A wide range of electronic dog training collars (e-collars) is available in the UK, but information enabling purchasers to compare the important characteristics of these collars is not available. In this research, the electrical characteristics of 13 e-collar models were examined, and an approach to ranking the strength of the electrical stimuli was developed. To achieve this, the electrical impedance of dogs' necks were measured so that e-collars could be tested under realistic conditions. This impedance was found to be about 10 kΩ for wet dogs and 640 kΩ for dry dogs. Two replicates of eight e-collar models and single copies of a further five models were then examined. The stimuli generated by these collars comprised sequences of short high-voltage pulses. There were large differences between e-collar models in the energy, peak voltage, number of pulses and duration of the pulses, but little variation between the replicates. The peak voltage varied with the impedance, from 6000V at an impedance of 500 kΩ to 100V at 5 kΩ. The highest voltages were generated for a few millionths of a second. Stimulus energy levels at the maximum strength setting with a 50 kΩ load ranged from 3.3 mJ to 287 mJ. A stimulus strength ranking indicator was then developed to enable the strengths of e-collars with diverse electrical characteristics to be ranked. This ranking shows a wide range in the stimulus strengths of collars, and that the relationships between 'momentary' and 'continuous' stimuli for various models differ significantly.
英国市场上有各种各样的电子训犬项圈（e collar），但没有信息可以让购买者比较这些项圈的重要特性。在这项研究中，我们检查了 13 种电子项圈模型的电气特性，并开发了一种对电刺激强度进行排序的方法。为了实现这一目标，我们测量了狗颈部的阻抗，以便在实际条件下测试 e 项圈。结果发现，湿狗的阻抗约为 10 kΩ，干狗的阻抗约为 640 kΩ。然后，我们检查了两个 8 个 e 项圈模型的副本和另外 5 个模型的单个副本。这些项圈产生的刺激由短高压脉冲序列组成。不同 e 项圈模型之间在能量、峰值电压、脉冲数量和脉冲持续时间方面存在很大差异，但在副本之间差异较小。峰值电压随阻抗而变化，从 500 kΩ 时的 6000V 到 5 kΩ 时的 100V。最高电压仅持续几微秒。在 50 kΩ 负载下，最大强度设置时的刺激能量水平范围为 3.3 mJ 至 287 mJ。然后，我们开发了一个刺激强度排名指标，以便对具有不同电气特性的 e 项圈的强度进行排名。该排名显示了项圈刺激强度的广泛范围，并且不同模型之间“瞬间”和“连续”刺激之间的关系有显著差异。
