In this paper, the key technologies of Lanzhou Heavy Ion Accelerator digitalpower control system have been researched and experimented, and a digital powermonitoring system which is based on ARM has also been designed.Recording and preservation of the real-time operating data of the Power isextremely important for the accelerator’s operation and magnet power’s failurehandling. However, due to the limited of the hardware and software resources on thepower supply, the power supply cannot directly use some large-scale databasemanagement systems which can easily realise the data storage, query and otherfunctions.So the embedded database MySQL with the character of small, fast andsupporting multiple users simultaneous access integrated with the ARM embeddedsystem as the front of the entire power supply monitoring system is able to realize thereal-time data recording and accumulation of each power supply. By analysing thehistorical data, one can understand the power supply’s performance at any time, andthen improve the performance of the powers.ARM-based digital power monitoring system research and design are the mainwork of this paper. In the accelerator field at home and abroad, the research on digitalpower monitoring system based on combining multiple processors is an importantissue, because of not only the prominent role of such power monitoring system butalso the difficulty of the design of power monitoring system. This paper takes thedesign based on ARM and FPGA to implement the digital power monitoring. Compared with the domestic and foreign similar single embedded processor power,this frame is easier to expand, changing the traditional single embedded processormode, so that a large number of power running record store as possible. |
