Further, when the current of the motor is less than the current threshold of the motor and/or the current voltage of the motor is less than the voltage threshold of the motor, it is determined that the motor is a motor doing useless work, for example, the current threshold of the motor 1 is 26A, the current of the motor is 25A, and then the current of the motor is less than the current threshold of the motor, it is determined that the motor 1 is a motor doing useless work, and the current and the current voltage of the motor are both less than the current threshold and the voltage threshold of the motor, respectively; for another example, the motor 2 determines that the motor is a motor that does not work, and in the embodiment of the present application, in order to save the storage space of data, the motor that does not work on each production line is determined based on the current power consumption data and the corresponding power consumption data threshold.

Further, the current electricity consumption data may further include: the current revolution; in step S3, based on the current power consumption data and the relationship, the motor to be reduced in number of revolutions and the corresponding number of revolutions that needs to be reduced are determined from the motors that do idle work on each production line, and the method specifically may include: step S301 (not shown in the figure), step S302 (not shown in the figure), and step S303 (not shown in the figure), wherein,

and S301, determining the relation between the motor doing useless work and the motor doing useful work on each production line based on the motor doing useless work on each production line and the relation.

With the embodiment of the present application, the number of revolutions of each motor on each production line is correlated, and when the number of revolutions of one motor is reduced by the correlation, the operating efficiency of the motor related to the motor becomes slow, so after determining the motor which does not work for each production line, it is necessary to determine the relationship between the motor which does not work and the motor which does work usefully in each production line. For example, a production line includes: the motor 1 does useful work, and the motor 2 and the motor 3 do useless work, so that the relation between the motor 1 and the

motors

2 and 3 needs to be determined.

Step S302, determining the motor with the rotation number to be reduced from the motors which do idle work on each production line based on the current rotation number of each motor on each production line and the relation between the motors which do idle work and the motors which do useful work on each production line.

For the embodiment of the application, in order not to influence the working efficiency of the motors for doing useful work on the same production line, not all the motors for doing useless work need to reduce the number of revolutions, that is, the number of the motors with the number of revolutions to be reduced on each production line can be smaller than that of the motors for doing useless work on the production line; certainly, the working efficiency of the motors for doing useful work on the same production line is not influenced, and the number of the motors with the number of revolutions to be reduced on each production line can also be the number of the motors for doing the useful work on the production line.

For the embodiment of the application, in order to prevent the idle work motor from reducing the number of revolutions so as to influence the working efficiency of the idle work motor on the same production line, the motor with the number of revolutions to be reduced is determined from the idle work motors on each production line through the relation between the idle work motor and the idle work motor on each production line, the accuracy of determining the motor with the number of revolutions to be reduced is improved, and the condition that the efficiency of the production line is influenced by reducing the number of revolutions of the idle work motor is also avoided.

Step S303, determining that the motor to reduce the number of revolutions corresponds to the number of revolutions to be reduced, based on the motor to reduce the number of revolutions and the relationship between the motor to do useless work and the motor to do useful work on each production line.

For this application embodiment, after confirming to wait to reduce the revolution motor, according to waiting to reduce the relation of revolution motor and the motor of doing useful work on same production line, wait to reduce the degree of influence of revolution motor to the motor of doing useful work on same production line promptly, confirm that the motor of waiting to reduce the revolution corresponds the revolution that needs to reduce, because the degree of influence is different, the motor of waiting to reduce the revolution corresponds the revolution that needs to reduce also different. In the embodiment of the application, in order to further ensure the working efficiency of the motor for doing useful work, the determined motor for reducing the number of revolutions is more accurate to correspond to the number of revolutions to be reduced through the relation between the motor for reducing the number of revolutions and the motor for doing useful work, and the working efficiency of the motor is ensured while the motor is energy-saving.

Specifically, under the condition that the energy saving degree of the motor is maximum, the motor to be subjected to rotation number reduction on one production line is a motor which is used for performing useless work on the production line, and for the motor which is used for performing useless work, the corresponding current rotation number of the motor which is used for performing useless work is reduced, namely the rotation of the motor which is used for performing useless work on the production line is stopped, so that the electric energy is saved to the maximum degree.

Another possible implementation manner of the embodiment of the present application, if there is a motor doing useful work in any production line, determining, based on a relationship between the motor to reduce the number of revolutions and the motor doing useless work and the motor doing useful work in any production line, a number of revolutions that needs to be reduced corresponding to the motor to reduce the number of revolutions may specifically include: step Sa (not shown in the figure) and step Sb (not shown in the figure), wherein,

and step Sa, determining the degree of association between the motor with the number of revolutions to be reduced and the motor with useful work on the basis of the motor with the number of revolutions to be reduced and the relationship between the motor with useless work and the motor with useful work on any production line.

With the embodiment of the present application, the greater the degree of association between the motor to reduce the number of revolutions and the motor to do useful work, the greater the influence on the motor to do useful work, and the degree of association between the motor to reduce the number of revolutions and the motor to do useful work needs to be determined before determining that the motor to reduce the number of revolutions corresponds to the number of revolutions that needs to be reduced.

And step Sb, determining that the motor for reducing the number of revolutions corresponds to the number of revolutions to be reduced based on the motor for reducing the number of revolutions and the degree of association between the motor for reducing the number of revolutions and the motor for doing useful work.

The degree of association between the motor to reduce the number of revolutions and the motor doing useful work is inversely proportional to the number of revolutions to be reduced for the motor to reduce the number of revolutions, i.e., the greater the degree of association between the motor to reduce the number of revolutions and the motor doing useful work, the smaller the number of revolutions to be reduced for the motor to reduce the number of revolutions.

When the motor with the number of revolutions to be reduced is in minimum relation with the motor which does useful work on the same production line, namely the number of revolutions of the motor with the number of revolutions to be reduced does not influence the motor which does useful work on the same production line, the motor is directly reduced by the corresponding current number of revolutions, namely the number of revolutions of the motor with the number of revolutions to be reduced is reduced to 0.

After determining the motor of waiting to reduce the revolution and the corresponding revolution that needs to reduce through above-mentioned embodiment, the motor of waiting to reduce the revolution is adjusted according to the revolution that needs reduce, specifically can include: the varistor resistance of the motor whose number of revolutions is to be reduced is adjusted on the basis of the motor whose number of revolutions is to be reduced and the corresponding number of revolutions to be reduced.

For the embodiment of the present application, the number of revolutions of the motor to be reduced can be reduced by increasing the resistance of the frequency converter of the motor, and in the embodiment of the present application, smooth speed regulation can be obtained by changing the resistance.

In another possible implementation manner, the current electricity utilization data may further include: the current revolution; if the motors which do idle work in any production line comprise all the motors in any production line, determining the motor to be reduced in revolution and the corresponding revolution needing to be reduced from the motors which do idle work in any production line based on the current electricity utilization data and the relation, and specifically comprising the following steps of: and determining the motors of which the number of revolutions is to be reduced as all the motors on any production line and determining the number of revolutions which need to be reduced as the current number of revolutions corresponding to each motor.

With the embodiment of the application, when the motors to be reduced in the number of revolutions are all motors on any production line, because the motors do not do useful work, when the number of revolutions of the motors to be reduced in the number of revolutions is reduced, the corresponding number of revolutions is directly reduced to 0, so that the motors are more energy-saving.

Further, if all the motors on any production line need to be reduced to 0, the method for adjusting the number of revolutions of the motor to be reduced on any production line according to the number of revolutions to be reduced may specifically include: the motor to be reduced in the rotation number on any production line is adjusted to stop running by controlling the stop running of any production line.

For the embodiment of the application, when the number of revolutions of all the motors on any production line is determined to be reduced to 0, all the motors on the production line are stopped, all the motors on the production line do not need to be stopped one by one, the production line is directly controlled to stop running, and the energy-saving efficiency of the motors is improved.

Further, a possible implementation manner of the embodiment of the present application is introduced through a specific scenario, that is, for a certain production line, data acquisition is performed through a motor data acquisition device: the method comprises the steps that current power utilization data corresponding to each motor are collected, the obtained current power utilization data are uploaded to cloud equipment to be stored, further, a specific management system can also obtain the current power utilization data corresponding to each motor in a production line, the specific management system analyzes whether each motor does not work, if the motor doing not work exists in a certain production line, all the motors in the production line can be turned on and off through one key in order to save electric quantity, and in order to guarantee the working efficiency of the production line, when the motor doing not work exists in the production line, the motors with the number of revolutions to be reduced and the number of revolutions required to be reduced of each motor with the number of revolutions to be reduced in the production line can be determined; of course, if the power consumption data does not exist, the power consumption data is still collected in real time in the embodiment, and the power consumption data is stored and analyzed, which is specifically shown in fig. 2.
