Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:

[0051] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0052] Embodiment 1:

[0053] The embodiment of the present invention provides a deviation correction and positioning system, such as Figure 1 As shown, including:

[0054] Data acquisition module: obtains the current positioning information of the device to be located and performs overall analysis on the current positioning information;

[0055] Area determination module: determines the primary correction area according to the overall analysis result, performs correlation analysis on the primary correction area, and determines the secondary correction area;

[0056] A correction processing module: determines a primary offset value of the primary correction area, and performs correction simulation on the secondary correction area to determine a secondary offset value, so as to correct the actual positioning value according to the primary offset value and the secondary offset value;

[0057] Positioning module: perform positioning analysis on all deviation correction areas, determine the deviation-prone areas based on the correction results and positioning analysis results, set solutions for the deviation-prone areas, adjust the current positioning information of the device to be positioned, and obtain deviation correction instructions for the deviation correction control of the device to be positioned.

[0058] In this embodiment, the current positioning information includes the physical location, status information and environment information of the coating machine and the lithium battery produced on the coating machine.

[0059] In this embodiment, the overall analysis process is to analyze the current positioning information, such as statistically analyzing the positioning coordinates, observing the distribution of positioning errors, and analyzing the correlation between positioning errors and factors such as time and device status.

[0060] In this embodiment, the association analysis is to determine the first-level correction area based on the comparison result of the original operating state and the current operating state of the device to be positioned, determine the possible affected area of ​​the first-level correction area, and positionally number the first-level correction area and the possible affected area, and determine the second-level correction area by combining the support determined by the impact distribution of the first-level correction area with the position number.

[0061] In this embodiment, the correction simulation sets a simulation environment based on the first-level correction value. The simulation environment includes the device status, the surrounding environment, and possible interference sources. The model is applied in the set environment to simulate the correction simulation of the device to be positioned and the possible changes in its positioning value. By comparing the simulation results with the state before correction, the second-level offset value is obtained.

[0062] In this embodiment, the first-level correction area is generally determined based on the overall analysis results of the current positioning information. For example, in a coating machine production workshop, the first-level correction area covers a macro area in the workshop, such as a corner of the workshop. Because it is far from the wireless signal transmission point, the positioning information of all coating machines working in this area may have some deviations. At this time, the first-level offset value of the first-level correction area may be derived from the average positioning deviation in this corner area, which is used to make a preliminary correction to the positioning information in this macro area.

[0063] In this embodiment, the secondary correction area is defined based on the influence distribution of the primary correction area. For example, in a storage area in the corner of a workshop, the wireless signal is severely attenuated due to the obstruction of a large number of metal objects, making the positioning deviation of the coating machine in the storage area greater than the average value of the primary correction area.

[0064] In this embodiment, the correction model corresponding to the correction simulation collects the positioning data of the coater in the production line to determine the first-level correction area, such as the starting area, middle area and terminal area of ​​the production line; according to the positioning information of the coater in these areas and its original positioning information in the air transport state, the first-level correction value of each first-level correction area is determined; according to all the first-level correction areas and their corresponding first-level correction values, a primary model is constructed, which is a mapping relationship between different positioning correction values ​​of the coater in different areas; factors affecting the positioning accuracy, such as environmental noise, equipment aging, etc., are obtained, and the primary model is optimized to obtain a correction model.

[0065] In this embodiment, the correction simulation is performed on the secondary correction area under the primary correction area. For example, we find that the positioning error of the coating machine is larger at a certain position (secondary correction area) in the middle area (primary correction area) of the production line. The correction model is used to perform simulation calculations to determine the secondary correction value of this specific position.

[0066] In this embodiment, the positioning analysis is a systematic positioning data analysis of all correction areas to understand and locate the laws or patterns of the occurrence of deviations, which usually includes data collection, data processing, analysis of positioning errors and analysis of influencing factors, and finally interpretation of the positioning results.

[0067] In this embodiment, the set solutions include hardware upgrade, software optimization, environment adjustment and path planning. For example, it is assumed that during the operation of the coater, the coater is more likely to have positioning deviation in the starting area and middle area of ​​the production line (that is, the first-level correction area), especially the coating machine at a specific position of the production line (that is, the second-level correction area) has a larger positioning error; after positioning analysis and correction, it is determined that these deviation-prone areas are caused by electromagnetic interference caused by a large number of metal equipment in the factory. In response to this situation, the following solutions can be set: upgrade the hardware of the coater and use more advanced electromagnetic shielding technology to make it less susceptible to electromagnetic interference when working; on the working route of the coater, try to avoid these high electromagnetic interference areas and change the movement path of the equipment; optimize the environment around the production line, such as adjusting the position of large metal equipment to reduce its interference with the positioning of the coater.

[0068] The working principle and beneficial effects of the above technical solution are: the first-level correction area and the second-level correction area are determined after an overall analysis of the current positioning information of the device to be positioned, thereby determining the first-level correction value and the second-level correction value, and the actual positioning value is modified by the offset value of the first-level correction area and the second-level correction area, and the offset-prone area is determined, and the corresponding correction instructions are generated, thereby realizing real-time adjustment and control, improving positioning accuracy, discovering and solving offset problems, and improving work efficiency.

[0069] Embodiment 2:

[0070] The embodiment of the present invention provides a deviation correction and positioning system, a data acquisition module, including:

[0071] An analysis unit: analyzing the current positioning information and multiple groups of historical positioning information of the device to be positioned, to determine the hidden rules and potential problems of the device to be positioned;

[0072] Result unit: determine the operation-friendly situation of the hidden rules and potential problems;

[0073] The overall analysis result is formed based on the hidden rules and potential problems and combined with the operation-friendly situation.

[0074] In this embodiment, the analysis of positioning information is to extract and process the current positioning information and the historical positioning information, including data cleaning, data preprocessing, and extraction of analysis features. The analysis features include positioning accuracy, positioning frequency, and positioning deviation. The hidden rules and potential models are determined by inputting the analysis features into the regression model.

[0075] In this embodiment, the hidden laws include time laws, i.e., systematic deviations of the positioning system occur in a specific time period; geographical laws, i.e., positioning deviations occur in specific geographical locations or terrains; and environmental laws, i.e., laws that affect positioning accuracy in a specific environment.

[0076] In this embodiment, potential problems include calibration issues, signal interference, device performance, or software issues.

[0077] In this embodiment, the operation-friendly conditions include system performance, system stability, power consumption, and resource usage.

[0078] The working principle and beneficial effect of the above technical solution are: by analyzing the current positioning information, the overall analysis situation of the device to be positioned is determined, valuable information is provided, and continuous improvement of device performance is achieved.

[0079] Embodiment 3:

[0080] The embodiment of the present invention provides a deviation correction and positioning system, an area determination module, including:

[0081] The primary area determination unit: performs a first comparison between the original operating states of different devices to be located in the same time period and the corresponding current operating states, and at the same time, performs a second comparison between the original operating states of the same device to be located in different time periods and the corresponding current operating states;

[0082] Determine an initial deviation correction area of ​​the device to be positioned according to the second comparison result, and adjust the initial deviation correction area according to the basic offset area determined by the first comparison result to obtain all primary deviation correction areas of the device to be positioned;

[0083] Possible area determination unit: according to the regional connection of all the first-level deviation correction areas under the device to be positioned, setting the possible impact area corresponding to each first-level deviation correction area;

[0084] A connection and number determination unit: based on the connection between each primary correction area and all corresponding possible affected areas under the device to be positioned, at the same time, each primary correction area is assigned a first position number and all possible affected areas corresponding to each primary correction area are assigned a second position number;

[0085] Secondary area determination unit: based on the area connection situation and the position number result, all possible impact areas corresponding to each primary deviation correction area under the device to be positioned are screened to determine the corresponding secondary deviation correction area.

[0086] In this embodiment, the first comparison is to compare the operating conditions of different devices in the same time period to determine whether the performance of different devices is consistent under the same conditions, and whether there are problems with the devices themselves. For example, if the positioning data of all devices at the same time and place should be very close, if the positioning data of a certain device is obviously inconsistent with that of other devices, then there may be a problem.

[0087] In this embodiment, the second comparison is to compare the operating status of the same device in different time periods to determine whether the performance of the device changes over time, whether there are periodic problems, or whether the device can operate stably for a long time. For example, in the second case, if the positioning data of a device in a certain time period is significantly different from its positioning data in other time periods, then the device may have a positioning problem in certain specific time periods and further verification is required.

[0088] In this embodiment, the second comparison result is based on the comparison of the operating status of the same device in different time periods, from which possible positioning problems of the device can be discovered, such as positioning offset in a specific time period, and a preliminary correction area is determined based on this, that is, a specific area where the device may have a position offset.

[0089] In this embodiment, the first comparison result is based on the comparison of the operating status of different devices in the same time period to determine that if multiple devices are under the same conditions, their performance should be consistent. If a device displays different data, it may be that the device has an offset problem, and the basic offset area is determined accordingly.

[0090] In this embodiment, the initial correction area is determined based on the comparison results of the operating status of the device in different time periods. For example, the positioning ability of the device in a specific time period (such as at night) is weaker than that during the day, or the positioning ability of the device decreases when the battery is low. This comparison of states can establish error tendencies or patterns that may occur under specific conditions.

[0091] In this embodiment, the basic offset area is determined based on the comparison results of the operating states of different devices to be located in the same time period. For example, if at a specific time and place, the positioning data of all devices should be very close, if the positioning data of a certain device is obviously inconsistent, it may indicate that the device has a positioning offset.

[0092] In this embodiment, the connection situation refers to the geographical or spatial relationship between the first-level correction area and its corresponding possible impact area, that is, how the two areas are connected in location. For example, the possible impact area may be next to the first-level correction area, or surround the first-level correction area, or be a certain distance away from the first-level correction area.

[0093] The working principle and beneficial effects of the above technical solution are: determining the first-level correction area by comparing the original operating state with the current operating state, expanding the possible affected area of ​​the first-level correction area, and numbering the first-level correction area and the possible affected area, determining the second-level correction area, refining the positioning accuracy, and improving the overall positioning effect.

[0094] Embodiment 4:

[0095] The embodiment of the present invention provides a deviation correction and positioning system, a secondary area determination unit, including:

[0096] A distribution determination subunit: determining, according to the first position number and the second position number, an influence distribution of the corresponding first-level correction area, wherein the influence distribution includes a first area unrelated to the remaining first-level correction area and the position of the first area, and a second area related to the remaining first-level correction area and the position of the second area;

[0097] A calculation subunit: according to the influence distribution, respectively calculates the support degree of each first-level correction area;

[0098]

[0099]

[0100]

[0101] in, Indicates the correlation coefficient between the primary correction area X and the corresponding first area involved; Indicates the correlation coefficient between the primary correction area X and the corresponding second area; represents the area of ​​the corresponding i1th first region involved; represents the position weight of the i1th first region involved; represents the area of ​​the corresponding i2-th second region involved; represents the position weight of the i2th second region involved; Indicates the location information of the corresponding first area determined based on the area connection situation A connection coefficient with the position information w0 corresponding to the first correction area; Indicates the location information of the corresponding second area determined based on the area connection situation A connection coefficient with the position information w0 corresponding to the first correction area; represents the overlapping area of ​​the corresponding i2-th second area and the corresponding primary correction area; Indicates the area of ​​the corresponding first-level correction area; , represents the calculation factor;

[0102] According to the support, the random frame selection ratio of the corresponding first-level correction area is determined to proportionally screen all possible affected areas involved in the corresponding first-level correction area to obtain the corresponding second-level correction area.

[0103] In this embodiment, the random selection ratio is used to further screen and reduce the number of possible affected areas. According to the support, the system will generate a random selection ratio, and then randomly select the possible affected areas according to this ratio. Areas outside this ratio range may be considered unlikely to be affected, and thus be eliminated in the determination of the secondary correction area. For example, if the support of a certain level of correction area is very high, then the corresponding random selection ratio may be relatively large, and the possible affected area will have a greater probability of being selected and included in the secondary correction area. Conversely, if the support is low, then the random selection ratio may be relatively small, thereby excluding more areas during screening.

[0104] The working principle and beneficial effects of the above technical solution are: through the first position number of the first-level correction area and the second position number of the possible affected area, the corresponding impact distribution is determined, the support degree of each first-level correction area is calculated, and the second-level correction area is determined according to the support degree, so as to more accurately determine the area that needs to be corrected and improve the positioning accuracy.

[0105] Embodiment 5:

[0106] The embodiment of the present invention provides a deviation correction and positioning system, a deviation correction processing module, including:

[0107] A first-level deviation correction value determination unit: determines the first-level deviation correction value of each first-level deviation correction area according to the current positioning information and the original positioning information of the original operating state;

[0108] Model building unit: builds a primary model based on all primary correction areas and corresponding primary correction values, and obtains factors affecting positioning accuracy;

[0109] Optimizing the primary model according to the accuracy factor to obtain a correction model;

[0110] A secondary correction value determination unit: performs correction simulation on the secondary correction area under each primary correction area based on the correction model, and determines the secondary correction value corresponding to the secondary correction area;

[0111] Correction unit: Corrects the actual positioning value by combining the primary offset value and the secondary offset value.

[0112] In this embodiment, the original positioning information refers to the status and location information of the device when it leaves the manufacturer's factory, or the device after initial setting or last maintenance.

[0113] In this embodiment, the model is established to find out the relationship between the first-level correction value, the second-level correction value, and the factors affecting the positioning accuracy, and to mathematize them to form a model that can accurately predict and correct positioning errors. The model dynamically calculates the first-level correction value and the second-level correction value based on the specific conditions of each area and the factors affecting the positioning accuracy, and uses them to correct the actual positioning value of the equipment.

[0114] The working principle and beneficial effects of the above technical solution are: the first-level correction value is determined by the current positioning information and the original positioning information, and a correction model is constructed therefrom. The correction simulation is performed on the second-level correction area to determine the second-level correction value. The actual positioning value is corrected based on the combination of the first-level correction value and the second-level correction value, thereby achieving accurate positioning and correction of the equipment to be positioned, improving production accuracy and efficiency, and is conducive to improving product quality and production safety.

[0115] Embodiment 6:

[0116] An embodiment of the present invention provides a deviation correction positioning system, wherein the accuracy factor is related to the current spatial environment in which the device to be positioned is located, the device loss characteristics, and the signal attenuation of the current positioning information during the transmission process.

[0117] In this embodiment, the current spatial environment of the device to be positioned includes factors such as the physical environment of the device (such as indoors or outdoors, height, temperature, etc.), whether there are shielding or interference around (such as buildings, trees, etc.), whether there are other electromagnetic sources, etc. Different spatial environments will have different effects on positioning accuracy.

[0118] In this embodiment, the device wear characteristic refers to the performance degradation or damage that may occur to the device during use. For example, the depletion of battery power may cause the positioning function of the device to decline, or the device may be used for too long, resulting in the decline of some hardware functions.

[0119] In this embodiment, the signal attenuation of the current positioning information during the transmission process may be caused by factors such as distance, obstacles, and weather during the process of sending the positioning information from the device to the receiving end, thereby affecting the accuracy of the positioning information.

[0120] The working principle and beneficial effects of the above technical solution are: to refine the accuracy factors, determine the accuracy of each device to be positioned based on the correction model, and achieve more accurate correction of positioning errors.

[0121] Embodiment 7:

[0122] The embodiment of the present invention provides a deviation correction and positioning system, a positioning module, including:

[0123] Cause determination unit: perform positioning analysis on all correction areas, merge all primary correction areas and secondary correction areas according to the positioning analysis results, and determine the corrected correction area;

[0124] Obtaining the regional attributes of the correction and deflection correction area, and determining the cause of the deviation of the correction and deflection correction area;

[0125] An information acquisition unit: based on the correction result of the secondary correction area and the regional relationship between the second correction area and the correction correction area, adjusting the correction result to obtain the final correction information of the correction correction area;

[0126] Optimization unit: Determine the areas where deviations are frequent based on the last correction information and the positioning analysis results, formulate solutions based on the regional locations of the areas where deviations are frequent and the equipment characteristics of the device to be positioned, adjust the current positioning information of the areas where deviations are frequent, obtain deviation correction instructions and perform deviation correction control on the device to be positioned.

[0127] In this embodiment, the merging of correction areas includes merging in space. If the primary correction area and the secondary correction area overlap or are adjacent in space, then they can be merged into a large correction area, thereby reducing the complexity of subsequent processing; in the merging in positioning correction, if the primary correction area and the secondary correction area have a certain correlation in the positioning correction value, then they can also be merged into a large correction area and corrected together.

[0128] In this embodiment, obtaining the region attributes of the correction and deflection correction region may involve collecting detailed information about the region, such as the location, size, shape, and possible environmental factors of the region.

[0129] In this embodiment, the regional relationship is a relationship in spatial position, and they may be intersecting, containing, adjacent or separated, etc. For example, a secondary correction area may be located inside a correction correction area, or may partially overlap with the correction correction area, or may be near the correction correction area or have a certain distance between them.

[0130] In this embodiment, the adjustment method is set according to the cause of the error. For example, if it is found that the error is mainly caused by equipment performance problems, it may be necessary to appropriately adjust equipment parameters or replace the equipment; if it is found that the error is mainly caused by environmental factors, it may be necessary to adjust the environmental conditions, such as selecting a better positioning time point or improving the position of the receiver.

[0131] The working principle and beneficial effects of the above technical solution are: by analyzing all the correction areas, determining the causes of the deviation in the correction areas, and based on the determined causes of the deviation, analyzing the correction results and the relationship between the correction areas to obtain the final correction information, determining the areas where deviations are frequent, and then formulating solutions based on the characteristics of the equipment, and adjusting the areas where deviations are frequent, a method is implemented that makes full use of various types of information to accurately correct and optimize positioning deviations, which helps to improve the performance and stability of the positioning system.
