Then, when the material liquid is transferred to the feeding injection solenoid valve, the control terminal may, but is not limited to, control the injection solenoid valve for compressed air or compressed steam to switch from a closed state to an open state, so as to input the compressed air or compressed steam to the nozzle of the feeding injection solenoid valve and perform mixing and atomizing treatment with the material liquid, and inject the atomized material liquid mixture onto the material in the feeding machine, thereby completing the feeding of the material.

A schematic structural diagram of a charging pipe system according to an embodiment of the present application may be provided with reference to fig. 2. As shown in fig. 2, the feeding pipeline system may include a feeding tank, a gear pump, a first mass flow meter, a second mass flow meter, a feeding injection solenoid valve and a feeding machine which are connected in sequence through a plurality of feeding pipelines, the feeding tank is controllable by the control terminal to output the material liquid to the gear pump, and the gear pump is controlled to output the material liquid to the feeding injection solenoid valve along the pipeline according to the specified rotating speed, and then the feeding injection solenoid valve is controllable to inject the material liquid to the material which is placed in the feeding machine, so as to complete the feeding of the material. When the feed liquid passes through the feeding pipeline where the first mass flow meter is positioned in the transmission process of the feed liquid, the first mass flow meter can collect the cumulative amount of the feed liquid passing through the feeding pipeline; and when the material passes through the feeding pipeline where the second mass flow meter is located, the second mass flow meter can collect the material liquid cumulant passing through the feeding pipeline, and the whole feeding process can be monitored in real time according to the material liquid cumulant collected by the first mass flow meter and the material liquid cumulant collected by the second mass flow meter.

Specifically, in the process of feeding real-time monitoring the feeding pipeline system, the control terminal can control the feeding tank to output the material liquid with a preset mass to the gear pump from the bottom along the feeding pipeline, and control the gear pump to keep a first rotation speed corresponding to the preset mass to output the material liquid to the feeding injection solenoid valve along the feeding pipeline, wherein the preset mass can be determined according to the mass of the material to be fed and the feeding requirement (i.e. can be understood as a feeding proportion), for example, but not limited to, the preset mass can be determined according to the product of the mass of the material to be fed and the feeding requirement, and of course, the preset mass can also be a mass set by the control terminal in a default manner, which is not limited in the embodiment of the present application. It is understood that the preset mass may also be linearly proportional to the corresponding first rotation speed, and the corresponding first rotation speed may be calculated based on the linear proportion after the preset mass is determined according to the mass of the material to be charged and the charging requirement, but the first rotation speed may also be an initial rotation speed set by the control terminal by default, and is not limited in the embodiment of the present application.

It should be noted that, control terminal is in the in-process that the feed liquid of quality will be predetermine along the charging pipeline output to the gear pump from the bottom in the control feeding tank, still can synchronous control set up the conveyer belt in feeder top will treat reinforced material transmission to the feeder in to the feed liquid that will come through the charging pipeline transmission by reinforced injection solenoid valve sprays to the material in the feeder on, and then realizes reinforced synchronism.

Specifically, in the process of outputting the feed liquid to the feeding injection solenoid valve along the feeding pipeline by the gear pump at the first rotation speed, the control terminal may obtain, according to a preset time interval, the cumulative amount of the feed liquid passing through the feeding pipeline where the first mass flow meter is located and the cumulative amount of the feed liquid passing through the feeding pipeline where the second mass flow meter is located, where the cumulative amount of the feed liquid may be directly obtained by the mass flow meter, or may be calculated from the unit flow rate of the feed liquid collected by the mass flow meter and the preset time interval, which is not limited in this embodiment of the present application.

Further, after collecting the first feed liquid cumulant and the second feed liquid cumulant in the same time interval, the control terminal may, but is not limited to, substitute the first feed liquid cumulant and the second feed liquid cumulant into a preset cumulant deviation value calculation formula to obtain the cumulant deviation value of the first mass flow meter and the second mass flow meter in the same time interval, where the preset cumulant deviation value calculation formula may be represented as follows:

in the above formula, the first and second carbon atoms are,

accumulated deviation value which may correspond to the i-th time interval>

Can correspond to the accumulated amount of the feed liquid collected by the first mass flow meter in the ith time interval, and the accumulated amount of the feed liquid collected by the first mass flow meter is collected by the first mass flow meter in the ith time interval>

Can correspond to the accumulated amount of the feed liquid collected by the second mass flow meter in the ith time interval, and the accumulated amount of the feed liquid is collected by the second mass flow meter in the ith time interval>

Which may correspond to a fixed difference in the cumulative amount of the first mass flow meter and the second mass flow meter during the charging process, which may be, but is not limited to being, taken through testing prior to the charging process.

It is understood that the fixed difference between the cumulative amounts of the feed liquid collected by the first mass flow meter and the cumulative amount of the feed liquid collected by the second mass flow meter in the preset time interval can be the fixed difference between the cumulative amounts of the feed liquid collected by the first mass flow meter and the cumulative amount of the feed liquid collected by the second mass flow meter before feeding.

And 106, when the cumulant deviation value is detected to exceed the preset deviation value interval, sending first early warning information, and acquiring the cumulant of the material input to the feeder based on the electronic belt scale.

Specifically, after the accumulated quantity deviation values of the first mass flowmeter and the second mass flowmeter in the same time interval are calculated, the control terminal may further determine whether the accumulated quantity deviation values of the first mass flowmeter and the second mass flowmeter in the same time interval exceed a preset deviation value interval, where the preset deviation value interval may be set to be 0 to 0.3, and possibly, when the accumulated quantity deviation value is detected to exceed the preset deviation value interval, it is indicated that the accumulated quantity deviation value exceeds an allowable range of an error rate, at this time, prompt warning information for indicating that the error exceeds the range is sent out, so as to prompt a worker that an error exists between the first mass flowmeter and the second mass flowmeter, and the first mass flowmeter and the second mass flowmeter need to be checked regularly.

Further, after the control terminal sends out the first early warning information for prompting, the control terminal can also acquire the accumulated amount of the materials which are collected by the electronic belt scale and input into the feeding machine, and the electronic belt scale can be arranged on the conveying belt so as to detect and record the accumulated amount of the materials output by the conveying belt in real time.

As an option of the embodiment of the application, when it is detected that the cumulant deviation value exceeds the preset deviation value interval, the method sends out first early warning information, and after acquiring the cumulant of the material input to the feeder based on the electronic belt scale, the method further includes:

In the embodiment of the application, the rotating speed of the gear pump can be adjusted according to the feeding amount calculated in real time, so that the feeding can be automatically controlled by adjusting the transmission rate of the feed liquid.

Specifically, the control terminal may not be limited to obtain the first feeding amount within the preset time interval according to the ratio of the first feed liquid accumulation amount to the material accumulation amount, and determine whether the first feeding amount is within the preset feeding amount interval. Possibly, when the first feeding amount is detected not to be in the preset feeding amount interval, the current feeding rate is indicated to be not meeting the requirement, and then an ideal feed liquid flow can be calculated by combining the preset feeding amount interval and the material accumulation amount, wherein the ideal feed liquid flow can be calculated by multiplying the intermediate value of the preset feeding amount interval by the material accumulation amount and dividing the product by the preset time interval.

Further, after the ideal flow rate of the feed liquid is calculated, a second rotating speed corresponding to the flow rate of the feed liquid can be inquired in a preset flow rate-rotating speed list, and the gear pump is synchronously controlled to output the feed liquid according to the second rotating speed.

It should be noted that, in the embodiment of the present application, data collected by the first mass flow meter is selected to control the feeding pipe system, and at this time, data collected by the second mass flow meter is used as a reference data volume.

As another optional option of the embodiment of the present application, when it is detected that the accumulated amount deviation value exceeds the preset deviation value interval, the method further includes, after the first warning information is sent and the accumulated amount of the material input to the feeding machine is obtained based on the electronic belt scale, further including:

Specifically, after the first early warning information for prompting is sent out, the control terminal may further perform integration processing on the first material liquid cumulative quantity in combination with the time intervals, and generate an instantaneous flow rate curve from each time interval and an integration result corresponding to each time interval, where an abscissa in the instantaneous flow rate curve may correspond to the time interval and an ordinate in the instantaneous flow rate curve may correspond to the instantaneous flow rate corresponding to each time interval.

Furthermore, the control terminal can judge whether the first mass flow meter is abnormal according to the instantaneous flow curve, and when the peak with the amplitude exceeding a preset amplitude threshold value is detected in the instantaneous flow curve, the first mass flow meter is indicated to be abnormal, and then early warning information used for representing the first mass flow meter to remind a worker to check the first mass flow meter in time can be generated.

It can be understood that, in the embodiment of the present application, integration processing may be further performed on the second feed liquid accumulation amount in combination with time intervals, and an instantaneous flow rate curve is generated by using each time interval and an integration result corresponding to each time interval, so as to determine whether the second mass flow meter is abnormal.

As a further optional option of the embodiment of the present application, after the generating the early warning information corresponding to the abnormality of the first mass flow meter when it is determined that there is a spike whose amplitude exceeds the preset amplitude threshold, the method further includes:

when the second feeding amount is detected not to be in the preset feeding amount interval, determining the flow rate of the feed liquid based on the preset feeding amount interval and the preset time interval;

After determining that the first mass flow meter is abnormal, in order to ensure normal operation of charging, the control terminal may further calculate the second charging amount within a preset time interval according to the second material liquid accumulation amount and the material accumulation amount, and the calculation method may refer to the above-mentioned embodiments, which is not described herein in detail.

Further, when the second feeding amount is detected not to be in the preset feeding amount interval, the current feeding rate is indicated to be not meeting the requirement, and then an ideal feed liquid flow can be calculated by combining the preset feeding amount interval and the material accumulation amount, wherein the ideal feed liquid flow can be calculated by multiplying the intermediate value of the preset feeding amount interval by the material accumulation amount and dividing the product by a preset time interval.

And 108, calculating an accumulated value deviation rate according to the accumulated value deviation value, the material accumulated amount and a preset charging parameter, and sending second early warning information when the accumulated value deviation rate is detected to exceed a preset deviation rate interval.

Specifically, after acquiring the accumulated amount of the material input into the feeding machine collected by the electronic belt scale, the control terminal may further, but is not limited to, substitute the accumulated amount deviation value, the accumulated amount of the material, and the preset feeding parameter into a preset accumulated value deviation ratio calculation formula to obtain the accumulated value deviation ratio of the first mass flow meter and the second mass flow meter in the same time interval, where the preset accumulated value deviation ratio calculation formula may be represented as follows:

in the above formula, the first and second carbon atoms are,

may correspond to the cumulative amount of feed liquid collected by the first mass flow meter during the ith time interval,

can correspond to the accumulation amount of the feed liquid collected by the second mass flowmeter at the ith time interval, and the accumulation amount of the feed liquid collected by the second mass flowmeter at the ith time interval>

Can be a fixed difference value corresponding to the accumulation amount of the first mass flow meter and the second mass flow meter in the charging process, and can be combined with the accumulation amount of the second mass flow meter in the charging process>

Can be correspondingly accumulated and/or picked up by the electronic belt scale at the ith time interval>

May correspond to preset charging parameters.

Further, when the fact that the accumulated value deviation rate of the first mass flowmeter and the second mass flowmeter exceeds a preset deviation rate interval in the same time interval is detected, it is indicated that the error of the current feeding process is large, operation needs to be stopped in time, and early warning information used for representing operation stop is generated so as to inform workers of closing all the devices in time and repairing all the devices.

As a further option of the embodiment of the present application, the feeding pipeline system further includes a first electromagnetic valve disposed between the gear pump and the first mass flow meter, a bypass pipeline disposed in parallel with the first mass flow meter and the first electromagnetic valve, and a second electromagnetic valve disposed on the bypass pipeline;

After the first mass flow meter is determined to be abnormal, in order to maintain normal operation of feeding, the control terminal can control the feeding pipeline where the first mass flow meter is located to be closed through the electromagnetic valve.
