The concept of network control was extended to let digital switches communicate with databases (known as Service Control Points) and signalprocessing systems (Intelligent Peripherals).
网络控制的概念被扩展到了让数字交换机与数据库（称为服务控制点）和信号处理系统（智能外设）通信。

This paper involves ANN based intelligent condition monitoring and diagnosing of loaders, focusing on signal collecting and processing as well as characteristic parameter picking up.
Based on mechanism research of various HV motor incipient faults, an online intelligent diagnosing instrument based on digital signalprocessing (DSP) techniques is developed successfully.
