JPH11126280A - Small-sized trespass preventing device consisting of solar battery and supercapacitor - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain maintenace-free constitution as to battery replacement, etc., by equipping a power source part with a solar battery and a supercapacitor and generating an alarm sound with a reed switch which is turned on and off by two magnets as a door, etc., is opened or closed. SOLUTION: The solar battery 1 as a power source increases electricity accumulation with a small quantity of light together with the supercapacitor 2 as a capacitor to reach the operation level that an electronic buzzer 3 requires. When a sliding door or hinged door fitted with an external magnet 6 is closed, a magnet 5 which holds the reed switch normally ON cancels the magnetic force to turn off the reed switch 4. This state is maintained and then when a trespasser opens the door, the external magnet 6 leaves the magnet 5, so that the electronic buzzer 3 generates an alarm sound. Therefore, if there is the trespasser while the electric power is charged, the reed switch 4 is turned on, the supercapacitor is turned on to start charging, and the alarm electronic buzzer 3 continues to sound, thereby preventing the trespass.

Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention comprises a super capacitor used in combination with a solar cell as a power supply device. In the description of the drawings, reference numeral 3 in FIG.
This is an intrusion prevention device with an alarm that generates an alarm sound in response to opening and closing of a sliding door or a door by a magnet mechanism. The solar cell used as a power source can be used even with a small amount of light (about 10 lux) by using it together with a super capacitor.
As the power storage increases, the electronic buzzer reaches the required operation level C, and further increases depending on the condition based on the light amount. If there is an intruder at the time of charging, the switch is turned on and the supercapacitor immediately starts discharging and the alarm electronic buzzer continues to sound for about 2 minutes, so that intrusion can be prevented. As described above, a small intrusion prevention device with an alarm comprising a solar cell and a supercapacitor.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses a solar cell as a power source, and saves time and effort for replacing a battery by a conventional dry cell system. The present invention relates to an intrusion prevention device.

[0002]

2. Description of the Related Art In the past, there have been few cases where an alarm device is attached to a sliding door or a door and used for crime prevention in a house, and an intruder who may come at any time because of relying on a commercial power supply or a small dry battery. In contrast, the power supply had to be running at all times. Therefore, it was difficult to manage power outages and replacement of dry batteries.

[0003]

SUMMARY OF THE INVENTION The present invention is a maintenance-free device which solves a major drawback in the prior art because it does not require power management or troublesome management of replacing batteries. The present invention relates to a small intrusion prevention device having a power supply device composed of a solar cell and a supercapacitor which can be used semi-permanently.

[0004]

According to the present invention, there is provided a third circuit diagram.
In the figure, 1 is a solar cell, 2 is a super capacitor, and the capacity is about 0.1 farad. 3 is an electronic buzzer, 4 is a reed switch, 5 is a small magnet for keeping the reed switch on at all times, so that the reed switch is turned on. Reference numeral 6 denotes an external magnet attached to a sliding door or hinged door, which was turned on by 5 and 4 was turned off because the magnetic force was canceled by 6. By maintaining such a state, if there is an intruder, 6 is separated and an alarm is issued. Conventionally, the use of dry batteries in 2 required the battery to be replaced after its life had expired. However, the present invention uses a battery called a supercapacitor instead of this dry battery, that is, a small intrusion using a solar battery for charging using a capacitor. It is a prevention device. Installation environment (1
At 0 lux, the charging time is relatively long (around 2 hours), but the alarm time that works is around 2 minutes, so that there is no excessive adverse effect on the neighborhood.

[0005]

The curve A in FIG. 4 according to the present invention shows that after charging the supercapacitor, there is a charge of 3.8 VOLT even if the light is shielded, and the charge of 2.8 VOLT is maintained even after 24 hours. Alarm was given without any problems. Therefore, this numerical value greatly exceeds the operation level C of the electronic buzzer shown in FIG. 4 (about 2 VOLT). Next, B short-circuits the supercapacitor to completely discharge it, and then connects the solar cell to the window (1) near the dark room.
(0 lux), the buzzer reached the operating level in about 2 hours.

[0006]

Embodiments of the present invention will be described below. First
The figure is a perspective view, wherein 1 is a solar cell, and 6 is an external magnet. 2 is a supercapacitor, 3 is an electronic buzzer, 4 is a reed switch, 5 is a magnet for operating an alarm buzzer, 6 is a magnet attached to a sliding door or door or window, and counteracts 5 with 6 to act. When approaching, 4 becomes OFF. The description of FIGS. 3 and 4 is as described above.

[0007]

As described above, the use of a solar cell as a power supply unit and a supercapacitor as described above provides an economically complete, maintenance-free, semi-permanent and small permanent intrusion prevention device that is completely free from the risk of battery replacement. be able to.
