And the calculating unit is used for calculating the pollution coefficient of the paper report, and stopping the printer when the pollution coefficient is greater than a preset fourth threshold value.
Preferably, the paper report pollution coefficient is calculated based on the formula four:
Wherein G is the pollution coefficient of paper report, Z is the total number of judging areas, For the maximum gray value difference in the kth judgment region,/> For the total number of the sampled judgment points in the kth judgment region,/> For the gray value of the d first judgment point in the k judgment area,/> is the gray value of the d second judgment point in the k judgment area,/> Is the x-direction coordinate of the d first judgment point in the k judgment area,/> Is the x-direction coordinate of the d second judgment point in the k judgment area,/> Is the y-direction coordinate of the d first judgment point in the k judgment area,/> The y-direction coordinate of the d second judgment point in the k judgment area; e is a natural constant and takes a value of 2.72.
In this embodiment 3, the printing is performed once at intervals, so as to evaluate the status of the current printing device, and the printing is performed only after the status is normal;
the beneficial effects of the technical scheme are as follows:
When the nozzle breaks down, ink blocking or ink leakage can occur, the ink blocking can cause blank to be generated in the area of the printing content of the paper report image, the ink leakage can cause the pollution to the area which is originally blank in the paper report image by leaked ink, no matter the ink blocking or ink leakage can cause abnormal gray value difference to be generated in the relative ratio of partial areas in the paper report image to the same area in the preview image, the area which generates the abnormal gray value difference is regarded as the gray value difference abnormal area, and the gray value difference of a plurality of corresponding first judging points and second judging points in each judging area is calculated to obtain the proportion that the gray value difference abnormal area occupies the whole judging area in each judging area, so that the influence degree of pollution to the paper report caused by the nozzle break is obtained.
And generating coordinates based on a second rectangular coordinate system for the first judgment point and the second judgment point by establishing the second rectangular coordinate system, avoiding the influence caused by the integral deviation of the printing content when calculating the pollution coefficient, improving the analysis accuracy, and judging the influence degree of the dislocation of the printing content caused by the paper deviation in the printing process on the pollution of the paper report by respectively comparing the coordinates of each first judgment point and each second judgment point.
The pollution coefficient of the whole paper report is obtained by comprehensively considering the pollution degree of the paper report caused by the fault of the spray head and the pollution degree of the paper report caused by the dislocation of the printing content in the printing process, when the pollution of the paper report exceeds a preset threshold value, the pollution degree of the printed report reaches the reading influence degree, the printing work of the printing device is required to be stopped, and the printing device can be put into operation again after overhauling. By setting the fourth threshold value for the pollution coefficient of the paper report, the printing operation can be performed after the report printed by the printing device is prompted in the printing process under the condition that the reading is not influenced, a large number of devices are simultaneously failed to cause untimely maintenance, so that a large number of devices cannot work, a large number of printers are queued in front of a small number of devices which work normally to influence the report acquisition efficiency, meanwhile, the buffer area is set to effectively reduce the working pressure of the maintainer, and simultaneously, the maintenance order can be guided by the maintainer, the maintenance order is ensured to be determined according to the damage condition of the printing device, the printing device with more serious failure condition can be temporarily repaired, the equipment which still can work continuously can be temporarily maintained after the equipment with more serious failure condition is repaired, more printing devices are provided for providing printing service for the printers, the queuing time of the printers is shortened, and the acquisition efficiency of the diagnosis report is improved.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
