Detailed Description
The invention aims to provide a remote WiFi network configuration method for a cellular Internet of things device based on a short message service, which can efficiently and rapidly realize the remote WiFi network configuration of the device under the conditions of better universality and no generation of extra hardware cost. The method and the device are used for supporting the WiFi distribution network of the cellular Internet of things equipment with the short message service, when the equipment is started, whether WiFi distribution network information exists or not is detected, if so, wiFi hot spots are directly connected, and WiFi distribution network short messages are ignored. If the equipment does not store the WiFi distribution network information, after receiving the WiFi distribution network short message, analyzing the SSID and the password in the short message, completing the WiFi distribution network, and storing the WiFi distribution network information.
For a better understanding of the present invention, the technical terms that may be involved in the present invention are explained first below:
the internet of things (IoT) is an information carrier such as the internet and a traditional telecommunication network, so that all common objects capable of performing independent functions can realize interconnection and intercommunication.
WiFi, also known as "Mobile hotspot" in Chinese, is a brand authentication of Wi-Fi alliance manufacturers as a product, and is a wireless local area network technology created in the IEEE802.11 standard.
The short message service SMS (ShortMessagingService) is the earliest short message service, and is also the most popular short message service, through which mobile phones can send and receive short messages to and from each other, and the content is mainly text, digital or binary non-text data, and the length of the short message is limited to 140 bytes.
Examples:
as shown in fig. 1, the method for remote WiFi network configuration of a cellular internet of things device based on short message service in this embodiment includes the following implementation procedures:
s1, after the Internet of things equipment is started, attempting to read WiFi configuration network information stored in FLASH, if the WiFi configuration network information is successfully read, entering a step S2, otherwise, entering a step S3;
in this step, the WiFi configuration network information mainly includes SSID and password information for connecting to a specified hotspot, after the internet of things device is started, the information is first tried to be read from the FLASH, if the reading is successful, the specified hotspot can be directly connected according to the information, and if the reading is failed, the configuration network information in the configuration network short message needs to be obtained through monitoring the configuration network short message.
S2, the Internet of things equipment is connected with corresponding hotspots according to the read WiFi distribution network information;
in the step, if the equipment of the internet of things reads the WiFi configuration network information, the appointed hot spot can be directly connected according to the information, the equipment enters a normal running state after the connection is successful, and the equipment can communicate with the cloud end through WiFi later; if the connection to the designated hotspot still cannot be performed within a certain period of time (for example, 30 seconds) or a certain number of times (for example, 5 times), it is indicated that the read WiFi network information is invalid due to the fact that the internet of things device is currently moved out of the original designated hotspot range, or the original designated hotspot network device (router) is turned off or the SSID/password is modified, and then step S3 is needed to be performed to acquire new network information again.
S3, the Internet of things equipment starts a short message analysis module to monitor whether a WiFi distribution network short message is received, and if so, the WiFi distribution network information is analyzed from the WiFi distribution network short message;
in this step, the internet of things device starts a short message analysis module to monitor all the short messages, the user only needs to edit the telephone number (the telephone number corresponding to the SIM card inserted by the device supporting the short message service) of the internet of things device by using the mobile phone terminal to send the short message of the distribution network to the internet of things device, the short message analysis module of the internet of things device judges whether the short message is the short message of the distribution network by judging whether the monitored characteristics of the short message conform to the characteristics (such as a specific prefix or suffix) of the WiFi short message of the distribution network, and if the short message is the short message of the distribution network, the SSID and the password information in the short message are analyzed to be used as the current information of the distribution network. In addition, in order to improve the security of the distribution network information, the distribution network short message can be encrypted, so that the internet of things equipment needs to perform corresponding decryption and then analysis after receiving the distribution network short message. The encryption and decryption means can adopt common symmetric encryption and decryption, such as an AES algorithm and the like.
S4, the Internet of things equipment is connected with the corresponding hot spot according to the WiFi distribution network information analyzed from the WiFi distribution network short message;
in the step, after the WiFi distribution network information is analyzed from the WiFi distribution network short message, the Internet of things equipment can be connected with a designated hot spot according to the analyzed WiFi distribution network information, the equipment enters a normal operation state after being connected successfully, the equipment can communicate with a cloud end through WiFi later, the analyzed WiFi distribution network information is stored in a FLASH, and the information can be directly read from the FLASH after being started next time; if the connection is unsuccessful within a certain time or more than a certain number of times, returning to the step S3 again.
Finally, it should be noted that the above examples are only preferred embodiments and are not intended to limit the invention. It should be noted that modifications, equivalents, improvements and others may be made by those skilled in the art without departing from the spirit of the invention and the scope of the claims, and are intended to be included within the scope of the invention.
