摘　　要：Ion cyclotron wave resonance heating system(ICRH)which is one of the most important auxiliary system in EAST provides conditions for heating the plasma.In order to make the whole transmission network of ICRH form the required state,the coaxial switching system was developed,which mainly consists of 11 same coaxial switches.Each coaxial switch has a controller with an RS485 communication interface and is able to switch between two states.All controllers are integrated to an RS485 hub which connects to the computer.A master computer software is developed to control the coaxial switching system so as to achieve the state needs of ICRH.Moreover,several rounds of experiments show that the coaxial switching system operates reliably.The coaxial switching system has already been applied to normal use currently.
