Embedded system is gradually penetrated into all fields of human society, and ubiquitous embedded applications constitute the 'ubiquitous' computing era. Embedded operating system is the core of the em-bedded system, and it directly affects the performance of the whole system. Our Liaoning Provincial Key Laboratory of Embedded Technology has successfully developed five kinds of device-level embedded operating systems by more than ten years’ efforts, and these systems are Webit 5.0, Worix, μKernel, iDCX 128 and μc/os-II 128. This paper mainly analyses and compares the implementation mechanism and performance of these five kinds of device-level embedded operating systems in detail.展开更多

The SPOS is based on single kernel architecture with its multi-task real-time kernel supporting hardware platforms and resources of mainstream mobile phones. It has remarkable advantages such as highly efficient and dynamic power management, priority - based preemptive scheduling, fast startup, a variety of drivers, and excellent system stability and operability. For the development of upper layer communication protocols and application software, the SPOS provides wireless communication interfaces and the application program framework.展开更多

EOS is responsible for the entire software and hardware resource allocation, scheduling work and coordinating concurrent control activities; some more successful applied EOS products have been presently launched. With the development of lnternet technology, information appliances and the universal application of miniaturization and specialization of EOS, EOS started from a single weak situation to a higher professional direction with strong functions.展开更多

In the system, various environmental sensors in a greenhouse are used to collect the environmental data of the greenhouse in real time, and the data are exchanged through the wireless communication module and the embedded master WinCE system plat-form in the greenhouse. The host controllers in the main controller of the greenhouse communicate with each other through the TCP/IP protocol, and communicate with the real-time monitoring and management system. The remote control of the greenhouse is performed via the monitoring page. The tests of a PC and mobile phone show that the system is reliable and easy to use, and the expected goals have been achieved in all aspects.展开更多
