Analysis and test device for nodes in wireless sensor network

Abstract

The invention discloses an analysis and test device for nodes in a wireless sensor network, belonging to the technical field of a wireless sensor network. The analysis and test device comprises multiple node communication modules, node power supply management and power consumption monitoring modules, on-line programming modules, processor modules, device configuration modules and node interface units. The analysis and test device also comprises graphical user interfaces and telecommunication modules which are connected with multiple nodes to be tested in a wired mode and communicate with a remote control computer in a serial-port or Ethernet mode to realize the analysis and test of the nodes in the wireless sensor network. The invention can simultaneously test and analyze multiple nodes in the wireless sensor network, and the test process does not influence the node ad hoc network and the working process; the invention can carry out on-line programming, simplified program update and program maintenance on the multiple nodes, thereby shortening the node debugging cycle; and the invention can acquire node information without depending on gateway nodes and multiple-hop transmission, thereby reducing information delay and transmission errors, and realizing accurate and fast information acquisition.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to an analysis and testing device for wireless sensor network nodes. Background technique [0002] With the progress of electronic technology, wireless communication technology and sensor technology, wireless sensor network has been paid more and more attention. In the research and development of wireless sensor networks, it generally involves the monitoring, analysis, and debugging of wireless sensor network nodes, including node status, network status monitoring, node power consumption monitoring, node programming, program update, etc. [0003] Considering the complex environment of node applications, researchers currently use simulation to test node protocols or programs. This method reduces the workload to a certain extent and is convenient to implement, but it cannot fully reflect the real environment, such as the failure of sensor nodes in actual work, insuff...
