The invention relates to telemechanic and can be used in telemechanical systems for transmitting information from controlled objects.

A device for remote signaling is known, which contains contact sensors, elements AND, elements NOT a linear unit and a multi-wire communication line lj.

The disadvantage of this device is a large number of communication lines.

Closest to the proposed technical entity is a device for remote signaling, containing sensors, the output of each of which is connected to the first input of the corresponding element AND, the incoming b group of elements AND by the number of sensors, and the corresponding input of the element OR, the output of which is connected with the first input of the memory element, the output of the communication line is connected to the second input of the memory element and the combined second inputs of the AND elements of group 2.

The disadvantages of the known device are a large number of communication lines, the number of which increases in proportion to the number of sensors, and, consequently, low information content.

The purpose of the invention is to increase the information content by compacting signals.

The goal is achieved by the fact that in a device for remote signaling containing sensors, the output of each of which is connected to the first input of the corresponding element AND group and the corresponding input of the OR element, the output of which is connected to the memory input of the memory element, the output of the communication line is connected to the second input cell elements and combined second inputs of AND elements of the group; the element I, the element SHIII-NOT, the pulse generator, the frequency divider group and the frequency divider, the output of the pulse generator are connected to the combined inputs of the frequency dividers group, the outputs of the frequency dividers combined in group i are connected to the third inputs of the corresponding elements AND group, the output of the frequency divider and the output of the memory element are connected respectively to the first and second inputs of the AND element, the output of which and the outputs of the AND elements of the group are connected to the corresponding inputs of the element

OR NOT, the output of which is connected to the input of the communication line.

The drawing shows a block diagram of a device for remote signaling from two objects containing three sensors each.

The device contains sensors 1, a group of elements AND 2, an element OR 3, an element OR NOT 4, a generator of 5 pulses, a group of frequency dividers 6, a frequency divider 7, a memory element 8, a communication line 9, and an AND element 10.

When the state of any of the monitored object circuits changes, a signal is generated at the output of one of the sensors 1 connected to this circuit. The outputs of the sensors 1, corresponding to one type of generalized information for each object, are connected through the element OR 3 to the input of the memory element 8. Thus, when the state of a controllable object changes, that memory element 8 is triggered, to the Input of which sensors 1 are connected, corresponding to the type of generalized information that has arisen. The signal generated at the output of the memory element 8 permits the passage through the element 10 to the input of the element OR-NOT 4 pulse sequences with a divider 7 frequency, the period of which corresponds to the first object to be monitored. From the output of the element YLI-NOT 4, a sequence of pulses enters the link 9. If at this point in time another one or more sensors of the second object worked; then a superposition of pulses with periods T4 and T5 is formed in the link. This superposition arrives at the control point, where the transmitted sequences are separated and, with the help of the display facilities, the duty personnel are presented with information on the availability of summarized information on the corresponding objects. I

To view a specific circuit in which a change occurred, the attendant sends a poll signal in the form of a potential, which is fed through link 9 to the inputs of a group of elements AND 2 and to the second input of the memory element 8 of the called object. t, prohibiting the passage of pulses with a period T4 into the communication line and permitting the passage through the elements AND 2 to the input of the element OR-NOT 4 sequences of pulses with periods T1, T2, TZ corresponding to the chains that changed their state, In this case the communication link is transmitted from superposition passed to the input of OR-NO element 4 sequences where in turn, it can be sen layer with the sequence T5, the second object, if it has changed its state. This information arrives at the monitoring point, where the transmitted sequences are separated, and information on specific chains in which changes have occurred, with the help of display facilities, is presented to the personnel on duty. Upon receiving information, the duty officer shoots the interrogation signal of the first object and sends the interrogation signal of the second object.

The periods of pulses T1-T5, which are formed by dividers 6 and 7, should be 2, 3, 5, 7, 11 periods of impulses produced by the generator 5, respectively.
