An electronic fence is a perimeter defense and alarm system, consisting of detection, signal transmission, alarm linkage and other parts. It can provide human figure detection within a designated area. When someone attempts to cross the boundaries around the protected area, the detection device on the boundary can detect the intrusion and issue a warning. It can also transmit the intrusion signal to the alarm linkage part to prompt relevant personnel to handle the situation.

With the electronic fence system, there is no need to arrange personnel to stand guard at the ancient tree site. By providing real-time monitoring information, the safety of this precious ancient tree can be safeguarded at all times.

The information perception system set up for ancient trees includes soil information collection and environmental information collection. With the help of Internet of Things (iot) technology, the soil information collection system can collect data such as nitrogen and phosphorus content, pH value, and soil temperature in the soil of ancient tree roots. The environmental information collection system can collect data such as air quality, wind force, water volume, light, and ultraviolet rays around ancient trees. The collection and accumulation of these data have provided scientific data support for the protection of ancient trees.
