Temperature detection method based on wireless sensor network

Abstract

The invention discloses a temperature detection method based on a wireless sensor network. A temperature detection system comprises a visual interface end and a plurality of wireless sensor network modules; each wireless sensor network module comprises a sink node and a plurality of end nodes. Each sink node comprises an MCU, a radio frequency chip, an Ethernet chip and a power module. Each end node comprises a single chip microcomputer, a radio frequency chip, a non-contact type infrared temperature detecting chip and a power module. The visual interface end is connected with the sink nodes through the Ethernet, and the sink nodes are in communication with the end nodes through the radio frequency chips. A synchronous method and a communication method are the time synchronous method and the communication method between the sink nodes and the end nodes, and the communication method comprises uplink communication and downlink communication. Due to the cooperative work of multiple wireless sensor network nodes which are low in power consumption and multiple in function, real-time monitoring, sensing, collecting and processing of temperature data in a network coverage area are completed.

Description

technical field [0001] The invention relates to a temperature detection method based on a wireless sensor network. Background technique [0002] High-voltage equipment in the power system often causes accidents due to high current or increase in contact resistance of key parts, resulting in excessive temperature rise. Therefore, these heat-sensitive parts need to be monitored in real time. Traditional monitoring systems generally require wiring and contact detection, and high-voltage equipment is not suitable for the application of this method. Contents of the invention [0003] Purpose of the invention: the purpose of the present invention is to provide a temperature detection system based on a wireless sensor network and a synchronization and communication method for the deficiencies in the prior art, through a large number of low-power multifunctional wireless sensor network nodes working together to complete The real-time monitoring, perception, collection and proces...
