It should also be understood that the term "and/or" as used in this disclosure is intended to encompass any or all possible combinations of one or more of the listed items.
The terms "first," "second," and the like, are used below for descriptive purposes only and are not to be construed as implying or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature, and in the description of embodiments of the application, unless otherwise indicated, the meaning of "a plurality" is two or more.
Referring to fig. 1, an architecture diagram of a data replication system according to an embodiment of the present application is shown.
The data replication system 1 includes a transmitting device 10 and a receiving device 12. The transmitting device 10 and the receiving device 12 are two independent devices. In the embodiment of the present application, the sending device 10 and the receiving device 12 are digital display pressure sensors, which are respectively used for sending and receiving data to be copied, so as to realize data copying. In addition, both the transmitting device 10 and the receiving device 12 adopt microprocessor technology, so that the operation control of the transmitting device and the receiving device is more intelligent. Not only can automatic measurement and recording be completed, but also the accuracy and stability of data can be improved through digital signal transmission. And the sending device 10 and the receiving device 12 are also provided with touch screens and data processing functions, so that data can be monitored and processed and analyzed in real time, and the working efficiency and the requirements of clients are met.
In the embodiment of the present application, the data to be copied is copied to the receiving apparatus 12 by the transmitting apparatus 10, so as to achieve that the data set value in the transmitting apparatus 10 is consistent with the data set value in the receiving apparatus 12. Referring to fig. 4 together, first, the transmitting device 10 detects whether or not its own first device model matches the second device model of the receiving device 12 within a first preset period of time (for example, 2 seconds), and when the first device model matches the second device model, determines which of the data to be copied in the transmitting device 10 needs to be copied to the receiving device 12, the transmitting device 10 copies the data to be copied to the receiving device 12. Further, when the receiving device 12 receives the data to be copied, it is checked whether the data to be copied is copied successfully within a second preset time period (for example, 10 seconds), and when the data to be copied is completely copied successfully, the receiving device 12 updates the data to be copied by using the data to be copied, and sends the copy information carrying the copy success to the sending device 10, so that the sending device 10 can know that the receiving device 12 has received all the information to be copied when receiving the copy information, and does not need to resend the information to be copied to the receiving device 12, thereby realizing that the set value of each data between the sending device 10 and the receiving device 12 is consistent, not needing to be manually involved, and realizing quick and accurate data copying.
Referring to fig. 2, a flowchart of a data replication method according to an embodiment of the present application is shown, and the data replication method includes the following steps.
S21, the sending device detects whether the first device model is matched with the second device model of the receiving device.
Digital-type pressure sensors of different device models may have different hardware architectures, storage formats, or communication protocols. If data is copied from one model of device to another model of device, data copy failure or data corruption may result from hardware compatibility issues. Secondly, copying the data to be copied of the transmitting device to the receiving device is to ensure that the set value of each data of the transmitting device and the receiving device are consistent, and when the model numbers between the transmitting device and the receiving device are not matched, the set value between the two devices cannot be completely consistent even if the data to be copied is successfully copied.
Therefore, before copying data to another device, the device models of the transmitting device and the receiving device need to be acquired, the device model of the transmitting device is referred to as a first device model, and the device model of the receiving device is referred to as a second device model. The receiving device further verifies whether the first device model matches the second device model for a first preset period of time (e.g., 2 seconds). When the first equipment model is matched with the second equipment model, the receiving equipment receives the data to be copied sent by the sending equipment.
In an alternative embodiment, the sending device detecting whether the first device model matches the second device model of the receiving device includes:
the sending equipment receives an input signal sent by the receiving equipment and detects whether a handshake signal in the input signal is read or not in a third preset time period;
and when the handshake signal is read in the second preset time period, the sending equipment returns a target signal corresponding to the handshake signal to the receiving equipment and executes an operation of detecting whether the first equipment model is matched with the second equipment model of the receiving equipment.
Referring also to fig. 5, before comparing the device models between the transmitting device and the receiving device, it is necessary to ensure that both the transmitting device and the receiving device enter the copy mode. In particular, the transmitting device receives an input signal from the receiving device, wherein the input signal may comprise a handshake signal. Further, the sending device detects whether the handshake signal sent by the receiving device is read or not within a third preset time period (for example, 5 seconds), the sending device starts to check whether a target signal is returned to the receiving device after the handshake signal is read, when the sending device is determined to read the handshake signal and returns a target signal to the receiving device after the handshake signal is read, the sending device and the receiving device are indicated to both enter a copy mode, and the sending device can execute the next step, namely, whether the first device model and the second device model are matched or not is detected. When it is determined that the transmitting device does not read the handshake signal, or after the handshake signal is read and in order to return a target signal to the receiving device, it may be determined that at least one of the transmitting device and the receiving device has not performed a copy mode, and no operation of detecting whether the first device model and the second device model of the receiving device match is performed.
In some embodiments, since the sending device and the receiving device are both dual-digital-display digital pressure sensors and have a dual-screen display function, when the device model between the sending device and the receiving device is consistent, or whether the data copying is successful, etc., the data can be displayed through the display. In addition, the current value and the reference value can be checked at the same time, and the reference value can be checked and set smoothly without switching the screen mode. When an operation of setting a reference value or the like is performed in the transmitting apparatus and the receiving apparatus perform a copy mode, the relevant data setting performed in the transmitting apparatus is synchronously copied to the receiving apparatus.
In an alternative embodiment, the method further comprises:
triggering a mechanical error signal when the sending device detects that the first device model is not matched with the second device model in the first preset time period;
and alarming according to the mechanical error signal, and displaying the comparison result of the first equipment model and the second equipment model.
Referring to fig. 5, when the first equipment model is not matched with the second equipment model in the first preset time period, the equipment triggering model error signal is sent, and an alarm is given according to the model error signal so as to remind relevant staff to find the mismatch problem between the equipment in time. In addition, the transmitting device may also transmit copy error data with a non-matching model to the receiving device, and display error reporting information with a non-matching model.
In other embodiments, the receiving device may also verify whether the first device model matches the second device model for a first preset time period (e.g., 2 seconds), and when the first device model does not match the second device model for the first preset time period, the receiving device triggers a model error signal. In addition, the sending device and the receiving device can display the first device model and the second device model, and the comparison result between the first device model and the second device model, for example, the comparison result can be that the first device model is matched with the second device model, or the first device model is not matched with the second device model, so that related staff can take related measures to solve the problem of model mismatch, follow-up data transmission is ensured to be carried out smoothly, and data consistency is maintained.
When the first device model matches the second device model within the first preset time period, the transmitting device transmits the data to be copied to the receiving device, and the receiving device receives the data to be copied and verifies whether the data to be copied is copied successfully, i.e. step S22 is performed.
And S22, when the sending equipment detects that the first equipment model is matched with the second equipment model in a first preset time period, the sending equipment copies the data to be copied to the receiving equipment, so that the receiving equipment checks whether the data to be copied is copied successfully in a second preset time period, and returns copy information.
In the embodiment of the present application, since the sending device and the receiving device are both digital display type pressure sensors, the data to be copied may include, but is not limited to: calibration parameters (e.g., zero calibration values, slope calibration values, etc.), configuration setting parameters (e.g., measurement range, sampling frequency, alarm threshold, etc.), etc. In some embodiments, the sending device may transmit the data to be replicated to the receiving device directly over a cable or network line according to wired communications (e.g., serial communications interface, ethernet interface, etc.); the transmitting device may also communicate with the receiving device through wireless communication (e.g., wi-Fi, bluetooth, zigbee, etc.), that is, through a wireless module built in the transmitting device or an external wireless adapter, and copy the data to be copied into the receiving device.
In an alternative embodiment, the transmitting device firstly acquires all data of itself, called a first data set, and simultaneously acquires all data in the receiving device, called a second data set, and compares the first data set with the second data set to determine whether the second original data in the second data set is different from each first original video data in the first data set, when the second original data is different from the first original data, the second original data which is different is called target original data, and the target original data is determined as data to be copied, namely, only the data which is different from the receiving device is copied from the transmitting device to the receiving device, and the same data does not need to be copied. The transmitting device further determines the data amount of the data to be copied and judges whether the data amount of the data to be copied is greater than 1. When the number of the data to be copied is 1, representing that only one data in the receiving device and the sending device is different, the different data to be copied is directly copied into the receiving device. In some embodiments, the sending device may transmit the data to be replicated to the receiving device using a network transmission protocol such that the set point of each data in the receiving device is consistent with the sending device.
And when the data quantity of the data to be copied is more than or equal to 2, determining the importance degree corresponding to each piece of data to be copied, and copying the data to be copied to the receiving equipment according to the importance degree. Specifically, a data matrix is generated according to the data to be copied, wherein the data matrix is a two-dimensional array, each row in the data matrix represents the data of each function corresponding to the same device, and each column represents the data of different devices under the same function. And further performing feature calculation on the data matrix to obtain a plurality of target feature values. Specifically, principal component analysis (PRINCIPAL COMPONENT ANALYSIS, PCA) may be used to map the data to be copied from the original high-dimensional feature space into the low-dimensional feature space, and retain the most important principal component in the original data to be copied, where the principal component is a linear combination of the original feature data to be copied, i.e., the target feature value. Then, inputting the target characteristic value into a data importance degree analysis model which is trained and completed in advance based on a machine learning algorithm (such as K nearest neighbor algorithm (K Nearest Neighbors, KNN), decision tree, support vector machine (Support Vector Machine, SVM) and the like), outputting importance degree scores of each piece of data to be copied, finally sorting according to the importance degree scores, and copying the data to be copied to receiving equipment one by one according to the sorted result.
In other embodiments, when determining the target feature value corresponding to each piece of data to be replicated, the sending device may further sort the feature values corresponding to each piece of data to be replicated obtained through calculation from large to small. The eigenvalues represent the importance of the features of the data matrix, and the eigenvalues indicate the strength of the linear relationship that exists for each item of data in the data to be replicated. Larger eigenvalues represent a stronger linear relationship. By performing feature computation on the data matrix, it is thus possible to determine the most important feature in the data to be copied, i.e. the feature with the largest feature value. And further determining a cumulative contribution corresponding to each piece of data to be copied according to the sorted plurality of eigenvalues, wherein the cumulative contribution= (sum of the first n eigenvalues)/(sum of all eigenvalues). In some embodiments, a plurality of contribution threshold intervals may be preset, where each contribution threshold interval corresponds to a level of importance. For example, a first contribution degree threshold interval, a second contribution degree threshold interval and a third contribution degree threshold interval may be preset, where the first contribution degree threshold interval corresponds to the importance degree of the first level, the second contribution degree threshold interval corresponds to the importance degree of the second level, and the third contribution degree threshold interval corresponds to the importance degree of the third level, so that the importance degree corresponding to each piece of data to be replicated may be determined according to the accumulated contribution degree.
In some embodiments, before generating the data matrix, the data matrix may be generated according to the normalized data by calculating the mean and variance of each item of data in the data matrix, and normalizing the data of the corresponding item according to the mean and variance. By calculating the mean and variance of each item of data, quantitative indexes of the central tendency and the discrete degree of each feature in the data to be copied can be obtained. The normalization can enable the mean value and the variance among different features to be compared under the same scale, and the influence of the scale is eliminated.
After the transmitting device copies the data to be copied to the receiving device, the receiving device needs to verify whether the data to be copied is copied successfully within a second preset time period (for example, 10 seconds). And after the receiving device detects that the data to be copied are completely copied in the second preset time period, returning copy information carrying the copy success to the sending device so that the sending device executes step S23.
S23, the transmitting device receives the copy information.
After the sending device receives the copy information carrying the copy success sent by the device to be received, the sending device can know that the data to be copied is completely copied to the receiving device successfully, and the data to be copied which is not copied successfully can be not retransmitted later.
Referring to fig. 3, a flowchart of another data replication method according to an embodiment of the present application is shown. The data replication method may include the following steps.
S31, receiving data to be copied by a receiving device, wherein the data to be copied is the copy data which is sent by a sending device when detecting that a first device signal is matched with a second device signal of the receiving device in a first preset time period.
When the first equipment model of the sending equipment is matched with the second equipment model of the receiving equipment, the sending equipment sends the data to be copied to the receiving equipment, and the receiving equipment receives the data to be copied sent by the sending equipment.
S32, the receiving equipment checks whether the data to be copied is copied successfully in a second preset time period.
When the receiving device receives the data to be copied, it needs to be verified in a second preset time period (for example, 10 seconds) whether the data to be copied is successfully copied, which may include whether the data to be copied is completely copied, whether the data to be copied is erroneously copied, and the like.
In an optional embodiment, the receiving device verifying whether the data to be copied is copied successfully in a second preset time period includes:
Checking whether all the data to be copied are successfully copied to the receiving equipment or not, and checking whether target copy data with copy errors exist in the data to be copied or not;
when all the data to be copied are successfully copied to the receiving equipment and the target copy data does not exist in the data to be copied, determining that the data to be copied is successfully copied in the second preset time period;
And when the data to be copied is not completely copied to the receiving equipment successfully, and/or the target copy data exists in the data to be copied, determining that the data to be copied is not copied successfully in the second preset time period.
In the embodiment of the application, whether the data to be copied is copied successfully or not needs to be checked, whether the data to be copied is completely copied to the receiving equipment or not is also checked, and whether the data to be copied to the receiving equipment is completely copied correctly or not is also checked. Only when the data to be copied is completely copied to the receiving device and the data to be copied is completely copied correctly, it can be determined that the data to be copied is copied successfully within the second preset time period. If the data to be copied is not completely copied to the receiving device and/or the data to be copied is not completely copied correctly, it can be determined that the data to be copied is not copied successfully within the second preset time period.
And S33, if the data to be copied is copied successfully in the second preset time period, automatically updating the data according to the data to be copied, and returning copy information to the sending equipment.
When it is determined that the data to be copied is all successfully copied to the receiving apparatus, the receiving apparatus returns a copy success signal to the transmitting apparatus, and the receiving apparatus replaces the data to be copied by itself so as to be identical to the set value of each data in the transmitting apparatus. For example, the measurement range of the sending device is 0-20, the measurement range of the receiving device is 0-10, the measurement range of the sending device is copied to the receiving device on the assumption that the data to be copied is the measurement range, and when the copying is successful, the receiving device updates its measurement range according to the measurement range of the sending device, i.e. copies 0-20 to 0-10, so as to replace 0-10 with 0-20.
After the receiving device automatically updates the data according to the data to be copied, the copying information carrying the copying success signal is returned to the sending device, so that the sending device can not send the data to be copied which is not copied successfully to the receiving device.
Referring to fig. 5 together, when it is verified that the data to be copied is not copied successfully within the second preset time period, the receiving device may send a verification inaccuracy signal to the sending device, so that the sending device retransmits the data to be copied, which is not copied successfully, to the receiving device.
In an alternative embodiment, when the data to be copied is not copied successfully within the second preset time period, the method further includes:
Step 1, the receiving equipment returns the copying information carrying the copying unsuccessful signal to the sending equipment, and the sending equipment copies the target data to be copied corresponding to the copying unsuccessful signal to the receiving equipment;
Step 2, checking whether the target data to be copied is copied successfully in the second preset time period;
And step 3, when the target data to be copied is not copied successfully in the second preset time period, iteratively executing the steps 1 to 2 until the target data to be copied is copied successfully to the receiving equipment.
In some embodiments, first, the receiving device needs to determine which data in the data to be replicated is not replicated successfully, call the data to be replicated that is not replicated successfully as target data to be replicated, and return the replication information carrying the replication unsuccessful signal of the target data to be replicated to the sending device, so that the sending device can re-replicate the target data to be replicated to the receiving device, and the receiving device continues to check whether the re-replicated target data to be replicated is replicated successfully. If the copying is not successful, the receiving device returns a copying unsuccessful signal to the sending device, so that the sending device re-copies the copying unsuccessful data to the receiving device until all the data to be copied in the sending device are successfully copied to the receiving device.
The application detects whether the sending device and the receiving device perform the copy mode, when the sending device reads the handshake signal sent by the receiving device in a preset time period, and returns a target signal to the receiving device after reading the handshake signal so as to inform the receiving device of performing the copy mode. And then comparing the first device signal of the sending device with the second device model of the receiving device to ensure that the models between the sending device and the receiving device are matched before data copying. When the transmitting device copies the data to be copied to the receiving device, the receiving device checks whether the data to be copied is copied successfully, and when the data to be copied is copied successfully, the receiving device updates the data to be copied by using the data to be copied, so that the data set value in the receiving device is consistent with the data set value in the transmitting device, no manual participation is needed in the whole process, and the data copy can be realized rapidly and accurately.
