The following describes in detail a control method of an air compressor according to an embodiment of the present application with reference to the accompanying drawings.

The control method of the air compressor provided by the embodiment of the application comprises the following steps: the control device trains a process of obtaining a model (referred to as a model training process for short) according to the operation data, preset data and a preset algorithm of the air compressor and a process of controlling the air compressor according to a target value determined by the model (referred to as a control process for short) by the control device.

The "model training procedure" is described first below.

As shown in fig. 4, the "model training process" includes: S501-S503.

S501, the control device obtains first data and target data of the air compressor.

Wherein the first data comprises power, efficiency and gas production of the air compressor in a first time period. The target data comprises a preset power range, a preset efficiency range and a preset gas production range of the air compressor.

Specifically, the control device may use the first data of the air compressor as a variable, use the target data of the air compressor as a target function, and establish a model through a preset algorithm to obtain the optimal power, the optimal efficiency, and the optimal gas production rate of the air compressor.

Illustratively, the maximum power of the air compressor is 15 kilowatts, the maximum efficiency is 98%, and the maximum gas production is 8 kilograms. However, the optimum power, optimum efficiency and optimum gas production of the air compressor are not necessarily the maximum values. Therefore, the control device obtains the preset power range of the air compressor between 10 kilowatts and 15 kilowatts, the preset efficiency range between 85% and 98% and the preset gas production range between 5 kilograms and 8 kilograms.

S502, the control device determines the flow matching degree of the air compressor and the air storage tank.

The flow matching degree is the matching degree between the gas production rate of the air compressor in the first time period and the gas storage rate of the gas storage tank in the first time period.

Optionally, when determining the flow matching degree of the air compressor and the air storage tank, the control device first obtains the pressure and the volume of the air at the outlet of the air storage tank in the first time period, and then determines the flow matching degree of the air compressor and the air storage tank according to the pressure and the volume of the air at the outlet of the air storage tank in the first time period and the air yield of the air compressor in the first time period.

Illustratively, the pressure P of the air at the outlet of the air reservoir during the first time period is preset, and the volume V of the air at the outlet of the air reservoir during the first time period is preset. According to the ideal gas state equation, the following steps are obtained:

PV=nRT

where n is the amount of substance, R is a first constant, and T is the absolute temperature.

And carrying out time differentiation on the ideal gas state equation, and determining the flow matching degree of the air compressor and the air storage tank according to a time differentiation formula. The flow matching degree of the air compressor and the air storage tank meets the following formula:

where t is a unit time and a is a second constant.

And S503, training by the control device according to the first data, the target data, the flow matching degree of the air compressor and the air storage tank and a preset algorithm to obtain a model.

After the first data and the target data are obtained and the flow matching degree of the air compressor and the air storage tank is determined, the control device takes the first data of the air compressor and the flow matching degree of the air compressor and the air storage tank as variables, takes the target data of the air compressor as a target function, and obtains a model through training of a preset algorithm.

Optionally, the preset algorithm may be a multi-objective optimization continuous domain ant colony algorithm, or may be other preset algorithms, which is not limited in this embodiment of the present application. When the control device obtains the model according to the training of the multi-objective optimized continuous domain ant colony algorithm, the specific implementation steps of the multi-objective optimized continuous domain ant colony algorithm can refer to the description of the multi-objective optimized continuous domain ant colony algorithm in the prior art, and the embodiment of the application is not repeated herein.

Optionally, when the control device uses the first data of the air compressor as a variable and uses the target data of the air compressor as a target function and obtains the model through the training of the preset algorithm, in order to improve the accuracy of the model, other target functions may be added, for example: the pipe wall thickness, the pipeline diameter, the pipeline gas transmission pressure, the pipeline strength, the pressure of an air inlet and an air outlet of an air compressor and the like of the industrial system.

Optionally, when the control device uses the first data of the air compressor and the flow matching degree of the air compressor and the air storage tank as variables, the control device can also process the power, efficiency and air yield of the air compressor in the first time period. Illustratively, an empirical mode decomposition algorithm is adopted to decompose the pressure of air at the outlet of the air storage tank in a first time period into inherent mode functions with different frequencies and temperatures, denoising and dimensionality reduction are carried out based on a principal component analysis method, original random vectors related to components are converted into new unrelated random vectors by means of orthogonal transformation, reduced data after dimensionality reduction are sent into a support vector machine to be trained, the functional relation between the pressure of the air at the outlet of the air storage tank and the air yield of the air compressor in the first time period is obtained, and the functional relation between the pressure of the air at the outlet of the air storage tank and the air yield of the air compressor in the first time period is used as a variable, so that the output result of a model obtained through training is more accurate.

Optionally, when the control device uses the target data of the air compressor as the target function, the control device may further obtain the loss power of the air compressor, and adjust the target function in combination with the preset power range of the air compressor, so that the output result of the model obtained by training is more accurate.

The "control flow" is described next.

After the model is trained by adopting the method, the control device of the air compressor can control the air compressor according to the target numerical value output by the model. In the "control flow", the model obtained by the above process is a pre-trained model. As shown in fig. 5, includes: S601-S603.

S601, the control device obtains the pressure, the volume and the temperature of air at the outlet of the air storage tank at the first moment.

Wherein the first time is after the first time period.

Optionally, a pressure gauge, a flow meter, a temperature gauge and the like may be installed at the outlet of the air storage tank, so that the control device obtains the pressure of the air at the outlet of the air storage tank at the first time according to the pressure gauge. Correspondingly, the control device obtains the volume of air at the outlet of the air storage tank at the first moment according to the flow meter. Correspondingly, the control device obtains the temperature of the air at the outlet of the air storage tank at the first moment according to the thermometer.

Optionally, after the pressure gauge detects the pressure of air at the outlet of the air tank at the first time, the flow meter detects the volume of air at the outlet of the air tank at the first time, and the temperature gauge detects the temperature of air at the outlet of the air tank at the first time, the pressure gauge, the flow meter, and the temperature gauge may send the pressure, the volume, and the temperature of air at the outlet of the air tank at the first time to the control device through a fifth generation mobile communication technology (5th generation mobile networks, 5G) gateway. Compared with the existing common gateway, the 5G gateway has the characteristics of large connection, high bandwidth and low time delay. The control device obtains the pressure, the volume and the temperature of the air at the outlet of the air storage tank at the first moment through the 5G gateway, so that the time delay can be reduced, and the efficiency is improved.

S602, the control device inputs the pressure, the volume and the temperature of the air at the outlet of the air storage tank at the first moment into a pre-trained model to determine a target value.

The target value is used for determining the running state of the air compressor.

And S603, controlling the air compressor by the control device according to the target numerical value.

After the control device determines the target value, the air compressor can be controlled according to the target value. Specifically, if the target numerical value meets a first preset condition, the air compressor is controlled to be closed to operate. And if the target value meets a second preset condition, controlling the air compressor to start to operate for a target preset time period at the target power.

For example, the control device sets in advance a control strategy corresponding to the value of the model output as follows: when the output target value is 0, controlling the air compressor to be closed to operate; when the output target value is 1, controlling the air compressor to start and operate for 1 hour at 80% of power; and when the output target value is 2, controlling the air compressor to start and operate for 2 hours at the maximum power.

The embodiment of the application provides a control method of an air compressor, which is applied to an industrial system comprising an air storage tank and the air compressor and comprises the following steps: the control device obtains the pressure, the volume and the temperature of air at the outlet of the air storage tank at the first moment, inputs the pressure, the volume and the temperature of the air at the outlet of the air storage tank at the first moment into a pre-trained model to determine a target numerical value for determining the running state of the air compressor, and then controls the air compressor according to the target numerical value.

It can be seen that the control device of the air compressor processes the pressure, the volume and the temperature of the air at the outlet of the air storage tank at the first moment through a pre-trained model to determine a target value for determining the operation state of the air compressor, and then controls the air compressor according to the target value. Compared with the prior art, the method and the device for controlling the air compressors can quickly and accurately determine the target numerical value for determining the running state of the air compressors, control the air compressors according to the target numerical value, do not need workers to manually set the target numerical value of each air compressor (such as running time, running power and the like of the air compressors), and improve the efficiency of controlling the air compressors in the industrial system.
