The invention provides a foot protection device of a multi-car intelligent parallel elevator and a control method of the foot protection device, the elevator comprises a control system, cars, the foot protection device and a position monitoring device for monitoring whether the cars are located in a door area or not, the foot protection device comprises a foot protection plate, the foot protection plate can be lowered to one end to be connected with a car bottom, and the other end of the foot protection plate overhangs downwards. The control method comprises the steps that when a car stops at a non-flat layer of a door area, if a car door of the car needs to be opened, the state of a toe guard needs to be detected firstly, and if the control system receives information that the toe guard is in a folded state, the control system controls the car door of the car to be kept closed and gives an alarm; and when the control system receives the information that the toe guard is in the put-down state, the control system controls the car door of the car to be opened. According to the invention, people in the car are prevented from falling into the hoistway when climbing out of the car, the control method is simple and easy to realize, and can be combined with an original control system of the elevator to realize intelligent operation and intelligent protection of the foot protection device.
