Description

Technical Field

[0001] The present invention relates to the technical field of data management, and in particular to a method for managing railway communication geographic information data. Background Art

[0002] Geographic Information System is sometimes called "Geo-information System". It is a specific and very important spatial information system. It is a technical system that collects, stores, manages, calculates, analyzes, displays and describes the geographical distribution data in the entire or part of the earth's surface (including the atmosphere) space with the support of computer hardware and software systems. Location and geographic information are both the core and the foundation of LBS. A simple longitude and latitude coordinate will only be recognized and understood by users after it is placed in specific geographic information and represents a certain place, sign, and direction. After users obtain location information through relevant technologies, they also need to understand the geographical environment in which they are located, query and analyze environmental information, so as to provide information support and services for user activities.

[0003] The existing technology has the following problems:

[0004] The existing railway information data cannot be set with corresponding usage permissions during management, which makes it easy for people to retrieve and access it at will. The data is easily lost and cannot be backed up. The security is low and the management is difficult. At the same time, railway information data cannot be classified and managed according to the number of accesses and usage efficiency, resulting in poor management results. Summary of the invention

[0005] The purpose of the present invention is to provide a railway communication geographic information data management method to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A railway communication geographic information data management method comprises the following steps:

[0008] Use Beidou collectors to obtain geographic information data of railway lines, railway terrain, and surrounding environment at various locations on the railway;

[0009] Based on the acquired geographic information data, the data is entered into the database of the communication center;

[0010] The communication center encrypts the input data and notifies the encryption key to each railway bureau;

[0011] The railway bureau inputs the secret key for decryption, and the database determines whether the input secret key is correct. If so, it accesses the database of the communication center. If not, it returns to the secret key input interface;

[0012] The database classifies and manages geographic information data with more access times and geographic information data with less access times according to the number of access times of each geographic information data;

[0013] The Communication Center regularly conducts quality checks on railway geographic information data, and promptly repairs and improves any problems found to ensure data quality;

[0014] Establish a geographic information data update and maintenance mechanism, update and maintain data regularly, and ensure the timeliness and accuracy of the data.

[0015] A further improvement of the technical solution of the present invention is that: based on the acquired geographic information data, entering the data into the database of the communication center specifically includes: preliminarily organizing the acquired geographic information data of the railway line, railway terrain, and surrounding environment, comparing and verifying the organized data with the actual geographic information, and after determining that the collected geographic information is accurate, entering the geographic information data into the database of the communication center according to the defined data structure and fields.

[0016] A further improvement of the technical solution of the present invention is that the communication center encrypts the input data and notifies the encryption key to each railway bureau, which specifically includes the following steps:

[0017] A1. The communication center retrieves the newly entered geographic information data of railway lines, railway terrain, and surrounding environment from the database;

[0018] A2. Based on the retrieved geographic information data, the communication center uses the AES algorithm to encrypt the geographic information data and obtains the ciphertext through multiple rounds of iterative encryption;

[0019] A3. The communication center uses the communication system to send the secret key to each railway bureau, reminding each railway bureau to save the secret key for later retrieval of geographic information data.

[0020] A further improvement of the technical solution of the present invention is that: the railway bureau inputs the secret key for decryption, and the database determines whether the input secret key is correct. If so, the database of the communication center is accessed. If not, the interface for inputting the secret key is returned, which specifically includes the following steps:

[0021] B1. When each railway bureau needs to retrieve geographic information data from the communication center database, it inputs the key received from the communication center from the key input interface;

[0022] B2. The communication center database determines whether the secret key input by the railway bureau is correct. If it is correct, the railway bureau is allowed to access the geographic information in the database. If it is wrong, it automatically returns to the interface for inputting the secret key.

[0023] B3. In case of failure in entering the secret key, the Railway Administration needs to communicate with the Communication Center in a timely manner to obtain the accurate secret key.

[0024] A further improvement of the technical solution of the present invention is that: the database classifies and manages geographic information data with more access times and geographic information data with less access times according to the access times of each geographic information data, specifically including: in the same quarter, the database obtains the access times of each geographic information data, establishes an access times determination model, classifies and manages whether each geographic information data is frequently accessed according to the access times determination model, moves geographic information with more access times to a convenient location in the database for retrieval, and moves geographic information with less access times to an infrequently used retrieval location in the database;

[0025] The specific calculation formula for the visit number determination model is:

[0026] Y i =m i α1+n i α2+t i α3

[0027] Where Y i is the total value of the i-th geographic information access, m i is the number of visits to the i-th geographic information railway line, α i is the weight of the i-th geographic information railway line, n i is the number of visits to the i-th geographic information railway terrain, α2 is the weight of the i-th geographic information railway terrain, t i is the number of visits to the ith geographic information railway surrounding environment, α3 is the weight of the ith geographic information railway surrounding environment;

[0028] The total visit value is greater than The geographic information data of which the total value is less than The geographic information data is recorded as infrequently accessed data;

[0029] Move frequently accessed data to a convenient location in the database, and move infrequently accessed data to a location in the database that is infrequently accessed.

[0030] A further improvement of the technical solution of the present invention is that the communication center regularly conducts quality checks on railway geographic information data, and promptly repairs and improves problems found to ensure data quality. Specifically, the communication center conducts regular quality checks on the data on a monthly basis, and records the content and inspection time of each update, promptly repairs and improves problematic areas and keeps real-time records to ensure later traceability and management.

[0031] A further improvement of the technical solution of the present invention is that: the establishment of a geographic information data update and maintenance mechanism, regular data updates and maintenance, to ensure the timeliness and accuracy of the data specifically includes: on a daily basis, the Beidou collector collects each geographic information data in real time, and inputs the collected data into the database, the database promptly determines whether there is a deviation or change from the previously entered data, and if there is a deviation, promptly notifies the communication center, and the staff of the communication center promptly changes and encrypts the newly added data to ensure that the data remains accurate and consistent with the actual geographic information.

[0032] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0033] 1. The present invention provides a method for managing geographic information data of railway communications. The communication center retrieves the newly entered geographic information data of railway lines, railway terrain, and surrounding environment from the database, and uses the AES algorithm to encrypt the geographic information data. Through multiple rounds of iterative encryption, ciphertext is obtained, thereby realizing timely encryption of the geographic information data and ensuring the security of the data information. The communication center uses the communication system to send the secret key to each railway bureau. When each railway bureau needs to retrieve the geographic information data from the communication center database, it inputs the secret key received from the communication center from the secret key input interface. If the secret key is correct, the database can be accessed, further ensuring the security of the data and the function of data standardization management.

[0036] The present invention is further described in detail below in conjunction with embodiments:

[0037] like Figure 1 As shown, the present invention provides a railway communication geographic information data management method, comprising the following steps:

[0038] Use Beidou collectors to obtain geographic information data of railway lines, railway terrain, and surrounding environment at various locations on the railway;

[0039] Based on the acquired geographic information data, the data is entered into the database of the communication center;

[0040] The communication center encrypts the input data and notifies the encryption key to each railway bureau;

[0041] The railway bureau inputs the secret key for decryption, and the database determines whether the input secret key is correct. If so, it accesses the database of the communication center. If not, it returns to the secret key input interface;

[0042] The database classifies and manages geographic information data with more access times and geographic information data with less access times according to the number of access times of each geographic information data;

[0043] The Communication Center regularly conducts quality checks on railway geographic information data, and promptly repairs and improves any problems found to ensure data quality;

[0044] Establish a geographic information data update and maintenance mechanism, update and maintain data regularly, and ensure the timeliness and accuracy of the data.

[0045] Based on the acquired geographic information data, entering the data into the database of the communication center specifically includes: preliminarily organizing the acquired geographic information data of the railway line, railway terrain, and surrounding environment, comparing and verifying the organized data with the actual geographic information, and after confirming that the collected geographic information is accurate, entering the geographic information data into the database of the communication center according to the defined data structure and fields.

[0046] The communication center encrypts the input data and notifies the encryption key to each railway bureau, which specifically includes the following steps:

[0047] A1. The communication center retrieves the newly entered geographic information data of railway lines, railway terrain, and surrounding environment from the database;

[0048] A2. Based on the retrieved geographic information data, the communication center uses the AES algorithm to encrypt the geographic information data and obtains the ciphertext through multiple rounds of iterative encryption;

[0049] A3. The communication center uses the communication system to send the secret key to each railway bureau, reminding each railway bureau to save the secret key for later retrieval of geographic information data.

[0050] The railway bureau inputs the secret key for decryption, and the database determines whether the input secret key is correct. If so, it accesses the database of the communication center. If not, it returns to the secret key input interface. The specific steps include:

[0051] B1. When each railway bureau needs to retrieve geographic information data from the communication center database, it inputs the key received from the communication center from the key input interface;

[0052] B2. The communication center database determines whether the secret key input by the railway bureau is correct. If it is correct, the railway bureau is allowed to access the geographic information in the database. If it is wrong, it automatically returns to the interface for inputting the secret key.

[0053] B3. In case of failure in entering the secret key, the Railway Administration needs to communicate with the Communication Center in a timely manner to obtain the accurate secret key.

[0054] The communication center retrieves the newly entered geographic information data of railway lines, railway terrain, and surrounding environment from the database, and encrypts the geographic information data using the AES algorithm. Through multiple rounds of iterative encryption, the ciphertext is obtained, thereby realizing timely encryption of the geographic information data and ensuring the security of data information. The communication center uses the communication system to send the secret key to each railway bureau. When each railway bureau needs to retrieve geographic information data from the communication center database, it enters the secret key received from the communication center from the secret key input interface. If the secret key is correct, the database can be accessed, further ensuring the security of the data and the function of data standardization management.

[0055] The database classifies and manages geographic information data with more frequent accesses and geographic information data with less frequent accesses according to the number of accesses to each geographic information data. Specifically, the database obtains the number of accesses to each geographic information data in the same quarter, establishes a model for determining the number of accesses, and classifies and manages whether each geographic information data is frequently accessed according to the model for determining the number of accesses, moves geographic information with more frequent accesses to a convenient location in the database, and moves geographic information with less frequent accesses to an infrequently accessed location in the database;

[0056] The specific calculation formula for the visit number determination model is:

[0057] Y i =m i α1+n i α2+t i α3

[0058] Where Y i is the total value of the i-th geographic information access, m i is the number of visits to the i-th geographic information railway line, α i is the weight of the i-th geographic information railway line, n i is the number of visits to the i-th geographic information railway terrain, α2 is the weight of the i-th geographic information railway terrain, t i is the number of visits to the ith geographic information railway surrounding environment, α3 is the weight of the ith geographic information railway surrounding environment;

[0059] The total visit value is greater than The geographic information data of which the total value is less than The geographic information data is recorded as infrequently accessed data;

[0060] Move frequently accessed data to a convenient location in the database, and move infrequently accessed data to a location in the database that is infrequently accessed.

[0061] The database obtains the number of visits to each geographic information data, establishes a model to determine the number of visits, and classifies and manages each geographic information based on whether it is frequently visited. The geographic information with a high number of visits is moved to a convenient location in the database, and the geographic information with a low number of visits is moved to an infrequently used retrieval location in the database, which facilitates the subsequent rapid retrieval by the railway bureau and the communication center's management of the overall data, thereby improving management efficiency.

[0062] The communication center regularly conducts quality checks on railway geographic information data, and promptly repairs and improves problems found to ensure data quality. Specifically, the communication center conducts regular quality checks on the data on a monthly basis, and records the content and inspection time of each update, promptly repairs and improves problematic areas and keeps real-time records to ensure later traceability and management.

[0063] Among them, a geographic information data update and maintenance mechanism is established to update and maintain the data regularly to ensure the timeliness and accuracy of the data. Specifically, on a daily basis, the Beidou collector collects each geographic information data in real time and enters the collected data into the database. The database promptly determines whether there is any deviation or change from the previously entered data. If there is any deviation, it will be notified to the communication center in time. The staff of the communication center will promptly change and encrypt the newly added data to ensure that the data remains accurate and consistent with the actual geographic information.

[0064] In summary, the advantages of the present invention are: the communication center uses the AES algorithm to encrypt the geographic information data, and obtains the ciphertext through multiple rounds of iterative encryption, thereby realizing timely encryption of the geographic information data and ensuring the security of the data information. The communication center uses the communication system to send the secret key to each railway bureau. When each railway bureau needs to retrieve the geographic information data from the communication center database, it inputs the secret key received from the communication center from the secret key input interface. Only if the secret key is correct can it access the database, further ensuring the security of the data. The database of the communication center obtains the number of accesses to each geographic information data, establishes a model for determining the number of accesses, and classifies and manages the frequency of access to each geographic information according to the model for determining the number of accesses. The geographic information with more accesses is moved to a convenient location in the database for retrieval, and the geographic information with fewer accesses is moved to an infrequently used retrieval location in the database, which is convenient for subsequent railway bureaus to quickly retrieve and also convenient for the communication center to manage the overall data.

[0065] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
