Description

Technical Field

[0001] The present invention relates to the field of surveying and mapping management technology, and in particular to a land surveying and mapping data intelligent analysis and management system. Background Art

[0002] Land surveying and mapping is an important foundation for obtaining land information and ensuring the rational use and management of land. With the rapid development of information technology, the amount of data generated by land surveying and mapping is becoming increasingly large, and the types of data are becoming increasingly complex. Traditional surveying and mapping data management methods can no longer meet the needs of modern land management. Against this backdrop, land surveying and mapping data intelligent analysis and management systems have emerged to improve the processing efficiency, analysis accuracy, and management level of land surveying and mapping data.

[0003] In land surveying and mapping, data accuracy and reliability are of vital importance. Despite the continuous advancement of modern surveying and mapping technology, some key data still require manual verification due to the complexity and diversity of land surveying and mapping work.

[0004] In the processing of land surveying and mapping data, key encryption technology is widely used to protect the security of data during transmission and storage. However, when transmitting critical data that needs to be verified to manual verification, the current common practice is to use the key generation method for land surveying data to generate the key for the critical data, and then transmit the critical data;

[0005] Keys are crucial information for data encryption and decryption, and their security directly determines the security of the data. Every time a key is transmitted across the network, it is like exposing a "key" to a treasure trove of data in cyberspace. When the existing key generation method is used, the frequency of key transmissions across the network increases, and the probability of key theft also increases significantly.

[0006] In order to solve the above problems, the present invention proposes a solution. Summary of the Invention

[0007] The purpose of the present invention is to provide a land surveying and mapping data intelligent analysis and management system in order to solve the problems raised in the above background technology.

[0008] The present invention provides a land surveying and mapping data intelligent analysis and management system, comprising the following steps:

[0009] Step 1: After receiving the target mapping data, the communication management module executes a preset mapping relationship script to temporarily generate a mapping relationship document for converting the target mapping data. The mapping relationship document contains eight mapping sets, and any mapping set stores two groups of four-bit binary numbers from left to right;

[0010] Step 2: After generating the mapping relationship document, the communication management module performs a secure conversion on the target surveying and mapping data according to the mapping relationship document and a preset conversion rule to obtain surveying and mapping communication data and its flag bit data;

[0011] Step 3: After receiving the transmitted surveying and mapping communication data and its flag data, the peer verification center first executes the preset mapping relationship script to obtain a mapping relationship document;

[0012] Step 4: The peer verification center restores the surveying and mapping communication data according to the mapping relationship document and the flag data to obtain target surveying and mapping data, and stores the target surveying and mapping data.

[0013] Furthermore, in step one, two groups of four-bit binary numbers in any mapping set contained in the mapping relationship document satisfy the equation -n=n+1, where n is the decimal number of the four-bit binary number that is arranged in the first position from left to right in the mapping set.

[0014] Furthermore, in step 1, the four-digit binary numbers that are first arranged from left to right in the eight mapping sets included in the mapping relationship document are four-digit binary numbers of the numbers 0, 1, 2, ..., 7 respectively.

[0015] Furthermore, the conversion rules for securely converting surveying and mapping communication data and its flag data are as follows:

[0016] S11: performing binary conversion on the target surveying and mapping data, and calibrating the converted data as first processed data;

[0017] S12: The first processed data as a set of four characters to obtain a plurality of conversion arrays, and according to the position of each conversion array in the first processed data, from left to right: all groups of conversion arrays are marked as A1, A2, ..., Aa, a ≥ 1;

[0018] S13: Reading the mapping relationship document and extracting a mapping set including the conversion array A1 therefrom. It should be noted that the aforementioned description of including the conversion array A1 actually refers to finding a mapping set in the mapping relationship document that contains a set of four-bit binary numbers that are consistent with the conversion array A1.

[0019] S14: If the first character arranged from left to right in the mapping set is the conversion array A1, character 1 is used as the flag character of the conversion array A1, and then another set of four-bit binary numbers other than the conversion array A1 is extracted from the mapping set, and the four-bit binary numbers are used as the communication array of the conversion array A1; conversely, if the first character arranged from left to right in the mapping set is not the conversion array A1, character 0 is first used as the flag character of the conversion array A1, and then the communication array of the conversion array A1 is generated according to a preset generation rule;

[0020] S15: Obtain the communication arrays and flag characters of the conversion arrays A2, A3, ..., Aa in sequence according to S14;

[0021] The communication arrays of the conversion arrays A1, A2, ..., Aa are spliced ​​in the order of the conversion arrays A1, A2, ..., Aa to obtain the surveying and mapping communication data. Similarly, the flag characters of the conversion arrays A1, A2, ..., Aa are spliced ​​in the order of the conversion arrays A1, A2, ..., Aa to obtain the flag data of the surveying and mapping communication data.

[0022] Furthermore, before proceeding to step 1, you need to perform the following steps:

[0023] The information retrieval module retrieves the target surveying and mapping data from the target repository according to the preset retrieval whitelist and transmits it to the communication management module. The target repository is used to store the land surveying and mapping data of the target area. The retrieval whitelist contains the attribute information of several surveying and mapping data preset by the management personnel that need to be manually checked and verified.

[0024] Compared with the existing technology, it has the following beneficial effects:

[0025] The present invention retrieves target surveying and mapping data from a target repository according to a retrieval whitelist by setting an information retrieval module. After receiving the target surveying and mapping data, the communication management module executes a mapping relationship script to instantly generate a mapping relationship document. The target surveying and mapping data is converted into surveying and mapping communication data and its flag data according to the mapping relationship document. The surveying and mapping communication data and its flag data are transmitted, and the mapping relationship document is deleted after the transmission. In this way, on the one hand, the security of the mapping relationship document used for conversion is guaranteed, and the risk of information leakage caused by the retention of the document is avoided, thereby providing a guarantee for the transmission security of the target surveying and mapping data. Similarly, the documents that are no longer needed are deleted in a timely manner, thereby effectively releasing system resources and improving the operating efficiency of the entire system. On the other hand, the conversion process is independent, and the encryption method of the key is broken away.

[0026] In the process of converting target surveying and mapping data, the present invention obtains a flag character of each conversion array based on a plurality of conversion arrays obtained from the target surveying and mapping data according to the position of each conversion array in the mapping set in the mapping relationship document. At the same time, all conversion arrays with a flag character of 0 are extracted and re-cut to obtain a first inner array and a second inner array of the conversion array. Two matches are performed in the mapping set based on the first inner array and the second inner array, and two groups of four-bit binary numbers are randomly selected from the plurality of groups of four-bit binary numbers obtained after the matching as the communication arrays of the conversion array. This method not only enables the communication array of the conversion array to have two character lengths, but also adds a random feature to the communication array. Finally, the communication arrays of all conversion arrays are spliced ​​to obtain surveying and mapping communication data. In this way, the confidentiality and security of the surveying and mapping communication data are enhanced, and the transmission security of the target surveying and mapping data is further guaranteed.
