Description

one

The invention relates to a telegraph communication technique and can be used for remote control of a transmitting telegraph apparatus both when operating from a keyboard and when operating from a transmitter.

A device for remote control of a telegraph apparatus transmitter, comprising a transmitter launch control unit connected to a telegraph transmitter, as well as an information receiver, an AND element and an OR element, the first input of which is connected to a telegraph transmitter l

However, the known device has insufficient accuracy of blocking the transmitter of the telegraph apparatus.

The aim of the invention is to improve the accuracy of blocking the transmitter of the telegraph apparatus.

To do this, a counter and an information receiver, an AND element and an OR element, the first input of which is connected to the telegraph transmitter, are entered into the device for remote control of the telegraph apparatus, which contains the transmitter launch control unit connected to the telegraph apparatus transmitter. Stop, the input of which is connected to the input of the information receiver and the output of the OR element, to the second input of which the output of the counter is connected, the first input of which is connected to the output of the receiver For information, the input of the transmitter control unit starting and pervvi input AND gate, a second input and whose output is connected respectively to the output stop signal extracting unit and the second input of the counter.

15 The drawing shows the electrical circuit diagram of the proposed device for remote control of a telegraph transmitter.

20 The device contains a transmitter start-up control unit 1, a transmitter of a telegraph apparatus 2, an information output module 3, an AND 4 element, an OR 5 element, a counter 6, an allocation block 7

25 signals Stop and receiver 8 telegraph apparatus.

The device works as follows.

Information from the telegraph transmitter 2 via the element OR

5 enters the receiver 8 of the telegraph apparatus, where it is imprinted on the tape in order to control the operation of transmitter 2, and in block 7, the stop signal extraction unit 7, which generates a signal arriving during transmission of the stop parcel to one input of the element 4. Moreover, the information enters to the receiver 3 of information, which, in case of impossibility of reception (the memory of receiver 3 is full), generates a signal for the blocking of the telegraph apparatus arriving at the other input of the And 4 element. The And 4 element at a frequency and at the time of isolating the stop signal ylki generates signals to the count input of the counter 6 which after counting a certain number of signals (typically 1-4) outputs a signal which, via an OR gate 5 receives a telegraph receiver 8, retaining it in the stack. Since counter 6 generates a signal upon the arrival of a stop parcel, no distortion of information occurs.

The control of own transmission is constantly carried out by imprinting information on the tape of receiver 8, therefore, the operator can determine the moment of blocking and begin work when the block is removed from the desired character, thereby eliminating the repetition or omission of information. In the absence of a signal, the lock from receiver 3 of information arriving at the installation input of counter 6 is cleared, and the sajolm is allowed to pass through the telegraph device 2 through the OR 5 element of information. In automatic operation from the transmitter, the mechanism of the transmitter locks the keyboard of the telegraph transmitter. The transmitter operation is controlled by a signal.

{Block received from the receiver-. ka 3 information on the unit 1 control start-up transmitter. In the presence of this signal, the operation of the transmitter is prohibited, in the absence of -. is allowed.

The proposed device for remote control of a telegraph transmitter permits an increase in the accuracy of blocking the transmitter of the telegraph apparatus.
