1. A method of monitoring a rotating equipment with a condition monitoring device, wherein the condition monitoring device comprises a plurality of sensors for monitoring one or more parameters associated with the rotating equipment, the method comprising:
performing in every predetermined time period, after every predetermined time interval:
a. detecting presence of vibration in the rotating equipment based on a signal associated with vibration in the rotating equipment, wherein the signal is measured with one or more sensors of the plurality of sensors and corresponds to a measurement location of the one or more sensors based on a placement of the condition monitoring device relative to the rotating equipment;
b. acquiring upon detecting the presence of vibration in the rotating equipment, a predefined number of samples associated with the vibration at a first frequency, wherein the predetermined number of samples are acquired using the one or more sensors;
c. calculating a Root Mean Square (RMS) value of vibration using the predefined number of samples;
d. comparing the calculated RMS value of vibration with a reference value, for detecting an operating status of the rotating equipment, wherein the reference value is calculated from data measured with the plurality of sensors at a beginning of every predetermined time period and is based on vibration data measured at the beginning of every predetermined time period;
e. storing the operating status of the rotating equipment for a plurality of predetermined time interval based on the comparison; and
f. processing information stored for the plurality of predetermined time intervals in the predetermined time period, to assess a condition of the rotating equipment.
