The present invention relates to an elevation tracking device of a solar panel and a message display device using the same. More specifically, in a mounting structure of a solar panel having a mechanism for tracking the sun in a horizontal direction, the solar panel is tracked by tracking the altitude position of the sun. It relates to an elevation tracking device of a solar panel that can automatically change the inclination angle of the panel. In addition, the present invention relates to a message display device that displays a message, in particular an advertisement or a promotional message by using the solar panel.

Background Art Conventionally, solar panels using solar energy as power storage and power generation devices using natural energy have been widely popular, and their use is increasing. The most efficient use of these solar panels is to set them at least perpendicular to the sun. By the way, some sun tracking mechanisms have been proposed to horizontally rotate the sun by tracking the position of the sun from sunrise to sunset, but it is common to set the elevation of the solar panel in advance, and artificially fix the altitude. It was.

Conventionally, it is possible to consider displaying messages, especially advertisements and advertisements of a store, outdoors by using a facility equipped with a solar panel or a wind power generator on a land fixed to the ground. However, it is difficult to secure sufficient electric power for a conventional solar panel or the like and a luminaire for advertising and propagation in a wind power generator. This is because, when the solar panel is fixed, power generation, charging, or electric power with sufficient efficiency could not be obtained in relation to the solar visual angle.

It is provided. That is, when rotating synchronously with the standby gear 21 of the rotational arm 32, the rotation can be controlled by operating the limit switch 31. FIG.

In addition, in the present embodiment, the limit switch 31 is disposed at three positions of the rotational origin (0 degree) position and the end point (157.5 degree) position of the rotating mechanism and the position plus 15 degrees to the origin for emergency stop, so that it does not operate normally. It is possible to prevent and correct malfunctions in case of failure.

Here, a description will be given of the control system of the rotating device of the solar panel of the present embodiment, the power of the solar panel 18 and the wind power of the windmill are both input to the controller, converted by the inverter, and attached to the prop 1. It is used to activate the LED message display or to emit LEDs for pilot or other purposes. In addition, the power input to the controller is configured to charge and secure a part of the sealed lead acid battery, and the controller, the inverter, the lead acid battery, and the like are accommodated in the control box installed near the strut 1 and grounded.

In addition, the control of the rotation angle of the solar panel 18 will be described. The encoder 25 is rotated by the motor 23, and is generally referred to the origin sensor on the right side and the end point on the left side with respect to the attachment arm 2. Sensors are installed, and the standard operating range is 6 am to 6 pm, which is the sunshine time, but can be calibrated in winter and summer respectively.

When the above-mentioned origin sensor and end sensor are input and activated, the signal is input to the signal generator of the origin sensor and the angle pulse generator of the angle detection sensor (high frequency sensor 26) to generate pulses of a predetermined voltage. The rotation of the encoder 25 is sequentially detected by the angle detection sensor and input to the angle pulse generator, and the pulse signal is measured by the angle detection counter. The output from the lead acid battery is converted by the inverter and applied to the motor 23.

The initial setting of the solar panel 18 calculates the solar position at that time by latitude and longitude, sets it according to the time, and finishes setting the time and position by using the time setting switch and the correction switch. Since the time monitoring timer is excited as a crystal oscillator, the sum (end) of the hourly pulse signal and the hourly forward timer is theoretically obtained to be a flip-flop setting signal. The angle detection counter does not generate a pulse signal until the angle is 15 degrees, which is 360 degrees divided by 24 hours, thereby driving the motor 23 as a forward rotation signal.

By this forward rotation signal, the motor 23 rotates 15 degrees (corresponding to one hour) and stops. At this time, since no power is used except for the time monitoring timer, energy is saved. When the 1 hour elapsed signal is input from the time monitoring timer, the forward timer is set as the set signal by the sum (end) of the time signal obtained by adding 1 hour to the immediately preceding time, and is rotated again by 15 degrees.

By repeating the above-described operation sequentially, the solar panel 18 rotates to the position at 6 pm, that is, the end sensor position. The end point sensor is input to the front end circuit of the flip-flop in preparation for the reverse rotation from the end point signal generator, and when the set signal from the forward timer is generated, the inversion starts, restoring and stopping to the initial origin sensor. At this point, it is idle until the next sunrise.

Here, when the pivot arm 32 (the position of the solar panel 18) cannot capture a signal at the origin (0 degree: 6 am position), the pivot arm 32 can pass through the origin position. For the backup, the limit switch 31 is also disposed at the angular position at which the original position is added to 15 degrees, and corrected to return to the normal position, thereby preventing malfunction.

In addition, when an external force is applied to the solar panel 18 during the normal operation, a time delay may occur between the absolute time and the clock time inside the apparatus when moving to the origin. Therefore, when it moves further and a signal does not generate | occur | produce at the end position of 6 pm, it returns to the origin at 7 pm of absolute time, and confirms the origin signal and stops. After that, the absolute time priority processing that keeps the stop until 6 am in the standby state, that is, corrects the time difference, and performs normal operation in accordance with the absolute time.

This control is also coped with when the solar panel 18 moves toward the end point. In this case, the advance occurs at 1 hour of the internal clock, but the end signal is checked and the operation is returned to the origin, and the end point signal is checked and stopped. . Therefore, it stops until 6 pm absolute time, and corrects the time difference to start again.

In addition, when the operation of the solar panel 18 stops between the origin and the end point, the solar cell 18 immediately returns to the origin at 7:00 pm in the absolute time, and the standby state is maintained. If the solar panel 18 fails to capture the end signal and passes the end point, the limit switch 31 at 7:30 pm (157.5 degrees) is inputted to return to the origin and return to the absolute time. After 7:00 pm, wait until 6 am the next day and start normal rotation at 7:00 am.
