基于集成神经网络对刚性路面脱空声的识别与分类能力，用简单的敲击法获取了刚性路面的声响应信号，通过对声信号的频域特征提取，应用集成神经网络对刚性路面脱空状况进行识别。

Based on the ability of integrated neural network in classification and identifying , an integrated neural network was applied in identifying rigid pavement cavity through acoustic feature extraction in the frequency domain obtained by acoustic responses on knocking the rigid pavement .

IBP以硬接线的方式引入外部信号，通过指示灯的亮/灭或蜂鸣器的声响表示外部信号的变化。

External signals are put into IBP through hard wiring and their changes are identified through the indicator light or sound of the buzzer .

过载、超温或轴卡滞情况发生会停止电极的工作并且会由显示指示器和声响警告器给出信号。

Overload , over-temperature , or shaft jam conditions stop the motor and are signaled by a display indicator and audible alarm .
