The invention relates to a turnout switch control system and control method based on a PLC (Programmable Logic Controller) and a touch screen, which are used for controlling and detecting a car stop mechanism, a switch mechanism, a 1 # lock pin mechanism and a 2 # lock pin mechanism of an overhead monorail turnout and realizing an inching control function and a simulated animation display function of one-button linkage and multi-level interface jump protection of the turnout. The control system is composed of a touch screen, a programmable controller, a frequency converter, a motor, a limit switch and an encoder. The method has the advantages that a guide type operation interface is adopted, operation is simple, and the probability of misoperation is reduced; a one-button linkage operation mode is adopted, the intelligent degree is high, and the reliability of the system is improved; thirdly, simulation animation views of all levels of operation interfaces of the touch screen restore the real running state of the equipment, so that an operator can control the running condition of the equipment conveniently; 4, a frequency converter of the switch mechanism adopts a basic positioning function technology, so that the operation precision of equipment is improved; and 5, the system is provided with a single-action mode of each mechanism, so that daily maintenance is facilitated.
