Description
Technical field
The present invention relates to a kind ofly at OTP single-chip microcomputer storage inside bar code information, and utilize method and the device of the mcu resource inquiry bar code information of storing.
Background technology
For product information is carried out tracking and maintenance, the use of bar code is more and more general in high volume production process for modern enterprise, and common paster type bar code uses the most extensive because of its characteristics easy to use, with low cost.But also exist easily come off, the easy distinct disadvantage such as forgery.The user in use is easy to the phenomenon that is damaged and loses, thereby loses the effect of its finish message.The product that particularly needs compartmentalization to promote because the characteristics that paster type bar code is easily forged are easy to be utilized by the people, thereby is upset normal market order.
Summary of the invention
The purpose of this invention is to provide a kind of product bar code on-line storage and read method and device, use paster type bar code to have easily the defective that comes off, easily forges to overcome existing product.
For reaching above-mentioned purpose, the present invention proposes the thinking of utilizing OTP (One Time Progarmming) the single-chip microcomputer storage products bar code information in the product.In small household electrical appliance, used in a large number at present cheap OTP single-chip microcomputer, since be burnt to the program of OTP single-chip microcomputer and data have can not rewrite, can not lose, the characteristics of good confidentiality, if the burning of product bar code information in the OTP single-chip microcomputer, just in time can be solved the defective that common paster type bar code easily comes off, easily forges.But because the OTP single-chip microcomputer can only the single burning, and generally do not support online burning, although can adopt the method that when the burning control program, adds in advance bar code information, but when the complete installation of burning chip, be difficult to guarantee accurately corresponding with the bar code of actual product, bar code normally all is to confirm after the product test set installs into, so in advance the method for bar code information burning in chip do not had practical value, must want to realize online secondary programming.Given this, the invention provides following concrete technical scheme.
Product bar code on-line storage method of the present invention may further comprise the steps:
The online fever writes of OTP secondary is connected with product to be written, and connects a general barcode scanner for the online fever writes of OTP secondary;
Convert the bar code corresponding with described product to be written to binary code with general barcode scanner;
Binary code after the online fever writes of OTP secondary will be changed is burnt to the bar code stores district that reserves in the product to be written, and described bar code stores district is arranged in the ROM of OTP single-chip microcomputer.
Directly show surely numerical information because the small household electrical appliance of most of use single-chip microcomputer may differ, but button is generally still arranged as inputting interface, also have LED and indicate the interface as the user.Given this, the invention provides a kind of online read method of bar code that is applicable to this product, may further comprise the steps:
The input window of apparatus for reading of bar code is aimed at the LED lamp of the product that continues;
By the key-press input bar code reading order on the product that continues, after the single-chip microcomputer in the product that continues detects the bar code reading order, the data in the bar code stores district are sent to output port, the LED lamp that drives the described product that continues sends light signal;
Described apparatus for reading of bar code is converted to electric signal with the light signal that the LED lamp sends, and obtains bar code information after amplification, filtering, shaping, decoding, then is presented on the display screen of apparatus for reading of bar code.
The apparatus for reading of bar code that is used for the online read method of the said goods bar code, comprise the photosensitive Receiver, signal amplification and filter unit, shaping unit, decoding unit and the display unit that connect successively, photosensitive Receiver is converted to electric signal with the light signal that receives, electric signal after the conversion obtains bar code information after amplification, filtering, shaping, decoding, be presented on the display unit.
The present invention has following beneficial effect:
It is by reserving the bar code stores district in the OTP of product single-chip microcomputer, after the product test set installs into, bar code product is corresponding with barcode scanner converts binary code to, and the binary code after will changing with the online fever writes of OTP secondary again is burnt to the bar code stores district that reserves in the product.Since the bar code of burning in the OTP single-chip microcomputer have can not rewrite, can not lose, good confidentiality, therefore effectively solved existing product and used paster type bar code to have the defective that easily comes off, easily forges.
The present invention has solved the problem that the small household electrical appliance that does not have display screen shows product bar code under the prerequisite that does not increase cost of products.
