Application Research Of Wireless Transmission System Of Mobile Communication Network In The Monitoring Of Cyanobacteria

In the wake of21st century, Wireless sensor and communication technology tends to mature gradually, and they are widely applied in various fields. The wireless data transmission system combines wireless sensor with communication technology, applied to data monitoring on the growth environment of Blue-green Algae. It is very important to use sensor technology for data acquisition, and getting data transmission through wireless way. They relates to the data monitoring by artificial on-site exploration and cable transmission mode has improved the efficiency of the system and the scope of application,.After each node collects information by ZigBee wireless sensor network in Wireless monitoring system, then the information transmit to the gateway node through ZigBee network.After data information collection, simple treatment which from each node by each gateway node.then the information connects to the wireless network by GPRS wireless transmission module, and the gateway node transmits data information to database storage in data monitoring center. Users checks relevant data information in database through a visual interface. The research is part of issue in this paper, including data transmission and management in whole monitoring system. First system sets up hardware platform of gateway node for data transfer and transplant of operating system. Research of hardware of gateway node based on S3C2440, the hardware circuit mainly includes:S3C2440,ZigBee wireless transmission module, GPRS wireless transmission module, extended memory circuit, power supply module, CLKRST Clock Reset circuit, JTAG interface circuit, RS232serial interface circuit, etc. Transplant embedded Linux operating system at hardware platform before layout completed. The system provides reliable system platform for program.. Secondly, contrast with wireless data transmission way in GPRS network,The system eventually adopts the way of data transmission by combination of GPRS network and Internet network. Emphasis analyses IP, TCP, UDP data transfer under three kinds of transport protocol in GPRS network. In the laboratory, it completes the GPRS wireless data transmission easily. Finally,system completes the design of data monitoring center by using c#language in Visual Studio2008platform, and it connects with database by develop Visual data query interface to realize check and manage database information.This system achieves remote data transmission by wireless sensor technology and the network. System applied to data monitoring on the growth environment of Blue-green Algae, and it is able to meet the requirements of long distance, big volume, high stability in full complete satisfaction. Besides, the system can fully transplant other data monitoring system which apply to itself.
