Design and Implementation of Wireless Sensor Network Data Collection Terminal Based on ARM9

Traditional data collection terminals mainly utilize the method of wire, but on the occasion of scattered collection points and the scene complex environment, it is very difficult to wire. Based on wireless sensor network technology, a kind of data collection terminal with ARM9 as a core processor is proposed in this paper, which replaces the traditional actual wiring with wireless sensor network and can send the collected data to control centre or upper PC in wireless multi-hop way. We establish the construction of wireless sensor network for online collection terminal, design collection terminal overall structure, and give the data collection terminal software implementation flow. This data collection terminal can be used in a variety of multi-tasking multi-point data acquisition systems and control systems of many industrial settings.
