Description
Technical Field
The invention relates to the technical field of electronic fences, in particular to an inclination induction alarm sensor.
Background
An electronic fence is a boundary protection system realized by electronic technology, and can be used for a plurality of application scenes, such as home security, zoo animal monitoring, site security, regional boundaries and the like. An electronic fence is generally composed of the following main structures: the system comprises a sensor, a controller, an alarm device and a power supply system. A sensor is one of the core components of a fence system, which is generally mounted on a post or a fixed support of a fence, and detects whether a person or object touches the fence by sensing vibration or impact on the fence, and common sensors for the electronic fence include a piezoelectric sensor, an acceleration sensor, an optical fiber sensor, or the like. The controller is a device for receiving and processing the sensor signals, and when the sensor detects vibration on the fence, the sensor transmits the signals to the controller, and the controller is responsible for judging whether to trigger an alarm or not and controlling the alarm mode and response. The alarm device can be an audible alarm, a flash lamp, a mobile phone short message notice and the like, and when the controller judges that the fence is touched, the controller can trigger the alarm device to give an alarm so as to draw attention or dispel potential intruders. The vibration electronic fence needs a power supply system to provide energy so as to support the normal operation of the sensor, the controller and the alarm device, and the power supply system can adopt a battery, a solar panel or a mains supply power supply mode and the like.
Problems with current electronic fences include: false positives and false negatives. The sensor is very sensitive to external vibrations or shocks and may therefore be affected by external disturbances, such as wind blows, vehicle passes, etc., resulting in false alarms. On the other hand, if the sensor is improperly set or damaged, a true intrusion event may not be accurately detected, resulting in a false negative. Sensitivity adjustment: in order to balance the problem of false positives and false negatives, the sensitivity of the shock sensor needs to be adjusted appropriately. If the sensitivity is set too high, false positives may increase; if set too low, a false negative may result. External interference: external environmental factors such as strong wind, earthquake and the like can also influence the vibration electronic fence, so that the problem of false alarm or missing alarm is caused. These interfering signals may be similar to the intrusion signals, increasing the difficulty of identifying the fencing system. False perception: the vibration electronic fence can generate signals when some external vibration such as animals, plants or other objects collide with the fence, and can be mistaken for an intrusion behavior, so that false perception is caused.
