Description

Automatic idetifier of objects.

The utility model relates to means intended for automatic control of unauthorized interference and is intended to monitor the state of various intervention identification devices (DID). as well as to determine the authenticity of some controlled objects.

The development of a new direction of optical devices for identifying interference (seals, seals, signs of authenticity) has become possible thanks to the advent of automated devices for automatic monitoring of the status of such devices. The principle of operation of devices of this type is based on the registration of the optical image of the identification element of a seal, seal or sign of authenticity. In the general case, the optical image of the identification element is read either in transmitted optical radiation (RF patent No. 2124234 dated 04/18/96, IPC G09F 03/03). or in the reflected one (RF patent No. 2117989 dated 12/05/96, IPC G06K 09/58). When using reflected scattered radiation, the surface state of the identification element is analyzed. The uniqueness of the optical image can be determined either by the material itself, the texture of which, as a rule, is heterogeneous and creates a unique and unique pattern in the field of registration, or by forced and irreparable deformation of any of the elements, preferably with reflective properties.

As a prototype, an automatic object identifier was selected that contains an optical path formed by an output window made in the housing, a collecting lens, a diaphragm with an aperture and a light source, as well as a photo detector and an electric unit for processing, storing and comparing photodetector output signals (application for the grant of a patent of the Russian Federation No. 2000111879 dated 05/12/2000, published on 04/20/2002).

A device made on this principle can be successfully used for many types of optical TIDs, in which either a portion of the bonding body or a portion of the surface of the body with light-reflecting properties is used as an identification element, forming an optical image that is inevitably and irreversibly deformed during any attempt to covertly removal of DIV.

However, a large and diverse range of seals and seals themselves, and other objects that require reliable identification, requires the use of reading devices that are adaptable to recording various types and designs of such devices.

The problem is solved by that. that in automatic identification. comprising an optical path formed by an output window made in the housing. a collecting lens, a diaphragm with a hole and a light source, as well as a photo detector and an electric processing unit, storing and comparing the output signals of the photo detector, according to the claimed utility model, the identifier is equipped with a set of removable nozzles installed externally on the housing in the area of the exit window, in each of which hard positioning elements relative to} a part of the surface of the controlled object have their own configuration depending on the shape and size of the controlled area, and the source The lighting source in the optical path consists of several light-emitting elements operating at frequencies of the optical range that provide the maximum diffuse reflection coefficient. For the corresponding surface materials of the monitored area, when the ego is used, the identifier is supplemented by a control unit that ensures, in a given mode, the connection of one or several light-emitting elements depending on material of the surface of the controlled area and / or the reading algorithm of the optical image.

Thanks to this embodiment, it becomes possible multi-purpose use of the same device when selecting the appropriate nozzle and connecting the corresponding light-emitting elements.

The optical path can be performed in different ways. In the first embodiment, a diaphragm with an aperture is installed in the focal plane of the collecting lens between the indicated lens and a multi-element photodetector, and light-emitting elements are installed in the device’s body, providing different directions of illumination of the surface of the controlled area.

In another embodiment of the optical path, a diaphragm with a hole is installed in the focal plane of the collecting lens between the specified collecting lens and the exit window, and light-emitting elements are placed around the perimeter of the diaphragm.

As already indicated, the radiation frequencies of the light-emitting elements are selected in different parts of the spectrum of the optical range. So, for example, one of the light-emitting elements operates in the orange range. Another of the light emitting elements operates in the near infrared range.

The choice of a particular type of nozzle is also determined by the type of surface being monitored. In particular, the first type of removable nozzle is made with positioning elements along the angle and axis, providing a uniform installation of the housing

devices relative to the body of a traditional mastic seal and is intended for use of the device in identifying mastic seals. An orange light emitting element is used.

The second type of removable nozzle is made with positioning elements along the corner and perimeter relative to the central part of the diskette drive and is intended for use of the device in identifying computer diskettes.

The third type of removable nozzle is made with hard loio elements of positioning relative to mating elements extruded on the seal body with a tubular shape using a seal, and with an element for ensuring transverse positioning.

The fourth type of removable nozzle is made with positioning elements, correspondingly entering into the grooves on the controlled object.

In FIG. 1 and 2 schematically show two versions of the device. In Fig.Z. 4. 5. 6 shows various designs of interchangeable nozzles on the identifier housing.

The device comprises a housing 1 with an exit window 2. A collecting lens 3, an aperture 4 with an aperture, a multi-element photodetector 5 are placed inside the housing along the axis of the device. In addition, a lighting source consisting of several light-emitting elements - LEDs 6 is placed in the housing. In the first embodiment (Fig. 1) aperture 4 with an aperture is located in the focal plane of the lens 3 between the lens 3 and the photodetector 5. Light-emitting elements 6 are placed in the housing 1 as follows. to provide through the exit window 2 quasi-uniform illumination of the controlled surface. In the second embodiment (Fig. 2), the diaphragm 4 is placed in another focal plane of the collecting lens 3. The light-emitting elements 6 are mounted directly on the diaphragm 4 along its perimeter. In addition, the device includes a unit 7 for processing, storing and comparing the output signals of the photodetector 5 and a unit 8 for controlling light emitting elements 6. On the outer part of the end of the housing 1, elements 9 of the type of pins for installation with fixing various removable nozzles 10-13 are made.

The first type of removable nozzle 10 (FIG. 3) contains an angle positioning element (UB1, I) 14 and a positioning element (annular protrusion) 15 along the axis of the housing of the traditional mastic printing 16. When positioning the mastic printing, the positioning element 14 is included in the groove 17 of the printing housing 16.

floppy drive 20. Positioning element 18 when installing the floppy disk enters the groove 21.

The third type of removable nozzle (figure 5) contains a longitudinal positioning element (two cylindrical stops) 22 and a transverse positioning element (emphasis) 23 of a correspondingly deformed tubular hinged seal. The positioning element 22 is installed in extruded in the housing of the tubular seal nachy 25.

The fourth view of the removable nozzle 13 (Fig.6) contains positioning elements 26. accordingly included in the grooves on the controlled object.

The identifier works as follows.

Depending on the type of the controlled object, the appropriate nozzle is selected and installed on the end of the housing 1, fixed on pins 9 in the area of the output window 2. The nozzle with the help of positioning elements is uniformly installed relative to the controlled section of the controlled object. For example, when monitoring the state of mastic printing, the nozzle 10 is positioned along the angle and axis relative to the housing of the mastic printing 16, and each time using this device with the corresponding nozzle, uniform positioning will be observed. A switch placed on the working surface of the device (not shown) sets the operation mode of the device, which consists in selecting the light-emitting elements 6 and / or the sequence for their inclusion, which is set to block m. Blue 8. For example, when monitoring mastic printing, the orange LED turns on. because It has been experimentally established that for diffuse reflection from irregularities of the mastic material, this light provides the best reflection coefficient. For radiation materials, other radiation frequencies are selected.

Diffuse reflected radiation, passing through the hole in the nozzle, enters the optical path of the device and is registered by the photodetector 5. Then, in accordance with the developed control algorithm, the image is converted into a form convenient for storage and subsequent comparison using processing, memory, and comparison unit 7.

By using a set of nozzles with a single basic device, it was possible to expand the scope of its application and allowed to abandon the development of different types of identifiers for different designs of seals, seals and other objects, the identification of which must be carried out automatically.
