Many computers contain taShler, which, in conjunction with algorithms that implement control functions, can control a variety of objects and processes in real time.

All of the aforementioned devices containing taSh.1er do not allow remote bewireless control of electronic equipment.

A device for controlling electronic equipment is known, comprising a remote control unit that transmits a radio or ultrasound signal that controls electronic equipment and a unit installed in the same equipment that receives a signal and controls the operation of the equipment. The remote control unit contains a time counter; a detector for matching the contents of the counter with a predetermined value that generates a transmission control signal; a microphone; a transmitter that converts the microphone signal into a radio signal according to the transmission control signal. The control unit contains a radio signal receiver that converts it into a speech signal; a circuit that recognizes the received speech signal; a circuit that controls electronic equipment based on the recognition result (az.7P 63-53519 op. 24.10.88 IvQffi G04 G 15 / OOj.

The time counter with a matching circuit (timer) in this device is used only for programmatic transmission control. The electronic equipment itself is controlled based on the result of speech recognition, which requires a rather complex recognition circuit. The reliability of speech recognition is low, so the set of functions for controlling electronic equipment is limited.

Remote control systems (DU) of electronic equipment using infrared (IR) radiation are widespread. For transmitting commands from the control panel to the receiving device, a pulse encoded infrared radiation stream is used, which has a definite signal structure. yr ШЩняххкядн | HESH: in domestic remote control systems, the transmitted information is encoded by changing the time intervals by short pulses of infrared radiation. The encoded package contains the address code of the system's operating rubber, the command code, and several shshulshih shuls, necessary for synchronization and ensuring noise immunity of the system Ш ДУ.

A device is known for generating such control IR signals, which is a remote control remote control included in the system of remote control television (TV) receiver. .Zdha (USSTT Televisions. Zh-Beams Remote System, Well, Radio, 1990.

F5, p. 41). The remote control contains a keyboard, an encoder, and an F-transmitting key. The encoder, on the basis of a poll of keypad faults, forms a sequence of encoded packages, the number of which in the sequence corresponds to the duration of pressing a button on the keyboard. The transmitting key converts this sequence of command transmissions into W-signals, which are then sent to the remote control system device integrated in the TV receiver.

Thus, the remote control is designed for remote operational control. In this system, the possibility of programmed control of a TV receiver from taShera is not considered. There is no built-in timer device in most TV models that are produced and in many planned to be introduced (A. Grif and other Communication -93. Televisions and other video equipment, J. Radio, 1993, F “IO, p. 2).

with a memory of control programs, built-in to the receiver part of the IR remote control system Oulp-DU-005, designed for wireless remote control and commutation of signals from household audio-reproducing stereo equipment: a stereo tape recorder, as well as two additional audio-reproducing devices (memory) and a power amplifier (UM). As a memory device, a tuner, an electric player, a tape recorder can be used (A. Chebykin. Remote control system Olish-D7-005, J. Radio, 1990, U, p. 72). Remote operational control in the system is carried out using 16 commands transmitted from the remote control panel in the Zh-band. The system has a local control keyboard located on the front panel of the receiving part of the remote control system.

It is generally accepted in world practice that in remote control systems local etching is of an auxiliary nature, therefore / to save space and the number of buttons it usually has shortened functions. So in the system under consideration, only local power management and switching of memory signals are provided from the local control panel,

Program control from the electronic clock can be carried out according to two programs, the first program (first) is designed to turn on all the memory at a specified time during the start-up, while the tape recorder is switched on to play forward, the second program (second timer) is designed to simultaneously turn off the sources, so Thus, the program | control of electronic equipment in this system is limited to only two functions. The electronic control buttons are also located on the local control panel for hours,

A significant increase in the possible control functions in such a remote control system from electronic clocks built into the fast-and-fast system

leads to excessive z / increase in the number of buttons, as well as to complicating the scheme of the control system. Using such a system becomes difficult and often inconvenient.

The developers are faced with the task of creating simple and easy-to-use control systems for electronic equipment with enhanced control capabilities. In the future, the solution to this problem when controlling, for example, TV receivers is associated with the creation of new TV models with an interactive microprocessor control system

And by displaying information on the screen in the form of a menu of production problems and new TV models in Russia, J. Radio, 1993, isS, p. 9).

The proposed utility model allows for expanding capabilities and enhancing the convenience in controlling electronic equipment without the need for modernization of the mating control.

The inventive program control device for Ш Ш ДУ systems contains a timer with the memory of control programs and differs from the prototype in that it contains an Ж-signal transmitter, which is engraved by a timer through a control function converter into sets of command packages having the signal structure used in IR remote control systems.

Such a device will allow remote program control of one or several electronic devices that are functionally connected between: / themselves or not connected at all, provided that it is provided with a remote control, common to all or separate for each device or group of devices.

The number of different program control functions can be increased in comparison with the prototype and depends only on the capabilities

YK DU, and the maximum number of control programs is limited only by the total amount of program memory.

Considering that each control program has its own set of command messages, and the command messages in the set can be different, i.e. designed to / control various cutting or even devices, then different modes and devices can be controlled one at a time control program, the Number of possible control functions in this case increases due to combinations of simple control functions. This allows more efficient use of the available program memory. In addition, the process ss

Complications of complex control programs.

Thus, the use of a software control device for IR remote control systems as an addition to the already existing / operational and nporpaj.aaiOMy control of electronic equipment expands its capabilities and increases its usability.

Electronic equipment can be controlled both by hard constant programs laid down in the manufacture of the device, and by programs, I suppose they can be changed quickly. In the latter case, you must have a data input device that can also be used to set the operating modes of the Program Control Unit.

An input device can be implemented, for example, in the form of a keyboard block. Moreover, in specific forms of execution, the KSXSX program control device will be able to combine part or all of the functions of a traditional IR remote control, i.e. This allows the remote control of electronic equipment to be implemented as well. Since the simple program control functions correspond to the operational control commands, the same keyboard buttons can be used both when entering the control functions into the program memory and when directly sending remote control commands.

The input of control programs can also be organized from devices for reading information from magnetic and optical media, as well as via data transmission channels, in particular from computers. This will provide, if necessary, the possibility of preliminary preparation of control programs and their faster input, as well as the possibility of long-term storage

program / m control, including on external computer memory devices. In this case, the capabilities of computers can be used to prepare programs

control of electronic equipment by processing in dialogue mode the information received from devices such as a modem, network adapter, scanner, speech recognition device, set-top box, etc. In addition, on the basis of a computer, software implementation of the taSher and the converter of control functions is possible, while the IR signal transmitter is connected to the interface or computer port. Thus, the computer itself will be able to perform the functions of a device for programmed control of electronic equipment as part of IR remote control systems.

To ensure clarity and ease of use, the program control device may include a device for displaying useful information in the form of a display or indicator device. On the display screen or on the indicator, in particular, the entered control programs, the operating mode of the device, the values of the current time, etc. can be displayed. In this case, the program control device in parallel with its main purpose can be used as a household electronic clock, and in the presence of an audible alarm, as a clock with a multi-program alarm clock.

The necessary elements of a device for software control of electronic equipment for Zh DU systems is a timer with memory of control programs I, a transmitter of Zh-signals 2, and a converter of control functions 3. Such a structural circuit has a device that allows remote control of one or several electronic devices via hard control programs.

If it is necessary to implement remote control by programs that allow them to be changed, then the program control device must contain input device 4, through which the control program can be entered, and also the timer and converter operation settings can be set. In addition, the input device can commands for operational control of electronic equipment are introduced.

For ease of use and to ensure clarity, the program control device may comprise a device 5 for displaying inputted control programs and operating modes, as well as current time values,

The device may include an audible or light signaling device b, which notifies of the occurrence of a moment in time, the value of which is stored in the memory of the control program. The signaling device is controlled either by the converter of control functions 3, or by timer I.

As an example of implementation, a device is proposed for remote program control of domestic TV receivers of the 3-5th generation, for example, TVs 4 USTsG. The device also allows you to implement the software control tuner for receiving satellite television (STV), (the design is described in J. Radio, 1993, M-7), provided that it is equipped with a system of remote control (J. Radio, 1993, F "II, p. II,

A. Goltsev, Tuner for receiving GTB).

Program control is implemented using 10 control functions and allows you to:

- switching on the TV receiver (STV tuner) from the standby mode at the set time and switching it to the lyubotl from the highly tuned television channels (control functions 1-8);

-automatic sequential switching of television channels, starting from the first channel with a period of 4 seconds. within one minute (control function 9);

-work in the multi-program alarm mode (control function 0).

In addition, it provides:

- input and indication of the operating modes of the software control device;

- input and display of up to 16 control programs;

- input and indication of the current time and days of the week;

- giving a sound signal at the beginning of the formation of remote control commands;

- turning on the TV receiver1 (STV tuner) and switching the television channels in the operational control mode using the numeric buttons of the main keyboard;

p | adjusting the sound volume and turning off the TV with the help of an additional manipulator designed for disabled people, people with reduced mobility and impaired coordination of movement, paralyzed, etc.

In the proposed device, the structural diagram of which is shown in Fig. 3, as a timer I, an LSI of a multi-timer KRYUHbVIG included in a typical scheme is used. Technical Character.

The commutation unit 4 (Fig. 3) consists of a main bay of kokm / tators and an additional manipulator. The main block of push-button switches is connected to the switchboard KP 101b-VI1 in accordance with its typical switching circuit. It should be noted that KIO-K1o push-buttons in the programmable control device are not used and be excluded from the schema. An additional manipulator is connected to the converter of functions of the salary 3, the operation of which is described below.

As an indicator 5 (FIG. 3), a SHSh 3-5A vacuum multi-digit indicator was used, the parameters and purpose of which conclusions are given in the reference: B.L. Lisitsyn, Domestic indicating devices and their foreign counterparts, Moscow, f, Radio and communications, 1993, p. 112. The indicator is connected to the taShler according to their reference data.

As a sound signaling device b (Fig. 3), a piezoceramic radiator ZP1-12 is used.

Reference data and recommendations on the use of KP I506xXJII microcircuits are given in the article: V. Plotnikov, Integrated Circuits for Remote Control Systems, g. Radio, 1986.6, p. 48.

The power supply to the converter of the control functions (Fig. 4) is negative with respect to the OA common bus voltage D /. This should be taken into account when connecting the power supply circuitry I -o 10.

Buses Do, Ш2, FK, СБ are connected to the input of the scegla from the corresponding outputs of the microcircuit. TYPE КР, С see the above typical cxeivc / its switching on).

The PER bus from the output of the microchip SC (Fig. 4) is connected to the input of the IR transmitting key.

The ZS bus from the collector of the transistor UT I is connected to the ZP1-12 sound annunciator (it is shown in the typical timer switching circuit), which should be DISCONNECTED from the output of the SB thaler.

An additional push-button manipulator K1, K2, KZ is shown in the diagram of the converter of control functions (Fig. 4). It is connected to the control inputs of Koi ftiyTaTopaD9.

Consider the work: converter control functions presented in figure 4.

A serial binary code of the current control function, accompanied by the strobe D5, is periodically fed to the input of the shift register 2 via the RK bus. The strobe is limited in magnitude to the chain i / 2 I, / I and in / i / L 9 —Currented by element I. I microspot I.

The signal load of the RC is the resistance / .2.

The serial code of the control function advances along the shift register L2 as each of the four clock pulses arrives, highlighted by the element L1.2 from the sequence of clock pulses Ф2.

The parallel previous code of the control function obtained at the outputs of the shift register 2 is overwritten in register 3 with the arrival of the high front of gate D5. Further, from the outputs of the parallel register, the three lowest code bits go to the inputs of the channel multiplexer b.

When coinciding to within a minute of the current time counted by TaMiviepOM, with one of the time values stored in the control program memory, a sequence of bursts of sound frequency pulses appearing on the SB bus appears for a period of one second throughout the entire coincidence time, t .e. within one hour. The duration of each burst of pulses is 0.5 seconds, s.

With each first BMD of the bursts, a waiting multivibrator is assembled, assembled on the elements L3 and L4, which generates pulses of duration C1, depending on the time condition of Bsliuina (see voltage diagram UI, Fig. 5).

As a result of the passage of the sequence of these pulses through the circuit / 14, Л 5,, C2 at the output of the shaper /) 4.1, a negative voltage drop with a delayed front appears (see diagram 2, Fig. 5). The delay value depends on the time constant of the circuit C2, / 4, A pulse with a duration equal to the delay from the output of the coincidence element L4.2 (see diagram y1ГЗ, Fig. 5) switches the / - trigger assembled on the elements L4.3 and L4.4. The trigger switches to the initial state with the arrival of the trailing edge of the first pulse of the sequence (see diagram 7U4, Fig. 5).

- BV - / /

Thus, at the output of element b4.4, a single I1 pulse is formed, which in time coincides with the first impulse of sequence VI, which is valid for one year. this inverter after inverting element 5.3 goes to the input of the resolution of the multiplexer-switch o8. At the same time, through the multiplexer comments on the creeping inputs of the cipher b10, determine the three least significant bits of the control function code. The encoder 10 generates a corresponding set of command premises, the number of which in the set is determined by the duration of the impulse pulse V.4,

At this time, the element b 5.1 of the SB signal is allocated the first burst of pulses, which is fed to the sound signaling device through the transistor switch UT through the bus ZS (see figure 4).

The generated set of command messages is sent via the PER bus to the IR transmitting key, from which the Zh-signals are transmitted further to the IR receiver and command decoder, the TV remote control system (STV tuner) to turn on the television channel I to 8 in accordance with the control function code. control functions 9 (binary: IOOI code) the set will contain command messages intended for switching on the first television / channel.

The pulses generated by 1 kDA are scanned with a vibrator every second / second, starting from the second, they are counted by a counter consisting of two 7) triggers: in 6.1 and 73 b.2 (diagrams of voltages V.5 and 1/6 at their inverted outputs are shown in Figs. 5).

If at the outputs of the parallel register) 3 there is a function control code 9 (binary code -IOOI), the output of the L5.4 element will have a low voltage level (see Fig. 4). Then, at the output of element 157.2, a sequence of pulses 1/7 appears (see Fig. 5). This sequence is fed to the control input of the first circuit of the microsystem's mutator (the upper one according to the scheme). In this case, every 4 seconds, the encoder L10, controlled by this com / tator, will form command messages intended to switch to the tracking television channel with increasing its number . Thus, as a result of the implementation of the control function 9, a combined set of command premises is formed over a minute to control two different modes of switching television channels. For control functions I through 8, the sequence V7 at the output of the element) b7,2 is not formed, i.e. the formation of the command package occurs only during the action of a single pulse 1/4, coinciding in time with the arrival of the first packet of pulses along the SB bus. After the action of these packs of schulse, after a time, depending on the constant. time of the discharge circuit C2, A.4, Y5, at the output of the element 4.1 appears a positive voltage drop U2 (figure 5). After this, it becomes possible to form a new set of command premises corresponding to the next control program, but not earlier than in a minute. If the code of the current control function is O (binary code is 0000), then the output of element L7.1 has a high voltage level, and the output of element L5.2 is correspondingly low (Fig. 4). It prohibits the passage of pulses from the output / 2.- trigger via element 5.3 to the input of permission of co-router 8. Therefore, when the function of forming a set of command messages is not implemented. In addition, the output of element I) 4.1 has a high level, and then from the output / 2. a trigger to the input of element 5.1, a sequence of pulses arriving, permitting the passage of packets of shulse of sound frequency to the signaling device, is received for the entire min / s, while the SB signal is active. H

w 4 - w Thus, the program control is implemented using ten control functions: -functions I to 8 - to turn on the TV receiver or STV tuner and switch to: TV channel with the corresponding number; -function 9 - for sequential viewing of television channels, starting from the first; -O function provides the device in alarm mode. The programmable control device for the Zh DU systems allows for the operational control of TV receivers (STV tuner) using the numeric buttons of the main keyboard connected to the timer. This is possible in the current time display mode with the bnvi audible alarm activated. When the button is pressed, a sequence of sound frequency pulses is generated via the SB bus (Fig. 4), which starts the control function converter circuit, the output of which is a sequence of command messages corresponding to the pressed button via the PER bus . In addition, the device may contain an additional push-button manipulator K1, K2, KZ (Fig. 4), used when watching TV shows on preset programs by people with disabilities, people with reduced mobility and impaired coordination of movement. The KI button is designed to turn off the TV buttons K2 and KZ - to adjust the sound volume in the building up and down. The number of possible operational control commands can be significantly increased by connecting an additional keyboard to the inputs A - H and a - / 1 of the encoder Jt) TO (Fig. 4) in accordance with the typical circuit of the KR microcircuit, (see article: V. Plotnikov VlHTerral microcircuits for remote control systems, J. Radio, 1986.1 "b, p. 48). tfe can be organized under the control of a computer, if in the main keyboard connected to the timer KR, 101b, VI1, instead of push-button switches, use electronic scammers, for example:,,. In this case, their control inputs are connected to the output port of the computer.

An additional indicator may be connected to the converter of control functions 3 (FIG. 3) to display the control function. This is advisable if, as the main indicator connected to the VI1 timer, an indicator is used that does not have an additional discharge to display it, for example, type ШЛ 4-7 / 5. In this case, an additional seven-segment indicator is connected to the outputs of the parallel register (Fig. 4) through a decoder, for example, of the type K564ID5 (see reference: V.L.Shilo Popular digital circuits, Moscow, Radio and communications, 1987, p. 265).

The features of the KRUTB VI timer in the nporpaiviMHoro control device are not fully used. In particular, the number of possible program control functions can be increased to 16. Н8 this will lead to some complication of the control function converter circuit (Fig. 4). In this case, it is advisable to use a single-chip microcomputer, for example, from the KI8I4, KI8I6 series, KI820 or similar (I.V. Varlamov, I.L. Kasatkin, Microprocessors in household appliances, Moscow, Radio and communications, 1989). In this case, the operation algorithm of the converter of control functions, similar to that described above, is implemented in the form of programs stored in the ROM.

On the basis of micro-computers, it is also possible to implement the entire program control device (Fig. 1 and Fig. 2). In this case, the internal tayeer of the micro-computer itself is used as tasher I, and the transmitter of the LC signal 2 is connected to the output port COMPUTER,

- 57 The described version of the device (Fig. 3) can be useful in everyday life, and can also be used at exhibitions and in stores for simultaneous l / control of several TV sets at once when demonstrating their work on open channels.
