Work description

Control panel operation The electrical equipment of locomotive-hauled passenger cars is as follows.

In the current mode of operation, the second bidirectional communication line 1.5 of the control panel, namely from the local information network 3 of the car, receives data on the speed of the car, on the state of its equipment, including the system of lighting, air conditioning, sanitary equipment, heating, water supply and fire extinguishing. Data from the first bidirectional communication line 1.4 goes to the control and diagnostics controller 1.1, the protocol converter 1.8 and the visualization and control tool 1.2.

The control and diagnostics controller 1.1 monitors and controls the systems of the car through the system for collecting and transmitting information 1.3.

To turn on a certain consumer of the car (lighting, heating, air conditioning, ventilation, sockets, etc.), the operator, using the visualization and control tool 1.2, selects the operating mode of the equipment and turns on the electrical equipment of a certain consumer. In this case, the control signal from the visualization and control tool 1.2 via the second bidirectional communication line 1.5 enters the control and diagnostics controller 1.1 and the protocol converter 1.8. In the control and diagnostics controller 1.1, using the preinstalled software, the possibility of switching on the consumer is assessed for the absence of possible blockages (for example, a low battery level, fire, etc.), a control command is issued to the protocol converter 1.8.

In the protocol converter 1.8, the data packet is converted from the format of the information carriage network 2 to the format used in the data collection and transmission system 1.3. Further, the control packet of signals converted in the protocol converter 1.8 enters the motherboard 1.3.1. The motherboard 1.3.1 generates a signal to turn on the switching equipment and transmits it through the control port 1.3.3 to the low-voltage power supply and protection unit 1.6. The low-voltage power supply and protection unit 1.6 performs the appropriate commutation of the power supply lines at the terminal block 1.7. In this case, power is supplied to the power cables of consumers connected to the contacts of the terminal block 1.7

At the same time, a feedback signal about switching on the consumer is generated in the low-voltage power supply and protection unit 1.6, which is fed to the motherboard 1.3.1 through the expansion module 1.3.2. In the motherboard 1.3.1, a signal is generated to turn on the consumer, which is transmitted to the protocol converter 1.8. At the same time, the protocol converter 1.4 converts data from the format of the information collection and transmission system 1.3 to the format of the information wagon network 2, as well as to the format of the train information network 2. At the same time, the console operator has the ability to control the switching on of the corresponding consumer using the visualization and control tool 1.2.

Monitoring the condition of the equipment is as follows. An alarm signal (for example, about a decrease in the electrical insulation resistance of the car's circuits) from the insulation monitoring device located in the control panel goes to the motherboard 1.3.1 through the 1.3.2 expansion module. Further, a data packet is formed into the information collection and transmission system 1.3, including with an alarm signal and through the protocol converter 1.8 is converted into the format of the information network of the carriage 3 and through the second bidirectional communication line 1.5 it enters the control and diagnostics controller 1.1 and the visualization and control tool 1.2 ... In turn, the control and diagnostics controller 1.1, using the preinstalled software, ensures the transmission of signals to the first bidirectional communication line 1.4 and through port 1.9 to the information network 2 of the train, and also provides the formation of commands to turn off the electrical equipment until the malfunction is eliminated. The visualization and control tool 1.3 displays graphical information about the state of the car's electrical equipment.

In a similar way, the control panel operates under the influence of other alarm signals and deviations of the parameters of the electrical equipment of the car from the norm.

Industrial applicability

The utility model is developed at the prototype level. The remote control has been tested on an industrial stand. Tests have shown that the control panel makes it possible to use complexes of electrical equipment for passenger cars with systems of different architecture and data processing principles, which contributes to an increase in the functionality of the control panel, ensuring increased reliability.
