The invention relates to telemechanics and provides for the generation of telecontrol signals in the form of an Enable or Disable command in stand-alone (using manual override of keys) and automatically (using commands in the form of a code issued from a computer) modes.

The purpose of the invention is to increase the information content of the device.

The drawing shows a block diagram of the device.

The device contains: the first switch of the first information channel 1, the switches of the second and fourth information channels 2-4j block 5 of the memory of addresses of groups of remote control objects, block 6 of the memory of the address of the object, block 7 of unequal values, first and second elements 8 and prohibition , the first and second shaper 10 and 11 pulses, the first and second elements And 12 and 13, the first element OR 1

multiplexers 15-18, second and third elements OR 1 9 and 20, a decoder. 21, triggers 22-33, the second switch 34 of the first information channel, developing diode diodes,

The introduction of multiplexers provides KOMivjyTauHro telecontrol commands either from switches (manual mode) or from the output of a computer in accordance with the state of the key entered. Operating mode.

The introduction of the elements OR provides the integration of the corresponding you-; multiplexer moves in one bus,

The introduction of the decoder ensures reception of the address of the control object to the corresponding trigger storage elements.

Introducing a group of triggers ensures that the addresses of the current objects are stored before the addresses of new objects are received.

The device works as follows

Manual operation. The switch 34 is set to Manual. At the same time, signals from the outputs of switches 1-4 pass through the multiplexers and pulses are generated, memorized by individual memory elements of blocks 5 and 6. Block 7 only receives signals from block 5 and outputs signals to the output if, simultaneously, its inputs no more than one sig0 arrives

1. It is necessary to protect the device from malfunctioning for the purpose of switches. The signals of block 7 are perceived by prohibition elements 8 and 9. After installing the new position of the switch, i.e. after the disappearance of the signal at the input of the block 5, the output of the element 8 shsh 9 forms a signal 1, which arrives at the corresponding shaper 10 and 11 pulses. The impulse from the forming unit 5 formed at the signal front from the elements 8 or 9 comes to the first mobile output of the first switch through the separation diodes 35,

The signals at the outputs of the multiplexers through the elements IL 19 and 20 are sent to elements 12 and 13 together with signals from block 6. At one output of block 6 signal 1 is formed when the position of any switch changes, and the number of this output corresponds to the number of the object whose position is changed, therefore, at the output of the AND element, related to this telecontrol object, a signal is formed corresponding to the new position of the switch. On the outputs of all the other second elb. the cops Pi is set to signal O.

Thus, at the outputs of the element OR 14, signals are formed corresponding to the position of the switch whose position has been changed.

Signals from 6 5 7 7 blocks and the OR 14 element are used to transmit telecontrol commands.

Automatic mode of operation. The switch 34 is set to Automatic. At the same time, multiplexers 15-18 switch command codes that are tapped into the corresponding triggers 22-33. In this case, the telecontrol codes on the computer tires go to the decoder 21 and to all the inputs of the flip-flops 22-33. In accordance with the code, the group of triggers of the corresponding information channel is selected and information on the object number is recorded in the selected channel. Recorded information is stored in triggers until a new command code arrives.

Selection and formation of a telecontrol command to other objects is carried out in a similar way.
