Изобретение относитс к эпектросв зи, может использоватьс в телеграфной аппаратуре и аппаратуре передачи данных.The invention relates to electrical communication, can be used in telegraph equipment and data transmission equipment.

Известно устройство дл приема дискретной информации приемной части электронного ствртстопного телеграфного аппарата, содержащее входной тритгер, стартстопный блок, формирователь тактовых импульсов и распределитель fljiA device for receiving discrete information of the receiving part of an electronic interlock telegraph apparatus is known, comprising an input tritger, a start / stop block, a clock generator, and a flji distributor.

Однако в этом устройстве правильный прием обеспечиваетс только при наличии стартовых и стоповых элементов в каждой кодовой комбинации.However, in this device, correct reception is ensured only when there are start and stop elements in each code pattern.

Наиболее близко к пpeдлaгaeмo y устройство дл приема дискретной информации, содержащее входной триггер, нулевой выход которого подключен к первому информационному входу распределител -накопител и к одному из входов первого элемента И, а еди ичный выход - к одному из входов второго элемента И, причем к другим входам элементов И подключен выход соответствующего разр да распределител -накопител , к тактовому вхопу которого подключен выход формировател тактовых импульсов, а также стартстопный блок 2J.Closest to the proposed device, y, is a device for receiving discrete information, containing an input trigger, the zero output of which is connected to the first information input of the accumulator distributor and to one of the inputs of the first element I, and the single output to one of the inputs of the second element I, and the other inputs of the AND elements are connected to the output of the corresponding bit of the distributor-accumulator, to the clock of which the output of the clock pulse generator is connected, as well as to the start-stop unit 2J.

Однако это устройство обеспечивает при-( ем дискретной информации стартстопным кодом , только при наличии стоповых элементов в каждой кодовой комбинации..,However, this device provides reception of discrete information with a start-stop code, only if there are stop elements in each code combination ..,

Цель изобретени - обеспечение приема Дискретной информации стартстопным кодом как при наличии, так и при отсутствии стопсмвых кодсжых элементов.The purpose of the invention is to provide reception of the Discrete information with a start-stop code both in the presence and in the absence of stop code elements.

Claims

To do this, the device for receiving discrete information contains an input trigger, the zero output of which is connected to the first information input of the accumulator distributor and to one of the inputs of the first element I, and the single output to one of the inputs of the second element I, and to other inputs of the elements And the output of the corresponding bit of the dispenser-accumulator is connected, to the clock input of which the output of the clock pulse generator is connected, as well as the start-stop unit, an additional AND element and an OR element are entered. a dispenser-dispenser through a series-connected additional element AND, an OR element and a start-stop unit connecting to the control inputs of the clock pulse generator and the dispenser-accumulator, to the erase input of which the subroutine is the output of the first element. And, with one (Mu 5 input element Or connected to the output of the second element And, and to the second information input of the distributor - a accumulator and to the second inputs of the start-stop unit and an additional element And - single output j input trigger. The drawing shows the structural electrical circuit of the proposed The device for receiving discrete information contains an input trigger 1, zero is the output of which is connected to the first information input of the distributor-accumulator 2 and to one of the inputs of the element And 3, and the unit output - to one of the inputs of the element And 4, and to the other inputs of the elements And 3, 4 is connected the output of the corresponding bit of the distributor - accumulator 2, to the clock input of which is connected the output of the forcing unit 5 clock pulses, an additional element And 7 and the element, IL AND 8. The output of the dispenser 2 of the dispenser through the series-connected element AND 7, the element of OR 8 and the start-stop unit 6 is connected to the control inputs of the 5 clock clocks puller and the distributor on1: opitel 2, to the erase input of which An output of an AND 3 element, and the output of an AND 4 element is connected to one input of the OR 8 element, and a second output of the 1 meter is connected to the second information input of the distributor-accumulator 2 and to the second inputs of the start-stop unit 6 and the And 7 element. discrete information as follows. The reception cycle of the first character starts at the start-topetop transition (and O); a received cobble (the values are recorded when the middle of the last code parcel is received, g, e. (fi +0.5) itt, where H is the elementary code of the primary code, and c is the duration of one load. At the same time, depending on the value of the parcel A signal appears at the output of the AND 3 or 4 element. If the postcode sends the current symbol, the AND 4 element skips the signal of establishing the true state of the start-stop unit 6, and; the device is set to stop, if the last parcel is currentless, the IZ element skips the signal to erase that combination in the distribution The LTE 2 and the start / stop unit 6 and the clock pulse shaper 5 remain in working condition. If the start cop is behind the last cop sending, from its midpoint the distributor drive 2 starts a new receive cycle, if the stop is sent, the signal from the drive distributor 2, corresponding in time to the reception of the code combination (ft + 1.5) tg, sets AND 7 and OR 8 to the initial state of the start-stop unit 6, and the entire device is set to a stop. Further reception is similar. The use of the proposed device for receiving discrete information ensures the reception of discrete information by a start-stop code both with and without stop elements, which allows to increase the speed of transmission and reception at the same wiring speed. Apparatus of the Invention A device for receiving discrete information containing an input trigger, the zero output of which is connected to the first information input of the accumulator distributor and to one of the inputs of the first element AND, and the single output to one of the inputs of the second element connected to the output of the corresponding bit of the razdelelitel-accumulator, the clock of which is connected to the output of the clock pulse generator, as well as the start-stop unit, so that with the aim of ensuring With discrete information, a start-stop code both with and without stop code elements, an additional AND element and an OR element are entered into it, and the output of the distributor-accumulator through the series-connected additional element And, the OR element and the start-stop unit is connected to the control inputs clock driver in the dispenser-accumulator, to the erase input of which the output of the first element AND is connected, and the output of the second element AND, and the second th data input of the accumulator and the distributor to the second inputs of the start-stop unit and the additional element and the output unit of the input trigger.
