Research And Design A System For The Scene After The Earthquake Information Collection Based On OMAP Platform

Earthquake is one of the most severe disasters. In order to minimize the casualties, property damages and social impacts caused by the earthquake, the focus should be improving the accuracy of real-time earthquake prediction and increasing the efficiency of the rescue team. Unfortunately, earthquake prediction is still in research stage. Then in the presence of earthequake, in order to reduce the disater losses, the key point is to expedite the rescue process and increase the rescue efficiency. After the earthquake, the complexity of the environment makes it mandatory to have a efficient system for information acquisition and processing, which collects informations like: damage of buildings, fire out of control, landslide, dam breach, nuclear leakage etc. This system will not only guarantee the safety of the rescue team member, but also improve the efficiency of emergency relief to reduce disaster losses and protect people's lives and propertyBased on OMAP platform, we design a system for real-time, on-site information collection. The information collected includes two aspects: First, security information of the rescue team member(heart rate, respiration, body temperature, blood pressure); the second is on-site environmental information (buildings and surface damage, fire, floods, hazardous gas leaks, landslides, landslide, debris flow, lake, etc.). According to application requirements, this system includes the following subsystems : data acquisition subsystem, the image acquisition subsystem, touch and display subsystem. Data acquisition subsystem and the image acquisition subsystem are in charge of the information collection. Touch and display subsystem facilitate the interface between the computer and human.The main processor of this system is OMAP-L138 form TI company with dual-core structure, including 375/456-MhzARM926EJ-S RISC MPU and 375/456-Mhz C6748 VLIW DSP, also, with a variety of functional external interfaces. The OMAP-L138 is a dual-core processor, which provides a powerful DSP core for image processing. ARM verification system for data storage and control functions provides developers with a high degree of flexibility so that they can add intuitive man-machine interface, touch screen or network function. This article introduces the flexibility of the embedded system useing highly transplantable Bootloader. It also discusses the operating system for embedded Linux transplantation, dual-core communication mechanisms for DSPLINK and cross-compiling and debugging in OMAP platform.The tool used for dugging is CCS (Code Composer Studio, code debugger).
