Wherein, because each AGV has its own transportation task to the goods installation space and the maximum bearing capacity of each AGV are limited, therefore the AGV that carries out the goods that drops that actually selects is unable to confirm whether can accomplish the picking up and transporting of the goods that drops.
In implementation, after the AGV receives the cargo detection task, it can determine whether the AGV meets the condition of executing the cargo detection task, and specifically includes the following steps:
d10, acquiring cargo volume data and cargo weight data of the dropped cargo;
d20, acquiring actual installation conditions, and judging whether the loading conditions are met according to the cargo volume data, the cargo weight data and the actual installation conditions;

If detect the goods that drop, then pick up the goods to according to current position, compare AGV and self discharge station's distance and AGV and the distance of the station that drops the goods place, if AGV and self discharge station's distance is nearer, then carry out the transportation of self goods preferentially, if AGV and the distance of the station that drops the goods place are nearer, then transport the goods that drops preferentially.
In practice, if no dropped load is found in the overlapping area, the transport of the load is preferentially performed, and after the transport is completed, the AGV travels to the non-overlapping area, scans the non-overlapping area, and detects the dropped load.
In another embodiment of the present application, when the AGV does not perform the load detection task, a request signal is generated and the request signal is fed back to the AGV that has dropped the load, and the AGV that has dropped the load re-finds a new AGV. After the AGV that the AGV will not carry out the request signal feedback that produces drops the goods compares the actual transportation circuit diagram that obtains and self actual transportation circuit diagram, to there being the region of coincidence, the AGV carries out infrared scanning to surrounding environment in the transportation, judges whether there is the goods that drop in the transportation route. If the falling goods are detected, the road conditions are analyzed, whether the AGV can normally pass through the AGV under the premise of not touching the falling goods is judged, if the AGV can normally pass through the AGV under the premise of not touching the falling goods, the current route is kept to continue running, if the AGV can not normally pass through the AGV under the premise of not touching the falling goods, the route planning is conducted again based on the current position of the AGV, and a new route is selected to go forward.
