FIELD: railway transport.
SUBSTANCE: invention relates to equipment of passenger cars. A complex of electrical equipment of a passenger car includes a control panel containing a central controller connected to subordinate microcontrollers designed to control actuators located in passenger car premises. The central controller contains two hardware ports for serial connection to subordinate microcontrollers to form a single continuous path for data transmission, similar to a ring. The central controller is made with the possibility of logical selection of the optimal port for receiving/transmitting data. Each subordinate microcontroller contains at least two hardware ports for communication with other microcontrollers and/or the central controller and is made with the possibility of retranslation of received signals.
EFFECT: expansion of the functionality of controlling electrical equipment of a passenger car and increase in the reliability.
