Bird repellent and anti-theft alarm device in orchards

Abstract

The invention discloses a bird repellent and anti-theft alarm device in orchards. The bird repellent and anti-theft alarm device in the orchards comprises a bird repellent alarm device and an anti-theft alarm device. The two devices are connected to a daylight / night switching circuit and a volume control circuit through control chips respectively. The daylight / night switching circuit reduces the using burden of equipment and reduces resource waste. The volume control circuit can conduct volume adjustment according to the size of the area of the orchards and avoid unnecessary noise interference to the surroundings. The anti-theft alarm device can also achieve point alarm and system alarm, and a manager can be reminded of bird stealing and eating and human theft behaviors in the orchards.

Description

technical field [0001] The invention relates to an electronic alarm device, in particular to an alarm device used in orchards to drive away birds and prevent people from entering the orchard and stealing.

Problems solved by technology

Currently on the market, the orchard bird repellent and anti-theft alarm devices work 24 hours a day. For orchard bird repellent, if the birds rest at night and do not look for food, it will cause waste of resources; for the anti-theft alarm device, If there are guards patrolling normally during the day, it will cause waste of resources; long-term operation increases the burden of equipment use, and most of the current anti-theft devices are point alarm systems, that is, intrusion detection devices are installed in the orchard. Drive the loudspeaker equipment, and the alarm sound will be generated by the loudspeaker in the place where the problem occurs, but in a large orchard, the sound from the loudspeaker located farther away may not be heard by the guards
