Multichannel High Voltage Power Supply Controls Solution Using Compact Distributed Ethernet Based Boards and Qt Based GUI

Compact low cost Ethernet based remote controller boards have been developed and tested for distributed control of many DC-DC high voltage power supplies(0-2000V) to be used in large Neutron detector array at IUAC. The boards can be distributed over LAN using network switches for interconnect. Each board has its own unique MAC and IP address for independent read write operations. A 24 channel power supply system, each channel having a compact two layer board with the DC-DC HV converter, mounted on top layer, has been built and tested successfully to power detectors. A user friendly GUI has been developed using Qt as the preferred language which is compatible to both Linux and Windows. The advantage of such a system is that, it is easily expandable to a large number of power supplies, low cost, globally accessible, multiple users in a network can set or read any power supply value through a software control panel developed either as a simple browser based HTTP client or versatile HLL interface using LabVIEW, C++ etc. and OS independent.

The Cryogenic Data Acquisition and Control system (CRYO-DACS) at IUAC was commissioned successfully in the year 2002 and has been continuously in operation since then with uptime better than 95%. The aim of CRYO-DACS is to control and acquire many analog and digital cryogenic parameters of super conducting LINAC and related equipments like beam-line cryostats, helium compressors, cryogenic distribution etc. The complete system is implemented using two VME crates, housing I/O modules, placed far apart and interconnected using Ethernet. The software implementation and maintenance have also been trouble-free which used IOWORKS as the development tool for embedded CPUs running VxWORKS. The OPC Client was developed using VB6 & MSACCESS RDBMS for data logging, viewing and trending under Windows 2000 stable server. In summary, this paper will elaborate the implementation, use and related failures faced for last 10 years and the subsequent corrective actions taken to keep the system running for such a long time round the clock along with some future plans.
