The application discloses a bearing residual life interval prediction method and system, and the method comprises the following steps: collecting signal data of a bearing at time t, and predicting a life prediction value of the bearing at time t based on the signal data; predicting an upper limit of a residual life interval of the bearing at time t based on bearing life cycle data stored in a historical knowledge base and the life prediction value of the bearing at time t; predicting a lower limit of the residual life interval of the bearing at time t based on the life prediction value of the bearing at time t and complete life cycle data or error data based on signal data at time t and signal data at historical time; and determining the residual life interval of the bearing at time t based on the upper limit of the residual life interval of the bearing at time t and the lower limit of the residual life interval of the bearing at time t.

The invention discloses an integrated processing system for full life cycle review of a track signal system, and the system comprises a database platform which is used for carrying out the unified archiving and use management of data in output objects of all departments in a life cycle stage; the operation module is used for establishing a review form, designing internal and external review emphasized items, covering a complete life cycle of the item, reviewing an output object and obtaining review feature data; the test module is used for testing test data in output objects of all departments in the life cycle stage, archiving and analyzing obtained test results, and designing and reviewing test cases; and the statistical comparison module is used for counting the review feature data and the test result, and comparing the review feature data and comparing the review feature data with the test result. The invention further discloses an integrated processing method for full life cycle review of the track signal system. Defect prediction and prevention in the engineering development and implementation process are achieved.

Concrete can be one of the most durable building materials where consumption is projected to reach approximately 40 billion tons in 2017 alone. Despite this the testing of concrete at all stages of its life cycle is still in its infancy although testing for corrosion is well established. Further many of the tests today are time consuming, expensive, and provide results only after it has been poured and set. Accordingly, by exploiting self-contained wireless sensor devices, which are deployed with the wet concrete, the in-situ curing and maturity measurement data can be established and employed together with batch specific concrete data to provide rapid initial tests and evolving performance data regarding the concrete cure, performance, corrosion of concrete at different points in its life cycle. Such sensors remove subjectivity, allow for rapid assessment, are integrable to the construction process, and provide full life cycle assessment.
