The weighing system 200 includes at least one weighing device 201 for weighing the loading device 500 to obtain the loading weight of the loading device 500. A correction amount generating device 300 is provided in the flow meter 103. The correction amount generating device 300 includes at least one first data processing device 302. The first data processing device 302 generates a loading deviation amount based on the cumulative flow rate of the loading of the loading device 500 by the loading system 100 obtained by the flow meter 103 and the loading weight of the loading device 500 obtained by the weighing device 201.

[0165] In the above embodiment, preferably, the material production system 400 further includes a third data transmission device 403. The parameter acquisition device 402 transmits the material production parameters to the first data processing device 302 of the correction amount generating device 300 via the third data transmission device 403.

[0166] Preferably, the parameter acquisition device 402 transmits the material production parameters to the first data processing device 302 of the correction amount generating device 300 via the third data transmission device 403 and the first data transmission device 301.

[0167] In the bulk material metering system 1000 in the above embodiment, the third transmission channel 404 between the third data transmission device 403 and the first data transmission device 301 is a wireless transmission channel or a wired transmission channel.

[0168] For the bulk material metering system 1000 of each of the above embodiments, the data transmitted between each subsystem (loading system 100, weighing system 200, and / or material production system 400) can be transmitted to a cloud platform (equipped with a correction quantity generation device 300) outside the bulk material metering system 1000, and calibration correction parameters can be generated on the cloud platform and returned to the bulk material metering system.

[0169] For the bulk material metering system of at least one embodiment of the present disclosure, by means of a weighing device and an identification device, the deviation of each loading of the flowmeter is calculated, and the flowmeter is compensated by this deviation to maintain the accuracy of the flowmeter.

[0170] For the bulk material metering system of at least one embodiment of the present disclosure, by analyzing the deviation of each loading in association with a material production system (such as a cement production system), the influence of material production parameters on the deviation of the flowmeter is obtained, thereby achieving early compensation.

[0172] The above-mentioned early compensation can solve the problem of lag in weighing compensation and the problem of accuracy compensation that cannot be achieved by weighing compensation. For example, when the accuracy influencing factors of the flowmeter suddenly change, the bulk material metering system can only weigh the loading equipment after the loading is completed.

[0173] Through the above-mentioned early compensation, the accuracy deviation problem of the flowmeter caused by the sudden change of accuracy influencing factors can be solved.

[0174] For the bulk material metering system with an early compensation function of at least one embodiment of the present disclosure, during a loading process, if the influencing factors change, but weighing calibration has not been performed yet, through the influence of the above-mentioned influencing factors (material production parameters) on the measurement accuracy of the flowmeter during this loading process, early compensation can be achieved, thereby ensuring the measurement accuracy of the flowmeter during this loading process.
