Mobile Phone Controlled Wireless Data Acquisition System Based on Bluetooth Piconet
Bie Hong-xi · Microcomputer Information · 2009
A distributed wireless data acquisition system was implemented based on Bluetooth technology, where a mobile terminal worked as the control console to communicate with multiple data acquisition cells and receive data in real time. Based on Mobile windows OS, the bluetooth communication software solutions were discussed by employing the protocol stacks from Microsoft and Widcomm . Key issues such as network connection, security authentication, synchronous acquisition and data processing were studies in detail. The Mobile Phone controlling system can invoke the self-check of data acquisition cells and calibration of sensors. It can also control the data acquisition procedures, collecting , processing, saving the data and displaying in curved form.
