摘要：

温室培养液中一些重要营养元素的浓度往往被忽视并且 ZigBee 监测系统的核心节点协调器容易遭受捕获攻击。设计可信溶液监测系统各节点硬件结构、外部电压测量过程和数据清洗过程。为协调器节点配备可信模块，设计针对协调器的可信u-boot，对关键文件进行完整性检查，实现节点可信启动。实验结果表明，系统中每个节点可以自动地监测溶液浓度，并且协调器可信模块可以检测出被捕获的协调器并示警。因此该系统具有较强的功能性与安全性。

Abstract:

In the greenhouse environment,the concentration of nutrient solution was always ignored.At the same time,the core node coordinator of the ZigBee wireless monitoring system was easily compromised.A trusted solution monitoring system based on ZigBee wireless sensor network was designed and implemented.Firstly the hardware structure of sensor,router and coordinator was introduced.Then the processes of external voltage measurement and data cleaning were illustrated.For realizing the trusted boot of the coordinator,trusted u-boot to measure the integrity of some key files was designed.Experimental results show that the solution concentration data could be sent from each node to the monitoring computer and the remote terminal.At the same time,the trusted module of the coordinator can detect the captured coordinator node and warning.Therefore,the designed system has strong function and security.

Key words: monitoring system, ZigBee, wireless sensor network, trusted computing
