1. A data collection device, comprising a logic circuitry, the logic circuitry comprising:
a timer, configured to generate timestamp data;
a control module, being a dedicated logic circuit independent of a multi-functional control unit, configured to, in response to receiving an interrupt signal of a Micro-Electro-Mechanical system (MEMS) sensor or a trigger signal of the timer, generate a data obtaining command and obtain the timestamp data from the timer for specifying a time at which the MEMS data is obtained;
a communication module, configured to, in response to the data obtaining command, obtain MEMS data from the MEMS sensor;
a time offset register, configured to store a pre-set time offset which is an empirical value with respect to the MEMS sensor; and
a packing module, configured to read the time offset from the time offset register, correct the timestamp data using the time offset, and pack the MEMS data and the corrected timestamp data into a data packet in which the MEMS data is associated with the corrected timestamp data which specifies the time at which the MEMS data is obtained.
