Description
Technical field
The utility model relates to the technical field of rivers hydrologic survey, specifically is a kind of hydrometric cableway test system.
Background technology
Track cable flow-testing is a kind of flow measurement mode of China's original creation, is applicable to the cross-sectional area of the natural stream channel that gaging section changes easily and the measurement of mean flow rate, and other flow measurement method is not replaced at present.Hydrometric cableway test itself is the dynamic changing process of a complex space system, and like cableway spring, mechanical motion inertia, factors such as the variation of flow velocity all influence the precision of discharge measurement, and are stochastic variables.How setting up an Automatic Control flow measuring system, to improve the precision of hydrologic survey, is the technical barrier of this area
The utility model content
The technical matters that the utility model will solve provides a kind of simple in structure, hydrometric cableway test system that the hydrologic survey precision is higher.
In order to solve the problems of the technologies described above; The utility model provides a kind of hydrometric cableway test system; Comprise: CPU element, the analog-to-digital conversion module that is used to receive and change the fish lead stroke signal that links to each other with this CPU element, the limnimeter that is used to monitor SEA LEVEL VARIATION that links to each other with this analog-to-digital conversion module; Being used to of linking to each other with this analog-to-digital conversion module revised the declining compass of the bathymetric survey error of fish lead; Being used to of linking to each other with this analog-to-digital conversion module detected the current meter of the water surface, water-bed water velocity, the cableway motor-drive circuit that links to each other with said CPU element, control panel and demonstration printing interface, the PC that links to each other with said CPU element through the RS232 interface.
The technique scheme of the utility model is compared prior art and had the following advantages: the full-automatic track cable flow-testing system in the utility model has stronger compatibility; Be fit to the automatic or semi-automatic test in middle or small river course; Easy to operate performance is stable; The test precision is higher, has reduced operator's labour intensity and the working time effectively.
Description of drawings
For the content that makes the utility model is more clearly understood, below basis specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation, wherein
Fig. 1 is the knot block diagram of the hydrometric cableway test system among the embodiment.
Embodiment
See Fig. 1; The hydrometric cableway test system of present embodiment; Comprise: CPU element, the analog-to-digital conversion module that is used to receive and change the fish lead stroke signal that links to each other with this CPU element, the limnimeter that is used to monitor SEA LEVEL VARIATION that links to each other with this analog-to-digital conversion module; Being used to of linking to each other with this analog-to-digital conversion module revised the declining compass of the bathymetric survey error of fish lead; Being used to of linking to each other with this analog-to-digital conversion module detected the current meter of the water surface, water-bed water velocity, the cableway motor-drive circuit that links to each other with said CPU element, control panel and demonstration printing interface, the PC that links to each other with said CPU element through the RS232 interface.
CPU element adopts the AT89S8252 single-chip microcomputer.Since the big and computing more complicated of the data volume of river course test, and the memory span of single-chip microcomputer inside is limited.So increase external memory RAM 6116 and ROM6264; The input acquisition interface of external signal is to be core with analog-to-digital conversion module ADC0809, and cableway signal and water level signal are delivered to single-chip microcomputer after analog to digital conversion.
The flow velocity that analog-to-digital conversion module is sent the SEA LEVEL VARIATION signal and the cableway of water level gauge here simultaneously, drift angle, the water-bed signal of the water surface are sent to single-chip microcomputer after conversion.This analog to digital conversion interface has simple, reliable and stable, the anti-interference characteristics such as strong of circuit.
The suspension cable cableway is furnished with declining compass, is used for revising current and causes fish lead vertically not drop to the bottom and the bathymetric survey error that produces.Declining compass can be measured fish lead and receive water currents to depart from entopic angle, again according to the size of drift angle through tabling look-up or formula calculates and revises depth of water error.Manual measurement is that error is bigger with the size of eyes according to the scale estimation drift angle of declining compass.
The stroke signal of fish lead comprises the water signal of vertical moving when round stroke signal that moves of fish lead level and fish lead sound the depth of the water.
Obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not to be qualification to the embodiment of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation that these spirit that belong to the utility model are extended out or change still are among the protection domain of the utility model.
