Detailed Description
The following are specific examples of the present invention, and the technical solutions of the present invention are further described, but the present invention is not limited to these examples.
Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the modules and structures set forth in these embodiments does not limit the scope of the invention unless specifically stated otherwise.
The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
Techniques, methods, and systems known to those of ordinary skill in the relevant art may not be discussed in detail, but should be considered part of the authorization specification where appropriate.
Examples: as shown in fig. 1, which is only one embodiment of the present invention, an anti-hacking bluetooth broadcast rolling door control method includes the following steps:
s1: establishing a central end, and generating an algorithm library in the central end;
in general, a central terminal is established, that is, a server is established, or a data transmission terminal is established, and as the central terminal, a controller of the rolling shutter door and a mobile terminal for controlling the controller are connected to the central terminal for data exchange.
Algorithm library is a collection of rules of algorithm over time.
Of course, the algorithm library generated here may be one or a plurality of algorithm libraries, but once the algorithm libraries are a plurality of algorithm libraries, any two algorithm libraries must be different from each other.
S2: when the controller is accessed to the central end, an algorithm library corresponding to the controller is obtained;
when the controller is connected to the central end, that is, the controller receives the signal transmission of the central end to control, an algorithm library is allocated to the controller, the controller is connected to the central end through Bluetooth or wifi, the signals in a common warehouse or factory are poor, the connection is preferably carried out through Bluetooth, and the signal transmission between the controller and the central end does not depend on the network speed, so that the signal transmission can be carried out within a certain range.
Here, the controller is numbered when the algorithm library is allocated, and after the algorithm library is allocated, the controller number is recorded in association with the algorithm library corresponding to the controller.
It should be noted that if the central terminal generates only one algorithm library, all controllers connected to the central terminal share one algorithm library; otherwise, if the central side generates a plurality of algorithm libraries, each controller may share one algorithm library, or some controllers may share one algorithm library. However, the controllers are required to be numbered, and a plurality of controllers can be separated, so that the designated controllers can be controlled conveniently; and secondly, the corresponding algorithm library is conveniently read.
S3: calculating a relation corresponding table of time and an algorithm library to generate a key;
the key is a means for obtaining the relationship between the real-time and the zero time by taking a preset time as the zero point, and then calculating to obtain the algorithm corresponding to the real-time according to the law of the change of the algorithm in the algorithm library along with the time, which is called a key.
The predetermined time is settable and is not a unique value.
Even if all controllers share one algorithm library, the keys are different as long as the zero time set in the keys is different, and the passwords of the control algorithms of the two controllers are different at the current time; therefore, the probability of the same algorithm password appearing at the same time of the two controllers is infinitely reduced, even if the probability of the same algorithm password is very small, the algorithm password cannot be copied or expected, and the risk that an lawless person intercepts the algorithm password in a signal sent by the mobile terminal to perform simulated door opening is effectively reduced.
In summary, the algorithm libraries of the multiple controllers may be different, and even if the algorithm libraries of the multiple controllers are the same, the keys may be different, so that the algorithm passwords controlled by each controller in real time are different.
Of course, when step S3 is executed, the key is stored in the central terminal.
S4: when the mobile terminal is accessed to the central terminal, judging whether the mobile terminal has the control authority of the controller, and if so, executing the step S5; otherwise, not executing the operation;
when the mobile terminal is connected to the central terminal, that is, the mobile terminal wants to control the controller through signal transmission of the central terminal, the right of the mobile terminal needs to be judged, wherein the control authority of the mobile terminal is judged according to the number of the controller, and one mobile terminal may have one or more control authorities of the controller.
And when the step S4 is executed, the mobile terminal is connected to the central terminal through Bluetooth or wifi. Preferably, the connection is made by Bluetooth in a warehouse or in a factory where the signal is poor, and the signal transmission between the mobile device and the central terminal is independent of the network speed and can be carried out within a certain range
And, the administrator may give the control authority of the controller specified by the mobile terminal, or may delete the control authority of the controller specified by the mobile terminal, and then when executing step S4, it is determined in real time whether the mobile terminal has the control authority of the controller.
S5: the central end sends the key of the controller to the mobile end;
the mobile terminal with the control authority of the designated controller may accept the algorithm library and the key corresponding to the controller sent from the central terminal, and in general, the algorithm library is obtained from the central terminal when the mobile terminal first obtains the control authority of the controller, or when the mobile terminal is first connected to the central terminal with only one algorithm library, that is, before executing step S5.
Then, the central terminal sends the key of the controller to the mobile terminal with the control authority of the controller, and the mobile terminal has the algorithm library and the password of the designated controller, so that the control of the controller can be performed.
S6: acquiring real-time, acquiring a corresponding algorithm from an algorithm library through a key, and controlling and managing the controller through the algorithm.
The step S6 here is specifically: the real-time is acquired through a network, the algorithm password corresponding to the real-time is acquired in a specified algorithm library through a key, the mobile terminal acquires the real-time algorithm password, the algorithm and a control instruction are sent to a controller, and the controller responds to the control instruction to control the roller shutter door, such as ascending, descending, suspending, stopping suddenly and the like.
It should be noted that, the real-time is not only the current (Beijing) time, but may refer to a time difference value between the current time and a preset zero time, and the current algorithm password may be obtained according to the difference value and the key rule.
Of course, when executing step S6, the controller acquires the wrong algorithm instruction information twice in succession, and gives an alarm to avoid the simulation and decoding of lawless persons.
The control method of the Bluetooth broadcast rolling door for preventing decoding is good in safety, decoding can be effectively prevented, the risk that a wireless signal is intercepted and simulated to open the door can be effectively reduced, the control mode is novel, the Bluetooth broadcast rolling door can be used together with APP, and financial safety is guaranteed.
The present invention is not limited to the above-described specific embodiments, and various modifications and variations are possible. Any modification, equivalent replacement, improvement, etc. of the above embodiments according to the technical substance of the present invention should be included in the protection scope of the present invention.
