The above-mentioned serial numbers of the embodiments of the present invention are merely for description and do not represent the merits of the embodiments.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
The embodiment of the invention provides an information acquisition method, which is applied to information acquisition equipment. Referring to fig. 1, the method includes the steps of:
step 101, obtaining working parameters of each period in historical operation of at least one reference device to obtain first data, and obtaining reference remaining service life corresponding to the first data.
Wherein the first data is used to characterize a device technology capability of the at least one reference device; the first data includes a plurality of sets of operating parameters. Here, each period may be set according to an operating frequency of a reference device, for example, the reference device may be an oven, and a user uses the oven once a day, so that the information obtaining device may analyze the historical operating parameters after obtaining the historical operating parameters of the oven, that is, the operating parameters, and obtain the daily operating parameters of the oven based on the historical operating parameters. Of course, the setting manner of each period in the embodiment of the present invention is not specifically limited, so as to implement the information obtaining method provided by the present invention.
The device technical performance of the reference device includes one or more of an operational parameter of the reference device, a structural characteristic of the reference device, a technical specification of the reference device, and a level of accuracy of the reference device. Wherein the operating parameters of the reference device may include parameters during historical operation of the reference device. When the number of reference devices is one, the first data includes a plurality of sets of operating parameters of this reference device. When the number of reference devices is plural, the first data includes plural sets of operating parameters of each of the reference devices. Each set of operating parameters may include a plurality of different parameters, for example, each set of operating parameters may include an operating mode, an operating voltage, an operating temperature, and an operating humidity of the device during historical operation of the reference device.
And 102, acquiring a group of working parameters of the equipment to be tested at the current running time to obtain second data.
The second data are used for representing the technical performance of the equipment to be tested; the equipment model of the equipment to be tested is the same as that of the reference equipment. The equipment technical performance of the equipment to be tested comprises one or more of operation parameters of the equipment to be tested, structural characteristics of the equipment to be tested, technical specifications of the equipment to be tested and precision grade of the equipment to be tested. The operating parameters of the device under test may include a set of operating parameters for the current operating time of the device under test. The set of operating parameters may be the same as the parameters included in each set of operating parameters of the reference device. For example, the set of operating parameters includes an operating mode, an operating voltage, an operating temperature, and an operating humidity of the device at the current operating time of the device under test.
Of course, in the embodiment of the present invention, the types of parameters included in each of the sets of operating parameters of the reference device and the set of operating parameters of the device under test are not specifically limited. It should be noted that each group of operating parameters in the multiple groups of operating parameters of the reference device and a group of operating parameters of the device under test both obey the same rule and distribution under the same operating environment.
In the embodiment of the invention, the information acquisition device can acquire the working parameters of each period in the historical operation of at least one reference device in a first period; the information acquisition device may acquire a set of working parameters of the current operating time of the device to be tested in a second time period, where the time length of the second time period is the same as that of the first time period, the service time period of the device to be tested corresponding to the second time period may be the same as that of the reference device corresponding to the first time period, and the service time period of the device to be tested corresponding to the second time period may be different from that of the reference device corresponding to the first time period.
For example, after acquiring the historical operating parameters of the reference device, the information acquisition device may analyze the historical operating parameters to determine that the device to be tested has been used for 5 months. Further, if the information acquisition device determines that the curve fitting degree of a first curve corresponding to month 1 to month 5 in the historical operation parameters of the reference device and a second curve corresponding to the historical operation parameters of month 5 of the device to be tested meets a preset condition, the information acquisition device may set the first time period as a time period corresponding to month 5 in the service process of the reference device, and set the second time period as a time period corresponding to month 5 of the device to be tested, and then, the information acquisition device sets each cycle, such as each day, according to the working frequency of the reference device, so that the information acquisition device may extract the working parameters of each day based on the historical operation parameters of month 5 in the service process of the reference device, obtain 31 sets of working data, and determine the 31 sets of working data as the first data; and extracting the 31 th day working parameters based on the 5 th month historical operating parameters in the service process of the equipment to be tested to obtain 1 group of working data and determine the group of working data as second data. If the information acquisition equipment judges that the reference equipment hardly runs in the 1 st to 5 th months in the historical operation parameters and the curve fitting degree of a third curve corresponding to the 5 th to 10 th months and a second curve corresponding to the 5 th month historical operation parameters of the equipment to be detected meets the preset conditions, the information acquisition equipment can set a first time period as a time period corresponding to the 10 th month in the service process of the reference equipment and set a second time period as a time period corresponding to the 5 th month of the equipment to be detected, and then the information acquisition equipment sets each period as each day according to the working frequency of the reference equipment, so that the information acquisition equipment can extract the working parameters of each day based on the 10 th month historical operation parameters in the service process of the reference equipment, obtain 31 groups of working data and determine the 31 groups of working data as the first data; and extracting the 31 th day working parameters based on the 5 th month historical operating parameters in the service process of the equipment to be tested to obtain 1 group of working data and determine the group of working data as second data.
In the embodiment of the invention, the information acquisition equipment can flexibly set the first time interval and each period based on the use frequency of the reference equipment so as to ensure that the acquired working parameters in the historical operation of the reference equipment have a larger coverage range and a higher reference value, thereby improving the information acquisition accuracy of the information acquisition equipment.
And 103, calculating the matching degree of a group of working parameters in the second data and each group of working parameters in the first data.
Here, the degree of matching between a set of operating parameters in the second data and each set of operating parameters in the first data is calculated, that is, the degree of similarity between a set of operating parameters in the second data and each set of operating parameters in the first data is calculated.
The information acquisition device may calculate the degree of similarity between a group of operating parameters in the second data and each group of operating parameters in the first data using a distance function, and the commonly used distance function may be an euclidean distance function, a variance weighted distance function, a chebyshev distance function, or the like. Preferably, in the embodiment of the present invention, a euclidean distance function may be used to calculate the similarity between a set of operating parameters in the second data and each set of operating parameters in the first data.
And step 104, determining the residual service life of the equipment to be tested according to the matching degree and the reference residual service life.
After the information acquisition device calculates the matching degree of a group of working parameters in the second data and each group of working parameters in the first data, the information acquisition device can determine the remaining service life of the device to be tested according to the matching degree and the reference remaining service life.
In the embodiment of the present invention, no matter the number of the reference devices is one or more, if the information obtaining device can select one maximum matching degree from the calculated matching degrees, the information obtaining device may determine a group of working parameters in the third data corresponding to the maximum matching degree to obtain the target working parameters, and determine the reference remaining service life corresponding to the target working parameters as the remaining service life of the device to be measured.
According to the information acquisition method provided by the embodiment of the invention, the working parameters of each period in the historical operation of at least one reference device are acquired to obtain first data, and the reference remaining service life corresponding to the first data is acquired; wherein the first data is used to characterize a device technology capability of the at least one reference device; the first data includes a plurality of sets of operating parameters; acquiring a group of working parameters of the equipment to be tested at the current running time to obtain second data; the second data are used for representing the technical performance of the equipment to be tested; the equipment model of the equipment to be tested is the same as that of the reference equipment; calculating the matching degree of a group of working parameters in the second data and each group of working parameters in the first data; determining the residual service life of the equipment to be tested according to the matching degree and the reference residual service life; that is to say, in the embodiment of the present invention, the working parameters of the reference device in multiple time periods are matched with the working parameters of the device to be measured in the current time period, and the remaining service life of the device to be measured is intelligently predicted according to the matching result and the reference remaining service life corresponding to the working parameters of the reference device, so that the problems that the prediction accuracy is low and the true remaining service life of the device cannot be predicted by a manual prediction method in the prior art are solved, and the accuracy of predicting the remaining service life of the device is improved.
Based on the foregoing embodiments, an embodiment of the present invention provides an information obtaining method, which is applied to information obtaining devices, where in the embodiment of the present invention, the number of reference devices is one, and as shown in fig. 2, the method includes the following steps:
step 201, obtaining a working parameter of each period in historical operation of a reference device to obtain first data, and obtaining a reference remaining service life corresponding to the first data.
Wherein the first data is used to characterize a device technology capability of the at least one reference device; the first data includes a plurality of sets of operating parameters.
Step 202, obtaining a group of working parameters of the equipment to be tested at the current running time to obtain second data.
The second data are used for representing the technical performance of the equipment to be tested; the equipment model of the equipment to be tested is the same as that of the reference equipment.
Step 203, screening the working parameters of which the correlation coefficient with the reference remaining service life is greater than a preset threshold value from each group of working parameters of the first data to obtain third data, and screening the working parameters of which the types are the same as those of the parameters included in the third data from the second data to obtain fourth data.
Here, after the information obtaining device obtains the first data including a plurality of sets of operating parameters from the operating parameters of each period in the historical operation of the reference device, the information obtaining device may calculate correlation coefficients between the plurality of parameters included in each set of operating parameters and the reference remaining service life, and if the correlation coefficients are greater than a preset threshold, the information obtaining device may screen the operating parameters whose correlation coefficients with the reference remaining service life are greater than the preset threshold from each set of operating parameters of the first data to obtain the third data.
For example, the reference device may be an electric cooker, and each set of operating parameters in the first data of the electric cooker may include the following parameters: temperature, humidity, scented rice, instant rice, and no pot failure. The information acquisition device calculates the correlation coefficients between the temperature, the humidity, the aromatic rice, the fast rice, and the no-pot fault and the reference remaining service life, respectively, and can obtain a correlation coefficient corresponding to the temperature of 0.815, a correlation coefficient corresponding to the humidity of 0.823, a correlation coefficient corresponding to the aromatic rice of 0.794, a correlation coefficient corresponding to the fast rice of 0.802, and a correlation coefficient corresponding to the no-pot fault of 0.912. If the preset threshold is 0.8, the information acquisition device screens temperature, humidity, fast rice and no-pot faults from each group of working parameters of the first data in the first working parameters according to the condition that the correlation coefficient is greater than the preset threshold, and obtains third data. Then, the information obtaining device filters the working parameters with the same type as the parameters included in the third data from the second data to obtain fourth data, that is, the fourth data also includes: temperature, humidity, fast meals, and no pot failure.
And 204, calculating the matching degree of the working parameters in the fourth data and each group of working parameters in the third data to obtain the matching degree of a group of working parameters in the second data and each group of working parameters in the first data.
Here, it is assumed that the third data extracted by the information acquisition apparatus includes 5 sets of operating parameters, and euclidean distances, i.e., matching degrees, between the operating parameters in the fourth data and each set of operating parameters in the third data are calculated as P1, P2, P3, P4, and P5, respectively, and P1 < P2 < P3 < P4 < P5.
And step 205, acquiring a group of working parameters in the third data corresponding to the maximum matching degree in the matching degrees to obtain target working parameters.
Here, the information acquiring apparatus determines that the maximum matching degree among P1, P2, P3, P4, and P5 is P5, and acquires a set of operating parameters in the third data corresponding to P5 to obtain target operating parameters.
And step 206, acquiring the reference remaining service life corresponding to the target working parameter, and determining the reference remaining service life corresponding to the target working parameter as the remaining service life of the device to be tested.
Here, the information acquiring apparatus acquires a set of operating parameters in the third data corresponding to P5, acquires a reference remaining service life corresponding to the target operating parameter, for example, 5 years after obtaining the target operating parameter, and then the information acquiring apparatus determines that the remaining service life of the device under test is 5 years.
And step 207, generating and outputting prompt information for prompting the remaining service life of the equipment to be tested.
The information acquisition equipment generates prompt information for prompting the remaining service life of the equipment to be tested and outputs the prompt information in a voice mode or a voice plus display mode so as to remind a user to make a decision in advance according to the remaining service life of the equipment to be tested, thereby reducing shutdown loss and ensuring the use stability of the equipment.
It should be noted that, for the descriptions of the same steps and the same contents in this embodiment as those in other embodiments, reference may be made to the descriptions in other embodiments, which are not described herein again.
