Thermal lockout for a motor of a gate crossing mechanism
11486098 · 2022-11-01 · ·

Examples described herein provide a computer-implemented method for thermal lockout for a motor of a gate crossing mechanism. The method includes monitoring a motor current across a sense resistor of the motor. The method further includes determining a present thermal capacity unit (TCU) at a time interval based on the motor current across the sense resistor. The method further includes determining whether the motor is at a thermal limit by comparing the present TCU to an expected TCU. The method further includes responsive to determining that the motor is at the thermal limit, causing initiating a hard fault.

Direction control for a motor of a gate crossing mechanism
11472456 · 2022-10-18 · ·

Examples described herein provide a method for direction control of a motor of a gate crossing mechanism. The method includes providing, by a field-effect transistor (FET) driver, a first voltage via a high output to an open contact of a first relay and to a closed contact of a second relay. The first voltage causes a shaft of the motor to turn in a first direction. The method further includes providing, by the FET driver, a second voltage via a low output to a closed contact of the first relay and to an open contact of the second relay. The second voltage causes the shaft of the motor to turn in a second direction opposite the first direction.
