  The setting unit 23 may be configured to transmit setting information including a sampling number corresponding to the predetermined number to the acceleration sensor 151 in addition to the sampling frequency (step S2). In this case, the setting unit 23 does not need to repeat the transmission of the setting information after the setting information is transmitted until the sampling number measurement information arrives from the acceleration sensor 151.

  The predetermined number may be 1.

  FIG. 9 is a flowchart defining an operation procedure when the information processing apparatus according to the embodiment of the present invention processes a frame.

  With reference to FIG. 9, first, the receiving unit 31 receives a frame transmitted from the measurement information transmitting apparatus 101 via the measurement information relay apparatus 111 and the internal network 401 (step S11).

  Next, as described above, the processing unit 32 calculates the amplitude and effective value of the vibration to be managed from the measurement result included in the frame received by the receiving unit 31 (step S12).

  Next, using the calculation result, the processing unit 32 performs processing such as display of contents as shown in FIG. 6 and determination of abnormality due to change in effective value over time (step S13).

  FIG. 10 is a flowchart defining another example of an operation procedure when the information processing apparatus according to the embodiment of the present invention processes a frame.

  Referring to FIG. 10, first, the receiving unit 31 receives a frame transmitted from the measurement information transmitting apparatus 101 via the measurement information relay apparatus 111 and the internal network 401 (step S21).

  Next, as described above, the processing unit 32 uses the sampling frequency included in the frame received by the receiving unit 31 to perform an FFT operation on a plurality of measurement results indicated by the measurement information included in the frame. (Step S22).

  By the way, in the management system, it is conceivable to monitor the vibration of a rotating device such as a motor and a pump using an acceleration sensor. However, the vibration mode of the rotating device varies depending on the type of the rotating device, the load status, aging degradation, temperature, and the like, and it is not easy to establish an optimal monitoring method.

  Specifically, for example, it is necessary to initialize the determination condition for the measurement result of the acceleration sensor according to the equipment such as a rotating device, and it is necessary to set a correct value depending on the model number such as a load and a bearing. When a large number of acceleration sensors are arranged, the operation is difficult.
