Description
Technical field
The present invention relates to laser bar code identification research, particularly the multi-thread laser bar code reading device of a kind of omnidirectional and method.
Background technology
Bar-code reader is a kind of equipment of the information that comprises for bar code reading.Its identification accurately, data high input speed, and equipment is simple, cost is lower, in supermarket, numerous occasions such as library, warehouse obtain using more and more widely.Bar-code reader can be divided into rainbow optical bar code reader (also referred to as CCD scanner) and laser bar code reader according to light source difference.Rainbow optical bar code reader is to utilize photoelectric coupling (CCD) principle, and bar code printing pattern is carried out to imaging, and then decoding.Its advantage is: without rotating shaft, and motor, long service life; Low price.Laser bar code reader is to utilize laser diode as the single-line type scanner of light source, but it is all better than rainbow optical bar code reader in sweep velocity, scanning distance, scan sensitivity etc., and therefore main application in the market is laser bar code reader.
Laser bar code reader mainly contains rotary mirror type and two kinds of the mirrors of quivering.Rotary mirror type is to adopt high-speed motor to drive a prism group rotation, makes the single-point laser that diode sends become being aligned.The cost of manufacture of the mirror of quivering is lower than rotary mirror type, but the laser gun of this principle is difficult for raising sweep velocity, is generally 33 times/second, the highest can reaching 100 times/second, and the occasion that need to scan fast at some does not reach the requirement of application.
Publication number is that the Chinese patent of CN101916357A discloses a kind of laser bar code reading device and bar code reading method, processor and power module that this device comprises blue laser, deflecting mirror, swingable catoptron, optical collector, optical filtering, photelectric receiver, amplification treatment circuit, joins and blue laser is controlled with amplification treatment circuit.Its reading method is: the reception of scan light signal, the number conversion of scan light signal mode and collection, Fast Fourier Transform (FFT), removal high fdrequency component, Fourier inversion, the large law of use are carried out threshold calculations, according to threshold value, barcode signal carried out to binaryzation and decode according to all kinds of bar code standards.This method has following shortcoming: (1), though this method has reduced hardware configuration, recognition uses software algorithm, but this also causes recognition speed slower simultaneously, cannot carry out fast decoding.(2) this method still adopts the mirror of quivering, and sweep velocity is low, is not suitable for the occasion that need to scan fast.
Therefore, need to provide a kind of and distinguish speed soon and high laser bar code reading device and the recognition methods thereof of discrimination.
Summary of the invention
Fundamental purpose of the present invention is that the shortcoming that overcomes prior art, with not enough, provides a kind of omnidirectional multi-thread laser bar code reading device, and it has advantages of that recognition efficiency is high, and especially for beating Zou, breakage and reflecting bar code, recognition effect is better.The present invention also provides a kind of omnidirectional based on said apparatus multi-thread laser bar code reading method.
Object of the present invention realizes by following technical scheme: the multi-thread laser bar code reading device of a kind of omnidirectional, comprising:
