in the north-south direction, and the inclination β (or β0) in the east-west direction as correction parameters. A correction value necessary for correction can be obtained. That is, it is possible to calculate the solar altitude deviation hd and the solar azimuth angle deviation ψd as intermediate expressions (correction values) for correcting the solar orbit calculation formulas (Formula 1 and Formula 2).

  The solar altitude deviation hd and the solar azimuth angle deviation ψd can be calculated as functions in the form of equations 3 and 4 using the azimuth deviation ψ0, the inclination α, and the inclination β. It should be noted that the calculation can be made in the same manner when the azimuth deviation ψ0, the inclination α0, and the inclination β0 are used.

Solar altitude deviation hd = f (ψ0, α, β) (3)
Solar azimuth deviation ψd = g (ψ0, α, β) (4)
Note that the azimuth deviation ψ0, the inclination α, and the inclination β (or the azimuth deviation ψ0, the inclination α0, and the inclination β0) can be easily, accurately, and rapidly measured as described above, and therefore, the turning rotation axis AXr and the inclination rotation axis AXi. It is possible to easily calculate the solar altitude shift hd and the solar azimuth shift ψd that can correct the shift.

Step S34:
By correcting the theoretical values of the solar orbit (theoretical solar altitude h, theoretical azimuth angle ψ) with correction values (solar altitude deviation hd, solar azimuth angle deviation ψd), the driving solar altitude hr, the driving sun The optical azimuth angle ψr is calculated.

  That is, the driving sunlight altitude hr and the driving sunlight azimuth angle ψr are obtained by Expressions 5 and 6.

Driving solar light height hr = h + hr (5)
Driving sunlight azimuth angle ψr = ψ + ψd (6)
Step S36:
A tracking drive signal corrected based on the driving sunlight altitude hr and the driving sunlight azimuth angle ψr is generated and output to the tracking drive unit 3. Since the tracking drive unit 3 (two-axis rotation mechanism drive system) can be controlled by the tracking drive signal corrected in accordance with the installation state (installation deviation) of the reference surface, the influence of the installation state of the reference surface It becomes possible to track the solar orbit with high accuracy and accuracy without receiving any.
