The task to be solved by the claimed technical solution is to expand the functionality of the passenger information system by providing information in English and Arabic and broadcasting audio content, both on one car and on all cars at the same time without installing the control equipment of the set in the head wagon.

The problem is solved in the following way.

A set of equipment for informing passengers on passenger railway cars, containing a touch computer in the conductor compartment, which is connected via an RS485 or CAN communication line to the climate control unit of a passenger car and has discrete inputs for receiving discrete signals from other (sub)systems of the car / train, through a relay circuit notification control is connected to an audio amplifier, via an Ethernet line to a switch that transmits information between the components of the kit via an Ethernet line, which is connected with one output to a touch panel computer, and other outputs to panel computers located in the passenger compartment, and through a relay control circuit for notification with an audio amplifier , which is connected to the car loudspeakers through a relay control circuit for notification, a DC converter that supplies a constant voltage of 24V to the components of the kit through a relay control circuit for notification.

A set of equipment for informing passengers is installed on each car in the train, excluding the head car (locomotive). At the same time, the operation of the kit can be extended both to one car in which it is installed, and to all cars in the train, by pressing the corresponding button on the touch panel computer.

The block diagram of the CAIP is shown in figure 1.

The DC converter is designed to power the switch and relay.

The touch panel computer is intended for:

- conversion of data from the CAN line or RS485 line of the air conditioner into data for the Ethernet line of the kit;

- control of the KAIP set by means of a touch screen;

- output of diagnostic information;

- conversion of information of a discrete line, and its output to a panel computer.

The panel computer is designed to display visual information for passengers

The audio amplifier is designed to amplify the audio output from the touch panel computer and microphone.

The microphone is designed to transmit the voice messages of the car conductor to the loudspeaker line

The loudspeaker is designed to output audio information in the passenger compartment. The layout of the loudspeakers is shown in figure 2.

The switch is designed to transfer information between the components of the CAIP via the Ethernet line.

The device and operation of KAIP.

Functionally, CAIP is divided into two functional parts:

- audio information;

- visual information through the panel computer.

To obtain climate data, the kit is connected to the car's climate control system via CAN or RS485 lines.

The system receives information about the occupancy of the toilet via the DIO line, from the toilet door contactors.

The audio signal is transmitted via the UIC line.

Control and data exchange between the system components is performed via the Ethernet line.

The CAIP is switched on by supplying power to the components of the set from the power supply circuits of the car

After power is applied, the system and application software (hereinafter referred to as software) of the kit components is loaded.

After the software download is completed, the kit goes into normal operation mode.

The transition of the CAIP to the normal operation mode after power supply is carried out in no more than 3 minutes.

The beginning of the work of CAIP in the regular mode is considered:

- the moment when the visual display of time and date appears on the panel computer;

- displaying the operating interface on the touch panel computer.

The CAIP is switched off by disconnecting the set from the car power supply circuits.

In the normal mode of operation of the kit, there are two modes of displaying information on the panel computer:

a) in English - time, day of the week, occupancy of the toilet, temperature inside the cabin, relative humidity inside the cabin, temperature outside the cabin (figure 3);

b) in Arabic - time, day of the week, occupancy of the toilet, temperature inside the cabin, relative humidity inside the cabin, temperature outside the cabin (figure 4).

When the kit enters the normal mode of operation, the information display turns on in the display mode according to figure 3.

Switching display modes occurs automatically, alternately, cyclically, after a configurable period of time.

If there is no communication with the air conditioner or if the value of the climatic parameter transmitted from the air conditioner via the CAN or RS485 line is incorrect, it will not be displayed.

The value of relative humidity is considered correct in the range from 0% to 100% inclusive.

The temperature value is considered correct in the range from minus 9°С to plus 99°С inclusive.

In normal operation mode, the touch panel computer displays a working interface (figure 5), which has the following information:

1 - display of toilet occupancy information;

2 - information about temperature and humidity;

3 - time;

4 - button to activate the microphone;

5 - button to activate the output of sound information through the jack;

6 - button to activate the output of sound information via USB;

7 - volume control;

8 - button for selecting the transmission of sound information to the car or train;

9 - service settings button.

The top field of the touch panel computer duplicates the information displayed on the panel computer, namely information about temperature, humidity, time, and toilet occupancy in two languages.

Before starting work with the touch panel computer, the operating mode of the device is selected. By default, the "This coach" notification mode for one car is activated; to activate the "This coach" mode, you must press the corresponding button 8.

In the "This coach" operating mode, the audio notification works only for this coach.

To activate the "Whole train" mode, you must press the corresponding button 8.

In the “Whole train” operating mode, the audio notification works for all cars of the train.

There can be only one touch panel computer in the "Whole train" mode. If the "Whole train" notification mode is activated in any car, then the activation of the "Whole train" mode in another car of the train is not possible, and the "Whole train" button on the screen of the touch panel computer will be lit in red. This blocks the ability to play audio files from "USB" and "Audio Input" (figure 5). The car staff will be able to notify only their car interior from a microphone.
