Exception handling method during coaxial cable communication in spraying room

The invention discloses an exception handling method during coaxial cable communication in a spraying room, which comprises the following steps: detecting whether an abnormal phenomenon exists in a coaxial cable communication network or not; and if so, switching a device control disc to be at a single action operation mode, and if not, keeping the device control disc at a continuous action operation mode. The exception handling method has the advantages of shielding coaxial cable communication exception, keeping the continuous operation of a device, eliminating impacts on production caused by the coaxial cable communication exception of a spray room system, and ensuring product quality.
