Embodiment 2

[0075] A barcode automatic scanner, characterized in that, comprising:

[0076] Housing; proximity sensor; main controller; barcode reading module; wired communication interface module; where:

[0077] Housing; the housing is provided with a button to trigger the button to start; the housing is also provided with an indicator light; the indicator light has at least one LED light, which notifies the user through the change of color or flashing display: Trying to connect to an external device; connected to an external device; working; successful decoding, etc.

[0078] The proximity sensor is communicated with the main controller, and is set in the housing in parallel with the barcode reading module, emits infrared rays to the surface of the barcode, and receives the reflected infrared rays, and calculates the distance between the proximity sensor and the barcode. When the distance is within When within the range of the set distance, an activation signal is sent to the main con...

Embodiment 3

[0088] A bar code automatic scanning method is characterized in that, comprising the following steps:

[0089] S1: start, try to communicate with the external terminal.

[0090] S2: emit infrared rays to the surface of the barcode, and receive the reflected infrared rays, calculate the distance to the barcode, and send an activation signal when the distance is within the range of the set distance.

[0091] S3: After receiving the activation signal, send an instruction to read the barcode.

[0092] S4: The lens provides the complete barcode image to the image sensor through the reflection of light.

[0093] S5: Form a bright geometric shape on the surface of the barcode; for example, it can be a striped light spot when reading a one-dimensional barcode, and it can be a square light spot when reading a two-dimensional barcode.

[0094] S6: Convert and process the analog signal of the barcode image and output image frame data.

[0095] S7: apply the decoding algorithm to the out...

Abstract

The invention discloses an automatic barcode scanner. The automatic barcode scanner comprises a shell, a proximity sensor, a master controller, a barcode reading module and a wireless transmission module. By setting proximity sensor parameters, automatic barcode reading within the set distance range can be realized.

Description

technical field [0001] The invention relates to a barcode scanning and reading device and a scanning method, in particular to a barcode scanner and a scanning method. Background technique [0002] Barcode (referred to as barcode) can be divided into one-dimensional barcode and two-dimensional barcode. One-dimensional barcode is a mark composed of a set of regularly arranged bars, spaces and corresponding characters. "Bar" refers to the part with low reflectivity to light. "Void" refers to the part with high reflectivity to light, and the data composed of these bars and spaces expresses certain information. Two-dimensional barcode is a new generation of barcode technology that records data symbol information in a black and white rectangular matrix distributed in a plane (two-dimensional direction) according to certain rules; two-dimensional barcode can be divided into stacked two-dimensional barcode and Matrix 2D barcode. The stacked two-dimensional barcode is formed by sta...
