PROBLEM TO BE SOLVED: To provide a compressor number control system enabling highly reliable communication with less wiring work load.SOLUTION: A compressor number control system includes a plurality of compressors 2 and a compressor number controller 5 for controlling the compressors 2, and uses radio communication for communication between the compressors 2 and the compressor number controller 5 with a compressed air pipeline 6 as a transmission path. With the compressed air pipeline 5 as a radio transmission path, new wiring work is not required. Also, since the compressed air pipeline 6 is a transmission path shielded from the outside, stable communication is enabled without receiving interference from other radio equipment and without affecting the outside. |
