Description

Technical Field

[0001] The present invention relates to the technical field of rainwater resources, and in particular to a three-dimensional monitoring method and system for rainwater resources. Background Art

[0002] In the current rain and flood resource monitoring system, it is very important to ensure the integrity of the data. Common methods include MD5 checksum and cyclic redundancy check (CRC). MD5 checksum is a widely used cryptographic hash function, which ensures that the data has not been tampered with during transmission or storage by calculating the MD5 hash value of the original data. This method is widely used in data integrity verification because of its simplicity and efficiency;

[0003] CRC is a method of generating a short checksum of fixed length through a specific mathematical algorithm to detect errors that may occur during data transmission. CRC check is particularly effective in identifying single-bit errors or small-scale errors caused by transmission channel noise or interference;

[0004] Although the amount of data transmitted by MD5 and CRC for verification is relatively small, which is of great significance for protecting the integrity of the transmitted data, the amount of data received by the cloud may still become very large considering the continuous data transmission. This huge amount of data puts higher requirements on cloud storage, processing and analysis, causing pressure on the cloud;

[0005] In order to solve the above problems, the present invention proposes a solution. Summary of the invention

[0006] The purpose of the present invention is to provide a three-dimensional monitoring method and system for rainwater resources in order to solve the problems raised in the above background technology;

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] The three-dimensional monitoring method of rainwater resources includes the following steps:

[0009] Step 1: After receiving the transmitted rain and flood resource monitoring data at the current moment, the rain and flood data processing terminal performs binary conversion on the data to obtain the rain and flood monitoring data at the current moment;

[0010] Step 2: Divide every four characters into a group of reference strings, divide the rainwater and flood binary data at the current moment into several groups of reference strings, and then compare the four-bit binary numbers corresponding to the numbers 0 to 7 and their reverse binary numbers for each group of reference strings, and obtain the object string and the verification string of each group of reference strings;

[0011] Step 3: For each group of reference strings, the first two strings of the reference string are sequentially cut out from left to right, and the number 0 or 1 is selected as the shortened character of the corresponding reference string according to the contents of the first two strings;

[0012] Step 4: Obtain the current rainfall and flood monitoring data and rainfall and flood verification data according to the reduced characters of the comparison string and its target string in all the divided groups.

[0013] Furthermore, before completing step 1, you need to perform the following steps:

[0014] The local collection terminal collects the monitoring data of several rainwater parameters in real time to obtain real-time rainwater resource monitoring data, and transmits it to the rainwater data processing terminal. The rainwater parameters include rainfall, river water level and flow, pollutant content in urban rainwater runoff, water temperature and air temperature.

[0015] Furthermore, after completing step 4, you need to perform the following steps:

[0016] The cloud analysis terminal receives the transmitted rainfall and flood monitoring data and rainfall and flood verification data at the current moment and transmits them to the receiving and verification unit;

[0017] After receiving the transmitted rainfall and flood monitoring data and rainfall and flood verification data at the current moment, the receiving and verification unit combines the four-bit binary numbers corresponding to 0 to 7, and performs integrity verification on the rainfall and flood monitoring data at the current moment according to the rainfall and flood verification data. After the verification passes, the rainfall and flood resource monitoring data at the current moment is obtained, and it is transmitted to the resource analysis unit for storage for later analysis of rainfall and flood resources.

[0018] The three-dimensional monitoring system of rainwater resources includes:

[0019] Local data collection terminal, used to collect monitoring data of several rainfall and flood parameters;

[0020] The rainwater and flood data processing terminal is used to process the real-time rainwater and flood resource monitoring data to obtain the corresponding real-time rainwater and flood monitoring data and rainwater and flood verification data;

[0021] Cloud analysis terminal is used to receive, verify and analyze rain and flood resource monitoring data in the cloud.

[0022] Beneficial effects of the present invention:

[0023] The present invention collects rain and flood resource monitoring data in real time through a local collection terminal, and a rain and flood data processing terminal splits the real-time rain and flood resource monitoring data into rain and flood monitoring data and rain and flood verification data based on the real-time rain and flood resource monitoring data, wherein the rain and flood monitoring data is compressed and reduced based on the rain and flood resource monitoring data, and the rain and flood verification data is used to verify the integrity of the rain and flood monitoring data, and the rain and flood verification data is also used to restore the compressed and reduced data. In this way, the verification data used to transmit data not only has the function of verifying the integrity, but also has the function of restoring the transmitted data. In this way, the integrity and accuracy of the rain and flood resource monitoring data are guaranteed, and the rain and flood verification resources are generated based on the rain and flood resource monitoring data, and the number of characters in the rain and flood verification string is consistent with the number of reduced characters of the rain and flood monitoring data. In this way, the transmission of the rain and flood resource monitoring data does not increase the data volume due to the addition of the verification data, thereby ensuring the quality and efficiency of the transmission, and greatly reducing the data capacity of the cloud in the rain and flood monitoring process, effectively alleviating the pressure on the cloud.

[0030] In this embodiment, the rain and flood parameters include but are not limited to rainfall, river water level and flow, pollutant content in urban rainwater runoff, water temperature and air temperature;

If the reduced mapping object B1 of the reference string A1 is the same as the two-digit binary number 00, the number 0 is used as the reduced character of the reference string A1.
