Известно многоканальное устройство приема сигналов, содержащее задающий генератор, выход которого подключен к входам синхронизации блока канальной обработки сигнала и блока групповой обработки сигнала, информа- ¹⁰ционные вход и выход которого соединены соответственно с информационным выходом и входом блока канальной обработки {1].Known multichannel signal receiving device comprising a master oscillator, whose output is connected to inputs of a synchronization channel signal processing unit and the group signal processing block ¹⁰ informa- translational input and output of which are connected respectively to data output and input channel processing unit {1].

Однако известное устройство обладает значительным временем приема и не обеспечивает обработку сигналов при произвольном распределении информационных скоростей в каналах.However, the known device has a significant reception time and does not provide signal processing for arbitrary distribution of information speeds in the channels.

Цель изобретения — сокращение времени приема и обеспечение возможности обработки сигналов при произвольном распределении информационных скоростей в каналах.The purpose of the invention is to reduce the time of reception and the possibility of processing signals with an arbitrary distribution of information speeds in the channels.

Для достижения цели в многоканальное устройство приема сигналов, содержащее зада ющий генератор, выход которого подключен к входам синхронизации блока канальной обработки сигнала и блока групповой обработки сигнала, информациошгые вход и выход которого соединены соответственно с информационными выходом и входом блока канальной обработки, введены формирователь приоритетов, компаратор, блок совпадения и фиксатор приоритета, причем адресный выход блока канальной обработки сигнала подключен к адресному входу формирователя приоритетов, выход которого соединен с первыми входами компаратора и фиксатора прио’5 ритетов, выход которого подключен к второму входу компаратора, выход которого соединен с первым входом блока совпадения, выход которого подключен к второму входу фиксатора приоритетов и входу записи блока ® групповой обработки сигнала, установочный выход которого соединен с третьим входом фиксатора приоритетов, при этом выход задающего генератора подключен к входу синхрони зации формирователя приоритетов, а второй вход блока совпадения соединен с выходом Запрос” блока, канальной обработки сигнала.To achieve the goal, a multichannel signal receiving device containing a master oscillator, the output of which is connected to the synchronization inputs of the channel signal processing unit and the group signal processing unit, the information input and output of which are connected respectively to the information output and the input of the channel processing unit, the priority driver is introduced, a comparator, a coincidence unit and a priority lock, and the address output of the channel signal processing unit is connected to the address input of the priority generator the output of which is connected to the first inputs of the comparator and priority lock 5, the output of which is connected to the second input of the comparator, the output of which is connected to the first input of the coincidence unit, the output of which is connected to the second input of the priority lock and the recording input of the group signal processing unit the output of which is connected to the third input of the priority lock, while the output of the master oscillator is connected to the synchronization input of the priority shaper, and the second input of the coincidence unit is connected to the "Block channel signal processing.

На чертеже представлена структурная электрическая схема предлагаемого устройства.The drawing shows a structural electrical diagram of the proposed device.

Устройство содержит задающий генератор 1, блок 2 канальной обработки сигнала, блок 3 групповой обработки сигнала, формирователь 4 приоритетов, компаратор 5, блок 6 совпадения и фиксатор 7 приоритетов.The device comprises a master oscillator 1, a channel signal processing unit 2, a group signal processing unit 3, a priority driver 4, a comparator 5, a matching unit 6, and a priority lock 7.

Устройство работает следующим образом, ί Блок 2 канальной обработки получает от обслуживаемых каналов сигналы, предназначенные для обработки, и фиксирует моменты смены информации в каждом канале. Сигнал смены информации появляется па выходе ’’Запрос” блока 2 канальной обработки и поступает на второй вход блока 6 совпадения.The device operates as follows, ί Channel processing unit 2 receives signals intended for processing from the served channels and fixes the moments of information change in each channel. The information change signal appears on the output of the ’’ Request ’for the channel processing unit 2 and is supplied to the second input of the coincidence unit 6.

Формирователь 4 приоритетов выдает приоритеты обслуживаемых каналов в соответствии с циклом их опроса, значение приоритета каждого канала зависит от скорости смены информации в канале и возрастает с увеличением последней.The shaper of 4 priorities gives out the priorities of the served channels in accordance with the cycle of their polling, the priority value of each channel depends on the rate of change of information in the channel and increases with the increase of the latter.

-I-I

Приоритет опрашиваемого канала в соответствии с адресом, приходящим с адресного выхода блока 2 канальной обработки, с выхода формирователя 4 приоритетов поступает на вход компаратора 5, на второй вход которого подается приоритет с выхода фиксатора 7 приоритетов. Если приоритет на первом входе компаратора 5 больше приоритета на его втором входе, то компаратор 5 разрешает с помощью блока б совпадения прохождение сигнала смены информации с выхода ’’Запрос” ' блока 2 канальной обработки на вход записи информации фиксатора 7 приоритетов.The priority of the interrogated channel in accordance with the address coming from the address output of the channel processing unit 2, from the output of the driver 4 priorities goes to the input of the comparator 5, the second input of which is given priority from the output of the latch 7 priorities. If the priority at the first input of the comparator 5 is higher than the priority at its second input, then the comparator 5 allows, using the match block b, the passage of the signal for changing the information from the ’’ Request ’output of the channel processing unit 2 to the input for recording information of the priority 7 latch.

Таким . образом, если приоритет опрашиваемого канала больше приоритета, записанного в фиксаторе 7 приоритетов, и при этом в опрашиваемом канале имела место смена информации, то при помощи сигнала с выхода блока 6 совпадения в фиксатор 7 приоритетов заносится приоритет опрашиваемого канала. Этот же сигнал с выхода блока 6 совпадения поступает на вход записи блока 3 групповой обработки, в котором фиксируется информация, приходящая от блока 2 канальной обработки, и сам этот сигнал. Если при опросе какого-либо последующего канала об наруживается, что в нем также имела место смена информации, и его приоритет выше приоритета, хранящегося в фиксаторе 7 приоритетов, то по команде разрешения от компаратора 5 сигнал с выхода блока 6 совпадения зафиксирует в блоке 3 групповой обработки информацию от этого нового канала с более высоким приоритетом, а в фик саторе 7 приоритетов зафиксируется приоритет этого канала.So. Thus, if the priority of the polled channel is higher than the priority recorded in the priority lock 7, and at the same time there was a change in information in the polled channel, then the priority of the polled channel is entered using the signal from the output of the match unit 6 into the priority lock 7. The same signal from the output of coincidence unit 6 is input to the recording input of group processing unit 3, in which information coming from channel processing unit 2 is recorded, and this signal itself. If during the interrogation of any subsequent channel it is revealed that there was also a change of information in it, and its priority is higher than the priority stored in the priority lock 7, then, by the resolution command from the comparator 5, the signal from the output of coincidence block 6 will record in group 3 processing information from this new channel with a higher priority, and the priority of this channel is fixed in the 7 priority lock.

Начало цикла работы блока 3 групповой обработки, т.е. начало обслуживания очеред₅ ного канала, характеризуется формированием импульса на выходе установки блока 3 групповой обработки, при помощи которого производится установка фиксатора 7 приоритетов в нулевое состояние.The beginning of the cycle of the block 3 group processing, i.e. the start of servicing the next _5th channel is characterized by the formation of a pulse at the output of the installation of group processing unit 3, with the help of which the latch of 7 priorities is set to zero.

Ю Если за цикл работы блока 3 групповой обработки смена информации произойдет в нескольких каналах, то первым будет обслужен канал с большим приоритетом, т.е. с большей скоростью смены информации.If the change of information occurs in several channels during the operation cycle of block 3 of the group processing, then the channel with the highest priority will be served first, i.e. with a higher rate of change of information.

1₅ При изменении информационной скорости в каком-либо канале изменяется и приоритет этого канала. Смена приоритетов производится в формирователе 4 приоритетов по командам, поступающим на его вход управ₂₀ ления.1 ₅ When changing the information speed in any channel, the priority of this channel also changes. Priorities are changed in the shaper of 4 priorities for the commands received at its control input _{20 of the} board.

В формирователе 4 приоритетов производится дешифрация команд, по которым по выбранному адресу канала с измененной информационной скоростью заносится новый ₂₅ приоритет.In the shaper of 4 priorities, commands are decrypted, according to which a new ₂₅ priority is entered at the selected channel address with a changed information speed.

Команды управления на формирователь 4 приоритетов подаются от некоторого внешнего управляющего устройства, например от пульта управления.The control commands to the shaper 4 priorities are served from some external control device, for example from the control panel.

Таким образом, приоритетная обработка ³⁰ сигналов позволяет создать многоканальное устройство обработки сигналов с любым распределением информационных скоростей и сократить время приема.Thus, priority signal processing ³⁰ allows you to create a multi-channel signal processing device with any distribution of information speeds and reduce the time of reception.

Claims

The invention relates to radio and can be used in information transmission systems for converting a stream of asynchronous messages arriving on parallel channels into a group stream with random channel separation. A multichannel signal receiving device is known, which contains a master oscillator, the output of which is connected to the synchronization inputs of a channel processing unit and a 5T1P block of signal processing, 1 information input and output of which is connected to an information output and an input of a channel processing unit 1. However, the known device has a sign reception time and does not provide signal processing at arbitrary resolution of information speeds in channels. The purpose of the invention is to reduce the reception time and enable signal processing with an arbitrary distribution of information speeds in the channels. To achieve the goal S, a multichannel network reception device, containing a task generator, the output of which is connected to the synchronization inputs of the channel processing unit of the group signal processing unit, the data output 1e input and output of which are connected to the information output 1 and the input of the channel processing unit, are entered priority shaper, comparator, match block and priority latch, with the address output of the channel signal processing unit connected to the address input of the formatter priority in, vhod which is connected to the first inputs of the comparator and priorities latch, the output of which is connected to the second input of the comparator, whose output is connected to a first input of a coincidence unit, an output of which is connected to the second input latch priorities and unit record entry grutshovoy signal processing FITTING n 1st. the output of which is connected to the third input of the priority latch, while the output of the master oscillator is connected to the input C1 of the priority driver, and the second input of the coincidence unit is connected to the output of the skgnal channel request processing. The drawing shows a structural electrical circuit of the proposed device. The device comprises a master oscillator 1, a channel signal processing unit 2, a group signal processing unit 3, a priority driver 4, a comparator 5, a match unit 6 and a priority lock 7. The device works as follows, i Channel processing unit 2 receives signals from the channels served for processing, and records the moments of informatics change in each channel. The information change signal appears on the output request of the channel processing unit 2 and is fed to the second input of the matching unit 6. Shaper 4 priorities gives priority to the served channels in accordance with the cycle of their survey, the priority value of each channel depends on the rate of change of information in the channel and increases with the increase of the latter. The priority of the polled channel in accordance with the address coming from the address output of the channel processing unit 2, from the output of the priority generator 4 is fed to the input of the comparator 5, to the second input of which priority is given to the output of the latch 7 at priorities. If the priority at the first input of the comparator 5 is greater than the priority at its second input, then the comparator 5 allows using the b block to match the information cMemi from the output of the output. Request channel processing block 2 to input information of the priority factor 7. Thus, if the priority of the channel being opted for is higher than the priority recorded in latch 7 of priorities, and there was a change of geformation in the polled channel, then the priority of the polled channel is entered with the help of the signal from the output of the block b in match 7. The same signal from the output of block 6 matches the input to the recording of block 3 of the group processing, which records the information coming from block 2 of channel processing, and the signal itself. If during the polling of a subsequent channel it is detected that there was also a change of information in it, and its priority is higher than the priority stored in priority fixer 7, then by a command from the comparator 5 from the output of block 6, will record in block 3 the group processing information from this new channel with a higher priority, and in ff4 a priority 7 priority will be recorded. The beginning of the operation of the block 3 group processing, i.e. The beginning of the service of the next channel is characterized by the formation of a pulse at the output of the installation of the group processing unit 3, by means of which the latch 7 of the priorities is set to the zero state. If, during the cycle of operation of block 3, the change of information occurs in several channels, then the channel with a high priority will be served first, i.e. with greater speed of changing information. When the information speed changes in any channel, the priority of this channel also changes. The change of priorities is made in the shaper of 4 priorities by the teams arriving at its control input. In the shaper 4 priorities, commands are decoded, according to which a new priority is entered at the selected channel address with a changed information rate. the controls to the priority shaper 4 are supplied from some external control device, for example from the control panel. Thus, priority processing of the setals allows creating a multi-channel signal processing device with any distribution of information speeds and reducing the reception time.
