Wherein, described first mode is with the discharging of volume mode, and the discharging speed of promptly described giving/measurer is constant.
Described second mode is for to weigh the mode discharging, promptly revises discharging speed to/measurer according to the minimizing degree of unit interval weight of material in the storehouse of weighing.
When adopting described volume mode discharging, open described reinforced valve, reinforced in the described storehouse of weighing by described former feed bin.
Adopt and describedly weigh the mode discharging time described reinforced valve closing.
Described giving/measurer adopts single screw rod or twin-screw discharging.
Beneficial effect of the present invention is, the weightless scale measuring accuracy of this Intelligent Dynamic height, operate steadily, adopt FPGA dynamic algorithm at a high speed, by AD sampling and proportional control feedback, make in the production run proportioning of material reach accurately and stable, the consistance of discharging and homogeneity have also had good assurance.Carry out real time data sampling in conjunction with the MATLAB Dynamic Simulation Technology by FPGA, after performance analysis, draw an experimental formula, be used for the setting of preset value, have real-time control and responding ability simultaneously, make weightless scale feed stability that great guarantee arranged.

[embodiment]
Below in conjunction with embodiment and with reference to accompanying drawing the present invention is further described.
As shown in Figure 1, the weightless scale of a kind of Intelligent Dynamic, at least comprise: former feed bin 100, the storehouse 200 and giving/measurer 300 of weighing, wherein, described former feed bin 100 and weighing is provided with reinforced valve 101 between the storehouse 200, described storehouse 200 outer setting of weighing have LOAD CELLS 201, and described giving/measurer 300 is provided with discharging opening 301, and the material in the described former feed bin 100 enters described discharging opening 301 outputs of 200 backs, storehouse by described giving/measurer 300 of weighing by reinforced valve 101.Weight of material in the storehouse 200 of weighing is lower than one to be preset down in limited time, reinforced valve 101 is opened, and is reinforced to the storehouse 200 of weighing by former feed bin 100, when the weight of material in the storehouse 200 of weighing is higher than a preset upper limit, reinforced valve 101 is closed, and former feed bin 100 stops to the storehouse 200 of weighing reinforced; Wherein, when described reinforced valve 101 was opened, described giving/measurer 300 adopted the first mode discharging, and when described reinforced valve 101 was closed, described giving/measurer 300 adopted the second mode discharging.
As shown in Figure 2, be structured flowchart of the present invention, the weightless scale of described Intelligent Dynamic also comprises control module, described control module comprises as lower module: intelligent weighing control instrument 10, servomotor controller 20, alternating current generator 30, motor encoder 40, AD conversion 50 and dynamic data analysis place 60.Intelligent weighing control instrument 10 is used for receiving in real time the weight information that comes from described LOAD CELLS 201, and weigh by calculating that the minimizing degree Δ d/ Δ t of time per unit weight of material adjusts servomotor controller 20 and alternating current generator 30 in the storehouse 200, give/discharging speed of measurer 300 with control.
In this embodiment, described first mode is with the discharging of volume mode, and the discharging speed of promptly described giving/measurer 300 is constant; Described second mode is for to weigh the mode discharging, promptly revises discharging speed to/measurer 300 according to the minimizing degree of unit interval weight of material in the storehouse 200 of weighing, and to adjust discharging speed, improves reinforced precision.Wherein, when adopting described volume mode discharging, open described reinforced valve 101, reinforced in the described storehouse 200 of weighing fast by described former feed bin 100; When adopting the second mode discharging, reinforced valve 101 is closed.
