Abstract

The application relates to the field of glass carbon preparation, in particular to an automatic monitoring system and method applied to glass carbon preparation. The system comprises: an impurity monitoring module which is used for monitoring a first type of concentration index of a first type of impurity generated in a heating stage, the impurity including carbon monoxide, carbon dioxide, nitric oxide, nitrogen dioxide or nitrogen; a signal adjusting module which is used for automatically adjusting a centralized heat preservation method according to the concentration index and the current state of the centralized heat preservation method; the signal adjusting module comprises a first adjusting unit which is used for controlling a gradient control module to reduce a pyrolysis heat preservation time length when the centralized heat preservation method enters a preset pyrolysis carbonization temperature and reaches a first set time and the pyrolysis heat preservation time length is not reached, and the first concentration index belongs to a first concentration threshold range. The automatic monitoring system in the application can realize centralized monitoring for the pyrolysis treatment stage, and then dynamically adjust the pyrolysis treatment condition.
