Hot working multi-process data feedback method based on industrial internet of things

A hot working multi-process data feedback method based on an industrial internet of things specifically comprises the steps of setting a network distribution vector for a traditional node by using a modified CTS-to-sef frame to enable the traditional node to enter a sleep or dome state so as to be compatible with traditional equipment, sending hot working multi-process request data transmission to an AP/access point by using a modified RTS frame, dividing into two time slots, and sending the hot working multi-process request data transmission to the AP/access point; the first time slot sensing equipment feeds back and transmits data to the relay node; the second time slot sensing device directly feeds back data to the source end, the access point AP feeds back and transmits the data to the source end in an orthogonal frequency mode, and finally the source end carries out maximum-ratio merging on the received data to obtain more accurate data, so that the problem of efficient data transmission of multiple proc
