Exterior features of the system, "the alternator rectifier" autonomous vehicle
In’kov Y., Fadeikin T., Bredikhina J.A mathematical model of the system "synchronous generator - rectifier", which is the input element of the electric system of an autonomous vehicle. In the output unit of the system installed stand-alone inverters and voltage actuators AC motors. Knowledge of the external characteristics of the output link allows reasonably determine the voltage at the input of autonomous inverters and thereby implement the law of frequency control of AC motors.

Bestemyanov P., Zakharov D.In the research work there is presented output voltage of the locomotive coil KPU-1 experimental dependence on signaling current frequency. Values of parasitic capacity of coils and loss resistance are calculated. There were received matched output voltage of locomotive coils dependences on signaling current frequency at a constant transmitter power.
Keywords: the automatic cab signaling, locomotive coils, rail line control signal, automatic block signaling, current in the rail line.The development of vision systems for railway transport
Mikhailov V., Ovcharov I.On examples of specific developments shows the history and prospects of the development of railway equipment and machine vision systems in different ranges of the electromagnetic spectrum.
Keywords: machine vision, railway transport, arts television, infrared receiver, radio vision.
