Description

1 11 The invention relates to telemechanics and provides the formation of a signal for the type of the Enable or Disable telecontrol command. Devices are known in which the signals of the command type are formed by separate buttons. In such devices, the transmission of the telecontrol command is divided into two stages — the selection of the telecontrol object (the assignment of the address of the controlled point, the group of objects and the telecontrol object in the group) and the subsequent formation of the telecontrol type ClJ. Closest to the invention is a device for. The selection of the remote control object address containing the keys according to the number of control objects 5 grouped together, the zero potential bus through the first contacts of the keys of each group connected in series to the corresponding inputs of the group address memory block, the zero potential bus through the serially connected links. The second contacts of the keys of the same control objects of each group are connected to the corresponding inputs of the memory of the address of the objects 2l. A disadvantage of the known device is the low information content, due to the need for additional command formation of the control body. The aim of the invention is to increase the information content of the device by combining the formation of the address of the telecontrol object and the telecontrol command (on, off). The goal is achieved by the fact that, in a device for generating remote control commands containing keys according to the number of control objects united into groups, a zero potential bus through successively connected first contacts of keys of each group is connected to the corresponding inputs of a group of address memory blocks, a zero potential bus through serially connected second contacts of the keys, the control objects of the same name of each group are connected to the corresponding inputs of the memory block of the address of the objects entered into each The key is the third contacts, dividing diodes, unequal element, prohibitors, pulse formers, I elements and UW55 outputs of the memory block of group 2 address. connected to the second inputs of the prohibition elements, the outputs of which are connected to the inputs of the pulse formers, the output of each of which is through the corresponding sections. The diodes and the third contacts are connected to the first inputs of the corresponding AND elements, the memory blocks of the address of the objects are connected to the second inputs of the AND elements, the outputs of which are connected to the inputs of the OR element. Thanks to this construction of the device, a new remote control key is provided the formation of not only the group number and the number of the remote control object in the group, but also the type of remote control corresponding to the new position of the key, whose position has changed. The drawing shows a block diagram of the proposed device. The device contains individual keys for each remote control object with two switching contacts with combined extreme terminals 1-1, ..., 4-1, 1-2, ..., 4-2 and one additional normally closed contact 1-3, .. 4-3. In the drawing, for example, four remote control keys are shown; the third additional contact in the drawing is shown disconnecting, however, a closing contact can be used equally in the device. To form the address of the controlled point, additional switching contacts (not shown) should be used. The principle of connecting the remote control keys in the device is as follows. The first switching contacts with combined extreme leads form successive chains, with the keys of all objects of the same group number being connected to the same chain. The outputs of the so-formed chains are connected between the grounded bus and the inputs of the memory block of the numbers of groups of remote control objects. The second switching contacts with combined extreme leads form successive chains, and the keys of the same object numbers in all groups are connected to the same chain. The outputs of the chains thus formed are connected between the grounded bus and the addresses of the memory block of the objects.

For the additional opening (closing) contacts of the keys, the first outputs of the contacts of the keys of the same group numbers and the second Q outputs of the contacts of the keys of the same number of remote control objects in all groups are combined.

In this example implementation of the device, the keys 1 and 2 control the objects of one, and the keys 3 and 4 of another group of remote control objects, the numbers of remote control objects related to keys 1 and 3, as well as keys 2 and 4 are the same. In accordance with the stated principle of making the connection, contacts 1-1 and 2-1 are connected in series and connected between the grounded busbar and one input of the block 5 of the memory of addresses of groups of remote control objects. Similarly, pins 3-1 and 4-1 are connected to another input of block 5. Consecutively connected contacts 1-2 and 3-2 are connected to one input, block 6 of memory - 30 addresses of control objects in a group. Similarly, pins 2-2 and 4-2 are connected to another input of block 6.. The outputs of block 5 are connected to the inputs of block 7 unequalities. Non-inverting inputs of prohibition elements 8 and 9 are connected to the outputs of block 7, and inverting inputs are connected to inputs of block 5. The outputs of elements 8 and 9 are connected to the inputs of drivers 10 and 11 of 40 pulses, the outputs of which are connected via separation diodes D Respectively to the outputs of contacts 1-3,2-2, and 3-3 and 4-3. Other conclusions of contacts 1-3 and 3-3 are combined and connected to one 45 input of the element I 12, and the other outputs of contacts 2-3 and 4-3 are combined and connected to one input of the And element, 13. The other inputs 12 and 13 are connected to the outputs of block 6, and their outputs to the 50 inputs of the element OR 14. The direct and inverse outputs 14 are connected to the first and second outputs of the device.

The number of memory elements in block 5, prohibition elements and pulse shapers 55 is set equal to the number of groups of remote control objects, and the number of memory elements in block 6,

AND elements and inputs at the OR element 14 is set equal to the number of remote control objects in one group, the number of separation diodes D is equal to the total number of keys.

The device works as follows.

When you change the position of any. the remote control key during the flight of contacts from one extreme position to another is broken one of the chains of the group number and one of the chains of the number of the object. At this time, pulses are generated, memorized by the individual memory elements of blocks 5 and 6. Block 7 only receives signals from block 5 and only outputs signals at the same time if no more than one signal 1 arrives at its inputs. This is necessary to protect the device from faults in the key chains and from incorrect actions of the operator. At the output of block 7, thus, at each instant of time, a

II 4 11 only one signal

A control unit may, for example, include a parallel code converter, which displays the state of all the memory elements of block 5, into a serial number and a counter-fixer of the number of signals 1 in the generated serial code. When more than one signal is entered into the counter, the code received from block 5 is blocked on AND elements 8 and 9.

The signals of block 7 are perceived by prohibition elements AND 8 and 9. After setting the new position of the control key, i.e. after the signal disappears at the input of the block 5, the output of the element 8 or 9 produces a signal 1, which arrives at the corresponding factors of the 10 and 11 pulses. The impulse from the imaging device, formed on the signal front from elements 8 or 9, is fed to the output of additional contacts of keys belonging to the group of objects punched by the block through dividing diodes D. Signals at the outputs of chains formed by additional contacts of keys correspond to the current state of keys This group of objects, including the new position of the key, whose position was changed. These signals are sent to elements 12 and 13 together with the signal 1 i from block 6. At one output of block 6, signal 1 is formed when the position of any control key changes, and the number of this output corresponds to the number of the object whose position has been changed. The output of the signal is And, from the nose of the control node to the object, a signal is generated that corresponds to the new position of the remote control. At the outputs of all the remaining second elements I, the signals O are set. Thus, at the outputs of the element OR 14, signals are generated corresponding to the position of the remote control key, whose position has been changed. It is important that the signals formed by the OR 14 element do not depend on the position of all the rest of the remote control keys and, therefore, they reflect the type of command being given. Accurately deciphering the type of the Enable or Disable command based on the output of the circuit OR 14 should be set according to the type (opening or closing) of the used auxiliary contact in the remote control keys. To transmit telecontrol commands, signals from blocks 6, 7 and element OR 14 are used. The construction of the proposed device provides for the generation of signals identifying the type of telecontrol using the same keys that specify the address of the telecontrol object, which, with a high control efficiency, simplifies the design , since it does not require installation of two keys for each managed object.
