Problems solved by technology

When the traditional information access system is used in multiple local wireless sensor network systems, multiple WEB sites need to be configured, and each WEB site has an independent server and database, which not only increases the cost of software and hardware, but also increases the cost of information access for users It is not easy to remember and cause a lot of inconvenience when you need to enter different domain name addresses

Embodiment 1

[0024] An information access system for multiple wireless sensor networks such as figure 1 As shown, the system includes two parts: multiple local wireless sensor network systems and remote WEB sites for users to visit; the local wireless sensor network system includes multiple sensor information collection nodes, routing nodes, gateway nodes, and gateway nodes through the RS232 interface The connected upper computer PC; the remote WEB site includes server and database parts, using WAMP architecture.

[0025] An access method for an information access system for multiple wireless sensor networks, such as figure 2 As shown, including information collection methods and information access methods. Information collection methods are as follows:

[0026] The sensor information collection node routes the collected environmental information in the form of data stream through the router node or directly transmits it to the gateway node, and the gateway node transmits it to the uppe...

Embodiment 2

[0033] An information access system and access method for multiple wireless sensor networks, which are the same as in Embodiment 1, except that the server and the database part adopt the LAMP architecture.

Abstract

The invention relates to an information access system for a plurality of wireless sensor networks and an access method, which belong to the technical field of electronic information. The system comprises two parts, i.e. a plurality of local wireless sensor network systems, and a general server and a database for a user to have access to. Each local wireless sensor network system comprises a plurality of sensor information acquisition nodes, a router node, a gateway node and an upper computer, i.e. a personal computer (PC) which is connected with the gateway node. The invention also provides the information access method for a plurality of wireless sensor networks. A plurality of local wireless sensor networks directly save the sensor information to the general database via the Internet, and the server is connected with the database, so that the user can have access to the information of the wireless sensor networks through the general server, and the access flexibility and the convenience of the user are improved.

Description

technical field [0001] The invention relates to an information access system and access method for multiple wireless sensor networks, belonging to the technical field of electronic information. Background technique [0002] A wireless sensor network (WSN for short) is composed of sensor nodes distributed in different locations. Wireless sensor network consists of three types of nodes: information collection nodes, router nodes and sink nodes. The information collection node is responsible for collecting environmental information, and transmits the information to the router node or directly to the sink node. The router node is responsible for routing the information sent by the information collection node and passing it to the sink node through multi-hop. The aggregation node is the external interface of the wireless sensor network. It is responsible for summarizing the information of the entire wireless sensor network, providing an interface for users to query and call, an...
