It should be noted that fig. 1 is only an example of an embodiment of the present invention, and the present invention is not limited thereto.
Based on the control system of the micro metering system, fig. 2 illustrates a flow of a control method of the micro metering system according to an embodiment of the present invention. The process may be performed by the control system of the micro-metering system described above.
As shown in fig. 2, the process specifically includes:
The state information of the micro-weighing hopper may include at least one of an in-hopper weight, a hopper weighing weight, an upper weight limit of the micro-weighing hopper, and a lower weight limit of the micro-weighing hopper, which is not particularly limited in the embodiment of the present invention.

By the scheme, the signal interaction between the micro-metering hopper and the upper computer is perfected through the collection of the classified information.
Specifically, the upper mechanism theory calculates whether the weight in the micro-metering hopper can meet the requirement of multiple times of production before production.
And 203, if the feeding device does not meet the requirement, controlling the feeding device to feed the micro-metering hopper.
In one possible embodiment, if the weight in the hopper does not meet the production goal, the feeding device is controlled to feed the micro-metering hopper until the weight in the hopper reaches the upper weight limit of the micro-metering hopper.

In the embodiment of the invention, the variable speed weight threshold value of the feeding motor comprises a large input value of a frequency converter of the feeding motor, a medium input value of the frequency converter and a small input value of the frequency converter.
The large value of the frequency converter, the medium value of the frequency converter and the small value of the frequency converter correspond to different feeding speeds of the feeding motor.
For example, the large input value of the frequency converter is 0.3kg, the medium input value of the frequency converter is 0.2kg, and the small input value of the frequency converter is 0.1kg. When the residual feeding of the feeding motor is not more than 0.3kg, the feeding speed of the feeding motor is a first speed, when the residual feeding of the feeding motor is not more than 0.2kg, the feeding speed of the feeding motor is a second speed, and when the residual feeding of the feeding motor is not more than 0.1kg, the feeding speed of the feeding motor is a third speed.
According to the scheme, the micro metering system can timely adjust metering deviation through setting or modifying the variable speed weight threshold value of the feeding motor.
Further, fig. 4 schematically illustrates a flow of a micro-metering system control method according to an embodiment of the present invention. The process may be performed by the control system of the micro-metering system described above.

And 405, the upper computer reads the state of the micro-metering system in real time, and if the micro-metering system fails or the metering deviation of the system is overlarge, the alarm prompt and the production suspension are carried out.
According to the scheme, the control instruction of the micro metering system is remotely modified through the upper computer, so that the metering deviation is quickly adjusted, the operation is simple and convenient, faults are timely processed, the micro metering system is controlled to start and stop, and the waste rate is reduced.
Further, fig. 5 schematically illustrates a flow of a micro-metering system control method according to an embodiment of the present invention.
