The utility model provides a switch state multimode intelligent identification and confirmation platform system through the improvement, the system comprises a main control board 1 which can realize audio monitoring service, image monitoring service, closing detection service and data service, the system also comprises a microphone A2 arranged in a switch machine and a microphone B3 arranged at the switch position for sound monitoring after the improvement,
the system also comprises three groups of switching value sensors 4, 5 and 9;
the system also comprises binocular cameras 6 which are arranged on symmetrical high points at two ends of the turnout;
the system also comprises a pressure sensor 7 and a data acquisition board 8;
the output ends of the microphone A2 and the microphone B3 are connected with the data acquisition board 8, the data acquisition board 8 is connected with the main control board 1, and the output of the binocular camera 6 is connected with the main control board 1.
In the switch state multi-mode intelligent identification and confirmation platform system,
the main control board 1 is a main control platform realized by an embedded board card based on linux, and is responsible for fusing data from an acquisition end, performing logic operation and then providing turnout state information so as to finish the consistency judgment of a route and a turnout;
the data acquisition board 8 is connected with the sensors and is responsible for collecting and integrating information acquired by the sensors and driving the sensors; meanwhile, the acquisition end is in data communication with the main control platform, the sensor layer directly collects relevant information of turnout states, the information is called by the main control end, and the acquisition end is driven;
the main control platform completes the core functions of turnout state monitoring and access turnout consistency judgment on the system level through audio monitoring service, image monitoring service, closing detection service and data service; the specific implementation is as follows;
(1) audio monitoring: the audio monitoring service uses one microphone disposed in the switch machine and one microphone disposed at the switch point to carry out sound monitoring, and is used for monitoring the internal action sound of the switch machine and the sound of external switch points; in a normal state, when a large abnormal sound is received, the sound is recorded and compared with an audio library in the current turnout state and the abnormal state, and finally the abnormal state is recorded in a log and a warning signal is output. When the two groups of switching value sensors detect that the train passes through, audio information is not analyzed temporarily so as to avoid interference, and abnormal sound detection is started after the train completely passes through the turnout; when a switching command of a route driving turnout or a manual operation turnout command is sent out, a switching action sequence monitoring function of an audio sensor is triggered, regular audio during turnout switching is prepared to be received, the turnout switching is completed and then compared with a sample library, and whether turnout switching and locking are successfully executed or not is judged;
