RFID technology is an untouched automatic identification technology, which can identify object automatically and acquire the relative data. It has the advantages of needing no manly intervention and being able to work in severe environment. Thus RFID technology has been used in many fields such as mechanics, material flow, electric power system etc. Although in-situ structure health monitoring has been researched almost forty years, many important problems have not been resolved, such as position identification of damage occurring in large scale structure, pre-evaluation of civil structure usage lifespan, etc. And also there are quantities of structure parameters which can not be acquired through in-situ health monitoring technology. Especially for the long span urban evaluated bridges and tunnels, the advantage of in-situ health monitoring is less obviously. In some means, manly structure inspection is the sufficiently supplement to in-situ health monitoring technology. Therefore, in this paper, a new urban railway structure inspection system is developed by adopting RFID system and personal digital assistant.
