Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the following description, if suffixes such as "module", "part", or "unit" used to indicate elements are used only for the convenience of description of the present invention, they have no specific meaning by themselves. Thus, "module", "component" or "unit" may be used mixedly.
Fig. 1 is a flowchart of a parcel identification method according to an embodiment of the present invention. The parcel identification method provided by the embodiment of the invention is suitable for a parcel identification system. The package identification method comprises the following steps:
step S101, detecting whether the package enters an identification channel, wherein the identification channel is positioned above a tray;
in one feasible scheme, whether the package enters the identification channel is detected in the following specific mode: and detecting whether the package enters the identification channel by adopting an infrared scanning or radar scanning mode.
Preferably, the identification channel is a pipe-type channel perpendicular to the ground surface formed by stacking a plurality of air amplifiers. And a detection unit is arranged at the entrance of the identification channel and used for detecting whether the package enters the identification channel. The detection unit may be an infrared scanner, a radar scanner, or other detection device.
Step S102, when detecting that the parcel enters the identification channel, starting an air amplifier, and spraying airflow into the identification channel to enable the parcel in the channel to slowly descend;
in one possible scheme, the air flow is sprayed into the identification channel to enable the package in the channel to slowly descend, and the specific mode is as follows:
and the air flow is sprayed into the identification channel in an inclined upward direction, so that the package in the channel slowly descends.
The packages are transferred from top to bottom in the identification channel and finally reach the tray positioned right below the identification channel, and the bar code information of the packages needs to be identified by the bar code identifier when the packages reach the tray. If the parcel is in a free-falling state in the identification channel, the descending speed is extremely high, and the bar code identifier is difficult to identify in an extremely short time, so that when the parcel enters the identification channel, the air amplifier is controlled to spray air flow into the identification channel in an inclined upward direction, the parcel is slowly descended in the channel, and therefore, the bar code identifier has enough time to identify the bar code of the parcel.
In another possible scheme, the air flow is sprayed into the identification channel, so that the package in the channel slowly descends, and the specific mode is as follows:
when the bar code recognizer cannot read the bar code of the package initially, the air amplifier is controlled to regulate air flow, rotating air is generated inside the recognition channel, and the package is unfolded or turned over so that the bar code recognizer can read the hidden or shielded bar code on the package.
The identification channel is made up of a stack of multiple air amplifiers, so that each air amplifier can independently control the generated air flow, ultimately forming a whirlwind pattern.
In the scheme, when the bar code recognizer cannot initially read the bar code of the package, the air amplifier is controlled to adjust air pressure, rotating air is generated inside the recognition channel, and the package is unfolded or turned over so that the bar code recognizer reads the hidden or shielded bar code on the package.
Here, a time value may be preset, and when the barcode is not read to the barcode of the package within the preset time, it is determined that the barcode recognizer fails to initially read the information.
S103, controlling a bar code recognizer to read a bar code on the package in the recognition channel;
step S104, after the bar code of the package is successfully read, the air amplifier is closed;
after the bar code of the parcel is successfully read, the air amplifier is closed, and the specific mode is as follows:
the identification channel is formed by stacking a plurality of air amplifiers, and after the bar code of the package is successfully read, the air amplifiers are controlled to be gradually closed, so that the package can gently fall into the tray.
Each air amplifier is gradually closed, so that the descending speed of the packages can be buffered, the packages drop into the tray gently, and the packages are protected.
And step S105, enabling the packages to fall into a tray.
The package identification method provided by the embodiment slowly falls under the action of the air flow sprayed by the air amplifier, so that the bar code identifier has sufficient time to read the bar code of the package, and the package covered by the bar code is turned over, the folding soft package is unfolded and stretched under the action of the air flow, the covered and hidden bar code is exposed, so that the bar code identifier can successfully read the bar code, the problem of reading various types of packages is solved, and the identification efficiency of the package is greatly improved.
