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.

 Rank switches are known (see, for example, AS USSR 1693614, class G 06 G 7/25, 1991), each of which determines which of its three control inputs is affected by a median signal.

 The reason that impedes the achievement of the technical result indicated below when using known rank switches includes limited functionality due to the fact that the control input, which is affected by the minimum or maximum signal, is not determined.

 The closest device of the same purpose to the invention in terms of features is the rank switch adopted for the prototype (Fig. 1 in the description of the invention to A.S. USSR 1674168, class G 06 G 7/25, 1991), which contains three relays and determines which of its three control inputs is affected by the median signal.

 The reason that impedes the achievement of the technical result indicated below when using the prototype is limited functionality due to the fact that the control input, which is affected by the minimum or maximum signal, is not determined.

 The technical result of the invention is the expansion of functionality by ensuring the identification of one of the three control inputs, which is affected by a minimum, median or maximum signal.

 The specified technical result in the implementation of the invention is achieved by the fact that in a rank switch containing three relators, each of which contains a comparator connected by non-inverting and inverting inputs respectively to the first and second inputs of the relator, the first input of the first and first, second inputs of the third relator are connected respectively to the first and second, third control inputs of the rank switch, the peculiarity is that the first and second Boolean elements are introduced into each relator EXCLUSIVELY OR connected by the first inputs to the output of the comparator, and the first, ..., fourth keys connected by inputs and outputs, respectively, to the third, ..., sixth inputs and first, ..., fourth outputs of the relator, the control input of the first and second keys made respectively closing and opening, and the control input of the third and fourth keys, made respectively opening and closing, are connected respectively to the output of the first and the output of the second Boolean elements EXCLUSIVE OR, connected by the second inputs respectively To the first and second tuning inputs of the relator, the first and second tuning inputs of the three relators are connected respectively to the first and second tuning inputs of the rank switch, the first, second, and third information inputs of which are formed by the combined third, fifth, combined fourth, sixth inputs of the first and combined fourth, sixth inputs of the second relator, combined the first, third, combined second, fourth outputs of the third and combined first, third outputs of the second relator c are respectively the second, third and first outputs of the rank switch, the first, third and second control inputs of which are connected respectively to the first, second inputs of the second and second inputs of the first relators, the first, third and second, fourth outputs of the first relator are connected respectively with the fifth, third the inputs of the second relator and the fifth, third inputs of the third relator, connected by the fourth and sixth inputs respectively to the fourth and second outputs of the second relator.

 The analysis of the prior art, including a search by patent and scientific and technical sources of information, and the identification of sources containing information about analogues of the invention, made it possible to establish that there is no analogue characterized by features identical to all the essential features of the 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 us to identify the set of essential distinctive features perceived by the applicant in the claimed device set forth in the claims. Therefore, the invention meets the condition of "novelty."

To verify compliance of the invention with the condition "inventive step", the applicant conducted an additional search for known solutions to identify signs that match the distinctive features of the prototype of the claimed device. The search results showed that the invention does not follow explicitly from the prior art for a specialist, since the influence of the transformations provided for by the essential features of the invention on the achievement of a technical result is not revealed from the prior art as determined by the applicant, in particular, the invention does not provide for the following transformations:
- 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 invention is not based on a change in a quantitative characteristic (s), the presentation of such signs in relationship, or a change in its appearance. 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 invention meets the condition of "inventive step".

The first and second tuning inputs of the relators 1 ₁ ..., 1 _{3 are} connected respectively to the first and second tuning inputs of the rank switch, the first, second and third information inputs of which are formed respectively by the combined third, fifth, combined fourth, sixth inputs of the relator 1 ₁ and combined the fourth, sixth inputs of the relator 1 ₂ , the combined first, third, combined the second, fourth outputs of the relator 1 ₃ and the combined first, third outputs of the relator 1 ₂ are respectively the second, third and first outputs rank switch, the first, third and second control inputs of which are connected respectively to the combined first inputs of the relators l ₁ , 1 ₂ , the combined second inputs of the relators 1 ₂ , 1 ₃ and the combined second input of the relator l ₁ , the first input of the relator 1 ₃ , the first, third and the second, fourth outputs relator l ₁ are connected respectively to the fifth, third inputs relator 1 ₂ and the fifth, third inputs relator 1 ₃ connected fourth and sixth inputs respectively to the fourth and second outputs relator February _1.

где ext=min при f₁=1, f₂=0; ext=med при f₁=f₂=0; еxt=mах при f₁=0, f₂=1.The work of the proposed rank switch is as follows. On its first, ..., third control and first, ..., third information inputs, respectively, are given analog signals (voltages) x ₁ , ..., x ₃ and ₁ , ..., ₃ ; at its first, second tuning inputs, the necessary tuning signals f ₁ , f ₂ ∈ {0,1} are fixed respectively. If at the first adjusting input of the relator there is a logical “0” (logical “1”) and the signal at its first input is more or less than the signal at its second input, then key 4 _{1 is} respectively closed (open) or open (closed), and key 4 ₂ respectively open (closed) or closed (open). If at the second adjusting input of the relator there is a logical “0” (logical “1”) and the signal at its first input is more or less than the signal at its second input, then key 4 _{3 is} respectively open (closed) or closed (open), and key 4 _4, respectively, closed (open) or open (closed). Thus, the proposed rank switch will reproduce the operation

where ext = min with f ₁ = 1, f ₂ = 0; ext = med with f ₁ = f ₂ = 0; ext = max for f ₁ = 0, f ₂ = 1.

 The above information allows us to conclude that the proposed rank switch has wider functionality compared to the prototype, as it determines which of its three control inputs is affected by the minimum, median, or maximum signal.
