Method and system for improving reliability of data communication between LAN devices based on IoT

Abstract

The invention discloses a method and system for improving the reliability of data communication between LAN devices based on IOT. The invention deploys a mapping service module and a dynamic agent module on the device side, and the device side maps the device-side feature library to the IOT through proxy mapping. platform. The present invention can improve the reliability of data communication between devices and terminals in a local area network environment when the server is not equipped with an algorithm machine. The loss of data in the middle makes the entire system unusable, improving system security and stability.

Description

technical field [0001] The invention belongs to the technical field of wireless local area networks, and relates to a communication method based on an IOT local area network. Background technique [0002] In the local area network environment, if the face recognition system is built, the server is not equipped with an algorithm machine, and the server-side face recognition and face feature database cannot be maintained. The only way to send photos to the device terminal is through the server. Face recognition and maintenance of the corresponding face feature library. Among them, the face photo is sent to the corresponding online device through the IOT protocol, and the server will copy the transmission data from the hard disk to the server buffer, and then the buffer will send it to the terminal device through the IOT protocol, and the terminal device will open a corresponding size buffer after receiving the data The zone accepts the data, and finally copies it to its own s...

[0002] In the local area network environment, if the face recognition system is built, the server is not equipped with an algorithm machine, and the server-side face recognition and face feature database cannot be maintained. The only way to send photos to the device terminal is through the server. Face recognition and maintenance of the corresponding face feature library

Among them, the face photo is sent to the corresponding online device through the IOT protocol, and the server will copy the transmission data from the hard disk to the server buffer, and then the buffer will send it to the terminal device through the IOT protocol, and the terminal device will open a corresponding size buffer after receiving the data The area accepts data, and finally copies it to its own storage. After two copies, the overhead is relatively large when transferring large amounts of data.

[0003] Moreover, in actual use, when sending photos to the terminal, network fluctuations or device offline often occur, resulting in incomplete face photo data on the device terminal, or abnormal device data, or even failure to send the photo, resulting in the terminal not working normally

In this case, the synchronization must be manually initiated again, otherwise, the device will be in a state of being unable to use normally, which is very inconvenient

If the amount of data is large, the overhead caused by sending the data again is very huge, resulting in waste of resources
