Abstract

The invention relates to electronic devices that implement mathematical games, in particular games with numbers, and can be used as a training device for students to establish relationships between numbers in the process of playing. The invention solves the problem of increasing the entertaining game. The device contains a block 1 input answers, block 2 comparisons, time relay 6, generator 7 random sequence of codes, element AND-OR 8, clock generator 9, block 3 of information presentation, counter 4, encoder 10, element AND 5. The device provides more high interest, since it is possible to increase the number of guessed numbers to ten or more. In addition, if the player guesses the number in the number of attempts less than the calculated one for the selected field of numbers, and it takes less time than is set, then the player receives a "prize" - a musical melody played by the node of the musical signaling unit 3. 1 or .

The invention relates to electronic devices implementing math games in the game of numbers, and can be used in the learning process to enable students to establish ratios between numbers.

The purpose of the invention is to expand the didactic capabilities of the device.

The drawing shows a diagram of the training device.

The device contains a response input block 1, a comparison block 2, a training information presentation block 3, a counter, an AND 5 element, a time relay 6, a random code generator 7, an AND-OR 8 element, a clock 9 and an encoder 10. Block 1 contains information input unit 11 and control button 12, and block 3 - digital units 13 and sign 1 display and music signaling 15. The device operates as follows.

After connecting the device to an autonomous power source, in order to start the game, during which the unit manages to establish ratios between numbers, it is necessary to briefly press the control button 12. From this moment on one output of the time relay 6 sets the level of the logical unit, the positive front of which counter 4 the initial state, and at the output of the generator 7 of a random sequence of codes, a code is set for one of the numbers of the selected field of numbers, for example, from 0 to 9. The level of the logical unit at the input of the AND 5 element does not trigger the node of the musical signaling unit 3, since at the other input of the element 5, connected to the equality output of the comparing unit 2, the zero level remains. To the third input of the element 5 from the output of the encoder 10, the level of the logical unit is fed, since the counter h is located in the 0 initial state.

When choosing one of the possible answers, i.e. when entering information through the information input node 11, the output of the response input block 1 produces a bounce-free clocking signal by the level of a logical unit that, acting through the AND-OR 8 element, the input of block 3 permits operation

The digital indication node of the 3S unit and this node displays the number that was entered by node 11. The signal from the output of block 1 also allows the indication of characters by the node of the indicative display of block 3 and the generated comparison unit 2. Three situations are possible here: the indicator light is on, either: or. In the first and second cases, you must try again to guess the number. In the third case, the signal of the logical unit arrives at the second input of the And 5 element. If by this time the number of attempts to guess the number in one batch is less than the allowable one and selected by the encoder 10, then a high potential level remains at its output. Therefore, when an equal sign is received, the node of the musical signaling unit 3 reproduces an excerpt of the popular melody, which is the prize for winning the game. After the contacts of the information input unit 11 are opened, the potential of the zero level is established at the output of the response input unit 1, the digital and sign indicators of the block 3 are no longer illuminated. By the same difference, the state at the output of the counter changes. To make a new attempt to guess the number, it is necessary to press again one of the buttons of node 11 and, using the symbolic indication of block 3, continue the search for the number hidden by the electronic machine. The correct tactic of the player is to choose an average from the sex of the allowed numbers. After determining the location of the desired number, the remaining field of numbers is divided into approximately equal parts and the choice of an average number, and so on, until an equal sign is obtained. For example, when determining the number from the field of permissible values from 0 to 45 9, it is necessary to choose the number k or 5. Suppose that the number 5 is selected. Let, when the corresponding button of the node is pressed, the sign display unit of the block 3 shows the;; In this case, it is necessary to press the button corresponding to the number 2, and let the sign indicator show the sign. Now it is necessary to choose the number 3 or 4. For example, if when the button is closed, correspondingly.

This means that the next time you press the button for the number 3, a sign will be received. For a given field of admissible numbers, the maximum number of attempts to guess the number with the correct tactics is four.

The encoder 10 is constructed in such a way that its output is set to the level of a logical unit when the counter states, when the number of attempts to guess the number is less than the calculated number for the selected field of valid numbers, and when this number is exceeded, the output of the encoder 10 sets the logical zero level passing the signal from block 2 through element 5 to the node 15 of the musical signal of block 3. The appearance of a high logic level at the second output of relay 6 permits the passage of pulses from generator 9 through An AND-OR 8 input unit 3, causing the intermittent illumination of the digital display unit 3 which displays information about the number and state b counter. Such a glow of the indicators indicates that the batch is over and in order to continue the game it is necessary to briefly press the button 12 again. The intermittent luminescence of the indicators of unit 3 also allows not only to reduce the energy consumption from an independent power source, but also to draw attention to this electronic machine it is not occupied by training, then disconnect the power source.

The use of the device is possible for students to fix the device.
