大空间中火源的空间位置的定位，一直是火灾自动探测与自动扑救中的难点。研究了一种利用单一CCD摄像头进行火灾自动空间定位的方法。根据计算机视觉原理，利用固定在自动消防水炮末端的CCD摄像头随水炮旋转扫描时的角度、位移变化，将CCD摄像头在不同位置所拍摄的图像中火源图像坐标和火源的空间坐标建立联系，从而实现了火源空间位置的自动定位。

An automatic fire searching and suppression system with remote-controlled fire monitors for large spaces is developed. The fire searching method is realized based on computer vision theory via one CCD camera fixed at the end of a fire monitor chamber. While the fire monitor is pivoting, continuous images are taken from the CCD camera and transmitted into a computer. Then the images are processed with an image fire detection method to determine whether a fire occurs in the vision field. Once a fire is detected, it will be automatically located through an image processing algorithm. Displacement and pivot angle of the CCD camera in searching process are the essential parameters to calculate the space coordinates of a fire. When the coordinates of the fire are obtained, the fire monitor can be adjusted to the appropriate direction and elevation to spray according to water pressure.

The vibration of the charging belt in an electrostatic accelerator has intense influ-ences on the accelerator operation. A calculating model was set up in this paper to study the belt vibration. The results show that the belt tension, belt velocity and belt current all contribute to the belt vibration. There IS an optimal relationship among the three factors by which the belt would run most smoothly. There exists a minimum value of optimal tension for various belt velocities. The vibrating frequency of the is generally around several Hz.
