The invention discloses a gravity detection based novel elevator operation prewarning device. The gravity detection based novel elevator operation prewarning device comprises a power supply module, a 51 single-chip microcomputer microcontroller, a human body detector module, a timing module, an alarm module, a floor position detection module and a system terminal, wherein the human body detector module, the timing module, the alarm module, the floor position detection module and the system terminal are connected with the 51 single-chip microcomputer microcontroller. The floor position detection module is implemented by the aid of a laser emitter, a laser receiver and a bottom reflection device, and the human body detector module consists of a gravity sensor. When a passenger in an elevator is in a coma and a vibration range of data measured by the human body detector module is kept within a set threshold for three minutes, the alarm module sends alarms and accident data to a terminal. By the aid of the gravity detection based novel elevator operation prewarning device, alarms can be automatically sent to the system terminal in occurrence of suspected accidents, and accident information including accident time, running direction, elevator position and the like can be provided for the terminal. Furthermore, the gravity detection based novel elevator operation prewarning device has the advantages of simple principles, low cost and promising application prospect.
