针对现行节能灯管真空度，通过控制真空泵工作时间存在不精确、效果差的问题，设计一种基于CC1110的低功耗无线气压采集系统。给出系统结果原理，研究工作/休眠机制、邻居节点免冲突机制以及基于DMA的高效数据传输策略，以实例分析并计算节点能耗。实验结果表明：该采集系统功耗极低，且运行稳定可靠，多个采集节点之间没有冲突干扰，可为精确控制灯管真空度提供参考。

Aiming at energy-saving lamp vacuum degree, and the low accuracy and bad effect of current control vacuum pump working time control, design a low power wireless air pressure collection system based on CC1110. Give system result principle, research work/sleep mechanism, neighbor node collision avoidance mechanism and DMA high efficiency data transmission strategy based on DMA. Use example to analyze and calculate node power consumption. The test results show that the system power consumption is low, and system operation is stable and reliable. There is no conflict and interference among multi collection nodes, and give reference for accurate control of lamp vacuum degree.
