Abstract

A wireless data transmission device oriented direct healthy factor construction method relates to the field of wireless data communication and achieves identification of a healthy situation of a wireless data transmission module. The invention includes a healthy factor construction method with power-up times being a variable and a healthy factor construction method with time being a variable. To a data transmission device, a most intuitive expression of a quantity having timing sequences is the power-up times, namely, a number sequence of a power-up test. A construction healthy factor can be used for representing a time of repeatable power-up operations during a usage process of a data transmission device. Because the data transmission device, in a certain time, is not used, missing data exists in the healthy factor construction method with the time being the variable, by means of statistical law, a wireless data transmission device oriented direct healthy factor can be generated and obtained and identification of the healthy situation of the wireless data transmission module is achieved. The invention is suitable for constructing the wireless data transmission device oriented direct healthy factor.

Description

technical field [0001] The invention relates to the field of wireless data communication. Background technique [0002] Failure prediction and health management (PHM) has gradually become an important research content in the field of complex system diagnosis and prediction. Especially with the rapid development of data acquisition and communication technology, the use of condition monitoring data for system degradation performance identification and health status prediction has become a hot method in the field of fault prediction and health management, that is, data-driven fault prediction and health management research. The data-driven fault prediction method has been widely concerned by experts at home and abroad, and its research objects have been extended from simple mechanical systems to batteries, aircraft subsystems, and satellite subsystems. However, data-driven methods are currently used for wireless data transmission. There are few reports on equipment trend forec...
