A Duplex Wireless Audio Communication System

摘要：

This paper mainly introduced the principle, hardware, software, functions and technical difficulties of the system. This system applied wireless communication technique, audio frequency technique and network technique. The functions was carried out by embedded system. Its core part was Micro-Controller Unit ET44M210, and it included several Sub-systems. They were J2A Audio Encoding and Decoding Sub-system, RF Wireless Communication Sub-system, OLED Manifestation Sub-system, Alarm Sub-system and FLASH Memory Sub-system. This system was used in the hospital and it can make real-time communication, medical record management, calling alarm and calling manifestation integrate together then worked perfectly with each other. This duplex wireless audio communication system contacted patient and paramedic quickly and efficiently, so it can raise the nursing efficiency, lighten the intensity of labour, improve the service level of hospital.
