Embodiment Construction
[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0056] The embodiments of the present invention are aimed at a scenario where physiological signals with stable changes are collected for a long time and the collected signals are required to be transmitted within a short period of time. Long-time collection, that is, a large amount of data, if all the data is transmitted, the transmission time will exceed the expected time. The change is stable, that is, within a period of time, the fluctuation of the sampling val...

The invention provides a physiological signal compression transmission and reconstruction method and apparatus. The method includes the following steps: receiving M sampling data after downsampling N to-be-transmitted data, separately setting confidence for the M sampling data, wherein N is greater than M, and the confidence of current sampling data reduces along with the increase of deviation of the current sampling data from the average [mu]T of the M sampling data; on the basis of the confidence of each sampling data, separately correcting each sampling data, obtaining the corrected sampling data, wherein the numerical values of the corrected sampling data is in positive correlation with the confidence of the current sampling data; and based on preset interpolation algorithm, conducting interpolation reconstruction on the corrected sampling data, again acquiring the N sampling data. The method can effectively reduce data transmission time, also increases the accuracy of signal reconstruction, and addresses the problems of complex methods and weak universality in the compression transmission of specific signals and introduction of abnormality and interference to signal analysis in the process of signal reconstruction.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a physiological signal compression transmission and reconstruction method and device. Background technique [0002] In the application of mobile health, it is often necessary to collect long-term physiological signals through the sensor terminal and send them to the mobile phone client through Bluetooth Low Energy (BLE). For example, in a health application that monitors sleep through heart rate, it takes 150 seconds to collect heart rate data for about 8 hours a night and transmit it in the notification mode of BLE. There is still a clear gap between this and the best experience for users. Therefore, compressing data and increasing the transmission rate of these physiological data is very important for enhancing the user experience of the entire system. Among them, notification mode transmission is a common data transmission method used by low-power Bluetooth for commun...
