Problems solved by technology

This method requires a lot of manpower, and the measurement efficiency is low; especially when it comes to multi-parameter measurement, such as simultaneous measurement of terrain flow velocity, it is also necessary to continuously switch and install working equipment during the above measurement process, which is very cumbersome

Embodiment 1

[0049] Embodiment 1 provides a kind of river engineering model multi-parameter measuring device, see figure 1 , including: two parallel rails 1 arranged on both sides of the river channel of the river engineering model, and a measurement platform 2 erected on the two rails; a number of attribute signs are installed along the two rails 1, and the The attribute identification contains the attribute information corresponding to the section, and the attribute information includes the sequence number of the section; the first sliding device 3 and the second sliding device 4 are respectively installed on the front and rear sides of the bridge body of the measurement platform 2, and the Measuring equipment is mounted on the first sliding device 3 and the second sliding device 4 (the two sliding devices can carry different measuring equipment, such as a topography instrument and a multi-channel flow velocity measuring instrument), and the first sliding device 3 and the The second slid...

Embodiment 2

[0053] Embodiment 2 is further optimized on the basis of Embodiment 1, and the attribute information further includes: an extension number. Two fields are used in the attribute information to respectively store the sequence number of the section and the extension number.

[0054] The expansion number of the existing basic section is set to 0; when adding a temporary engineering section between the first existing basic section and the second existing basic section, the section sequence number of the temporary engineering section is set to be the same as the first existing basic section. The section sequence number of an existing basic section is the same, and the extension number of the temporary engineering section is set sequentially according to its sequence in the temporary engineering section between the first existing basic section and the second existing section. A numerical value from 1 to 15; wherein, the section sequence number of the second existing basic section is ...

Embodiment 3

[0057] Embodiment 3 is further optimized on the basis of Embodiment 1 or Embodiment 2, and the attribute information further includes: the attribute value of the distance between sections.

[0058] In the direction along the river, the distance between the two measuring devices carried on the first sliding device and the second sliding device is recorded as the first distance; in the direction along the river, the distance between the current section and the next section is The distance between two endpoints corresponding to the same side of the river course is recorded as the second distance; among them, the section sequence number of the next section is the section sequence number of the current section plus one, and both the current section and the next section can be existing basic sections Or a temporary engineering section; if the second distance is greater than the first distance, the section spacing attribute value corresponding to the current section is set to the firs...

Abstract

The invention belongs to the technical field of automatic control in river engineering model tests, and discloses a river engineering model multi-parameter measuring device and a walking control method thereof; it includes two parallel tracks arranged on both sides of the river engineering model channel, and erected on the two rails There are a number of attribute identifications installed along the two tracks, which contain the attribute information corresponding to the section, and the attribute information includes the sequence number of the section; sliding devices are installed on the front and rear sides of the bridge body of the measurement platform , the sliding device is equipped with measuring equipment, which is used to slide in the direction of the section; the left and right ends of the bridge body of the measuring platform are respectively equipped with a walking mechanism, which is used to move back and forth along the river channel on the two tracks and read the properties Marking; a control unit is installed on the measuring platform to control the movement of the sliding device and the traveling mechanism; the section-by-section walking method is adopted. The invention has the advantages of high practicability, convenient operation, low cost and reliable operation.

Description

technical field [0001] The invention relates to the technical field of automatic control in river engineering model tests, in particular to a river engineering model multi-parameter measuring device and a walking control method thereof. Background technique [0002] In fluid model tests such as hydraulic engineering, river engineering and harbor engineering, especially in large-scale river engineering model tests, it is necessary to measure various test parameters on possibly thousands of measurement sections in the entire watershed. In the river engineering model test, the parameter measurement of the specified batch sections within the measurement range requires the measurement platform to be equipped with measuring instruments, which are sequentially positioned at each target section, so as to carry out the measurement. [0003] At present, the mainstream method of positioning the measurement platform to the cross-section still relies on manual work. The surveyors measur...
