DESCRIPTION OF THE PREFERRED EMBODIMENTS A light irradiation leveling system according to an embodiment of the present invention will be described below with reference to the accompanying drawings. In each figure, the same components are given the same reference numerals, and redundant explanations will be omitted. FIG. 1 shows a perspective view of a light irradiance leveling system according to a first embodiment, and FIG. 2 shows a longitudinal cross-sectional view of FIG. 1. In this embodiment, the light irradiation is based on sunlight, but it may be based on artificial light. The light irradiation leveling system includes a stage 101 on which an object T to be irradiated with light is placed. The object T may be a potted plant, the surface of the platform 101 made of soil and planted with plants, or an insect in an insect cage. The mounting table 101 has a disk shape. The lower part of the platform 101 serves as a lid for a cylindrical case 102 with a bottom, and a shaft 103 extends from the center of the platform 101. This shaft 103 is connected to a motor 104 provided at the bottom of the case 102. It is the axis of rotation. The motor 104 is a moving means that moves (rotates in this case) the stage 101 on which the object to be irradiated with light is placed so that the irradiation state of the light irradiation changes. The motor 104 is, for example, a stepping motor, and can be controlled to stop rotating every 90 degrees.

Light irradiation level sensors 105-1 to 105-4 are provided on the surface of the stage 101 to detect the light irradiation level per unit time at a plurality of positions. In the present embodiment, the plurality of positions are the positions of a region obtained by dividing an annular portion of a predetermined width from the circumference of the platform 101 toward the center into four regions when viewed from the surface. The light irradiation level sensors 105-1 to 105-4 are provided at positions close to the periphery of the circle on the line segment that divides the circle of the stage 101 into four. Illuminance sensors can be used as the light irradiation level sensors 105-1 to 105-4, and the unit of the obtained measurement value is lux (lx).

A control section 200 made up of a computer is provided in the hollow part of the case 102. FIG. 3 shows the configuration of a control system centered on the control section 200. The control unit 200 is mainly configured with a CPU 210 and a main memory 220 that is connected to the CPU 210 and stores programs and data for the CPU 210 to operate as the system. The CPU 210 sets the state of the motor 104 at the start of the system as an initial state, obtains position information of the light irradiation level sensors 105-1 to 105-4 from the motor 104, and stores it in the main memory 220. Regarding the position information, for example, the position information of the light irradiation level sensor 105-1 in the initial state is set to 0, and the position information of the light irradiation level sensor 105-2 is set to a position rotated 90 degrees clockwise from 0 (0+R90). Further, the position information of the light irradiation level sensor 105-3 is set to a position 90 degrees counterclockwise from 0 (0+L90). The position information of the light irradiation level sensor 105-4 is set to a position 180 degrees clockwise from 0 (0+R180).

The CPU 210 implements the light irradiation amount detection means 211 and the movement control means 212 by the programs in the main memory 220. The light irradiation amount detection means 211 detects the amount of light irradiation for a predetermined time at the plurality of positions based on the light irradiation levels detected by the light irradiation level sensors 105-1 to 105-4. The movement control means 212 controls the motor 104, which is the moving means, based on the light irradiation amount at the plurality of positions detected by the light irradiation amount detection means 211, so that the light irradiation amount at the plurality of positions is equal. This is to move the above-mentioned table 101.

A RAM 240, an I/O interface 250, and an I/O interface 260 are connected to the CPU 210 via a bus 230. The RAM 240 is a memory used to temporarily store data created by the CPU 210 during operation. Light irradiation level sensors 105-1 to 105-4 are connected to the I/O interface 250, and the CPU 210 can take in light irradiation level data from the I/O interface 250. It is assumed that the I/O interface 250 and the light irradiation level sensors 105-1 to 105-4 are connected by a wireless communication path, and the communication path will not be disconnected due to rotation of the mounting table 101. The motor 104 is connected to the I/O interface 260. The CPU 210 controls the rotation of the motor 104 via the I/O interface 260, and can rotate the platform 101 by 90 degrees or 180 degrees and then stop it.

In the light irradiance leveling system according to the embodiment having the above configuration, the CPU 210 operates based on the flowchart in FIG. 4 . Before the operation according to this flowchart, position information of the light irradiation level sensors 105-1 to 105-4 is obtained from the motor 104 and stored in the main memory 220. The operation of the flowchart starts, the light irradiation level is detected by the light irradiation level sensors 105-1 to 105-4, and the light irradiation level detected by the light irradiation level sensors 105-1 to 105-4 is calculated for each position. In addition, the amount of light irradiation is detected over time at the positions of the light irradiation level sensors 105-1 to 105-4 (S11). Specifically, the light irradiation level (looks) is obtained by sampling, for example, every minute, and this is added to obtain the light irradiation amount.

In the next step S12, the passage of a predetermined time is detected by a timer (S12), and if NO, return to step S11 to continue the process; if YES, the difference in light irradiation amount between each position is calculated (S13). , it is detected whether at least one of the light irradiation amount differences exceeds a preset threshold (S14). If NO, the process returns to step S11 and continues; if YES, the stage 101 is moved so that the position with the minimum amount of light irradiation moves to the position with the maximum amount of irradiation (S15), and the process continues in step S12. A timer that measures a predetermined time is reset (S16), and the process returns to step S11 to continue the process.

In step S15, the positions of the light irradiation level sensors 105-1 to 105-4 have the maximum irradiation amount, and the positions of the light irradiation level sensors 105-1 to 105-4 have the minimum irradiation amount. is determined, and the motor 104 is rotated so that the minimum position moves to the maximum position.

With the above embodiment, it is possible to automatically equalize the amount of light irradiation, so there is no need for manual judgment, and there is no need to move the object receiving light irradiation, such as rotating it. Management is possible. In addition, when the object receiving light irradiation is a plant, it can reduce the loss of weight balance due to imbalance in growth, reduce the risk of tipping over in the case of potted plants, and evenly maintain the design at the time of purchase. It is possible to cultivate. In addition, when the light source is a mode, it is possible to solve the problem that the impression seen from indoors is deteriorated due to flowers blooming with stems extending toward the window. It is also expected to have the effect of suppressing diseases caused by lack of sunlight. Furthermore, it can also be used in cases where there is too much sunlight.

In the above embodiment, the number of light irradiation level sensors is provided as many as the number of light irradiation measurement positions, but the system may be configured using a smaller number of light irradiation level sensors than the number of light irradiation measurement positions. . For example, as shown in FIG. 5, a stud 141 is provided that extends upward from the upper edge 109 of the case 102 on the outside of the platform 101, and the annular rail 142 is supported by the stud 141. A moving body 143 that moves on the rail 142 is arranged on the rail 142, and a light irradiation level sensor 105X is provided on this moving body 143. The moving body 143 sends the distance traveled from the position of the light irradiation level sensor 105X in the initial state of the above embodiment as a position coordinate to the CPU 210, and each of the four points corresponding to the light irradiation level sensors 105-1 to 105-4 is sent to the CPU 210. To be able to determine the amount of light irradiation at a position. For example, the moving body 143 may be configured to stop for one second at positions corresponding to the above four points on the rail 142 to measure the light irradiation level, and then move on the rail 142 for a predetermined period of time to continue measuring. can. Other configurations are the same as those in the above embodiment.

Furthermore, in the first embodiment, the light irradiation source is sunlight and the stage 101 is rotated, but the light irradiation source may be an artificial light irradiation source. In this case, the light irradiation source may be moved so that the irradiation state of the light irradiation on the object changes. When moving the light irradiation source, a mechanism is provided to move the light irradiation source to a position on the ceiling above the four points of the light irradiation level sensors 105-1 to 105-4, and a mechanism is provided to move the light irradiation source to a position on the ceiling above the four points of the light irradiation level sensors 105-1 to 105-4. The movement shall be controlled by

Next, a second embodiment will be described. In this embodiment, as shown in FIG. 6, a stage 301 is provided on which an object to be irradiated with light is placed. The platform 301 is made up of a plurality of plate-shaped block bodies 302-1, 302-2, and 302-3 connected together. is moved using wheels. The wheels are operated by a drive source 350 such as a motor or an engine, and the drive source 350 and the wheels constitute a means of transportation. The drive source 350 is provided in the block body 302-2, and as the block body 302-2 moves, the block bodies 302-1, 302-2, and 302-3 move in succession.

Light irradiation level sensors 303-1, 303-2, 303-3 are provided on the surfaces of the blocks 302-1, 302-2, 302-3. The objects are placed on the front surfaces of the blocks 302-1, 302-2, 302-3, avoiding the light receiving surfaces of the light irradiation level sensors 303-1, 303-2, 303-3. In this way, the light irradiation level sensors 303-1, 303-2, and 303-3 are connected to the block body 302-1, which is each part when the writing table 301 is stopped, and the writing table 301 is composed of a plurality of parts. , 302-2, and 302-3, the light irradiation level per unit time at a plurality of positions is detected. That is, the light irradiation level sensor 303-1 detects the light irradiation level per unit time at the position of the block body 302-1, and the light irradiation level sensor 303-2 detects the light irradiation level per unit time at the position of the block body 302-2. The light irradiation level sensor 303-3 detects the light irradiation level per unit time at the position of the block body 302-3. Here, since there are three plurality of parts, there are also three light irradiation level sensors, but the number of blocks and light irradiation level sensors may be two or four or more. Illuminance sensors can be used as the light irradiation level sensors 303-1 to 303-3, and the unit of the obtained measurement value is lux (lx).

A control unit 200A constituted by a computer is provided inside one of the blocks 302-1, 302-2, and 302-3 (here, 302-2). FIG. 7 shows the configuration of a control system centered on the control section 200A. The control unit 200A is mainly configured with a CPU 210A and a main memory 220A that is connected to the CPU 210A and stores programs and data for the CPU 210A to operate as this system. The CPU 210A sets the state of the wheels of the block body 302-2 at the start of the system as an initial state, and stores the position information of the block bodies 302-1 to 302-3 as the position information of the plurality of positions on the platform 301 to the main memory 220A. Remember it. For example, the position information is such that the position information of the block body 302-2 in the initial state is 0, and the position information of the block body 302-1 is moved forward from 0 by a predetermined distance K1 (the length of the block body 302-1). The position is (0+K1). Further, the position information of the block body 302-3 is set to a position (0-K2) that is a predetermined distance K2 (the length of the block body 302-1) backward from 0.

The CPU 210A implements the light irradiation amount detection means 211A and the movement control means 212A by the programs in the main memory 220A. The light irradiation amount detection means 211A detects the amount of light irradiation for a predetermined time at the plurality of positions based on the light irradiation levels detected by the light irradiation level sensors 303-1 to 303-3. The movement control means 212A controls the driving source 350, which is the moving means, so that the light irradiation amount at the plurality of positions is equal based on the light irradiation amount at the plurality of positions detected by the light irradiation amount detection means 211A. This is to move the block body 302-2.

A RAM 240A, an I/O interface 250A, and an I/O interface 260A are connected to the CPU 210A via a bus 230A. The RAM 240A is a memory used to temporarily store data created by the CPU 210A during operation. Light irradiation level sensors 303-1 to 303-3 are connected to the I/O interface 250A, and the CPU 210A can take in light irradiation level data from the I/O interface 250A. A drive source 350 is connected to the I/O interface 260A. The CPU 210A controls the drive source 350 via the I/O interface 260A, obtains the moving distance based on the number of rotations of the wheels, and moves the block bodies 302-1 to 302-3 forward by a distance K1 or backward by a distance K2. It can be moved.

In the light irradiance leveling system according to the embodiment having the above configuration, the CPU 210A operates based on the flowchart in FIG. Before the operation according to this flowchart, the positional information of the blocks 302-1 to 302-3 is stored in the main memory 220A as positional information of a plurality of positions on the platform 301. The operation of the flowchart starts, the light irradiation level is detected by the light irradiation level sensors 303-1 to 303-3, and the light irradiation level is detected at multiple positions based on the light irradiation level detected by the light irradiation level sensors 303-1 to 303-3. The amount of light irradiation is detected over time at the position of a certain block body 302-1 to 302-3 (S21). Specifically, the light irradiation level (looks) is obtained by sampling, for example, every minute, and this is added to obtain the light irradiation amount.

In step S22, the passage of a predetermined time is detected by a timer (S22), and if NO, the process returns to step S21 to continue the process; if YES, the difference in the amount of light irradiation at each position is calculated (S23), and the It is detected whether the dose difference exceeds a preset threshold (S24). If NO, the process returns to step S21 and continues; if YES, the driving source 350 is controlled so that the position with the minimum amount of light irradiation moves to the position with the maximum amount of irradiation, and the block body 302-1 302-3 is moved (S25), the timer that measures the predetermined time in step S22 is reset (S26), and the process returns to step S21 to continue the process.

In step S25, the CPU 210A determines the position where the light irradiation level sensor 303-1 to 303-3 has the maximum irradiation amount and the light irradiation level sensor 303-1 to 303-3 where the irradiation amount has the minimum amount. The driving source 350 is controlled to execute the movement while obtaining the moving distance by the rotation speed of the wheels via the I/O interface 260A so that the minimum position moves to the maximum position. The second embodiment can also provide the same effects as the first embodiment.

In this second embodiment as well, the system may be configured using a smaller number of light irradiation level sensors than the number of light irradiation measurement positions. Although not shown, for example, the following configuration can be adopted. Rails are provided to connect the same positions as the light irradiation level sensors 303-1 to 303-3 of the block bodies 302-1 to 302-3. A moving body that moves on the rail is arranged on the rail, and one light irradiation level sensor is provided on the moving body. The moving object sends the traveling distance from the position of the block body 302-2 in the initial state in the second embodiment as a starting point to the CPU 210A as a position coordinate, and corresponds to the three points of the light irradiation level sensors 303-1 to 303-3. The amount of light irradiation at each position can be determined. For example, the movable body may be configured to stop at the three points on the rail for, for example, one second to measure the light irradiation level, and then move back and forth on the rail for a certain period of time to continue measuring. The other configurations are the same as those in the second embodiment.

Further, in the second embodiment, the light source is sunlight and the blocks 302-1 to 302-3 are moved, but the light source may be artificial light. In this case, the light irradiation source may be moved so that the irradiation state of the light irradiation on the object changes. When moving the light irradiation source, a mechanism is provided to move the light irradiation source to a position such as the ceiling above the three points of the light irradiation level sensors 303-1 to 303-3, and the amount of light irradiation at each position is adjusted. Movement can be controlled accordingly.
