The invention relates to the technical field of concrete prefabricated slab production and provides a
control system and method for a fixed mold table intelligent maintenance unit. The control systemcomprises a maintenance unit, a PLC, a human-computer
interaction interface and
signal acquisition equipment. The maintenance unit comprises
softened water equipment, an electromagnetic boiler, a circulating water pump, a heating
pipe, a steam generator and an exhaust hose. According to the
control system, heating and humidification are controlled in a separated manner, and the temperature,
humidity and temperature rise and fall rates are precisely controlled; the time is strictly controlled, the phenomenon that the surface has cracks due to severe temperature change can be prevented, and theproduct quality is guaranteed;
electric equipment is adopted, no harmful gas such as
nitrogen gas and
oxide gas is generated in the process, and quite high
environmental protection performance is achieved; an almost closed heating
pipe system is adopted,
water consumption caused by heating is little, and only a certain amount of water is consumed in the product humidifying process; and the final condensate water is collected and can be utilized cyclically, and
water resources can be effectively saved.
