Description

technical field [0001] The invention relates to a wireless sensor node, in particular to a wireless sensor node with automatic patrol function. Background technique [0002] At present, data collection is mainly carried out on-site through the data collection system, and then the collected data is manually transmitted to the data processing server for processing through wired or wireless means. This data collection method has poor real-time performance, that is, it cannot be collected or transmitted in real time. , so it cannot meet the actual needs. With the development of information technology such as communication and network, the development and construction based on wireless sensor network makes real-time data collection and real-time transmission possible. However, the construction of sensor networks has not yet entered the practical stage. The reason is that the functions of sensor network nodes cannot meet the requirements, such as limited energy, limited communica...

AI Technical Summary

Problems solved by technology

However, the construction of sensor networks has not yet entered the practical stage. The reason is that the functions of sensor network nodes cannot meet the requirements, such as limited energy, limited communication capabilities, limited computing and storage capabilities, etc. Among these problems, data Acquisition and processing capabilities have become the bottleneck restricting the development of standardized and ubiquitous sensor network nodes

In terms of data collection, ordinary sensor network nodes can only collect a single data, or can only connect to one analog sensor

In terms of data processing, the sampling and analysis speed of ordinary sensor network nodes is slow, the anti-interference ability in complex environments is not high, and information misinformation is prone to occur

In addition, most of the existing wireless sensor nodes do not have the function of automatic inspection, so there are practical defects such as manual inspection is time-consuming and laborious, inconvenient to use, and prone to inspection errors.

It is precisely because of the above reasons that the current sensor network nodes cannot effectively complete the real-time information collection task.
