There are various types of bird sounds and the sounds of natural enemies of birds, etc. stored in the signal chip. The sound of bird repelling can be selected according to actual needs to drive away the birds that steal fruit. Then the control chip determines whether to execute the bird repelling alarm program. If executed, the sound signal of the sound signal will be adjusted by the volume control circuit. Here, the sound decibel can be adjusted according to the size of the orchard area to avoid unnecessary noise to the surrounding area. noise interference. Then, the volume of the tweet is amplified by the power amplifier circuit according to the volume adjustment setting, and played through the speaker circuit. The number of the speaker circuits can be adjusted according to the actual situation of the orchard area and region, so as to achieve the complete coverage of the orchard and achieve the effect of deterrence. If the bird repelling alarm procedure is not executed, the alarm system returns to waiting. If the system is in manual mode, through the day/night control circuit and the bird-repelling alarm day button S5 and bird-repelling alarm night button S6 in the button circuit, the control chip stores the bird-repelling alarm during the day and does not alarm during the day. There are four modes of bird repelling alarm at night and no alarm at night. First, the day/night switching circuit is used to determine whether it is day or night, and then the bird repelling alarm day button S5 and the bird repelling alarm night button S6 are used to amplify the loudspeaker circuit.

[0034] like figure 1 , image 3 , Figure 4 and Figure 5 As shown, an orchard anti-theft alarm device includes a power supply circuit and a control chip. The control chip is respectively connected to an alarm access circuit and a sound signal circuit, and the alarm access circuit is connected to an intrusion detection device. The sound signal circuit is connected to the second power amplifier circuit, the second power amplifier circuit is externally connected to the speaker circuit, the control chip is respectively connected to the third-party alarm system and the day/night switching circuit, and the day/night switching circuit is provided with a Transistor Q1, the collector of the transistor Q1 is connected to the control port P0 of the control chip through the first resistor R1 and is powered by the power port VCC1 through the power supply circuit, the power port and the collector of the transistor are connected in series with a second resistor R2, so A photoresistor RG and a capacitor C1 are connected in parallel between the base of the transistor Q1 and the ground, a third resistor R3 is connected between the power port VCC1 and the base of the transistor, and the emitter of the transistor is grounded. A volume control circuit is connected between the sound signal circuit and the second power amplifier circuit, the third-party alarm system is connected by an Ethernet for system alarm, and the power circuit provides the day/night switching circuit power supply .

[0035] The control chip is respectively connected to a button circuit and a display circuit. The button circuit includes an arm/disarm button S7 and an anti-theft alarm button S8. One end of the arm/disarm button S7 and the anti-theft alarm button S8 is connected to a pull-up resistor R47 respectively. and R48, the pull-up resistor is powered by the power circuit VCC. The vacant ends of the arm/disarm button S7 and the anti-theft alarm button S8 are grounded, the display circuit includes a screen display circuit and an indicator light circuit, the screen display circuit displays the alarm position and the alarm time, and the indicator light circuit functions Device status indication, the indicator light status indication of the indicator light circuit is matched with the button function

[0036] The control chip is connected to a high-frequency switch circuit, and the high-frequency switch circuit is connected to an acousto-optic device circuit for on-site sound alarm and light strobe. The power supply circuit is provided with a backup power access circuit, and the number of the speaker circuits is 1-5.

[0037] At the beginning, the anti-theft alarm device does not work. First, determine whether the system is in manual mode or automatic mode. If it is in automatic mode, first determine whether it is day or night through the day/night switching circuit, and judge whether it is day or night according to the pre-set program. Anti-theft alarm, for example, at night, the day/night switching circuit determines whether it works at night, and then the intrusion detection device monitors whether someone enters the orchard without permission. If there is an alarm, the control chip determines whether it is a point alarm or a system alarm.

[0038] If it is a point alarm, the intrusion signal detected by the intrusion detection device is transmitted to the alarm access circuit, which is transmitted from the alarm access circuit to the high-frequency switch circuit and then connected to the external sound and light equipment circuit, and is triggered by the external sound and light equipment circuit to realize on-site alarm and The strobe light has the effect of deterrence and alarm. Then the alarm sound is issued by the alarm sound circuit, and the volume is adjusted by the volume control circuit at this time, and then the sound is amplified by the power amplifier circuit and played by the speaker circuit. If the guards find that the alarm information is reset through the button circuit point, if they do not find that the speaker circuit keeps playing the alarm. If the system alarms, the intrusion signal detected by the intrusion detection device is transmitted to the alarm access circuit, and the detected intrusion signal is transmitted to the third-party alarm system through the Ethernet to notify the duty personnel. At the same time, the alarm access circuit is transmitted to the external sound and light equipment circuit, and the on-site alarm and light strobe are triggered by the external sound and light equipment circuit, which has the effect of deterrence and alarm. Then the alarm sound is issued by the alarm sound circuit, and the volume is adjusted by the volume control circuit at this time, and then the sound is amplified by the power amplifier circuit and played by the speaker circuit. If the on-duty staff finds that the alarm information is reset through the unified system of the third-party alarm system, if not found, the speaker circuit keeps playing the alarm. If the system is in manual mode, the day/night control circuit cooperates with the anti-theft alarm button in the key circuit, and the control chip stores four modes: daytime anti-theft alarm, no alarm during the day, night anti-theft alarm, and no alarm at night. The /night switching circuit judges whether it is day or night, and then judges whether it is burglar alarm by the input of the anti-theft alarm button S8. Then, it is the same as in the automatic mode, first judge whether it is a point alarm or a system alarm, then adjust the volume by the volume control circuit input, and the first power amplifier circuit amplifies the speaker circuit, etc., which will not be described in detail here.

[0039] The power supply circuit is provided with a backup power access circuit. It ensures the normal operation of the alarm device in the state of emergency power failure.

[0040] The day/night switching circuit can automatically switch the circuit under the condition that the guard can't see the actual condition of the orchard clearly at night, and can also switch to the manual mode through the button circuit. Set the alarm device according to actual needs. In the automatic state, the day/night switching circuit can sense the intensity of the light through the photoresistor RG, so as to realize the switching of not working during the day and working at night. When there are guards in the orchard during the day, the alarm device can be prevented from running all the time. work, reduce the burden of equipment and reduce waste of resources. In the manual switching mode, for example, setting the bird repellent alarm device needs to work during the day, while the anti-theft alarm device only works at night when the guards cannot see the condition of the orchard, so as to make reasonable use of the alarm equipment to avoid wasting resources and cause equipment failure. Use burden.

[0041] The anti-theft device has a dual-purpose function of alarm and system alarm, which can timely remind the management personnel of the behavior of birds stealing food and man-made theft in the orchard. And the number of speaker circuits can be adjusted according to the actual situation of the orchard area and region to achieve a deterrent effect.
