The design of an ultra-low-power node controller of the wireless gas sensor network

为了对瓦斯浓度进行全方位、无人值守的实时监测和智能预警，降低煤矿生产安全隐患，利用Ad—Hoe无线传感器网络、无线通信技术，通过对瓦斯涌出的动态变化特性的分析，提出了一种用于煤矿瓦斯监测系统，并使用nRF903和微控制器MSP430F149设计出一种特定的瓦斯监测系统的网络节点机，给出了一种物理层通信的超低功耗能量控制的方法．测试结果证明该模块适合Ad—Hoe传感器网络层节点机的应用，具有集成度高、微型化、功耗低等特点．

To monitor the gas strength with whole orientation, real time and unmanned, using Ad - Hoc sensor network and wireless communication technology, a gas monitor system in coal mine was presented by analyzing the gas pulling up dynamic characters. A node controller was designed, which is consisting of nRF903 and MSP430F149 and so on. Some methods which are used for super energy-efficient in the physical layer were put forward. By testing it is proved that the module is adapted to Ad-hoc sensor network sink node controller. The module is high integration, subminiature and low power wasting.
