The invention discloses a high-speed construction hoist electric control system based on PLC control and a control method thereof. The high-speed construction hoist electric control system based on PLC control comprises a suspension cage and a bottom cage electrical box, wherein an electric control cabinet is fixedly installed in the suspension cage, a frequency converter is fixedly installed at the bottom end in the electric control cabinet, a control assembly is fixedly installed at the top end in the electric control cabinet, a contact assembly is fixedly installed at the bottom of the control assembly, an anti-falling assembly is fixedly installed at the bottom of the contact assembly, and a circuit breaker is fixedly installed at the top end in the bottom cage electric box. Through a driver fixedly installed on one side of the cage and the frequency converter fixedly installed at the bottom end of the interior of the electric control cabinet, the frequency converter controls the driver formed by connecting three sets of motors in parallel in an open-loop mode in a multi-segment line VF control mode, the speed of a construction hoist can be increased by controlling the driver through the frequency converter, the construction efficiency of the construction hoist is high, and the construction quality and progress are improved.
