Abstract

The invention relates to an emergency information media switching device of a lift car and a switching method thereof to realize the seamless switching of the emergency information and normal information. The switching device is connected with an FM (Frequency Modulation) radio module, a USB interface circuit and a relay driving circuit, wherein a contact of the relay driving circuit is connected with a control button and an audio output port of a player. The switching method comprises the following steps of: sending the frequency value of the internally stored emergency information to the FM radio module to detect whether the emergency information corresponding to the frequency value exists or not by the FM radio module; acquiring a detection result and back fed by the FM radio module and a playing state; and after the detection result with the emergency information is acquired, operating and controlling the relay driving circuit to switch the audio output content of the player from the USB interface circuit to the FM radio module and switch the audio output content back to the USB interface circuit after the emergency information is completely played.

Description

technical field [0001] The invention relates to an elevator car emergency information switching device and a switching method thereof. Background technique [0002] With the rapid development of the national economy and the continuous growth of the urban population, as a main equipment for climbing stairs, the elevator car has become an important space in people's modern urban life, but because people are in a closed and monotonous space when taking the elevator , for a long time, there will be time vacancy, psychological blankness and emotional irritability. In order to improve the elevator riding environment, elevator multimedia has emerged as the times require. To enjoy the beauty and the joy of the soul. However, the existing elevator multimedia is mostly used to play commercial information such as advertisements or music stored by itself, and cannot obtain external emergency information and play the emergency information in time. Contents of the invention [0003] T...
