PROBLEM TO BE SOLVED: To minimize an impact of control board failure, given to entire pump device control.SOLUTION: A plurality of radio communication boards 200, to which pressure sensors 50, inverter 60a to 60n, and control boards 110a to 110n are connected, having independent power supply circuits 30, are provided. The radio communication boards 200 includes radio communication circuits 240 for inputting/outputting a signal among other radio communication boards 200, the pressure sensors 50, the inverters 60a to 60n, signal input/output ports 250a to 250k for inputting/outputting signals among the control boards 110a to 110n, control parts 220 for controlling the pressure sensors 50, the inverters 60a to 60n and the control boards 110a to 110n through the radio communication circuits 240 and the signal input/output ports 250a to 250k, and storage parts 221 for storing programs for controlling the pressure sensors 50, inverters, and the control boards 110 to 110n by the control parts 220. |
