Abstract

The invention provides a real-time energy consumption monitoring system for multi-nodes of a wireless sensor network in a working environment, which uses a WiFi network as network connection of the system. The monitoring system comprises wireless sensor nodes (5), an energy consumption measuring unit (4), a wireless router (3), and a data server (2), wherein users (1) access the data server (2) of the system by internet, the data server is connected with the wireless router, and the energy consumption of the wireless sensor nodes is collected by the measuring unit and then sent to the wireless router by a WiFi interface. The system has small volume, can move, is easy to access into a wireless sensor network, and has no interference to node operation. The invention can be used for measuring energy consumption of nodes of the wireless sensor network in a working environment.

Description

technical field [0001] The invention relates to a real-time energy consumption monitoring system for multiple nodes of a wireless sensor network in the environment, in particular to a data acquisition system for real-time energy consumption detection of low-power wireless sensor network nodes. Background technique [0002] The wireless sensor network is implemented by placing multiple sensor nodes in the environment to monitor the environment. At present, the low power consumption design mainly relies on simulation as a technical means. Such estimates are unreliable and cannot reflect the impact of various factors in the actual environment on energy consumption. Impact. Therefore, at the beginning of the design, it is necessary to consider the real-time energy consumption of the monitoring nodes in the actual environment. With the development of electronic technology, micro-electro-mechanical system (MEMS) technology, and wireless communication technology, the more nodes an...
