Problems solved by technology

[0003] However, environmental changes and the appearance of obstacles are likely to cause instantaneous or permanent loss of connection between nodes.
At the same time, wireless sensor networks usually do not have a stable energy supply, and can only rely on their own batteries or solar rechargeable batteries as energy sources.
If the energy of the network node is exhausted or there is a software and hardware failure, the management terminal cannot display the sensor detection results normally, which will cause the management terminal to have no way of knowing the real reason why the network node cannot display normally, and will also cause other problems in the wireless sensor network. The node will continue to send information to the failed network node (referred to as the failed node) without knowing that the network node has failed to work normally.

Abstract

The invention discloses a diagnostic device and method for a failure node and a portable terminal. In one embodiment, the diagnostic method comprises the following steps: monitoring sending and receiving groups of suspected failure nodes and surrounding nodes thereof within a period of time; resolving the monitored groups to obtain the types, sources and signal intensities of the groups; determining the states of the suspected failure nodes according to the obtained types, sources and signal intensities of the groups; and displaying the states of the determined suspected failure nodes. Thus, causes of node failures can be diagnosed without changing an original network or setting limits for hardware and software of internal nodes of the network.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a faulty node diagnosis device, method and portable terminal. Background technique [0002] The wireless sensor network can monitor, perceive and collect all kinds of information of the sensing objects that the observers are interested in in the node deployment area in real time, and process the information and send it wirelessly, and finally send it to the observer through the wireless network. [0003] However, environmental changes and the appearance of obstacles are likely to cause instantaneous or permanent loss of connection between nodes. At the same time, wireless sensor networks usually do not have a stable energy supply, and can only rely on their own batteries or solar rechargeable batteries as energy sources. If the energy of the network node is exhausted or there is a software and hardware failure, the management terminal cannot display the sensor det...
