This invention provides a
data acquisition and detection device and method for underground
sewage pipes connected to rainwater pipes. First, after the detection device enters the
pipe, under the support of the power
system and the action of
sewage flow, the
image system acquires
pipe images, while the
sensing system collects
water quality chemical parameter data. Second, the GPS in the
transmission system records the path and transmits the collected information to the ground terminal. Finally, the
system automatically plots the path-
water quality chemical parameter variation curve and the derivative variation curve of
water quality chemical parameters with path s. Based on the abrupt changes in the water quality chemical parameter derivative variation curve with path s, combined with the image information, a comprehensive analysis is performed to determine whether there is a mixed or incorrect connection in the
pipe. This acquisition and detection device has the advantages of comprehensiveness, high efficiency, ease of operation, low cost, and
mass production capability, and has broad application prospects.
