Whereas the packages transported on the transport line in this embodiment are typically relatively large-sized packages or pieces, mixed transport of packages and pieces is also possible.
The ornament section 1 comprises a multi-section belt conveyor 301 and a first sensor, wherein the belt conveyor 301 can be replaced by other conveying equipment; the transportation speed of the multi-stage belt conveyor 301 in this embodiment can be adjusted to different modes, and the speed of the belt conveyor 301 is faster as it approaches the camera stage 2. The information labels are manually placed on the arranging section 1 one by one, and the information labels of the packages are ensured to face upwards, so that the camera section 2 accurately identifies the information labels on the packages.
The first sensor is installed at a position before entering the camera section 2, when a package is ready to enter the camera section 2, the first sensor detects and obtains the number of packages entering the camera section 2, if two or more packages enter the camera section 2 at the same time, the central control module can respectively control the working speeds of the multi-section belt transmission device 301 in the ornament section 1, then control the belt transmission device 301 far away from the camera section 2 to slow down the advancing speed or reduce the speed to zero, and the belt transmission device 301 closest to the camera section 2 continues to transport forwards, so that the distance between the packages is increased, and the shooting device of the camera section 2 can only shoot information labels of single packages, thereby improving the accuracy of package information identification.
The camera section 2 comprises a transport device, the shooting device and a second sensor; the transportation equipment used by the camera section 2 can also use the belt conveyor 301 to realize package transportation; the shooting device is arranged right above the transportation equipment, a parcel image of the parcel is obtained in a shooting mode, and an information tag of the parcel image is identified so as to obtain parcel information of the parcel; the package information comprises package names, package item types, package single numbers, delivery addresses, transport addresses and the like.
And the second sensor adopted by the camera section 2 is installed in front of the shooting device and is used for detecting whether a package passes or not, and when the second sensor detects that the package passes, the shooting device is triggered to shoot the package, so that an automatic effect is realized. The shooting device reports the shot package information to the central control module, the central control module extracts a package single number in the package information when receiving one package information, finds a target package discharging grid corresponding to the package single number from a pre-established package discharging time list according to the package single number and predicts the package discharging time, generates a corresponding grid instruction, and sends the corresponding grid instruction to the balance sorting device 302 corresponding to the target package discharging grid, so that each balance sorting device 302 of the package discharging section 3 performs package discharging operation on the matched package according to the grid instruction. The package number of each package, the bin number of the target package bin corresponding to each package, the number of the balance wheel sorting device 302 matched with each package bin, and the predicted package time corresponding to each package are stored in the package time list.
Referring to fig. 2 to 4, the lower piece section 3 includes a belt conveying device 301 and a balance wheel sorting device 302 that are freely combined, and in this embodiment, lower piece lattice openings may be arranged on both left and right sides of the balance wheel sorting device 302; the lower piece section 3 is further provided with a third sensor at the front end of each balance wheel sorting device 302, the third sensor being used for detecting whether a parcel passes or not; and the time when the package passes can be recorded as the actual arrival time of the package.
Referring to fig. 5, the method for determining whether the package reaches the target drop-out port is as follows:
assuming that a parcel needs to be delivered in the location of the target delivery bin number a, and a bin matches balance sorter 302A; when the third sensor of any balance wheel sorting device 302 on the transportation line detects that the package passes, the actual arrival time of the package passing is obtained, the predicted time for unloading all packages which are unloaded by the balance wheel sorting device 302 in the unloading time list is obtained, the predicted unloading time and the actual arrival time are compared, if the predicted unloading time is identical to the actual arrival time or the comparison difference value of the predicted unloading time and the actual arrival time is within a preset range, the current package is represented to have reached the corresponding target unloading port a, and then the balance wheel sorting device 302A is controlled to execute the unloading operation to sort the current package into the unloading port a. If the actual arrival time is different from all the predicted discharging time and the comparison difference value of the actual arrival time and the predicted discharging time exceeds the preset range, the fact that the package is not discharged at the current discharging lattice site is indicated, at this time, the balance wheel sorting device 302 corresponding to the current discharging lattice site does not execute the discharging operation, the package is enabled to continue to advance along the transportation direction, and the package is moved to the next discharging lattice site to execute the same comparison operation. If the parcel is not sorted by the balance sorting device 302 of all the drop-out pockets, then the relevant information representing the parcel is not recorded in the drop-out time list, meaning that the parcel may be an abnormal parcel falling off the conveyor or for other reasons, at which point the parcel flows to the end of the conveyor, merging the parcels together by the sorting device at the end of the conveyor; wherein the sorting device may be a balance sorting device 302.
Example two

Step S12: calculating the predicted unloading time when each package is transported to the matched target unloading grid according to the actual starting point time corresponding to the shooting of each package by the camera section 2 by combining the test data;
the method comprises the steps of obtaining service data in advance, obtaining package information of each package from the service data, and matching corresponding target package discharging ports for each package; the distance from the starting point to each discharging slot can be calculated according to the test starting point time, the test discharging time corresponding to each balance wheel sorting device 302 and the fixed transporting speed, and the distance is fixed, so long as the transporting speed is kept the same as the tested transporting speed in actual work, the predicted discharging time of each package can be calculated according to the actual starting point time of each package and the target discharging slot corresponding to each package.
Step S13: establishing a time list of the delivery according to the target delivery grid corresponding to each package and the predicted delivery time; in addition, the number of the balance sorting device 302 corresponding to the lower grid of each package can be added into the lower time list; and if other abnormal packages enter the conveying line in the middle, because the information of the abnormal packages is not in the time list of the unloading, the balance wheel sorting devices 302 corresponding to all the unloading lattice openings on the conveying line can not execute the unloading operation on the abnormal packages, and the influence of the temporary insertion of the abnormal packages on the packages conveyed in the normal sequence on the conveying line is avoided.
Step S2: when the grid port number corresponding to the third sensor where the package arrives currently is consistent with the target piece-discharging grid port corresponding to the package, acquiring the actual arrival time when the package arrives at the target piece-discharging grid port, comparing the actual arrival time with the predicted piece-discharging time, and if the comparison result meets the preset condition, controlling the balance wheel sorting device 302 corresponding to the current piece-discharging grid port to execute piece-discharging operation so that the package is transported to the corresponding piece-discharging grid port.
The third sensor in front of each balance wheel sorting device 302 is utilized to determine the transportation route of the package and the actual arrival time corresponding to the arrival of the package at the target drop-out pocket; the third sensor of this embodiment is a photoelectric sensor.
Referring to fig. 7, the target unloading slot and the predicted unloading time corresponding to the package in the unloading time list are called, when the package is transported to the target unloading slot, the actual arrival time of the package is recorded through a third sensor corresponding to the target unloading slot, the predicted unloading time is compared with the actual arrival time, and if the difference value of the predicted unloading time and the actual arrival time is zero or the difference value is within a preset range, the balance wheel sorting device 302 corresponding to the position is controlled to execute unloading operation; if the difference exceeds the preset range, the balance sorting device 302 does not perform the unloading operation, so that the package can be transported on the transportation line continuously.
The drop operation of each package in this embodiment is associated with pre-edited content in the drop time list, and the predicted drop time in the drop time list is associated with the speed of transportation of the drop section 3. The transport speed of the lower section 3 is supposed to be the same as the transport speed used in the test process, and is fixed. If the speed of the lower piece section changes, the speed needs to be measured again after the speed is changed.
