The utility model relates to a safety management control system. The safety management control system comprises a PLC (Programmable Logic Controller); the frequency conversion controller and the lifting motor are connected to the PLC through the frequency conversion controller, the PLC controls the lifting motor to work through the frequency conversion controller, the frequency conversion controller feeds back the working current value of the lifting motor to the PLC, the PLC judges whether the flexible door operates normally or not according to the working current value of the lifting motor, and if the judgment is abnormal, the PLC controls the lifting motor to work. If yes, the PLC controls the lifting motor to stop running; and the encoder assembly is arranged on the fixed pulley assembly and used for recording the stroke of a fixed pulley of the fixed pulley assembly, and the PLC obtains the height position of the flexible door body based on the stroke of the fixed pulley so as to prevent the flexible doo
