Exchange Of Information

Existing ship electronic equipment are based on serial interfaces in accordance with NEMA0183 Protocol for the exchange of information, complex low transfer rates, lines, nodes exist, poor reliability shortcomings. Fieldbus (CAN) to its high anti-interference ability and higher traffic rates made up for these shortcomings, has been widely applied to automotive electronics, but in application of ship data communication has not been very good. CAN bus technology with outstanding reliability, timeliness and flexibility for the development of modern marine communication system offers a new way.

Unique Stability

Considering the bad electromagnetic environment of electric vehicle, a stable communication system is necessary. Because of its unique stability, CAN bus has been widely used in the field of automotive electronics. CANopen is a higher layer protocol of CAN bus, it has the advantages of conciseness and open-source. In this passage, based on sub-protocol DS301 and DS402, the implement of CANopen in motion control is introduced. The establishment of object dictionary and motor application object is the main content in this article.

System Programming

The tidal current energy generation system, which works underwater and is interfered by electrical transmission during the process of data communication, has field update requirements but cannot directly use In-System Programming (ISP) to update, so a remote multi-processor updating system is developed based on ISP and CAN bus. This system consists of a shore station host computer, master controller and the slaves. The host computer transmits the HEX file to the master controller via CAN bus, and the master controller updates the appointed slave by ISP. This paper studies retransmission mechanism and ISP process. The system avoids failed update caused by data channel interference through separating the HEX file transmission and the ISP process.

Electronic Circuit Design

This work deals with the passive control-based chaos synchronization with circuit design for secure communication. First, the numerical simulation and electronic circuit design of a simple five-term chaotic system are performed. The numerical simulation and electronic circuit design outputs have confirmed each other. Then, the passive control method is applied for synchronizing two identical five-term chaotic systems using only one state control signal. After the synchronization study, design and analysis for secure communication by chaotic masking method are conducted in Matlab–Simulink platform. Finally, an electronic circuit design is performed for the designed communication system. In the designed communication system with Matlab–Simulink platform and electronic circuit design, information signal which is sent from the transmitter unit is successfully retrieved at the receiver unit. As a result, the electronic circuit design has shown that a single state passivity-based synchronization signal can be effectively used for secure data communication applications for the real environment.

The Voice

Queuing theory and Markov chain analysis plays vital role in analyzing real-life problems. It is applied to wired network, wireless network and mobile communication to analyze the packet traffic in packet switched network. In this simulation and analysis, integrated communication system such as voice and data is simulated with different queue size for voice calls with different arrival and service rate and its results are analyzed to study the impact of buffering of voice and data calls for the proposed integrated wired network using Queuing theory and Markov chain analysis. We also propose to optimize the system characteristics in an attempt to provide better Quality of Service (QoS) for systems with integrated voice and data calls. The proposed models have two traffic flow namely voice calls (real-time traffic like audio) and data calls (data traffic like FTP). A single channel is assigned for voice and data calls. The incoming voice and data calls are queued when the channel is busy. Voice calls are delay-sensitive therefore priority is assigned to Constant Bit Rate (CBR) traffic voice request. For such systems, it is important to analyze the impact of buffering the voice calls as well as data calls for various mean arrival rates and mean service times for voice and data call requests. The impact of buffering the voice calls with different queue size, mean arrival rates and service rate are analyzed. These results of dedicated integrated voice and data communication system can be used for simulating any type of wired network. The minimum buffer or jitter required for both the traffic is calculated using Packet Delivery Fraction (PDF).

We study the anti-interference performance of the 802.11 system when it works as Data Communication System (DCS) in Communication Based Train Control (CBTC). We first conduct extensive experiments on a 802.11b network to assess the ability on a lab test bed, then the outdoor experiments are also conducted. In the presence of jammer, we find that in each case of interference model, there exists a C/I threshold which determine the DCS-Access Point (DCS-AP) and DCS-Station Adapter (DCS-STA) communication performance. In the outdoor environment, different interference sources are adopted to investigate the data throughput value and other parameters of the DCS system under the critical state.
