Problems solved by technology

[0009] To sum up, the existing networked control system of air compressors is affected by many technical and conditional factors, which increases the complexity of the software and hardware structure of the control system, especially it is difficult to solve the "massive" data in the networked control system of air compressors. The instability of communication transmission makes the equipment of the air compressor networked control system expensive and lacks security and stability

A power source supplies power to the PLC control module, the air compressor unit, the freezing dryer unit, the suction dryer unit, the pressure sensor unit and the touch screen respectively. According to the air compressor unit networking control system of the PROFIBUS bussing technique, a PROFIBUS on-site bussing technique is used, complete software and hardware support is provided for PLC control, the stability and the reliability of the system are enhanced, and safe and reliable operation of the system is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of industrial bus of an air compressor unit networking control system, and in particular relates to an air compressor unit networking control system based on PROFIBUS bus technology. Background technique [0002] In large-scale production, multiple air compressors need to be operated in tandem. In the prior art, there are three main networking control technologies for air compressors: [0003] The first way is manual operation, which is mainly judged by workers' subjective experience, and the instrument is operated to realize the control function. It often depends on the proficiency control of the operator, and has extremely high requirements on the quality of the operator. [0004] The second way is automatic control, which mainly replaces manual operation by computer control to realize simple automatic control. [0005] The third way is network control, which can meet the requirements of remote data ...
