Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a door unlocking system using a solar cell, which uses a solar cell and a secondary battery as power sources and controls unlocking of the door using an optical signal.

[Conventional technology]

As the social structure has changed and nuclear families have become more popular, residential complexes have become increasingly high-rise and concentrated. In this situation, demands on the living environment have diversified, and electronics such as home automation have been actively adopted.

[Problem that the invention seeks to solve]

However, most conventional door locking systems, even cylinder locks, use old-fashioned key unlocking methods, although there are electronic locking systems. These conventional methods involve various problems because the key must be inserted into the keyhole for operation. For example, if there is insufficient lighting in front of the door and it is difficult to identify the keyhole position, it may be difficult to unlock the door.

Similar problems also occur for users with poor eyesight.

The present invention solves the above-mentioned problems, and aims to provide a door unlocking system using a solar cell that is simple and highly reliable.

[Means for solving problems]

To this end, the door unlocking system using solar cells of the present invention includes a portable transmitter that has a solar cell placed in front and uses the solar cell as a power source to transmit a specific light signal, and an illumination system that illuminates the solar cell and its surroundings. A door hardware with a lamp placed on the front is provided, and the door hardware includes:
The device is characterized by having a built-in control means that detects the illuminance from the output of the solar cell and controls the lighting of the illumination lamp, and also detects the specific light signal and controls the unlocking of the door. The present invention is characterized in that a solar cell is also arranged on the door frame side of the door hardware, so that light can be introduced into the solar cell from the door frame side to ensure power supply.

[Effect]

In the door unlocking system using solar cells of the present invention, when the front illuminance decreases, the illumination lamp turns on and a portable transmitter emits a signal.
Kasu+8 Thunder Oil Surrounding Edict l Yuna's A When using a portable transmitter to unlock a door, you can check the exact direction of the call, and use the portable transmitter in that direction. You can easily unlock the door by simply sending a signal. Furthermore, the system can be installed without any electrical wiring by simply attaching a door hardware equipped with a solar battery and a secondary battery charged by the solar battery.

In Fig. 1, 1 is a portable transmitter, 2 is a door handle, 3 is a hardware door attachment, 4.7 and 9 are solar cells,
5 is a switch, 6 is a light emitting element, and 8 is an EL. The portable transmitter 1 corresponds to a conventionally carried key, and has a built-in signal generation circuit that generates a specific signal and a secondary battery, charges the secondary battery with a solar battery 4, and uses it as a power source. By operating the switch 5, the light emitting element 6 sends out an optical signal of a specific frequency or pulse train code.

The door handle 2 includes a solar cell 7 that serves as a receiving section for control signals from the transmitter 1 and a detecting section for sunset and sunrise, and an EL (illumination lamp) 8 for nighttime display.
It is placed around the . The switch 21 is a touch switch used when manually releasing the lock without using the portable transmitter 1. For door installation, the hardware 3 incorporates a secondary battery, a circuit for identifying and processing a lock release signal, a circuit for determining sunset and sunrise and controlling the lighting of the EL, and a solar battery 9 on the door frame side. This is what was placed. The light emitting element 19 sends out a lock release signal (solenoid on signal) which will be described later, and the light emitting element 25 requires charging which will be described later. A light supply section and a light receiving element are provided facing each other. Then, for example, a condensing lens is provided outdoors, and the light collected here is guided to a light supply section through an optical fiber to irradiate the solar cell 9.
By charging the secondary battery with the output of the door, the required power can always be secured without the need for electrical wiring between the hardware 3 and the door frame. Further, in combination with this, the illuminance may be detected when there is insufficient sunlight, a lamp is turned on, and the light is guided to the light supply section so that the solar cell 9 is irradiated with light. Examples of solar cells include amorphous silicon solar cells and single-crystal silicon solar cells, secondary batteries include high-performance rechargeable carbon lithium batteries, and EL include ultra-thin surface emitters. each used.

With the above configuration, the portable transmitter 1 uses the solar cell to receive light and generate electricity, and uses the output to charge the secondary battery, so there is no need to worry about changing batteries or running out of batteries, and you can press the switch 5 at any time. It can be operated to send an unlock signal. On the other hand, on the door side, since light is always supplied from the door frame side, the secondary battery can be charged using the power generated by the solar cell 90. When the illuminance in front of the door decreases, the EL8 is turned on to illuminate the area around the solar cell 7, so the solar cell 7, which is the signal receiving surface, can be recognized even at night or when the front of the door is dark. The unlock signal can be reliably transmitted from the transmitter 1 toward the solar cell 7.
