The disadvantages of the analog device are:

- the lack of a network interface and the ability to directly interface with the equipment of the computer network and, as a result, the binding of the workplace of the operator-radio operator to the installation site of the device;

- lack of opportunities for direct input of information through the keyboard and manual control of manipulation circuits;

- the need to connect two power sources for the formation of bipolar telegraph parcels.

Closest to the proposed device is a domestic Morse code sensor P-020 [2], comprising an input unit (keyboard) connected to an information processing unit, the outputs of which are connected to an audio signaling unit and to a telegraph signal generator.

The disadvantages of the prototype device are:

- limiting the speed of information input;

- lack of ability to control and save the transmitted information;

- small size of the buffer storage device (16 characters);

- overwriting information in case of excess of the speed of inputting characters over the speed of transmission of characters in the line of manipulation;

- the need to connect two power sources for the formation of bipolar telegraph parcels.

The objective of the invention is the creation of a device for the automated transmission of Morse code signals using an information computer network.

The problem is achieved in that in a device for the automated transmission of Morse code signals containing an information input unit, an information processing unit, an audio signaling unit and a telegraph signal generator, the output of the information input unit being connected to the first input of the information processing unit, the first output of which is connected to the first input of the audible alarm unit, and the second output is connected to the first input of the telegraph signal generator, according to the invention, a signal converter is additionally introduced the interface interface and the manual manipulation unit, the first input-output of the interface signal converter being the input-output of the device for connecting to the computer network, and the second input-output of the signal converter of the interface by bidirectional communication is connected to the first input-output of the information processing unit, the second input the sound alarm unit is connected to the control output of the telegraph signal generator, and the first output of the sound alarm unit is the output of the device for connecting sound osproizvodyaschego device, wherein the first and second input-output generator telegraph signal are input-output device for connecting the positive and negative conductors lines manipulation, to the second input of the telegraph signal output connected to the first manual manipulation unit whose input is the input device.

Achievable technical result - the lack of binding of the device for automated signal transmission to the workplace of the operator-radio operator, the ability to work both in local mode when typing radiograms using the keyboard or manual telegraphy using the key, or in remote mode using the equipment of the computer network.

In FIG. 1 shows a functional diagram of the proposed device, where it is indicated: 1 - interface signal converter; 2 - input unit; 3 - information processing unit; 4 - block sound alarm; 5 - shaper telegraph signal; 6 - block manual manipulation. In FIG. 2 shows the algorithm for the operation of block 3.

The proposed device operates as follows. Block 1 receives control information and data from a networked workstation or other control equipment of an information-computer network via an Ethernet interface in a packet form. In this case, the electrical signals are level-coordinated and converted into a PHY physical-level microcircuit for further processing by the network interface controller (EMAC).

When the symbolic keys of block 2 (keyboard) are pressed, scan codes corresponding to the entered characters are generated at the output. Scan codes in the form of electrical signals arrive at the synchronous receiver of unit 3.

Block 3 can be implemented as a reprogrammable controller, the operation algorithm of which is shown in FIG. 2. The controller starts with block 3.1, where in the first program cycle the hardware is initialized, and in subsequent cycles, the hardware is set up and the current value of the tunable parameters and device status are checked. During the first check and with each subsequent change in the state of the hardware of the controller, a data set is generated for transmission over the network. Next, control is transferred to the integrated network interface controller (EMAC) - block 3.2.

The network interface controller controls the transmission of the packets generated by the program and the reception of packet data over the Ethernet network interface from block 1. If there is data to transmit, a packet is formed in accordance with the protocol of the application, network and transport interaction levels. The channel and physical level of interaction is provided by the signal converter interface 1.

Data of received packets is analyzed for the content of control information (block 3.3) and text information for transmission (block 3.4). If there is a configuration command or a status request in the received packet, the control information is processed by block 3.1, and the progress report is transmitted, as described previously. When receiving radiograms, the controller extracts information in the form of an ASCII code from the transport packet and transfers it to the general buffer 3.8. In the absence of network information, control is transferred to the universal synchronous-asynchronous transceiver (USART) - block 3.5, pre-configured in synchronous receiver mode to interact with the keyboard.

If there are accepted scan codes, they are analyzed for the contents of the control commands (block 3.6) and information symbols (block 3.7). If the received scan codes are a control command, then the corresponding information is transmitted for processing to block 3.1, the operation of which is described earlier. If there are accepted scan codes, the controller calculates the ASCII code of the character typed on the keyboard. Next, the character code enters the 3.8 common character buffer and control is transferred to the buffer work routine. If there are no characters in the transfer buffer, the processor returns to the beginning of the program.

The characters arriving at the 3.8 buffering block are lined up in a common queue, from which subsequently the first-in-first out (FIFO) selection is made. The ASCII code of the next selected character goes to the conversion routine - block 3.9.

In block 3.9, the ASCII code of the character is converted to a set of dots and dashes in accordance with the Morse code. In this case, according to the pre-made setting of the telegraphy speed (block 3.1), the durations of a single Morse code element and code sequence elements are calculated. The resulting set of dots and dashes is divided into individual packages in the form of logical levels 0 and 1, which are maintained on the output lines of the port (PIO) of the controller - block 3.10 - with the countdown of time intervals using timers built into the controller. The electrical manipulation thus obtained is transmitted from the output lines to the input of the telegraph signal generator 5.

The tone of the auditory control signal is adjusted using the “Tone” button connected to the input lines of port 3.10. In accordance with the settings made, unit 3.1 sets the built-in timer to change the state of the port 3.10 line with the tone frequency. The pulse tone tone signal generated on the output line of the port is transmitted to the input of the sound signaling unit 4.

The manual manipulation unit 6 is a telegraph key, to the general output of which a supply voltage is supplied. With the manual method of telegraphy, the operator makes successive presses and depressions of the lever of the telegraph key, as a result of which the manipulation sequences corresponding to the positions of the lever of the key at various times are formed from the supply voltage at the output terminals. Sequences are transmitted to the second input of the telegraph signal generator 5.

The inputs of the telegraph signal generator 5 can be implemented on a switch with several positions, on the input contacts of which the manipulation lines are connected. In accordance with the established position ABT. / KL. at the output of the switch, a manipulation sequence appears that controls the forming circuits of the telegraph joint. The signal leaving the control line serves to control the manipulation by controlling the input circuits of the audible signaling unit 4. The control manipulating sequence is transmitted via electronic keys to the LEDs of transistor optocouplers connected via a bridge circuit and control indicators output to the device case. The flashing of the control indicators indicates the presence of manipulation on the output circuits of the device, and the burning of indicators indicates the current state of the output circuits. The supply voltage supplied to the inputs of the shaper unit is supplied to the stabilizer, limiting the current and protecting the telegraph output circuits from current overload. A stabilized current is supplied to the input diagonal of the bridge from phototransistors. Phototransistors controlled by the light of the LEDs on the opposite shoulders of the bridge open in pairs, forming bipolar telegraph packages from the same supply voltage on the output diagonal of the bridge. Parcels are sent to the telegraph line connected to the terminals of the shaper “+ Manipulation Line” and “- Manipulation Line”.

At the input of the sound alarm unit 4, control control manipulation and a filling tone signal are received. After summing on the logic element "2I", the resulting manipulation signal passes through matching circuits, a filter and an acoustic amplifier with a volume control on a variable resistor. To implement auditory control of the transmitted manipulation, a sound reproducing device, for example, head phones or a headset, can be connected to the output circuits of block 4.

The device is implemented on the basis of radio-electronic components and materials manufactured by the industry. The interface signal converter block can be implemented on a transformer module, for example, Halo TG110, and a PHY physical layer microcircuit, for example, Micrel KS8001. Block 2 can be implemented on a keyboard panel with a PS / 2 interface, for example, TMS-M300 from SZX Industrial. The information processing unit can be performed on a 32-bit Atmel AT91SAM9XE512 microcontroller. The sound alarm unit can be performed on a 2I logic CMOS chip and an audio frequency amplifier IL34119D ADBK.431100.290-03 TU. The telegraph signal generator can be implemented on the ПГ2-21-2П4Н ОЮ0.360.068 TU biscuit switch, low-power transistors, LED indicators and optocouplers, for example, PB181S-R1 KENS.431156.091 TU. As a block of manual manipulation, a telegraph key can be used, for example, the telegraph key UIYAD.469419.005.
