Based On ZigBee And GPRS Wireless Sensor Network Design

In the background of continuous development and wide use of wireless sensor network, wireless sensor network has become the hot spots in the industry, which is of great importance.This paper achieves wireless sensor network based on ZigBee, combined with ZigBee and GPRS. Hardware transmission instruments of ZigBee is designed with the adoption of SOC of CC2530, which is produced by TI, thus it constructs a small ZigBee sensor network. GPRS being used as technology of wireless sensor network of ZigBee, it achieves remote access and monitor of gateway system of ZigBee sensor network. On the IAR software platform, original application of ZigBee sensor network and coordinator is developed, which has achieved data collection, processing and uploading. Ultimately, PC served as the monitoring terminal to achieve remote control inside vehicles. The specific research include the following parts:1. Building the hardware environment. Some circuits are achieved, such as ZigBee sensor network nodes, and coordinator gateway module and sensor module. ARM is designed to serve as gateway processing chip, which is responsible for protocol conversion. Q24 module and CC2530 coordinator is combined to design the gateway module of monitoring system.2. Nodes software is programmed. ZigBee data collection nodes application is developed, which has achieved sensor data collection, transmission; gateway module is designed and developed, which has achieved data conversion between ZigBee sensor network and GPRS.3. Terminal based on monitoring system program is completed. It achieves the testing of ZigBee network, collection and transfer to the monitoring terminal through gateway.
