Abstract: A low power vibration sensor and wireless transmitter system has one or more sensors that sense parameters of a machine including vibration and produces dynamic signals representing the sensed parameters. The system converts the signals to a digital format, digitally filters the signals, and processes the signals. A processor determines a plurality of levels, which represent the characteristics of the signal such as the peak value of a predetermined set of data points of the digital signal. Together, the levels comprise a PeakVue waveform. The processor determines the peak level value for the PeakVue waveform. Also, a true root-mean-square is calculated as the signal is received at the processor. The peak level and the RMS value are communicated wirelessly by a communication module to a control protocol network such as a daisy chain HART or Fieldbus protocol network. The system power supply and the communication module power supply are separate and allow for low power operation.

Abstract: In a method for transmitting data in an HVDCT system to a control system for HVDCT systems, measured values are transmitted from measuring units of the HVDCT system to preprocessing units connected to one another in series. The preprocessing units use the received measured values to generate measured value data. The measured value data are transmitted as part of a data record composed of data words, and the data words are subdivided, during transmission, into a temporal sequence of individual bit groups. A first bit group contains identification data for the preprocessing unit and information on the number of further bit groups that are to be transmitted by the preprocessing unit. A downstream preprocessing unit uses the information on the number of bit groups to be transmitted by a preprocessing unit connected upstream of it to determine a time for transmitting the data word of the downstream preprocessing unit.
