PROBLEM TO BE SOLVED: To provide a system that can be more simply utilized at a low cost in a driving device using compressed air.SOLUTION: A control system for pneumatic equipment comprises: a compressor for compressing air; a piping for feeding compressed air generated by the compressor; a driving device driven by the compressed air supplied through the piping; and a switching unit switching turning-on and turning-off of the driving device. The switching unit is provided with power generation means for generating power using compressed air, and the power generation means is interposed more on upstream-side piping from the driving device. There are also provided a control part for generating control signal; an oscillator for outputting a control signal generated at the control part into the piping as a sound wave signal; and a detection unit for detecting the sound wave signal in the piping. The driving device is drive-controlled by operating the switching unit on the basis of a signal output from the detection unit.SELECTED DRAWING: Figure 1 |
