Problems solved by technology
However, single-sensor attitude detection is susceptible to inertial device drift and cumulative errors, resulting in decreased measurement accuracy
In addition, if multiple sensors such as independent accelerometers and gyroscopes are used for attitude detection, there are disadvantages such as large space occupied by multiple chips, large inter-axis error of attitude data, and low data fusion accuracy.

Embodiment Construction
[0015] The program is written in the PC through software, and the program displays the acceleration data collected by the MPU9250 attitude sensor through the LCD screen, and then makes the geometric carrier change irregularly, and the motion trajectory curve of the carrier can be smoothed through the Kalman filter. Observe whether the data on the LCD screen changes with the movement of the sensor. If the displayed data changes with the movement of the sensor, it means that the MPU9250 can be normally connected to the MCU control module and can work normally.
[0016] After completing the above MPU9250 verification, further verify whether the RGB light-emitting diodes can operate normally. Each pin of the six three-color light-emitting diodes is connected to a 1K current-limiting resistor, and is connected to the pin of the single-chip microcomputer control module through the current-limiting resistor. Each light-emitting diode has 4 pins, one pin is the anode, and 3 pins are ...

The invention relates to a color-changing display device for displaying the motion posture of an object according to the acceleration of the object, and belongs to the technical field of detection. The structure of the device is mainly composed of a single-chip microcomputer control module (1), an attitude detection sensor module (2), a liquid crystal display module (3), a geometric carrier comprising a light emitting diode and a sensor (4), and a power supply module (5). According to the design of the device, a single-chip microcomputer serves as a control core, the motion posture of an object is checked through a sensor, posture information such as the acceleration of the object is obtained, and data are transmitted to the single-chip microcomputer after processing. After the processing of the single-chip microcomputer system, the control diode displays different colors related to the magnitude and direction of the motion acceleration of the carrier of the sensor. And meanwhile, information such as acceleration is displayed on the display screen in real time. Characters or monochromatic images of various fonts can be displayed through the display screen. The single-chip microcomputer can display images and characters on a screen by controlling the 74HC573 chip to scan in rows and columns. The practical significance of the device is achieved.
Description
technical field [0001] The device of the present invention is a color-changing display device that displays the motion posture of the object according to the acceleration of the object. Specifically, it uses a multi-axis sensor to collect motion posture information, and performs serial communication and data processing with a single-chip microcomputer control to display in real time, and can be displayed through RGB A display device in which the color of a light-emitting diode changes to show the direction of motion of an object. It belongs to the technical field of detection. Background technique [0002] With the continuous development of science and technology, the precision requirements for motion control are also increasing. Motion control is mainly to obtain attitude information through object attitude detection, and object attitude detection has also become a prerequisite for obtaining attitude information and realizing precise motion control. The design of the accel...
