Example Embodiment

[0031] Such as figure 1 As shown, the wireless sensor network monitoring system in an emergency environment consists of a monitoring center (also called a host computer), a supporting server, and a wireless sensor network.

[0032] (1) The wireless sensor network part is composed of one or more sink nodes (gateway nodes), a large number of sensor nodes and a small number of mobile nodes. Sensor nodes are distributed in the monitoring area and are responsible for collecting and uploading environmental information within their sensing radius. Generally, each sensor node can be configured with multiple sensors at the same time. In addition, ordinary sensor nodes do not have the ability to move autonomously, and will die with the exhaustion of energy; mobile nodes can move autonomously in the monitoring area while communicating with ordinary sensor nodes; sink nodes serve as wireless sensor networks and monitoring centers The coordinator of, realizes the function of uploading and iss...

Abstract

The invention discloses a wireless sensor network system under an emergency environment, which comprises a monitoring center (also called as an upper computer) and an assorted server as well as a wireless sensor network, wherein the structure of the network is designed as a whole, the model selection requirements on each mode at the node are provided, a proper MAC (Media Access Control) protocol and a routing protocol are selected and designed, and an access mechanism of a mobile node and an interest effective communication path decision rule in a routing process are provided, so that a wireless sensor network monitoring system is quickly deployed in a disaster occurrence region to monitor all kinds of environmental indexes in real time and grasp the trend of the disaster, and thus the efficiency and the quality for emergency rescue are effectively improved.

Description

technical field [0001] The invention relates to the field of wireless sensor environment monitoring, in particular to a wireless sensor network monitoring system in an emergency environment. Background technique [0002] Installing sensors in some disaster environments can achieve effective monitoring and disposal, but when a disaster occurs, the traditional monitoring system cannot meet the requirements of emergency rescue, mainly in two aspects: First, when a disaster occurs, the traditional monitoring system is extremely easy It loses its effectiveness because the line is damaged; secondly, the distribution of detectors in the traditional monitoring system is limited, and it is impossible to systematically and comprehensively cover the disaster environment, which directly leads to poor monitoring reliability and prone to false alarms. Therefore, when a disaster occurs, how to quickly and reasonably build an effective monitoring and communication network in the disaster en...
