Automation To Keep The Control System Design And Implementation

Keeping watch on speech signals is one kind of work which can often be seen in telecom, medical treatment, military affairs, and so on. This kind of work often faces to long time noise. Moreover, some kinds of data must be automatically recorded according to their special character. In early systems, people must be an intervenor in the whole work flow, from the signal incepting to the signal keeping watch. It's sure that this work is easy to make people feel tired and unhealthy. Fallibility is also be carried by the physical limitation of the recording devices. According to speech signals, in most computer systems, the main audio-device is an audio card. Although there are more than one audio cards in many computers, the operation systems on them always allow user using one of the audio cards as the only one in use. But in some units, people need more than one audio cards to work at the same time in one computer on the workstation desktop in order to collect multi routes of audio data. Accordingly, we must also be able to switch the audio channels. The data collected by audio card often contains noises, and this circs is more serious in my unit. In order to ensure the quality of data and improve the working conditions, we should take measures to judge and reduce the noises in the data. After being collected, the audio data must be dealt with, perhaps also be transferred in intranet. Because there are some other application systems which use the intranet to transfer data, we must consider the questions about multicast.The Author comes up with a new solution of automatic keeping watch. This solution is based on the design of hardware systems and software systems. Computers are its kernel. In this way, automatic keeping watch is implemented in a certain extent. The main results of the author's work are as follows:1. Design and implementation of audio data's collecting, transferring and dealing with. We solved the problem of judging the existence of sound from noises.2. Design and implementation of hardware drivers based on Windows.3. Design and implementation of multi audio cards'control in Windows.4. Design and implementation of mass devices'remote control.
