The closest technical solution is an intercom with a touch screen and wireless communication (Patent RU 171655 U1, 06/08/2017, G08B 3/10, G10L 21/0356, G06K 9/00, G06F 3/041, H04H 60/91), consisting of devices for processing, storing and transmitting information, an information input-output module, a user identification module, an actuator control module and a subscriber communication module, and the information input-output module is a touch screen with the output of human-readable information and the ability to enter information directly on the screen by touch, which is used in conjunction with a microphone and speaker to receive and transmit audio information; the user identification module is a unique key identification device in at least one way; the actuator control module is an electrical switching device for controlling access restriction devices, as well as service devices; The subscriber communication module includes at least one wireless digital data transmission device that allows the use of standard digital devices, such as, for example, a smartphone, tablet computer or laptop, as subscriber devices for communication and control of the intercom using appropriate software.

The main disadvantages of the above-described technical solutions are insufficient dust and moisture protection and, as a result, a limited service life in a mode of increased operational load, the inability to use intercoms with gloves or mittens due to the lack of response (or difficulty in positioning) keystrokes at negative temperatures.

The technical result of the claimed utility model is to increase the dust and moisture resistance and, as a consequence, the service life, reliability and ease of use of the door station doorphone in gloves or mittens, while simultaneously realizing the possibility of its use in a wide temperature range.

To achieve the specified technical result, a doorphone doorphone panel is proposed, consisting of a control module, a communication module and an information input module, and the information input module is made in the form of a mechanical-capacitive keyboard, which includes the following elements: a front panel, a membrane with symbol values, light-scattering membrane, keyboard membrane, dielectric spacer and contact pads of the electronic board.

To ensure dust and moisture protection, a sealing gasket can be located between the membrane with symbol values and the light-scattering membrane, and LEDs can be equipped in the space between the dielectric gasket and the contact pads of the electronic board, providing backlighting of the keyboard buttons with the ability to change the color of the backlight and its intensity depending on the external illumination ... The control module controls the operation of the keyboard using a microcontroller, the logic elements of which constantly calibrate the pressing force (preventing false positives or pressing with force), processes keystrokes and determines the response to pressing (changes the key backlighting, starts the soundtrack).

The sealing gasket can be made of a silicone compound, or synthetic rubber compounds.

The front panel can be made of any metal alloy with fire-resistant, anti-corrosion properties or with a fire-resistant, anti-corrosion coating. The front panel contains a block for reading keys, in particular digital wearable keys.

The membrane with symbolic values can be made of an elastic refractory, anti-corrosion material, or from any metal alloy with fire-resistant, anti-corrosion properties, or with a fire-resistant, anti-corrosion coating.

The diffuser membrane can be made from a polymer compound (synthetic fiber) and allows the light of the LED backlight to be diffused for uniformity, and also allows for a rigid keyboard frame.

The keyboard membrane is made of a fireproof metal alloy. Its plane is used to change the capacitance, while the amount of deflection determines the pressing force, the area of the plate above the contact pad determines the factor of false triggering of both pressed and adjacent keys.

The dielectric spacer determines the distance and ensures its uniformity between the planes of the keyboard membrane and the contact pads of the electronic board. Made from synthetic polymer.

The electronic board with contact pads is made of fiberglass and is designed to register changes in capacitance when the keyboard membrane bends.

A special case of the implementation of the doorphone doorphone panel can be performed as follows: the doorphone doorphone panel 1 consists of a control module 2, a communication module 3 and an information input module 4, and the information input module 4 is made in the form of a mechanical-capacitive keyboard 5 with buttons containing in the corresponding sequence front panel 6, membrane 7 with symbolic values, light-scattering membrane 8, keyboard membrane 9, dielectric gasket 10 and electronic board 11 with contact pads 12. Between membrane 7 with symbolic values and light-scattering membrane 8, a sealing gasket 13 can be located, and in the space between the dielectric spacer 10 and the electronic board 11 can be equipped with LEDs 14. In addition, the door station of the on-door speakerphone 1 can be equipped with an information and / or display output module 15, and the control module 2 with a microcontroller capable of calibrating the force of pressing the buttons and false crap filter batting. Moreover, the information input module 4 contains a key reader 16, and the communication module 3 contains an audio-calling unit 17 (microphone with a speaker) and can be equipped with a video camera 18 and / or a device for reading and / or recognizing the visitor's biometric information. In this case, the sealing strip 13 can be made of silicone compounds, or compounds based on synthetic rubber.

The doorphone doorphone panel works as follows: first, the doorphone doorphone panel 1 is mounted near the entrance to the entrance of a residential building, office building, elevator shaft or lift and is connected via a control module 2 to executive electric lifting devices or an electrical locking device for opening doors, gates. Control module 2, communication module 3 and information input module 4 are structurally made in one housing. The subscriber can independently enter the protected area or premises using his key through the key reader 16. In turn, the visitor through the information input module 4, made in the form of a mechanical-capacitive keyboard 5, through the buttons establishes a two-way communication with the subscriber he needs. In this case, the visitor, pressing the buttons indicated by the symbolic values of the membrane 7, which is located under the front panel 6, acts through the light-scattering membrane 8 on the keyboard membrane 9, which forms a separate capacitive element (capacitor button) with a dielectric spacer 10 for each button. Thus, changing the capacitance of the capacitor buttons by mechanical pressing on the symbolic values of the membrane 7, the formation of a specific signal for a specific capacitor button through the contact pad 12 of the electronic board 11. Moreover, the control module 2 can be equipped with a microcontroller, which is carried out using a specific program-algorithm constant pressure calibration to prevent false triggering or too hard pressing of the buttons.

In addition, between the membrane 7 with symbolic values and the light-scattering membrane 8, a sealing strip 13 made of silicone or synthetic rubber compounds can be located, which ensures the sealing of the door station of the on-door speakerphone 1 from dust and moisture. In this case, in the space between the dielectric spacer 10 and the contact pads 12 of the electronic board 11, LEDs 14 can be equipped, which allow using the door station of the intercom 1 in dimly lit places or in complete darkness. Moreover, the calling panel of the on-door speakerphone 1 can be additionally equipped with an information and / or indication output module 15. Further, the subscriber receives a call to his transceiver device and establishes a two-way voice or audio-visual communication with the visitor through the audio-calling unit 17 (microphone with speaker) and / or video camera 18, including from the side of the receiving device. If the visitor receives permission to enter, the subscriber issues an appropriate command to open / lift the electrical actuators through the control module 2, as a result of which the visitor gains access to the protected premises or territory.

The specified technical result is achieved due to the fact that the keypad of the doorphone doorphone is implemented on the mechanical-capacitive principle of operation, on the one hand, which provides an increase in the service life and ease of use of the doorphone doorphone panel in gloves or mittens due to the design features of its buttons, on the other - increased reliability due to the absence of mechanical moving structural elements. In addition, the presence of a sealing gasket between the membrane with symbolic values and the light-scattering membrane ensures reliable and high-quality sealing of the doorphone doorphone panel from condensation and moisture, and the equipment of the doorphone doorphone panel with a keyboard backlight makes it possible to use it in dimly lit places. At the same time, the presence of a microcontroller with a specific program-algorithm for the control module of the door station of the on-door speakerphone, on the one hand, ensures the calibration of the pressing force on the buttons, excluding false alarms or too difficult pressing.

No technical solutions have been identified that coincide with the set of essential features of the claimed utility model, which makes it possible to conclude that the claimed utility model is consistent with such a condition of patentability as "novelty".
