Data transmission method and data transmission device

Abstract

The invention provides a data transmission method and a data transmission device and is used for carrying out data transmission between a first device and a second device. First communication connection and second communication connection are established between the first device and the second device through different communication modules. The data transmission method comprises the steps of judging whether to-be-transmitted data is the data of a first type or the data of a second type when any one of the first device and the second device needs to transmit the data to the other device; transmitting the to-be-transmitted data to the other device through the first communication connection when the to-be-transmitted data is judged to be the data of the first type; and transmitting the to-be-transmitted data to the other device through the second communication connection when the to-be-transmitted data is judged to be the data of the second type. According to the technical scheme of the invention, the problem of influencing data transmission due to the fact that a data packet is large when all data is packaged together to be sent can be avoided, and moreover, the problem that the device is out of control due to the fact that important data is lost can be avoided.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular, to a data transmission method and a data transmission device. Background technique [0002] With the development of technology, more and more household appliances and other electronic devices begin to exchange data through the network. During data exchange, in addition to the exchange of equipment status and control data, there may also be transmission requirements for multimedia information such as real-time images and sounds. [0003] At present, the transmission of device status, control data and multimedia information is basically carried out through Wi-Fi. However, the wireless communication capability of Wi-Fi is poorly adaptable to fast-changing channels, and bandwidth resources are limited. In high-density cells, it is easy to interfere with each other and cause large communication delays. Therefore, using Wi-Fi for image transmission will cause problems....

Problems solved by technology

However, the wireless communication capability of Wi-Fi is poorly adaptable to fast-changing channels, and bandwidth resources are limited. In high-density cells, it is easy to interfere with each other and cause large communication delays. Therefore, using Wi-Fi for image transmission will cause problems. Stuck and lost connection

[0004] Since the data between devices is transmitted through Wi-Fi, that is, the device status, control data and multimedia information need to be packaged in Wi-Fi data packets for transmission, which not only causes large data packets, but also causes unstable connections. Sometimes it will cause data packet loss, which will cause image and sound freezes, and even cause the loss of device status and control data, causing the problem of device out of control
