4. The system of claim 1, wherein said determining whether an anomaly has occurred in said manufacturing process based on said manufacturing data or said first image data comprises:
the data management background acquires prestored reference manufacturing data, judges whether the production manufacturing data are within a range specified by the reference manufacturing data, if so, judges that the production process is normal, otherwise, judges that the production manufacturing process is abnormal;
or,
and the data management background judges whether equipment which stops running exists in the production equipment in the production process according to the first image data, if so, the production process is judged to be abnormal, and if not, the production process is judged to be normal.
5. The system of claim 4, further comprising a second securing device for securing the first monitoring device;
the second fixing device is arranged on production equipment of the production line, and the relative position of the first monitoring equipment and the production equipment is adjusted through the second fixing device, so that whether the production equipment is in a running state or not is monitored by the first monitoring equipment.
6. The system of claim 4, wherein if the data management backend determines that the manufacturing process is abnormal, sending a prompt message to the alarm device, and after the alarm device receives the prompt message and sends an alarm message corresponding to the prompt message, the method further comprises:
if the production and manufacturing process is judged to be abnormal through the production and manufacturing data, after a first instruction for checking the reason of the abnormality of the production and manufacturing process is received after the data management, displaying the abnormal production and manufacturing data and the identification information of the production equipment corresponding to the abnormal production and manufacturing data;
and if the first image data is used for judging that the production and manufacturing process is abnormal, after receiving a second instruction for checking the reason of the abnormality in the production and manufacturing process after the data management, displaying the identification information corresponding to the production equipment which stops running and the production equipment which stops running.
7. The system of claim 3, wherein if the data management background determines that the manufacturing process is abnormal, sending a prompt message to the alarm device, and after the alarm device receives the prompt message and sends an alarm message corresponding to the prompt message, the method further comprises:
and if the second image data is used for judging that the production and manufacturing process is abnormal, after receiving a third instruction for checking the reason of the abnormality of the production and manufacturing process after the data management, displaying the second image data and the reference image data.
8. The system of claim 1, further comprising:
after receiving a third instruction for controlling the preset production line to start production, the data management background sends the third instruction to production equipment on the preset production line;
and after the production equipment on the preset production line receives the third instruction, starting the production process.
