Application of embedded system in information acquisition

Information chain consists of information acquisition, information processing, information transmission and information application. Compared with the other three technologies, information acquisition has dropped far behind and is becoming a bottleneck for the rapid development of the time. Embedded system has been successfully applied in industrial automation, communication system, wireless communication, Internet, consumer electronic and other fields that contact toughly with information processing, information transmission and information application. It is the outcome of development of the information chain´s back-end link, if applied into information acquisition, there should be sound effects. The paper does some try to apply embedded system into information acquisition. This can contribute to the development of information acquisition.
