Design of the Master Control System of the Array Antenna Based on the VxWorks

This paper aimed at the features of the array antenna that with large number units, short work cycle, complex electromagnetic environment and high stability requirement, designed the master control system which based on the VxWorks real-time operating system. The master control system as a whole array antenna control center needed to connect multiple subsystems. After a full investigation, the paper proposed the following scheme: used the Ethernet port for the remote control and received status information feedback, RS485 serial port to receive external data, set up the CAN network to connect the slave machines, to achieve the control of the array antenna.
