The present invention relates to a self-winding automatic control device for controlling a sunshade or similar device which is protected from the sun in either of the two operating directions of the automatic control device.

The device includes an electromagnetic cross-section, and one input of this circuit is connected to a pick-up prepared for measuring the intensity of meteorological phenomena, such as wind speed, temperature, solar light, and so on. The input is connected to a device for adjusting the predetermined limit of strength as described above and the output of this circuit is connected to the control means.

Such control means are prepared to illuminate the luminous indicator as soon as the intensity of the meteorological phenomenon equals or exceeds the predetermined threshold to control the onset of the passage of the first predetermined delay period and then shades in the first direction at the end of the first delay period. Is prepared to control the operation of the.

If the first delay period has ended, as soon as the strength falls below the predetermined threshold, these controls are also prepared to adjust the onset of the passage of the second scheduled delay period, then the shade of the shade in the second direction at the end of the second delay period. It is prepared to control the operation.

The function of the first and second delay periods, for example with a duration of 0.1 minutes, is that of the awning's direction of operation if the intensity of the phenomena rapidly passes completely below a predetermined threshold and then to a value greater than then. It is to prevent continual change and excessive closure.

In this type of automatic control device known, the luminous indicator directly connected to the output of the electromagnetic comparator had an operation directly and alone connected to an existing level of meteorological intensity with respect to a predetermined adjusted limit of meteorological intensity.

As long as the intensity is equal to or greater than this limit, the light indicator is illuminated and as soon as the intensity drops below the limit, the light indicator is turned off.

This is preceded by the control of the shade operation towards the second direction of the controller throughout the complete period of the second delay period and whether the second delay period is in progress and the command to control the shade in the second direction is simply given or the automatic control fails. Do not let the observer know if you are born.

Until now, the only way to know this is to wait for the end of the cycle at approximately the same position as the second delay period, and then make sure that the sunshade works effectively in the second direction of the control.

For example, problems arise when the sensed intensity is the intensity of sunlight.

If at any given moment the observer confirms that there is no light by occupying the open state of the control, the observer assumes that the facility has failed.

In the automatic control device according to the present invention, when the first delay period has already reached the end of the period, the light emitting indicator flashes at the above-mentioned frequency until at least the end of the second predetermined delay period as soon as the intensity of the meteorological phenomenon becomes less than the predetermined limit value. It features a driver control of the oscillation system operating at a constant frequency to make it work.

For example, the present invention may be used when the control device is composed of a micro-calculator that accommodates a series of programs in non-valatile memory (ROM).

The automatic control device includes a special program that precedes the program to test the presence of one intensity where the continuation of the program is less than the predetermined threshold and to test whether the end of the first predetermined delay period has elapsed and whether the second predetermined delay period has ended. It is characterized by including the continuation program itself preceding the program prepared for testing.

The automatic control unit is composed of a subprogram for alternating binary values of the decaying memory (RAM) location of the micro-calator at a constant frequency, where the negative response is given to the test of the last program and the positive response is the two preceding programs. It is characterized in that it comprises means for controlling the flashing of a light emitting indicator to be controlled by the last indication of a program prepared solely to test whether the second predetermined delay period has been completed, if given in the test of.

This subprogram for alternating binary values is preceded by a subprogram for the shift of this binary value towards the light emission indicator to produce the last flash at the above-mentioned frequency.

For example, the present invention provides that the control means are constituted by first and second logic delay circuits, and the second circuit is as soon as the intensity is less than the predetermined delay period if the first predetermined delay period initiated by the first circuit reaches its end in advance. It may be used when it is prepared to control the onset of the passage of the second predetermined delay period.

In this case, the automatic control device is connected with the first input to the output of the electromagnetic comparator, the second input to the output of the second logic delay circuit, the third input to the oscillator to prepare the flash generation frequency, and the output to emit light. And means for controlling the flashing of the light emitting indicator constituted by a logic control circuit connected to the indicator.

This logic control circuit produces an electronic flash comparator only when the logic state of the output matches the intensity once smaller than the predetermined limit and at the same time the second logic delay circuit coincides with the beginning of the elapse of the second delay period. It is supposed to.

The present invention provides an improved automatic control apparatus which can indicate to the observer that the above-described control apparatus is operating normally without the need for the use of an imposing indicator or display system during the second delay period following the control of the second operating direction of the shade. The purpose is to facilitate production.

The accompanying drawings show a specific implementation of a control device according to the invention.

As shown in FIG. 1, the automatic control device comprises a pickup 1 prepared for measuring the intensity (for example) of the sun's light at each moment.

The output of the pickup 1 is connected to the input E ₁ of the electronic traveling circuit 2 whose output S _{1 is} connected to the non-inverting input E + of the electromagnetic comparator 3.

The circuit 2 is meant to make the electrical information given by the pick-up 1 compatible with the comparative range of the electronic comparator 3.

The device 4 for adjusting the predetermined limit of the intensity of sunlight, such as a potentiometer, had the output of the device connected to the reverse input (E−) of the same residual cross-section 3.

The output S ₂ of the comparator circuit 3 is a microcalorator 5 (e.g., which constitutes a control means meaning controlling the winding or unfolding of the shade for protection (for example) from the sun. It is connected to the input K ₅ of the Texas Instruments TMS 1000).

At this end, the output terminals R ₁ and R ₂ of the micro-calculator 5 are connected to a motor (not shown in the drawing) which drives the sunshade through the medium of the output connecting device 6, 7. Is connected.

The terminal R ₁ of the microcalorator 5 controls the first direction of rotation of the motor corresponding to (e.g.) the unfolding of the shade and the terminal R ₂ controls the second direction corresponding to the winding of the shade. .

In addition, the micro-calator 5 includes an output terminal O connected to the light emitting indicator 9 through the medium of the connecting device 8.

The output connection devices 6 and 7 are connected to an amplifier (for example) which respectively controls each relay for controlling the rotation of the motor in one of two directions.

The connection device 8 is also connected to one amplifier (for example).

The microcalorator 5 includes a non-destructive memory (ROM) specially containing a program 20 for testing the presence of the intensity of sunlight smaller than the predetermined limit as shown in FIG.

The last command of the program 20 is the address of the address of the first command of the program 24 prepared for testing whether the first delay period T ₁ has ended or of the program 21 for controlling the permanent illumination of the light emitting indicator. Conditional call command for address of first command.

The last command of the program 21 precedes the first command of the program 22 for the delay T ₁ .

This program 22 is intended for the reduction calculator of the delay portion T ₁ provided in the preposition side micro-calurator 5.

The last command of the program 22 precedes the first command of the prepared program 23 to test whether the first delay period T ₁ has ended and the last command indicates the first operating direction of the shade, i.e., the unfolding direction of the device. A program which is a conditional calling instruction directed to the address portion of the first instruction of the program 25 for control, or to the address portion of the first instruction of the program 35 prepared to test whether the second delay device T ₂ is in advance. Precedes it.

The last instruction of the program 35 is a conditional call instruction directed to the address of the first instruction of the program 31 or to the address of the first instruction of the program 25 to control the second operating direction of the shade, i.e. the winding direction of the device. to be.

The last command of the program 31 precedes the first command of the program 20.

The last command of the program 25 precedes the first command of the program 20.

The last instruction of the program 24 prepared to test whether the first delay period T ₁ has ended is directed to or addressed to the address of the first instruction of the program 24b that tests whether the second delay period T ₂ is already in progress. Is a conditional call instruction directed to the address of the first instruction of the program 27 for (T ₂ ).

This program 27 is intended for the reduction measurer for the delay T ₂ prepared in the micro-calator 5 at all positions.

The last instruction of the program 24b is a conditional call instruction capable of being the address portion of the first instruction of the program 27 or the address portion of the first instruction of the program 33 for controlling the extinction of the light emitting instruction circuit 9.

The last command of the program 33 precedes the first command of the program 31 for controlling the second direction of operation of the shade.

The last instruction of the program 27 precedes the first instruction of the program 28 prepared to test whether the second delay period T ₂ has ended, and the last instruction is a program 33 for controlling the extinction of the indicator 9. Precedes the program, which is a conditional call instruction to the address portion of the first instruction of) or to the address portion of the first instruction of the program 29 for controlling the first direction of operation of the shade.

The last instruction of this program 29 precedes the first instruction of the sub-program to alter the binary value of the position of the microcalator's volatile memory alternately at a constant frequency.

The last command of this subprogram 30 precedes the first command of the subprogram 32 for moving this binary value to the light emitting indicator 9.

The combination of subprograms 30 and 32 constitutes an oscillator circuit operating at a given frequency that alternately changes the binary values defined above.

The last instruction of this subprogram 32 precedes the first instruction of the program 20.

For example, consider that the second direction, the direction in which the last operating direction of the device is less than the predetermined limit for a certain period greater than the second predetermined delay period T ₂ , is fixed at the initial position.

Even if a voltage is supplied to the automatic control device, the light emitting indicator 9 is turned off if the intensity of sunlight is less than a predetermined limit for a period larger than the second delay period T ₂ .

As soon as the pick-up 1 measures the intensity of sunlight larger than the threshold of the predetermined intensity by the adjusting device 4, the output S ₂ of the electron-comparator 3 proceeds from the logic state D to the state 1, and the program 20 ) Judges the presence of this state and programs 21 (22) and (23) are achieved sequentially and the indicator (9) continues to grow, e.g. a delay period (T ₁ ) of holding for one minute is started and then The countdown begins.

As soon as the program 23 determines that the first delay period T ₁ has not ended, the program 35 is executed to test whether the second delay period is already in progress.

As mentioned above, the shade is considered taking into account the initial position of the shade so that the program tests that the second delay period T ₂ is not already in progress and determines the second operating direction of the shade, called the direction in which the program 31 winds up. The control continues and the sunshade remains wound.

As soon as the program 23 tests the end of the first delay period T ₁ , the program 25 is executed to control the first operating direction of the sunshade, which is the winding direction.

If the intensity of sunlight is once less than the predetermined limit before the first delay period T ₁ has fully elapsed, the program 20 tests this phenomenon.

And implement programs 24 and 24b to test that the first delay period T ₁ has not ended and that the second delay period T ₂ is not already in progress.

The programs 33 and 31 are then executed and the indicator 9 goes out and the second direction of operation continues to be controlled.

The sunshade remains wound.

After the sunshade is controlled and released in its first direction of operation, the program 20 tests this phenomenon when the intensity of the solar light is once lower than the predetermined limit and then the program 24 indicates that the first delay period T ₁ is over. Tests and programs 27 and 28 are in turn executed, and a second delay period T ₂ is started which is held for 10 minutes (for example).

Then the countdown begins.

While the program 28 tests that the second delay period T ₂ is not over, the programs 29, 30 and 32 are executed in turn, and the shade is controlled to operate in the first direction of the device, called loosening. .

Thus, the binary value at the position recorded in the RAM memory of the micro-calator 5 is alternately changed at a constant frequency and the binary value is moved to the light emitting indicator 9.

Therefore, the light emitting indicator 9 starts to flash.

This indicator 9 flashes to indicate that the control is operating normally from the start of the second delay period T ₂ and that the shade is to be controlled soon in the second direction of the device.

As soon as the program 28 tests that the second delay period T ₂ is over, the programs 33 and 31 are sequentially executed and the light emitting indicator 9 is turned off.

The sunshade is then controlled to act in the second direction of the device, called the winding.

Sunshade is wound.

If the intensity of sunlight is once greater than or equal to the predetermined threshold before the second delay period T ₂ has fully elapsed, the program 20 tests this phenomenon.

Then, the programs 21, 22, 23 are sequentially executed, the light emitting indicator 9 is lighted up, and the first delay period T ₁ is started once more and then the counterdown starts.

The program 35 tests that the second delay period T ₂ is already in progress while the program 23 tests that the first delay period T ₁ has not ended.

The program 25 then continues to control the operation of the sunshade in the first direction of the device, called loosening.

The sunshade remains loose.

As soon as the program 23 tests that the first delay period T ₁ has ended, the program 25 is implemented and the operation of the sunshade continues to be controlled in the first direction called loosening.

The sunshade remains loose.

Linking between the programs 20, 21, 22, 23, 25 makes it possible to restart the second delay period T ₂ when the intensity of sunlight is substantially less than the predetermined limit. .

If the first delay period T ₁ is hindered before reaching its end by the fact that the luminous intensity is again smaller than the predetermined threshold, the program 20 tests this situation and the program 24 determines the first delay. Test that period T ₁ is not over and program 24b tests that a second delay period is already in progress.

The programs 27, 28, 29, 30 and 32 are sequentially executed as already mentioned.

The first operating direction of the sunshade is continuously controlled and the indicator 9 changes from the permanent luminous position to the flash position.

This state continues until the program 28 determines that the second delay period T ₂ is over.

In the second specific embodiment shown in FIG. 3, there is no microcalator 5.

The micro-calculator 5 is controlled by two logic delay circuits CLT ₁ and CLT ₂ and a non-inverting gate 10 and an inverted gate to control the first and second operating directions of the sunshade. inverting gate 11, by means of means constituted by a logic delay circuit 13 for controlling the flashing of the electron oscillator 12 and the light emitting indicator 9;

The logic delay circuit (CLT ₁ ) includes an input terminal (R ₃ ) and a start input terminal (T ₃ ) for returning to zero, both of which are connected to the output terminal (S ₂ ) of the electromagnetic comparator (3). The output terminal S ₃ is connected to the start input terminal T ₄ of the logic delay circuit CLT ₂ .

The output terminal S ₄ of this circuit CLT ₂ is connected to the output connecting device 6 via the medium of the non-reverse gate 10 and to the output connecting device 7 through the medium of the reverse gate 11. The other is connected.

By way of example, a terminal R for returning to zero is connected to a terminal R ₃ , and a start input terminal T is connected to an output of the reverse gate 15 whose input is connected to the terminal T ₃ . The logic circuit CLT ₁ is constituted by a stable electronic circuit 14 (eg NE555 of SIGNETICS).

Two output terminals (S) of the stabilizing electronic circuit 14 has been connected to the inverse input of the "AND" gate 16 is connected to the second input bugger the terminal (T _3).

The output of this “AND” gate is connected to an output terminal (S ₃ ).

The terminal RC of the monostable circuit 14 is connected to a register / capacitor system R ₁ -C ₁ which determines the passage of the first delay period T ₁ by determining the period of this monostable circuit as is known. do.

By way of example, logic circuit CLT ₂ is a monostable electronic circuit 18 having a start input terminal T connected to the base of a PNP transistor 19 with the output of the reverse gate 17 and a collector connected to ground. Example: NE555 of SIGNETICS

The input of this gator 17 is connected to an input terminal T ₄ .

The output terminal S of the circuit 18 is connected to the output terminal S ₄ .

The terminal RC of the monostable electronic circuit 18 is connected to the resistor / capacitor system R ₂ -C ₂ and to the transistor 19.

Therefore, the system R ₂ -C ₂ determines the period of this monostable circuit and the elapse of the second delay period T ₂ .

For example, the logic control circuit 13 is constituted by the AND gate 20 and the OR gate 21.

The AND gate 20 is connected to the first input terminal E ₂ connected to the terminal S ₄ , the second input terminal E ₃ connected to the output S ₆ of the oscillation circuit 12, and an output to the electronic comparator ( The output of the gate 20 is connected to the first input terminal of the OR gate 21, the second of which is connected to the output terminal E ₄ connected to S ₂ ).

The output S ₅ of this OR gate is connected to the light emitting indicator 9 through the medium of the connecting device 8.

For example, the electronic oscillator circuit 12, as is known, determines the period of the unstable multivibrator and consequently the terminal RC in the register / capacitor system R ₃ -C ₃ that determines the flash frequency of the indicator 9. ₃ ) is composed of an unstable multivibrator connected.

All other components are identical to those of the first specific embodiment already described (see FIG. 1).

Assume that the initial position of the shade is the same as the position selected to describe the operation of the first specific embodiment (see FIGS. 1 and 2).

As soon as the intensity of sunlight exceeds the predetermined limit, the output S ₂ of the electron-comparator 3 proceeds to the logic state 1.

This causes the output S ₅ of the logic control circuit 13 having the effect of illuminating the light emitting indicator 9 through the medium of the connecting device 8 to the state 1.

At the same time, as soon as the output S ₂ of the electron-comparator 3 proceeds to the logic state 1, the terminals R and T of the monostable circuit 14 go to 1 and 0, respectively, and this is the same circuit 14 Has the effect of causing the output S of to proceed to 1 and to start the start of the first delay period T ₁ .

Therefore, the outputs S ₃ and S _{4 of} each of the logic delay circuits CLT ₁ and CLT ₂ remain at zero as long as the delay period T ₁ determined by the system R _1- C ₁ lasts. have.

As soon as this period T ₁ ends, the output S of the monostable circuit 14 goes to state 0, which is responsible for the effect of causing the output S ₃ to go to state 1 and the medium of the non-reverse gate 10. It has the effect of controlling the first direction of operation of the sunshade.

Indeed, while terminal S ₃ goes to state 1, like terminal 24, input T of monostable circuit 18 passes to state 0 and its output S passes to state 1. .

The reason why the output of the reverse gate 17 is in state 0 is that the output controls the transistor 19 in the pass state, which shorts the battery C ₂ and prevents the output from changing, thus causing a second delay period T. ₂ ) can not be elapsed and the sunshade is released.

If the intensity of sunlight falls below a predetermined threshold, the output S ₂ of the electron-comparator 3 passes through to logic state 0 before the end of the first delay period T ₁ .

Since the output S ₄ of the logic delay circuit CLT ₂ is equal to 0, the output S ₅ passes through 0, which has the effect of extinguishing the light emitting indicator 9.

At the same time, as soon as output S ₂ goes to state 0, terminals R and T of monostable circuit 14 go to states 0 and 1, respectively, which indicates that output S of circuit 14 is from state 1 The output S ₃ stops at zero and the shade is uncontrolled and wound because it causes the passage to zero and stops, and then discharges the charge of the battery C ₁ to interrupt the first delay period T ₁ . Remain.

After the end of the first delay period T ₁ , when the intensity of sunlight becomes less than the predetermined limit value, the output S ₃ of the logic delay circuit CLT ₁ changes to state 0 and the monostable circuit 18 Input T is in state 1.

This has the effect of causing the transistor 19 to pass through in a blocked state, thereby allowing the charging of the battery C ₂ .

The second delay period T ₂ elapses for a period determined by the system R ₂ -C ₂ .

At the same time, the output S of the monostable circuit 18 remains in state 1 and the same is true of the input E ₂ and the output E ₅ of the control circuit 13.

Since the output S ₂ is at state 0, the input terminal E ₄ of the control circuit 13 is at state 0, so the state of its output S ₅ is at the output S ₆ of the oscillation circuit 12. It only depends on the state of the connected input terminal (E ₃ ).

The indicator 9 therefore turns on and off continuously depending on the state of the output S ₆ and the indicator 9 flashes at a frequency determined by the system R ₃ -C ₃ .

As soon as the second delay period T ₂ ends, the output of the monostable circuit 18 goes to state zero.

The same also applies to the output (S ₄ ), which on the one hand controls the second direction of operation of the sunshade via the medium of the reverse gate 11, and on the other hand the input E ₂ of the control circuit 13 goes to state 0. Has the effect of causing.

Sunshade is wound.

At the same time, input terminal E ₄ is in state 0 because output S ₂ is at zero.

Therefore, whatever the state of the output S ₆ of the oscillation circuit 12, the output S ₅ of the control circuit 13 goes to the state 0, so the indicator 9 is turned off.

If the intensity of the meteorological phenomenon is greater than or equal to the predetermined limit before the end of the second delay period T ₂ , terminals S ₂ and T _{3 go} to state 1 and a new delay period T ₁ is started. .

The terminal S of the monostable circuit 14 goes to state 1 and the output S ₃ remains in state 0 as long as the new delay period T ₁ continues.

Input (T ₄ ) remains in state 0 and output (S ₄ ) remains in state 1.

At the same time, the input E ₄ is in state 1, so the output S ₅ controls the permanent illumination of the basin 9 which replaces the flash.

If the intensity of the meteorological phenomenon remains greater than or equal to the predetermined threshold for a period greater than the first delay period T ₁ , the output S of the monostable circuit 14 moves to state 0 and the output S ₃ is in the state. Go to 1.

As a result, the input T of the monostable circuit 18 is shifted to state 0 and the transistor 19 is controlled in the pass state, which has the effect of shorting the battery C ₂ and discharging its charge.

Therefore, it has an effect of falling after the passage of the second complete delay period T ₂ .

At this moment the sunshade continues to be controlled in the first release direction of the castle and the indicator 9 remains on.

This phenomenon continues as long as its intensity remains above its intended limit.

As a result, a new cycle (T ₂ ) begins to elapse as soon as this intensity is below the limit.

Without departing from the scope of the present invention, in the two specific embodiments described, the termination of a new delay period T ₁ when the second delay period T ₂ is disturbed following the strength of the solar tube exceeding a predetermined limit. It is possible to resume a new second delay period (T ₂ ) as soon as the strength falls below the predetermined limit without waiting for.
