Spare part defection system for distributed control system

The invention relates to a spare part detection system of a distributed control system. The system comprises a detection unit and a test platform; the detection unit includes a detection loop composedof spare part mounting mechanisms; the test platform is in communication connection with the detection unit and is configured with detection logic of spare parts to be detected; according to the detection unit, the spare parts to be detected are installed through the spare part mounting mechanisms; and the test platform controls the operation of the detection loop through the corresponding detection logic, collects the operation parameters of the spare parts to be detected, and outputs the detection results of the spare parts to be detected. According to the technical schemes of the invention, performance parameter detection can be performed before the spare parts are installed on the distributed control system, and therefore, loss caused by damage to the spare parts installed in the distributed control system ca
