摘要： A field programmable gate array (FPGA) in a machine health monitoring (MHM) module includes interface circuitry, vibration data processing circuitry, and tachometer data processing circuitry. The interface circuitry de-multiplexes a synchronous serial data stream comprising multiple multiplexed data channels, each containing machine vibration data or tachometer data, into separate input data streams. The vibration data processing circuitry comprises parallel processing channels for the separate input data streams containing vibration data, each channel including a highpass filter, two stages of integration circuits, a digital tracking bandpass filter, and multiple parallel scalar calculation channels. The tachometer data processing circuitry processes the tachometer data to generate RPM and other values. A cross-point switch in the FPGA distributes tachometer signals between MHM modules in a distributed control system, thereby allowing multiple modules to share tachometer information.

摘要： A machine having a drive that directly or indirectly excites vibrations in the machine over a frequency range when the drive is connected to the power supply. A sensor detects a time-dependent signal that is characteristic of the excited vibrations. The time-dependent signal is transmitted to a control device that analyzes the frequency of the time-dependent signal and relates the frequency analysis to the excitation that produces the excitation and uses this relationship to determine a state of at least one element of the machine. The control device outputs a message to an operator of the machine on the basis of the state that is determined. Preferably, the control device applies an interference variable that has at least one frequency inside the frequency range to the drive so as to excite vibrations. The interference variable may be a sinusoidal interference variable whose frequency passes through the frequency range, or a pseudobinary interference variable whose spectrum covers the frequency range. If the drive is an electrical three-phase drive, asymmetrical energization may be used.

A determination unit determines whether an anomaly exists before the machine tool machines the workpiece and while the machine tool is machining the workpiece, and whether there is a fault in the machine tool, based on the classification results from the first and the second neural networks, deviation history between weight coefficients of neurons in an output layer included in the first neural network and the amounts of characteristics extracted by the first characteristics extracting unit, and deviation history between weight coefficients of neurons in an output layer included in the second neural network and the amounts of characteristics extracted by the second characteristics extracting unit.

摘要： A device for estimating machining dimensions of a machine tool which employs tool members each being rotatably driven by a driving unit includes: a vibration sensor; a characteristics extracting unit for extracting amounts of characteristics from an output of the vibration sensor; a neural network for classifying the amounts of characteristics into categories; and a conversion unit. Amounts of characteristics of generated output by racing the tool member are used for training the neural network, and inputted again to the trained competitive learning neural network to excite neurons so that the relationships between Euclidean distances and machining dimensions of workpieces are registered in the conversion unit. The Euclidean distances are obtained between weight vectors of the excited neurons and respective corresponding training samples, and the machining dimensions are obtained when the workpieces are machined by the tool members at the same condition as the respective corresponding training samples are obtained.

摘要： The present invention relates to a mobile system and a moving method of the mobile system. According to the present invention, a natural period is measured from a vibration component signal generated by a force due to acceleration/deceleration of wheels, and the mobile system moves by applying an acceleration profile containing an acceleration period or a deceleration period based on the natural period. Therefore, the acceleration profile based on the natural period is applied such that vibration that is visible to a user is not generated during acceleration and deceleration of the mobile system. As a result, quality of the mobile system is improved.
