Abstract: The present invention belongs to the field of automation equipment predictive maintenance, and relates to a method for diagnosing health of a CNC machine tool. Parameters such as vibration and temperature are detected by Zigbee nodes adopted in the present invention and uploaded to a Zigbee gateway. The detected data is transmitted by the Zigbee gateway to a cloud server for digital signal processing, data mining and analysis processing. After a training test of the above data is carried out by the cloud server, a health degree model is obtained. The health degree model is transmitted by the cloud server to the Zigbee gateway. A clock circuit can be used for synchronizing system time and recording time as data is recorded. For the on-line predictive maintenance of a CNC machine tool, the most rapid and accurate predictive maintenance information is provided.

Abstract: Methods and devices for detecting electrical arcs are provided. A first wavelet transformation with a first mother wavelet is applied to a chronological sequence of current measurements (80) of a current through a lead, to obtain first wavelet coefficients. In addition, a second wavelet transformation with a second mother wavelet different from the first mother wavelet is applied to the chronological sequence in order to obtain second wavelet coefficients. On the basis of the first wavelet coefficients and the second wavelet coefficients, it is then determined whether an arc (10; 11; 24) is present.

Abstract: Systems and methods include a computer-implemented method for generating a detailed heterogeneities map of a main reservoir. Pressure data for multiple wells of a main reservoir is received during a simultaneous field shut-in of the multiple wells. A scaled rate of change of pressure for each well is determined using the pressure data for each well. Rates of change of pressure for the multiple wells are plotted using the scaled rates of change of pressure. Clusters of wells having rates of change of pressure within a threshold difference of other wells in a given cluster are determined based on the plotting. A detailed heterogeneities map of the main reservoir is generated based the clusters of wells. The heterogeneities map defines heterogeneous regions. Each region contains a set of wells assigned to the heterogeneous region based on the wells having similar rates of change of pressure.

Abstract: The present invention discloses an isolation circuit having test mechanism. An isolation circuit component performs signal transmission when a signal that a control terminal receives has an enabling state and performs signal isolation when the signal has a disabling state. The test circuit includes a multiplexer and a control circuit. Under a shifting operation state in a test mode, the control circuit controls the multiplexer to select an operation input terminal to receive and output an isolation control signal having the enabling state to the control input terminal. Under a capturing operation state in the test mode, the control circuit controls the multiplexer to select a test input terminal to receive and output the test signal to the control input terminal. The control circuit further determines whether the isolation circuit performs signal transmission or signal isolation according to the signals at the data input terminal and the data output terminal.
