Micro-inertia measuring device based on ZigBee wireless singlechip

Abstract

The invention discloses a micro-inertia measuring device based on a ZigBee wireless singlechip, which at least comprises a six-axis micro-inertia sensor, a signal plate and a battery compartment. The six-axis micro-inertia sensor is used for collecting three-axis gyroscope signals and three-axis accelerometer signals according to a control instruction received from a processor module in the signal plate and outputting the collected three-axis gyroscope signals and the collected three-axis accelerometer signals to the processor module in the signal plate; the signal plate is used for controlling the six-axis micro-inertia sensor to collect the three-axis gyroscope signals and the three-axis accelerometer signals, controlling a three-axis magnetic field meter module in the signal plate to collect three-axis magnetic field meter signals, processing the collected data signals and carrying out strapdown analysis to obtain a gesture and a course transported to a movement carrier; and the battery compartment is used for placing a battery for supplying power for the device. The micro-inertia measuring device based on the ZigBee wireless singlechip has the advantages of high precision, low power consumption, small volume, light weight and good real-time and has the function of long-distance wireless transmission.
