为了研制适应矿井恶劣环境下跑车的速度传感器,分析了已有跑车速度检测方法存在问题。提出了双雷达多普勒检测方法,在挡车栏两侧分别检测跑车的速度,从而为跑车防护装置提供了一种全新的速度检测方案。
In order to develop the Speed Sensor of the mine car adapting to the harsh environment of the underground mine, the problems of the existing mine car speed detection are analyzed. Detection method of the Dual - Doppler radar has been proposed. The method can detect the speed of the mine car of both sides of the block fence, so as to the new speed detection scheme is provided for the protective device of the mine ear.
