The invention provides an anti-decoding Bluetooth broadcast roller shutter door control method, and relates to the technical field of control, and the method comprises the following steps: S1, building a central end, and generating an algorithm library in the central end; S2, acquiring the algorithm library corresponding to the controller when the controller is accessed to the central end; S3, calculating a relation corresponding table of time and the algorithm library, and generating a key; S4, when the mobile terminal is accessed to the central end, judging whether a mobile terminal has thecontrol authority of the controller or not, if so, executing S5, otherwise, not executing the operation; S5, enabling the central end to send the key of the controller to the mobile terminal; S6, acquiring the real time, obtaining a corresponding algorithm in the algorithm library through the key, and performing the control and management of the controller through the algorithm. The anti-decodingBluetooth broadcast roller shutter door control method is good in safety, decoding can be effectively prevented, the risk that a wireless signal is intercepted to simulate door opening is effectivelyreduced, the control mode is novel, the method can be used in cooperation with an APP, and financial safety is guaranteed.
