Referring to fig. 1 to 3, the present invention provides a state monitoring system for a high temperature superconducting pinning magnetic levitation vehicle-mounted dewar, comprising: the Dewar type electronic monitoring device comprises a Dewar 10, a Dewar state monitoring module 30 installed on the Dewar 10, a control module 20 electrically connected with the Dewar state monitoring module 30 and an alarm module 40 electrically connected with the control module 20;
