Embodiment Construction

[0039] A wireless sensor network is a wireless network composed of a group of sensor nodes connected through a wireless medium. It configures a large number of miniature intelligent sensor nodes in a special way, and collects and processes target information in the network coverage area through the cooperative work of the nodes.

[0040] The node is composed of sensing unit, data processing unit, communication unit, etc. It can complete the tasks of data collection, signal monitoring, transmission of information or execution of related operations. The base station is a special node, and has an interface with the external network, and is an intermediary connecting the wireless network where the node is located and the external network where the user is located.

[0041] Cluster Hierarchy: Considerations image 3 In the local network structure shown, each cluster has a cluster head, which collects the data of the cluster members, and sends the data to the base station or a highe...

Abstract

The invention discloses an intelligent environment monitoring system and a method based on sensor networks. The system comprises nodes, a base station and a monitoring computer, wherein the nodes form wireless connections with the nodes and the base station, the base station is connected with the monitoring computer by a bus line, the monitoring nodes are communicated with the central node, and the nodes are communicated with each other as well to realize the routing algorithm of the wireless sensor network. Meanwhile, the monitoring nodes can start an intelligent self-process mechanism under the condition of failure communication to minimize the disaster damage of abnormal situation. Compared with the traditional monitoring systems, the system has better flexibility and stability by the verification of experiment. The invention is applied to places requiring real-time monitoring to environmental parameters and corresponding alarm places such as warehouses, machinery rooms, parking lots, laboratories, banks, and the like, and can also be used for intelligent home, monitoring infants and patients, preventing fire for forests, and the like.

Description

technical field [0001] The invention relates to a monitoring system and method, in particular to an intelligent environment monitoring system and method based on a sensor network. Background technique [0002] In today's society, there are frequent accidents, such as fires, thefts, etc., which are unpredictable, which brings great inconvenience to the storage and management of valuables and some special items. Emergencies have caused a lot of losses, and the reasons and responsible persons are also Difficult to trace. In view of this situation, real-time monitoring of environmental parameters and corresponding alarms are required. The wireless environment monitoring system has great market demands and wide application prospects. [0003] The characteristics of the traditional monitoring system are as follows: [0004] 1. Most of the alarms adopt a star structure (that is, one central node and multiple monitoring nodes). The monitoring nodes only communicate with the centr...
