Embodiment 1

[0034] A database fusion relational system, such as figure 1 As shown, it includes several sensors, real-time database, historical database, fusion management module and filter tracking. The fusion management module includes calibration module, correlation module, identification module and estimation module, such as image 3 As shown, real-time databases are used for data entry and maintenance, real-time data updates, communication with historians, and communication with applications such as Figure 4 As shown, the real-time database includes a data backup system and a data recovery system. The data backup system is used for the cloud database to store data information in the real-time database in the cloud, and the data recovery system is used for the real-time database to read the data information in the cloud database.

[0035] The data backup system is completed according to the following steps: the cloud database is sent to the real-time database according to the backup s...

Embodiment 2

[0041] As the second embodiment of the present invention, the fusion method of the database fusion association system includes as follows:

[0042] S1: When the sensor obtains the target information, it first stores the target information in the real-time database and is controlled by the fusion management module;

[0043] S2: Read data from the real-time database, and perform trajectory correlation and filter tracking;

[0044] S3: Manage the work of the sensor according to the fusion results and observation values, and store the observation values ​​and filtering results in the real-time database for trajectory correlation and filtering at the next moment;

[0045] S4: During the fusion process, the data in the real-time database is periodically transferred and stored in the historical database.

[0046] The database fusion association system of this embodiment starts from the requirements of data fusion on the database, establishes a database model supporting the data fusi...

Embodiment 3

[0048] As the third embodiment of the present invention, the filter tracking adopts the secondary filtering algorithm to detect and track the target, and the secondary filtering algorithm is:

[0049] Assume and is the optimal estimate at time k, and is the predicted value of the best estimate, P(kk), P 1 (kk) and P 2 (kk) is the corresponding error covariance gap matrix, P(kk-1), P 1 (kk-1) and P 2 (kk-1) is the corresponding error covariance prediction matrix;

[0050]

[0051] in:

[0052]

[0053]

[0054] A global optimal estimate is obtained by synthesizing two local optimal estimates, and the second filtering algorithm is used to track the target, thus greatly improving the tracking accuracy.

[0055] The database fusion and association system of the present invention combines the fusion model and the database into a unified whole, designs the database from top to bottom, and realizes an overall optimized database strategy, which has great advanta...

Abstract

The invention relates to the technical field of data processing, in particular to a database fusion association system, which comprises a plurality of sensors, a real-time database, a historical database, a fusion management module and a filtering tracking module; the fusion management module comprises a calibration module, a correlation module, an identification module and an estimation module; the real-time database is used for data entry and maintenance, real-time data updating, historical database communication and application program communication. The fusion model and the database are combined into a unified whole, the database is designed from top to bottom, an integrally optimized database strategy is achieved, great superiority is achieved, the performance and the reliability of afusion system can be guaranteed, the working efficiency of the database can be greatly improved, and starting from the requirement of data fusion for the database, a database model supporting a datafusion algorithm is established, and a special database of a data fusion system is developed on the basis of the model, so that the real-time performance is met, and the storage amount of data in a memory is reduced.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a database fusion and association system. Background technique [0002] With the continuous development of science and technology, the amount of information that people obtain is increasing, and at the same time, the forms of information are also tending to be diverse. In the multi-sensor data fusion system, the amount of information obtained is also large and in various forms. When performing data fusion, it is necessary to access these relevant supporting data, and the storage and access forms of these data will directly affect the working performance of the data fusion system. At this time, the traditional data files can no longer meet the needs of data fusion in terms of data storage and data update. Contents of the invention [0003] The purpose of the present invention is to provide a database fusion and association system to solve some or some defects in the ab...
