Smart Escort is a safety guard designed for nuclear power plants, large wind turbines, and similar facilities, in order to prevent major accidents. The system is based on technologies such as IoT, big data analysis and artificial intelligence, and it facilitates the real-time acquisition of data on tens of thousands of devices. If abnormal parameters are found, then an early warning is given and Smart Escort generates control signals that prevent device failure. An internal black box stores all data for five years.
