| Abstract: | A food drying equipment QTM with the function of air conditioning is introduced and a serial intelligent system of measurement and control based on superordinate computer and subordinate computer is studied.The 89C51 is adopted to realize the detection and intelligent control of multi-channel ambient parameters including temperature,humidity,air composition and the material weight;a PC is adopted to realize visual display and proeessing on line parameters and establishment of expert knowledge base.Moreover,the limited number of I/O port inside single chip microcontroller is relieved by serial communication;and the effective control of complicated ambient temperature,humidity and air composition is realized by fuzzy control in combination with fuzzy self adaptive PID control,in which the temperature has the adjustable function of cooling or heating. |
