[0034] Input the first string and the second string into the string comparison function; if the output result of the string comparison function is 0, the comparison result is that the first string is consistent with the second string; if the output result of the string comparison function If it is not 0, the comparison result is that the first character string is inconsistent with the second character string. The above-mentioned string comparison function may be a strcmp() function in C language, a function that can implement string comparison in C language or Java language, or other algorithms that can implement string comparison.
[0035] In a specific implementation manner, the above-mentioned first character string is obtained by the base station operating on the original observation data based on a hash function. The second character string is obtained by calculating the original observation data sent by the base station by the central solution software based on the hash fun...

The invention, which relates to the technical field of network RTKs, provides a method and device for determining network RTK data security and electronic equipment. The method comprises the steps: receiving a first character string that is transmitted by a reference station in a network RTK through a blockchain network and is determined by the reference station based on original observation data;receiving a second character string that is sent by network RTK center resolving software through the blockchain network and is determined based on original observation data sent to the central resolving software by the reference station; comparing the first character string with the second character string to obtain a comparison result; and if the comparison result is that the first character string is consistent with the second character string, determining that the original observation data are not tampered in data transmission. According to the invention, whether the original observationdata are tampered in data transmission or not can be judged, so that the security of the original observation data after transmission is determined.
Description
Technical field [0001] The present invention relates to the technical field of network RTK, in particular to a method, device and electronic equipment for determining network RTK data security. Background technique [0002] The high-precision reference station of the network RTK obtains the Beidou / GNSS satellite signals in real time, and transmits the original observation data to the network RTK central calculation software through the cellular network. However, the transmission of the original observation data through the cellular network has the risk of data tampering or leakage. Since the authenticity of the original observation data is very important to the network RTK service, it is very necessary to judge the safety of the original observation data after transmission. Summary of the invention [0003] The purpose of the embodiments of the present invention is to provide a method, device, and electronic equipment for determining the security of network RTK data, which can det...
