A typical feature of AdvancedTCA is high reliability, which qualifies ATCA a new generation bus. The Intelligent Platform Management system guarantees the reliability of ATCA based system. The High Performance Compute Node (HPCN) designed for the PANDA Data Acquisition and Trigger system conforms to the AdvancedTCA specifications. Also, it will be used for the upgrade of the BESIII Trigger system. The IPMC designed by us provides abundant functions for board level management, such as Hot Swap, negotiation for power supply, status monitoring of devices on board, communication with Shelf MC. In the first part, application of IPMI in new generation bus is introduced; in the second part, management needed for the HPCN board is analyzed; Design of IPMC module for HPCN is presented at last part.

It designed a remote monitoring system of BESIII experiment based on web. The software of the system is mainly based on module programming. The Ajax technology and the MVC pattern is used in system framework construction. The function of selecting multiple tables is realized by structural checkbox tree using jstree library. Data chart is plotted by HighCharts library. The updating of data curve is realized by the method of calculating the time span between the real data record to measure the http request. The schema and the tecgbikigy of the system design can be used by detector monitoring system like BESIII. Source

It is devoted to the study and implementation on image processing of BESIII DAQ database infomation. The generated graph which is filled with the data from database search pages with JpGraph library is sent to the browser. It is convenient to be inquired online by members. JpGraph library is completely written in PHP. Source

The software and hardware design of a 16 channel online dose rate monitoring system is presented. After being amplified and A/D converted, the output signal of the sensors was sent to a microprocessor through an FPGA, where the low-frequency filter, calculation, temperature compensation and pedestal deduction were accomplished. Such steps corrected the variation of dark current dependent on temperature fluctuations in a effective way, and finally the instantaneous dose rate results with enough precise were obtained. Source
