The equipments working in the Internet of Things environment are relatively complex,and the cost of the artifi-cial detection are high,so the detection error of fault equipments is big. Therefore,a detection system for fault equipments based on Internet of Things was designed and implemented. The system acquires the real-time parameters of the fault equip-ments through its acquisition module,utilizes GPRS communication module of the controller SIM900B to transmit the informa-tion among various modules,adopts the detection and diagnosis module of core chip S7-200 PLC to analyze and process the in-formation of the fault equipments,and then judges the fault reasons and location to realize the real-time management and diagno-sis of the fault equipments. In the process of software design,the technological process of the fault equipment detection system based on Internet of Things was analyzed in detail. The program code of receiving and processing the fault equipment data by the wireless sensor node is provided. The experimental results show that the proposed system has the high feasibility and practi-cability.
