The invention provides a method and device for monitoring the opening and closing state of switch equipment, which are applied to a sequential control host in a transformer substation system. The method comprises the steps of when an operation signal is received, determining the switch equipment corresponding to a switch number in the operation signal, and obtaining a remote signaling signal generated by the switch equipment through displacement; judging the opening and closing state of the switch equipment based on the remote signaling signal to obtain a first judgment result; sending the operation information to an intelligent auxiliary system so as to enable the intelligent auxiliary system to call a preset video camera to acquire an opening and closing state picture of the switch equipment, and judging the opening and closing state of the switch equipment based on the opening and closing state picture to obtain a second judgment result; and determining the opening and closing stateof the switch equipment based on the first judgment result and the second judgment result. By applying the method, the opening and closing state of the switch equipment can be determined more accurately, workers do not need to arrive at the site to determine the opening and closing state of the switch equipment, and the time for determining the opening and closing state of the switch equipment isshortened.
