Embodiment Construction
[0020] Such as figure 1 As shown, this embodiment includes: several clusters of sensor nodes arranged in different positions in the airship, a relay node set in each cluster, a sink node connected to all relay nodes, and a shipboard control node connected to the sink node Module, in which: the sensor node collects the strain monitoring value and converts it into an electrical signal and outputs it to the relay node. The relay node does not participate in signal collection and only forwards the signal obtained by the sensor nodes in the cluster to the sink node. The sink node passes the serial port or The USB interface is connected with the on-board control module, and transmits the data information collected by the sensor nodes.
[0021] The sensing unit of the sensor node specifically includes: a resistance strain gauge fixed on the flexible skin and a Wheatstone bridge circuit connected thereto, an amplification circuit and an A / D conversion circuit, wherein: used to measure...

A near space airship state monitoring system based on a wireless sensor network comprises a plurality of cluster sensor nodes arranged in different positions in an airship, relay nodes arranged in the clusters correspondingly, sink nodes communicating with all the relay nodes, and an airborne control module connected with the sink nodes, wherein the sensor nodes are used for collecting the strain monitoring quantity and temperature monitoring quantity, converting the strain monitoring quantity and temperature monitoring quantity into electric signals, and then outputting the electric signals to the relay nodes; the relay nodes are not involved in signal collection and only forward the signals obtained by the sensor nodes in the clusters to the sink nodes; and the sink nodes are connected with the airborne control module and used for transmitting data information collected by the sensor nodes. The state monitoring signals are stably and accurately transmitted to the airborne control module through the wireless sensor network, extra weight is generated as little as possible, and the bearing capacity of an airship is prevented from being affected.
Description
technical field [0001] The invention relates to a technology in the field of aircraft, in particular to a state monitoring system for an airship in near space based on a wireless sensor network. Background technique [0002] In order to ensure the reliable operation of the aircraft in the air, a set of status monitoring system is usually designed on the aircraft. By arranging corresponding sensors at specific positions of the aircraft, such as strain and temperature sensors, the acquisition and processing of the above signals can be used to determine whether the aircraft is status work. For example, in order to obtain the strain measurement data of the flexible skin material, a large number of strain sensors must be installed and arranged on different parts of the skin. The more sensors are arranged on the skin material, the more complete the strain data of the skin material can be obtained, and at the same time, the greater the help for the further structural design of the...
