Description

The invention relates to the field of radio, and more specifically to devices for generating harmonic and pulsed signals of a wide range of frequencies and can be used in experimental medicine for conducting experiments on antiparasitic, antibacterial and antiviral therapy of various biological objects: plants, animals and people.

A device for generating groups of frequency-modulated pulses is known, which contains generators, frequency modulators, switches, a mixer, a control panel and electrodes (see patent for invention No. 2020981, Cl. Ά61 1/36 dated 04.24.1990).

However, the known device has limited functionality, as it is designed to work in a relatively narrow frequency range from 20 Hz to 20 kHz. In addition, in the known device there is no indicator modes, which complicates the operation of the device and does not allow you to visually monitor the selected mode of operation.

The technical entity closest to the proposed technical solution is a device for generating a group of frequency spectrum pulses, containing a control switch for output frequencies, a voltage regulator, a mode indicator, a controller, a frequency synthesizer, and an amplifier with first and second outputs connected to the first power supply bus. contact electrodes, the output frequency control switch contains a button and is connected by a first output to the input of a voltage stabilizer, and the second output to the first input of the controller, the first control output of which is connected to the control input of the frequency synthesizer, the control output of which is connected to the control input of the amplifier, while the output of the voltage regulator is connected to the second power supply indicator mode buses, controller, frequency synthesizer and amplifier, and the second control output the controller is connected to the input of the mode indicator (see patent for PM No. 66205 dated February 16, 2007).

Despite certain advantages, the known device has the following technical disadvantages. First, the known device is characterized by strictly fixed modes of operation and does not allow to go beyond their boundaries. So it contains only 5 fixed frequency ranges and a fixed exposure time of 7 minutes. However, in studies not only in experimental medicine, it is sometimes necessary to go beyond the rigid boundaries of established frequency ranges, as well as the time of exposure intervals. In addition, in the known device there is no possibility of visual control, as well as programming to ensure operation in a wide range of frequencies at different voltage levels and harmonic and / or pulse waveforms.

The technical result is the expansion of functionality by providing work in a wide range of frequencies at different voltage levels and time intervals of exposure to harmonic and / or pulse signals.

An additional technical result is the provision of visual control of programming and control over the work process.

This is achieved by the fact that the Ν-frequency generator of harmonic and pulse signals contains a stabilized power source, to the outputs of which are connected a central processor equipped with a keyboard, an indicator, a frequency synthesizer, an amplifier of harmonic signals, an amplifier of pulse signals, a controlled switch and an output unit for converting voltage levels, the first and second information outputs of the central processor are connected, respectively, to the indicator and the input of the frequency synthesizer, the first and second outputs to connected to the information inputs of the amplifiers of harmonic and pulse signals, respectively, the outputs of which are connected to the first and second information inputs of the managed switch, the outputs of which are connected to the information inputs of the voltage level conversion unit, the outputs of which are the outputs of the generator, and the control inputs of the amplifiers of harmonic and pulse signals controlled switch and output unit converting voltage levels are connected to the appropriate control in CPU moves, moreover, a stabilized power source comprises four nominal output voltage, the CPU is designed as a microcontroller P1c 18R2520 type, frequency synthesizer - type ΆΌ9834, amplifier pulse signals - such ί.Ό40106. and the harmonic amplifier is of the type OR37.

The essence of the technical solution is that the implementation of the proposed device as described above allows you to work in a wide range of frequencies at different voltage levels and time intervals of exposure to harmonic and / or pulse signals.

At the same time, by programming the work, you can set at the output any necessary frequency of harmonic (for example, sinusoidal) or pulsed (for example, rectangular) signals from 1.0 to 999000.0 Hz, as well as the exposure time, level and shape of the output signal.

Comparison with the closest analogue suggests that the criterion of "novelty" meets, and the lack of distinctive features in the analogs indicates compliance with the criterion of "inventive step". Preliminary tests confirm the possibility of widespread industrial use.

The drawing shows a functional block diagram of the proposed device.

Ν-frequency generator of harmonic and pulse signals contains the power control unit 1

- 1 012697, a stabilized power supply 2, the outputs of which are connected to the information display indicator 3, for example LCD display, central processor 4, equipped with a keyboard 5, 6 frequency synthesizer, harmonic amplifier 7, for example sinusoidal, signals, pulse amplifier 8, for example , the signals, the managed switch 9 and the output block 10 convert voltage levels. The first and second information outputs of the CPU 4 are connected, respectively, to the indicator 3 and the corresponding input of the synthesizer 6 frequencies, the first and second outputs of which are connected to the information inputs of amplifiers 7 and 8 of harmonic and pulse signals, respectively. The outputs of the latter are connected to the first and second information inputs of the managed switch 9, the outputs of which are connected to the information inputs of the output voltage level conversion unit 10, the output terminals of which are the outputs 11 and 12 of the generator. The control inputs of the amplifiers 7 and 8 of the harmonic and pulse signals, the controlled switch 9 and the output voltage level conversion unit 10 are connected to the corresponding control outputs of the central processor, respectively.

The stabilized power supply 2 contains four output voltage ratings: +5, -8, +15 and -15 V. The generator is equipped with an induction sensor 13 with the possibility of connecting to the central processor 4. At the same time, the design of the induction sensor 13 is adapted to be mounted inside the coil of a ferromagnetic plate 14 types of the famous crystal applicator prepared with the help of the Stella-1 EHF-IR therapy device (see Methodical Recommendations No. 99/91 of the Ministry of Health of the Russian Federation "Use of background resonant radiation therapy m for the relief of pain in neurovertebral diseases, Moscow, 1999 p.6, 7) with the recording on it of the frequency characteristics of homeopathic remedies. The power management unit 1 is equipped with a power button 15 and supply terminals 16-1 and 16-2 ± 12 V.

The central processor can be made in the form of a microcontroller of the type P1C 18E2520, and the frequency synthesizer can be of the type LE9834. the amplifier of pulse signals is of the type SE40106, and the amplifier of harmonic signals is of the type OR37. Managed switch 9 can be performed on a transistor and a relay, and the output unit 10 conversion voltage levels can be made in the form of a scalable amplifier with external control gain. The central processing unit 4 may be provided with additional memory 17.

Device operation

When you turn on the power by pressing button 15 on the four outputs of the stabilized power source 2, four output voltages appear: +5, -8, +15 and -15 V, which are fed to the corresponding blocks.

In various studies, it is necessary to change the level of the frequency range, the shape and level of the output harmonic and / or pulse signals, as well as the setting of the operating time.

To do this, using the keyboard, install one of the required modes of operation of the central processor 4, and after programming is completed, the “START” key is pressed, after which information and control signals are received from the central processor 4 to the corresponding blocks.

So after receiving information on the synthesizer 6 frequencies, the latter generates a predetermined frequency of signals that arrive at amplifiers 7 or 8 harmonic or pulse signals, and from them to a controlled switch 9, at the output of which a signal of the form that was set during programming appears. Switch 9, depending on the control signal from the central processor 4, passes one of the selected types of signals to the output voltage level conversion unit 10, which, depending on the control signal from the central processor 4, generates output signals of a certain level: 5 or 10 V, coming to the outputs 11 and 12 generators to which a biological object can be connected via hand or foot electrodes. All information is reflected in the indicator 3.

It should be noted that the presence of an induction sensor 13 with a ferromagnetic plate 14 allows the impact on a biological object of pulsed signals with frequency characteristics of various homeopathic remedies.

Thus, in the proposed technical solution is achieved technical result.
