The invention discloses an open channel section
water flow online measuring device and a measurement and control method. The device comprises a measuring supporting frame, a measuring rod
assembly is fixedly installed on the measuring supporting frame, a side rod
assembly communicates with a
signal processing control host 11, the measuring rod
assembly comprises a measuring rod 8 and a measuring rod driving mechanism, and a set of sensors are arranged on the side rod 8. The measuring rod driving mechanism comprises a measuring rod lifting motor 10, an output shaft of the measuring rod lifting motor 10 is fixedly connected with a coded disc 4 and a shaft angle
encoder 5, and the coded disc 4 is fixedly connected with the measuring rod 8. The technical problem to be solved by the invention is to provide the open channel section
water flow online
measurement device and the measurement and control method so as to solve the problems that the existing open channel flow measurement equipment realizes multi-vertical-line multi-measurement-point
water flow real-time online measurement according to relevant national standards, and the measurement is inaccurate under the conditions of
turbid water body, silted channel, sundries in the
water body and the like. The problem of real-time online flow measurement of the open channel can be effectively solved.
