Description

Technical Field

[0001] This utility model provides an electronic fence monitoring and alarm system based on UWB communication, belonging to the field of electronic fence monitoring and alarm technology. Background Technology

[0002] With the rapid development of IoT technology, positioning and area monitoring technology has gradually become an important research direction. In industrial safety, asset monitoring, and unmanned operation scenarios, electronic fences, as a security boundary control method that can detect and respond in real time, have received widespread attention and application. However, the electronic fence technology currently used usually relies on positioning methods such as GPS, RFID, or Bluetooth, which have certain limitations in terms of positioning accuracy, anti-interference ability, and adaptability to complex environments.

[0003] Ultra-wideband (UWB) technology is a high-bandwidth, low-power wireless communication technology with extremely high time resolution and strong anti-interference capabilities. It can achieve high-precision positioning in complex environments, help electronic fences achieve real-time detection and response functions, and enable real-time, high-precision monitoring within a certain range.

[0004] However, existing UWB electronic fence systems only provide simple positioning functions and lack the ability to optimize energy consumption and adapt to dynamic scenarios. For example, the UWB base stations set up in the target area do not have corresponding alarm mechanisms and can only transmit the currently detected tag location information to the monitoring terminal of the management personnel, resulting in poor real-time monitoring. When a tag crosses the electronic fence, there is only post-event recording information feedback, which cannot provide timely alarms and lacks monitoring feedback with the upper-level system. In addition, the tag structure is simple and has limited functions. When UWB communication data is transmitted and received at high frequency, the tag power consumption will be high, and the installed batteries cannot support long-term use, making the entire electronic fence system unable to meet the application requirements in complex environments.
