Wherein the microphone module 26 has one or more microphones, by arranging the microphones of the microphone module 26 at key locations in the industrial system where voiceprint signals need to be detected, voiceprint signals at key locations in the industrial system can be collected. The microphone module 26 is associated with the main controller module 20 to transmit the signals collected by the microphone module 26 to the main controller module 20, wherein the microphone module 26 is connected with the main controller module 20 through a data line, the microphone module receives and corresponds to a sound source with a frequency of 20Hz-20kHz, and the microphone module 26 is correspondingly smooth in a frequency band, wherein the microphone module is not limited to one microphone and can be one microphone or a plurality of microphones; the power module 21 is used for supplying power to the main controller module 20, the main controller module 20 is associated with the server through the wireless mobile communication module 25, and data interaction is performed between the main controller module 20 and the server through the wireless mobile communication module 25. The storage module 24 is used for collecting and storing sound source data transmitted to the main controller module 20 by the microphone module 26, so as to prevent data loss caused by signal transmission failure, and the storage module 24 is connected with the main controller module 24 through a data line; the wireless communication module 23 is used for reading/setting the address of the wireless mobile communication module, reading/modifying the address of the server and diagnosing the running state of the whole voiceprint acquisition and test device.

Furthermore, in the detection of voiceprint signals of key parts in an industrial system, the invention can collect real-time audio information of the key parts in the industrial system in real time through the microphone module 26, and preprocess the collected audio information, wherein the preprocessing comprises the following steps: pre-filtering, voice endpoint detection, FFT analysis processing and the like, and uploading the data to a server. The main controller module 20 is responsive to the audio signal received from the audio bus built in the microphone module 26 to preprocess the audio signal.

Therefore, after the collected signals are preprocessed, voiceprint signals of key parts in the industrial system can be detected and collected in real time, and whether faults exist in the key parts of the industrial system can be known remotely through the server.

In some embodiments, the collected data and the preprocessing result are actively pushed to a server through a wireless mobile communication network. Uploading data and receiving commands according to a certain specific mode, the voiceprint acquisition testing device adopts the following data naming mode:

when the voiceprint acquisition testing device adopts a passive mode, after the voiceprint acquisition testing device is powered on, the local port is monitored, and active connection of the server side is waited. When the communication is not established, the server should actively search the voiceprint acquisition testing device at regular time, and if the connection is established successfully, a transmission starting command is sent. And after receiving the start transmission data, the voiceprint acquisition testing device acquires the data at regular time according to the set acquisition time interval and actively uploads the data. In the process of not transmitting data in the middle, the server side needs to send heartbeat messages at regular time to maintain a communication link. If the server side does not receive the data or the heartbeat message after a certain time, the connection is disconnected, and the connection is retried. If the voiceprint acquisition testing device does not receive the message of the server side after overtime, the previous connection is just disconnected, the local port is intercepted again, and the connection is waited.
