Description
Technical field
The invention belongs to weight measurement technical fields, and in particular to a kind of silo material weight based on distributed weighing node
Consumption metering system and method, the system and device measured more particularly, to the weight to material stored in large silo and
Measurement method.
Background technique
In grain and oil, chemical industry, food is all to carry out material storage, these silos using large silo in the industries such as feed
Interior, often dust is big, and requirement of explosion proof is high, and space is very big, stores material a few kiloton or even tens of thousands of tons.But there is presently no compared with
Good method carrys out the weight of the material stored in these silos of precise measurement, so that many business administrations be caused to be not good at, occurs
The problems such as material is lost, account not in order.Currently, the method for being used for large silo weight measurement, mostly uses and is arranged at the top of silo
Several observation panels, mode obtains the height of material at observation panel by hand, and is averaged, and calculates using certain, obtains institute
The volume and weight of storage material.When surface of material is uneven, often measurement error is larger for this method；Using sharp
Optical radar carries out revolving lattice scanning to surface of material, and carries out trigonometric function conversion, it is also possible to obtain the three-dimensional of material
Figure, but the silo in operation, often dust is big, causes laser ranging inaccurate；Microwave radar can be used for ranging, adopt
With rotary lattice scanning, the distance measurement result of surface of material is obtained, three-dimensionalreconstruction is carried out, to obtain volume and weight, still
Microwave radar locking time is slow, and the distance for surveying a point was needed up to 10 seconds, therefore single microwave radar generally requires 15
Minute or more could obtain a material 3D shape (such as in surface of material scan 100 points), in addition, high-precision micro-
Often price is higher for wave radar, but range accuracy is limited, and controls the mechanical structure that microwave radar carries out rotary scanning
It will also result in range error increase；Use microwave beam reflect etc. technologies, it may not be necessary to mechanical structure control microwave radar into
Row rotary scanning, but it is expensive using the equipment price of this technology at present, and precision is limited, general error is 3% or more.
In conclusion needing a kind of new system and method, accurate weight measurement is carried out to the material in large silo.

Preferably: when silo structure is more special, needing to add auxiliary device, so that the top stress surface of weighing node
Keep horizontal.
In general, through the invention it is contemplated above technical scheme is compared with the prior art, can obtain has as follows
Beneficial effect:
Weighting error is smaller, and error is no more than 1%；Weighed by distribution, each weight for being carried of weighing node compared with
It is small, 500 kilograms are not exceeded generally, are not exceeded 1 certainly, are avoided the need for the problem of large-scale weighing-appliance is set.It is practical
In, it is also difficult to which manufacture weighing is up to a few kiloton or even tens of thousands of tons of weighing device, even if manufacturing, it is also difficult to which investment is real
Border uses；For powdery or granular material, do not have to carry out overall weight measurement；Large silo material or deposit use
Distributed weighting manner, measured value and practical height of materials may not be linear relationship, but reality can be used in this method
It tests and the method for Optimization Solution, the accurate corresponding relationship for obtaining distributed weighing value and practical material total weight；For special knot
The silo of structure, can be weighed point with flexible arrangement, flexibly make experimentally to obtain data, then carry out analysis and data are quasi-
It closes, obtains accurate result；This system and method are not limited to silo, also can be applied to other kinds of large-scale accumulation
The three-dimensionalreconstruction of material and storage material, cubing, weight measurement, without the concern for the vertical frictional force pair of silo side wall
The influence of weight of material.
