摘要： A noise generation cause estimation device capable of easily estimating the cause of noise generation in a factory is connected for communication with a plurality of machines in the factory. The noise generation cause estimation device is provided with a noise information acquisition unit configured to acquire noise information generated in the machines, an operation information acquisition unit configured to continually acquire operation information of all the machines, and a determination unit configured to learn the relevance between the noise information and the operation information. The determination unit is provided with a state observation unit configured to observe the noise information and the operation information as state variables indicative of a current state of the environment and a learning unit configured to form a plurality of clusters including the state variables.

摘要： A noise monitoring device capable of easily estimating a noise generation source in a factory is connected for communication with a plurality of machines in the factory. The noise monitoring device is provided with a noise information acquisition unit configured to acquire noise information including the time of generation of noise if the noise is generated in the machines, an operation information acquisition unit configured to continually acquire operation information of all the machines, a determination unit configured to extract the operation information at a point in time near the noise generation time, and a display unit configured to display the noise information and the operation information of all the machines at the point in time near the noise generation time.

摘要： In a numerical control system including a numerical controller and a plurality of I/O units, a serial communication signal monitoring circuit is included inside the I/O unit to monitor a serial communication signal (data and an idle signal). When a state is detected in which a serial communication signal is high or low for a predetermined time or longer, the numerical control system acknowledges the state as disconnection of the serial communication signal, and generates a reset pulse signal to reset an internal register of the I/O unit. With this configuration, when the power supply of the numerical controller is turned off/on, it is unnecessary to turn off/on the power supply of the I/O unit.
