Step D1: and recording the time of the storage information received by the window of the storage medium.
Wherein the printed electronic edition manuscript is divided into a plurality of storage information to be transmitted to the storage medium, and the time of the storage information is respectively set as
Wherein the time record is updated in real-time. Preferably, the storage information received by the storage medium is numbered, wherein the time of arrival of the storage information corresponds to the number of several storage information, e.g. the first storage information is in
Time of arrival, second storage information at

After that
The moment is reached, and so on, the nth stored information is
Interval time interval
After that
The moment is reached.
Preferably, the storage information can be divided and transmitted in a frame dividing manner in the prior art, so that the storage medium can receive the storage information uninterruptedly and number the storage information conveniently.

Step P2: the printed score was used as the output layer.
Wherein the printing score is a composite score for the printing process based on the printing data and the result of the printing error check within the designated time, and the printing score is used as a neuron of the output layer.
Preferably, a rating standard may be preset, for example, the number of the printing data is in a specified proportion to the final printing error result, and the rating standard is modified and set by a worker, and the setting in other ways is not limited herein.
Step P3: the design of the neural network implicit neurons is performed.
The neural network prediction model has hidden neuron number, and excessive hidden neuron number can increase network calculation amount and easily generate overfitting problem; if the number of the neurons is too small, the network performance is affected and the expected effect cannot be achieved.
Specifically, the determination of the number of implicit neurons may be performed according to the following formula:
Wherein
Represents the number of neurons of the input layer,
represents the number of neurons of the output layer,
is [1,10 ]]The constant between the two can be selected according to actual needs.
Step P4: and training the network neural model.
Specifically, the neural network model is constructed through the determination of the input layer, the output layer and the hidden layer. The training of the network can be performed through a neural network toolbox in MATLAB, and the specific training process is not repeated herein, which refers to the prior art.
Step P5: and checking whether the simulated printing has errors or not through the output printing score.
Specifically, if the print score is higher than the predetermined threshold, the print score in the entire print data is acquired. Preferably, the plurality of scores are summed and averaged, and if the average printing score is still higher than the designated threshold, it indicates that there is a low possibility that an error occurs after the entire print data is formally printed, and then there is no error, and step S150 is performed. Otherwise, the flow exits.
Step S150: the printing process is executed based on the print data in the analog printing.
Specifically, since the formal printing is predicted according to the simulated printing data, the formal printing can be directly printed according to the printing data in the simulated printing without acquiring the printing data again, and the printing accuracy is ensured.
