Lamps 621,622,6z1 serve for light signaling and are incandescent lamps.

The remote control facility operates as follows.

In the initial state, all the buttons of the keyboard of the command generator 1, the microswitch 9 and the electronic switch 12 are in the open state. Transmitter 3 and receiver 4 are turned on. There is no signal at the output of transmitter 3, receiver 4 is in standby mode, at its output, as well as at the output of BC actuators, 621.6 s1 is absent. Sound off, light off.

The choice of alarm modes is provided by the operator by pressing the buttons of the keyboard of the former 1 command.

When the keyboard button of the command generator 1 is pressed, a logical O signal appears on the corresponding input of the programmable controller 11 for generating commands. The programmable controller 11 of the command generator determines which command is given and generates a code message corresponding to this command, which is sent to modulator 2. Modulator 2 modulates the frequency of the transmitter carrier signal 3 formed control signals. Transmitter 3 transmits a frequency-modulated signal via communication line 7 to receiver 4. Receiver 4 receives this signal, supplies it to demodulator 5, which demodulates the received signal and provides a demodulated control signal to programmable control controller 14 and power amplifier 13.

Since the SOUND button is pressed, the signal from the programmable control controller 14 is fed to the input of the electronic switch 12, which, under the action of this signal, connects the input of the power amplifier 13 to the output of the programmable control controller 14. The output of the programmable controller 14 controls through the electronic switch 12 to the input of the amplifier 13 power receives the signal of the selected siren. From the output of the power amplifier 13, the signal enters the horn loudspeaker bts, which generates an audio signal (siren).

The program controller 14 controls generates signals of three sirens:

1) WAIL type - intermittent tonal signal with a change in tonal frequency (0.9 ... 1.5) ± 0.2 kHz for 4 ± 0.2 s;

2) type YELP - intermittent tonal signal with a change in tonal frequency (0.7 ... 1.2) ± 0.1 kHz for 400 ± 30 ms;

3) type HI - LOW - alternating signals of the first tone - 750 Hz and the second tone - 550 Hz with the same sound duration of 500 ±. 100 ms

The type of siren is selected by pressing the SOUND button, namely:

1) the first press of a button turns on a quick siren (like YELP)

2) the second press of the button turns on the slow siren (WAIL type)

3) the third press includes a two-tone siren (type Ш - LOW).

When you press the button QUIET keyboard shaper 1 commands programmable controller 14 etching generates a signal that, entering the electronic switch 12, reduces the level of the sound signal.

After pressing this button again, the sound level returns to the original one.

When the STOP button of the keyboard of the command generator 1 is pressed, the programmable controller 11 generates a corresponding code message, upon receipt of which the controller 14 turns off all previously enabled modes and returns to its original state.

When the LIGHT button of the keyboard of the command generator 1 is pressed, the operation of the programmable controller 11 for generating commands and the controller 14 controls occurs similarly to that described above, i.e. programmable controller 14 controls includes the selected mode.

when the LIGHT button is pressed for the first time, the programmable controller 14 turns on the SPLASH mode, and the voltage of + 12 V is supplied to the lamps 621, 622 from the output of the controller 14.

There is a supply of light signals from these lamps with a glimpse of the frequency (2.5 ± 0.5) Hz. In this mode, 55 W lamps work.

When the LIGHT button is pressed a second time, the programmable control controller 14 switches on the PRESENCE mode, while the signal from the output of the programmable control controller 14 is supplied to the lamp. A blinking light signal is emitted from this lamp with a frequency of (0.5 ± 0.1) Hz. In this mode, 20 W lamps work.

When the LIGHT button is pressed a third time, the programmable control controller 14 again switches on the PROBLE mode. The cycle of work is repeated.

When you press the HOT KIOPK button, the programmable control controller 14 turns on for 6 ... 10 sec the lamps 621, 6 22 in the PROBLE mode and the horn loudspeaker bts in the fast siren (YELP) playback mode. When the HOT BUTTON is pressed, the programmable control controller 14 disables previously enabled modes. After the end of the HOT FOLDER mode, the programmable control controller 14 turns on the interrupted mode.

When you press the button of the microswitch 9, the programmable controller 11 of the formation of commands generates the corresponding code package, which enters through the control channel to the programmable controller 14 of the control. The programmable control controller 14, having processed the received code packet, includes the selected mode, i.e. provides a control signal to an electronic switch 12, which connects the input of the power amplifier 13 to the demodulator 5.

Since the button of the microswitch 9 is pressed, the speech signal from the microphone 8 passes to the microphone amplifier 10, then to the input of the modulator 2 and then through the transmission channel of the control signal to the input of the demodulator 5, the output of which is the speech signal through the electronic switch 12 and the power amplifier 13 on the horn loudspeaker bts. After the transmission of voice information, the operator releases the microswitch button 9. When the microswitch 9 button is released, the signal from the microphone 8 does not pass, the microphone amplifier 10 is turned off. After turning off the microphone amplifier 10, the programmable controller 11 of the formation of commands sends the signal that the button of the microswitch 9 is released through the transmission channel of the control signal to the programmable controller 14 of the control. Programmable controller 14 controls using an electronic switch 12 turns off the amplifier 13 and the horn loudspeaker bts.

When you press the button of the microswitch 9, the programmable controller 14 controls disconnects previously enabled by the button SOUND modes. After releasing this button, the programmable control controller 14 activates the interrupted mode.

With the simultaneous pressing of two shh more buttons of the keyboard of the shaper 1 commands programmable controller 14 controls includes the mode whose priority is higher.

The priorities are as follows:

1) MICROFOP;

2) HOT BUTTON;

3)

4)

5).

Compared with the prototype of the claimed device is more convenient to use, because allows you to remotely control the required number of actuators: sound and light alarms, a headlamp, a locator for measuring vehicle speed, a car radio station, etc., without complicating the circuit design of the device as a whole, but only by changing the memory size of programmable controllers for command formation and control .
