Bolt screwing state judgment method, bolt screwing operation end and screwing system

The invention relates to a bolt screwing state judgment method, a bolt screwing operation end and a bolt screwing system. The bolt screwing state judgment method comprises the steps that first data and second data sent by the operation end are acquired; according to the model of the bolt screwing area, the first data and the second data, the operation end screwing point position is determined; and the screwing state of the bolt at the screwing point position is set to be a screwed state. According to the invention, the operation end can send the collected first data and second data when screwing the bolt, the computer determines the screwing point location of the operation end through the first data and the second data, and can judge the screwing state of the bolt, so that a worker can intuitively know whether the screwing missing situation occurs according to the screwing state of the bolt on the computer, and the work efficiency is improved. And screwing does not need to be carried out according to a specif
