Device for detecting energy consumption and faults of Zigbee wireless sensor network node

Abstract

The invention discloses a device for detecting energy consumption and faults of a Zigbee wireless sensor network node, and is used for solving the technical problems that the wireless sensor network node is not beneficial to saving the energy of a whole network and prolonging the service life of the whole network because the wireless sensor network node can not detect self energy consumption and faults. The device mainly comprises a sensor socket, a signal amplification module, a working state indication module, a high-frequency transmission module, an energy consumption and fault detection module, a cell/power supply module and a serial port output module. The detection on the energy consumption and faults of the wireless sensor network node is realized by the energy consumption and fault detection module consisting of an MSP430 singlechip through control connection of the sensor socket and the sensor network node. The device for detecting the energy consumption and faults of the Zigbee wireless sensor network node, disclosed by the invention, has the characteristics and the beneficial effects of: simultaneously detecting node energy consumption and node fault information while the wireless sensor network node detects illumination intensity or humidity and temperature and networks based on a Zigbee technology, avoiding energy waste caused by sending information to faulty nodes, and prolonging the service life of the whole network. The wireless sensor network node is additionally provided with a light emitting diode, thus the working state of the sensor node is indicated by lightening or extinguishing the light emitting diode.
