The present application relates to the technical field of conveying counting, in particular to a counting
system and method based on
welding parts, the
system comprising a
welding part shielding event identification module, a shielding event trajectory identification module, a
welding part passing section identification module, a repeated shielding identification module and a welding part counting output module.In the present application, the sequence of actions before and after is determined by identifying the instantaneous start and end time of the welding part
cutting into and
cutting off the
light beam, the continuous motion trajectory is screened and the physical passing section is divided by comparing the time interval of adjacent actions, the repeated shielding is checked by introducing the time interval and dynamic change direction triggered by double-beam light, the counting trigger node is determined and the register is driven to increase one by one, the
dynamic mapping of the motion process to
digital recording is realized, the
signal jitter and nonlinear movement interference are eliminated, the unique corresponding relationship of the statistical value in the flow state is locked, the production data is recorded on the bottom logic, the error counting conflict under dynamic working conditions is resolved, and the counting value is restored to the real passing part state of the
production line.
