The invention relates to a distributed code detection method. According to the method, the detection is performed by means of a detection system. The distributed code detection method comprises the following steps: initializing a parameter; introducing function reference; integrating data flows; resolving a constraint set; and backtracking a result. The detection system comprises a control end and distributed terminals. The control end is used for managing each distributed terminal E, providing integrated preprocessing of codes of the detection system and allocating the preprocessing to the distributed terminals E for performing co-processing; the distributed terminals are responsible for detecting distributed codes. The detection method disclosed by the invention is used for resolving the data flows, the resolved data flows are co-processed by using different distributed terminals, and thus the problem of a detection load of processing of original single equipment is reduced, and the capacity of processing codes is increased.
