The demand for real - time operating system ( rtos ) by omnipresent embedded computing is becoming more and more urgent . the real - time supporting research of linux kernel has offered the new possibility to 無(wú)所不在的嵌入式計(jì)算對(duì)實(shí)時(shí)多任務(wù)操作系統(tǒng)( rtos )的需求日益迫切, linux內(nèi)核的實(shí)時(shí)支持研究為迎合這種需求提供了新的可能性。
In the aspect of software , the sm - te system uses c / os - real - time operating system ( rtos ) that simplifies the design of software modules and improves the stability of the system 在軟件設(shè)計(jì)方面,系統(tǒng)對(duì)各個(gè)功能模塊作了詳細(xì)的規(guī)劃并使用了c / os -嵌入式實(shí)時(shí)操作系統(tǒng),從而簡(jiǎn)化了應(yīng)用程序的設(shè)計(jì),提高了終端系統(tǒng)工作的穩(wěn)定性。
The emergence of system - on - chip ( soc ) makes the system more and more complex , and there is a growing consensus on the real - time operating system ( rtos ) because it can make the system more usable and reliable and the system design more reusable 系統(tǒng)集成芯片的出現(xiàn),使得系統(tǒng)越來(lái)越復(fù)雜, soc中的實(shí)時(shí)操作系統(tǒng)由于能提高系統(tǒng)設(shè)計(jì)的可重用性、增加系統(tǒng)的可靠性和可用性,而日益受到重視。
With the development of real - time computing , an increasing number of safety - critical applications use real - time operating system ( rtos ) as the kernel of control systems , and rtos becomes an important factor that affects the reliability of those applications 隨著實(shí)時(shí)計(jì)算技術(shù)的飛速發(fā)展,實(shí)時(shí)系統(tǒng)已成為安全關(guān)鍵應(yīng)用的核心控制部件和影響性能的決定性因素。隨著軟件功能和性能的大幅度提高,實(shí)時(shí)軟件的可靠性成為限制系統(tǒng)可靠性的瓶頸。
The remote measuring and controlling terminal based on embedded real - time operating system ( rtos ) discussed in this paper is a field control terminal system with the background of the railroad supply water system , and according to the embedded system design principle 基于嵌入式實(shí)時(shí)內(nèi)核的遠(yuǎn)程測(cè)控終端是以鐵路供水系統(tǒng)為背景的、根據(jù)嵌入式系統(tǒng)設(shè)計(jì)原理構(gòu)建的現(xiàn)場(chǎng)控制系統(tǒng)。本文提出了遠(yuǎn)程測(cè)控終端設(shè)計(jì)方案,對(duì)遠(yuǎn)程測(cè)控終端各部分的功能做了描述。
