| Abstract: |
| The thesis introduces the principle of the MWS and the designing methods of hardware circuits and control programs.According to the principle of the electric resistance method to test the water,a series of the microcomputer CHMOS-51 are adopted to control in the equipment.Using the semi-conductor temperature transducer,it realized the functions of semi-automatic test,auto-temperature compensation,liquid crystal display and speech hint.It has typical features,such as rapid test,steady data with high accuracy and easy to use etc. |
| Key words: microcomputer control cotton moisture content moisture measuring atparatus auto-temperature compensation |
