Description

The invention relates to automation and computer technology and can be used in specialized computing devices to simulate the process of moving a moving object (software), for example, in the conditions of functioning of space reconnaissance.

A device is known that contains k + 1 storage devices, a comparison unit, k digital-to-analog converters, a control circuit, a register, a counter, a selector, k formers of bell-shaped pulses, an adder, a voltage-current converter and a clock generator [1].

The disadvantage of this device is the relatively narrow functionality.

Closest to the claimed device is a device containing: a Poisson pulse flow generator, a controlled divider, seven AND elements, three NOT elements, three OR elements, two reversible counters, a random pulse flow sensor, a clock generator [2].

The disadvantage of the closest technical solution is the relatively narrow functionality that does not allow to simulate the process of moving a moving object.

The required technical result is the expansion of functionality by providing simulation of the process of moving a moving object.

The required technical result is achieved by the fact that in the device containing the first Poisson pulse generator, the first AND element, the second AND element, the OR element, the clock generator, the NOT element, the output of which is connected to the first input of the first AND element, the second Poisson pulse generator is introduced, the first counting trigger, the second counting trigger, while the output of the first Poisson pulse generator is connected to the first input of the OR element, the output of which is connected to the input of the first counting trigger, the output of which connected to the first input of the second AND element and the input of the NOT element, the output of the first AND element is connected to the second input of the OR element, the output of the second AND element is connected to the input of the clock pulse, the output of which is connected to the third input of the OR element, the output of the second Poisson pulse generator is connected to the input of the second counting trigger, the output of which is connected to the second inputs of the first and second element I.

An analysis of the scientific and technical literature showed that prior to the filing date of the application, there were no devices with the indicated set of features.

Therefore, the proposal meets the requirement of novelty.

In addition, the required technical result is achieved by the entire newly introduced set of essential features, which are not found in the well-known scientific and technical literature.

Therefore, the proposal meets the requirement of inventive step.

The drawing shows a structural diagram of a device for modeling the process of moving a moving object.

The device for modeling the process of moving a moving object contains a first generator 1 of Poisson pulses, a second generator 2 of Poisson pulses, a generator 3 of clock pulses, an OR element 4, a first element And 5, a second element And 9, the first counting trigger 6, the second counting trigger 8, element NOT 7, while the output of the first generator 1 of Poisson pulses is connected to the first input of the OR element 4, the output of which is connected to the input of the first counting trigger 6, the output of which is connected to the first input of the second element And 9 and the input element NOT 7, the output of which is connected to the first input of the first element And 5, the output of which is connected to the second input of the OR element 4, the output of the second element And 9 is connected to the input of the clock generator 3, the output of which is connected to the third input of the element OR 4, the output of the second the generator 2 of the Poisson pulses is connected to the input of the second counting trigger 8, the output of which is connected to the second inputs of the first element And 5 and the second element And 9.

A device for simulating the process of moving a moving object as follows.

When modeling the functioning of a moving object, it is assumed that in order to increase stealth by creating uncertainty about its location, the moving object periodically moves in the area of functioning. That is, in the process of functioning, a moving object can be in one of the states: {0 - stands, 1 - moves}.

To make it difficult to predict the state of a moving object in time, it is necessary to organize the process of changing positions so that the transition from one state to another is carried out at random times.

In this case, the time spent by the moving object in the parking lot at some point in the area of its deployment is advisable to distribute according to the exponential law. Distribution parameters are determined by the situation, for example, from the time of day.

Suppose that there is a reconnaissance system, for example, a space reconnaissance system designed to detect the location of software that can be in one of two states {0 - does not conduct reconnaissance to detect a moving object, 1 - conducts reconnaissance to detect a moving object}.

When modeling the reconnaissance process for detecting the location of software, the assumption is made that the moments of detection of software in time are distributed according to an exponential law. Distribution parameters are determined by the composition of the reconnaissance group, for example, by their number.

A change in the state of the software occurs at random times, and depending on the state of the intelligence system, an additional decision is made to change the current state of the software.

The algorithm for changing the state of software in the area of deployment during the functioning of the reconnaissance intelligence system can be represented as follows:

- if the software is installed and the intelligence system does not conduct reconnaissance to detect software, then the software is installed;

- if the software is installed and the intelligence system carries out reconnaissance to detect the software, then the software is installed;

- if the software moves and the reconnaissance system does not conduct reconnaissance to detect the software, then the software moves;

- if the software moves and the reconnaissance system carries out reconnaissance to detect the software, then the software is worth it;

- if the intelligence system stops conducting reconnaissance to detect software, then the software starts moving.

The specified algorithm for modeling the process of moving a moving object is implemented as follows.

In the initial state, the first counting trigger 6, the second counting trigger 8 are in a state of logical zero.

When the device is started from an external source, not shown in the drawing, in the first generator 1 of the Poisson pulses and the second generator 2 of the Poisson pulses, pulses occur, at random times corresponding to the Poisson distribution, which correspond to the exponential distribution of time intervals between state transitions. The pulse from the first generator 1 of the Poisson pulses passes through the element OR 4 and transfers the first countable trigger 6 from the zero state to the single state and vice versa. And the pulse from the second generator 2 of Poisson pulses transfers the second countable trigger 8 from the zero state to the single state and vice versa. The state of the first counting trigger 6 describes the state of the software, and the state of the second counting trigger 8 describes the state of the intelligence system.

Thus, thanks to the introduction of new elements and relationships, the required technical result is achieved - the expansion of functionality by modeling the process of moving a moving object.
