The invention discloses a manufacturing production line based on the internet of things. The manufacturing production line comprises a casting process, an extrusion process and a coloring process. Thecasting process, the extrusion process and the coloring process are correspondingly provided with real-time monitoring devices. A wireless transmission module is arranged in each real-time monitoringdevice. In the casting process, a dosing device, a charging device, an aluminum alloy smelting device, a first slagging-off device, a standing device, a second slagging-off device, an ash frying device, an aluminum alloy refining device, alloying equipment, a casting device and a first saw-cutting device are included and connected through a production line connecting device. The ash frying deviceis located between the first slagging-off device and the alloying equipment and between the second slagging-off device and the aluminum alloy refining device in a fixedly connected manner. Accordingto the manufacturing production line based on the internet of things, the whole manufacturing production line can be monitored in real time through the additionally-arranged real-time monitoring devices, transmission is achieved through the wireless transmission module so that management of working staff can be facilitated, the production efficiency is improved, and the safety of the production line is improved.
