The invention discloses a method for detecting printing machines. The method includes acquiring corresponding relations between input line marks in the printing machines and working state information of the printing machines according to signal change conditions of signal transmission lines when the printing machines work normally; enabling the printing machines to carry out test operation under the control and acquiring corresponding relations among the input line marks in the printing machines, output line marks and the working state information of the printing machines according to the corresponding relations between the input line marks in the printing machines and the working state information of the printing machines and corresponding relations between the input line marks in the printing machines and the output line marks; processing transmission signals of each output line mark corresponding to a piece of working state information according to the corresponding relations among the input line marks, the output line marks and the working state information, and computing and outputting transmission time intervals between signals of the input line marks and the signals of the corresponding output line marks. The method has the advantages that reference bases can be provided for evaluation schemes for the stability and the reliability of electric control levels by the aid of the method, and effects of assisting in detecting electric control systems of the printing machines can be realized.
Description
technical field [0001] The invention relates to electrical control, in particular to a detection method for a printing machine. Background technique [0002] The stability and reliability of the printing press, including the stability and reliability of the mechanical mechanism and electrical control system. In the prior art, the detection of printing machines is mostly to detect the stability and reliability of the mechanical mechanism level, but there are few detection schemes for the stability and reliability of the electrical control level. If the electrical control system of the printing machine fails, it will also cause the printing machine to not work normally. [0003] There is currently no effective solution to the problem of lack of detection and evaluation schemes for the stability and reliability of the printing machine at the electrical control level, which makes it difficult to ensure the normal operation of the printing machine.
