The unique spatial data handling capability and non - replaceable of gis , made it become an important technology and solution that has spatial data characteristic and gis has become one of the most important information system . academy and engineering circles have paid more attention on the development of gis Gis所具有的独特的空间数据处理能力和不可替代性，使其成为具有空间数据特性的事务处理中的一个重要技术手段和解决方案，成为最重要的信息处理系统之一，学术界与工程界都越来越关注地理信息系统的发展。
There are two innovations in the hardware system in currency sorter field . one of the innovations is that the powerful chip lpc2210 of arm series is applied on the test instrument for liquid crystal display module . and expand external memory ensure the large data volume because the ratio of small size tft - lcd and the quantity of test picture are increasing . because the powerful capabilities of processing datum of lpc2210 , the test instrument is much faster and higher performance / price ratio than traditional test instrument and portable . the other one is the test instrument combine the 本系统在该领域的创新点有两点,一是将高性能arm核心芯片lpc2210应用到液晶显示模块测试系统中,并通过外部扩充存储器,满足了小尺寸tft面板在分辨率不断提高,测试画面增加的情况下对测试系统大数据容量的需求。且由于arm系列芯片强大的数据处理能力,使得该测试系统相对传统的测试机速度更快,性价比更高,且更加轻巧。
