The invention relates to the technical field of production line detection, aims to solve the problem of product false rejection caused by false triggering of a detection device, and provides a false touch correction system suitable for a production line, which comprises a first photoelectric sensor, a controller, an acquisition device and the detection device. The method comprises the following steps: 1, after a to-be-detected product triggers a first photoelectric sensor, the first photoelectric sensor sends a detection signal to a controller connected with the first photoelectric sensor; 2, the controller receives the detection signal, records the detection time t0 and issues an acquisition instruction to the acquisition device; 3, the acquisition device acquires to-be-detected data of the to-be-detected product and transmits the to-be-detected data to the detection device; 4, the detection device receives the to-be-detected data and obtains the receiving time t1 of the to-be-detected data, when the time difference between t0 and t1 is smaller than a threshold value, the trigger is valid, the detection device detects the to-be-detected product according to the to-be-detected data, otherwise, the trigger is invalid, and the detection device ignores the to-be-detected data. By adopting the mode, the problem of false elimination caused by false triggering can be effectively avoided.
