Finally, based on the analysis of the experiment results, an improved scheme is put forward, that is, the application of the external temperature sensor DS18B20, which avoids the error caused by low precision of the internal sensor and interference and improves system output frequency to some degree.
This paper presents a robot autonomous calibration approach,the kinematics equations are built through the probe fixed in the endeffector contacting the constraint planes in the workspace,The robot internal sensor measurements are recorded for kinematics calibration while the tippoint of the probe is in contact with the constraint planes,the locations of the constraint planes are not necessarily known exactly.
Using internal sensors of vehicle instead of inertia sensor to get orientation/velocity information, the system/observation equations of vehicular dead reckoning(DR) navigation system are established. The current statistics model is introduced to describe the maneuvering vehicle kinematics, and then the navigation algorithm based on adaptive Kalman filter for DR system without gyroscope is proposed.
And have a deep research on the main part of printer(include typing head, main board, the package of the power, inside sensorsystem) and the structure, material, operation principle of combining relevant parts. It established a foundation for after improving of printer's performance.
The coaxial configuration of gas-insulated substations is of great advantages transmitting the electromagnetic wave excitated by partial discharge and of great advantages of partial discharge detection. Based the characteristics of configuration of GIS and PD signals inside, the authors design a disc coupler and a loop coupler for continuous monitoring of partial discharge in GIS, and analyze the sensor's characteristics theoretically.
The prestressed effect tested by the sensor in the model was compared with that of calculated by the finite element method,which can be used to find out if the stress state in the anchorage zone attained the expected design requirement after tendons stressed. Consequently,the reliability of procedure could be verified.
