The invention relates to the technical field of sensor data processing, in particular to a batching method and device of sensor data, electronic equipment and a storage medium. The batching method ofthe sensor data includes the steps that the sensor data is continuously obtained within a first time at a first sampling rate; the obtained current sensor data is subjected to data compression to obtain a first data column and a bit indication column, and the first data column and the bit indication column are stored in a first memory; all packed data in the first data column is sequentially subjected to data reconstruction according to the bit indication column, and the reconstructed data is sequentially transmitted to an application processor. According to the batching method of the sensor data, firstly sensor data columns composed of multiple data samples are compressed and then cached, the compression state of the data is indicated through the bit indication data column, data construction is promoted, the constraint condition of the memory is relieved on the basis of reducing electric energy consumption, data displacement is not needed, flag bits do not need to be set, and the processing speed is increased.
Description
technical field [0001] The invention relates to the technical field of sensor data processing, in particular to a batch processing method and device for sensor data, electronic equipment and a storage medium. Background technique [0002] Recently, portable electronic devices with powerful MEMS (micro-electro-mechanical systems) sensors and high-speed processors may provide navigation functions. This method relies on MEMS sensors, such as: accelerometers, gyroscopic sensors, magnetic sensors, or a combination of sensors that can track usage or vehicles by continuously estimating displacement from a specified location. Currently, sensor processors are configured to acquire and transmit sensor data using less power than the main application processor and at a sampling rate. There are two ways to process data from sensors. First, the sensor processor can continuously process data in a streaming fashion within a time window. Second, the sensor processor can process data in ba...
