Description

 The invention relates to automation and analog computing and can be used to build functional units of analog computers, means of automatic regulation and control, analog processors, etc.

 Relative selectors are known (see, for example, Fig. 4 in the book Volgin LI, Complementary Algebra and Modeling of Neural Structures. Tallinn: Academy of Sciences of Estonia, 1993), which contain n relators and provide the choice of the maximum of three (with n = 2 ) input analog signals.

 The reasons that impede the achievement of the technical result indicated below when using known relator selectors include limited functionality, due to the fact that the choice of the minimum or median of the three input analog signals is not ensured.

 The closest device of the same purpose to the claimed invention according to the totality of features is the relator selector adopted as a prototype (AS USSR 1262531, class G 06 G 7/25, 1986), which contains n relators and provides the choice of the maximum of three (for n = 2) input analog signals.

 The reasons that impede the achievement of the technical result indicated below when using the prototype include limited functionality due to the fact that the choice of the minimum or median of the three input analog signals is not ensured.

 The technical result of the invention is the expansion of functionality by providing the choice of the minimum, median or maximum of the three input analog signals.

 The specified technical result during the implementation of the invention is achieved by the fact that in a relator selector containing two relators, each of which contains a first comparator, the non-inverting and inverting inputs of which form the first and second inputs of the relator, the first inputs of the first, second and second inputs of the first relators are respectively the first, second and third information inputs of the relator selector, the feature is that a second comparator, connected invert, is introduced into each relator and non-inverting inputs to the first and third inputs of the relator, a logic element that reproduces the Equivalence operation, two make and two disconnect keys, the output of the second comparator connected to the control input of the second make and break keys, the inputs of which are the fourth and fifth inputs, respectively a relay, and the outputs are combined with the second input of the logic element connected to the first input and output, respectively, to the output of the first comparator and the control input of the first of the closing and opening keys, the inputs of which are connected respectively to the non-inverting and inverting inputs of the first comparator, and the outputs are combined and form the output of the relator, the third input of the first relay, connected by the output to the second input of the second relay, and the third input of the second relay, connected by the output to the output of the relator selectors are connected respectively to the second and first information inputs of the relator selector, the first and second tuning inputs of which are formed respectively by the combined four The worn and combined fifth inputs of the relators.

 The analysis of the prior art by the applicant, including a search by patent and scientific and technical sources of information, and the identification of sources containing information about analogues of the claimed invention, allowed to establish that the applicant did not find an analogue characterized by features identical to all the essential features of the claimed invention. The definition from the list of identified analogues of the prototype, as the closest in the set of essential features of the analogue, allowed to identify the set of essential distinguishing features in relation to the applicant’s technical result in the claimed device set forth in the claims. Therefore, the claimed invention meets the condition of "novelty."

To verify the compliance of the claimed invention with the condition "inventive step", the applicant conducted an additional search for known solutions in order to identify signs that match the distinctive features of the claimed device from the prototype. The search results showed that the claimed invention does not follow explicitly from the prior art for a specialist, since the prior art as determined by the applicant has not revealed the effect of the transformations provided for by the essential features of the claimed invention on the achievement of a technical result, in particular, the following transformations are not provided for by the claimed invention:
- addition of a known product by any known part (s) attached to it according to known rules to achieve a technical result in respect of which the effect of such additions is established;
- replacement of any part (s) of a known product with another known part to achieve a technical result, in respect of which the effect of such a replacement is established;
- the exclusion of any part (element) of the product with the simultaneous exclusion of the function due to its presence and the achievement of the usual result for such exclusion;
- an increase in the number of elements of the same type to enhance the technical result due to the presence in the tool of just such elements;
- the implementation of a known tool or part (s) of a known material to achieve a technical result due to the known properties of this material;
- creating a tool consisting of known parts, the choice of which and the connection between them are based on known rules, recommendations, and the technical result achieved in this case is due only to the known properties of the parts of this tool and the connections between them.

 The described invention is not based on a change in the quantitative characteristic (s), the presentation of such signs in relationship, or a change in its form. This refers to the case when the fact of the influence of each of these characteristics on the technical result is known and new values of these signs or their relationship could be obtained on the basis of known dependencies and patterns. Therefore, the claimed invention meets the condition of "inventive step".

 The drawing shows a diagram of the proposed relator selector.

The relator selector contains the first and second relators l ₁ and l ₂ . Each relator contains the first and second comparators 2 ₁ and 2 ₂ , the logic element 3, reproducing the operation "Equivalence", the first, second closing and the first, second disconnecting keys 4 ₁ , 4 ₂ and 5 ₁ , 5 ₂ , and non-inverting and inverting inputs comparator 2 _{1 are} connected respectively to the first and second inputs of the relator, the third input of which is formed by the non-inverting input of the comparator 2 ₂ connected to the inverting input and output, respectively, to the non-inverting input of the comparator 2 ₁ and the control input of the keys 4 ₂ and 5 ₂ , the inputs to of which are the fourth and fifth inputs of the relator, respectively, and the outputs are combined with the second input of element 3, connected by the first input and output to the output of the comparator 2 ₁ and the control input of the keys 4 ₁ and 5 ₁ , the inputs of which are connected respectively to the non-inverting and inverting inputs of the comparator 2 ₁ , and the outputs are combined and form the output of the relator. The second input of the relator 1 ₁ connected by the output to the second input of the relator 1 ₂ is the third information input of the relator selector, the first and second information inputs of which are formed respectively by the combined first input of the relator 1 ₁ , the third input of the relator 1 ₂ and the combined third input of the relator l ₁ , the first the input of the relator 1 ₂ connected by the output to the output of the relator selector, the first and second tuning inputs of which are formed respectively by the combined fourth and combined fifth inputs of the relators .

 The work of the proposed relational selector is as follows.

Вышеизложенные сведения позволяют сделать вывод, что предлагаемый реляторный селектор обладает более широкими по сравнению с прототипом функциональными возможностями, так как обеспечивает выбор минимального, медианного или максимального из трех входных аналоговых сигналов.At his first,. .., the third information and the first, second tuning inputs are respectively supplied analog signals (voltages) x ₁ , ..., x ₃ and the necessary control signals f ₁ , f ₂ ∈ {0,1}. If the signal at the third input of the relator is more or less than the signal at its first input, then key 4 is respectively closed or open, and key 5 is respectively open or closed. If at the second input of element 3 there is a logical "0" (logical "1") and the signal at the first input of the relator is more or less than the signal at its second input, then key 4 _{1 is} respectively open (closed) or closed (open), and key 5 _1, respectively, closed (open) or open (closed). Therefore, if at the second input of element 3 there is a logical "0" (logical "1"), then the relator will select at its output the smallest (largest) of the signals acting on its first and second inputs. Thus, the operation reproduced by the proposed selector is determined by the expression

The above information allows us to conclude that the proposed relator selector has a wider functionality compared to the prototype, as it provides the choice of the minimum, median or maximum of the three input analog signals.

Thus, the above information indicates the fulfillment of the following set of conditions when using the claimed device:
