s200, the vertical warehouse scheduling system writes the vehicle bodies with the smallest planned sequence numbers and the vehicle bodies with the same colors in the pre-paint marshalling vertical warehouse into the warehouse-out queue, and sequentially ex-warehouse according to the warehouse-out queue;
s300, after the execution of each ex-warehouse task is completed, the vertical warehouse scheduling system judges the production urgency of the vehicle bodies in the pre-paint marshalling stereo warehouse according to the inventory information of the post-paint storage stereo warehouse, the information of the vehicle bodies in the pre-paint marshalling stereo warehouse and the quantity information of the vehicle bodies between the pre-paint marshalling stereo warehouse and the pre-paint marshalling stereo warehouse;
s400, vehicle bodies meeting production urgency judgment standards are delivered out of the warehouse preferentially, other vehicle bodies are grouped according to spraying colors, delivery queues are generated, and delivery is carried out sequentially according to the delivery queues;
s500, according to a final assembly production demand plan, the vehicle bodies in the post-painting storage three-dimensional warehouse are sent out one by one.
7. The method for sequentially scheduling production of vehicle bodies according to claim 6, wherein the number of vehicle bodies which have been brought out of the pre-paint marshalling stereo library and have not been brought into the post-paint storage stereo library is a, the number of vehicle bodies which are delayed in repair is B, the number of vehicle bodies which have continuous ex-warehouse conditions in the post-paint storage stereo library is C, an ex-warehouse queue buffer break threshold is D, the planned sequence number of vehicle bodies which are currently brought out of the post-paint storage stereo library is E, and the planned sequence number of vehicle bodies to be scheduled in the pre-paint marshalling stereo library is F;
f of all the car bodies in the pre-paint marshalling three-dimensional warehouse are judged one by one, and whether F of a certain car body exists or not meets the following conditions: A+B+C+D > F-E, and a vehicle body satisfying the above conditions is defined as having production urgency.
8. The vehicle body production sequence scheduling method according to claim 6, characterized in that between S400 and S500 further comprises: s450, repeating the steps from S200 to S400 if the outbound queue is empty.
9. The vehicle body production sequence scheduling method according to claim 6, wherein the S500 step further comprises: and according to the inventory condition of the three-dimensional warehouse after the paint, when the number of the vehicle bodies with continuous warehouse-out conditions in the warehouse is insufficient, early warning prompt is carried out.
10. The vehicle body production sequence scheduling method according to claim 6, wherein the S500 step further comprises: when the vehicle body X needing to be delivered does not enter the post-paint storage three-dimensional warehouse, carrying out replacement adjustment, and modifying the information of the vehicle body Y which is the same as the X-chart number and has the largest planning sequence number in the post-paint storage three-dimensional warehouse, and replacing the X to deliver the vehicle body X to meet the general assembly production demand plan.
