Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] see figure 1, the real-time monitoring method of node energy consumption involved in the present invention is powered by USB, without consuming the energy of the node itself, and has no interference to node activities. The monitoring method collects the voltage and current of the node, and then uploads to the USB hub through the USB channel, and the hub uploads to the server through the network. If the node is powered by USB, the monitoring method needs to be connected to the node through USB. If the node is powered by a battery, it only needs to be set in the node power supply interface selection switch 8.

[0026] figure 2 It is a logic circuit diagram of the monitoring method involved in the present invention, wherein the battery input interfaces 5 and 3 form interfaces to nodes powered by batteries, and the corresponding two USB interface...

Abstract

The invention relates to an energy consumption real-time monitoring method for the nodes of a wireless sensor network, which can accurately measure the energy consumption of sensor nodes in different operation states and different power supply modes in real time. The method can synchronously achieve sampling of the voltage and the current, is high in sampling frequency, processing speed and data transmission, can complete accurate measurement within the whole distribution range of the node current, and is applicable to the energy consumption of sensor nodes in a USB power supply mode and a battery supply mode. The method provided by the invention can achieve real-time monitoring of the energy consumption of the nodes, supports that data is uploaded to a server, and can accurately analyze the energy consumption of the wireless sensor network via a common wireless sensor test platform.

Description

technical field [0001] The invention relates to a real-time monitoring method for node energy consumption suitable for a wireless sensor network. The method accurately monitors the energy consumption of the nodes in real time, so as to analyze the energy efficiency of the protocols run by the nodes and predict the service life of the nodes. The invention belongs to the technical field of wireless sensor networks. Background technique [0002] A wireless sensor network (WSN) consists of autonomous sensor nodes that are spatially distributed in different locations and can communicate with each other. These nodes can monitor physical and environmental information such as temperature, sound, vibration, pressure, movement and pollution, and can transmit this information to monitoring terminals through the network. Due to the frequent deployment in the wild environment and the lack of continuous and stable power supply, the energy consumption of nodes has always been the core is...
