Description

Technical Field

[0001] This invention relates to the field of environmental quality data processing, and in particular to an environmental quality data management system, method, and storage medium. Background Technology

[0002] Environmental quality data refers to various indicators and parameters that record and reflect the environmental conditions of a specific area, including air quality index, water quality test results, soil pollution levels, noise levels (decibels), and greenhouse gas concentrations. Environmental quality data is crucial for formulating environmental protection policies, maintaining public health and safety, optimizing urban planning, conducting climate change research, and maintaining ecological balance. Large-scale environmental quality data can be used for environmental trend analysis, pollution source tracing, ecological risk assessment, developing emission reduction measures, and monitoring the effectiveness of environmental governance, contributing to scientific decision-making and effective management. Existing environmental quality data often involves sensitive access and is typically stored in separate systems, accessed manually or via API transmission when needed.

[0003] In the process of realizing this invention, the inventors realized that the prior art has at least the following technical problems: The lack of data sharing function in existing environmental quality data management systems leads to the inability to seamlessly communicate and share environmental quality data between different institutions or systems, which limits the comprehensiveness and accuracy of environmental information. Repeated data entry is required in different systems, increasing the workload of environmental protection personnel and easily leading to data entry errors. The lack of data auditing function in existing environmental quality data management systems makes it difficult to trace and audit the modification and access of environmental quality data. This may lead to risks such as data tampering, abuse and illegal access, which damage the relevant interests and the reliability of environmental quality data, and bring certain security risks to sensitive data.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0057] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] Please see Figure 1 ,like Figure 1 As shown, Figure 1 This is a schematic diagram of an application environment for an environmental quality data management system / method according to an embodiment of the present invention. The environmental quality data management system / method provided in this application can be applied to, for example... Figure 1In the application environment, a blockchain consists of several nodes that can communicate with each other. Each node can be regarded as a block storage, and each block storage is used to store data. Each data node contains all the data. The block storage data has a complete historical record and can be quickly restored and expanded. Blockchains are divided into public chains, private chains, and consortium chains. Public chains are open to any node, and every institution / node can participate in the blockchain computation. Moreover, any institution / node can download and obtain the complete blockchain data. Private chains are blockchains that some organizations do not want anyone to participate in the system and do not disclose it to the public. They are suitable for internal data management, auditing, or open testing of specific institutions. Consortium chains have completely equal permissions for each participating node. They can achieve trusted data exchange without complete mutual trust. Each node in a consortium chain usually has a corresponding entity organization, and can only join or leave the network after authorization. In the process of using the entire blockchain backup system, digital signatures are required. Digital signatures design a hash function, the sender's public key, and the sender's private key. Blockchain has complete distributed storage characteristics. In fact, it is a larger network data storage that uses a data structure in the form of a "hash algorithm" to store basic data.
