A user-friendly Central Control System (CCS) for the pulsed high magnetic field facility has been designed and implemented at the Wuhan National High Magnetic Field Center (WHMFC). The CCS is composed of the server, the Human Machine Interface (HMI) and the configuration tool. The controlled objects and functions of the CCS are introduced first, and then the design and implementation of key functions are given. The CCS is developed on basis of a client/server mode, so multiple users can use the system simultaneously. To achieve higher pulsed magnetic fields, a synchronous trigger sequence is used, which can trigger up to 13 power modules to be discharged into a magnet with multiple coils. Benefiting from component technology and the TCP/IP communication protocol, the CCS can monitor signals in real time and receive experimental data from recording devices running on different platforms. The test results show that the CCS meets the requirements of experiments and simplifies the control operation.
