Abnormality Detection System, Molding Machine System, Abnormality Detection Apparatus, Abnormality Detection Method and Non-Transitory Computer Readable Recording Medium

An abnormality detection apparatus detecting an abnormality of a production device, comprising:

• a communication unit that receives operating data that is transmitted from a control device performing operation control of the production device, the operating data the operation control;
• an acquisition unit that acquires time-series sensor value data output from a sensor detecting a physical quantity related to operation of the production device or a product manufactured by the production device;
• and
• a processing unit that calculates statistics of the sensor value data acquired by the acquisition unit and determines a presence or an absence of an abnormality of the manufacturing device based on the statistics calculated and a threshold depending on the operating data acquired,
• wherein the communication unit transmits the operating data and the sensor value data to an external diagnostic apparatus that diagnoses a condition of the production device, receives a diagnostic result transmitted from the diagnostic apparatus and transmits a determination result from the processing unit, the statistics and the diagnostic result received to the control device.

An abnormality detection method causing a computer to execute processing of detecting an abnormality of a production device, wherein the computer executes the processing of:

• receiving operating data that is transmitted from a control device performing operation control of the production device, the operating data of the operation control;
• acquiring time-series sensor value data output from a sensor that detects a physical quantity related to operation of the production device or a product manufactured by the production device;
• calculating statistics of the sensor value data acquired;
• determining a presence or an absence of an abnormality of the manufacturing device based on the statistics calculated and a threshold depending on the operating data acquired;
• transmitting the operating data and the sensor value data to an external diagnostic apparatus that diagnoses a condition of the production device;
• and
• receiving a diagnostic result transmitted from the diagnostic apparatus and transmitting a determination result indicating a presence or an absence of an abnormality, the statistics and the diagnostic result received to the control device.

A non-transitory computer readable recording medium storing a computer program causing a computer to execute processing of detecting an abnormality of a production device, wherein the computer executes the processing of:

• acquiring time-series sensor value data output from a sensor that detects a physical quantity related to operation of the production device or a product manufactured by the production device;
• calculating statistics of the sensor value data acquired;
• determining a presence or an absence of an abnormality of the manufacturing device based on the statistics calculated and a threshold depending on the operating data acquired;
• transmitting the operating data and the sensor value data to an external diagnostic apparatus that diagnoses a condition of the production device;
• and
• receiving a diagnostic result transmitted from the diagnostic apparatus and transmitting a determination result indicating a presence or an absence of an abnormality, the statistics and the diagnostic result received to the control device.
