Control method of long nozzle mounting equipment

The invention provides long nozzle mounting equipment which comprises a front-end module, a rear-end module, an image acquisition module, a control module, a mechanical arm and a connecting module, and a control method comprises the steps that the control module controls the mechanical arm to be connected with the rear-end module through the connecting module when receiving a long nozzle mounting signal; the mechanical arm drives the rear-end module to partially translate, so that the rear-end module is connected with the front-end module; the image acquisition module obtains the position of a collector nozzle of the current steel ladle mechanism and sends the position information to the control module; the control module controls the mechanical arm to drive the front-end module to move horizontally according to the position information of the lower nozzle until the long nozzle on the front-end module is located under the lower nozzle; the rear end module controls the front end module to rotate so that the lo
