Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The first embodiment is as follows:
an embodiment of the present invention provides a network configuration-free wireless control method for a device, which is used for wireless control of a control end of a user on an intelligent device, and as shown in fig. 1, the method includes the following steps:
s1, connecting the control end into a wireless local area network, starting a hybrid mode by the intelligent equipment, and capturing wireless original data in real time;
and S2, the intelligent device captures the control data sent by the control terminal in the wireless local area network, analyzes the control data and then executes the action.
By adopting the method, the intelligent equipment can receive all data passing through the network card when in the hybrid mode, so that control data sent by the control end in the wireless local area network can be captured by the intelligent equipment, and the intelligent equipment analyzes the data and then executes operation action; therefore, the intelligent equipment does not need to be subjected to network distribution operation, a user can carry out wireless control on the intelligent equipment through a control terminal such as a mobile phone connected with a local area network, and even if the current local area network is only the local area network and does not have the capacity of connecting a wide area network, such as network arrearage, external network line fault and the like, the wireless operation on the intelligent equipment can be realized through the method and the system; application scenes and applicable users of the intelligent equipment are increased.
In this embodiment, the wlan is based on an 802.11 wireless protocol. The 802.11 wireless protocol has the advantages of high data throughput and optical network coverage.
Step S2 further includes the smart device filtering the control data to capture only the control data of the designated control end. The method for filtering the control data by the intelligent equipment comprises the following steps: address addressing filtering and synchronous byte filtering; the address addressing filtering can enable the intelligent equipment to only grab control data sent by a control end of a specified IP address, and the synchronous byte filtering enables the intelligent equipment to only grab data within a specified byte length range or specified byte content data. Therefore, the intelligent equipment can be prevented from being operated by an illegal control end, and the use safety of the intelligent equipment is improved.
Step S2 further includes encrypting the control data when the control end sends the control data. It is possible to prevent the control data from being illegally stolen or modified.
The algorithm for encrypting the control data includes at least one of: the MD5 Algorithm (Message-Digest Algorithm 5, which can convert a "byte string" of any length into a 128-bit large integer and is an irreversible string transformation Algorithm), the SHA1 Algorithm (Secure Hash Algorithm 1, which can generate a 160-bit (20-byte) Hash value called a Message Digest, which is usually in the form of 40 hexadecimal numbers), the HMAC Algorithm (Hash-based Message Authentication Code, key-dependent Hash operation Message Authentication Code), the DES Algorithm (Data Encryption Standard, which encrypts Data in 64-bit packets, and encrypts and decrypts the Data using the same Algorithm), the ECC Algorithm (Elliptic curve cryptography), the RSA Algorithm (algorithms for both Data Encryption and digital signatures), the AES Algorithm (Advanced Encryption Standard, is a symmetric encryption algorithm). The present embodiment is preferably an AES128 encryption algorithm in the AES algorithm, and the AES128 encryption algorithm is simple and is favorable for parallel computation, and has high security performance.
In step S2, the control end transmits the control data in a broadcast or multicast manner. When the data is transmitted in a broadcast mode, the data is transmitted to all receivers in the local area network without knowing the IP addresses of the receivers; when data is multicast-transmitted, the data is transmitted to a designated group of receivers, and receivers outside the group cannot receive the data.
The wireless local area network includes a local area network or a local area network connectable to an external wide area network. Therefore, even when the local area network does not have the capacity of connecting the wide area network, such as network arrearage and external network line failure, the control end can still send control data in the local area network, and wireless control of the intelligent equipment is realized.
Step S1 also includes initiating a promiscuous mode after the smart device is powered on. After power up, the smart device may be in a promiscuous mode for a long time.
Example two:
the second embodiment of the present invention provides a network configuration-free wireless control system of a device, as shown in fig. 2, including a control terminal 1, an intelligent device 2, and a wireless local area network module 3, where the control terminal 1 is connected to the wireless local area network through the wireless local area network module 3, the intelligent device 2 is in a promiscuous mode, and captures control data sent by the control terminal 1 in the wireless local area network in real time.
In this embodiment, the control end 2 includes a mobile phone and a tablet computer, a PC upper computer, a cloud end, etc. which are provided with the control APP. The wireless lan module 3 is preferably a wireless router.
In a second embodiment, by using the network-distribution-free wireless method for the device provided in the first embodiment, a user can wirelessly control the smart device through a control terminal such as a mobile phone connected to a local area network without performing network distribution operation on the smart device.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
