Network problems. Because of too many login personnel, the network system of Xi 'an elevator safety administrator examination system in Shaanxi Province collapses and the network is disconnected, which will cause the examination system to be abnormal. As long as the system is shut down and the network is reconnected, the network will return to normal, and the elevator safety administrator examination system in Xi 'an, Shaanxi will also return to normal. Elevator safety administrators are mainly responsible for familiarizing themselves with and implementing national policies and regulations on elevators, formulating relevant management measures according to the actual situation of their own units, constantly improving elevator management, and checking and correcting irregularities in elevator use.
