Detailed Description
The invention will be further elucidated with reference to an embodiment in the drawing.
As shown in fig. 1, the method for pairing the handle key of the roller shutter door comprises the following steps:
1) after a motor controller 3 is produced, the secret key writer 1 applies a secret key to a cloud background secret key maintenance system 5 through the internet;
2) after the cloud background secret key maintenance system 5 verifies the identity of the writer, a secret key and a motor controller serial number are randomly generated and sent back to the writer;
3) the secret key writer 1 starts the two-dimensional code printer 2 to print the two-dimensional code content of the serial number of the motor controller on the motor controller 3 and also on the corresponding remote control handle 4;
4) the secret key writer 1 writes the secret key into the control chips of the motor controller 3 and the remote control handle 4;
5) the cloud background key maintenance system 5 binds the motor controller serial number and the key together and stores the motor controller serial number and the key in a database of the system, so that the cloud background can conveniently compare and search the motor controller serial number and the key later.
As shown in fig. 4, when the key is burned in the factory, the key writer 1 obtains the unique key and the motor controller serial number from the cloud background through the internet interface 12. The secret key writer 1 starts the two-dimensional code printer 2 through the interface 14 of the two-dimensional code printer 2, prints the two-dimensional code content of the 128-bit motor controller serial number on the motor controller 3 and the corresponding remote control handle 4, and writes the 128-bit secret key into the control chips of the motor controller 3 and the remote control handle 4 so as to ensure that the secret keys of each motor controller 3 are different.
When a user needs to additionally arrange the remote control handle 4, the secret key writer 1 scans the two-dimensional code of the remote control handle 4 through the two-dimensional code scanning interface 11 to obtain the serial number of the motor controller 3, and then sends the serial number to the cloud background secret key maintenance system 5 through the internet interface 12, the cloud background finds the secret key corresponding to the serial number of the motor controller 3 according to the serial number of the motor controller and sends the secret key back to the secret key writer 1, and the secret key writer 1 writes the secret key into a control chip of the remote control handle 4 to be additionally arranged, so that the remote control handle 4 has the secret key consistent with the motor controller 3. After the remote control handle 4 with the secret key is matched with the motor controller 3, the motor can be normally controlled.
Before the additionally-arranged remote control handle 4 is matched with the motor controller 3, the originally-arranged remote control handle 4 needs to be pressed down, so that the motor controller 3 enters a matching mode, namely the additionally-arranged remote control handle cannot be automatically and directly matched with the motor controller 3 after code scanning and programming, and the system safety is improved.
As shown in fig. 5, when the key writer 1 requests the key and the motor serial number at the same time, after the cloud background verifies the identity of the key writer 1, the 128-bit key and the 128-bit motor controller serial number are randomly generated, bound together, and stored in the database.
When the key writer 1 uploads the motor controller serial number to request the key, the cloud background finds the key bound with the serial number in the database according to the serial number, and then sends the key to the key writer 1.
The transmission code of the remote control stick 4 is composed of a 128-bit code in which 16 bits of a synchronization count value, 16 bits of a control command code, 32 bits of a stick serial number, and 64 bits of reserved bits.
As shown in fig. 2, the sync count value is increased by a value after each remote control transmission, which is used as a variation factor of the whole transmission code to ensure that the data transmitted each time are different. The control command code is a specific control command, such as a door opening command, a door closing command, and the like. The handle serial number is identity information of the handle, and the controller responds to the control command when recognizing that the matched handle serial number exists. The 64-bit reserved byte is a fixed piece of data that is used to pad the data bits of the encryption algorithm. Before the remote control transmitting code is transmitted, the 128-bit transmitting code is encrypted, the encryption algorithm adopts an AES128 encryption algorithm, and the encryption key is the 128-bit key burnt by the key writer 1.
As shown in fig. 3, after receiving the 128-bit data code transmitted from the remote control handle 4, the motor controller 3 first takes out the 128-bit key burned by the key writer 1 at the time of factory shipment from the storage area, the key is identical to the key of the remote control handle 4, then decrypts the received code by using the AES128 decryption algorithm, analyzes the data of the synchronous count value after decryption, and determines that the received code is an illegal received code if the synchronous count value is smaller than the synchronous count value received last time or greater than the synchronous count value received last time by 20 or more values, and does not respond to the control command. So as to ensure that the data code transmitted last time by the remote control handle 4 is invalid and prevent the wireless transceiver from copying the transmission code and illegally controlling the motor controller 3. If the synchronous counting value meets the requirement, whether the handle serial number is already paired in the motor controller 3 is analyzed, if so, the control command is responded, otherwise, the control command is not responded.
When the rolling door is installed and debugged, a pairing button on the motor controller 3 is pressed, the motor controller 3 enters a learning state, a transmitting key of the remote control handle 4 is pressed at the moment, and the controller receives data in real time, analyzes the serial number of the remote control handle 4 and stores the serial number in a chip.
As shown in fig. 6, the roller door handle key pairing system includes:
the key writer 1 is used for acquiring a key and a motor controller serial number and writing the key on chips of the motor controller 3 and the remote control handle 4;
the two-dimensional code printer 2 is used for printing the two-dimensional code of the serial number of the motor controller on the motor controller 3 and a remote control handle 4 corresponding to the motor controller 3;
and the cloud background key maintenance system 5 is used for generating and storing the motor controller serial number and the key.
The key writer 1 includes an interface 14 of the two-dimensional code printer 2 and a key writing interface 13. After receiving the motor controller serial number, the key writer 1 controls the two-dimensional code printer 2 to print. The key writer 1 includes a two-dimensional code scanning interface 11 and an internet interface 12.
The motor controller 3 is provided with a pairing button. During installation and debugging, after the pairing button is pressed down, the controller can enter the state of the learning remote control handle 4, at the moment, the transmitting key of the remote control handle 4 is pressed down, and the controller receives data in real time, analyzes the serial number of the remote control handle 4 and stores the serial number in the chip.
The above description is only for explaining the present invention and making the present invention complete, but not limiting the present invention, and the skilled in the art can make modifications without inventive contribution to the present embodiment as required after reading the present specification, and these are all modifications without inventive contribution, but are protected by patent laws within the scope of the claims of the present invention.
