The invention relates to the application of a computer multi-point continuous monitoring wireless control system during curing flue-cured tobacco, which belongs to the technical field of flue-cured tobacco modulating equipment. In the invention, based on the existing computer monitoring and controlling technology and by combining the specific parameters of tobacco flue-curing, a wireless network card is installed on a curing barn controller to receive and send the relevant curing information parameter; a user observation, analysis and commanding system is set up to send out 'processing reference' and 'regulation and control command'. The number of users and a monitoring point are set up randomly as required to automatically convert relative humidity level. In the invention, the computer system combines continuous monitoring and wireless regulation and control to directly measure dry-bulb temperature, relative humidity level and curing time, and completely observe humiture change curve and prior-period conditions of tobacco flue-curing, thus having the advantages that observation range is wide, investment cost is low, operation is easy, labor and time are saved, and the tobacco flue-curing technique is put into practice exactly. The application of the invention is suitable for the model of scale production of modern tobacco agriculture and intensified curing.
