The invention relates to a engineering machinery equipment data remote monitoring system, which comprises a data intranet structure used for acquiring data of a working process of the whole system, asystem extranet structure used for transmitting the data acquired by means of the data intranet structure, and a processing structure used for processing and displaying the data, wherein the data intranet structure comprises a plurality of tension data intelligent processing instruments. The engineering machinery equipment data remote monitoring system has the advantage that owners, supervisors, construction units and detection units are unified on the same Internet platform, the data is exchanged in real time, the geographical restrictions are broken through, the precast beam yards and bridgeprestressed tension construction quality situations are grasped timely, and the management and control purposes of ''real-time tracking, intelligent control, and timely error correction'' are achieved.
