In this paper, the design realizes a set of monitoring system based on raspberry Pi2 for the environment of industrial production logistics in tobacco business companies, which could acquire industrial wireless network signal data real-time and sound a note of alarm through positioning of various abnormal behaviors. The system adopts a monitoring method of polling frequency spot by scanning a single WLAN card, which could work continuously 7 * 24 hours daily and support the acquisition and analysis of more than 1 billion wireless data communication packet. The system uses memory database to achieve a fast, local matching analysis and warning in time. After the launching, the system run stable, and gave alarms as soon as possible in wireless network environment of the production logistics in all kinds of abnormal lfuctuations, such as abnormal lfow, channel interference, response delay of production system, various types of wireless module errors of equipment and short heartbeat signal disappears.
