Embodiment approach

[0036]If the actual pressure data of the pipe network is less than the lower pressure limit, it means that the pressure of the pipe network is too low, and it is necessary to increase the pressure of the pipe network to make it within the normal value range. Since the number of air compressors is closely related to the pressure of the pipe network, the more air compressors are used, the more compressed air is injected into the pipe network, and the pressure of the pipe network will be greater. Therefore, if the actual pressure data of the pipe network is less than the lower pressure limit, the start-up logic sequence is used to control the opening of the air compressors, that is, to increase the number of air compressors, and to control the input of a part of the air compressors from the stopped air compressors. (Installing the air compressor is to start the air compressor), the number of input air compressors increases, and the pressure of the pipe network will increase. A sp...

Abstract

The invention belongs to the technical field of air compressor control and provides an automatic control method and an automatic control device for an air compressor, an air compressor system and a computer readable medium. The automatic control method for the air compressor comprises the following steps: acquiring the actual pressure data of a pipe network and comparing the actual pressure data with an upper limit value and a lower limit value of a pressure; if the actual pressure data is smaller than the lower limit value of the pressure, controlling starting of the air compressor accordingto a starting logic sequence till the actual pressure data is greater than or equal to the lower limit value of the pressure; and if the actual pressure data is greater than the upper limit value of the pressure, controlling halting of the air compressor according to a halting logic sequence till the actual pressure data is smaller than or equal to the upper limit value of the pressure. The automatic control method for the air compressor is applied to producing colored energy-saving glass. Compared with a manual adjusting mode, the stability of a gas source of a production line can be improved, so that the quality of the glass is improved favorably.

Description

technical field [0001] The present application belongs to the technical field of air compressor control, and in particular relates to an air compressor automatic control method, device, system and computer readable medium. Background technique [0002] At present, in the float glass production process, a certain pressure of compressed air is required for product cooling, fuel combustion, environmental protection injection, instrument and valve assist, etc. Usually, an air compressor station is set up and compressed by a screw air compressor. Air supply, therefore, the reliable operation of the air compressor is very important. The pressure of the pipe network connected to the compressed gas output end of the air compressor determines the required compressed air, and then determines the normal production. Then, it is necessary to ensure that the pressure of the pipe network is within a normal data range. However, the current control methods of air compressors are all manual ...
