Use of CAN BUS for data transmission in Real-Time mode with Simulink on control objects is considered (6-DoF a platform).It is revealed that software of CAN_ API.dll adapters, created in the Microsoft Visual Studio (MVS) does not work with TDM-GCC-64 Matlab/Simulink because of different approach in names of the dll functions according to the standard C ++ 11/17. Recompile by the developer of the adapter of its software (dll) in the TDM-GCC-64 environment under Windows is required.It is established that CAN BUS considerably reduces modeling speed by 4.5 times. The way of information compression and fall forward of exchange twice due to byte-by-byte entering of two float values in the data field is offered. Use of identical values of identifiers is applied to two cylinders 6-DoF of a platform and the subsequent their division in the program microcontrollers of cylinders.For implementation of a Real-Time mode in addition to compression it is offered to transfer data with the smaller frequency (quantization) by what a modeling clock period. It was considered that 6-DoF platforms reproduce frequency band to 10–12 Hz. The program of transfer/data exchange with Simulink on stand control devices with quantization is developed. Influence of parameter of quantization for the period of modeling is investigated. It is established that the Real-Time mode of modeling is provided in the range of parameters of quantization (chc=1/350–1/1000). Frequency of exchange with 6 cylinders at the same time corresponds to 230, 150 Hz.

Real-time remote monitoring and fault diagnosis for commercial buses has important significance in reducing the occurrence of potential accidents. This paper presents a real-time remote monitoring system for the running state of commercial passenger buses. The vehicle Controller Area Network (CAN) bus is able to collect the information of key indicators being monitored, such as brake pressure, oil pressure and fault code. Then, the collected data are uploaded to the central remote monitoring platform through a General Packet Radio Service (GPRS) module for further analysis and decision-making. In this work, a classification based data acquisition method and a hybrid configuration data transmission method are proposed to improve the efficiency of data acquisition and transmission. The authors also proposed a Run-length based relative coding algorithm to compress the massive monitoring data. Experimental results shows the average data compression ratio is 32.17%, which effectively reduces the data transmission cost.

TCP and UDP communication protocols are the most widely used transport methods for carrying out XML data messages between different services. XML data security is always a big concern especially when using internet cloud. Common XML encryption techniques encrypt part of private sections of the XML file as an entire block of text and apply these techniques directly on them. Man-in-the-Middle and Cryptanalysts can generate statistical information, tap, sniff, hack, inject and abuse XML data messages. The purpose of this study is to introduce architecture of new approach of exchanging XML data files between different Services in order to minimize the risk of any alteration, data loss, data abuse, data misuse of XML critical business data information during transmission; by implementing a vertical partitioning on XML files. Another aim is to create a virtual environment within internet cloud prior to data transmission in order to utilise the communication method and rise up the transmission performance along with resources utilisation and spreads the partitioned XML file (shredded) through several paths within multi agents that form a multipath virtual network. Virtualisation in cloud network infrastructure to take advantage of its scalability, operational efficiency, and control of data flow are considered in this architecture. A customized UDP Protocol in addition to a pack of modules in RIDX adds a reliable (Lossless) and Multicast data transmission to all nodes in a virtual cloud network. A comparative study has been made to measure the performance of the Real-time Interactive Data Exchange system (RIDX) using RIDX UDP protocol against standard TCP protocol. Starting from 4 nodes up to 10 nodes in the domain, the results showed an enhanced performance using RIDX architecture over the standard TCP protocol.

Data Encoding

Due to the ever-increasing amount of data collected and the requirements for the rapid and reliable exchange of information across many interconnected communication devices, land-based communications networks are experiencing continuous progress and improvement of existing infrastructures. However, maritime communications are still characterized by slow communication speeds and limited communication capacity, despite a similar trend of increasing demand for information exchange. These limitations are particularly evident in digital data exchange, which is still limited to relatively slow and expensive narrowband satellite transmission. Furthermore, with the increasing digitalization of ships and introducing the sustainable concept of autonomous ship operation, large amounts of collected data need to be transmitted in real-time to enable remote voyage monitoring and control, putting additional pressure on the already strained means of maritime communications. In this paper, an adaptive shipboard data compression method based on differential binary encoding is proposed for real-time maritime data transmission. The proposed approach is verified on the actual data collected on board a training ship equipped with the latest data acquisition system. The obtained results show that the proposed data encoding method efficiently reduces the transmitted data size to an average of 3.4% of the original shipboard data, thus significantly reducing the required data transmission rate. Moreover, the proposed method outperforms several other tested competing methods for shipboard data encoding by up to 69.6% in terms of compression efficiency. Therefore, this study suggests that the proposed data compression approach can be a viable and efficient solution for transmitting large amounts of digital shipboard data in sustainable maritime real-time communications.

Rapid increases in the complexity of algorithms for real-time signal processing applications have made multi-processors parallel processing technology needed. This paper proposes a design of high-performance real-time bus (RTB), based on which distributed shared memory (DSM) mechanism is established to implement data exchange among multiple processors. Adopting DSM mechanism can reduce the software overhead and improve data processing performance significantly. Definition and implementation details of RTB and data transmission model are discussed. Experimental results show the stable data transmission bandwidth is achieved with performance not affected by the increasing number of processors.
