Cutter working condition monitoring device based on voice identification technology

This utility model discloses a knife working condition monitoring device based on speech recognition technology. The device has solved the problem that the knife monitoring in current manufacture industry is not able to meet the actual demand. In addition, it is simple in structure and convenient for use, and it can use several knives, etc. The structure of the device is as follows: the device includes the collection device of the knife cutting sound signal, and this device collects various knife's cutting sound feature signals and the real-time sound signal of the inspected knife; the collection device is connected with the pre-play and amplification control device, converts the sound signal into analog/ digital, amplifies and the eliminates the noise, and sends the generated digital signal into the speech recognition device. The device inputs the feature knife cutting signal into the memory device as the comparison benchmark for the real-time signal; the real-time cutting signal of the detected knife will be matched with the comparison benchmark signal, and then the comparison result will be input into the output device.
