Problems solved by technology

However, for military unattended ground sensor systems, the military generally does not allow the use of commercial infrastructure communication facilities for data transmission. For military unattended ground sensor systems including camera nodes, there are long data transmissions caused by UHF wireless communication modules. The communication channel is occupied for a long time by the package time, which leads to time-consuming and target missed detection problems

Abstract

The invention discloses a wireless sensor network node which adopts a double-microprocessor system, and the double-microprocessor system is formed by connecting a first microprocessor and a second microprocessor through a serial port; the first microprocessor is connected with a UHF (Ultra High Frequency) wireless communication module and a first Bluetooth communication module, and receives and forwards a long data packet through the UHF wireless communication module and the Bluetooth communication module; the second microprocessor is connected with a VHF wireless communication module and a second Bluetooth communication module, and receives and forwards the short data packet through the VHF wireless communication module and the second Bluetooth communication module. According to the invention, long and short data packets can be transmitted wirelessly at the same time so as to ensure smooth information transmission of an unattended ground sensor system, and the problems of time consumption and target missing detection caused by blockage of a wireless transmission channel are avoided.

Description

technical field [0001] The invention relates to the technical field of wireless sensors, in particular to a wireless sensor network node. Background technique [0002] In the past 30 years, a variety of vibration sensor nodes, vibration-sound sensor nodes, vibration-magnetic sensor nodes, vibration-sound-magnetic sensor nodes, microwave radar and microwave radar-cameras have been developed successively at home and abroad. Nodes are used to detect intrusion targets such as people and vehicles. These nodes are collectively referred to as Wireless Sensor Network (WSN) nodes, also known as Unattended Ground Sensor (T-UGS) nodes. [0003] Most WSN nodes use 2G / 3G / 4G or WiFi to transmit data and images / videos, and some use UHF wireless communication modules to transmit long and short data packets. However, for military unattended ground sensor systems, the military generally does not allow the use of commercial infrastructure communication facilities for data transmission. For mi...
