Heterogeneous multimode gateway device, and transmission method and application thereof

Abstract

The invention provides a heterogeneous multimode gateway device, and a transmission method and application thereof. The heterogeneous multimode gateway device comprises a communication link, a link detection module, a link switching module and a strategy selection module, wherein the communication link is used for providing a physical channel for realizing data communication between a monitoring module and a server; the link detection module is used for detecting a link, selecting an optimal link and transmitting an optimal link signal; the link switching module is connected to the link detection module and is used for receiving the optimal link signal and carrying out link switching according to the received optimal link signal; and the strategy selection module is connected to the link detection module. The invention provides a various link modes communicating with the server to realize management and switching of a gateway link, the strategy selection module inputs corresponding judgement parameters into the link detection module, the link detection module selects the current optimal link and informs to the link switching module, and the link switching module carries out link switching according to the input optimal link, so that optimization of an unlink data link of a gateway is realized, and the stability of gateway data transmission is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a heterogeneous multi-mode gateway device and its transmission method and application. Background technique [0002] With the continuous development of the sensor network and the continuous upgrading of its application technology, the sensor network gateway plays an increasingly important role. It closely links the traditional communication network with the emerging sensor network. On the one hand, it can connect various sensors and nodes through the downlink network to realize local interconnection. On the other hand, it can establish connections with servers and the Internet. , to achieve wide-area interconnection. At the same time, the gateway can also provide protocol conversion of different network types to realize the fusion of multi-link information. [0003] The gateway of the sensor network has a wide range of uses and can be used in intelligent ...

However, it does not take into account the further operations that need to be performed if the bound link cannot meet the transmission requirements. In addition, there are solutions proposed in the literature that have specific requirements for the message format of multiple business data, such as in water conservancy security systems. , it is necessary to set the message of each sensor and bind the service link, which will reduce the versatility of the equipment and the efficiency of engineering construction
