In this case, according to the invention, the central controller is connected to the local train network.

At the same time, according to the invention, the central controller is connected to a display for displaying information about the state of electrical equipment and emergency situations, equipped with a touch screen for entering control commands to ensure the functioning of the actuators of the car.

At the same time, according to the invention, a communication and signal interface converter (CISS) is used as a co-slave microcontroller, which is made with the possibility of increasing the number of connected actuators and/or signals.

At the same time, according to the invention, the subordinate microcontroller is connected to a display for displaying information about the state of electrical equipment and emergency situations, equipped with a touch screen for entering control commands to ensure the operation of actuators in separate rooms of the car.

In addition, the proposed communication architecture of subordinate microcontrollers that are part of the electrical equipment complex, as well as the use of a compartment comfort unit (CCU), made in the form of a touch screen display with the ability to control and manage the functions of a passenger car compartment, allows you to expand the possibilities of individual control of equipment in each compartment. , which increases passenger comfort due to the possibility of individual adjustment of equipment parameters and enhanced functionality, while maintaining the possibility of centralized control of devices, and also allows you to analyze the received data on the technical condition of the device and complex components based on sensor readings and accounting for operating time.

Also, the distribution of the components of the control system in the internal space of the car ensures their compact placement, since the number of communication lines between the devices and the central controller has been significantly reduced, therefore, it is possible to increase the functionality in the limited space of the control panel with the central controller and the car space as a whole.

Brief description of the drawings

The invention is illustrated by a description of a specific example of its implementation, where in Fig. 1 shows a functional diagram of the electrical equipment complex of a compartment passenger car. However, this example does not limit the scope of protection of the invention, since it can also be used on other models of passenger cars, for example, reserved seat.

Implementation of the invention

The electrical equipment complex of the passenger car contains a control panel for the car equipment located in the conductor's compartment. The control panel houses the system for visualization and control of the car systems (hereinafter referred to as VUSV, item 1), including a device for monitoring the condition and control of the car equipment, containing a central control controller, means of connecting to the local train network and a display for displaying information about the state of the equipment, emergency situations. The display is equipped with a touch screen for entering control commands to ensure the functioning of the carriage equipment, which consists of sequentially connected to each other using a digital communication line (pos. 2) with subordinate microcontrollers designed to control actuators located in the interior of the passenger car.

The central control controller SVUSV contains two hardware ports for connection via a digital communication line (pos. 2) with subordinate microcontrollers and / or control actuators, including subordinate microcontrollers. The central control controller is configured to logically select from its two ports the optimal port for receiving / transmitting data from subordinate microcontrollers.

In the exemplary embodiment of the invention, the subordinate microcontrollers comprise:

1) compartment comfort unit (hereinafter BKK, pos. 3), central speaker system (hereinafter referred to as CAC, pos. 4), communication and signal interface converter (hereinafter referred to as KISS, pos. 5) located in each compartment passenger car;

2) KISS (pos. 6), located in the toilets;

3) a set of information car (hereinafter referred to as KIV, pos. 7) and KISS (pos. 8), located in the corridor of the passenger car.

Each subordinate microcontroller is either included in the design of the actuator, or is an independent element designed to integrate devices with standard communication interfaces (CAN, RS-485, LIN, etc.) into the car control system and input-output of analog and discrete signals for control/analysis of the state of external equipment that does not have its own microcontroller. In our example, independent subordinate microcontrollers are BKK (pos. 3) and KISS (pos. 5, 6 and 8).

BKK (pos. 3) is a subordinate microcontroller in the form of a touch screen display, which controls the following functions of a passenger car compartment:

- adjustment of illumination;

- temperature control;

- adjusting the volume of notifications (except for emergency notifications);

- informing passengers (toilets occupancy, nearest station, parking time, etc.);

- interaction with train services (conductor / dining car / train leader).

KISS (pos. 5, 6 and 8) is also a subordinate microcontroller and differs from BKK in the absence of a user interaction interface made in the form of a touch screen, and is used in technical rooms, such as a corridor, a toilet, etc., in which there is no the need for interaction with the passenger (adjusting the volume, temperature, etc.). Also, KISS (pos. 5, 6 and 8) can be used to increase the number of connected actuators and / or signals in rooms where BKK and / or KISS are already installed.

DAC (pos. 4) is an executive device that contains a subordinate microcontroller and is designed to receive audio content in digital format via communication channels, designed to provide sound, voice or musical notification to passengers:

- emergency - with the highest priority for the entire train or wagon;

- information - for the entire train or wagon;

- individual - for a specific compartment.

The DAC (pos. 4) allows you to perform notification both in automatic (emergency and fire notification, notification of stops in accordance with the traffic schedule) and in manual mode (microphone of the conductor / head of the train), and also be used as part of the intercom system "passenger -conductor", "passenger-head of the train"

KIV (pos. 7) is an actuating device containing a subordinate microcontroller and is designed to display the information data received from the central control controller SVUSV (pos. 1) in text and graphic form on information displays, such as displaying the route of movement, the current location on map or traffic pattern, as well as storing information data and generating data placement templates.

Each slave microcontroller contains at least two ports for communication with other microcontrollers and is configured to relay received signals to another microcontroller. Each subordinate microcontroller provides the ability to control the operation of the executive device and is equipped with means for storing the settings of the current operating mode of the executive device. In this case, the central control controller SVUSV (pos. 1) is connected in series using a digital communication line (pos. 2) with the subordinate microcontrollers of the actuating devices.

The microcontrollers are connected to each other using a digital communication line (pos. 2), forming, together with the central control controller, a single continuous path for data transmission, similar to a ring.

Other executive devices equipped with microcontrollers can be used as part of the complex:

– installation of fire alarm and fire extinguishing (UPSPT),

– intercarriage wireless communication system (MSBS),

- a set of control of electrical equipment and diagnostics of the car (KUEDV),

– intelligent telematic control system (ISTK),

- axle box control complex (KKNB),

– car power supply control unit (BUEV),

– wagon access control system (VSKD),

– sound broadcasting system (STZ),

– video surveillance and registration system (SVNR),

– system of protection against blocking of wheels (SZBK),

- system of purchase control of the temperature level (SPRUT),

– mobile information, communication and configuration system (MSISK),

– digital lighting system (DSO).

The principle of operation of the complex with a ring topology of communication is that the transmission / receipt of signals over the communication line (pos. 2) is organized by the central control controller located in the SVUSV (pos. 1) as follows: one connection provides signals in one direction (for example , clockwise) and the other link in the opposite direction (counterclockwise). One of these connections can be conditionally considered a reserve one, because in normal operation, only one link is used. The initiator of the exchange in the system is the central control controller in the SVUSV (pos. 1), which sends a request (data packet) to the slave microcontroller through one of its ports (for example, clockwise). All microcontrollers in the ring have repeaters in their composition (a data packet received from one port is transmitted unchanged to another). If no response is received by the central control controller, then it repeats the exact same signal through the second port (counterclockwise). Thus, in case of damage to the digital communication line (pos. 2) in an arbitrary place of the ring or failure of one of the repeaters (an integral part of each subordinate controller), the connection between the devices will not be broken.

The invention is not limited to the example of its implementation and use. At the request of the customer, it is possible to add or remove actuators to the complex, depending on the needs and model of the car.
