[0002] Voiceprint recognition, also known as speaker identification, is a biometric technology that identifies or verifies an individual's identity by analyzing their voice characteristics. It can also identify the identity, working status or failure mode of a device, machine or mechanical system by analyzing the sound or vibration signals generated when the device, machine or mechanical system is in operation. It can be used to classify, monitor or diagnose equipment.

[0003] Ultrasonic flowmeter is a non-invasive flowmeter that uses the characteristics of ultrasonic wave propagation in fluid to measure flow velocity or flow rate.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1 -Attached Figure 7 , further details of this application are given.

[0039] A voiceprint recognition fault warning device, referring to Figure 1 and Figure 4 , including a fluid pipeline 1 for fluid flow, a group of measuring pipelines 2 for measuring fluid are flange-connected between two groups of fluid pipelines 1, a group of ultrasonic flowmeters 3 are fixedly connected to the top middle end of the measuring pipeline 2, which can measure the fluid in the measuring pipeline 2, and also includes an early warning mechanism 4 installed at the outer end of the measuring pipeline 2.

[0040] Specifically, the fluid flows in the two groups of fluid pipes 1 , and is measured by the ultrasonic flowmeter 3 when passing through the measuring pipe 2 .

[0041] Reference Figure 1-Figure 3 The early warning mechanism 4 includes a connecting tube 41, a quick-release mechanism 42, a collecting mechanism 43 and a fixing mechanism 44. The connecting tube 41 is installed at the middle end outside the measuring pipe 2. The front and rear ends of the connecting tube 41 are both connected to the quick-release mechanism 42. The collecting mechanism 43 is provided at the middle end of the top of the connecting tube 41, and the rear end of the collecting mechanism 43 is connected to the fixing mechanism 44.

[0042] The components of the two sets of quick-release mechanisms 42 are the same. The quick-release mechanisms 42 include side panels 421, limit frames 422, flanges 423, through slots 424 and limit rods 425. The connecting tube 41 is divided into an upper and a lower part, and the front and rear ends of the upper and lower parts are fixedly connected to a set of side panels 421. The right end of the top side panel 421 is hinged to a set of limit frames 422. The right end of the bottom side panel 421 is provided with a notch corresponding to the limit frame 422, which is conducive to the rotation of the limit frame 422. The upper and lower ends of the limit frame 422 are fixedly connected to at least two sets of flanges 423. When the limit frame 422 rotates to the upper and lower ends of the two sets of side panels 421, the flanges 423 can squeeze the two sets of side panels 421 to improve the tightness and stability of their fit. The middle ends of the upper and lower side panels 421 are provided with through slots 424 that are connected to each other, and a set of limit rods 425 are slidably connected in the two sets of through slots 424.

[0043] Among them, the length of the limiting rod 425 is longer than the length of the through slot 424, and the ends of the two groups of limiting rods 425 that are away from each other are both opened into an arc shape. When the upper and lower groups of side plates 421 are fitted together, the two groups of limiting rods 425 squeeze each other, so that the two groups of limiting rods 425 extend toward the upper and lower ends respectively. When the limiting frame 422 rotates to the upper and lower ends of the two groups of side plates 421, it can be stuck in the outer end arc groove, which is conducive to limiting the limiting frame 422.

[0044] Among them, the bottom surface of the upper side panel 421 is provided with a limit slot 4211, and the top of the limit slot 4211 is fixedly connected to a magnetic plate, and the top surface of the lower side panel 421 is fixedly connected to a corresponding limit protrusion 4212. The limit protrusion 4212 can be absorbed by the magnetic plate and inserted into the limit slot 4211, which can improve the convenience when connecting the two sets of side panels 421.

[0045] Specifically, the two sets of limit frames 422 can be rotated to make the front and rear sets of side plates 421 fit tightly together, thereby achieving connection stability between the connecting tube 41 and the measuring pipe 2.

The ultrasonic flowmeter 3 can extend into the movable tube 433 through the transition tube 431. A group of annular groove parts 432 are fixedly connected to the top surface of the transition tube 431. The top surface of the annular groove part 432 is provided with an annular groove. The bottom end of the movable tube 433 can be inserted into the annular groove, which is convenient for limiting and fixing the movable tube 433. At least two groups of microphone arrays 434 are installed at the inner end of the movable tube 433, which can improve the collection efficiency of the working noise of the ultrasonic flowmeter 3. A group of identification modules 435 is installed at the bottom of the right end microphone array 434. The identification module 435 can analyze and identify whether there are cavitations or abrasive particles in the fluid through the difference in the working noise of the ultrasonic flowmeter 3, and can send signals to the external terminal for early warning.

[0047] Among them, an observation window 4331 is opened at the middle end of the top of the movable cylinder 433, which is convenient for observing the working condition of the ultrasonic flowmeter 3. Sound-absorbing cotton 4332 is adhered to the inside of the movable cylinder 433. The sound-absorbing cotton 4332 can reduce noise such as echo, make the sound clearer, and improve the sound collection effect.

[0048] Specifically, the movable cylinder 433 is placed on the outside of the ultrasonic flow meter 3, and the working noise is collected through the microphone array 434. The recognition module 435 recognizes and warns the staff.

The arc plate 443 can drive the slide plate 444 and the movable cylinder 433 to rotate backward, exposing the ultrasonic flowmeter 3 in the movable cylinder 433, which is convenient for adjusting the ultrasonic flowmeter 3;

[0050] The left and right sides of the fixed arm 442 are fixedly connected to a set of expansion seats 445. The middle ends of the expansion seats 445 are rotatably connected to a set of connecting rods 446. The upper ends of the connecting rods 446 extend to the upper ends of the expansion seats 445 and are fixedly connected to a set of locking arms 447. The bottom front ends of the two sets of locking arms 447 are each provided with two slots corresponding to the left and right ends of the top surface of the movable cylinder 433. The two sets of locking arms 447 can be clamped on the left and right ends of the top surface of the movable cylinder 433 to facilitate limiting the position of the movable cylinder 433.

[0051] The lower ends of the connecting rods 446 extend to the lower ends of the extension seats 445 and are fixedly connected with a group of locking parts 448. The left and right ends of the rear annular groove part 432 are both provided with a group of card slots corresponding to the locking parts 448, which are conducive to the limited locking of the locking parts 448.

[0052] Specifically, when the connecting rod 446 rotates outward, it can drive the locking arm 447 and the locking piece 448 to rotate outward, releasing the limit on the movable cylinder 433, so that the movable cylinder 433 can slide upward along the slide plate 444, exposing the ultrasonic flow meter 3 in the movable cylinder 433, and drive the slide plate 444 and the movable cylinder 433 to rotate backward through the arc plate 443, so as to facilitate the adjustment of the ultrasonic flow meter 3 and improve flexibility during use.
