The invention belongs to the technical field of big data, and discloses a big data based intelligent factory manufacturing management system. The big data based intelligent factory manufacturing management system comprises an integrated control system, a material transmission system, a data acquisition analysis and monitoring system, a communication system, a workshop central management and control system. According to the system, the relevant conditions can be conveniently acquired by workers, timely feeding back and processing can be carried out, the management quality of a production and manufacturing enterprise can be effectively improved, the production cost is reduced, and the serial processes among the operation processes of original equipment are changed into parallel processes among the operation processes, the full-process management of numerical control machining is realized, the efficiency and the rhythm of each preparation link are determined before the numerical control equipment is used for machining parts as well, and the abnormality and the delay situation of execution of a program in the production preparation process can be quickly positioned; and when a system judges that the machining plan condition is met, the machining program, a process document, the tool list information can be automatically sent to a station, the on-time production is realized, and theproduction efficiency of the machinery manufacturing enterprise is obviously improved.
