In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the embodiments, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In consideration of the problems of poor safety and low accuracy of the coordinates of the reference station in the existing network RTK center resolving software, the invention provides the method and the device for monitoring the reference station in the network RTK center resolving software, and the safety and the accuracy of the data of the reference station in the network RTK center resolving software can be effectively improved.
To facilitate understanding of the embodiment, first, a detailed description is given of a method for monitoring a reference station in network RTK center solution software disclosed in the embodiment of the present invention, referring to a flowchart of the method for monitoring a reference station in network RTK center solution software shown in fig. 1, where the method mainly includes the following steps S102 to S108:
and S102, receiving the observation data of the target reference station through the network RTK center resolving software. The reference station is configured to receive Navigation Satellite signals such as a Beidou Satellite, a Global Positioning System (GPS) Satellite or a Global Navigation Satellite System (GNSS) Satellite, and obtain observation data in a Receiver Independent Exchange Format (RINEX Format), and the 4G module in the Receiver uploads the original observation data to the network RTK center calculation software in practical application. In one implementation, the embodiments of the present invention may be applied to an electronic device, where the electronic device may be installed with network RTK center solution software, and receive observation data through the network RTK center solution software.
And step S104, carrying out post-processing on the observation data to obtain coordinate data corresponding to the target reference station. In practical application, the central calculation software stores the acquired original observation data in a file of a server according to a certain format (such as a year, month and day format), and post-processing software is used for processing observation data continuously observed for several days at each reference station to obtain millimeter-level high-precision coordinate data corresponding to the reference stations.
And step S106, encrypting the coordinate data to obtain a first coordinate certificate corresponding to the coordinate data. In practical application, block chain encryption technologies such as a hash function and the like can be adopted to encrypt coordinate data of the target reference station to obtain a fixed-length character string, and the fixed-length character string is used as a first coordinate certificate corresponding to the coordinate data.
Step S108, the coordinate data are saved to a local storage area, and the first coordinate certificate is saved to a cloud storage area. The cloud storage area may include a private cloud platform or a common cloud platform, and generally, the cloud storage area has higher security, and the first coordinate certificate stored in the cloud storage area is not easily tampered.
Step S110, if a coordinate monitoring instruction sent by the target reference station is received, the coordinate data of the target reference station stored in the local storage area is encrypted to obtain a second coordinate certificate corresponding to the coordinate data, and the second coordinate certificate is stored in the cloud storage area. The coordinate detection instruction may carry information such as a name or a number of the target reference station, so as to obtain data of the reference station from the local storage area based on the information such as the name or the number.
In specific implementation, the coordinate data of the target reference station stored in the local storage area may also be encrypted by using a block chain encryption technology such as a hash function, so as to obtain the second coordinate certificate. The second coordinate certificate is uploaded and stored to the cloud storage area, so that the coordinate data of the target reference station can be monitored.
Step S112, comparing the first coordinate certificate and the second coordinate certificate corresponding to the coordinate data stored in the cloud storage area to monitor the coordinate data of the target reference station based on the coordinate comparison result. In practical application, the coordinate data is encrypted to obtain a unique digital certificate (including a coordinate certificate), if the coordinate data is the same, the encrypted coordinate certificate is also the same, and different coordinate data is encrypted to obtain different digital certificates, so that in one implementation, the coordinate data of the target reference station can be monitored based on a first coordinate certificate and a second coordinate certificate corresponding to the coordinate data of the target reference station stored in a cloud storage area, and whether the coordinate data of the target reference station is tampered or not can be monitored by comparing whether the first coordinate certificate and the second coordinate certificate are the same or not.
The method for monitoring the reference station in the network RTK center resolving software provided by the embodiment of the invention comprises the steps of firstly receiving observation data of a target reference station, then post-processing the observation data to obtain coordinate data corresponding to the target reference station, encrypting the coordinate data to obtain a first coordinate certificate corresponding to the coordinate data, and save the coordinate data to a local storage area and the first coordinate certificate to a cloud storage area, if a coordinate monitoring instruction sent by the target reference station is received, encrypting the coordinate data of the target reference station stored in the local storage area to obtain a second coordinate certificate corresponding to the coordinate data, storing the second coordinate certificate in the cloud storage area, and monitoring the coordinate data of the target reference station based on a coordinate comparison result by comparing the first coordinate certificate and the second coordinate certificate corresponding to the coordinate data stored in the cloud storage area. In addition, the embodiment of the invention also monitors the coordinate data of the target reference station based on the first coordinate certificate and the second coordinate certificate, can monitor whether the coordinate data of the target reference station is falsified in time, and further effectively improves the reliability of the coordinate of the reference station.
As for the step S106, in the embodiment of the present invention, the coordinate data of the reference station may be encrypted to obtain the first coordinate certificate corresponding to the coordinate data of the reference station, and in a specific implementation manner, when the observation data of the reference station is received, the observation data may be post-processed to obtain the coordinate data, and then the post-processed coordinate data may be encrypted to obtain the first coordinate certificate of the reference station, and the coordinate data and the first coordinate certificate corresponding to the coordinate data are respectively stored in the local storage area and the cloud storage area. The block chain encryption algorithm includes a hash function algorithm, for example, coordinate data of the reference station is used as an argument of the hash function, so as to perform hash function processing on the coordinate data of the reference station, thereby obtaining a first coordinate certificate of security authentication corresponding to the coordinate data of the reference station. In addition, in step S110, the coordinate data of the target reference station stored in the local storage area may also be encrypted by using a block chain encryption algorithm to obtain a second coordinate certificate corresponding to the coordinate data, and the second coordinate certificate may be uploaded to the cloud storage area.
The embodiment of the invention exemplarily provides a specific implementation mode for monitoring the coordinate data of a target reference station based on a first coordinate certificate and a second coordinate certificate corresponding to the coordinate data of the target reference station stored in a cloud storage area, and the specific implementation mode can compare the first coordinate certificate and the second coordinate certificate corresponding to the coordinate data of the target reference station stored in the cloud storage area and judge whether the first coordinate certificate and the second coordinate certificate are the same; if so, determining that the coordinate data of the target reference station is not tampered; and if not, determining that the coordinate data of the target reference station is tampered. The first coordinate certificate and the second coordinate certificate are both a string of numbers, and the digital certificates have uniqueness, so that whether the coordinate data of the target reference station stored in the local storage area is tampered can be judged by comparing whether the digital certificates are the same or not.
In practical applications, there are also scenes where observation data needs to be monitored, so the embodiment of the present invention provides a method for monitoring observation data of a reference station, see the following steps (1) to (5): (1) and encrypting the observation data to obtain a first observation data certificate corresponding to the observation data. During specific implementation, a hash function can be used for encrypting the observation data to obtain a first observation data certificate corresponding to the observation data. (2) The observation data is saved to a local storage area, and the first observation data certificate is saved to a cloud storage area. (3) And if an observation data monitoring instruction sent by aiming at the target reference station is received, encrypting the observation data of the target reference station stored in the local storage area to obtain a second observation data certificate corresponding to the observation data, and storing the second observation data certificate in the cloud storage area. The observation data monitoring instruction can carry the name or number of the target reference station, so that the observation data of the target reference station can be conveniently searched from the local storage area, the observation data stored in the local storage area is encrypted by using a hash function, and a second observation data coordinate corresponding to the observation data is obtained. (4) And judging whether a first observation data certificate and a second observation data certificate corresponding to the observation data stored in the cloud storage area are the same. (5) If not, the observation data of the target reference station stored in the local storage area is determined to be tampered.
In one embodiment, after receiving the observation data sent by the reference station, the central calculation software transmits the observation data into the post-processing software so as to perform post-processing on the observation data through the post-processing software, thereby obtaining high-precision coordinate data of the reference station. It can be understood that, after the observation data of the reference station is received, the encryption processing and the post-processing on the observation data and the encryption processing on the coordinate data are started, and the observation data and the coordinate data at this time can be regarded as accurate and untampered data, that is, the first observation data certificate is obtained on the basis of correct observation data and the first coordinate certificate is obtained on the basis of correct coordinate data.
On the basis of the foregoing embodiments, the embodiments of the present invention provide the following implementation manners: if monitoring whether the observation data of the target reference station stored in the local storage area is tampered, encrypting the observation data of the target reference station in the local storage area by using a hash function to obtain a second observation data certificate corresponding to the observation data, comparing the second observation data certificate with a first observation data certificate corresponding to the observation data in the cloud storage area, and if the first observation data certificate is different from the second observation data certificate, determining that the observation data of the target reference station is tampered. Similarly, if the coordinate data of the target reference station stored in the local storage area is monitored to be tampered, the coordinate data of the target reference station in the local storage area can be encrypted to obtain a second coordinate certificate corresponding to the coordinate data, the second coordinate certificate is compared with a first coordinate certificate corresponding to the coordinate data in the cloud storage area, and if the first coordinate certificate and the second coordinate certificate are different, the coordinate data of the target reference station is determined to be tampered. And (III) if the coordinate data of the target reference station stored in the local storage area is monitored to be tampered, acquiring the observation data of the target reference station from the local storage area, performing post-processing on the observation data to obtain corresponding coordinate data, performing encryption processing on the coordinate data to obtain a corresponding second coordinate certificate, and comparing a first coordinate certificate and the second coordinate certificate corresponding to the coordinate data of the target reference station in the cloud storage area to judge whether the coordinate data of the target reference station is tampered.
In addition, the cloud storage area also stores observation data and coordinate data of the target reference station, and the embodiment of the invention also can modify and store the observation data of the target reference station stored in the local storage area by using the observation data of the target reference station stored in the cloud storage area, and modify and store the coordinate data of the target reference station stored in the local storage area by using the coordinate data of the target reference station stored in the cloud storage area. The modified observation data and coordinate data of the target reference station can be input into the center calculation software, so that the center calculation software can well complete tasks depending on the observation data and coordinate data of the target reference station.
In another embodiment, after the observation data and the coordinate data of the target reference station are modified, the modified observation data and coordinate data of the target reference station can be displayed. For example, the modified observation data and coordinate data of the target reference station are displayed for the user through a preset page in the central calculation software, or the modified observation data and coordinate data are sent to a designated associated terminal, so that the user can conveniently view the modified observation data and coordinate data of the target reference station by using the associated terminal.
To facilitate understanding of the method for monitoring a reference station provided in the foregoing embodiment, another method for monitoring a reference station is also provided in the present embodiment, and referring to a schematic flow chart of another method for monitoring a reference station in network RTK center solution software shown in fig. 2, the method mainly includes the following steps S202 to S208:
step S202, obtaining the original observation data (i.e., the aforementioned observation data) of the reference station by the center solution software. In practical application, after the original observation data of the reference station is acquired through the central calculation software, the central calculation software stores the original observation data to the local storage area in a specified format.
Step S204, performing hash function processing on the original observation data to obtain a first observation data certificate corresponding to the original observation data, and saving the original observation data in a local storage area and saving the original observation data and the first observation data certificate in a database (where the database may include the cloud storage area). In order to improve the security of the original observation, the original observation data can be encrypted by using a block chain technology to obtain a first observation data certificate corresponding to the original observation data.
And step S206, processing the original data by utilizing post-processing software to obtain the coordinate data of the reference station. The post-processing software can perform post-processing on the original observation data, so that high-precision coordinate data of the reference station can be obtained.
Step S208, processing the coordinate data of the reference station by using a block chain technology to obtain a first coordinate certificate corresponding to the coordinate data, storing the coordinate data in a local storage area, and storing the coordinate data and the first coordinate certificate in a database. In one embodiment, the coordinate data may be input into a hash function, resulting in a first coordinate certificate that the hash function outputs for the coordinate data.
Step S210, if the coordinate data of the reference station is monitored, performing hash function processing on the coordinate data stored in the local storage area to obtain a second coordinate certificate, and uploading the second coordinate certificate to the cloud storage area.
Step S212, comparing the first coordinate certificate and the second coordinate certificate to obtain a comparison result. If the coordinate data of the target reference station in the local storage area is not tampered, the first coordinate certificate and the second coordinate certificate are both obtained by performing hash function processing on the coordinates of the target reference station, and therefore the first coordinate certificate and the second coordinate certificate in the comparison result are the same; if the coordinate data of the target reference station in the local storage area is tampered, the first coordinate certificate is obtained by performing hash function processing on the coordinate data before tampering, and the second coordinate certificate is obtained by performing hash function processing on the coordinate data after tampering, at this time, the first coordinate certificate and the second coordinate certificate in the comparison result are different.
And step S214, judging whether the coordinate data of the reference station is tampered according to the comparison result. If yes, go to step S216; if not, the process is ended. And if the digital certificates are different, determining that the coordinate data of the reference station is tampered.

Step S218, if the observation data of the reference station is monitored, hash function processing is performed on the observation data stored in the local storage area to obtain a second observation data certificate, and the second observation data certificate is uploaded to the cloud storage area.
Step S220, comparing the first observation data certificate and the second observation data certificate to obtain a comparison result. Similarly, if the observation data of the target base station in the local storage area is not tampered, the first observation data certificate and the second observation data certificate are both obtained by performing hash function processing on the observation data of the target base station, so that the first observation data certificate and the second observation data certificate in the comparison result are the same; if the observation data of the target reference station in the local storage area is tampered, the first observation data certificate is obtained by performing hash function processing on the observation data before tampering, and the second observation data certificate is obtained by performing hash function processing on the observation data after tampering, at this time, the first observation data certificate and the second observation data certificate in the comparison result are different.
Step S222, judging whether the observation data of the reference station is tampered according to the comparison result. If yes, go to step S224; if not, the process is ended.
Step S224, modifying the observation data of the reference station in the local storage area according to the observation data of the reference station in the cloud storage area, and displaying the modified observation data of the reference station.
In addition, the method can be applied to safety monitoring of geological disasters, safety monitoring of high-precision geological disasters is processed through the block chain technology, the problem that data is tampered or centralized can be effectively solved, and a basis is provided for relevant departments to check the reliability of the data.
In summary, after the hash function processing is performed on the coordinates of the reference station, any change performed on the coordinates of the reference station can be identified, so that the safety and reliability of the coordinates of the reference station are improved. In addition, the embodiment of the invention can also process the original observation data by using the block chain technology, thereby improving the safety and reliability of the original observation data.
