近年来,使用Android终端进行远程控制在工业控制、核科学技术、物联网等领域有了长足的进步,但是在大气科学领域,目前应用的例子还很少。针对大气科学外场实验对于远程控制的需求,结合Android设备在远程控制方面的优势,提出了一套基于Android的大气测量设备远程控制系统。该系统基于C/S架构,在IOCP模型与TCP Socket的基础上设计了一个较为稳定高效的跨平台通信框架,最终实现了多Android设备对多大气测量设备的远程控制。 相似文献

The MANTIS MultimodAl system for NeTworks of In-situ wireless Sensors provides a new multithreaded cross-platform embedded operating system for wireless sensor networks. As sensor networks accommodate increasingly complex tasks such as compression/aggregation and signal processing, preemptive multithreading in the MANTIS sensor OS (MOS) enables micro sensor nodes to natively interleave complex tasks with time-sensitive tasks, thereby mitigating the bounded buffer producer-consumer problem. To achieve memory efficiency, MOS is implemented in a lightweight RAM footprint that fits in less than 500 bytes of memory, including kernel, scheduler, and network stack. To achieve energy efficiency, the MOS power-efficient scheduler sleeps the microcontroller after all active threads have called the MOS sleep() function, reducing current consumption to the μA range. A key MOS design feature is flexibility in the form of cross-platform support and testing across PCs, PDAs, and different micro sensor platforms. Another key MOS design feature is support for remote management of in-situ sensors via dynamic reprogramming and remote login.
