Description

The invention relates to the automation of technological processes, is intended for use as a means of displaying information on mimic diagrams of the final positions and movements of the locking and regulating and similar actuators (W) having control bodies of their final states, and can be used in local) 1x and centralized monitoring and control systems in the gas, chemical, energy, and other sectors of the industry in those cases where it is not sufficient to signal the position of MI quantitative, but only superficially qualitative characterization of the state, carried out by simple devices when using lighting equipment for displaying information on dynamic mimics

The purpose of the invention is to increase the information content of the device by increasing the information provided to the operator about the operation of the actuating mechanism.

The drawing shows a functional diagram of the alarm device.

The device contains bus 1 and 2 positions IM, respectively, Closed and Open, light indicator 3 positions Closed, light indicators 4 and 5 positions Open, elements OR 6-9, elements AND 0 and 11, element OR NOT 12, triggers 13 and 14, 15 pulse generator, bus 16 Closed, bus 17 Open, bus 18 Stop, elements OR 19-21, elements OR 22-24, elements AND 25 and 26, counting trigger 27, distributor 28 pulses, bus 29 Reset elements AND 30-33 , trigger 34, bus 35 of information about the forward direction of movement of the working medium through the MI (forward direction), bus 36 of information about The direction of movement of the working medium through the MI (reverse direction).

The device works as follows.

The initial state of the device elements depends on the initial position of the MI, as well as on previously issued commands, for example, if the Close or Open commands were given, then the trigger 14 from one of its direct outputs causes a single logical

five

a signal, and vice versa - a zero signal, if previously the Stop command was given. The element OR NOT 12 produces a logical unit when the MI is not in one. Mr. of the extreme provisions.

Accepted for initial starting position when IM is completely closed. In this case, the bus 1 position Closed is given a logical unit to the element OR 6, which causes an equal glow of the 3 position indicator Closed. The other two indicators 4 and 5 are not light vehicles, since the bus 2 is in the Open position and the OR element is

0

NOT 12 gives zero signals.

Random commands Close, Stop and Reset do not cause a change in the position of the MI, nor the luminosity of indicators 3-5 When the Open command is issued over bus 17, trigger 3 switches to inverse state, triggers 14 and 27 go forward, at the same time (the chains Open, Close, Stop are not shown) the Open command to the drive is given. If the MI starts this command, then as soon as the sensor connected to the bus 1 position Closes the zero signal, the indicator

The 0 3 position goes out and the indicators 4 and 5 begin to flash intermittently, since the potential inputs to the inputs of the AND 11 element come from the OR-NOT 12 element, the trigger signal

0 open his side.

As soon as the MI is fully opened, at the output of the sensor connected to the 2 position Open bus, a single signal is output, which

through the OR element 19 through the counting input switches the trigger 27 to such a state that at its inverse output a single logic signal is formed, allowing passage of the pulses from the distributor 28 pulses to the OR elements 23 and 24 through the elements 30 and 31 or 32 and 33 provided that one of

If this signal is applied to the direct bus 35, then it is set to

trigger 34 is sent to the forward state and signals from the distributor 28 pulses to the elements OR 23 and 24 pass through the elements AND 30 and 31. At the same time, the intermittent illumination of the indicators 4 and 5 is transferred to the running light mode, which indicates a complete opening of the MI and movement in it of the material working environment in the forward direction. In this case, the running light on the indicator lights 4 and 5 of the Open position is achieved by performing the following glow sequence: first

the moment of time shines only on the indication- (5 Reset the luminescence of the indicator 4, the switch 4, then the light of the Tc is both indicated, and the indicator 5 lights up

torus 4 and 5, then only indicator 5 lights up and, finally, both indicators 4 and 5 are off.

If a single logical signal 20 is fed to the reverse directional bus 36, it sets the trigger 34 to the inverse state, and signals from the pulse distributor 28 to the OR elements 23 and 24 pass through the elements 32 and 33. At the same time, the intermittent luminescence of the indicators 4 and 5 is also switched to running mode.

If, during the movement of the MI towards its closure, by some way of doing the reverse sequential reason, bus 18 is fed to bus 18, namely: in the Stop mode, then the indicator of the 3rd time moment illuminates only the indicator 5, then both indicators 4 and 5 light up, then the tolling light stops, and the light indicators 4 and 5 are illuminated with a running light of the same directivity,

The indicator 4 and, finally, both of them went to the bus which has a single logiceni. The trigger 34 provides not only Memory, but also the clarity of the mutual exclusion of two signals.

Therefore, to translate it into an even glow on the busbar 29, a single control signal is applied that transfers the trigger 27 to the forward state. As a result, the transmission of pulses from the pulse distributor 28 to the OR 23 and 24 elements ceases and receive a single long-term potential signal that causes a smooth
