Low power consumption node design method for wireless sensor network

Abstract

The invention discloses a low power consumption node design method for a wireless sensor network. The low power consumption node design method can monitor the temperature and humidity values of an area in real time. The system is mainly composed of a processor module, a wireless communication module, a sensor module, an energy supply module and an I / O port module. The sensor module collects and monitors the temperature and humidity values in the area, and the temperature and humidity values are processed by the processor module and are sent to a user through the wireless communication module. According to the low power consumption node design method, based on an FPGA platform, an SoPC technology is adopted for designing the maximum Nios|| system, a self-designed IP core is added, the procedures such as the interface driving procedure, the data collecting procedure, the radio frequency communication procedure and the data receiving and sending procedure are included, a node can be in a sleep state most of the time, and therefore interference is effectively reduced, and the node performance is improved. In the aspect of networking, based on the ZigBee protocol, the small wireless sensor network is constructed, upper computer software is designed, and therefore collecting, monitoring and analyzing of node data are achieved. The node is low in power consumption and cost and high in expandability and computing capability, and the requirement for applying the wireless sensor network to various fields can be met.

Description

technical field [0001] The invention relates to a low power consumption node design method of a wireless sensor network. Background technique [0002] At present, most applications in China use the development kits provided by Microchip or Freescale as the platform to conduct research on functions such as positioning and networking. This research focuses on the development of upper-layer application algorithms. A few have their own hardware platforms, which refer to the typical circuits of solutions provided by companies in the industry, and their software is still developed and implemented on the basis of the underlying protocol API interface provided by Microchip or Freescale. The basic structure of 8-bit or 16-bit high-performance single-chip microcomputer and radio frequency transceiver is generally used in the design of wireless sensor network nodes at home and abroad. The nodes can complete basic tasks such as data collection, transmission, reception and processing, bu...

Problems solved by technology

The basic architecture of 8-bit or 16-bit high-performance single-chip microcomputer and radio frequency transceiver is generally used in the design of wireless sensor network nodes at home and abroad. The nodes can complete basic tasks such as data collection, transmission, reception and processing, but the data processing ability is weak and the rate is low. Poor flexibility, not enough to meet the requirements of widely used wireless sensor networks in various fields
