Real-time operation state monitoring method for ETC portal equipment based on Internet of Things

The invention provides a real-time operation state monitoring method for ETC portal equipment based on the Internet of Things, and the method comprises the steps: obtaining an overall impact matrix through building a matrix function of a correlation factor, and obtaining an alarm upper limit threshold matrix and an alarm lower limit threshold matrix through the overall impact matrix; obtaining anupper limit threshold alarm matrix and a lower limit threshold alarm matrix according to each real-time monitoring value matrix, the alarm upper limit threshold matrix and the alarm lower limit threshold matrix, obtaining an alarm matrix according to the upper limit threshold alarm matrix and the lower limit threshold alarm matrix, and calculating to obtain an influence weight matrix through an associated equation matrix and the alarm matrix; and finally, according to the influence weight matrix, determining core parameters influencing the running state of the portal. The core parameters influencing the running state
