A glass magnesium board curing maintenance system comprises a channel, the two ends of the channel are directly communicated, the channel can allow maintenance vehicles to go through, and a rail allowing the maintenance vehicles to run is arranged at the bottom of the channel. A plurality of exhaust fans are evenly distributed at the top of the channel along the axis, and at least one cold and hot air pipe is arranged at the bottom of the channel. A plurality of temperature and humidity sensors are evenly distributed in the channel along the axis, and rolling gates are arranged at the two ends of the channel. According to the glass magnesium board curing maintenance system, the channel structure is adopted, constant temperature and humidity control of curing temperature of 20-30 DEG C and humidity of 65-75% can be conveniently achieved through the cooperation of the exhaust fans, the cold and hot air pipes and the rolling gates. An arranged control device and the arranged electric rolling gates can achieve automatic constant temperature and humidity control, and therefore the labor intensity of workers is reduced. An arranged arc top and an arranged water collecting tank can collect condensation water, therefore, the condensation water is prevented from dripping on a half-finished glass magnesium board, and quality is further guaranteed.
