[0002] With the intensification of global climate change and the increasing frequency of marine activities, higher requirements are placed on the observation and prediction of marine hydrometeorology. Marine hydrometeorology observation data is not only of great significance for scientific research, but also plays a key role in the fields of marine resource development, maritime transportation, disaster prevention and mitigation, etc. Therefore, it is particularly important to develop an efficient, accurate and safe marine hydrometeorology observation system.

[0003] Traditional ocean hydrological and meteorological observation systems often focus on data collection and simple processing, while neglecting in-depth analysis and secure transmission of data. Traditional observation systems usually lack in-depth analysis and prediction of ocean hydrological and meteorological trends, and cannot provide decision makers with timely and effective early warning information. At the same time, during data transmission, due to the complexity and instability of the network environment, ocean hydrological and meteorological observation data face the risk of leakage and tampering. Summary of the invention

The marine hydrological and meteorological observation system with a safe transmission function according to claim 1 is characterized in that: The relevant information of the ocean hydrological and meteorological observation data corresponding to the target area is encrypted, and the specific analysis is as follows: Identify the characters of the information related to the marine hydrological and meteorological observation data corresponding to the target area, set each character to have and only correspond to a unique numerical value, match the characters in the information related to the marine hydrological and meteorological observation data corresponding to the target area with all the set characters to obtain the corresponding numerical values, and arrange the numerical values ​​in the order of the characters to obtain a character numerical sequence; perform difference calculations on adjacent numerical values ​​to obtain adjacent differences, and when the adjacent differences are greater than the set differences, the middle position of the front and rear numerical values ​​corresponding to the adjacent differences is recorded as the filling position, and the encryption value operation is performed to obtain the character encryption ciphertext, and the character encryption ciphertext is substituted into the preset formula to obtain the encrypted ciphertext of the information related to the marine hydrological and meteorological observation data.
