Embodiment Construction

[0037] In order to further explain the purpose, technical solutions and beneficial effects of the present invention, the present invention will be described in detail below in conjunction with specific implementations and with reference to the accompanying drawings and related C language program codes.

[0038] Such as figure 2 As shown, the present invention adds the GPRS wireless module SIM300MODEM on the basis of the GAINZ sensor development kit developed by the Ningbo Branch of the Chinese Academy of Sciences to describe the scheme of the present invention as an embodiment. The development kit directly provides a wireless sensor star network. Here, the star network is taken as an example. It is assumed that the network has 3 general nodes (numbered 1-3) and 1 sink node. The sensors installed on the general nodes for the temperature sensor. Each general node has its own short address, and the aggregation node communicates with each general node according to these differen...

Abstract

The invention relates to a remote data transmission system of wireless sensor network through GPRS. The remote data transmission system comprises general nodes, sink nodes and a monitoring centre server terminal, wherein a GPRS module is added to the aggregation nodes in the wireless sensor network; the GPRS module supports TCP / IP protocol and can communicate with an Internet network through a mobile station so as to send data collected by the general nodes to the remote monitoring centre server in a mode of IP packet; and a monitoring centre can transmit control instructions to the aggregation nodes through a GPRS network and the Internet network, and then an aggregation node controller controls the working condition of the general nodes. The invention solves the problem of remote data transmission, realizes real-time control to all monitoring nodes in the wireless sensor network, reduces operation cost, and has wide application prospect in far-distance and large-area monitoring systems.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a remote data transmission system of a wireless sensor network via GPRS. Background technique [0002] Due to its own characteristics, wireless sensor networks with modern significance have broad application prospects in large-area monitoring. The network is mainly composed of general nodes and sink nodes. General nodes are mainly responsible for collecting data, and they form a multi-hop, self-organizing, dynamic network system through wireless communication. The aggregation node mainly summarizes the monitoring data of the general nodes and transmits them to the server terminal of the monitoring center, and sends the instructions of the monitoring center to the general nodes. In most of the current wireless sensor network products, the convergence node communicates with the server PC through wired or short-distance wireless, and then interconnects with the Internet throu...
