A high speed data acquisition system is composed of general-used main control platform and smart sensor network with bulk data. Aiming at status of diversification of the smart sensor nodes

difficult to manage

likely to affect security of overall system in the event of a failure problem

propose a method for identification recognition and fault processing

by construction management units binding with smart sensor nodes

and the units contact with each other by a group of independent management bus

without affecting real-time performance of intrinsic data transfer bus

the method can solve the problem of identification and trouble shooting of mass data intelligent sensor nodes. By a CAN bus-based designed example

prove the feasibility of the proposed method

and the method with simple structure has reliable performance

can greatly improve the extensibility and stability of the data acquisition system.
