Abstract

The invention discloses a sensor sampling method and a related device. The sampling method includes: setting a common sampling period for a plurality of sensing modules, each sensing module includes a plurality of sensors, and the sampling period meets the requirements of each sensor. Sampling specification; at least divide the confidence time of the data generated by each sensor from the sampling period as the update interval, and the confidence time of the collected data as the collection interval; detect the operating status of the sensors in each sensing module in the sampling period; If the running state is in the state of updating data in the update interval, the operation of collecting the data generated by the sensor is completed for each sensor module respectively by the end of the collection interval. The above method divides the sampling period into regions by setting a common sampling period, determines the operating state of the sensor in a specific region, and determines the timing of synchronous data collection for multiple sensors according to the operating state, which can ensure that the collected data is Synchronized and aligned.

Description

technical field [0001] Embodiments of the present invention relate to a sensor signal detection technology, and in particular, to a sensor sampling method and a related device. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, the application of multi-sensor systems including multiple sensor modules in modern life is becoming more and more common. [0003] However, in view of the large variety of different types of sensors in the sensing module (mainly reflected in the difference in sampling frequency), and for the same type of sensor, there is also a large difference between the various sensors. Individual differences (mainly reflected in the differences in the data update cycle of each sensor), when using a multi-sensor system for data collection, it is difficult to collect data generated by multiple sensors synchronously. The data of all sensors in the sensor system can be collected synchronousl...
