1. A state monitoring system for stirring-degassing processing that is performed while revolving and rotating a container containing a processing target material in a stirring-degassing apparatus, the state monitoring system comprising:
a sensor unit comprising a temperature sensor configured to determine a temperature of the processing target material, and a first transmitter-receiver configured to transmit output values of the temperature sensor to a computer; and
the computer comprising a second transmitter-receiver, an information recorder, and a processor, wherein the second transmitter-receiver is configured to receive the output values of the temperature sensor transmitted by the first transmitter-receiver;
wherein the processor of the computer is configured to:
record, before the processor causes the container to revolve and rotate, a first temporal change in the information recorder, the first temporal change being based on at least one selected from the group consisting of: a rate of increase of the output values; a rate of reduction of the output values; a change in the rate of increase of the output values; and a change in the rate of reduction of the output values;
start the stirring-degassing processing, wherein, when starting the stirring-degassing processing, the processor is configured to cause the container to revolve and rotate;
compare, during the stirring-degassing processing, the first temporal change to a second temporal change, the second temporal change being based on at least one selected from the group consisting of: the rate of increase of the output values while the container is revolving and rotating; the rate of reduction of the output values while the container is revolving and rotating; the change in the rate of increase of the output values while the container is revolving and rotating; and the change in the rate of reduction of the output values while the container is revolving and rotating; and
performing, based on the comparison of the first temporal change to the second temporal change, a post-comparison action, which is (i) outputting an alarm, (ii) stopping the stirring-degassing processing, (iii) outputting an operation instruction for the stirring-degassing apparatus, (iv) determining a state or a state transition of the processing target material according to the second temporal change that appeared in the output values of the temperature sensor during the stirring-degassing processing, (v) recording that the stirring-degassing processing has been normally executed, (vi) recording that the stirring-degassing processing has not been normally executed, or (vii) recording that the second temporal change could not be detected in the output values of the temperature sensor obtained during the stirring-degassing processing.
