摘要

对基于霍尔效应传感器的火箭滑橇速度测量系统的不确定度进行了评估。基于不确定度理论，从传感器安装距离、可重复位置和触发信号阈值对不确定度进行了评定，并计算了5m的安装距离，最大速度为1000m/s的测速系统的标准不确定度和复合不确定度表明，该系统的精度可达到$pL 2m/s。评价结果可为基于霍尔效应传感器的火箭滑橇测速系统的构建提供技术支持。

Evaluation of Uncertainty in Rocket Sled Velocity Measurement Based on Hall Effect Sensor

The uncertainty of rocket sled velocity measurement system based on Hall effect sensor was evaluated. Based on the uncertainty theory, the uncertainty is evaluated from the sensor installation distance, repeatable position and trigger signal threshold, and the installation distance of 5m is calculated, the standard uncertainty and composite uncertainty of the velocity measurement system with a maximum velocity of 1000m/s show that the precision of the system can reach $pL 2m/s. The evaluation results can provide technical support for the construction of rocket sled speed measurement system based on Hall effect sensor.
