The invention discloses an automatic support system for reusable carriers. The system establishes an automatic support system for reusable carriers through the use of distributed design of informational network, solves the problem of low efficiency caused by the traditional manual transmission of support message and demands, enhances the supportability of reusable carriers. The multi-signal flow model is used to construct the fault observation matrix which in turn is used to achieve the fast acquisition of the status information of the reusable carriers and identify the representational state data of the fault. The use of hierarchical coding format for designing the technical status code solves the problem of the complexity and low use rate of the status data information of the reusable carrier products, materializes the fast data tracking of thousands of standalone equipment products in the reusable carrier. The use of unique singular technical status code can correlate the technical status to the equipment, and clarify the procedure for updating the technical status code of the reusable carrier and make sure the technical status is consistent.
