Oil depot Internet of Things equipment state monitoring and automatic switching method

The invention discloses an oil depot Internet of Things equipment state monitoring and automatic switching method, and relates to the technical field of monitoring and early warning. The method comprises the following steps of: establishing a main and standby equipment corresponding relation model, setting a synchronous or asynchronous operation rule, establishing a time and fault risk relation model, setting an early warning threshold value and an automatic switching threshold value in the model, collecting data in real time by an equipment data module, storing the data in a database, transmitting acquired parameters to a time and fault risk relation model, and judging a state of current equipment; if the state is abnormal, finding out standby equipment corresponding to the fault equipment, starting standby equipment data information collection, and sending out alarm information; and if the state is normal, displaying detailed decision-making information, and providing an auxiliary decision plan and a tracki
