According to the communication protocol of inner system of certain aerial camera focusing system

this paper investigated the real-time display method of the aerial camera focusing system during communication. A new method of real-time display using simulation technology was presented based on computer arithmetic control and communication control circuit.The work principle of the aerial camera focusing system was described;the circuit was designed; the flow of the software was described. The camera crew under the simulation software basing on VC ++ 6.0

can also focus on the four camera system control with the features of simple operation and high reliability.
