Novel wireless sensor network node

Abstract

The invention relates to a novel wireless sensor network node, including a processor unit, a wireless transmission unit, a sensor unit and a power supply module. The power module unit and the processor unit are electrically connected; the wireless transmission unit and the sensor unit are electrically connected; the processor unit is respectively connected with the wireless transmission unit and the sensor unit; the power supply module unit includes a rechargeable battery module and a non-rechargeable battery module; the rechargeable battery module and non-rechargeable battery module are connected through a converter; the rechargeable battery module includes a rechargeable battery, a power device, a voltage stabilization device and a monitoring circuit; the rechargeable battery is respectively connected with the power device, the voltage stabilization device and the monitoring circuit; and the non-rechargeable battery module includes a non-rechargeable battery. The invention applies the rechargeable battery module and non-rechargeable battery module in the wireless sensor network node at the same time, and the two can freely switch to avoid the problems of incapability of frequent charging of the rechargeable battery and frequent replacement of the non-rechargeable battery.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a novel wireless sensor network node. Background technique [0002] As the second largest network after the Internet, wireless sensor networks have had a profound impact on people's lives and are widely used in aerospace, precision machinery, automobile industry, household appliances, military, intelligent transportation, environmental monitoring, medical and health care, etc. multiple fields. In the research of wireless sensor networks, energy efficiency has always been a hot issue. There is still room for miniaturization of current processors and wireless transmission devices, but more sensors are required in wireless networks, and the types are also required to be diversified. Linking them will lead to increased power consumption. In the prior art, most of the power sources for the nodes in the wireless sensor network are common batteries. Because the servi...
