FIELD OF TECHNOLOGY

The invention relates to the field of medical technology, in particular to devices that transmit signals, namely transmitters having structural elements and electrical circuits, designed to replace direct auditory perception with another type of perception in people with hearing impairments.

BACKGROUND OF THE INVENTION

It is known a signal-triggering device with a radio channel warning, including a radio transmitter (ROP), comprising a transmitter, a microprocessor, a battery and a battery discharge control unit, in which the RPS is made in the form of a radio module (RM), is placed in a housing, mounted on a signal-starting device, for example USP-101, and is electrically connected to it. A receiver has been introduced into the RM, forming, together with the transmitter, a two-way communication channel intended for receiving / transmitting signals from / to the control panel and connected to the microprocessor input / output, an optocoupler, a voltage doubler in series according to the Natura circuit with its storage capacitor and a voltage converter DC / DC, and the input of the voltage doubler is connected to the output of the signal-starting device, the second output of the voltage doubler is the second output of the proposed device and is designed to connect with a fire extinguishing module, the output of the DC / DC voltage converter is connected to the radio channel and the second input of the microprocessor, the optocoupler output is connected to the third input, the optocoupler input is connected to the first output of the voltage doubler; signal-triggering devices, as well as polling a radio module to check for the presence of a communication channel (Patent N ° 148903RU. Publ. 12/20/2014).

However, the voltage converters used in the known device, lead to interference with other devices of the system.

Known hearing system containing at least two hearing aids HG-R, HG-L, spatially separated from each other and designed for wireless communication with each other. Each hearing aid is equipped with a transceiver that includes an inductive receiver and a digital Broadband Pulse Transmitter. A base station BG is provided, which is structurally separated from the hearing aids and is capable of transmitting a message from one of the hearing aids to another. The base station has an inductive transmitter (TX) for transmitting to hearing aids and a broadband receiver (RX) for receiving from hearing aids (Patent Ns JP4708390 (B2). Publ. 2011-06-22).

However, the known system is intended only for use in conjunction with hearing aids operating on an induction principle that does not allow for a range of work outside one room (the wall for a known system is an insurmountable obstacle) configured to provide wireless communication using a pulse transmitter, and does not allow reaching a radio signal of a sufficiently high frequency overcoming insurmountable obstacles (walls).

A device and method are known for sending a medical assistance call signal to a selected employee (Patent N ° 2638272RU. Publ. 12.12.2017), in which the router contains a warning signal transmitter for sending a warning signal to the selected employee. The alert signal transmitter is configured to search for the corresponding mobile device and send it an alert signal to this mobile device. The alert transmitter sends the alert signal wirelessly through an antenna, including an SMS message.

However, the transmitter in the known invention is intended to transmit only a warning signal and is not a universal device designed for its use in other situations. In addition, it is impossible to connect various sensors to the known transmitter to inform the user not only about the call signal, but also about other signal sources: doorbell, doorphone, telephone, etc.

A known transmitter containing an anode power source, a microwave amplifier, the third input of which is connected to the first output of the collector power source, a high voltage stabilizer, the output of which is connected to the input of the anode power source, a modulator and voltage divider. To reduce the noise level of the transmitter at various pulse durations, wells in a wide range of carrier frequencies, the first and second amplifiers, an automatic gain control device, and the first and second filters are introduced. Second exit the collector power source is connected to the fourth input of the microwave amplifier, the first input of the first amplifier is connected to the output of the first filter and the output of the voltage divider. The input of the voltage divider is connected to the output of the anode power source, which is also connected to the input of the first filter, the input of the collector power source, the input of the modulator and the first input of the microwave amplifier. The output of the modulator is connected to the second input of the microwave amplifier, the output of the second amplifier is connected to the input of the high voltage stabilizer, the input of the second amplifier is connected to the output of the first amplifier, with the input of the automatic gain control device and the input of the second filter. The output of the second filter is connected to the second input of the first amplifier and the output of the automatic gain control device (Patent .N 1 14573RU. Publ. March 27, 2012).

However, the known transmitter is not intended for use in warning systems for people with hearing impairments. It should be noted that in the known construction, radio tubes were used, which require a lot of energy and protection against destruction with insignificant mechanical loads (shock), and therefore the known product cannot be used as a mobile (user-worn) device.

A video transmitter is known in which signal processors are disclosed for allowing transparent, simultaneous transmission and reception of a data signal in a video signal band. The signal processor in the transmitter rasterizes the data with the data at a horizontal scanning speed and modulates the data with the data transmitter with a non-integer multiple horizontal scan chain, the intensity is obtained of an alternating frequency. Data is transmitted during the active part of the video of each line (Patent No. 5,387,94lUS. Publ. 07.02.1995).

However, the known solution is not intended for use in warning systems due to the presence of elements that allow you to receive a video signal. In addition, it has a voluminous and complex electronic microcircuit using video technology, which is redundant for the claimed device and leads to unreasonably high costs for the purchase and maintenance of this type of equipment.

A known integrated circuit design for a communication system with a wireless hearing aid, including a battery-powered transceiver unit worn in the immediate vicinity of the user's ear, and a compact battery-powered transmitter / receiver unit, worn or located in close proximity to the user. The basis of the set of integrated circuits is the optimization of size, speed, power and manufacturability for a personal wireless audio communication system using reflective transmission technology. Consideration of the power and speed of the circuit is designed to place the radio frequency reflective transmission of the wireless audio signal in the immediate vicinity of the user. The transceiver and receiver of the system are designed to switch between certain transmission states in order to facilitate quick switching between the first mode in which the transmitter transmits to the receiver and the second mode in which the transceiver transmits to the receiver (Patent No. 5751820US. Publ. 12.05.1998).

However, the well-known integrated circuit design for systems is focused on an individual user and does not allow several people to be covered by an information signal. In addition, in the known design there are no receivers that provide alerts to several people. Such, for example: as a light receiver, attracting people's attention with bright flashes of light and reflecting a specific signal source on the information display in the form of text and a graphic image (pictogram).

A known radio transmitter, consisting of a quartz oscillator, a controlled oscillator and an output oscillating system, in which a power divider is connected between the controlled oscillator and the output oscillating system, the second output of which is connected in series with a mixer, a low-pass filter, a frequency-voltage capacitor converter and a differential amplifier, moreover, the output of the latter is connected to the control input of the controlled oscillator, the second input to the output of the potentiometer, a second mixer input connected to the output of the quartz oscillator (Patent No2H23 l5RU. Publ. 27.05.1998 g).

However, the known radio transmitter is not intended for public address systems. In addition, the well-known source of patent documentation presents only a structural diagram without its relationship with the design of an external device that is easy to use. It should be noted that in the known design it is not possible to connect the transmitter to signal sources informing about the event and, as a result, it cannot be a transmitter of warning systems. A known doorbell transmitter for a warning system, comprising a housing, a microcontroller and a radio module, in which the housing is made in the form of a quadrangular prism with rounded ribs, the base made in the form of a rectangular plate connected to a hollow cover equipped with a call button and a hole on the upper surface to indicate the glow, in addition, an electronic circuit is placed inside the housing on the base, in which a parallel and serial connection of elements with a pit source is used In this case, they are connected in series: a battery, a call button, a microcontroller, a radio module and an antenna, and in parallel are connected: a battery, a microcontroller and a radio module, while the antenna is built-in (Patent No. 176073RU. Publish. 12.27.2017).

However, the well-known doorbell transmitter for public address systems has limited functions in the ability to transmit information from various sources and increase the clarity of its identification in the ambient background noise. In addition, the well-known design provides only one option for event notification - this is a doorbell, since there is no duplication of the signal that attracts the user, there is only acoustic (sound) and the inability to attract attention with bright flashes of light.

SUMMARY OF THE INVENTION

The objective of the present invention is to provide a convenient and simple device for use in public address systems designed for people with disabilities by attracting the user's attention with flashes of light.

New in the claimed transmitter is the ability to connect multiple sources of the information signal. Such as acoustic and electric. For the acoustic signal, both built-in and external microphones are used. For electrical information signals, special sensors are used with the use of galvanic isolation between the signal source and the transmitter.

The voltage on the information lines can reach life-threatening voltage of 220V. Galvanic isolation using optocouplers built into the sensors ensures the safety of the user during operation of the device.
