Description

one

The invention relates to computing technology and is intended for use in computerized control systems and data acquisition and processing systems.

Devices for controlling the printing mechanism are known, containing an information source, the first and second outputs of which are connected to a pulse counter and a time counter, a print resolution block, the output of which is connected to the printing mechanism, and the inputs to the delay line and the enabling output of the printing mechanism, respectively.

The difference of the described device is that it contains a block for receiving code commands, a conversion block, an encryption block, a counter control block and an OR circuit, the third output of the information source through the block of receiving code commands connected to the corresponding inputs of the printing mechanism, the fourth output of the information source through the serially connected conversion unit, the counter control unit and the OR circuit connected to the input of the delay line, the outputs of the pulse counter and the time counter in pairs via the IL circuit And they are connected to the corresponding inputs of the printing mechanism, to the other inputs of which the outputs of the conversion unit are connected through an encryption unit, one

the output of the counter control unit is connected to a pulse counter, and the other is connected to a time counter, the synchronization output of which is connected to the synchronization input of the counter control unit. This allows a wider range of application of the device.

The drawing shows a functional diagram of the described device.

The device contains an information source 1, a code command receiving unit 2, a printing mechanism 3, a pulse counter 4, a time counter 5, a conversion unit b, an encryption unit 7, a counter control block 8, OR 9 schemes, OR 10 schemes, delay lines AND , a print resolution block 12 allowing output 22.

The device works as follows.

In accordance with a given program, from the source of discrete and impulse information 1, the code information is received via buses 13 into the code command receiving unit 2, which is designed to amplify and interrupt signals. From block 3, the code information on buses 14 is prepared at the input of printing mechapism 3. By the same program, the pulse information from source 1 via spikes 15 is fed to pulse counter 4, and the clock frequency from tires 16 to time counter 5, which controls the current test time. For the same program, bus 17 from source 1 to converter 6 of a discrete command into an impulse receives discrete information, both independently, as follows: accompanied by code and code information, nostu; Yush, and on tires 15 and 13, respectively, weppo. The commands that arrived in converter 6 are spaced in it in time by generating PMs along the leading and trailing edges of the discrete co, 1aid. From the converter 6, the pulse signals enter ciphering unit 7, from where encrypted groups on buses 18 are prepared at the input of non-proprietary mechanism 3, and to counter control unit 8, which by means of spike 19 gives permission to prepare time information for counter 5 through the schemes OR 16 on the spikes 20 at the entrance of the printing mechanism 3, or on the bus 21 gives permission to prepare for them the pulse information of the counter 4 through the schemes "OR 16 on the tires 20 of the printing mechanism 3. Simultaneously from block 8 to buses 19 and 21 through the scheme" OR 10 and lipia za7 epjkki 11 on one Signals are received from the inputs of the print resolution unit 12, indicating that information has been prepared at all inputs of the printing mechanism 3. To another input of block 12, bus 22 from printing mechapism 3 receives a signal of readiness to receive information. In the presence of sigals, odio-tempo and in both inputs of block 12, the latter issues a command of command 23 to receive and record information.
