GPSR and SOAP interaction-based service network in building and construction method of service network

Abstract

The present invention relates to a GPSR and SOAP interaction-based service network in a building and a construction method of the service network. The network includes an aggregation node, a registration service center and a plurality of sensor nodes distributed in the building; the aggregation node is used for distributing services provided by the sensor nodes to the registration service center, forwarding received service requests of users to sensor nodes that can provide services for the users; the registration service center is used for registering the services of the sensor nodes and acquiring the information of the sensor nodes that can provide services according to self service description information of the users which is received by the registration service; a sensor network geographic routing protocol is adopted between the aggregation node and each sensor node as a communication carrier, and the geographic position information of the sensor nodes and the aggregation node when the sensor network geographic routing protocol is adopted are determined according to a three-dimensional coordinate system which is constructed in the building in which the above nodes are located, and the addresses of the sensor nodes are determined through adopting the coordinates of the sensor nodes in the constructed three-dimensional system.

Description

technical field [0001] The invention relates to a service construction method in an intelligent building application based on a sensor network service, in particular to a service network based on GPSR and SOAP interaction in a building and a construction method thereof. Background technique [0002] Intelligent buildings are the integration of advanced technologies in various aspects such as construction, communication, computer and control, so that the equipment in the building can work in harmony and be rationally integrated into an optimal whole, thereby creating an environment with maximum efficiency and minimum consumption for users. At present, the application of sensor network technology in intelligent buildings is very common, typical examples include security systems, fire alarm systems, and elevator operation monitoring systems. However, most of these applications are aimed at a specific application scenario, and each adopts a different protocol, which inevitably r...

Problems solved by technology

The indirect method generally uses middleware technology to set up the service on the third party between the sensor node and the user; while using the intermediate link to replace the sensor to provide services, the flexibility is poor, and the service cannot be dynamically updated according to changes in the sensor network environment , configure and tune

In the direct method, the sensor node is directly used as the service provider by using the sensor to directly construct the service. Compared with the indirect method, the flexibility is improved; however, the direct method generally uses the IP-based communication protocol in the Web service when communicating. , and with the continuous development of sensor network technology, it is unrealistic to assign a unique IP address to each sensor
