Abstract
A distributed networked data acquisition system having distributed networked data acquisition devices based on embedded Linux development platform having an ARM9 CPU is proposed. The system is defined as one or more distributed networked data acquisition devices together with a host. The host could dynamically display data and also coordinate and control the many distributed networked data acquisition devices. Each distributed networked data acquisition device is connected with the host by means of transmission media. The distributed networked data acquisition devices adopts the distributed data acquisition network to implement multi-point data acquisition having many distributed networked data acquisition devices working together and using several UTPs to connect with the distributed networked data acquisition devices in various distribution points. Each distributed networked data acquisition device can connect with different types of sensors, and each sensor can collect different types of continuous signals.
