Wireless sensor node with functions of automatic program updating and parameter correcting

Abstract

The invention discloses a wireless sensor node with functions of automatic program updating and parameter correcting, which comprises a sensor module, a CPU (central processing unit) module, a short-distance wireless communication module, a data memory module, a wireless transceiver, a program loading and updating module, a parameter correcting module, an automatic information type identification module, an information transferring module and a power module. The short-distance wireless communication module is used for automatically searching adjacent wireless sensor nodes. The wireless transceiver is used for synchronously receiving control information consisting of parameter correction information and program updating information transmitted by an upper computer while uploading data acquired by the sensor module. The automatic information type identification module is used for automatically identifying and classifying control information types. The information transferring module is used for transferring the information classified by the automatic information type identification module to the program loading and updating module and the parameter correcting module respectively. The wireless sensor node is reasonable in design, convenient in networking and maintenance, convenient and effective in use, high in intelligent level and capable of automatically upgrading and updating internal programs and correcting operation parameters.

Description

technical field [0001] The invention relates to a wireless sensor node, in particular to a wireless sensor node with functions of automatic program update and parameter correction. 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...
