The invention relates to a distributed network data collector based on embedded Linux developing platform, which uses the ARM9CPU with ARM920T inner core as CPU and adopts a plurality of data collectors and the host control machine to form the system. The host control machine achieves the dynamic display of a plurality of data collecting and the coordinate control of a plurality of collectors; the data collector is connected with the host control machine and other devices by the transmitting media; it adopts the distributed data collecting network, the multi-card group net operating, and uses the concentrator to make the net; it adopts a plurality of twisted-pair line to connect the data collector of each distributed point and each data collector to connect a plurality of sensor; the sensor collects different type of continuous signal; the device achieves the multi-point data collecting by the control of the host control machine.
