When the monitoring unit 6 obtains the deviation mark information after comparing the target mark information with the preset mark information, the deviation mark information is compared with the preset alarm threshold. If the deviation mark information is greater than the preset alarm threshold, it can be judged that the marking operation of the marking unit 2 is abnormal, such as when the position of the marking information in the deviation mark information on the photovoltaic component is offset, if the offset is greater than the offset range set in the preset alarm threshold, the alarm unit 7 is activated and alarms; or when the deviation mark information is the percentage of the unfinished amount of the marking trajectory of the photovoltaic component, for example, the preset alarm threshold is set to 3% of the unfinished amount percentage, and the percentage of the unfinished amount in the deviation mark information is 5% greater than the preset alarm threshold of 3%, it can be judged that the marking operation is abnormal, and the alarm unit 7 alarms.
