[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.
