A disadvantage of the known device is the complexity and, as a result, low reliability of operation.

The purpose of the invention is to simplify the device and increase its reliability.

The goal is achieved by the fact that the device for transmitting information containing a clock pulse generator, the output of which is connected to the first input of the first start-up unit, the second input of which is connected to the output of the first OR element through the first open contact of the operating mode change key The work is connected to the output of the source of a single signal, the second trigger unit, the output of which is connected to the input of the pulse distributor, the second element OR, the block receiving the call code dispatch In each information channel, a sensor, an OR element, a trigger and an And element, the sensor output is connected to the first input of the OR element, the output of which is connected to a single trigger input, the trigger output is connected to the first input of the And element, and triggers and information elements And all information channels connected to the corresponding inputs of the first and second elements OR respectively

The drawing shows the proposed device, the structural scheme.

A device for transmitting information consists of information channels 1, each of which includes a sensor 2,

0 element OR 3, trigger 4 and element AND 5, in addition, the device contains the first and second start blocks 6 and 7, the distributor 8 pulses, the first and second elements OR 9 and 10, the key 11 of the mode change

, work, 2 clock pulse generator, single signal source 13, pulse counter 14, AND-OR element 15, decryptor 16, dispatcher's call-code-receiving block 17, device output 18, C-OR element elements 19.

0 The device for transmitting information operates in three modes: sporadic information detection, cyclic information detection and monitoring.

The setting of the sporadic or cyclic information detection modes is performed using the key AND changing the operation mode. The control mode is set by sending the call code to the dispatcher. The mode of sporadic detection of information.

0 Through the opening contacts of the key 11 (the key position in this case is shown in the drawing), the output of the element OR 9 is connected to the second input of the starting block 6, the second output of which is connected to the reset input of the counter 14.

When any state of the sensor 2 changes, the pulse from the input of this sensor goes through the OR 3 element to the single input of the corresponding trigger 4 and translates it into the single state.

The signal from the single output of this trigger 4 prepares the corresponding element AND 5 for opening, and through the element OR 9 and the first break contact of the key 11, the start-up block b is opened. The pulses from the output of the generator 12 begin to flow to the summing first input of the counter. 14 pulses, in which the binary code of the number of recorded pulses is recorded. At the outputs of the decimator 16, signals appear sequentially in time, and the number of the output on which the signal appears is equal to the number of pulses recorded by the counter 14. Since each output of the decoder 16 is connected to the second input of the And 5 element and the zero input of the trigger 4 channel 1, whose number coincides with the output number of the decoder 16, then respectively, elements AND 5 are opened sequentially in time. When opening element 5 of channel 1, in which trigger 4 is in the unit position at the output of this element, AND 5 appears signal from the OR element U input unit 7 start, which starts to deliver pulses to the input of the pulse distributor 8. The first impulse arriving at the input of the distributor 8 sets it at the position where the signal appears at the second output and the signal disappears at the first output of the distributor 8. Due to the disappearance of the signal at the first output of the distributor 8, the start block 6 closes, and the counter 14 stops pulse generator 12.

In the counter, the binary code remains fixed, corresponding to the channel number I, in which the sensor 2 has changed its state and the trigger 4 is in the unit position. The signals from the outputs of the distributor 8 open successively the elements AND 19 of the element AND-OR 15 and the code recorded in the pulse counter 14, corresponding to the channel number 1 in which the information is recorded, is output in serial form to the output 18 of the device and further to the communication channel.

After the issuance of the code of the distributor 8 is completed, it returns to the zero position, while on the leading edge of the signal from the first output of the distributor 8, the starting unit 6 sends a pulse to the second output, coming through the second disconnecting contact of the key 11 to the zero reset input of the counter 14 and setting the latter to the zero position .

At the output of the decoder 16, the number of which corresponds to the number of channel 1 in which the information was recorded, the signal disappears and the falling edge of this signal, the trigger 4 of this channel 1 is set to zero position. After the time required to reset the counter 14 and the trigger

4 is opened at the first input of the startup unit 6. The device is ready to provide information about the state change by other sensors 2.

If two or more sensors 2 change their state at the same time or at a time interval shorter than the time required for the circuit to operate, the numbers of channels 1 having a lower numerical value are broadcast first to the output 18 of the device.

Cyclic information detection mode.

The position of the key 11 to change the mode of operation in this case is opposite to that shown in the drawing. Through closed

the closing contact of the key 11, the source 13 of a single signal is connected to the second input of the starting unit 6, the second output of which is disconnected from the zero input of the counter 14. Since the source 13 of the single signal is connected to the second input of the starting block 6,

 then this block passes the generator 12 pulses to the summing input of the counter 14, after filling the counter 14 is reset to the zero position and the filling cycle of the counter 14 begins again. At the outputs

5, decoder 16 signals appear successively in time. When the state changes, one of the sensors 2 triggers the corresponding trigger 4 and at the moment when the signal from the output of the decoder 16 in the next cycle opens the corresponding element AND 5, the starting block 6 will be stopped and outputted to the device output 18, channel number 1, in which recorded information. Further, since the reset circuit is broken, resetting the counter 14 to the zero position

 it will not be produced and counter 14 continues operation from the position in which it was left. Control mode To set the mode, the dispatcher sends the call code perceived by the call code reception unit 17, which generates a pulse that sets all the triggers 4 through the elements OR 3 to the single position. Depending on the position of the operating mode change key 11, similarly to the above, the output 18 of the device and the channel of communication is issued successively the codes of all channel numbers 1 or starting from the smallest, if the key 11 is in the position "sporadic detection of information, or from the channel number 1, element 5 of which was opened with a signal from you ode decoder 16 at the time of the trigger 4, if the key 11 in position nahodils "cyclic detection information.

The introduction of a pulse counter, a decoder, and an AND-OR element and new communications greatly simplifies the device and increases the reliability of its operation.
