<p>PROBLEM TO BE SOLVED: To provide a vibration signal acquisition device and a vibration monitoring system which do not require remodeling of equipment like a plant and are capable of considerably reducing the labor for monitoring a state of an inspection object device for a long period of time.SOLUTION: A vibration signal acquisition device 10 includes: a body unit 11 including a sensor part 111 which detects vibration generated by an inspection object device to generate an analog vibration signal, an A/D converter 112 for converting the analog vibration signal to a digital vibration signal, and a wireless transmitter 113 which wirelessly transmits the converted digital vibration signal; and a power generation unit 12 which converts natural energy to power to generate power. The body unit 11 and the power generation unit 12 are arranged in positions close to the inspection object device, and power to be consumed in the body unit 11 is supplied by power generation of the power generation unit 12.</p> |
