The invention discloses an elevator real-time position monitoring system and method. The elevator real-time position monitoring system comprises an elevator control mainboard, an absolute value position sensor, a magnetic railing ruler and a host rotary encoder, and the magnetic railing ruler is vertically installed in an elevator shaft in a penetrating mode; the absolute position sensor is installed on an elevator car and used for reading position information of the magnetic railing ruler. The control main board is in communication connection with the absolute position sensor to obtain car position information; the host rotary encoder is electrically connected with the control main board and provides speed and car position information for the control main board; the control system obtains the position information of the absolute position sensor in real time, calculates the position information of the host encoder, compares and corrects the position information of the absolute position sensor and the host encoder, and ensures that when the absolute position information sensor breaks down or the position is lost, the position information of the rotary encoder on the host side can be adopted for stable parking. And the relation between the current speed and the remaining stopping distance is monitored in real time, so that the running safety of the elevator is effectively improved.
