Gateway supporting plug-and-play of ubiquitous devices and sensors and its operating method

Abstract

The invention discloses a gateway for supporting ubiquitous devices and sensors to be plugged and played and an operation method of the gateway. The gateway comprises a gateway main management module, a dispatching management module, a device exit management module and a cache management module, wherein the dispatching management module and the device exit management module are connected with the gateway main management module, and the cache management module is connected with the dispatching management module. The gateway main management module is in charge of processing and analyzing notification information when the devices are initially connected with the gateway. The cache management module is in charge of downloading device drivers and application programs from a network-based server. The dispatching management module is in charge of loading the device drivers and the application programs to an internal storage from a cache and conducting dispatching management on application programs operated in a system. The device exit management module is in charge of releasing occupied systematic resources when the devices exit. According to the gateway for supporting the ubiquitous devices and the sensors to be plugged and played and the operation method of the gateway, basic description information of the devices is obtained through the communication of the devices and the gateway, the automated loading of the device drivers and the application programs of the devices is achieved, working models of the devices are established, and the cache and dispatching are optimized. Under the situation that the gateway resources are limited, the throughput of the system is effectively increased, and the system performance is improved.

Description

technical field [0001] The invention relates to a gateway, in particular to a gateway supporting plug and play of ubiquitous devices and sensors and an operating method thereof. Background technique [0002] The heterogeneity of hardware devices under the Internet of Things is becoming more and more prominent. The products of each manufacturer have their own protocol standards and drive commands, and the data information structure is even more diverse. Aiming at the above problems, a series of standards have been proposed at home and abroad, such as DLNA specification, UPnP protocol and IGRS standard. The research results of gateway-based device management mainly include middleware-based and agent-based methods. No matter which method is used, it is necessary to match the command of the physical device and convert the data format to provide a unified interface for the upper layer application. When thousands of devices are connected, command parsing and data format conversi...
