This work describes a new methodology for the purpose of remote testing, debugging and maintenance of networked electronic and mechatronic systems which makes use of the IEEE 1588 high-precision clock synchronization protocol. After the underlying concepts of IEEE 1588 are briefly sketched, the paper describes how functionalities like testing, debugging and maintenance can benefit from a network-wide notion of time as provided by the IEEE 1588 standard. An implementation of the IEEE 1588 protocol with support for test, debug and maintenance as well as links to the integration of the proposed concept into existing tools are presented. Further, the proposed approach is discussed under consideration of recent standardization efforts. Finally, a case study from the area of automotive electronics is described.

In view of PTP high precise timing requirement for many application fields, GPS time service is provided with the advantages of high precision and high stabilization. The principle and timescale of PTP based on GPS are analyzed and discussed. And then a PTP time synchronization platform with GPS-based UTC time is designed and implemented, the correlative key design flowchart is described as well. Finally, the paper gives the experiment results, which show the time synchronization accuracies can reach nanosecond range.

Development of intelligent grid have increasing demands for time synchronization, high precision, large scale, high performance time synchronization system has become necessary guarantee for the normal operation of the power grid. This article introduced the composition of the time synchronization system, discusses the IEEE1588 implementation of high precision clock synchronization principle and SDH data transmission principle, analysis of the PTP protocol for transmission through the principle of the SDH E1 line, gives the networking scheme of PTP over the E1 way, which meet the precision requirement of 1 us.
