Anti-decoding Bluetooth broadcast roller shutter door control method

Abstract

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.

Description

technical field [0001] The invention relates to the field of control technology, [0002] In particular, the present invention relates to an anti-deciphering bluetooth broadcast rolling door control method. Background technique [0003] At present, rolling shutter doors are widely used in warehouses, garages, shops, etc. The rolling shutter door cooperates with the ground lock through the rolling shutter door lock to lock the rolling shutter door so as to protect the finances inside the rolling shutter door. The opening and closing of the rolling shutter door are controlled by the motor controller above it. . [0004] In the existing motor controllers, the switching direction of the motor is switched by manually flipping the slide switch. For example, the level of the IO port of the motor controller is high / low, and the motor controller detects high / low level. Receive the door opening command to control the motor to run in the forward / reverse direction; when the slide swit...

AI Technical Summary

Problems solved by technology

[0006] However, the above-mentioned rolling door control method still has the following disadvantages: poor security, easy to be deciphered, there may be other people intercepting the door opening signal, and using a simulator to simulate the door opening signal, the rolling door can be opened illegally, financial security is not guaranteed
