Description

The invention relates to signal devices and can be used in devices for automation and telemechanics, in particular for controlling the movement of street, rail, water and air transport.

A device for traffic control, a code block, two keys, two light sources and a voltage source is known.

The disadvantages of this device are its low reliability and durability due to surges, current through switches, light sources and voltage sources.

The closest to the present invention is a signaling device containing a voltage source, the first output of which is connected to the first input of the first light source and to the first input of the first key, and the second output is connected to the first input of the second light source and to the first input of the second key, the second input which is connected to the second input of the first key and the output of the generator of a single pulse, whose input is connected to the output of the pulse shaper, the first input of which is connected to the third input of the first key and to the first output the house of the code block, the second output of which is connected to the second input of the puller and with the third input of the second key, the output of which is connected to the output of the first key with the second input of the first AND second light sources 2U

The drawbacks of the device are its narrow functionality, which does not allow for the possibility of arbitrarily and independently from each other changing the order of switching the luminous sources of light sources. For example, in the case of forming zero voltage levels at both outputs of the code block, both keys turn out to be closed and light sources are connected in series with each other, as a result of which their normal illumination is absent (only half of the supply voltage is applied to each light source). In the case of the formation of unit levels on each output of the code block, both keys are simultaneously open, connected in series with each other and connected to a voltage source, resulting in a failure of both keys and a voltage source.

Purpose . invention - expansion

the functionality of the device and its reliability by eliminating the failure of the keys of the voltage source due to failures in the operation of the code block.

The goal is achieved by the fact that a device containing a voltage source, the first output of which is connected to the first input of the first light source and to the first input of the first key, and the second high; connected to the first input of the second light source and to the first input of the second key, the second input of which is connected to the second input of the first key and to the generator output of a single pulse, the first input of which is connected to the output of the pulse former, the first input of which is connected to the first output of the code block, the second the output of which is connected to the second input of the pulse former, three elements of a back-hold, a switch, an element are introduced; And and the element OR NOT, the first input of which is connected to the first input of the pulse generator and to the input of the first delay element, the output of which is connected to the third input of the first key and the first input of the AND element, the second input of which is connected to the third input of the second key and output the second delay element, the input of which is connected by the second input of the pulse generator and the second input of the OR-NOT element, the output of which is connected to the first control input of the switch and the input of the third delay element whose output is connected to the second m input, a single pulse generator, the output of which is connected to the third input of the element And the output of which is connected to the second control input of the switch, the first and second information inputs of which are connected respectively to the outputs of the first and second keys, and the first and second outputs are connected respectively to the second inputs first and second light sources.

FIG. 1 shows a block diagram of the device; in fig. 2 - articulation of the information inputs of the switch with its outputs at different logical voltage levels at its control inputs.

The device (Fig. 1) contains a code block 1, a pulse shaper, a single pulse generator 3, a voltage source 4, the first and second keys 5 and b, the first and second sources 7 and 8 of light, element 9 OR NOT, element 10 And the first, second and third elements 11-13 of the delay, the switch 14, the inputs and outputs of which are labeled 15-20.

The first output of the code block 1 is connected to the first inputs of the generator 2, element 9 and the input of element 11, the output of which is connected to the first input of element 10 and the third input of key 5, the first input of which is connected to the first input of source 7 and the first output of source 4, second output which is connected to the first input of the source 8 and the first input of the key 6, the third input of which is soy; it is connected with the second input of the element 10 and with the output of the element 12, the input of which is connected to the second output of the code block 1, the second input of the element 9 and VTORSh4 2, the output of which is connected to the first input of the generator 3, the second input of which is connected via the control element 13 to the output of the element 9 and to the first control input 19 of the commutator 14, the second control input 20 of which is connected to the output of the element 10, and the first information input 15 connected to the output KJDOcha 5, the second input of which is connected to the output of the generator 3, the third vz |: ode element 10 and the second input of the key €, the output of which is 16 connection; the second information input 16 of the switch 14, the First output 17 of which is connected to the second input of the source 7, and the second output 18 is connected to the second input of the source 8. The device works as follows. Let in the first cycle of the device operation at the outputs of code block 1 there are zero voltage levels, which through the delay elements 11 and 12 close the third input keys 5 and 6. At the output of element 9 OR NOT, like at the output of delay element 13, In a case there is a single voltage level, as a result of which the switch 14 is in a state that ensures that the sources 7 and 8 of the light from the source 4 are off, i.e. their glow is absent. :; But during the second cycle of operation of the device, the zero voltage level at both inputs of code block 1 is replaced by a single one, however, the unit voltage at the outputs of delay elements 11 and 12 will be generated only after ITj, resulting in 5 and 6 odTai5TCH at a given time to close by the third entrances. At the moment of changing the voltage on the outputs of code block 1, a pulse is formed at the output of the pulse generator 2, a trigger triggers a single pulse generator 3, and the output of element 9 OR-NOT generates a zero signal level that switches the 14th state to its information inputs and outputs are interconnected. Due to the fact that the output of the element 13 of the delay in time 1; a single voltage level is maintained, generated by the output of the generator 3 of a single pulse, the zero level pulse i voltage has a duration T. The signal of duration C maintains in a closed state the brakes 5 and 6 on the second INBO4, which were previously closed by zero voltage on the third entrances, and closes the third input, element 10 I. Due to the fact that the keys 5 and 7 are closed, and the first and second outputs; the switch 14 is interconnected, the sources 7 and 8 are connected in series with each other and connected in time U, to the voltage source 4. Upon termination of the output of the generator 3 of a single pulse, element 10 I opens, switching the switch 14 (Fig. 2o) to the state where the sources 7 and 8 of the light turned on were switched on 4 and in series, respectively, with 1 .6 and 5. No signal at the output of the generator 3, leads to the opening of the keys 5 and 6, i.e. to the connection of the sources 8 and 7 of the light to the source 4 of the voltage. Since the total voltage of source 4 is now applied to the light sources 7 and 8, their luminosity quickly reaches the nominal value. In the third cycle of operation of the device, at both outputs of code block 1, levels of zero, voltage are formed, and a single level of voltage at the output of element 9 is formed as a result of this OR NOT switches xilmutator 14 into a state in which sources 7 and 8 of the light are disconnected from source 4 voltage, their glow ceases. The operation of the other component parts of the device in this cycle of operation is not significant, since the light sources are disconnected from the voltage source 4. In the fourth cycle of operation, a single voltage level is formed at the first output of the code block 1 (while maintaining the zero voltage at the second output). In this case, the device operates in the same way as in the second cycle of operation, owing to the fact that the output of delay element 12 maintains a zero voltage level, the key remains closed during the entire cycle time and the unit signal at the output of element 10 does not is formed. Therefore, after preheating the filaments of both sources for the time t, switching of switch 14 does not occur (it maintains the state shown in Fig. 2 (J); opening the key 5 causes the light source 7 to be bypassed, and the brightness of the light source 8 reaches nominal value, since the key 5 is connected to it through a parallel-connected open source and the light source 7 is applied to the voltage of source 4 (the resistance of the private key 6 is large and does not shunt the light source 8.) Eni only light source 8 light.

The fifth cycle of operation of the device is similar to the above-described third cycle of operation, when the illumination of both light sources is absent.

The sixth cycle of operation of the proposed device, when the voltage of the logical unit of the phon1 is only at the second output of the code block, is similar to the fourth cycle described above, but in this case the key 6 is opened, as a result of which the light source 7 lights up.

In the seventh cycle of operation at the first and second outputs of code block 1, the levels of single and zero voltages are changed. The operation of the device is similar to the above fourth cycle of operation. The difference lies in the fact that since in the previous cycle of operation at one of the outputs of code block 1 there was a voltage of a logical unit, then the output of element 9 OR-NOT formed a logical zero, and therefore also at B1 of the output of element 13 of delay 13 the zero is preserved (for a time 1 since the change in the state of the code block 1. As a result, a single pulse generator 3 generates a signal of duration t; (Tty value). During time 7, both sources of Light, both the previous source 7 and about Turning source 8 are made ON sequentially At the end of time t;., switch 5 is opened, which bypasses the light source 7, so that its luminescence is stopped, and the brightness-emitting source 8 reaches the rated load.

In the eighth cycle, the start of operation of the device is similar to the seventh cycle of operation, however, at the end of a single impulse T generator at the output 3, a single voltage level is generated at the output of element 10 I (as in the second device operation cycle), as a result of which switch 14 switches to state indicated in FIG. 20, which provides illumination of both light sources.

Nine cycles of operation are similar to the seventh, however, when a single impulse with a duration T ends at output 1 of generator 3, a key 6 opens, shunting the light source 8, stops luminous as a result, and the brightness of the light 7 returns to nominal.

It should be noted that the fluctuation of the brightness of the light source 7 in the ninth cycle of the device, as well as the fluctuation of the brightness of the source of the 8-light in the eighth cycle of operation, due to the successive switching on of two light sources on. time T, when the right value of f is chosen by the human eye, is not perceived either because of the inertia of the vision, or because of the inertia of the process of cooling the filaments of the incandescent light sources.

The nine cycles of operation of the proposed device listed above include, without exception, the technically different processes of changing the glow of light sources. It is clear that in the case of real operation of the device, the change of the processes of the luminous sources of light may proceed in a different sequence, and some of these cycles may be absent.

The economic effect of using the device is due to its technical features.
