Description
[technical field]
The present invention relates to volume volumetric measurement, particularly a kind of volume volume measuring method.
[background technology]
The most both at home and abroad for the measurement of volume bulk cargo level, this original method of artificial unwrapping wire is even used to survey
Material position, time-consuming, laborious, low precision, use electrometric method only more effective, to solid granule still to liquid, free fluid
Can not accomplish to measure the most accurately.Because the charge level of solid granule has not stationarity, gained reserves are incorrect, especially
It is that large-scale volume reserves degree of accuracy differs greatly especially, even up to tens tons, the difference of tens tons.As shown in figure, a,
Tri-kinds of charge level situations of b, c, the charge level caused due to the difference of discharge state is entirely different, level-sensing device measure three material bit lines with
Actual material position is all inaccurate.
Research to level-sensing device itself is to emerge in an endless stream, from artificial unwrapping wire to Weight type " stock rod ", the most relatively
For advanced non-contact infrared survey meter etc., production after using scene, can be maintained, simply can maintain the basis produced
On substantially increase the comfort level that show of material site, i.e. from manually to machinery, from machinery to contactless long-range control etc., but
It is to fail the most all the time to be solved for the accurate measurement of material position.
[summary of the invention]
For the shortcoming of prior art, it is an object of the invention to provide a kind of simple in construction, volume easy to use
Volume measuring method.
The technical solution used in the present invention is: a kind of volume volume measuring method, including level-sensing device and display terminal, its
It is characterised by: also include Date Conversion Unit；At least three level-sensing device is connected with display terminal by Date Conversion Unit.
Further, it is in one line that described three level-sensing devices prolong volume center line, and middle level-sensing device is in volume
Centre, keeps to the side volume inwall but does not contacts in two, both sides.
The beneficial effects of the present invention is: simple in construction, the level gauge metering method that easy to use, change is the most single, also
Without detecting instrument costly, can realize than expensive instrument more by the General Instrument combination of charge level point position can be recorded
Effect accurately.

[detailed description of the invention]
Present invention employs a kind of volume volume measuring method, including level-sensing device 1 and display terminal 3, it is characterised in that:
Also include Date Conversion Unit 2；At least three level-sensing device 1 is connected with display terminal 3 by Date Conversion Unit 2.
Further, it is in one line that described three level-sensing devices 1 prolong volume center line, and middle level-sensing device is in volume
Centre, keeps to the side volume inwall but does not contacts in two, both sides.
See accompanying drawing, under normal circumstances in Fig. 1 tri-kinds of charge level situations of a, b, c be usual charge level nothing more than basal conditions,
The situations such as chance volume inwall dross belong to phenomenon of the failure and should should be regarded as a different matter.
As in figure 2 it is shown, be added to three level-sensing devices by an original level-sensing device, it is in one line to prolong volume center line, in
Between level-sensing device in the central authorities of volume 5, keep to the side volume inwall but do not contact in two, both sides.
As it is shown in figure 1, three level-sensing devices are simultaneously connected with a Date Conversion Unit 2, this Date Conversion Unit 2 is for data
Distinguish and calculate.Display terminal 3 video data is fed back to again by this Date Conversion Unit 2.
Measure and perform:
Open for (1) three and measure, the most same to producing three data logging data converting units on cathetus.
(2) Date Conversion Unit counting process.As a example by Fig. 3, first minimum point feedback, i.e. the highest solid face of volume,
This volume solid face also may be regarded as entity level face, the position in its territory, face and the quantization in volume 5 and Media density contrast
Data have been stored in Date Conversion Unit 2, are i.e. converted directly into territory, face, the quantization number below this solid face of moment typing by a position
According to, the amount of being considered as 1.Secondly, remaining 2 feedbacks, on the basis of minimum point, another 2 points of virtual bracing wire, i.e. occur facing triangle, just
Depending on triangle portion amount 2 minimum point can not direct reaction, only just can be reflected the geometric form of its charge level by the line of 3
Shape, as Fig. 3 a amount 2 for conulite, b be inclined-plane cylinder, c be solid conical, i.e. by geometry principle at Date Conversion Unit
Effect under, amount 2 is converted directly into territory, face, the quantized data of this solid of moment typing, the amount of being considered as 2 by a position equally.
