When each automatic simulation test is performed, the identification system is abnormal, and the operating system issues a ladder stopping base station instruction; and sends maintenance instructions and information to the elevator. Or displaying that the elevator stops running to be repaired. In addition, each time the elevator automatically simulates a test, it is recommended that maintenance personnel be present to arrange self-tests and daily maintenance.
