The invention discloses a machine learning-based early warning method and device for a chemical industry park. By acquiring the historical sensor data of the target location, the historical sensor data is classified according to the early warning status, and finally the classified data are respectively input into the pre-established Mathematical models are trained to obtain predictive models. Since each historical sensor data is real and has a corresponding warning state, in addition, the model does not train a single data, so it can better reflect the correlation between the historical sensor data, Make the early warning model more accurate. After the prediction model is obtained, if the real-time data is input into the prediction model, the accuracy of the prediction result obtained will be higher. In addition, the calculation process of this method is relatively simple, and no manual calculation is required, which saves labor costs.

The present invention discloses a configuration method of a network chip calendar in a mixed rate mode, which includes setting an interval counter and a list of effective flag bits for each queue in the scheduler, and traversing all the queues when each round of convergence starts to calculate, if all If the interval counter value corresponding to the queue index is greater than the index itself, then select the queue whose effective flag bit is 1 and has the smallest interval counter and remove it from the effective flag bit list; otherwise, select the queue with the smallest interval counter from the effective flag bit list queue, and remove it from the list of valid flags; after that, all interval counters are decremented by 1, and the selected queue resets the interval counter. The invention can automatically produce calendar configuration without manual calculation, especially when multi-rate mixing and the total bandwidth of all members in the scheduler are close to the physical limit of the scheduler, it can greatly reduce the complexity of system configuration and improve the efficiency of system development.
