Description

The invention relates to systems for the transmission of electrical signals and power models to be used in shipbuilding for the communication of control and signaling bodies with a control of an object.

The purpose of the invention is to increase the reliability and speed of information transfer.

The drawing is a diagram of the device, i The device contains at the control point 1 counter 2, the first 3 and second 4 encoders, the first distributor 5 pulses, the keys 6, the transmitter 7, the generator 8 pulses, reception- | duck 9, the second distributor Yu pulses and indicators 11. At the test point 12, the device contained a repeater of 13 pulses, operating mechanisms 14, keys 15,

| 1 transmitter 16, the first 17 and second J8 pulse distributors, the first || 9 and the second 20 decoders, receive- | wk 21.

i The device also contains the first 2 and second 23 lines. Communication,: The device works as follows (|).

I The device action is built on the principle of time division signal.

Jjiob

 The separation transmitted in 1x time signals is carried out using a military counter of 2 pulses, I have ijjero several bits, decoded 3 and 4, distributors 5 and lO i iji repeater 1 3 pulses.

The state of counter 2 is changed by t using a generator of 8 pulses. Under certain conditions of counter 2 and repeater 13 pulses using decoders 3 and 4, the solution is transmitted and received from one or another channel.

Pulse repeater 13 has

As many outputs as ijx has counter 2, and its state at any time is the same as Counter state 2,

The decoders 3 and 4 of each of the points are identical, therefore with the help of their enabling signals to receive information at one point and transfer information at an OTHER point are formed at the same time, the signal transmission is 1UDED as follows.

When the closure of one of the keys 6 at the control station 1 (DP)

a single signal is fed to one of the inputs of the distributor 5. The logical structure of the distributor 5 is designed so that the signals of each key 6 pass to the transmitter 7 only under certain conditions of counter 2, then this signal is transmitted through the communication line 22 to the controlled point (KP ) 12, At the controlled point, through the receiver 21, a single signal is fed to the input of the distributor 18, controlled by the repeater 13 pulses through the decoder 20, the logical structure of the distributor 18 is constructed in such a way that the single signal ivshy at its input is passed to one of its outputs depending on the state of the follower 13 pulses. Since the state of the counter is 2 pulses and the repeater is 13 pulses in k; If the moment of time is the same, then the signal from each input key 6. can only pass to a specific output of the distributor 18 (KP) and, consequently, to a specific mechanism 14 Mechanisms 14 are used to turn on the control and signaling elements: contactors, magnetic starters, signal lamps and others

In a similar way, information is transmitted from the controlled point at which the keys 15 are locked to a control point where indicators 11 are turned on,

It is advisable to use the device on ships with a large distance of the cabin from the engine compartment, as well as on vessels with a lift cabin.

The application of the proposed device can significantly reduce the total number of cable lines, reduce the mass, volume and cost of cables used, reduce the cost / work of installing them and reduce the number of contacts and connectors for inter-instrumentation connections.
