Description

The utility model relates to the field of radio engineering, in particular to signaling devices, call and communication devices (signal transmission), visual or tactile signaling systems intended for the hearing impaired and the deaf, based on the use of electrical transmissions.

Known intelligent doorbell, consisting of: at least one main module and at least one bell button module, including a wireless transmitter for sending a coded call signal to the main module, the main module consists of: a microcontroller unit; a wireless connection unit associated with the microcontroller unit, wherein the wireless connection unit is capable of two-way communication with an external device; a memory unit electrically connected to said microcontroller unit for storing one or more audio files that can be changed from an external device; a call signal receiver associated with the microcontroller unit; a noise level sensor associated with the microcontroller unit; a sound reproduction unit associated with the microcontroller unit and containing an audio file decoder with at least one speaker module (Patent No. 2351990 RU. Publ. 10.04.2009).

However, the well-known intelligent doorbell has a complex design predetermined for loading various melodies, which determines a relatively high cost, it is not intended for use in warning systems and sound signaling devices intended for the hearing impaired and deaf, and, therefore, does not fully meet the consumer's demands ( user).

Known sound signaling device with vibration and light indication for the hearing impaired and the deaf "Pulsar-3", designed to inform people with hearing impairment about the presence of sound signals: intercom, telephone, doorbell, crying child and others, as well as for the ability to transmit the call signal manually from the call button of the transmitter. To test the operation of a transmitter connected to a dedicated network, it is enough to press the call button and the transmitter simulates the call signal of this network. At the same time, the indication LED lights up, confirming the transmission of the signal ("Sound signaling device with vibration and light indication for hearing impaired and deaf people" Pulsar-3 ". Operation manual SEFK.464512.003 RE. Passport SEFK. 464512.003 PS). The set (composition) of the signaling device includes several specialized transmitters connected by cable with a specialized network to fix the presence of a device specialized for each network (intercom, telephone, doorbell, crying baby, etc.) signal and transmit it to the user on the air to a wireless receiving device. A dedicated transmitter consists of a housing, a housing cover and a cable for connecting the transmitter to a specific dedicated network (intercom, telephone, doorbell, crying baby, and others). The body is made in the form of a quadrangular pyramid with rounded edges. On the side surface of the case there is a socket for connecting the plug of the cable connector located at one end of the cable, and terminals for connecting the cable to a network specialized for each device (intercom, telephone, doorbell, crying baby and others) at the other end. On the housing cover there is a test call button and a hole for indicating the glow, as well as a pictogram for identifying the purpose of the transmitter. Inside the case there is a board with an electronic circuit of the transmitter and a battery, electrically connected to the connector socket.

The disadvantages of this technical solution are the need for a large number of specialized transmitters in the set of the sound signaling device, due to the lack of their versatility, and, consequently, its relatively high price and insufficient complete satisfaction of the consumer (user) needs.

The closest technical solution is a doorbell transmitter for a warning system (Patent RU No. 176073, IPC G08B 7/06, priority dated 09/04/2017), containing: a housing, a microcontroller and a radio module. The body is made in the form of a quadrangular prism with rounded edges. In this case, the base of the body, made in the form of a rectangular plate, is connected to a hollow cover equipped on the upper surface with a call button and an opening for indicating the glow of the LED. In addition, an electronic circuit is placed inside the housing on the base, in which parallel and series connection of elements with a power source is used. In this case, the following are connected in series: a battery, a call button, a microcontroller, a radio module and an antenna. And connected in parallel: a battery, a microcontroller and a radio module. In this case, the antenna is built-in.

The disadvantages of this technical solution is the lack of versatility, which leads to the need for a large number of specialized transmitters in a set of various devices of rehabilitation equipment, for example, a warning system, a sound signaling device, etc. The lack of their universality leads to its relatively high price and the price of devices for rehabilitation equipment, which means that it does not fully satisfy the needs of the consumer (user).

The technical result of the utility model is the creation of a universal transmitter for rehabilitation equipment, which makes it possible to reduce the labor intensity of its manufacture by reducing the nomenclature and increasing the serial production, which makes it possible to reduce the cost of the transmitter and rehabilitation equipment with its use and, thereby, to more fully satisfy the needs of the consumer.

The technical result is achieved by the fact that in a universal signal transmitter for a warning system containing a housing made in the form of a quadrangular prism with rounded edges and a cover, the housing has a connector socket, to which a cable is connected through a connector plug. The other end of the cable has terminals for connecting to the monitored signal source. The lid is equipped on its upper surface with a call button and a LED installed in the hole in the lid to indicate the glow. In addition, an electronic circuit is located inside the case at its bottom, which contains: a battery, a microcontroller, a radio module, a call button and an antenna. In this case, the antenna is built-in. The socket of the connector is electrically connected through the constant part of the resistive voltage divider circuit to the analog-to-digital converter as part of the microcontroller, which is combined with the radio module into one microcircuit. The other, variable part of the resistive voltage divider, which determines the presence and magnitude of the voltage supplied to the analog-to-digital converter as part of the microcontroller, is the signal sensor of the controlled source. It is located in the cable plug, which has a pictogram indicating the source to be monitored.

Also, a universal signal transmitter for a public address system can use one cable with a set of different plugs, with corresponding pictograms, electrically connected to the cable at one end and a set of terminals electrically connected to the cable at the other end to connect to the monitored signal source.

The electrical connection of the connector socket through the constant part of the resistive voltage divider circuit with an analog-to-digital converter as part of the microcontroller makes it possible to create a universal transmitter for rehabilitation equipment, which makes it possible to reduce the labor intensity of its manufacture by reducing the nomenclature and increasing the serial production.

Combining a microcontroller with a radio module in one microcircuit allows to reduce the labor intensity of its manufacture, and, therefore, to reduce the cost of the transmitter and rehabilitation equipment with its use and, thereby, to more fully satisfy the consumer's needs.

The presence of another variable part of the resistive voltage divider, which determines the presence and magnitude of the voltage supplied to the analog-to-digital converter as part of the microcontroller, which is the signal sensor of the controlled source and its location in the cable plug, which is equipped with a pictogram indicating the controlled source, allows you to create a universal transmitter that can be used with a set of cables with various signal sensors of controlled sources (intercom, doorbell phone, etc.) in the plug, which will reduce the labor intensity of its manufacture by reducing the nomenclature and increasing the serial production, allowing to reduce the cost of the transmitter and rehabilitation equipment with its use, and, thus, more fully satisfy the needs of the consumer.

Instead of a set of cables, one cable can be used with a set of different plugs, with corresponding pictograms at one end and a set of terminals for connecting to a monitored signal source (doorphone, doorbell phone, etc.), which further increases versatility and, thereby, reduces cost.

The utility model is illustrated by drawings.

Example 1. A universal signal transmitter for a public address system measuring 82 × 44 × 18 mm, weighing 35 g, containing a housing 1 made in the form of a rectangular prism with rounded edges and a cover 2. The housing 1 has a socket 3 of the jack 3.5 stereo plug ", to which cable 4 is connected via plug 5 of the" Jack 3.5 stereo plug "type connector, and at the other end of cable 4 there are terminals 6 for connecting to a controlled signal source 7, for example, to" Intercom ". The cover 2 is equipped on the upper surface with a call button 8, a yellow LED 9, as the most easily perceived by the user (patient), installed in the hole 10 in the cover 2 to indicate the glow. Inside the housing 1, at its bottom 11, there is an electronic circuit 12, containing: a battery 13 - a CR 2032 battery with a voltage of 3 V, a microcontroller 14, a radio module 15, a call button 8 and an antenna 16. In this case, antenna 16 at a frequency of 433.92 MHz is made built-in. Socket 3 of the Jack 3,5 stereo plug is electrically connected through the constant part of the circuit 17 of the resistive voltage divider 18 with the analog-to-digital converter 19 as part of the microcontroller 14, which is combined with the radio module 15 into one microcircuit 20 (type PIC12LF1840T39A-I / ST), another the variable part 21 (a, b, c) of the resistive voltage divider 18, which determines the presence and magnitude of the voltage supplied to the analog-to-digital converter 19 as part of the microcontroller 14, is a signal sensor of the controlled source 7, located in the plug 5 of cable 4, which is equipped with a pictogram 22, indicating the monitored signal source 7, for example, "Intercom".

The device works as follows.

To check the functionality of the universal transmitter, the user presses the call button 8. The signal is transmitted to the microcontroller 14, after modulation is transmitted through the radio module 15 to the antenna 16. In this case, the consumer sees through the hole 10 on the top surface of the cover 2 an indication of the call glow, i.e. luminescence of LED 9. During the operation of the transmitter, the circuit elements are recharged by means of battery 13. To reduce interference during signal transmission, the microcontroller and the radio module are combined into one microcircuit 20 (type PIC12LF1840T39A-I / ST, in one case).

When a monitored signal source 7 ("Intercom", "Telephone", "Doorbell", etc.) is connected to the network by selecting the appropriate sensor used (variable part 21 (a, b, c) of a resistive voltage divider 18) located in the plug connector 5, depending on the presence and magnitude of the voltage, recognizes the source of the monitored signal 7. The principle of operation of determining the type of sensor is based on the operation of a resistive voltage divider (resistors R _const. , R _x ). At the input of the microcontroller 14 (the microcontroller input is configured as the input of the analog-to-digital converter ADC), depending on the value of the resistance R _const. »R _x and voltage Vdd on the CR 2032 battery (Vdd), a certain voltage is formed, determined by the formula

U _ADC = (Vdd × R _x ) / (R _const. + R _x ), where:

Vdd - supply voltage;

U _ADC - voltage obtained as a result of division by resistors R _const. and R _x .

For each type of sensor, its own voltage is formed:

Doorbell sensor U _ADC = 0; R _x = 0.

Intercom sensor U _ADC = Vdd / 2; R _x = R _const .

Phone sensor U _ADC = Vdd; R _x = 0 (not installed).

The microcontroller 14, having determined the voltage value at the ADC input, assigns the appropriate name to the sensor, and when the sensor is activated, it sends the corresponding signal to the radio module 15, which, in turn, sends the radio signal to the air via the antenna 16.

The proposed utility model of a universal signal transmitter for a warning system is simple in design. The proposed utility model makes it possible to reduce the cost of the transmitter, by reducing the labor intensity of manufacturing by increasing the number of manufactured transmitters (increasing the serial production), and also to reduce the cost of rehabilitation equipment by reducing the number and range of transmitters in the product of rehabilitation equipment.
