Description

The invention relates to automation and computing and can be used to control data output with a punch.

The aim of the invention is to enhance the functionality of the device by providing control over the disappearance of clock pulses at various speeds of operation of the perforator.

FIG. 1 shows a block diagram of the device; in fig. 2 shows an example implementation of a control unit; in fig. 3 - the algorithm of the device.

The device contains the first key 1, the information register 2, the control unit 3, the mode setting unit 4, the parity generator 5, the control unit 6, the second key 7, the amplifier 8, the timer 9, the pulse generator 10.

The control unit 6 (Fig. 2} contains a multiplexer 11, a NOT element 12, a trigger 13, a micro-ROM ROM 14, an output register 15, a second pulse generator 16.

The device works as follows.

In accordance with the operation algorithm of the device (Fig. 3), with the receipt of the Record command, the control unit 6 generates a signal for turning on the perforator motor and a Request signal, in response to which a data bypass appears in the second group of device inputs and a Receive signal arriving to the input unit 6 controls. On this signal, the control unit resets the request signal and generates a signal. Writing information to the input of the first key 1. After that, the information register 2 stores the received data byte. With the arrival of the next punch sync signal. The reception of a code by the control unit 6 generates perforation and strobe perforation signals, which are performed by amplifier 8 to turn on the transport path perforation electromagnet and perforator code electromagnets of the bits in which the triggers of register 2 have a unit. In this case, the signal of the transport of the transport of the tape is reset.

With the arrival of the next sync pulse, the beginning of the perforator cycle, block 6, forms the signal Transport of tape transport. With the arrival of the clock pulse of the perforator, the control unit 6 clears the signal of the perforation gate, registers 2 is reset, and the request signal is again generated as a signal that it is necessary to receive the next data byte for perforation from the channel. The following data bytes are perforated in the same way as the algorithm described above.

The end of perforation of data according to the channel initiative is carried out if the channel has transmitted all data bytes. In this case, the signal is formed by the channel. End of data, which enters block 6. The latter in turn generates a signal.

0 Stop, which resets the Request signal and enters the channel.

The end of the perforation of data initiated by the perforators occurs at the end and break of the tape of the perforator, the appearance of units in those bits of information byte that are not used when outputting data. At the same time, the output of the device receives the corresponding signals

0 Data errors.

The equipment malfunction signal occurs when the perforator motor is not on, on command, when the motor is stopped or the perforator pulse generator 5 is out of operation during the output process. The control is performed by the control unit in accordance with the algorithm of FIG. 3. The monitored time interval ti (Fig. 3) is defined by timer 9, which is a serially connected binary-decimal counters, to the input of which a series of pulses are received from the generator 10. Four sequences are formed at the outputs of timer 9

5 pulses required to control the punch operation at appropriate perforation rates.

The control unit 6 during the operation analyzes the arrival of the clock signals.

0 of the perforator, and in the event of the loss of one of them and the deceleration of the speed of the electric motor, the equipment fails. Block 6 can be made in the form of a firmware automaton (Fig. 2). Input 5 multiplexer 11 serves to implement conditional transitions, ROM of micro-commands 14 serves for storing a set of micro-commands. The output register 15 is designed to store the current microcommand. The pulse generator 16 serves to synchronize the recording of the current microcommand to the output register 15. The trigger 13 serves to generate a signal that the automaton transitions from

5 of one state to another.

The information inputs of the multiplexer 11 are connected to the input signal buses of the control unit 6, i.e. signals, which are transitions from one state to another. In each state of the automaton, one of the input signal buses is connected to the lower address input of the ROM 14. The selection of the connected bus is made in accordance with the algorithm of the device operation.

The device has a higher performance. The introduction of a pulse generator and a timer into the device allows the condition control device to form the time position of the perforator sync pulses at different perforation rates for the control device.
