[0048] 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.

[0049] The present invention provides an automatic positioning correction system, such as Figure 1 The structural diagram of the first embodiment shown includes a front-end device and a back-end server connected based on a communication device. The communication device includes any one or more of a 4G network communication module, a 5G network communication module, a Beidou short message communication module, and a wired communication module.

[0050] The front-end device includes a positioning device for obtaining the real-time location data of the front-end device. The positioning device can be implemented as any one of a Beidou positioning device and a GPS positioning device. The real-time location data includes longitude data and latitude data.

[0051] The backend server is connected to an input device, and the input device is used to input the geographical location information of the front-end device. The server obtains pre-input location data based on the geographical location information; the pre-input location data includes longitude data and latitude data.

[0052] The backend server includes a processing device, which compares the instant location data with the pre-input location data. When the instant location data and the pre-input location data are inconsistent, the instant location data replaces the pre-input location data. The processing device can automatically replace the pre-input location data with the instant location data, so that the real location of the front-end device can replace the pre-input erroneous pre-input location. It is convenient for users to check in the backend.

[0053] like Figure 2 As shown, this is a structural diagram of a second embodiment of the automatic positioning and correction system, wherein the background server is connected to a display, and when the instant position data and the pre-input position data are inconsistent, the display displays the inconsistent instant position data and the pre-input position data simultaneously.

[0054] The present invention also provides an automatic positioning correction method, such as Figure 3 The flowchart of the first embodiment shown includes the following steps:

[0055] S1, step of obtaining the real-time location: obtaining the real-time location data of the front-end device, wherein the real-time location data includes longitude data and latitude data.

[0056] S2, step of obtaining a pre-input location: inputting geographical location information of the front-end device, and obtaining pre-input location data based on the geographical location information, wherein the pre-input location data includes longitude data and latitude data.

[0057] S3, comparison and replacement step: compare the instant location data and the pre-input location data, and when the instant location data and the pre-input location data are inconsistent, replace the pre-input location data with the instant location data. Through the above steps, when the instant location data and the pre-input location data are inconsistent, it proves that the pre-input location may be wrong, and the instant location data can automatically replace the pre-input location data, so that the real location of the front-end device can replace the pre-input wrong pre-input location. It is convenient for users to check in the background.

[0058] In one embodiment, the step of comparing the instant location data with the pre-input location data and replacing the pre-input location data with the instant location data when the instant location data and the pre-input location data are inconsistent further comprises the following steps:

[0059] Get the real-time longitude data and real-time latitude data in the real-time location data. For example, the real-time longitude data and real-time latitude data can be 100 degrees east longitude, 60 degrees north latitude, 120 degrees east longitude, 70 degrees north latitude, etc.

[0060] The pre-input longitude data and the pre-input latitude data in the pre-input location data are obtained. For example, the pre-input longitude data and the pre-input latitude data can be 100 degrees east longitude, 60 degrees north latitude, 120 degrees east longitude, 70 degrees north latitude, etc.

[0061] If the difference between the real-time longitude data and the pre-input longitude data is greater than a first preset value, the real-time longitude data replaces the pre-input longitude data. The first preset value may be 2. For example, the real-time longitude data is 100 degrees east longitude, and the pre-input longitude data is 105 degrees east longitude. At this time, the difference between the real-time longitude data and the pre-input longitude data is 5, which is greater than 2. At this time, the pre-input longitude data is assumed to be an incorrect value. The real-time longitude data 100 degrees east longitude replaces the pre-input longitude data 105 degrees east longitude, and the final longitude data generated is 100 degrees east longitude.

[0062] If the difference between the real-time latitude data and the pre-input latitude data is greater than a second preset value, the real-time latitude data replaces the pre-input latitude data. The first preset value may be 2. For example, the real-time latitude data is 60 degrees north latitude, and the pre-input latitude data is 65 degrees north latitude. At this time, the difference between the real-time latitude data and the pre-input latitude data is 5, which is greater than 2. At this time, the pre-input latitude data is assumed to be an incorrect value. The real-time latitude data 60 degrees north latitude replaces the pre-input latitude data 65 degrees north latitude, and the final latitude data is generated as 60 degrees north latitude.

[0063] In one embodiment, the step of obtaining the pre-input longitude data and the pre-input latitude data in the pre-input location data further includes the following steps:

[0064] The pre-input location data includes location name information, such as the National Intellectual Property Administration, Haidian District Government, Haidian Bridge Intersection, and the first intersection of Nanlishi Road.

[0065] Based on the name information, the data in the database is traversed to search for the longitude data and latitude data corresponding to the name information, and the corresponding longitude data and latitude data are used as pre-input longitude data and pre-input latitude data. The database may be software such as Amap, Baidu Map, Google Map, etc.

[0066] like Figure 4 As shown, the embodiment of the present invention provides the step of traversing the data in the database based on the name information, searching for the longitude data and latitude data corresponding to the name information, further comprising analyzing and optimizing the name information by using a formula, and then traversing the data in the database again by using the formula to find the longitude data and latitude data corresponding to the name information, and then using the big data optimization method to correct the obtained longitude data and latitude data to finally obtain the corresponding corrected longitude data and latitude data, and the specific steps include:

[0067] Step A1, name optimization step: Analyze and optimize the name information using formula (1) to obtain the characteristic value of the name information

[0068]

[0069] Where N represents the characteristic value of the name information; X i represents the frequency of occurrence of the i-th word in the name information; v represents the total number of words in the name information; in the formula It means taking the average of the frequencies of all words in the name information, and then It means that the frequency of each word in the name information is compared with the average frequency, so as to reflect the difference between the more important words in the name information and the average, and then amplify it by squaring, then traverse all the words in the name information, sum them up, and then attribute these differences to each word, so divide it by v and integrate them together to get the formula It indicates that the uncertainty factor of the average frequency is corrected; and then added to the average frequency to finally obtain the characteristic value of the name information;

[0070] Step A2, similarity value calculation step: using formula (2) to obtain similarity values ​​between each information in the database and the name information according to the characteristic value of the name information and the name information traversing the data in the database;

[0071]

[0072] Among them, H a Indicates the similarity value between the name information and the a-th name information in the database; represents the frequency of the jth word in the ath name information in the database; M represents the total number of words in the ath name information in the database; W represents the total number of name information in the database; It means comparing the characteristic value of the name information with the characteristic value of the ath name information in the database, so as to obtain the direct difference between the two characteristic values, and then using the formula The characteristic values ​​of all name information in the database are traversed and compared, and then the sum is divided by W to obtain the average difference between the characteristic value of the name information and the characteristic value of the name information in the database, and then used These differences are corrected, and then the actual difference between the name information and the a-th name information in the database is added. Finally, a similarity value between the name information and the ath name information in the database is obtained;

[0073] Sort the similarity values ​​between the name information and the ath name information in the database from large to small, select the smallest value as the name information in the database that is most similar to the name information, and obtain the corresponding longitude data E and latitude data G according to the name information in the database;

[0074] Step A3, replacement step: using formula (3) to analyze the relationship between the difference between the longitude data obtained in step A2 and the pre-input longitude data and the first preset value, and the relationship between the difference between the latitude data obtained in step A2 and the pre-input latitude data and the second preset value, to obtain the replacement control value

[0075]

[0076] Where K represents the replacement control value; E 0 Represents the pre-input longitude data; G 0 represents the pre-input latitude data; 1 represents the first preset value; Y 2 represents the second preset value; according to the characteristic of the step function u() (when the value in the bracket is greater than or equal to 0, the function value is equal to 1; when the value in the bracket is less than 0, the function value is equal to 0);), the relationship between the difference between the longitude data and the pre-input longitude data and the first preset value and the relationship between the difference between the latitude data and the pre-input latitude data and the second preset value are quantitatively judged, that is, u(EE in the formula 0 -Y 1 )+u(GG 0 -Y 2 ), so that the longitude data and latitude data can be judged whether they need to be replaced according to the replacement control value K, and then the formula in That is, by replacing the sign of the control value K, it is determined which data of the longitude data and the latitude data to replace. The specific steps include:

[0077] When K=0, it means that the difference between the longitude data and the pre-input longitude data is greater than the first preset value and the difference between the latitude data and the pre-input latitude data is less than the second preset value, then neither the longitude data nor the latitude data is replaced;

[0078] When K=-1, it means that the difference between the latitude data and the pre-input latitude data is greater than a second preset value, and the pre-input latitude data is replaced by the latitude data;

[0079] When K=1, it means that the difference between the longitude data and the pre-input longitude data is greater than a first preset value, and the pre-input longitude data is replaced by the longitude data;

[0080] When K=2, it means that the difference between the longitude data and the pre-input longitude data is greater than the first preset value and the difference between the latitude data and the pre-input latitude data is greater than the second preset value, then the longitude data replaces the pre-input longitude data and the latitude data replaces the pre-input latitude data.

[0081] Based on the above technical scheme, the characteristic value of the name information is obtained by step A1, the purpose of which is to better traverse and match the database by the characteristic value, and the characteristic value can be used to compare the characteristic value of the name information and the characteristic value of the name information in the database when obtaining the similarity value between each information in the database and the name information in step A2, so as to optimize the result according to the difference in comparison, so that the result obtained is more accurate and the similarity effect is more obvious; the similarity value of each information in the database and the name information is obtained by step A2, the purpose of which is to obtain the name information in the database closest to the name information according to the similarity value, so as to determine the corresponding longitude data and latitude data, and finally, the replacement control value is obtained by step A3, the purpose of which is to use the replacement control value to combine with a computer for control, and the corresponding operation can be performed after judgment. Compared with the absence of the formula and steps, the formula and steps add the effect of automation, and the use of the formula for judgment and selection is more efficient and convenient.

The automatic positioning correction method according to claim 5, characterized in that: Step A3: Use formula (3) to analyze the relationship between the difference between the longitude data obtained in step A2 and the pre-input longitude data and the first preset value, and the relationship between the difference between the latitude data obtained in step A2 and the pre-input latitude data and the second preset value, to obtain the replacement control value Wherein K represents the replacement control value; E0 represents the pre-input longitude data; G0 represents the pre-input latitude data; Y1 represents the first preset value; Y2 represents the second preset value; according to the characteristic that the function value is equal to 1 when the value in the bracket is greater than or equal to 0 and the function value is equal to 0 when the value in the bracket is less than 0 corresponding to the step function u(), the relationship between the difference between the longitude data and the pre-input longitude data and the first preset value and the relationship between the difference between the latitude data and the pre-input latitude data and the second preset value are quantitatively judged, that is, u(E-E0-Y1)+u(G-G0-Y2) in the formula, so as to judge whether the longitude data and the latitude data need to be replaced based on the replacement control value K, and then use the formula That is, by replacing the sign of the control value K, it is determined which data of the longitude data and the latitude data to replace. The specific steps include: When K=0, it means that the difference between the longitude data and the pre-input longitude data is greater than the first preset value and the difference between the latitude data and the pre-input latitude data is less than the second preset value, then neither the longitude data nor the latitude data is replaced; When K=-1, it means that the difference between the latitude data and the pre-input latitude data is greater than a second preset value, and the pre-input latitude data is replaced by the latitude data; When K=1, it means that the difference between the longitude data and the pre-input longitude data is greater than a first preset value, and the pre-input longitude data is replaced by the longitude data; When K=2, it means that the difference between the longitude data and the pre-input longitude data is greater than the first preset value and the difference between the latitude data and the pre-input latitude data is greater than the second preset value, then the longitude data replaces the pre-input longitude data and the latitude data replaces the pre-input latitude data.

7. An intelligent control box, characterized in that: An automatic positioning and correction system comprising any one of claims 1 to 4, characterized in that the positioning device is arranged in the intelligent control box.
