Preferably, the first weight is greater than the second weight, the first weight has a value of 1000 grams, and the second weight has a value of 200 grams.
In a specific embodiment, considering the case that N is 1, when information that the destination ports of the goods to be sorted on the adjacent trolley are consistent is obtained, judging whether the weight of the goods to be sorted on the previous trolley is greater than the first weight; if the weight of the goods to be sorted on the previous trolley is not more than the first weight, controlling two goods to be sorted on the adjacent trolley to sequentially descend to the destination grid; if the weight of the goods to be sorted carried by the previous trolley is larger than the first weight, the previous trolley is regarded as a target trolley, and meanwhile, whether the weight of the goods to be sorted on the next trolley is smaller than the set second weight is judged; if the weight of the goods to be sorted on the latter trolley is not less than the second weight, controlling the goods to be sorted on the adjacent trolley to sequentially drop the mesh grid; if the weight of the goods to be sorted on the latter trolley is smaller than the second weight, controlling the goods to be sorted on the target trolley to drop the destination grid, and then, not dropping the destination grid to drop the goods to be sorted on the latter trolley until the goods to be sorted reach the destination grid again; or controlling the goods to be sorted on the latter trolley to drop the destination lattice, and the goods to be sorted on the target trolley does not drop the destination lattice at the moment so as to drop the goods to be sorted when the goods to be sorted reach the destination lattice again.
Considering that when N is 2, the target trolley, namely the X+1 and the X+2 vehicles behind the X vehicle, all enter the error proofing judgment logic, and the weight of cargoes on the X, X +1 and the X+2 vehicles is correspondingly compared. After comparison, controlling the goods to be sorted on the X-number vehicle to drop the destination grid, wherein the goods on the vehicle meeting the conditions in the X+1 and the X+2 do not drop the destination grid at the moment and drop the goods to be re-arrived at the destination grid; or, the goods to be sorted on the X-number vehicle are controlled not to drop the destination lattice at the moment to drop the goods to be sorted on the X+1 and the X+2 when the goods to be sorted are to reach the destination lattice again, so that the light parts are guaranteed to be separated well, and meanwhile, the loss of sorting efficiency is reduced.
Therefore, based on the obtained average value of the time difference of the discharging grid openings of the goods to be sorted on the adjacent trolleys and considering that the N value is set too large, certain influence can be caused on the sorting efficiency, and therefore the comprehensive consideration of taking the N value to 3 is a preferable scheme for preventing rebound mistakes while considering the sorting efficiency.

the first issuing judging subunit based on the second weight is used for controlling the goods to be sorted on the N trolleys after the target trolley to sequentially descend the mesh grid if the weight of the goods to be sorted on the N trolleys after the target trolley is not less than the second weight;
and the second issuing judging subunit is used for controlling the goods to be sorted on the target trolley or the goods to be sorted on the N trolleys after the target trolley to be issued to the destination grid if the weight on the N trolleys after the target trolley is smaller than the second weight.
8. The control system for preventing a rebound error in an express delivery of claim 7, wherein the target cart determination subunit comprises:
the grid judgment module is used for judging whether the destination grid of the goods to be sorted on the continuous multiple trolleys is consistent;
the initial issuing judging module is used for controlling the goods to be sorted on the continuous multiple trolleys to descend corresponding destination grids if the destination grids of the goods to be sorted on the continuous multiple trolleys are inconsistent;
a judging module based on the first weight, configured to judge whether the weight of the goods to be sorted on each of the continuous multiple carts exceeds the first weight if the destination ports of the goods to be sorted on the continuous multiple carts are identical;
the issuing judging module is used for controlling the goods to be sorted on the continuous multiple trolleys to sequentially descend the same destination grid if the weight of the goods to be sorted on each trolley in the continuous multiple trolleys does not exceed the first weight;
and the target trolley determining module is used for searching out the trolley with the weight of the goods to be sorted, which is carried by the continuous plurality of trolleys and is greater than the first weight, as the target trolley if the weight of the goods to be sorted, which are on the trolley among the continuous plurality of trolleys, exceeds the first weight.
