Description

Technical Field

[0001] This invention belongs to the field of engineering safety management technology, and in particular relates to an engineering safety management information system and method that covers unified GNSS calculation. Background Technology

[0002] With the rapid development of BeiDou positioning technology in my country, the Global Navigation Satellite System (GNSS) has ushered in a new era, and BeiDou is increasingly being applied to the field of engineering safety management. Prior to this, GPS from the United States, GLONASS from Russia, and GALILEO from the European Union had already been applied to the field of engineering safety management, especially in safety monitoring and management scenarios such as deformation and displacement, where the results have been remarkable. Currently, it has been widely used in the safety monitoring and management of construction projects such as power, transportation, housing construction, and hydropower stations.

[0003] As GNSS monitoring technology has been widely adopted, many problems have gradually emerged. First, there is a lack of a comprehensive engineering safety management information system that integrates data processing and business applications. Traditionally, processed data is packaged into data files, then stored in folders after processing, rarely and rarely retrieved. This results in a failure to organically integrate processing results with business operations, failing to leverage the data's supporting role. Furthermore, data from different application systems is stored separately, lacking data sharing channels, leading to significant information silos. Second, the equipment management and maintenance system needs optimization. Currently, the management of monitoring points still relies on software provided by the manufacturer, primarily using tables and text for display, which is not intuitive and requires specific software installation, making it inconvenient. Third, the independent transmission of monitoring data by various secondary units within a group company increases network security risks. Each secondary unit independently develops GNSS monitoring and processes data independently, but much of this monitoring data needs to pass through the external network to enter the internal network. Each unit's independent access to data increases the number of internal network interfaces exposed to the external network, increasing the group's network security risks. Fourth, the lack of a unified processing platform and the independent development and application of equipment from various manufacturers mean that users purchasing equipment from different GNSS systems need to learn and operate multiple software programs. Foreign software often uses English labels and has complex functions, making it difficult to learn and operate. Therefore, while considering how to apply GNSS monitoring technology to the field of engineering safety monitoring, we should also consider how to solve the above problems and propose a method that integrates and streamlines the entire business process of GNSS data acquisition, storage, processing, scheduling, and business application. Simultaneously, a comprehensive engineering safety management information system that highly integrates equipment management, data acquisition, data storage, data processing, data scheduling, and business application functions should be established to support this method. Summary of the Invention

[0004] In response to the aforementioned deficiencies and improvement needs in the current development status, this invention provides a construction scheme for an information system covering unified GNSS calculation and engineering safety management. This system can effectively realize equipment management, data transmission, data preprocessing, data storage, data calculation, data scheduling, and comprehensive business applications, providing engineering safety monitoring data support services for various users.

[0005] Therefore, the above-mentioned objective of the present invention is achieved through the following technical solution: An engineering safety management information system encompassing unified GNSS solution calculation, wherein the system comprises a unified entry point, unified solution calculation, online workflow, and integrated application.

[0006] The system includes a device access and management module, a data management and preprocessing module, a baseline calculation and quality assessment module, a data scheduling and access control module, and a comprehensive application module. The device access and management module is used to support site access and online management, and data transmission control; The data management and preprocessing module is used to acquire data transmitted in real time from the monitoring equipment, preprocess the data to prepare for data calculation, and manage the preprocessed data in a unified manner. The baseline calculation and quality assessment module is used to calculate the preprocessed data into commonly used coordinate data or latitude, longitude and elevation data, and to evaluate the reliability of the calculation results. The data scheduling and permission management module is used to manage user access permissions and monitor data by granting differentiated readable and editable permissions based on user level or user category. The integrated application module is used to achieve deep integration of the calculation results and engineering safety monitoring business, perform regularity analysis on the monitoring data, diagnose and monitor dam safety in real time, and provide alarms and emergency handling for abnormal situations.

[0008] As a preferred embodiment of the present invention: the data management and preprocessing module includes a data stream interpretation unit, a quality assessment unit, a hierarchical monitoring unit, a data storage security control unit, a data retransmission unit, and a fast query unit; The data stream interpretation unit is used to convert satellite observation data streams into RINEX standard data format in real time during transmission and store them in the database for later use. The quality assessment unit adopts the QC data quality assessment system and a near real-time task scheduling method to organize and schedule the landing data for a specified duration, and to evaluate the main data quality indicators of each task period in a sliding evaluation. The hierarchical monitoring unit is used to perform data anomaly checks on the main quality indicators of constellation-level and even single-satellite-level data after the data management and preprocessing module has processed a single numerical quality task. It performs preliminary screening of dirty data and removes abnormal datasets to improve the availability of subsequent algorithm solutions.

[0010] As a preferred technical solution of the present invention: Since the data scheduling and permission management module uses a unified entry point, unified calculation and unified storage management for the monitoring data, the data required by different secondary units or parts needs to be obtained from the data center. However, it cannot be read and modified arbitrarily without distinction. The present invention adopts a user request plus permission control mode to realize the distribution of the required result data to different users in the engineering safety monitoring and management module.

Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art described in this application.

[0019] An engineering safety management information system covering unified GNSS calculation is provided. The system forms a unified entry point, unified calculation, online flow, and comprehensive application. The system includes a device access and management module, a data management and preprocessing module, a baseline calculation and quality assessment module, a data scheduling and access control module, and a comprehensive application module.

[0020] A unified entry point means that all monitoring data from all projects is reported to the data center through a single entry point; unified processing means that all data is processed through a unified platform and stored in a single location; online transfer means that the processing results are transferred between the project and the data center via the aforementioned unified platform both within the system and online; and integrated application means that interfaces are reserved for business systems to call the processing results from the aforementioned unified platform, realizing the integration of processing results with project safety monitoring business. The aforementioned unified platform is a comprehensive project safety management information system.

[0021] The device access and management module is used to establish a communication link with the base station through a wireless communication network, thereby realizing site access and online management, and data transmission control. This module uses wireless communication technology to connect with site equipment and integrates the communication module into the system to form a professional module.

One map displays the site connection status, using different colors to indicate different connection statuses: green for online, red for offline, and yellow for never connected, with statistics on measurement point data for each status. Another map displays the site data transmission status, using different colors to indicate different data transmission statuses: green for transmitting, red for transmitting (disconnected), and yellow for never transmitting, with statistics on measurement point data for each status. Finally, another map displays the calculation status, using different colors to indicate different current calculation statuses: green for successful calculation, red for calculation failure, and yellow for never calculated, with statistics on measurement point data for each status.

[0026] The site details section allows you to view basic information, real-time transmitted data, epoch statistics, solution information, and event logs.

[0027] The data management and preprocessing module acquires real-time data transmitted from monitoring equipment, preprocesses the data to prepare it for computation, and manages the preprocessed data uniformly. This module aims to provide a data stream interpretation unit, a quality assessment unit, a hierarchical monitoring unit, a data storage security control unit, a data retransmission unit, and a fast query unit.

[0028] The data stream interpretation unit converts satellite observation data streams into RINEX standard data format in real time during transmission and stores them for later use. The quality assessment unit adopts the QC data quality assessment system and uses a near real-time task scheduling method to organize and schedule the landing data for a specified duration, and to evaluate the main data quality indicators for each task period.

[0029] After processing a single numerical quality task executed by the data management and preprocessing module, the hierarchical monitoring unit performs data anomaly checks on the main quality indicators of constellation-level and even single-satellite-level data, conducts preliminary screening of dirty data, and removes abnormal datasets to improve the availability of subsequent algorithm solutions. Through comprehensive processing and evaluation of various indicators, it classifies their availability levels to clearly define the health status and availability level of data collection by the equipment deployed at the specified deformation points.

[0031] The baseline calculation and quality assessment module can convert preprocessed data into commonly used coordinate data or latitude, longitude, and elevation data, and evaluate the reliability of the calculation results. This module integrates a calculation module to support functions and services such as independent calculation of BeiDou data, real-time baseline calculation, baseline variable duration calculation, single baseline calculation, multi-baseline calculation, network adjustment calculation and task recalculation, calculation scheduling, reliability evaluation, and labeling.

[0032] BeiDou data standalone processing refers to processing BeiDou monitoring data separately; baseline real-time processing refers to processing monitoring data in real time during transmission; baseline variable duration processing allows users to define a specific time period for processing as needed; task recalculation involves reviewing previously processed data and recalculating it; processing scheduling requires scheduling processing data and resources when multiple data requests are made simultaneously to prevent congestion, and the processing module can be expanded to enhance computing power if necessary; the credibility evaluation refers to the reliability of the processing results, thereby enhancing the credibility of risk scenarios.

[0033] The data scheduling and access control module enables user access permission management and differentiated access permissions for monitoring data based on user level or user category, allowing for readability and editability. Because the monitoring data uses a unified entry point, unified processing, and unified storage management, different secondary units or departments need to obtain the required data from the data center. However, indiscriminate reading and modification are not permitted. This invention employs a user request plus access control model to distribute the required results data to different users within the engineering safety monitoring and management module.

[0034] The integrated application module enables deep integration of calculation results with engineering safety monitoring operations, allowing for regularity analysis of monitoring data, real-time diagnosis and monitoring of dam safety, and alarm and emergency handling for abnormal situations. The integrated application module includes a safety diagnosis unit and a result publishing and anomaly alarm unit. The safety diagnosis unit aims to analyze the regularity of the solution results by establishing a statistical model, diagnose the dam's safety status under the current condition, and predict the dam's safety status under a certain working condition in the future. The results publishing and anomaly alarm unit is used to publish the results of security diagnosis through the system's client terminal, while issuing alarms of the corresponding level for abnormal results and automatically pushing them to relevant personnel for emergency handling.

[0035] A method for engineering safety management encompassing unified GNSS data processing is disclosed. This method integrates and streamlines the entire business process of GNSS data acquisition, storage, processing, scheduling, and application. Simultaneously, based on engineering safety monitoring requirements, it uses an established statistical model to mine and analyze the patterns in the processing results, diagnoses the engineering safety status in real time, and classifies the engineering safety diagnosis results into normal, slightly abnormal, generally abnormal, and severely abnormal levels according to the "Guideline for Safety Evaluation of Hydropower Station Dam Operation" (DLT 5313). Corresponding measures are then taken for each level. Specifically, the method includes the following steps: S1. Data Acquisition: S2, Data Preprocessing and Storage: S3. Ephemeris data converted into coordinate data: S4. Evaluation of Solution Results: S5. The solution results are applied to engineering safety diagnosis.
