The invention relates to the field of elevator operation detection. The problem of detection errors caused by the air pressure change of an air pressure type elevator running state monitoring device in the prior art is solved. The elevator running state monitoring method comprises the steps that an air pressure sensor collects air pressure information at the fixed frequency; and when an elevator car stops, the air pressure Py collected by the air pressure sensor is compared with the air pressure value corresponding to each floor, the air pressure Pm closest to the air pressure Py is found, the elevator car is located at the floor Lm corresponding to the air pressure Pm at present, and the air pressure corresponding to each floor is updated according to the following formula. The elevator running state monitoring device comprises an air pressure sensor, a signal processing circuit and a power supply circuit, the air pressure sensor is in signal connection with the signal processing circuit, and the power supply circuit supplies power to the air pressure sensor and the signal processing circuit. The elevator video monitoring device comprises the elevator running state monitoring device and a video signal receiving and transmitting module.
