摘要
目前,在向钢筋数控加工设备录入钢筋尺寸时,仍然依赖于钢筋加工工人手工录入信息,这种方式既容易造成信息录入错误,也严重降低了钢筋加工效率。本文提出了一种从IFC文件提取钢筋加工数据,并将其以数字化方式传递给钢筋数控加工设备的方法。该方法从IFC文件中解析并提取钢筋实体信息,将其按BVBS格式进行编码后,再将编码转换为PDF417条码格式提交给钢筋加工工人;在钢筋加工厂,钢筋加工工人采用扫描二维码的方式将钢筋加工信息输入到MEP钢筋数控加工设备。该方法已在德州至上饶国家高速公路合肥至枞阳段项目得到成功应用。应用实践表明,该技术可将IFC格式的钢筋模型转换为数控加工文件,减少了工人读图、录入等中间环节,可以提高钢筋的加工效率和精度。
The rebar size is manually input into the numerical control processing equipment of the rebar by steel bar processing workers,which might lead to the error information input and seriously lowered processing efficiency of rebar.In response to it,a method of extracting steel processing data from the IFC file and digitally transmitting it to CNC rebar machining equipment was proposed in this paper,through which,rebar entity formation is parsed and extracted from the IFC file and then encoded in BVBS format.On this basis,the coded data converted into PDF417 barcode format is submitted to rebar processing workers.Rebar processing workers in the processing factory input rebar processing information into MEP rebar CNC machining equipment via scanning QR codes.This proposed method has been applied in the Hefei-Zongyang Section of the Dezhou-Shangrao National Expressway.The technology in the paper is proven to be effective in cutting the intermediate links such as workers’diagram reading and input and improving the processing efficiency and accuracy of rebar through converting the steel bar model in IFC format into CNC machining files.
