Detailed description of the invention
Make specifically to introduce to this utility model below in conjunction with the drawings and specific embodiments.
Seeing Fig. 1, the fault pre-alarming device being applicable to point machine of the present utility model includes: audio collecting device, signal amplification circuit 3, digitized processing and sound pick-up outfit and terminal handler.Wherein, audio signal when point machine is worked by audio collection device is acquired and transmits to signal amplification circuit 3, being amplified by signal through signal amplification circuit 3 and transmit to digitized processing and sound pick-up outfit, signal amplification circuit 3 is connected by video line 7 with digitized and sound pick-up outfit；Then, digitized processing and sound pick-up outfit carry out analog-to-digital conversion process to audio signal and store, finally, terminal handler extracts prestore in digitized processing and sound pick-up outfit or the digital signal of real-time reception, utilize band filter to be filtered operation, promote calculate condition code through signal framing, FFT, normalization cepstrum again, finally carry out fault pre-alarming judgement.
When carrying out fault pre-alarming and judging, detailed process is: the abnormal work audio group condition code prestored in the audio feature code calculated and terminal handler compared, when the audio feature code calculated falls into abnormal work audio group, the equipment of being considered as there occurs fault, now triggers warning or interlocked operation carries out fault pre-alarming.Therefore, before this prior-warning device formally comes into operation, need gather substantial amounts of abnormal work group audio frequency and carry out being calculated condition code, be stored in terminal handler and device work process carries out condition code compare to facilitate.
As shown in Figure 2, audio collecting device of the present utility model includes a pick up 1 and for installing the pick up fixed support 2 of pick up 1, during use, pick up 1 presses close to the outer wall of goat, that is, prior-warning device of the present utility model is completely isolated with the electrical system of goat, does not affects, does not interfere the normal operation of goat, thus early warning reliable results is without dispute.
Specifically, connecting for convenience, pick up fixed support 2 includes mounting seat and be connected seat vertically disposed with mounting seat, and pick up 1 is fixed on connection seat top；Being formed with the link slot for installing bolt in mounting seat, installing bolt in link slot can be fixed on pick up fixed support 2 on ground or arbitrary fixed mesa.
