Abstract

The invention discloses a wireless sensor system and a data collecting method used in the wireless sensor system. The wireless sensor system comprises a detection layer containing more than one detection node and a relay layer containing more than one relay node and more than one aggregation node, wherein the detection node is used for collecting sensor data and sending the data to the relay node in the relay layer; the relay node is used for sending the received sensor data to the aggregation node; the aggregation node is used for sending the received sensor data to an external gateway. According to the technical scheme, the wireless sensor system is divided into the detection layer and the relay layer, the collection of the sensor data is completed by the detection node in the detection layer, the relaying of the sensor data is completed by the relay node in the relay layer, one node only needs to complete one of the detection function or the relay function, and therefore the power consumption of each single sensor node is reduced.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a wireless sensor system and a data collection method applied in the system. Background technique [0002] With the increasing maturity of communication, sensor manufacturing, and embedded computing, large-scale wireless sensor network technology develops rapidly and is widely used in all aspects of people's lives, such as environmental monitoring, national defense, health inspection, traffic control, disaster relief, urban management, etc. . A typical wireless sensor network is composed of a large number of cheap sensor nodes, which can be quickly deployed in different environments and form a network through wireless self-organization, which will not be limited by the existing wired network infrastructure. Wireless sensor networks enable people to obtain a large amount of detailed and reliable environmental information in real time without being limited by time...
