Abstract

Community sports, school sports and home sports run through human lifelong sports. Community sports have a wide audience and can participate in sports activities. School sports are an important part of lifelong sports. Family sports are important for the development of children’s physical exercise Impact. The application of multi-sensor data fusion technology in various fields, of which the current research is more focused on the problem of synchronous data fusion, that is, it is assumed that each sensor measures the target synchronously and transmits the data to the fusion center synchronously. But often encountered in practice It is an asynchronous fusion problem. Based on the above background. The research content of this paper is the application of asynchronous multi-sensors in the fusion of school sports, home sports and community sports. In this paper, the problem of asynchronous multi-rate measurement processing in multi-sensor detection environment is studied. Under the condition that the fusion center filtering speed is slow and the sensor sampling rate is fast, one fusion cycle needs to process multiple asynchronous measurement data. The pseudo measurement method can make full use of multiple time series and multiple quantities of measurement information in a fusion cycle, and combine the model’s pre-push information at the fusion time to build a time-synchronized pseudo measurement. Through these methods, the asynchronous fusion problem is transformed into a mature solution. Fusion problem of simultaneous measurement. Finally, the experimental simulation shows that CR = 0.0801 < 0.11, so the judgment matrix has acceptable consistency. And the noise correlation processing can improve the tracking accuracy, but because the increase is small and the matrix inversion operation is increased, it is necessary to make a proper trade-off between accuracy and calculation amount when applying this method.
