In the processing process of the workpiece, the production line operation data comprises workpiece type data, workpiece yield data, machine operation state data, dangerous working condition data and the like, all types of subdata are stored through leaf nodes, and the child nodes are used for storing parent-level labels.
The data generated by processing need to pass through a signal port and be stored in a storage module in the acquisition and storage processes, and because the data represent different meanings, a special channel is needed for the signal to pass through, and the type and the quantity of the data are increased by geometric multiples in the face of the requirements of faster and more accurate production lines.

Therefore, when a flexible production line is faced, a lot of time is consumed for debugging, and when some sudden conditions are met, for example, a lot of workpieces have some defects, different types of signal transmission speeds are inconsistent, and due to the barrel effect, the transmission of other signals is also suspended, so that the data transmission speed has a bottleneck.

the working process of the time delay module is started after the temporary data channel is formed, and the formed temporary data channel is kept for a specified time
And after the time is over, the temporary data channel is de-electrified and decomposed to form independent signal ports again, and when the temporary data channel is prolonged, the delay module is used for timing again.
7. The production line operational data collection and storage system based on the directory hash tree as claimed in claim 6, wherein: the formed temporary data channel of the delay module is kept for a set time
The determination method comprises the following steps:
wherein
For a specified extended time for the temporary data channel,
for the time taken for this type of signal transmission,
the time taken for the temporary data channel tag module activation process,
to trigger the time for the temporary data channel to form,
the time of the interval between two passes of the same type of signal.
8. The production line operational data collection and storage system based on the directory hash tree as claimed in claim 7, wherein: the operation data detection module comprises an infrared sensor, a camera, an audio receiver, a vibration sensor, a temperature sensor and a current sensor;
the data processing module comprises a workpiece defect detection module, an audio analysis module, a vibration analysis module and an analog-to-digital converter, wherein the workpiece defect detection module is electrically connected with the infrared sensor and the camera, the audio analysis module is electrically connected with the audio receiver, and the vibration analysis module is electrically connected with the vibration sensor.
