SU520609A1 - Device for transmitting information - Google Patents

Description

The actual reading of this channel is stored there until a new one appears. As a result, it is possible that the substantial counts of each channel in the south channel will not only be received at the time of their arrival, but with some delay.

The proposed reading algorithm assumes polling channels through g channels (g is the number of unresolved channels between two respondents) with a call if the last countdown has already been written down, and the new one has not yet arrived, to the closest non-written down essentialFiviy counting from n {: ) drive two channels. Moreover, the ratio H (gi-i) should not be the whole number (where N is the total number of connected channels). The fulfillment of this condition ensures a consistent constant shift of the polled channels in order that there is no preference for polling only for / for certain channels.

FIG. 1 - block diagram of the device / u information transfer; in fig. 2 - cxQMa read block reader.

The device contains a control block I, a block 2 of forming an address-time part of sending channels, a block 3 that implements a zero-order extrapolation algorithm, and a link block 4.

Service signals are sent from the output of the radio telemetry system (RTS) to the input of block i, and the information part of the received message is sent to the input of block 3. The outputs of the unit 1 11o.t, are connected to the blocks 2, 3 and 4. The output of blocks 2 and 3 are connected to the corresponding inputs of the block 4.

The data on the uajsHMHH of a new substantial reading in each channel of the sensor and from the RAM EN11 is compressed information.

The operation of the circuit consists in that the information is processed by the algorithm zero-order and zero order in block 3, the device receives the 11-time-short part of the corresponding sensor channel and block 4 regularly outputs information in accordance with the proposed read algorithm. From the output of block 4, the compressed data input stream and the address-time parts of the message corresponding to the channels of the sensors are sent to the register.

The block of the link 4 transfers information and contains the first element OR 5, the element. AND 6, the trigger 7, the delay element 8, the second element OR), the group of elements W and the clock distributor I.

The device works as follows.

1 we look 6 - and dripped. If the last significant count is not described, then the trigger 7 is in state 1. since it was set to this state by the corresponding signal from the spares and, therefore, the group Element1-1) 1 And 10 was opened one by one

 I.mpu.che poll through the element OR 5 enters the entrance of the same elements AND, since the bits of the (in - p) -discharge binary word are permanently at the inputs, then the information and time-related parts of the word are output. channel, then at least one pulse from the outputs of the group of elements AND 0 through the element OR 9, delayed by the delay element 8, translates trigger 7 into the state O. The delay is intended so that in one polling cycle there are no two or more

words, since the inverse output of the trigger opens the element And 6, through which the polling pulse can go to the previous channel. Then, the next channel specified by the algorithm is polled.

I

If in the C-th channel the last substantial count was written off earlier, then the inverse output of the trigger 7 opens element I 6 of this channel and the impulse of the interrogation passes to the first element OR 5 of the i-1-I channel and passes the last significant count of the 8г1-th channel, if it was previously entered. In the event that in the i-th channel the last substantial count of 01 was entered earlier, the polling pulse of the 6th channel passes through the element 6 of the f. - 1st channel to the first element OR 5 2-2th channel (similarly

 channel) and depending on whether or not the last substantial reading of this channel is written off, outputs it or moves to the next previous channel and so on until the end of the t -th polling pulse ends or the closest one is not derived significant countdown. Next, a poll is performed on the next one specified by the channel down algorithm.

The dp transmission device allows you to simplify the adaptive telemetry system by reducing the amount of buffer memory used to equalize the compressed data stream.
