one

This invention relates to the display of sporadically varying information on a television screen in a form that is convenient for the operator.

A device for demonstrating a chess game on a display board comprising chess pieces with magnets, a chess board with sensitive elements, an initial installation block, a buffer register, an OR element, control nodes, a delay element, a register, an And element, a decoder and a single-shot J.

The disadvantages of the known device is its complexity, since the number of control nodes is equal to the number of boards. In addition, the complexity of the device increases as the number of concurrent batches increases.

Closest to the invention is a device for demonstrating a chess game, containing a check

matte figures with oscillatory circuits mounted in them, a chessboard, under each cell of which are placed sensors for positioning figures, connected to a converter of their signals into a digital code, random access memory, connected to the input of a converter, a generator of symbols, connected to the output of a random access memory, a control unit connected to a converter, a random access memory and a symbol generator; an image forming unit of chess fields connected control unit, the timing generators of the television connected to the control unit and mOsm blowing torus, whose inputs are connected with the character generator 20, forming staggered unit fields and the carrier frequency generator, and the output - to the antenna input standard television receivers 2.

However, this device has the disadvantage that in order to live tournaments with a large number of participants it is necessary to have several such devices operating in parallel, which leads to a complex system containing a large number of identical blocks.

The purpose of the invention is to simplify the device, allowing it to simultaneously display several batches.

The goal is achieved by the fact that in a device for demonstrating a chess game on television receivers, containing oscillatory circuits embedded in chess pieces, position sensors of the figures placed under each cell of the chessboard and connected to frequency converters in the code, the first block a memory connected to a symbol generator and a control unit connected to a symbol generator, a television clock generator and a chess field forming unit connected to modulators connected with a generator of carrier frequencies and a generator of a television clock signal, an adder and parallel code to serial converters are entered, the outputs of which are connected to the inputs of modulators whose outputs are connected to the input of the adder, the output of which is connected to the antenna inputs of television receivers, the first inputs of parallel code converters to the serial are connected to the symbol generator, the second inputs to the control unit associated with each of the frequency converters in the code, which are connected to the first block com memory, wherein the control unit comprises a series-connected pulse generator, an address register, the second memory unit, the first decoder and a second decoder connected to the counter zannomu communication with a frequency divider connected via a delay element to the trigger.

Claims (2)

With each personnel damping pulse of the television sync signal, the address register 19 (Fig. 2) of the control unit 9 (Fig. 1) is reset to the zero state (not shown). At the end of the frame damping pulse, the next cycle of interrogation of the sensors C for positioning the figures and forming the image of the characters of the figures begins. In accordance with the contents of address register 19 (Fig. 2), micro-instructions are read from the second memory block 20, which are converted by the first decoder 21 micro-instructions into control signals for the first memory block 7 (Fig. 1), the generator of 8 symbols of the chess formation block 11 fields of converters 15 and the second decoder 22 commands (Fig. 2). Initially, in accordance with the firmware, the line determining the direction of information flow on the bi-directional bus 16 (Fig. 1) is transferred to the zero state, which corresponds to the transmission of commands from the control unit 9 to the converters 6. Then the second decoder 22 (Fig. 2) transmits a command for polling the sensors of the location k of the figures (FIG. 1) in all the boards 5. After the time determined by the delay element 25 (FIG. 2), the RS flip-flop 26 sends a signal to begin transmission. Upon receipt of a response pulse from all converters 6 (Fig. 1), the RS flip-flop 26 (Fig. 2) is reset to the zero state, thereby stopping the transmission of the command. In this case, the flow direction information on bus 16 (Fig. 1) is translated to a single state. The transducers 6 interrogate the respective sensors and convert their output signals to a digital code, which is stored in the four-bit internal register of the transducer 6 of the next interrogation. Upon completion of the polling cycle, control unit 9 transmits a command to one of the converters 6 to transmit the figure name code to the first memory unit 7. At that, he transfers the information flow direction control line to the appropriate position, sends a clock pulse and waits for a response clock from the corresponding converter 6. When the command is completed, the selected converter 6 sets the figure code on four bus lines 1b and sends a synchronization pulse one by one out lines. The control unit 9 supplies the write-read of the first memory unit 7 with a write pulse. Thus, the code of FIG. 3, located on the cell of the board 5, is recorded in the corresponding cell of the first memory unit 7 divided by the number of boards. The gaming situation information on each board 5 is recorded in the corresponding segment of the first memory block 7. The control unit 9 then polls the next converter 6 and writes the shape code to another segment of the first memory block 7. When all the transducers 6 are polled, the control unit 9 transmits a command to poll the next sensors k boards 5-. All boards are queried simultaneously during one cycle. For a complete survey of chess boards 5, 64 such cycles are needed (according to the number of sensors). Commands of converters 6 are transmitted and their response signals are received during horizontal damping pulses. During the visible part of the lines, i.e. during the forward stroke of the line scan, information is read from the first block of the 7th frame and shows figures. During the first television line, the first decoder 21 micro. The commands (Fig. 2) of the control unit 9 (Fig. 1) are alternately polled memory cells in each segment that store information about the first horizontal of all the boards 5- The first cell of the first segment is polled. The four-bit code of the figure from the output of the first memory block 7 is fed to the input of the character generators, the output of which by the signal of the control block 9 is the 12-bit parallel code of the first line of the figure, which is fed via bus 17 to the inputs of the converters 15- Converters 15 are, for example, a shift register. According to the signal of the control unit 9, the output code of the character B is written to the first converter 15 Then the first cell of the second segment of the first memory block 7 is polled and the image code from the output of the 8 character generator is written to the second converter 15- After writing to all the converters 15, the control unit 9 goes to polling the second cells of all segments of the first memory block 7, etc. Control unit 9 controls the formation of video signals in such a way that they appear at the output of all converters 15 at the same time. These video signals, together with the signals of the generator 10 of the clock sync signal and the chess field formation unit 11, amplitude modulate the signals of the carrier generators 13 in the modulators 12. The generators 13 are tuned to the frequencies of different television channels, which allows combining the signals of all moduli tori in the adder 1 A and transfer the images of all the boards on a common cable. Selecting the appropriate channel in the television receivers 1, you can watch the progress of the games on any of the boards. After completing the image formation of the first horizontals of the chess boards, information is read from the next 8 memory cells of each segment of the first memory block 7 and the whole process repeats. Thus, the formation of a picture of all eight horizontals of chess boards takes place. The cycle ends at the start of the next frame damping pulse. The time sharing of the chessboard servicing allows reducing the equipment composition by using only one symbol generator, television clock signal generator and the image forming unit of the chess fields for servicing several chess boards to juice.
