Description

Technical Field

[0001] The present invention relates to the technical field of motor assembly production line operation and maintenance supervision, and in particular to a production line operation and maintenance supervision system for motor assembly. Background Art

[0002] A motor refers to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction, or converts one form of electrical energy into another form of electrical energy; an electric motor converts electrical energy into mechanical energy (commonly known as a motor), and a generator converts mechanical energy into electrical energy.

[0003] However, in the prior art, it is impossible to perform impact analysis on the production line process when the motor assembly production line is running, and it is impossible to perform production line impact warning analysis based on the impact analysis, so that the operation and maintenance supervision of the motor assembly production line is weak and timely warnings are impossible. In addition, it is impossible to perform operation coordination analysis on the production line, so that the production line operation efficiency supervision is abnormal, affecting the production line processing output.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned problems and to propose a production line operation and maintenance supervision system for motor assembly.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] The production line operation and maintenance supervision system for motor assembly includes an operation and maintenance supervision platform, which is connected to the production line process impact analysis unit, impact warning analysis unit, operation coordination analysis unit and stability analysis unit;

[0008] The production line process impact analysis unit performs process impact analysis on the motor assembly production line, divides the motor assembly production line into i production line processes, where i is a natural number greater than 1, obtains the motor components processed by each production line process during the historical production line operation period, and collects the corresponding motor fault parameters according to the motor parts, and matches the motor components with the corresponding motor fault parameters, collects the production line process impact data of the motor assembly production line, obtains the production line process impact analysis coefficient based on the production line process impact data analysis, and divides the production line process into a high-impact process or a low-impact process by comparing the production line process impact analysis coefficient;

[0009] The impact warning analysis unit performs production line process impact warning analysis on the motor assembly production line, collects the time difference data and value deviation data of the motor assembly production line, generates a production line warning control signal or a production line warning normal signal based on the threshold comparison, and sends it to the operation and maintenance supervision platform;

[0010] The operation coordination analysis unit performs operation coordination analysis on the motor assembly production line, obtains the processing interval data and processing speed data of the motor assembly production line, generates an inefficient coordination signal or an efficient coordination signal according to the threshold comparison, and sends it to the operation and maintenance supervision platform;

[0011] The stability analysis unit performs stability analysis on the motor assembly production line, collects the normal speed data and abnormal speed data of the motor assembly production line, generates a stability risk signal or a stability qualification signal based on threshold comparison, and sends it to the operation and maintenance supervision platform.

[0012] As a preferred embodiment of the present invention, the production line process influencing data includes the probability that the processing time period of the motor component corresponding to the production line process belongs to the same batch and the probability that it belongs to different batches when the motor component corresponding to the motor component fails during the real-time operation of the motor assembly production line, the failure rate reduction span value of the same motor component corresponding to the processed motors of different batches after the production line process of the corresponding motor component is adjusted after the motor fails during the real-time operation of the motor assembly production line, and the probability of the same type of failure of the corresponding motor component continuing to occur after operation and maintenance during the floating stage of the production line process execution speed during the real-time operation of the motor assembly production line;

[0013] Compare the production line process impact analysis coefficient of the motor assembly production line with the production line process impact analysis coefficient threshold:

[0014] If the production line process impact analysis coefficient of the motor assembly production line exceeds the production line process impact analysis coefficient threshold, the current production line process is marked as a high-impact process; if the production line process impact analysis coefficient of the motor assembly production line does not exceed the production line process impact analysis coefficient threshold, the current production line process is marked as a low-impact process, and the name or number of the low-impact process is sent to the operation and maintenance supervision platform.

[0015] As a preferred embodiment of the present invention, the time difference data and the numerical deviation data are respectively the time setting deviation of the operation monitoring cycle corresponding to the high-impact process and the low-impact process during the operation of the motor assembly production line, and the numerical deviation value of the average buffer time for generating early warning signals corresponding to the high-impact process and the low-impact process within the time setting deviation of the operation monitoring cycle.

[0016] As a preferred embodiment of the present invention, if the time difference data is not within the time setting deviation threshold range, or the numerical deviation data does not exceed the buffer time numerical deviation threshold, a production line early warning control signal is generated;

[0017] If the time difference data is within the time setting deviation threshold range, and the numerical deviation data exceeds the buffer time numerical deviation threshold, a normal production line warning signal is generated.

[0018] As a preferred embodiment of the present invention, the processing interval data and the processing speed data are respectively the reciprocating floating span value of the interval between the start and end of any adjacent production line processes during the operation of the motor assembly production line and the numerical floating amount of the processing speed of the current batch production line when the processing interval of any adjacent production line processes during the operation of the motor assembly production line is abnormal.

[0019] As a preferred embodiment of the present invention, if the processing interval data exceeds the interval time reciprocating floating span value threshold, or the processing speed data exceeds the processing speed numerical floating amount threshold, an inefficient coordination signal is generated;

[0020] If the processing interval data does not exceed the interval time reciprocating floating span value threshold, and the processing speed data does not exceed the processing speed numerical floating amount threshold, an efficient coordination signal is generated.

[0021] As a preferred embodiment of the present invention, the normal speed data and the abnormal speed data are respectively the frequency of a decrease in the production line processing speed when there are no interval abnormalities in any adjacent production line processes during the operation of the motor assembly production line, and the frequency of no fluctuation in the production line processing speed when there are abnormal intervals between adjacent production line processes during the operation of the motor assembly production line.

[0022] As a preferred embodiment of the present invention, if the normal speed data exceeds the falling frequency threshold, or the abnormal speed data does not exceed the non-floating frequency threshold, a stability risk signal is generated;

[0023] If the normal speed data does not exceed the falling frequency threshold and the abnormal speed data exceeds the no-floating frequency threshold, a stability qualified signal is generated.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. In the present invention, a process impact analysis is performed on the motor assembly production line. According to the analysis of the impact of each process in the motor assembly production line on the operation of the assembled motor, the supervision accuracy of each process of the motor assembly production line is improved, and at the same time, it can be ensured that the production line can be adjusted in time if a fault occurs after the motor is assembled; a production line process impact early warning analysis is performed on the motor assembly production line to determine whether the early warning efficiency of different types of production line processes meets the actual production line operation requirements when the actual processing is abnormal, so as to avoid the low efficiency of the production line early warning and the inability to timely guarantee the operation monitoring efficiency of the motor assembly production line, and at the same time reduce the pertinence of the process operation and maintenance when the motor assembly production line operates abnormally, resulting in low production and processing efficiency of the entire production line.

[0026] 2. In the present invention, an operation coordination analysis is performed on the motor assembly production line, and the operation efficiency of the production line is monitored in real time to see whether it meets the current production and processing needs, so as to avoid the motor assembly production line from being reduced in operation efficiency due to low production line supervision accuracy when there is no fault, affecting the processing progress and failing to coordinate and control each process of the production line in time, which is likely to increase the impact of abnormal production line operation; a stability analysis is performed on the motor assembly production line, and when it is determined that the operation coordination efficiency of the motor assembly production line meets the demand, the qualified operation stability is analyzed to improve the supervision of the production line, and at the same time, timely operation and maintenance can be performed when the production line operates abnormally, thereby improving the operation efficiency of the motor assembly production line.

[0029] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] See also Figure 1 As shown, the production line operation and maintenance supervision system for motor assembly includes an operation and maintenance supervision platform, which is communicatively connected to a production line process impact analysis unit, an impact warning analysis unit, an operation coordination analysis unit, and a stability analysis unit;

[0032] The operation and maintenance supervision platform generates a production line process impact analysis signal and sends the production line process impact analysis signal to the production line process impact analysis unit. After receiving the production line process impact analysis signal, the production line process impact analysis unit conducts process impact analysis on the motor assembly production line. According to the impact analysis of each process in the motor assembly production line on the operation of the assembled motor, the supervision accuracy of each process of the motor assembly production line is improved. At the same time, it can ensure that the production line can be adjusted in time if a fault occurs after the motor is assembled.

[0033] The motor assembly production line is divided into i production line processes, where i is a natural number greater than 1. The motor components processed by each production line process during the historical production line operation period are obtained. At the same time, the corresponding motor fault parameters are collected according to the motor parts, and the motor components are matched with the corresponding motor fault parameters. The motor fault parameters are expressed as parameters such as temperature and noise decibel value;

[0034] When a motor component corresponding to a motor that has been processed during the real-time operation of the motor assembly production line fails, the probability that the motor component's processing period in the production line process belongs to the same batch and the probability that it belongs to a different batch is obtained, and the probability that the motor component's processing period in the production line process belongs to the same batch and the probability that it belongs to a different batch is obtained, and the probability that the motor component's processing period belongs to the same batch and the probability that it belongs to a different batch is obtained, and the failure rate reduction span value of the same motor component corresponding to the motors of different batches is obtained after the production line process of the motor that has been processed fails during the real-time operation of the motor assembly production line is adjusted, and the failure rate reduction span value of the same motor component corresponding to the motors of different batches is obtained, and the failure rate reduction span value of the same motor component corresponding to the motors of different batches is marked as KDZi;

[0035] Obtain the probability of the same type of faults of the corresponding motor parts continuing to occur after operation and maintenance during the floating stage of the production line process execution speed during the real-time operation of the motor assembly production line, and mark the probability of the same type of faults of the corresponding motor parts continuing to occur after operation and maintenance during the floating stage of the production line process execution speed during the real-time operation of the motor assembly production line as YVGi;

[0036] By formula Obtain the production line process impact analysis coefficient XCi of the motor assembly production line, where fj1, fj2 and fj3 are the preset proportional coefficients of the probability value ratio, the failure rate reduction span value and the continuous occurrence probability, respectively, and β is used as the error correction factor with a value of 1.25; the above collected data are uniformly marked as production line process impact data;

[0037] Compare the production line process impact analysis coefficient XCi of the motor assembly production line with the production line process impact analysis coefficient threshold:

[0038] If the production line process impact analysis coefficient XCi of the motor assembly production line exceeds the production line process impact analysis coefficient threshold, the corresponding production line process impact analysis of the motor assembly production line is determined to be abnormal, the current production line process is marked as a high-impact process, and the name or number of the high-impact process is sent to the operation and maintenance supervision platform;

[0039] If the production line process impact analysis coefficient XCi of the motor assembly production line does not exceed the production line process impact analysis coefficient threshold, the production line process impact analysis corresponding to the motor assembly production line is determined to be normal, the current production line process is marked as a low-impact process, and the name or number of the low-impact process is sent to the operation and maintenance supervision platform;

[0040] At the same time, an impact warning analysis signal is generated and sent to the impact warning analysis unit;

[0041] After receiving the impact warning analysis signal, the impact warning analysis unit performs a production line process impact warning analysis on the motor assembly production line to determine whether the warning efficiency of different types of production line processes meets the actual production line operation requirements when the actual processing is abnormal, so as to avoid the low efficiency of the production line warning and the inability to timely ensure the operation monitoring efficiency of the motor assembly production line. At the same time, it reduces the pertinence of the process operation and maintenance when the motor assembly production line operates abnormally, resulting in low production and processing efficiency of the entire production line;

[0042] The time setting deviation of the operation monitoring cycle corresponding to the high-impact process and the low-impact process in the operation of the motor assembly production line and the numerical deviation value of the average buffer time of the warning signal corresponding to the high-impact process and the low-impact process within the time setting deviation of the operation monitoring cycle are obtained, and the time setting deviation of the operation monitoring cycle corresponding to the high-impact process and the low-impact process in the operation of the motor assembly production line and the numerical deviation value of the average buffer time of the warning signal corresponding to the high-impact process and the low-impact process within the time setting deviation of the operation monitoring cycle are marked as time difference data and numerical deviation data, and compared with the time setting deviation threshold range and the buffer time numerical deviation threshold respectively:

[0043] If the time setting deviation of the operation monitoring cycle corresponding to the high-impact process and the low-impact process during the operation of the motor assembly production line is not within the time setting deviation threshold range, or the numerical deviation of the average buffer time generated by the warning signal corresponding to the high-impact process and the low-impact process within the time setting deviation of the operation monitoring cycle does not exceed the buffer time numerical deviation threshold, then the production line process impact warning analysis in the motor assembly production line is determined to be unqualified, and a production line warning control signal is generated and sent to the operation and maintenance supervision platform. After receiving the production line warning control signal, the operation and maintenance supervision platform sets the monitoring cycle for each production line process corresponding to the motor assembly production line, and sets different warning signal detection time lengths according to different types of production line processes, that is, the monitoring cycle of the high-impact process needs to be shorter than that of the low-impact process, and ensure that the warning signal detection time lengths of the high-impact process and the low-impact process are within the normal set time length range;

[0044] If the time setting deviation of the operation monitoring cycle corresponding to the high-impact process and the low-impact process during the operation of the motor assembly production line is within the time setting deviation threshold range, and the numerical deviation of the average buffer time generated by the warning signal corresponding to the high-impact process and the low-impact process within the time setting deviation of the operation monitoring cycle exceeds the buffer time numerical deviation threshold, then it is determined that the production line process impact warning analysis in the motor assembly production line is qualified, and a normal production line warning signal is generated and sent to the operation and maintenance supervision platform;

[0045] The operation and maintenance supervision platform generates an operation coordination analysis signal and sends the operation coordination analysis signal to the operation coordination analysis unit. After receiving the operation coordination analysis signal, the operation coordination analysis unit performs operation coordination analysis on the motor assembly production line, and monitors in real time whether the operation efficiency of the production line meets the current production and processing requirements, so as to avoid the motor assembly production line still being reduced in efficiency due to low production line supervision accuracy when there is no fault, affecting the processing progress and failing to coordinate and control each process of the production line in time, which is easy to increase the impact of abnormal production line operation;

[0046] Obtain the reciprocating floating span value of the interval time between the start and end of any adjacent production line processes during the operation of the motor assembly production line and the numerical floating amount of the processing speed of the current batch of production lines when the processing interval of any adjacent production line processes during the operation of the motor assembly production line is abnormal, and mark the reciprocating floating span value of the interval time between the start and end of any adjacent production line processes during the operation of the motor assembly production line and the numerical floating amount of the processing speed of the current batch of production lines when the processing interval of any adjacent production line processes during the operation of the motor assembly production line is abnormal as processing interval data and processing speed data, respectively, and compare them with the interval time reciprocating floating span value threshold and the processing speed numerical floating amount threshold, respectively: wherein, the processing interval abnormality is represented by the interval time of adjacent production line processes exceeding the set time threshold for two or more consecutive times;

[0047] If the reciprocating floating span value of the interval time between the start and end of any adjacent production line process processing during the operation of the motor assembly production line exceeds the reciprocating floating span value threshold of the interval time, or the numerical fluctuation amount of the current batch of production line processing speed exceeds the numerical fluctuation amount threshold of the processing speed when any adjacent production line process processing interval during the operation of the motor assembly production line is abnormal, then the operation coordination analysis of the motor assembly production line is determined to be inefficient, and an inefficient coordination signal is generated and sent to the operation and maintenance supervision platform; after receiving the inefficient coordination signal, the operation and maintenance supervision platform will conduct real-time monitoring of the production line process execution time deviation and the overall production line execution time deviation of the motor assembly production line, and perform duration control when monitoring is abnormal;

[0048] If the reciprocating floating span value of the interval time between the start and end of any adjacent production line process processing during the operation of the motor assembly production line does not exceed the reciprocating floating span value threshold of the interval time, and the numerical fluctuation amount of the current batch production line processing speed does not exceed the processing speed numerical fluctuation amount threshold when any adjacent production line process processing interval is abnormal during the operation of the motor assembly production line, then it is determined that the operation coordination analysis of the motor assembly production line is efficient, and an efficient coordination signal is generated and sent to the operation and maintenance supervision platform;

[0049] At the same time, a stability analysis signal is generated and sent to the stability analysis unit. After receiving the stability analysis signal, the stability analysis unit performs stability analysis on the motor assembly production line. When it is determined that the operation coordination efficiency of the motor assembly production line meets the requirements, the qualified operation stability is analyzed to improve the supervision of the production line. At the same time, operation and maintenance can be carried out in time when the production line is operating abnormally, thereby improving the operation efficiency of the motor assembly production line.

[0050] The frequency of the decrease in the processing speed of the production line when there is no abnormal interval between any adjacent production line processes during the operation of the motor assembly production line and the frequency of the non-floating processing speed of the production line when there is an abnormal interval between adjacent production line processes during the operation of the motor assembly production line are obtained, and the frequency of the decrease in the processing speed of the production line when there is no abnormal interval between any adjacent production line processes during the operation of the motor assembly production line and the frequency of the non-floating processing speed of the production line when there is an abnormal interval between adjacent production line processes during the operation of the motor assembly production line are marked as normal speed data and abnormal speed data, respectively, and compared with the decrease frequency threshold and the non-floating frequency threshold, respectively:

[0051] If the frequency of the decrease in the production line processing speed when there are no interval abnormalities in any adjacent production line processes during the operation of the motor assembly production line exceeds the decrease frequency threshold, or the frequency of the non-floating production line processing speed when there are abnormal intervals between adjacent production line processes during the operation of the motor assembly production line does not exceed the non-floating frequency threshold, then the stability analysis of the motor assembly production line is determined to be abnormal, a stability risk signal is generated and sent to the operation and maintenance supervision platform. After receiving the stability risk signal, the operation and maintenance supervision platform supervises each production line process of the motor assembly production line, and when the delay control amount of the corresponding production line process processing interval is reduced, an early warning is issued and the current production line process is used as an operation and maintenance detection process;

[0052] If the frequency of the decrease in the processing speed of the production line when there is no interval abnormality in any adjacent production line process during the operation of the motor assembly production line does not exceed the decrease frequency threshold, and the frequency of the non-floating processing speed of the production line when there is an interval abnormality in the adjacent production line process during the operation of the motor assembly production line exceeds the non-floating frequency threshold, then the stability analysis of the motor assembly production line is determined to be normal, a stability qualified signal is generated and the stability qualified signal is sent to the operation and maintenance supervision platform;

[0053] The above formulas are obtained by collecting a large amount of data and performing software simulation, and a formula close to the actual value is selected. The coefficients in the formula are set by technicians in this field according to actual conditions;

[0054] When the present invention is in use, the production line process impact analysis unit performs process impact analysis on the motor assembly production line, divides the motor assembly production line into i production line processes, i is a natural number greater than 1, collects the production line process impact data of the motor assembly production line, obtains the production line process impact analysis coefficient according to the production line process impact data analysis, and divides the production line process into a high-impact process or a low-impact process by comparing the production line process impact analysis coefficients; the impact warning analysis unit performs production line process impact warning analysis on the motor assembly production line, collects the time difference data and the numerical deviation data of the motor assembly production line, generates a production line warning control signal or a production line warning normal signal according to the threshold comparison, and sends it to the operation and maintenance supervision platform; the operation coordination analysis unit performs operation coordination analysis on the motor assembly production line, obtains the processing interval data and the processing speed data of the motor assembly production line, generates an inefficient coordination signal or an efficient coordination signal according to the threshold comparison, and sends it to the operation and maintenance supervision platform; the stability analysis unit performs stability analysis on the motor assembly production line, collects the normal speed data and the abnormal speed data of the motor assembly production line, generates a stability risk signal or a stability qualified signal according to the threshold comparison, and sends it to the operation and maintenance supervision platform.
