    • A custom-shaped wireless fence system is provided that contains one or more dogs in a user-defined containment area without the need for a physical fence or underground wire. The system, which is easy to set up and use, includes at least three base units and at least one collar and, preferably, a remote controller. A virtual fence is defined around the containment area, as well as around optional exclusion zones within the containment area, during system set up through communication between the base units and a trackable device as the user walks around the desired border. Visualization software enables the user to verify that the location of the fence is as desired and that the system is operating properly using a computing device having a display screen. In use, the system employs improved filtering of consecutive distance measurement values taken between the base units and the collar to discount errant measurement values in terms of their contribution to the current calculation of the dog's location. These filtering techniques, in combination with improved signal strength and antenna diversity in the communication between the base units and the collar, improve the accuracy and consistency with which the dog's location within a containment area is tracked so that unwanted corrections are not administered to the dog.
    • 提供了一种定制的无线围栏系统,其中包含一个或多个狗在用户定义的容纳区域,而不需要物理围栏或地下线。 易于设置和使用的系统包括至少三个基本单元和至少一个轴环,并且优选地包括遥控器。 在系统设置期间,通过围绕所需边界行进的基本单元和可跟踪设备之间的通信,在围拢区域周围以及围绕安全壳区域内的可选的禁区区域围绕着虚拟围栏。 可视化软件使得用户能够使用具有显示屏幕的计算设备来验证栅栏的位置是否符合要求,并且系统正在正确地操作。 在使用中,系统采用对基本单元和领之间采用的连续距离测量值的改进过滤,以便根据其对当前狗的位置计算的贡献来折扣错误的测量值。 这些滤波技术结合改进的信号强度和在基座单元和套环之间的通信中的天线分集提高了跟踪包围区域内狗的位置的准确性和一致性,从而不对狗施加不需要的校正 。
