Data Acquisition module is the basis of the intelligent supervision and management system of embedded network devices. Due to the diversity and complexity of the acquisition object, it calls for higher requirements on compatibility and scalability in data acquisition frame. This paper creates a solution of data acquisition based on SNMP, embedded Internet technology, network management technology and multithreading. It improves compatibility and scalability and proposes a remote Web data acquisition frame with high generality, high compatibility and high portability. The data acquisition frame is designed and implemented with multi-threading technology and multi scheduling stages, which plays an important role in the intelligent supervision and management of embedded network devices.
