Description

[Detailed description of the invention] "Industrial application field" This invention relates to a bird and beast alarm device for driving away harmful birds and beasts.

``Conventional technology'' Conventionally, harmful birds such as pigeons, crows, and sparrows, as well as rats, weasels,
There are alarm devices to exclude nocturnal pests such as foxes. However, it has been difficult to automatically activate the alarm in a timely manner when pests appear.

``Problem that the invention seeks to solve'' This invention aims to create an alarm system that uses solar cells, body heat sensors, illuminance sensors, etc. to automatically drive away harmful birds and beasts in a timely manner when they appear. be.

``Means for solving the problem'' This proposal consists of a power supply circuit consisting of a solar battery installed at an angle on the outside of the machine casing, a storage battery connected to the solar battery, an alarm, a body heat sensor, and the body heat sensor. an alarm operation control circuit connected to the sensor and capable of driving the alarm based on the detection operation of the sensor; and an alarm operation control circuit connected between the power supply circuit and the control circuit and controlling the power of the power supply circuit based on the illuminance sensing operation. The bird and beast alarm is equipped with an illuminance sensor that supplies power to the control circuit and sets the control circuit to an operating state, and the sensor is formed by a daylight sensing and/or dark sensing resistor. .

"Function" Therefore, when the machine casing 1 is installed on a high-voltage line tower, a field, etc., the solar cell 2 generates electricity and charges the storage battery 5 during the day. The illuminance sensor 4 using a daylight sensing resistor supplies power from the power supply circuit to the alarm operation control circuit 8 based on daylight detection, and sets the control circuit 8 to an operating state. In this operating state, when a bird or beast approaches and the body heat sensor 10 detects its body heat, the control circuit 8 drives the alarm 3 based on the detection operation to drive away the bird or beast.

Also, at night, the electric power stored during the day is supplied to the control circuit 8 based on the sensing operation of the illuminance sensor 4 using the dark-sensitive resistor, and when the control circuit is in operation, the body heat sensor 10 detects the approach of birds and beasts. The alarm device 3 is activated based on the detection.

Either one of the daylight sensing and dark sensing resistors can be selected depending on the behavior pattern of the bird or beast to be chased away, or both can be provided.

"Example" As shown in Figures 1 to 4, a solar cell 2 is installed on the top surface of the cabinet 1 at an angle to allow rainwater to flow down, and an illuminance sensor 4 is installed on the front. A storage battery 5 connected to the solar cell 2 is installed inside the cabinet 1, and a power supply circuit 6 is formed by the solar cell 2 and the storage battery 5. An alarm 3 is installed on the front of the cabinet 1 using a speaker 3', and an amplifier 3" connected to the speaker 3' and a voice synthesis IC 9 connected to the amplifier 3" are installed inside the cabinet 1 to form the alarm circuit 7. In addition to the voice synthesis IC 9, a cassette tape audio playback device may be used. This sound may be the terrified cries and warning cries of birds and animals, or the cries of natural enemies (birds of prey, etc.). The power supply circuit 6
The illuminance sensor 4 is connected to the alarm circuit 7, and an alarm operation control circuit 8 is provided between the sensor 4 and the alarm circuit 7. When the illuminance sensor 4 is formed of a daylight sensing resistor, the sensor 4 operates in daylight to supply power from the power supply circuit 6 to the control circuit 8, setting the control circuit 8 in an operating state and functioning as a power switch.

The far-infrared difference temperature sensing body heat sensor 10 (body heat sensor) is connected to the control circuit 8, and detects the body temperature of an approaching bird or beast during the daytime when the control circuit 8 is in operation, and the control circuit 8 detects the body temperature. Send a signal. The control circuit 8 drives the alarm circuit 7 based on the detection operation of the sensor 10, thereby emitting the sounds of birds and animals from the speaker 3'.

Further, a dark-sensing resistor is used as the illuminance sensor 4, and this resistor is installed in the front of the machine casing 1, and the power stored in the power supply circuit 6 during the daytime is supplied to the control circuit 8 by the dark-sensing operation of the resistor. The control circuit 8 is set to an operating state from evening to night, and nocturnal animals (foxes, mice, etc.) can be chased away by the alarm circuit 7 based on the detection operation of the body heat sensor 10.

Further, the illuminance sensing sensor 4 may be configured to use both a daylight sensing resistor and a dark sensing resistor so that the alarm can be activated both during the day and at night.

In the figure, reference numeral 13 indicates a mounting bracket for the machine casing 1.

Moreover, what is shown in FIG. 5 is another embodiment of the present invention, in which the control circuit 8 is provided with a 24-hour timer 8'', and the above-mentioned alarm operation by the body heat sensor 10 or the alarm by the above-mentioned timer 8'' It is designed to be able to perform actions. In the device shown in FIG. 5, the alarm operation by the timer 8'' can be performed by setting the time when a harmful bird such as a crow appears or disappears in the timer 8'' in advance, and when the time comes, the above control is activated. The circuit 8 operates the alarm circuit 7 to issue an alarm. With this configuration, the alarm can be automatically activated only during the daytime or nighttime hours when birds and beasts appear.

``Effects'' As described above, the present invention uses a solar cell as the power source, so there is no need for a separate power source, and the alarm operation can be performed even at night due to the power storage function of the storage battery.

In addition, it is equipped with an illuminance sensor and a body heat sensor, and can automatically detect the approach of birds and animals during the daytime or night, or at any time of the day, and issue an alarm. It is possible to carry out a targeted and effective alarm operation.
