Abstract

An electronic controller for controlling a trolley pole switch is disclosed. The trolley pole switch switches the path of travel that an energy collector of a trolley pole takes through the trolley pole switch at a junction of power conduits diverging from the trolley pole switch. The electronic trolley pole switch controller includes a signal processing device and a power controlling device employed in tandem to control the frog solenoids of a trolley pole switch. The signal processing device detects and processes a plurality of modulated signals. Each modulated signal represents a request to switch the path of travel that the energy collector takes through the trolley pole switch to a desired one of the power conduits diverging therefrom. In response to each modulated signal, the signal processing device generates an intermediate command signal indicative of a command to supply power to the appropriate frog solenoid that effects the switch in the path of travel through the trolley pole switch to the desired power conduit. The power controlling device receives the intermediate command signal from the signal processing device and in response thereto supplies power to that frog solenoid. The frog solenoid energizes and therethrough compels the trolley pole switch to switch the path of travel that the energy collector will take through the trolley pole switch to the desired power conduit.
