The finite element analysis (FEA) result is compared with the result form computation using mathematical equation and an experimental result which cited from Fongsamootr T. and Chartpuk P. [2006]. It is found that the FEA result has deviation about 1% and 8% respectively. Traffic sign post structure is exerted by three forces in the same time; body force, Vehicle-Induced Gusts and wind load. The higher stiffener plate leads to decrease of maximum stress at the column base. Height extension of stiffener plate from 250 to 350 mm with fixed thickness and base width leads to increase in the safety factor of column and stiffener plate. Rectangular stiffener plate with cut off a corner (type C) is the best type for supporting the base of traffic sign post column. Cutting of a corner of rectangular stiffener plate results increase of stress in itself but less than maximum stress in traffic sign post column.","PeriodicalId":319762,"journal":{"name":"2012 7th International Forum on Strategic Technology (IFOST)","volume":"463 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121168675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To guarantee the safety of miners' life and the positioning of a miner's location exactly on real time are important tasks. ZigBee technique, for its low power consumption, low cost and convenience, is proper to be used in the positioning system for underground coal mine [1]. In this paper, a new positioning algorithm for coal mine underground based on ZigBee technology is proposed, in which NNSS (Nearest Neighboring signal strength) is adopted for preliminary location, and then DTM (dynamic triangular measurement) locating method is employed for precise ranging and position. The system with the algorithm for coal mine enterprises provides personnel tracking, monitoring and other functions [2]. When an accident happens, the system can determine positions of miners and numbers of miners in time, to ensure emergent rescues and guarantee the life safety with high efficiency.","PeriodicalId":319762,"journal":{"name":"2012 7th International Forum on Strategic Technology (IFOST)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115254813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
