Description

This utility model relates to portable readers (scanners) designed to “capture” and decode various types of barcodes, including direct-printed character labels (SMPS) applied to individual parts and components of products, in order to identify and track them life cycle, as well as simultaneously recording the date, time and geographical coordinates of the scan location.

Countering the spread of counterfeit and counterfeit products is certainly one of the most acute and urgent problems for the consumer, the state and the entire business community. Losses of manufacturing companies, copyright holders and state budgets are estimated in billions of dollars. Damage to the health and well-being of millions of people is irreparable. The foundations of competitiveness, honest, law-abiding entrepreneurship are being undermined. An environment is forming for a shadow economy that nourishes corruption and terrorism.

In order to defeat this evil, consistent and coordinated actions are needed in the field of legislation and law enforcement practice, in the areas of management and social nutrition, education and public morality.

In particular: a) Counterfeit (pirated) products are products manufactured in violation of copyright, publishing or patent law (paragraph 2 of article 4 and paragraph 2 of article 40 of the Law of the Russian Federation of September 23, 1992 No. 3520-1 “ On trademarks, service marks and appellations of origin "). Counterfeit products prejudice the narrow fuppe of authors or copyright holders, and also contribute to under-receipt of taxes to the state budget, but expresses the interests of the population, since the price of products is significantly reduced.

As a result of the sale of counterfeit products, wider segments of the population gain access to high technology (for example, through the sale of pirated video audio cassettes or CDs). Such a phenomenon as counterfeiting is widespread throughout the world; suffice it to say that according to Interpol estimates, its trade in the world brings in revenues of about 500 billion euros per year.

b) Counterfeit products - is a fake of branded products, as well as products manufactured in violation of established sanitary and hygienic standards, sold under fake documents (Article 1 of the Federal Law dated 02.01.2000 No. 29-FZ “On Quality and Food Safety” ) Counterfeit products, in addition to damage to the budget and the owner of the brand, cause moral, material and physical damage to the population, since, as a rule, they are produced at minimal cost with violations of technology and established sanitary and hygienic standards. At the same time, such products may be counterfeit.

The last few years in Europe and the USA in a number of industries characterized by increased requirements for accounting, quality and reliability of parts, assemblies and products, SMPN technologies have been used more and more widely, containing the necessary information about the object in encoded form. SMPN is a universal tool for automated data collection and product protection both during production and during operation. Unlike ordinary character labels printed on paper or plastic and then pasted onto a controlled object, SMPS are applied directly to the surface of the product and can only be removed together with the material of this surface, thus being a reliable way to trace and control the product life cycle up to before disposal

Identification of SMPN at the facility (product, product, etc.) includes two stages - marking in the form of a bar code (one-dimensional or two-dimensional) and its reading.

When applying SMPN, two-dimensional coding (20 coding) is mainly used, which has a higher information capacity and noise immunity. The main difference between the two-dimensional code is that both orthogonal directions on the plane are used for information storage - vertical and horizontal. As a result, the capacity of a two-dimensional code can be hundreds of times greater than the capacity of a one-dimensional code in terms of the amount of stored information (for example, it is capable of storing several pages of text). If an external computer database is required when working with one-dimensional code, then in many cases the use of two-dimensional code allows you to abandon such a database, since the code capacity is sufficient to store complete information about the object. This is the qualitative difference between the two technologies.

In this regard, two-dimensional codes are indispensable, for example, in autonomous identification systems or, if necessary, the storage of complex characters of languages such as Japanese or Chinese. In addition, almost all modern technologies of two-dimensional codes, unlike one-dimensional codes, contain error correction tools, as a rule, based on the Reed-Solomon algorithm or other similar algorithms, and therefore guarantee greater reliability of data protection.

2D barcodes are portable information files of high density and capacity and provide access to large amounts of information without reference to an external database. That is, the barcoding technology 20 allows you to store all or most of its necessary information in the barcode itself. 20, the barcodes have a predominantly matrix form and do not use traditional barcodes / spaces to encode information. Instead of the standard technology for determining the stroke width, matrix barcodes are used to encode information of a yes-no or one-zero design (ie, on / off design). There are many varieties of 20 barcodes (e.g. P0P417, MaxiCode, Datamatrix).

The structure of the code supports the coding of the maximum number from 1000 to 2000 characters in one code with information density from 100 to 340 characters. Each code contains a start and finish group of bar codes that increase the height of the bar code.

Barcode readers 20, in contrast to ordinary barcode scanners, first capture their image, then analyze the resulting image and only then extract it and decode the barcode. Devices that use video analysis are necessary for efficient reading of matrix codes, but they can also read ordinary barcodes. Video analysis technology offers opportunities for reading signatures, optical character recognition, etc.

In fact, in terms of supported data volumes and functional capabilities, the two-dimensional coding technology takes an intermediate place between the technologies of one-dimensional barcodes and remote identification.

Initially, two-dimensional codes were developed for applications that do not provide enough space to accommodate a conventional bar code identifier.

The first application for such symbols was the packaging of medicines in healthcare. These packings are small in size and have little space for U symbolism. The electronics industry is also showing interest in high-density codes and two-dimensional codes due to the reduction in the size of elements and products.

One of the problems of reading and decoding SMPS is associated with significant technological difficulties both in terms of hardware solutions and software (software). For the scanner used to read SMPS, the main problem is to create illumination of the mark on an arbitrary surface, necessary to obtain an image of such quality that is necessary for reliable recognition. In terms of software, the problem is to increase the decoding ability of the analysis of heterogeneous "blurry" images. At the same time, the decoding process is strongly influenced by the strong dependence of the obtained electronic image on the state of the surface and external lighting.

So, it is widely known that for reading and decoding barcodes printed on various products, scanners of various modifications are used. In particular, a foreign scanner is known for reading and decoding applied barcodes, including in the form of SMGN Cognex DataMan 7500 http://www.cognex.com, http://www.micsys.ru/datamatrix new possibilities.php , a number of materials in Russian on request http://www.google.com.

Used known scanners traditionally have the following composition: a body with a trigger assembly (trigger), elements of the operator's light-sound information, such as a buzzer and several LEDs of various colors; the optical part, consisting of a two-lens lens and a lighting unit of the original design; hardware consisting of several printed circuits with various components (DSP processor, input / output devices, etc.), an optical sensor; software loaded into the Texas Instruments processor, consisting of general-purpose software (image capture, on / off LEDs of the lighting unit, input / output control) and special software for decoding frames of the captured image, which has unique decoding properties that ensure world-wide recognition.

From RU 96992 UI, 08.20.2000, a domestic-made scanner is known and widely used, which is a portable reader for reading and decoding barcodes, including the form of printed direct-printed character labels. The aforementioned scanner as a portable reader for decoding various types of bar codes, including direct-applied character labels, includes a housing with a trigger assembly, an optical part consisting of a lens and a lighting unit, hardware and software, such that the handle the case is located behind the case and smoothly passes into it, and the optical and hardware parts are made in such a way that the pulses of the target designation LEDs of the lighting unit of the optical part are not necessarily represent pulses in time with backlight LEDs and the optimal level of lighting is automatically selected by adjusting the current in the LED backlight, the light used for including LEDs with a narrow spectral emission range. However, this known scanner, which is the closest analogue of the inventive portable reader for decoding barcodes, does not simultaneously capture the date, time and geographical coordinates of the scan location.

A device for identifying cows is known (RF Patent No. 2423825, application No. 2009143334/21 dated November 26, 2009) for recognizing animal numbers, determining the location of the animal and directing them to the desired location, where the device contains a thermal imager — an optical-electronic measuring device that works in the infrared region of the electromagnetic spectrum, the thermal imager is connected to an electromagnetic control unit made in the form of a monoblock and containing a number recognition unit, a signal control unit, a live positioning unit tno, a memory unit and a pairing unit.

The device allows to increase the speed and accuracy of determining a candy animal, but does not allow to read and decode two-dimensional information labels, direct application, for example, on railway cars, pipelines, power lines with real-time fixation and geographical coordinates of the scan location.

Also known is a device in the form of a visitor control system (RF Patent No. 2378701, application No. 2008106710/09 of February 26, 2008), which relates to the field of visitor control systems and can be used in various rooms, controlling not only the stay of the monitored, but and determining their location.

The main disadvantages of this device are the impossibility of reading and decoding labels direct application as well as determining the geographical coordinates of the scan location.

So, the closest in technical essence is the well-known portable reader for decoding barcodes of various types, including symbol labels of direct application, described in the above RU 96992, 08/20/2000, however, as mentioned above, the known portable reader is not allows you to simultaneously record the date, time and geographic coordinates of the scan location.

The technical task is to expand the functionality of a portable reader that provides decoding of bar codes (bar codes) and provides at the same time fixing the date, time and coordinates of the scan location.

The stated technical task and the achieved technical result are achieved by a portable reader device declared as a utility model for decoding bar codes of various types, including symbol labels of direct application,

comprising a housing, a handle located behind it and smoothly passing into it, an optical part having a lighting unit and an apparatus part, the lighting unit comprising LEDs whose pulses do not coincide in time with the pulses of the LED backlight, and the optimal lighting level is selected (determined) automatically by adjusting the current in the backlight LEDs, LEDs were used for lighting, including those with a narrow spectral range of radiation, while the device contains an additional m module-receiver for determining the geographical coordinates of the scanning location by the signals of the navigation system with a built-in timer-controller, in which the real-time clock with a backup battery is built-in, which ensures the establishment of the date, time and place of scanning.

As a module for determining geographic coordinates from signals of a satellite navigation system, in particular, a GPS module (navigation system), a GSM module, WINCE, NET, as well as other well-known modules for determining geographic coordinates from signals of a navigation communication system, are used, “Global Navigation System (satellite ) GLONASS (RU 2365061, 08.20.2009), RU 2210788, 08.20.2003, RU 2402786, 10.27.2010, and other similar systems.

The following is the operation of the claimed portable reader.

Using a scanner with a built-in timer module for the current time and a device for obtaining the geographical coordinates of the area allows you to “bind” each barcode lecode not only to the date and time, but also to the geographical coordinates of the area where the product is located or is located at the time of scanning. For example, coordinates (latitude and longitude) with the accuracy provided by the satellite navigation system in the zone of its visibility. To obtain the date, time, geographical coordinates, the operator will scan the command mark, specially designed for this. Next, the operator expects a certain light and sound signals confirming the successful completion of the process, and the process ends with the recording of the received information in the scanner memory. The inclusion of additional information (coordinates + time / date) provides an additional controller with appropriate software that allows you to receive the current time, date and geographical coordinates at the time of scanning. The time and date values are provided by the real-time clock integrated in the controller and a backup battery that supplies the clock in case of power failure from the main source. Coordinates (latitude and longitude) with the accuracy provided by the satellite navigation system represent the receiver module for determining geographic coordinates from the signals of the satellite navigation system with a built-in timer for the current time.

This utility model is industrially applicable.

For example, when building a pipeline (gas / oil) with a long length or power lines, you can have information about each section of the pipeline or line - where, when and by whom (manufacturing plant, etc.) it was built. This information is useful and necessary in the process of operation and preventive measures.
