Labelling of controlled objects

 

(57) Abstract:

Labelling refers to the tagging of controlled objects and is used for their identification. The method is based on the introduction of carrier identification signs, which represents the additive elements that are missing in the base material. The additive is introduced into the melt of the base material of the object and uniformly dissolved in the whole volume of the core material, and the combination of the composition and quantity of the elements forms the identification characteristics of the object. The method provides increased reliability of tagging objects, the possibility of marking the objects with the purpose of their differences during the whole period of operation.

The invention relates to the tagging of controlled objects and can be used to identify objects. (The problem of identification of multiple objects). In the area of application can include tagging of basic units of the car, and tagging different types of weapons and military equipment. In this case the label is unique and maintained throughout the period of operation of marked object.

There is a method of marking of controlled objects [1] by attaching to the object tag, material which avslutat beam of accelerated ions and rastrelivajut in phosphoric acid to form channels from the traces of ions. In these channels is injected radioactive substances with complex isotopic composition and half-life, big-time operation of the marked object, the amplitude spectrum scintillation outbreaks and individual is unique code labels in force random distribution volume label variable composition of radioactive substances.

Closest to the claimed method is a method of tagging controlled objects [2] by creating a label from a mixture of several elements with atomic numbers Z12, bonded solidified binder material, the volume of which entered radioactive substances. Effect of random location of radioactive substances in the volume label, a random proportion of mixture components and radioactive substances range of penetrative radiation on the surface of the label, consisting of x-ray radiation itself radioactive substances and x-ray fluorescence of the mixture will have a unique identification characteristic of the controlled object.

The main disadvantages of the method-prototype - the ability to eliminate labels with marked object and the dependence of the amplitude spectrum from the measuring detec the

The essence of the method consists in the introduction into the melt of the base material in the manufacture of marked object impurity additives that are missing in the base material.

Impurity additives introduced in small quantities, homogeneously dissolved in the base material and does not change its physical characteristics. The combination of the composition and quantity of the additives comprise a unique identification characteristic of the controlled object.

Unlike the prototype, the proposed method of identification characteristic is inherent in the whole volume of marked object remains unchanged during the entire life cycle of the object and cannot be destroyed or removed in any other way, except the object is destroyed.

Comparative analysis of the proposed solutions with the prototype indicates differences. Thus, the claimed method meets the criterion of "novelty."

When the analysis of the known technical solutions are not identified ways that have signs consistent with the distinctive features of the proposed method, which allows to make a conclusion about its compliance with the criterion of "inventive step".

As an example of the implementation of the proposed method is showing in the aluminum melt additives were introduced following elements: si, Zn, Fe, Ti, Ca. The measured range of x-ray fluorescence excited by sources55Fe and109Cd obtained from this sample, was registered as a model. For all subsequent measurements performed at different points in the sample and in different moments of time, the ratio of the line intensities of x-ray fluorescence introduced elements were within the limits of measurement accuracy unchanged, as well as received from these intensities concentrations of these elements. Thus, the qualitative and quantitative composition forms a unique label of this alloy, identification through comparison with a reference measurement.

Elemental spectral analysis can be done in different ways and sets of equipment for different geometry measurements. The results of the analysis can be entered and processed by the computer.

Elemental spectral analysis carried out by x-ray fluorescence or atomic emission analysis, which are characterized by high sensitivity and good reproducibility of the measurements, shows the appearance of 6 items additives and 3 levels of injected mass, it is possible to distinguish 36N.

The proposed method allows to produce a unique tagging of controlled objects and compared with the prototype improves the reliability of tagging as a carrier identifier becomes the whole mass of the test object. This unique characteristic remains unchanged during the entire time of operation of the facility and cannot be removed any other way, except the object is destroyed. Moreover, an advantage of the proposed method is the independence of the identification features from methods of analysis of the elemental composition.

The proposed method of creating an identification signs allows you to enter their classification and on this basis to ensure group marking of objects while maintaining the individual characteristics of each group object.
