Data acquisition unit workflow diagram of the present utility model, as shown in Figure 2.
The course of work of the present utility model comprises the following steps:
The master controller integral and calculating is based on definition:
Model belt material measurement plane coordinate system XOY, take the belt-conveying direction as the χ axle, the whole piece material is cut into N segment (N is enough large), and the scope of material is made as χ
1≤ χ≤χ
NWith the plane vertical with the χ axle, material is thinly sliced, material just has been divided into " figure of minute widths ".
Cutting material on the point of coordinate χ, establishing function S (χ) is function about χ for the sectional area on the point of coordinate χ." area of tangent plane " is S (χ) in the side of a χ, is S (χ+Δ χ) in point (χ+Δ χ) side, and both are some difference a little.This is that when beginning to increase Δ χ from a χ, the increment of volume is that the folded thickness of respective cross-section separately of a χ and point (χ+Δ χ) is the small part of Δ χ.If cut thickness very thin very thin, the shape in cross section, left and right is just almost identical, and it is almost equal that their area also becomes, and is also that thickness is thinner, and the cross section of left and right is just more consistent.As shown in Figure 4.
Namely when Δ χ → 0, area of section S (χ+Δ χ) → S (χ).
And area of section S (χ) can consist of according to the bottom data of belt material upper surface scan-data and initial acquisition, as shown in Fig. 3 c.Therefore area of section S (χ) can easily try to achieve.
If the travelling speed v(of belt is constant at the uniform velocity the time) measure gained by radar meter, time interval Δ t, enough little just can the making of Δ t obtained high sweep frequency, and thin slice is thinner, and area of section S (χ) is more accurate.The intelligent data processor calculates belt translation distance Δ χ=v Δ t according to the belt travelling speed v binding time interval of delta t that radar records, and the cumulative volume of tested material is V
Always:
System Working Principle is: by laser scanner, radar meter and intelligent data processor are installed above belt.The operation of belt triggers the beginning of belt material dynamic monitoring system.Before beginning to measure, input coal numbering, measure belt shape correction data on the intelligent data processor.Operation along with belt, radar meter is measured the belt travelling speed, the speed combination Time Calculation belt translation distance that the intelligent data processor records according to radar meter, material upper surface on the laser scanner scans belt is triggered at the interval at a certain distance, itself and the bottom data formation cross sections of initial acquisition.Each section carries out integral and calculating in real time on the belt working direction like this, just obtains the real-time cumulative volume of transported material on belt.The intelligent data processor uploads to master controller with belt material data and the stock number that records by network.When belt is out of service, belt material dynamic monitoring system autoshutdown.
System not only can carry out online cubing to material, and more mass measurement is in real time online demarcated by sampling and obtained material density, thereby calculates and demonstrate instantaneous delivery and the integrated flux of material, calculates the gross mass of belt-conveying material.
Above embodiment only is used for explanation the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that do not break away from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be by the claim limit.
