  • Patent number: 10656637
    Abstract: A monitoring system applied to a shaping machine having a high speed electricity meter. The monitoring system includes a current obtaining device and an analyzing device. The current obtaining device is coupled to the high speed electricity meter to obtain a plurality of current signals from the operated shaping machine and in respond to the shaping machine executes a machining program, the current obtaining device extracts current variation data from the current signals. The machining program corresponds to a piece of the current variation data. The piece of the current variation datum comprises a maximum current and an occurring time that the maximum current being recorded. The analyzing device is configured to calculate a gap, based on the maximum currents and the occurring times corresponding to at least two successive machining programs. In respond to the gap time exceeding a predetermined threshold, the analyzing device generates a warning signal.

  • Publication number: 20190158602
    Abstract: A data collecting system includes a management server, a number of data collecting chains. Each data collecting chain includes a computer connected to the management server, at least one sensor and a data acquisition (DAQ), coupled to the sensor(s) and connected to the computer through RS485, configured to acquire sensing data from the sensor(s) and transmit the sensing data to the computer. The DAQs are connected to the computers through a wireless backup transmission interface. The management server sends a first confirmation signal to the computers. When at least one of the computers does not respond to the first confirmation signal, the management server indicates the computers which have responded to the first confirmation signal to receive the sensing data from the DAQ(s) corresponding to the computer(s) which doesn't respond to the first confirmation signal through the wireless backup transmission interface.

  • Publication number: 20190155246
    Abstract: An evaluation system applied on shaping machine, in which the shaping machine has a controller and an electricity meter. The evaluation system includes a parameter obtaining device and an evaluation device. The parameter obtaining device communicatively coupled to the controller and the electricity meter. The parameter obtaining device is configured to obtain a plurality of parameter data regarding a machining program from the controller and the electricity meter. The evaluation device is electrically coupled to the parameter obtaining device, the evaluation device configured to transform the parameter data into numerical parameters to extract a bolster plate position value and a motor current value, multiply the bolster plate position value and the motor current value with weights and sum up the weighted bolster plate position value and the weighted motor current value as an evaluation score.
