[0017] Figure 3 Schematic diagram of a device health monitoring system for a gas desilting device according to an embodiment of the present application. Figure 4 As shown, the gas dredging device includes: a main L ; Along the main L Deployed branch pipe E 1 ~ Ex ; and multiple nozzles deployed along the branch pipe P 1 ~ P n .

[0018] In addition, reference Figure 3 As shown, the equipment health monitoring system includes: multiple vibration sensors C 1 ~ C m And with each vibration sensor C 1 ~ C m The connected processor. Further references Figure 4 As shown, the vibration sensor C 1 ~ C m The processor is arranged on the branch pipe. The processor is configured to perform the following operations: S502: When the gas desilting device is in working state, receiving corresponding first vibration signals from a plurality of vibration sensors; S504: Determine first frequency spectrum information corresponding to the first vibration signal; and S506: Determine the faulty nozzle according to the first frequency spectrum information.

[0019] Specifically, during the operation of the gas desilting device, the main L When high pressure gas is input, multiple vibration sensors C 1 ~ C m Measure the vibration at the corresponding position in real time and generate the monitoring vibration signal s 1 ~ s m (i.e., the first vibration signal) is sent to the processor, such as Figure 3 As shown. Thus, the processor receives the monitoring vibration signal s 1 ~ s m (S502).

[0020] Specifically, the gas desilting device includes a central main pipe L ,director L Branch pipes distributed on both sides and nozzles arranged on the branch pipes E 1 ~ Ex . When working, high-pressure gas is input from the main pipe to make each nozzle outlet spray gas to disperse the sludge. During its working process, there are two physical mechanisms that will cause vibration at the nozzle outlet: 1. The impact of the air flow on the nozzle. When the gas flows from the branch pipe to the nozzle, the direction of gas movement will change dramatically, and friction and collision between gas and pipe wall and gas and gas will occur. According to the distance between the nozzle and the main pipe, the flow rate of the air flow and the friction and collision generated by it decrease with the increase of distance, so each nozzle will produce vibrations of different frequencies and amplitudes. 2. When the gas is ejected from the nozzle outlet, its movement speed and pressure suddenly decrease, resulting in a sudden increase in volume, and even cavitation, which causes vibration at the outlet. When the gas dredging device is working normally, the total air pressure generated by the device is constant; and due to the high-speed ejection of gas, the sludge outside the outlet is quickly emptied and a stable jet field is formed, thereby generating stable vibration. Therefore, each nozzle has an inherent vibration frequency and amplitude according to its spatial position.

[0021] The processor can then determine, for example, by Fourier transforming the individual monitoring vibration signals s 1 ~ s m Monitoring spectrum information (i.e., the first spectrum information). Among them, monitoring spectrum information It is a vibration sensor C 1 Monitoring vibration signal s 1 Corresponding spectrum information; and so on, monitoring spectrum information It is a vibration sensor C m Monitoring vibration signal s m Corresponding spectrum information (S504).

[0022] Among them, monitoring spectrum information The details are as follows: ; ; ; … .

[0023] in It is i Vibration Sensors C i The sensed j Nozzle P j The central vibration frequency of the spectrum, is its corresponding amplitude. i =1~ m , j =1~ n . Specifically, Figure 5 Shows the i Vibration Sensors C i Collected monitoring vibration signals s i Monitoring spectrum information Schematic diagram of .

[0024] refer to Figure 5 As shown, monitoring vibration signal s i Monitoring spectrum information Including each nozzle P 1 ~ P n The central vibration frequency corresponding to the spectrum and the corresponding amplitude .

[0025] As mentioned above, each nozzle has an inherent vibration frequency and amplitude according to its spatial position. P j In terms of frequency , the amplitude is , reflecting the fluid movement at that location. By monitoring this vibration information, the operating status and corresponding position of each nozzle can be determined.

[0026] Thus, each vibration sensor C 1 ~ C m Can sense a nozzle P j Frequency and amplitude . And the processor can extract each nozzle P 1 ~ P n The monitoring spectrum information consists of the frequency and amplitude of the nozzle. One vibration sensor can monitor multiple nozzles at the same time P 1 ~ P n , multiple vibration sensors C 1 ~ C m Cross-monitoring can be performed. Specifically, for example, refer to Figure 4 As shown, the sensor C 1 Branch pipes can be monitored E 1 and E 2 Since the entire device is a metal structure with good vibration conductivity, the sensor C 1 In fact, it can also receive E 3 , branch pipe E 5 The vibration of the nozzle on the branch pipe, of course, due to the attenuation and crosstalk caused by the long distance, the monitoring effect will not be very good, so cross monitoring can be carried out to improve the positioning accuracy. Figure 4 For example, when a sensor such as C 2 In case of failure, the adjacent sensor C 1 and C 3 Branches that can still be held responsible E 3 and E 4Monitoring is performed so that even if a sensor fails, monitoring can still be maintained, improving the reliability of the system; or when a nozzle fails, for example E 3 on P 2 ,Apart from C 2 In addition to the obvious response, C 1 and C 3 It also has a certain response, which improves the positioning accuracy of the faulty nozzle.

[0027] Among them, under ideal conditions, each nozzle P 1 ~ P n All have fixed frequencies and amplitudes. However, in actual vibration, there will be certain changes around the center frequency, causing each nozzle to P 1 ~ P n The spectrum corresponding to the vibration is broadened (such as Figure 5 Therefore, in this embodiment, each nozzle P 1 ~ P n The corresponding central vibration frequency replaces the natural frequency as the vibration information corresponding to its vibration.

[0028] Then, the processor monitors the spectrum information , determining the nozzle having a fault (S506). The fault of the nozzle includes, for example, blockage and corrosion, and the details of determining the nozzle having a fault will be described in detail later.

[0029] As described in the background technology, the nozzle of the gas silting device is prone to blockage, corrosion and other faults during use, which seriously affects the performance of the equipment. In view of this, the present invention measures the vibration at the corresponding position in real time and generates a vibration signal through multiple vibration sensors arranged in the gas silting device, and then determines the spectrum information of each vibration signal through a processor, and then determines the nozzle with fault according to the spectrum information, so as to monitor the status of each nozzle in the gas silting device in real time and locate the fault.

[0030] Optionally, the operation of the faulty nozzle is determined based on the first spectral information, including: comparing the first spectral information with the second spectral information, and determining whether there is an abnormality in the gas dredging device based on the comparison result, wherein the second spectral information is spectral information of a second vibration signal measured by the vibration sensor when the gas dredging device is in a stable working state; and when it is determined that there is an abnormality in the gas dredging device, determining the faulty nozzle based on the first spectral information and a plurality of pre-calibrated calibration information, wherein the calibration information corresponds to different nozzles respectively.

[0031] Specifically, in this embodiment, the vibration sensor can be predetermined C 1 ~ C m Specifically, when the vibration sensor C 1 ~ C m After the gas silt removal device is deployed, the gas silt removal device can be deployed to the working position to start working. After running for a period of time to a stable state, the vibration sensor is collected. C 1 ~ C m The collected vibration signal is Fourier transformed to obtain the spectrum information corresponding to each vibration sensor: ; ; ; … .

[0032] in It is i The vibration sensor collects the j The central vibration frequency of the spectrum of each nozzle, is its corresponding amplitude. Thus, the information As a vibration sensor C 1 ~ C m The corresponding reference spectrum information (ie, the second spectrum information).

[0033] The processor will then monitor the vibration signal s 1 ~ s m Corresponding monitoring spectrum information With the corresponding reference spectrum information A comparison is performed to determine whether there is any abnormality in the gas desilting device.

[0034] Furthermore, when the processor determines that the gas desilting device is abnormal, it further determines the nozzle that has failed based on the monitored spectrum information and multiple pre-calibrated calibration information. Each calibration information corresponds to a different nozzle that has failed. The calibration information will be described in detail below.

[0035] In this way, the processor first compares the monitoring spectrum information of the monitoring vibration signal with the reference spectrum information to preliminarily determine whether there is an abnormality in the nozzle of the gas dredging device. Then, if it is determined that there is an abnormality, the specific nozzle that has failed is further determined based on the monitoring spectrum information and the calibration information. In this way, when the nozzles of the gas dredging device are all working properly, it only needs to compare the monitoring spectrum information with the reference spectrum information to determine it. Therefore, it does not require too much calculation to determine that the gas dredging device is working properly, which greatly saves the consumption of calculation.

[0036] Optionally, the first spectrum information is compared with the second spectrum information, and based on the comparison result, it is determined whether there is abnormal operation of the gas dredging device, including: comparing a first amplitude corresponding to each nozzle in the first spectrum information with a second amplitude corresponding to each nozzle in the second spectrum information, and determining a deviation between the first amplitude and the second amplitude; and determining that there is an abnormality in the gas dredging device when the deviation between the first amplitude and the second amplitude is greater than a predetermined threshold.

[0037] Specifically, refer to Figure 2 As shown in the figure, when each nozzle on the branch pipe works normally, each nozzle sprays high-pressure gas normally, thus referring to Figure 5 As shown, the amplitude corresponding to the central vibration frequency of each nozzle is also normal.

[0038] refer to Figure 6 As shown, when there is a nozzle (such as nozzle P 1 ) When a part of the nozzle is blocked, the gas ejected from the nozzle is significantly weakened, and the gas ejected from other nozzles is slightly strengthened. Figure 7 As shown, with the nozzle blocked P 1 The amplitude at the corresponding central vibration frequency is significantly weakened, while the amplitudes at other central vibration frequencies are slightly enhanced.

[0039] Or refer to Figure 8 Shown, completely blocked nozzle P 1 No gas is emitted, while the gas from the other nozzles is slightly enhanced. Fig. 9As shown, in this case, the amplitude at the central vibration frequency corresponding to the clogged nozzle is almost zero, and the amplitudes at other central vibration frequencies are slightly enhanced.

[0040] Thus, the processor determines the monitoring spectrum information corresponding to the monitoring vibration signal. (i.e. the first spectrum information), the spectrum information will be monitored Amplitude and reference spectrum information at each central vibration frequency The amplitude at the corresponding central vibration frequency is compared to determine the monitoring spectrum information With reference spectrum information The deviation between the amplitude at each center vibration frequency of the monitoring spectrum information and the reference spectrum information. The maximum value among the various deviation values ​​of the amplitude at the corresponding central vibration frequency.

[0041] Then, when the deviation value is greater than a predetermined threshold, it indicates that the nozzle is blocked, resulting in a significant decrease in the amplitude at the corresponding central vibration frequency, thereby determining that the gas desilting device is abnormal.

[0042] Optionally, the calibration information is determined by the following operations: determining a target nozzle as a calibration target among multiple nozzles; blocking the target nozzle after the gas dredging device is operating stably, and after blocking the target nozzle, receiving third vibration signals from multiple vibration sensors; determining third spectrum information corresponding to the third vibration signal; and determining the calibration information corresponding to the target nozzle based on the deviation between the third spectrum information and the second spectrum information.

[0043] Specifically, according to the technical solution of the present application, the calibration information can be pre-calibrated. P 1 ~ P n A nozzle in P j (i.e., the target nozzle, where j =1~ n ) as an example, with this nozzle P j The corresponding calibration information can be determined, for example, by the following operations: First, after the gas desilting device is working stably, block the nozzle P j , and from the vibration sensor C 1 ~ C m Receive with the nozzle P j Corresponding calibration vibration signal sj 1 ~ s j m (ie the third vibration signal).

[0044] Then, for the calibration vibration signal s j 1 ~ s j m Perform Fourier transform to obtain the calibration vibration signal s j 1 ~ s j m The corresponding calibration spectrum information (i.e. the third spectrum information): ; ;

[0045] .

[0046] in It is i The vibration sensor collects the j The central vibration frequency of the spectrum of each nozzle, is its corresponding amplitude. Thus, the information As a vibration sensor C 1 ~ C m The corresponding calibrated spectrum information (ie, the third spectrum information).

[0047] Then, according to the calibrated spectrum information and reference spectrum information , determine the nozzle P j Corresponding calibration information e j : .

[0048] Thus, through the above method, it can be determined that the P 1 ~ P n Corresponding calibration information e j . Among them as e A specific example of a function can be expressed as the following formula: .

[0049] Among them, w is the preset linear proportional weight.

[0050] Further optionally, the operation of determining a faulty nozzle based on the first spectrum information and a plurality of pre-calibrated calibration information includes: determining deviation characteristic information between the first spectrum information and the second spectrum information; respectively determining similarity distances between the deviation characteristic information and each calibration information; determining calibration information matching the deviation characteristic information based on the similarity distances; and determining the nozzle corresponding to the determined calibration information as a faulty nozzle.

[0051] Specifically, in order to determine the failed nozzle, the processor determines to monitor the spectrum information (i.e., first spectrum information) and reference spectrum information Deviation feature information between : .

[0052] The processor then determines the deviation characteristic information With each calibration information e j The similarity distance between d j .

[0053] Then, the processor determines the calibration information with the smallest similarity distance as the deviation feature information Alternatively, multiple calibration information with similarity distance less than a preset threshold can be selected as deviation feature information Matching calibration information.

[0054] The processor then determines the deviation characteristic information The nozzle corresponding to the matched calibration information is determined to be the faulty nozzle.

[0055] Therefore, the present application matches the deviation characteristic information between the monitoring spectrum information and the reference spectrum information with the calibration information corresponding to different nozzles through the above method, so as to accurately determine the faulty nozzle.

[0056] Optionally, the vibration sensors are deployed on the branch pipe in an asymmetrical manner.

[0057] Specifically, refer to Figure 3 As shown, the vibration sensor C 1 ~ C mDeployed on the branch pipe in an asymmetric manner. Specifically, the vibration of the nozzle is mainly related to the distance between the nozzle and the main pipe. Due to the symmetrical design of the gas dredging device, it is inevitable that some nozzles will vibrate close to each other. Therefore, multi-sensor cross-monitoring is designed. The position of the air outlet can be accurately located by cross-comparison of the data of each sensor; at the same time, when laying out the sensors, it is necessary to avoid laying them out in the symmetrical position of the dredging device structure, so that the vibration generated by the symmetrical structure of the device is no longer the same when it reaches the sensor.

[0058] In order to ensure the monitoring accuracy and make the spectrum of each hole have sufficient differentiation, the sensor needs to have a sufficiently high sampling frequency. One sensor can monitor multiple nozzles at the same time, and the sensors should be dispersed and arranged in asymmetric positions of the gas desilting device.

[0059] In addition, according to a second aspect of this embodiment, a method for monitoring the health of a gas desilting device is provided, wherein the gas desilting device comprises: a main pipe; a branch pipe arranged along the main pipe; and a plurality of nozzles arranged along the branch pipe.

[0060] Optionally, the operation of the faulty nozzle is determined based on the first spectral information, including: comparing the first spectral information with the second spectral information, and determining whether there is an abnormality in the gas dredging device based on the comparison result, wherein the second spectral information is spectral information of a second vibration signal measured by the vibration sensor when the gas dredging device is in a stable working state; and when it is determined that there is an abnormality in the gas dredging device, determining the faulty nozzle based on the first spectral information and a plurality of pre-calibrated calibration information, wherein the calibration information corresponds to different nozzles respectively.
