Повний текст джерелаOne of the problems for manufacturers and users of flight test data acquisition equipment, is to guarantee synchronization between multiple units acquiring data on the vehicle. Past solutions have involved proprietary interconnects and multiple wire installations increasing weight and complexity and reducing inter-operation of units. This problem has become particularly important given the trend towards commercial busses, especially Ethernet, as a system interconnect. The IEEE1588 standard offers a way to transmitting time accurately over Ethernet. This paper discusses the standard, how it might be implemented, and examines the issues involved in adopting this standard for flight test data acquisition. A particular implementation that results in a synchronized four-wire Ethernet based distributed data acquisition system is discussed in section 3.

The present work consists of an implementation of time distribution protocol based on PTP disclosed in the IEC 61588:2009 / IEEE 1588-2008 standard to be used in low-power wireless devices. The distribution of time is important to determine the order of occurrence of events marked in distinct counts that can then be related. And the problems of lack of synchronicity are evident in circumstances ranging from the study of historical facts up to the investigation of intruders in modern equipments connected to the internet. The work included development of a completely new software for the microcontroller MSP430F2274TM using the CC2480TMnetwork controller. The implementation of the protocol considers one of the mechanisms described by the standard and remains very close to it, not fully conformant mainly because of lack of resources on the used device, but the expected behavior was kept. The devices synchronize the time between them and sintonize their time counting, in a way to reduce, as much as possible, the adjustments of further synchronizations.
O presente trabalho consiste em uma implementação de protocolo de distribuição de tempo baseado no PTP, definido na norma IEC 61588:2009/IEEE 1588-2008 a ser utilizado em dispositivos sem fio de baixo consumo de energia. A distribuição de tempo é importante para determinar a ordem de ocorrência de eventos marcados em contagens distintas que podem então ser relacionadas. E os problemas de falta de sincronia são evidentes em circunstâncias que vão de estudo de fatos históricos até a verificação de intrusos em equipamentos modernos conectados à internet. O trabalho contou com desenvolvimento de um software completamente novo para o micro-controlador MSP430F2274TM utilizando o controlador de rede CC2480TM. A implementação do protocolo considera um dos mecanismos apresentados pela norma e ficou muito próxima, não atendendo-a plenamente principalmente por falta de recursos no dispositivo utilizado, mas manteve o comportamento previsto. Os dispositivos sincronizam os tempos entre eles e sintonizam suas contagens de tempo, de forma a reduzir, tanto quanto possível, o ajuste de futuras sincronizações.

Повний текст джерелаFörekomsten av distribuerade realtidssystem kräver protokoll för noggrann tidssynkronisering mellan enheter. Ett sådant protokoll, Precision Time Protocol (PTP), kan uppnå en precision på under mikrosekunden under synkronisering. PTP kan implementeras i både hårdvara och mjukvara. Den här rapporten fokuserar på att analysera hur systembelastning kan påverka precision och noggrannheten hos mjukvaruimplementerad PTP mellan två enheter. Testen utfördes på två stycken Intel Galileo Generation 2 kö- randes Linux. Mjukvara användes sedan för att simulera belastning på olika system såsom CPU, I/O, nätverk och på operativsystemet. Data extraherades ifrån loggar från mjukvaran, vilken sammanfattades i grafer för att sedan analyseras. Resultaten visade att precisionen och noggrannheten hos PTP försämras under vissa typer av systembelastningar, mest märkbart under tung I/O belastning. Resultaten är dock potentiellt inte applicerbara på verklighetscenarion på grund av begränsingar i hårdvaran samt att syntetiska stresstest inte motsvarar normal belastning. Ytterligare forskning krävs för att analysera hur och varför olika typer av systembelastning påverkar PTPs precision och noggrannhet.

With the progress of the times, the dependency on desktop computers by people now is gradually shifted to mobile devices. Smart phones and tablet computers more and more popular. Mobiles devices bring a new type of life to people. People can use mobile devices to communicate to other people or other smart devices, also people can interact with smart mobile devices. Aglobal standard time for mobile devices to follow bacomes a basic issue. So a high precision time synchronization method is needed. In this paper, we design and implement a clock synchronization system for mobile devices. It is based on IEEE1588 precise time protocol. The IEEE1588 protocol defines the information and rules for precision time protocol (PTP). It can measure the clock offset between two devices by the exchange of time network packets. We build a virtual clock so that the operating system of mobile devices will not be invaded. IEEE1588 precision time protocol, clock state estimator and controller are used to implement clock synchronization system. First we use IEEE1588 precision time protocol to measure the clock offset between devices. Second we use the Kalman filter to estimate the clock state. Also, the parameters of the Kalman filter are adjusted by clock noise estimators. And third we adjust the clock frequency and control the clock phase by a proportion-integral controller. Experimental results show that our system provides good clock synchronization performances for mobile devices
