Postal code scanners, typically part of automated mail sorting systems, have a highly specialized structure that allows them to read, decode, and interpret postal code information from printed mail items. The design of these scanners can vary based on their intended use and the specific type of postal code technology being used, such as barcodes, QR codes, or alphanumeric characters. |
2.1 Key Components of Postal Code Scanners |
The core components of postal code scanners include: |
1.Imaging Sensors (Cameras or Laser Scanners): |
The scanner utilizes high-resolution imaging sensors, either in the form of cameras or laser-based systems, to capture an image of the postal code area on the mail item. These sensors are calibrated to detect barcodes, QR codes, or even printed alphanumeric postal codes. In more advanced systems, optical character recognition (OCR) is used to read printed postal codes. |
2.Decoding Software: |
Once the scanner captures the postal code, it needs to be decoded. Decoding software is responsible for interpreting the captured image or data from the sensor. The software recognizes the patterns in the barcode or the structure of the postal code and converts it into machine-readable information. OCR-based systems analyze the printed characters and interpret the alphanumeric code as a valid postal code. |
3.Data Processing Unit: |
After decoding, the data processing unit processes the postal code information to identify the correct sorting route or destination. The system cross-references the decoded postal code with a database or an internal routing system to determine the next step in the mail's journey. |
4.Output Mechanisms (Sorting Mechanisms): |
Once the postal code is identified and processed, the scanner communicates with the sorting system to direct the mail to the appropriate tray, bin, or conveyor belt. This can involve pneumatic tube systems, robotic arms, or belt-driven sorting machines. |
5.User Interface and Control Panel: |
Postal code scanners are often operated by postal workers or automated systems, and thus require an intuitive user interface. This control panel provides real-time feedback on the scanning and sorting process, showing any errors or issues with the postal code reading. |
