Description

Alarm and shut off system to prevent access

The present invention relates to an alarm and a blocking system for preventing access, and more particularly, having an independent power source using a solar cell and a secondary battery, the wildlife or illegal access of a certain area such as a road or a crop cultivation area. When an approach is detected, a virtual barrier is formed and an alarm is sent to return the approaching animal or person, and the driver who moves around the road visually indicates that the wildlife is in the wild. The present invention relates to an access detection and alarm system that can prevent safety, as well as damage in restricted areas including crop growing areas.

As the large natural predators have disappeared recently, elk, raccoon or wild boar are rapidly increasing, and the habitat is gradually fragmented and the fragmentation of the ecosystem due to the increasing roads has led to a sudden jump into the driveway during the feeding process. Traffic accidents due to road-kill that leads to death are increasing year by year.

In particular, road kill accidents occurring on highways induce a situation in which the steering wheel is steered or braked instinctively to avoid a sudden situation, which may lead to an accident such as a collision with a vehicle or a collision with a rear vehicle. There is a need for countermeasures because there is a great risk, such as the possibility of increasing the possibility, causing a major accident that threatens the life of the vehicle occupants beyond the damage of the vehicle or the death of wild animals.

In order to prevent such road kill accidents, eco-corridors may be created on the roads, or fences may be installed to prevent the entry of wild roads and guide the eco-paths. There is bound to be a limit.

In this regard, Korean Utility Model Publication No. 20-2012-0004019 (published on June 8, 2012; hereafter referred to as 'Patent Document 1') outputs high-frequency or low-frequency sounds other than audible frequencies that humans can hear beforehand. There is known a technology for preventing road kills to prevent traffic accidents by preventing wild animals, etc., from approaching a car.

According to the patent document 1, a microcomputer for generating ultrasonic waves, a control module including an amplification device for receiving and amplifying the ultrasonic waves from the microcomputer, the speaker receiving the amplified ultrasonic waves from the control module and the power to the control module It includes a power supply for supplying, and a manually operated power switch, it characterized in that the animals that can hear the ultrasonic waves to approach the vehicle by emitting ultrasonic waves to the outside of the vehicle.

On the other hand, Republic of Korea Patent Publication No. 10-2013-0045782 (published on May 06, 2013; hereinafter referred to as 'Patent Document 2')) prevents road kills that can suppress vehicle accidents for wild animals in motion by the vehicle in operation Techniques for systems are known.

According to the Patent Document 2, a detection unit for detecting the movement of the wild animal within a range adjacent to the road, when the detection unit detects the movement of the wild animal is synchronized to guide the wild animal out of the range and generates an alarm signal The display unit and the detecting unit, the alarm unit and the display unit, which are disposed apart from the detecting unit, and display a warning message for the driver driving the vehicle approaching the detecting unit to be alert when the detecting unit detects the movement of the wild animal. A control unit is electrically connected to each of the units and receives a detection signal from the detection unit to drive the alarm unit and the display unit. The control unit suppresses the entry of the wild animals approaching the road and further drives the wild animals entering the driveway. To detect wild animals adjoining or entering the driveway. And wherein to alert while driving in a car unhaengja.

On the other hand, Republic of Korea Patent Publication No. 10-2013-0085668 (published Jul. 30, 2013; hereinafter referred to as 'Patent Document 3')) to prevent road kills to protect the wildlife as well as guard the vehicle occupant safety Techniques for fence systems are known.

According to the Patent Document 3, the first and second vehicle detection sensors are installed at predetermined intervals on the road lane to detect the movement of the vehicle, and a plurality of dogs are respectively connected and installed along both edges of the road so that the animals are on the road.

As it is.

However, looking at the prior art, there is a limit in that the patent document 1 is configured to be temporarily used by the driver by manually operating the power switch instead of always operating. In other words, road kills are caused by wild animals that suddenly appear when traveling on secluded roads without street lights at night. Preventing road kill itself is very difficult to expect in reality, and although there are animals that respond to frequencies lower than sound waves, it is configured to use only ultrasonic waves, so the choice of sound sources for road kill prevention is narrow. The scope of use is also very limited. In addition, in the case of Patent Document 2, there is no problem that there is no method for physically blocking access to the wild animal, and in the case of Patent Document 3, a barrier wall for blocking access to the wild animal is separately provided.
