In this paper, an open source web service software—gSOAP which is transplanted to the embedded Linux is proposed. Web service is not only an application entity for building applications, but also a distributed applications platform which runs operations interoperably. It can also execute all kinds of operating systems (OS) which support HTTP protocol. With the rapid development of the embedded system, lots of open-source software is transplanted to the embedded platform by embedded operating systems.

Embedded Operating Systems

In automatic systems used in the control and monitoring of industrial processes, fieldbuses with specific real-time requirements are used. Often, the sensors are connected to these fieldbuses through embedded systems, which also have real-time features specific to the industrial environment in which it operates. The embedded operating systems are very important in the design and development of embedded systems. A distinct class of these operating systems is real-time operating systems (RTOSs) that can be used to develop embedded systems, which have hard and/or soft real-time requirements on small microcontrollers (MCUs). RTOSs offer the basic support for developing embedded systems with applicability in a wide range of fields such as data acquisition, internet of things, data compression, pattern recognition, diversity, similarity, symmetry, and so on. The RTOSs provide basic services for multitasking applications with deterministic behavior on MCUs. The services provided by the RTOSs are task management and inter-task synchronization and communication. The selection of the RTOS is very important in the development of the embedded system with real-time requirements and it must be based on the latency in the handling of the critical operations triggered by internal or external events, predictability/determinism in the execution of the RTOS primitives, license costs, and memory footprint. In this paper, we measured and compared the timing performance for synchronization throughout an event, semaphore, and mailbox for the following RTOSs: FreeRTOS 9.0.0, FreeRTOS 10.2.0, rt-thread, Keil RTX, uC/OS-II, and uC/OS-III. For the experimental tests, we developed test applications for two MCUs: ARM Cortex™-M4 and ARM Cortex™-M0+ based MCUs.

Wide Availability

General-Purpose Operating Systems (GPOSes) are being used more and more extensively to support interactive, real-time, and distributed applications, as found in the multimedia domain. In fact, the wide availability of supported multimedia devices and protocols, together with the wide availability of libraries and tools for handling multimedia contents, make them an almost ideal platform for the development of this kind of complex applications. However, contrarily to Real-Time Operating Systems, General-Purpose ones used to lack some important functionality needed for providing proper scheduling guarantees to application processes. Recently, the increasing use of GPOSes for multimedia applications is gradually pushing OS developers towards enriching the kernel of a GPOS so as to provide more and more real-time functionality, thus enhancing the performance and responsiveness of hosted time-sensitive applications. In this chapter, an overview is performed over the efforts done in the direction of enriching GPOSes with real-time capabilities, with a particular focus on the Linux OS. Due to its open-source nature and wide diffusion and availability, Linux is one of the most widely used OSes for such experimentations.

In the early day of environment monitoring, the measurement is generally done through manual measurement from simple and analog instrument which suffer from the drawbacks like poor accuracy, need of human intervention, associated parallax errors and durability. The rapid development in electronic technology has made reliable integration of smart electronic sensors, processor, and communication device capable of monitoring environmental parameters more favorably. A system for ambient air condition monitoring has been developed as described in this paper. It is based on the embedded system, smart electronic sensor, commercial off-the-shelf (COTS) components, and the terminal monitor by the Graphical User Interface (GUI).

The Embedded System

The demand for equipment has been unable to meet the current and future high performance application anddevelopment needs with the rapid development of electronic technology and upgrading of traditional industries inChina. At the same time, intense market competition and technical competition require that the development cycle ofthe product to be as short as possible. Obviously, the software and hardware of embedded system are becoming moreimportant foundation of technological innovation in various fi elds. The embedded system is a combination of advancedcomputer technology, semiconductor technology, electronic technology and the specific application of variousindustries. This determines that it must be a technology-intensive, capital-intensive, highly fragmented and innovativeknowledge integration system. The embedded type is based on the application of computer technology-based hardwareand software can be tailored to adapt to the application system on the function, reliability, cost, size, power and otherstrict requirements of the special computer system. The emergence of consumer appliances and cheap microprocessorsembedded systems will form larger application areas in daily life to as the embedded system usually has low powerconsumption, small size and high integration.

And Function

In the 21st century, with the rapid development of computer science and technology, the usage of all kinds of embedded system is increasingly common. The function of the embedded system is more and more strong, and there has many kinds of embedded systems, the range of application is gradually expanded. With the requirements of application, embedded system experienced the changes from single application system to integrated system. However, because the current integrated systems mostly are limited to the stand-alone usage, this does not give full play to the application and function of the embedded system. The paper was based on the limitations of XML embedded system of the J2ME platform, and it provided optimization design to current limitations, at the same time it made the application and function get the promotion.
