Embodiment

[0019] An on-board database for a PHM system provided by an embodiment of the present invention, wherein the on-board database is a physical location integrated within the health-managed system rather than connected to an external or cloud database, such as figure 1 shown, including: transceiver, onboard database controller, memory, where:

[0020] The transceiver is used to convert the logical data information obtained from the onboard database controller into a physical level and send it to the outside world, and convert the data information received from the outside world from the form of physical level to be read by the onboard database controller logical data information;

[0021] The on-board database controller is used to set the path of data interaction with the outside world and the data update cycle; the memory is used to store the system information, historical data and knowledge base data of the PHM system. The memory in this embodiment, such as figure 2 As show...

Abstract

The invention discloses an onboard database for a PHM system. The onboard database comprises a transceiver, an onboard database controller and a memory, the transceiver is used for converting logic data information obtained from the onboard database controller into a physical level and sending the physical level to the outside, and converting data information received from the outside into logic data information which can be read by the onboard database controller from a physical level form; the onboard database controller is used for setting a path for interacting with external data and a data updating period; and the memory is used for storing system information, historical data and knowledge base data of the PHM system. The onboard database highly adapts to the storage structure of thePHM system, data storage is orderly, data is not prone to mutual interference, dislocation and loss, management and calling are convenient, real-time communication with an external unit is achieved, data updating of the onboard database is facilitated, version updating of the PHM system is facilitated, and the function of the PHM system is improved.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to an onboard database used in a PHM system. Background technique [0002] PHM (Prognostics and Health Management, failure prediction and health management) system is a data-driven health management system, so data storage, exchange performance, data security and data maintenance management are very important, so the onboard information storage of PHM system is very important for PHM system Significantly, the storage unit of the existing PHM system has a simple structure, insufficient functions, low security level, and imperfect development, which cannot meet the structural security requirements of the PHM system for data storage. Contents of the invention [0003] Therefore, the on-board database used in the PHM system provided by the present invention overcomes the defects of simple structure, insufficient function and low security level of the database storage unit in the pri...
