| 摘要 |
The invention relates to hydrology and in particular to hydrometric works. Device for space-like measurement of velocity and direction of motion of water flow with respect to underwater apparatus that includes emitters and receivers of infrared radiation, electronic means for information processing. According to the invention it has six ultrasonic blocks: two emitters and four receivers that are installed in three normal to each other planes in such way that in horizontal and vertical planes trajectories of ultrasonic beams form squares and in each square in operation mode emitters and receivers are arranged with alternation. The device has control block, distribution block and block for data transfer, at that the first output of the control block is electrically connected to the first input of the block for information processing, second output of the control block is electrically connected to input of distribution block, and input of control block is electrically connected to the first output of the block for information processing. Distribution block is electrically connected to inputs of emitters outputs of which are connected to inputs of receivers with ultrasonic connection; those are electrically connected to input of the block of preliminary amplification output of which is electrically connected to the second input of the block for information processing. Block for information processing is electrically connected to the indication block, block for registration and storage of information and block of data transfer. The invention makes it possible to obtain increase of accuracy of spatial measurement of velocity and direction of motion of water flow with respect to underwater apparatus. |
