太原理 L大学硕士研究生学位论文 THE APPLIED RESEARCH OF ZIGBEE WIRELESS SENSOR NETWORK 卧 THEAUTOMATIC SYSTEM OF HYDROLOGICAL DATA ACQUISITION ABSTRACT China is a developing count巧r with the uneven distribution ofwater resources and natural disasters especially f100ds often strike it.Therefore，how to forecast and prevent floods is important for the Ministry of Water Resources in China. Ministers often forecast hydrological data and make a decision mainly based on hydrological infonnation ，which makes it become significant to forecast hydrological information timely and accurately. With the rapid development of science and technology，the traditional hydrological infonnatìon col1ection technoJogy cannot satisfy the need of the water management today However ，the automatic system ofhydroJogical data acquisitíon can realize the automatic acquisition and processing of hydroJogical data. The system is made ofwireless sensor network technology ，RTU technology ，computer network technology，database technology. IIIThe wireless sensor network technology is the basis of the whoJe system， responsible for the collecting，aggregation and forecast of hydrological data such as rainfall，water level，temperature and so on. For the traditional one has some shortcomings such as less observation points，slow data acquisition and I I I 太原理工大学硕+研究生学位论文 unreliable data transmission and so on. Fortunately ，the wireless sensor network can solve the problem effectively. Therefore，the reseracher designs a wireless sensor network model based on ZigBee technology. In the network based on ZigBee techonology，CC2430 rf Chip from TI company is adopted as the core component and the hardware circuits are designed ，inculding Coordinator Node and Sensor Node. Each node circuit uses the modular design so as to reduce complexity and increase generality between devices and stability. For the software design，the IAR EW integrated development environment and Z - Stack protocol Stack from TI company are adopted. Moreover
