Abstract

The invention relates to a ZigBee wireless sensor network communication module, comprising: an antenna unit, for receiving and transmitting the wireless signal; a radio frequency power amplifying unit connected with the antenna unit, for performing the power amplifying on the wireless signal to be transmitted; a microcontroller communication unit, based on the ZigBee protocol standard, performing the receiving process on the received wireless data package through the antenna unit and the radio frequency power amplifying unit, or outputting the wireless data package to be transmitted after performing the receiving process to the radio frequency power amplifying unit; a general purpose interface unit, connected with the microcontroller communication unit, for connecting the sensor for performing the data acquisition. According to the wireless sensor network communication module of the invention, through splicing the sensor plate to the general purpose interface unit, the sensor nodes of different types are realized with stronger reusability. In addition, through setting the radio frequency power amplifying unit, the communication distance of the module is enlarged, thereby satisfying the application of the wireless sensor network in different harsh environment.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a ZigBee wireless sensor network communication module that supports the Bee-stack protocol stack and is reusable and easy to assemble. Background technique [0002] In recent years, short-distance WPAN (Wireless Personal Area Network, wireless personal area network) communication technology has been rapidly developed. After years of research, wireless sensor network technology has begun to enter the field of industrial applications from the laboratory, in consumer electronics, home and building automation, medical health monitoring, environmental monitoring, intelligent transportation, automotive electronics, industrial control, robot systems, military, etc. It is becoming more and more widely used in the field. ZigBee protocol is based on MAC (Media Access Control, medium access control layer) and PHY (Physical Layer, physical layer) that meet the IEEE 802.15.4 s...
