Description

The present invention uses a radio wave of a telemetry transmitter used in a survey of the area of activity, etc., in addition to the purpose of eliminating harm to humans and damage to crops by wild animals, and also protects wild animals. The present invention relates to a device that can be used and a method for utilizing an alarm that is issued by the device. The target of utilization is target wild animals such as Japanese monkeys, deer, bears, wild boars and so on.

There has been a conventional receiver that focuses on the telemetry transmitter and receives this transmitted radio wave to know the position of the other party. Skilled people concentrate on reception, approach wild animals with their feet, try to know the trends, and residents who do not have specialized knowledge can use it for the purpose of countermeasures against birds and beasts in their daily activities Not like that.

Conventional measures against damage to birds and beasts have been focused on extermination, but the damage has been increasing year by year. On the other hand, there are many birds and animals that are protected from the viewpoint of nature conservation and species conservation. I was not there. Some receivers tried to know the approach by using a telemetry transmitter and using the transmitted radio wave, but there was some skill in using the receiver, that is, operation There is a problem that it requires technology and does not always notice the reception of the telemetry signal unless the reception state is taken care of. When receiving a radio wave from a telemetry transmitter, the influence of noise and the like was large, and the reception sensitivity (sensing distance) was not enough to predict the approach in the daily living space. And, in most cases, the response to knowing the approach ends with the contact with the administrative window, and the response on the spot is not taken, that is, the immediate approach to the approach of wild animals is possible. It wasn't.

A device will be installed that uses the radio waves transmitted by the telemetry transmitter to receive, alert, and record actions to understand the behavior of wild animals.

When installing, an independent power supply using solar panels can be used to enable operation even without a commercial power supply.

When wild animals approach, alerts are issued so that timely and effective evacuation can be performed.

Receives signals from telemetry transmitters attached to wild animals even if they are 500m to 1km away (line-of-sight distance), and informs the residents of the approach with sound or light from a rotating light, etc.

The self-control that anyone who lives there can carry out the segregation (living) of the living sphere of humans and wild animals by carrying out self-control, that is, the eviction action by prediction.

It is possible to eliminate damage from birds and beasts by using the device and method described in. Because it does not require killing, wildlife can be protected at the same time, achieving both wildlife protection and wildlife protection, which were previously considered to be conflicting.

In the installation and operation of the present invention, the Japanese monkeys which are most difficult to deal with due to damage from birds and beasts were targeted. The six sites where the test was set up, except for one, had almost no damage in the surrounding area, and the remaining one, except for the fields on the mountainside, had almost no damage. It was confirmed that the effect of the evacuation action performed by predicting in this way was enormous. In addition, some people came to change the course that the group moved at an early point because people went out, and there was no area approaching the area itself.

Regional power is the key to results. The cooperation between local residents, that is, the systematic evacuation action is the most effective way to increase the effect, and the installation of the present invention also creates a region where the cooperation and communication in the region has improved. It is not desirable to set up near the field and leave the daily living space of the residents from the viewpoint of quick response (prevention by prediction). Concentration, response tends to be delayed, and preventive effect due to prediction is difficult. Since the present invention provides stable sensitivity capable of sensing the approach even from a distant place, it is possible to know the approach of wild animals even if it is installed in a person's daily living space. Therefore, since it is possible to provide information on “approach” to many people who live at the same time, it is possible to quickly and systematically drive out and prevent by prediction.

The present invention includes an outdoor antenna, a reception unit, a noise countermeasure unit, a signal control unit, an alarm transmission / display unit, an operation recording unit, and a power supply unit. When commercial power is not available, or when it is installed as a portable type, it can be handled by combining independent power sources with solar panels. In order to achieve stable reception, improvements are made in sensitivity, noise countermeasures, and signal processing. An alarm can be issued with a received signal of 0 db or more, and the alarm can be maintained up to -6 db. In order to reduce malfunction due to noise other than radio waves of the purpose (telemetry transmitter), the receiver has a built-in limiter (noise reduction circuit), and the antenna and power supply incorporate an arrester to take countermeasures, making it non-directional By adopting an outdoor antenna (gain 4.5dbi), it is possible to stably receive a radio wave transmitted from a telemetry transmitter attached to an animal at a distance of 500m to 1km and to generate an alarm. When the telemetry transmitter signal is received, it is notified by sound, and the light of the rotating lamp is used to inform the residents of the approaching wild animals. The alarm sound is only received at the beginning of reception, and the revolving light always lights up during reception. Also, by checking and investigating the receivable range in advance, it is possible to know which range the wild animal has approached. The type of alarm can be arbitrarily changed depending on the conditions of the installation location, including the setting of detection sensitivity (distance), the type and volume of alarm sound, the type of alarm light emission and the operating time. With this warning, residents go out with fireworks for driving away from their fields, and when wild animals are seen there, fireworks are fired away (active measures). Local residents can know where wild animals have appeared with the fireworks that have been struck, making it possible to systematically drive them away through support. Even if you can't see the wildlife, you can see that there is a person on the animal side. You will not get close to it, and there will be no damage to birds and beasts (predictive preventive measures).
Incorporating a recording function of reception operation into this device, and recording and storing the reception frequency, operation (on / off) date and time of the telemetry transmitter, it is possible to keep a history of when and what wild animals appeared in the detection range. This makes it possible to conduct an accurate survey of the wild animal's range of action, and to more reliably implement measures against damage to birds and beasts. The connection between the operation recording unit and the external computer is general RS232c, and the history data stored in the text format can be taken out to the outside.
