There may be several reasons why the parameters captured by an embedded development board in jitter may be shifted, and the following are some of the factors that may lead to parameter shifting:
1.**Mechanical Vibration**:
If the embedded development board is subjected to mechanical vibration, for example, from the movement of the device or vibration from the external environment, it may lead to the displacement or loosening of internal components, which may affect the sensor's accuracy.
2.**Electromagnetic Interference**:
Electromagnetic interference may come from other electronic devices or power supplies, affecting the stability of the internal circuitry of the development board and leading to shifts in parameter acquisition.
3.**Temperature changes**:
Changes in temperature may cause fluctuations in the performance of electronic components, and if the embedded development board is subjected to temperature during use, it may cause parameters to drift.
4.**Power supply instability**:
If the power supply of the embedded development board is unstable, it may cause the internal circuitry to work improperly, thus affecting the accuracy of parameter acquisition.
5.**Sensor quality and calibration**:
The quality and calibration level of the sensors used by the embedded development board may affect the accuracy of the parameters. Low quality sensors or sensors that are not properly calibrated may result in parameter shifts.
6.**Program Errors**:
There may be errors in the software program of the embedded development board, such as inaccuracies in the acquisition algorithms or problems with the processing of the sensor data, which may also lead to parameter offsets.
In order to solve the problem of parameter offset, the following methods can be considered:
1.**Reinforcement of mechanical structure**:
Ensure that the mechanical structure of the embedded development board is solid, and reduce the impact of mechanical vibration on the internal components.
2.**Use anti-interference measures**:
Take measures to prevent electromagnetic interference, such as the use of shielding materials or increase interference suppression circuitry.
3.**Temperature stabilization**:
Control the operating temperature range of the embedded development board to avoid parameter changes caused by temperature fluctuations.
4.**Ensure stable power supply**:
Ensure stable power supply for embedded development boards, use high-quality power adapters, and consider adding power filters.
5.**Use high-quality sensors**:
Select high-quality sensors and make sure they are properly calibrated to improve the accuracy of parameter acquisition.
6.**Check Programs and Algorithms**:
Review the software programs of the embedded development board to ensure that the acquisition algorithms and data processing processes are correct.
By considering the above factors and taking appropriate preventive and corrective measures, you can improve the accuracy of parameter acquisition of the embedded development board in jitter.
