Navigation aid lamp isolation transformer open-circuit state monitoring device and control method

A navigation aid lamp isolation transformer open-circuit state monitoring device comprises a principal computer system and transformer state monitoring units. The principal computer system is an industrial control computer, and is arranged in a navigation aid lamp workstation. The transformer state monitoring units are installed in a transformer barrel together with an isolation transformer (the secondary side is composed of a main winding and an auxiliary winding), is used for collecting and transmitting the information of the isolation transformer, and communicate with the principal computer system wirelessly. Through the navigation aid lamp isolation transformer open-circuit state monitoring device and a control method provided by the invention, whether the main winding of the secondary side of the isolation transformer is in an open circuit can be detected effectively, whether there is current in a navigation aid lamp loop can be detected, whether the isolation transformer or the navigation aid lamp fails can be judged and the judgment result can be reported to the principal computer system in real time, so that the problem that the navigation aid lamp loop cannot be handled in a timely manner due to failure of the windings of the isolation transformer is avoided.
