Example 1
First, the application background of the operation monitoring method provided by the invention is briefly described.
Generally, a gas-liquid transmission device in a five-axis linkage double-pendulum milling head is currently installed inside the milling head, for example, the patent number is: the specific structure shown in CN114654007a, we found that once the gas-liquid transmission device is damaged, the whole five-axis linkage double-pendulum milling head needs to be disassembled for replacement in the practical use process. For the above situation, we can externally arrange the gas-liquid transmission device and design a specific operation monitoring method to timely find out whether the gas-liquid transmission device is in an abnormal operation state, for example, the gas-liquid transmission device has gas-liquid leakage.
As shown in fig. 2 and 3, in the present invention, the gas-liquid transmission device is a rotary distributor 200, and since the conventional rotary distributor 200 is not easy to monitor when being arranged inside the milling head, in order to monitor the rotary distributor 200 in real time, a five-axis linkage double pendulum milling head 100 is provided with an external rotary distributor, and the rotary distributor 200 comprises: a housing 203 connected to the driving mechanism 400, and a gas-liquid transmission member 204 in the housing 203, wherein the gas-liquid transmission member 204 is communicated with the inside of the milling head through a pipeline to form a gas-liquid flow passage (fig. 2 shows an external schematic diagram of the rotary distributor 200 and the milling head main shaft 300).
As shown in fig. 2 and 3, and as shown in the schematic structural diagram of a five-axis linkage double-pendulum milling head and the cross-sectional view of a rotary distributor, the rotary distributor 200 bears the main gas-liquid transmission work, so that the five-axis linkage double-pendulum milling head 100 can monitor the operation of the rotary distributor 200 by externally arranging the rotary distributor 200, thereby realizing the operation monitoring of the five-axis linkage double-pendulum milling head 100, solving the problems that the current gas-liquid transmission device is seriously leaked, even after a period of leakage, the current gas-liquid transmission device is not noticed in advance, and the whole production plan is not controlled by a producer.
Next, based on structural improvement and optimization, the invention provides an operation monitoring method capable of timely monitoring the operation state of a five-axis linkage double-pendulum milling head, please refer to a flow chart of the operation monitoring method of the five-axis linkage double-pendulum milling head provided by the embodiment shown in fig. 1, wherein the operation monitoring method comprises the following steps:
s100: traversing a device state database; the device state database comprises at least: a factory building number, all rotary distributor numbers under each factory building number, and the remaining service life of the rotary distributor 200 corresponding to the rotary distributor number;
The structure of the equipment state database is shown in table 1, and the equipment state database is established by technicians through early observation, data acquisition and other modes, and the main purpose of the equipment state database is to obtain the residual service lives of different rotary distributors 200 under different plants through static data analysis.
Table 1 device status database structure example
In view of the example of the equipment status database structure shown in table 1, the monitoring of the rotary distributor 200 under each plant number is mainly performed in the basic unit of the plant, and because the processing content performed by each plant is different, the medium through which each rotary distributor 200 flows is different, so that different monitoring blocks need to be established based on different plants. Explanation about the contents in table 1, wherein the factory building number is constituted by space+number; the rotary distributor number is composed of fpq+number numbers, so X and n in the table are used to refer to any number, and the number content is not specifically limited.
S200: acquiring the remaining service life of each rotary distributor 200 in real time;
The device state database can be established to monitor the remaining service lives of the plurality of rotary distributors 200, and then, whether the first alarm information is triggered or not is judged by acquiring the obtained values of the remaining service lives in real time.
S300: if the remaining service life is less than or equal to the preset time threshold, the rotary distributor 200 is marked as the rotary distributor to be replaced, and first alarm information is sent, wherein the first alarm information comprises the number of the rotary distributor to be replaced and the plant number of the plant where the rotary distributor to be replaced is located.
In the actual use process, the execution main body of the operation monitoring method can be an upper computer, a tablet personal computer, a mobile phone or other service terminals; when the corresponding system judging module judges that any residual service life is smaller than or equal to a preset time threshold, first alarm information is sent out, the first alarm information can be displayed on a screen of an upper computer, a tablet personal computer or a mobile phone in an information mode, and the specific mode is not limited specifically.
It should be noted that the setting of the preset time threshold needs to be set according to the actual situation, and may be set to 1h or 12h, and in this embodiment, 12h is selected as the preset time threshold, which is to provide a technician with sufficient time to prepare for replacing the rotary distributor 200 of the corresponding rotary distributor to be replaced, and the setting of the remaining service life is generally performed based on the installation time of the rotary distributor 200 and on the basis of the previous data acquisition, and the total service lives of the rotary distributors 200 in different factory numbers may be different, but the setting of the remaining service lives may be the same, which of course may also be differently set according to different service environments.
In addition, in a preferred embodiment, in addition to the foregoing static data analysis and monitoring method, in order to avoid some emergency situations, the present invention further includes a dynamic inspection method, and specifically, the operation and monitoring method further includes:
A1, acquiring all the rotary distributor numbers with the residual service lives within a preset time range, and marking the rotary distributor 200 corresponding to the rotary distributor numbers as a rotary distributor to be monitored;
Specifically, the preset time range needs to be set with reference to a preset time threshold, for example, the preset time threshold is 12h, and the preset time range needs to be set before the preset time threshold and can be set to 48h-24h, so that dynamic inspection can be formed before the first alarm information is not triggered.
A2, acquiring a real-time operation image of the rotary distributor to be monitored;
The real-time running image can be acquired through the image acquisition device, the image acquisition device can use a simple camera shooting device, and as the camera is installed in each factory building, the real-time running image of the rotary distributor to be monitored can be acquired through image acquisition of the camera.
Step A3, based on the real-time running image and the first recognition module, obtaining a recognition result, wherein the recognition result comprises: a first recognition result or a second recognition result;
Wherein the first recognition result is used for reflecting that the rotary distributor 200 has abnormal operation risk, and the second recognition result is used for reflecting that the rotary distributor 200 operates normally;
after the real-time operation image is acquired, the first identification module is used for identifying the real-time operation image to obtain a corresponding identification result; specifically, the first recognition module may be obtained by training based on a first neural network and performing a test through a first training set and a first test set, where the first training set and the first test set each include a plurality of groups of sample images (because the present invention is directed to monitoring of leakage problems of the rotary distributor 200, the sample images mainly include pictures of different leakage degrees generated by different rotary distributors 200) of the rotary distributor 200, where there is a risk of abnormal operation of the rotary distributor 200 corresponding to the first recognition result, and sample images of normal operation of the rotary distributor 200 corresponding to the second recognition result; and outputting a corresponding identification result according to the operation state of the rotary distributor 200 displayed by the real-time operation image.
And A4, marking the rotary distributor to be monitored, the identification result of which is the first identification result, as an operation abnormal rotary distributor, and sending out second alarm information, wherein the second alarm information comprises the number of the operation abnormal rotary distributor and the plant number of the plant where the operation abnormal rotary distributor is located, and the second alarm information is used for prompting that the corresponding operation abnormal rotary distributor needs to be replaced.
The rotary distributor to be monitored, which corresponds to the real-time operation image with the identification result being the first identification result, is marked as an abnormal operation rotary distributor, and meanwhile, second alarm information is triggered, wherein the second alarm information has the same alarm prompting effect as the first alarm information, and the used transmission form is the same.
In a preferred embodiment, as shown in fig. 4, after the second alarm information is sent, the method further comprises the steps of:
Step B1, storing the abnormal operation rotation distributor into a storage subarea corresponding to a factory building number of a factory building where the abnormal operation rotation distributor is located in a temporary storage area; the temporary storage area is divided into a plurality of storage subareas in advance according to the factory building number;
In actual use, the process of placing the rotary distributor to be replaced into the corresponding storage subarea is also included (the process of placing the rotary distributor to be replaced into the corresponding storage subarea is used for observing whether the current rotary distributor is reusable or not, and the rotary distributor is generally replaced directly, but special cases are not excluded), but since the rotary distributors 200 which are abnormal when the preset time threshold is not reached are mainly analyzed later, only the rotary distributor which is abnormal in operation is stored.
Step B2, when the number of the rotary distributors 200 in the storage subarea is larger than a preset number, calculating an average value of actual service lives of the rotary distributors 200 in each storage subarea according to the corresponding installation time and the sending time of the second alarm information;
Since the equipment status database is only constructed according to the previous data collection of the technician at the beginning of the establishment, in order to establish a more accurate equipment status database, the remaining service life in the equipment status database needs to be updated by monitoring the obtained actual data, and this also requires the equipment status database to further include the installation time of each of the rotary distributors 200.
In the earlier data collection, the model number of each rotary distributor 200 in the factory number SPACE001 and the processing task to be executed are the same, so that the total service life of each rotary distributor 200 is the same, so that the remaining service life of each rotary distributor 200 needs to be calculated according to the installation time of different rotary distributors 200, for example, the total service lives of FPQ1001 and FPQ1002 are 60 days (1440 h), but the installation time of the rotary distributor 200 with the number FPQ1001 is 15 days earlier than that of the rotary distributor 200 with the number FPQ1002, and then the remaining service life of FPQ1002 is 367h when the remaining service life of FPQ1001 is 7h.
As can be seen from a combination of the foregoing, the calibration of the overall remaining life is based entirely on the total life value, and if enough rotating dispensers 200 are found to be replaced before the preset time threshold, a significant hysteresis in the remaining life calculated from the initial total life in the device status database is present and needs to be updated in time.
For example, it is found through dynamic inspection that there are 20 rotary distributors 200 in SPACE001, and when there are 10 rotary distributors 200 in the SPACE, that is, the number of rotary distributors 200 in the storage area corresponding to SPACE001 is greater than a preset number (the preset number needs to be set according to the total number of rotary distributors 200 in different SPACEs, for example, 10 may be selected), the remaining service life needs to be recalculated, more precisely, the total service life needs to be recalculated, and then the remaining service life needs to be updated.
Further, in updating the remaining service life, it is necessary to calculate an average value of the actual service life of the rotary distributor 200 in each storage sub-area.
For example, in the aforementioned established scenario, "20 rotary distributors 200 in SPACE001 are found to have advanced damage to 10 rotary distributors 200 in the factory through dynamic inspection", the actual service life can be calculated according to the installation time of the corresponding 10 rotary distributors 200 that are damaged in advance and the time of sending the second alarm information, so that the remaining service life is more accurate, the average value of the actual service lives of the plurality of rotary distributors 200 that are damaged in advance needs to be obtained to update the total service life previously used for calculating the remaining service life, and then a new remaining service life value is obtained.
And B3, updating the residual service life value in the equipment state database according to the average value, and adjusting the corresponding preset time range.
In combination with the foregoing, it is known that the value of the remaining service life in the equipment status database can be updated by the average value of the actual service life, and accordingly, the preset time range needs to be correspondingly adjusted while the remaining service life is updated, and the preset time range can be adjusted by expanding or shrinking according to the extension or shortening of the remaining service life, which is not particularly limited.
In a preferred embodiment, since the corresponding work task is being performed in each plant, the large-area rotary distributor 200 is prevented from being marked as a rotary distributor to be monitored in the plant due to consideration of the whole production cycle, and the following steps are further included after the step of marking the rotary distributor 200 corresponding to the rotary distributor number as a rotary distributor to be monitored:
step C1, acquiring the number of the rotary distributors to be monitored corresponding to each plant number;
And C2, when the number of the rotary distributors to be monitored within the preset time period is judged to be larger than a monitoring number threshold, sending out first prompt information, wherein the first prompt information comprises factory building numbers when the number of the rotary distributors to be monitored is larger than the monitoring number threshold.
As understood by referring to the actual scenario, for example, 20 rotary distributors 200 in SPACE001 are obtained through the foregoing steps, all the rotary distributors 200 corresponding to the rotary distributor numbers are marked as rotary distributors to be monitored, and then 11 rotary distributors 200 under the factory are marked as rotary distributors to be monitored, if the threshold of the monitoring quantity is set to 10, then a first prompt message is triggered, and the first prompt message is used to prompt that a plurality of rotary distributors 200 under the factory number have been brought into a state to be monitored, and there is a risk of continuous damage in a short period of time, and a new rotary distributor 200 needs to be paid attention or prepared in advance for timely replacement; in addition, since the time that the rotary dispenser 200 is marked as the rotary dispenser to be monitored is not fixed, the number of rotary dispensers to be monitored is also monitored for a set period of time or cycle, and the preset period of time may be 1h, meaning that the number of rotary dispensers to be monitored is collected once or more every 1h.
At this time, as will be understood in connection with fig. 4, there are shown a plurality of plants (plant 1, plant 2.. plant m);
The factory building 1 comprises a rotating distributor which operates normally and an abnormally-operated rotating distributor which is identified by a first identification module, the factory building 1 triggers second alarm information at the moment, and the abnormally-operated rotating distributor is correspondingly placed in a sub-storage area of the corresponding factory building 1 in a pause area; the factory building 2 comprises a rotating distributor and a plurality of rotating distributors to be monitored, wherein the rotating distributors to be monitored are normally operated, and the quantity of the rotating distributors to be monitored is larger than a monitoring quantity threshold value (the monitoring quantity threshold value corresponds to in fig. 4 at the moment), so that first prompt information is triggered at the moment; the factory building m contains a rotary distributor which operates normally, a rotary distributor to be monitored and a rotary distributor to be replaced, and the existence of the rotary distributor to be replaced causes the factory building m to trigger first alarm information.
In a preferred embodiment, it is desirable to focus and analyze spinner dispensers 200 in plants that are frequently experiencing abnormal operation of the spinner dispensers or spinner dispensers 200 that have operating anomalies far less than the remaining useful life while preventing large area damage.
In view of this, the operation monitoring method further includes:
Step D1, selecting at least one abnormal operation rotation distributor in each storage subarea to perform a waterway simulation test, and confirming a leakage point of the abnormal operation rotation distributor;
the abnormal operation rotary distributor in each storage subarea can be used as an analysis sample of the factory building, but in the actual selection process, the analysis sample can be preferably selected as the rotary distributor 200 with the abnormal operation time far smaller than the residual service life, for example, after the rotary distributor 200 with the serial number of FPQ1008 is marked as the rotary distributor to be monitored, a technician finds that the real operation image is recognized as a first recognition result by the first recognition module, and then the serial number of rotary distributor 200 can be preferably selected.
Specifically, the waterway simulation test is performed by a technician after selecting a suitable analysis sample; the main reason for implementing the waterway simulation test is that the confirmation of the leakage point cannot be performed completely depending on the real-time operation image acquired by the image acquisition device, and the real-time operation image can only reflect the state and cannot lock the leakage point at the first time, so that a specific waterway simulation test is required.
The waterway simulation test comprises the following steps: (1) Confirming a factory building number corresponding to the analysis sample, and confirming a circulation medium used for the waterway simulation test according to the factory building number; (2) confirming that there is no residual medium in the analysis sample; (3) Connecting a pipeline for the waterway simulation test with a water inlet of the analysis sample, and then introducing a corresponding flow medium into the analysis sample; (4) And observing whether the analysis sample really has leakage or not in the process of introducing the corresponding flowing medium, and marking the leakage point if the leakage problem exists.
And D2, carrying out structural disassembly analysis on the abnormal operation rotating distributor with the confirmed leakage point.
It should be noted that the determination of the leakage point can only initially check whether the rotary distributor 200 has leakage, eliminate erroneous judgment of the first identification module, and confirm the range of the leakage point of the rotary distributor 200, for example, whether the leakage point is still at the water inlet, the body of the rotary distributor 200, etc., but the problem of specifically causing leakage is still required to be analyzed by structural disassembly.
In a preferred embodiment, the structural optimization of rotary distributor 200 first requires that the greatest cause of leakage of rotary distributor 200 be specified. Specifically, the rotary distributor 200 is provided with a plurality of sealing rings 202, and the sealing rings 202 are used for ensuring the air tightness of a plurality of gas-liquid communication cavities 201 formed between the shell 203 and the gas-liquid transmission piece 204, so that once the sealing rings are worn, the rotary distributor 200 is easy to leak.
The step of performing structural disassembly analysis on the abnormal operation rotating distributor confirmed by the leakage point specifically comprises the following steps:
Step D21, splitting the abnormal operation rotation distributor confirmed by the leakage point;
In the process of splitting, the quick splitting of the abnormal operation rotary distributor can be realized by means of corresponding tools.
Step D22, determining whether the seal ring 202 in the abnormal operation rotation distributor is in an abnormal state, where the abnormal state includes: deformation and abrasion;
In the actual judgment process, the abnormal state of the seal ring 202 can be obtained by the observation of the technician, because the deformation or abrasion of the seal ring 202 is easily found.
Step D23, recording the installation position and the using time of the sealing ring 202 in an abnormal state on the rotary distributor 200;
Step D24, establishing a configuration database of the rotary distributor 200, wherein the configuration database at least comprises: the rotary distributor number, seal ring type, length of use, and type of flow medium with which the seal ring 202 is in contact when mounted to the corresponding rotary distributor 200.
The third and fourth steps are mainly to monitor the damage degree of the seal ring 202 in the rotary distributor 200, and then to optimize the structure after accumulating certain analysis data; specifically, the structure of the configuration database that establishes rotary distributor 200 is shown in table 2 below.
Table 2 configuration database structure example of rotary distributor
As can be seen from table 2 above, different types of seal rings 202 are corresponding to different rotary distributors 200, and the seal rings 202 of different types have different wear resistance, so that the performance of the seal rings 202 of different types can be compared with each other by establishing a configuration database, and the development and design of the rotary distributor 200 can be guided.
In a preferred embodiment, after determining whether the seal ring 202 in the abnormal operation rotary distributor is in an abnormal state, the method further comprises the steps of:
step E1, when confirming that the abnormal state exists in the sealing ring 202 in the abnormal operation rotating distributor, replacing the corresponding sealing ring 202, and carrying out waterway simulation test again;
E2, after the waterway simulation test result is qualified, storing the corresponding rotary distributor 200 in a standby area corresponding to the factory building number of the factory building where the rotary distributor 200 is located; the temporary storage area is divided into a plurality of standby subareas in advance according to the factory building number.
Considering the cost problem, the rotary distributor 200 in the abnormal operation state can be put into use again after the waterway simulation test result is qualified by replacing the seal ring 202, at this time, the corresponding rotary distributor 200 can be stored in a standby area to wait for a standby subarea corresponding to the plant number of the plant where the rotary distributor 200 is located, and the rotary distributor 200 can be replaced when the plant with the corresponding plant number needs to be replaced; at this time, referring to fig. 4, the spare area is divided into spare sub-areas corresponding to the plant 1, and the normal rotation distributor is stored in the spare sub-areas at this time, so when the rotation distributor 200 needs to be replaced in the plant 1, the normal rotation distributor stored in the spare sub-areas can be selected.
