Design And Implementation Of The Monitoring System Of Electric Information Center Based On OPAM 3530

Electric power information center room is the hub of power enterprise information systems.It is responsible for collecting all of the power information and monitoring the condition of the power equipment. It must report the troubleshooting rapidly if it detects the failed state.Electricity information room monitoring system is to monitor the environment of the computer room.It is the key point to ensure the stable operation of the computer room. The main work of monitoring system is to monitor the power equipment, environmental conditions, security equipment and the operating parameters of those IT equipments. The proposal of the Smart grid has put forward higher requirements for the renewal and development of electric power information center room equipment.It introduced the realization of this monitoring host system, which takes TI’s OMAP3530 processor as the controller.This new monitoring host has higher performance, faster speed, and also added more features than the traditional monitor host which based on ARM9 processors.The system hardware design include the monitoring circuit design and the PCB design. The master module circuits take the Cortex-A8 controller OMAP3530 as the host controller.The maximum operating frequency of the OMAP3530 reaches up to 1GHz. And it also designed the DDR,FLASH, power management circuit, LCD touch screen,buffer circuit, voice alarm module and GPRS module. The communication module circuits include JTAG, RS-232,RS-485, USB, Ethernet and SD card.DDR and FLASH circuits achieved by one chip HYH0SQJ0MF3P-5L60E-C.It reduces the PCB area. Interface circuit designs the direction isolated circuits.It can reduce the interference.Discus the PCB design and the signal integrity analysis.Describe the layer stack of the PCB, the overall layout and the route of the DDR section.The chapter of this software design described the build of embedded software system based on the OMAP3530 controller.It compares and analyses the choice of the Linux operation system at first.And then describes the set up of software compiling and debugging environment.It gives detailed analysis of the U-boot startup process. Besides, it detailed analyses the transplant and cutting method of the Linux 2.6.22 kernel which this system uses, and root file system make methods.The debugging part of the monitoring system introduces the hardware and software system debugging methods and steps.Introduces the welding and inspection work of the PCB, the power supply module debugging, the core circuit debugging,the interface and GPRS circuit debugging, secondly, it introduces the debugging of software system, introduces the application of Linux system debugging method and Ethernet data services debugging work-And finally it introduces the debugging work of the hole system.The hardware of the system meet the requirements, the functional interface works well,the circuit works stability.The software needs to be further improved.
