【Abstract】 The system of measurement and control to the granary and situation of grains is controlled by a two-level computer, and it has the structure of a topology with a concentration line network. It takes IPC-610P pentium as the main computer and intel MCS-96 chip calculator as the subordinate frame. It uses RS-485 concentration line to fulfil the semi-duplex communication between the monitoring points and the subordinate computer. It uses the design of software program so as to realize the structurization of the program and the modularity of the functions.更多还原
