Entity information network is used to describe structural relationships between entities. Taking advantage of its extension and heterogeneity, entity information network is more and more widely applied to relationship modeling. Recent years, lots of researches about entity information network modeling have been proposed, while seldom of them concentrate on equipment-standard system with properties of multi-layer, multi-dimension and multi-scale. In order to efficiently deal with some complex issues in equipment-standard system such as standard revising, standard controlling, and production designing, a heterogeneous information network model for equipment-standard system is proposed in this paper. Three types of entities and six types of relationships are considered in the proposed model. Correspondingly, several different similarity-measuring methods are used in the modeling process. The experiments show that the heterogeneous information network model established in this paper can reflect relationships between entities accurately. Meanwhile, the modeling process has a good performance on time consumption.

This paper mainly introduces FlexRay, a high speed, real-time and high reliability bus technology, and researches network topology structure and network communication protocol of FlexRay bus. Then this paper points out that the premise of analyzing FlexRay protocol is catching the bus data transmission, and designs a data acquisition and analysis system with FreeMASTER software and Tektronix TDS3012B digital phosphor oscilloscope. In order to verify the accuracy of the software FlexRay interface design, this paper also describes the analysis and verification procedure of the timing sequence of FlexRay bus. Lastly, this paper reminds of the application prospect of this system.

Nowadays utilized through the network, the majority of the software has their own particular and complex network interface transmission protocols. Which makes the validation of the interface protocols becomes significant and difficult in the interface testing of the software. In this paper, the network interface protocol is analyzed to help validate the software network interface, based on the capture, analysis, construction and the transmission of the packet. By using this method, the software network interface will be more effectively tested.

The limitation of traditional testing tools makes it difficult to test the software of embedded system--the resource insufficiency of the embedded system as well as the strict requirement of real-time all contribute to the unavailability of the normal method for software testing. This document introduced a method about testing of embedded software, which based on code coverage and variable watching by using the software of Testbed and RTInsight. By using this method, it’s effective to validate the software testing of embedded system.

This paper firstly introduces the basic information of CAN bus and the general method of CAN testing and points out that application layer protocol is hard to test. Secondly, this paper adapts the method of capturing, analyzing, constructing and sending CAN bus data packet to analyze certain oil system software interface protocol. Then, this paper proves this method can be usde to test the accuracy of the software interface and conduct the further software interface testing.At last,this paper points out the application suggest of this method.

Through analyzing the unique requirements of military command and control software and the characteristics of wireless message transmission, this paper studies a new message transmission mechanism based on wireless narrow band transmission, bring forward the proposal of improving wireless message transmission efficiency through improving the message queue transmission mechanism of the software, and verifies it in the new software version. The results show that new transmission technology greatly improves large-scale network transmission effect.

This paper is to study the common architecture of the software development and compare the software system architecture-selection criteria. Meanwhile, this paper offers appropriate software architecture solution according to the features of data information management of the software testing organization.
