Most of existing integrated remote controllers can control only a group of home appliances made by the same manufacturer. And they cannot monitor the status of home appliances since they are based on analog RF(Radio Frequency) signal and operate in a uni-directional manner In this paper, we propose a software framework for a hi-directional universal remote controller(URC) which monitors the status of home appliances in Wireless Personal Area Network(WPAN). The URC can handle the control and status messages which consist of a command with related arguments. When a user wants to control any home appliance, the URC can be dynamically configured to its dedicated remote controller by generating a GUI according to its profile. Any other devices which have a capacity for understanding the profile from the controlled devices can play the same role of the URC.

Multiple convenience features have been getting installed in recently released cars. However, the control of them has many uncomfortable matters yet. To resolve them, it is needed to study how to use easier the convenience features and control them remotely. Currently, wide range of convergence services are being released in various industries by using smartphone and smartphones with its state-of-the-art functions also are being released. In this paper, we design and implement smartphone-based applications for controling the vehicle's convenience features to control the vehicle convenience features with smartphone. To do this, we configure CAN (Controller Area Network) communication between the vehicle's various convenience features, and establish MCU (Micro Controller Unit) to control each feature. We also connect between the MCU and smartphones to make them available for the remote control. We can control lights, turn signals, audio, windows, air conditioner, and so on with the implemented smartphone-based control service of vehicle's convenience features using CAN remotely.

One of the basic goals, when considering networks for communication in industrial control applications, is the reduction of complexity of related wiring harnesses. In addition, the networking offers the advantages for industrial control applications, such as ease of cabling, ease of changes in the cabling, ease of adding controller modules, etc. CAN (Controller Area Network) is generally applied in car networking in order to reduce the complexity of the related wiring harnesses. These traditional CAN application techniques are modified to achieve the real time communication for the industrial control applications. In this paper, we propose the method of CAN Identifier assignment for Real-Time network system. This method is can be used to scheduling messages on CAN for Real-Time network system. And also, the real-time network system is developed and the proposed moth(Ids are verified experimentally.

In this paper, several network nodes that are essential elements of create a distributed system have designed and developed using CAN(Controller Area Network). The network nodes consist of RISC(Reduced Instruction Set Computer) CPU and CAN controller. By these two parts used, the network nodes have merits that are fast process speed, stable communication, cheapness and others. The most important quality that is the designed network node can be applied to various network control systems.

Interacting Spherical tank has maximum storage capacity is broadly utilized in industries because of its high storage capacity. This two tank level system has the nonlinear characteristics due to its varying surface area of cross section of tank. The challenging tasks in industries is to manage the flow rate of liquid. This proposed work plays a major role in controlling the liquid level in avoidance of time delay and error. Several researchers studied and investigated about reducing the nonlinearity problem and their approaches do not provide better result. Different types of controllers with various techniques are implemented by the proposed system. Intelligent Adaptive Neuro Fuzzy Inference System (ANFIS) based Sliding Mode Controller (SMC) with Fractional order PID controller is a novel technique which is developed for a liquid level control in a interacting spherical tank system to avoid the external disturbances perform better result in terms of rise time, settling time and overshoot reduction. The performance of the proposed system is obtained by analyzing the simulation result obtained from the controller. The simulation results are obtained with the help of FOMCON toolbox with MATLAB 2018. Finally, the performance of the conventional controller (FOPID, PID-SMC) and proposed ANFIS based SMC-FOPID controllers are compared and analyzed the performance indices.

This paper proposes the effective monitoring method for marine engine system, which is implemented based upon Controller Area Network (CAN). As the marine engine monitoring system requires various kind of information, a lot of sensor nodes are distributed to several places. The CAN supports huge numbers of message IDs for the sensor nodes and provides a stable communication channel in a wide area such as a 12,000 TEU container ship. Since the CAN is priority-based communication system, some of hard real-time messages like alarm messages which are time-critical to the operation of the vessel cannot be communicated within the dead-time. Therefore it is desirable to distinguish the bandwidth of the CAN for static state messages and transition-state messages not to be harmful to the engine operations. Using the features of message arbitration ability of the CAN, it is proposed in this paper that the bandwidth allocation is dynamically adjusted to cope with the increment of input signal to improve the performance of monitoring system. Effectiveness and validity of the proposed scheme have been demonstrated through real experiments.

CAN(Controller Area Network)은 시스템이 간단하고 저렴하게 구현 할 수 있는 필드버스(Field bus)로써 1980년대 독일의 BOSCH사에 의해 자동차 제어용 네트워크로 개발되었고, 실시간 계측제어 능력이 우수하여 산업전반(산업 자동화, 건을 자동화, 의료 장비, 열차, 중장비 차량)에 사용되고 있다. 본 논문에서는 CAN의 단일 마스터 시스템(Single Master System)에서 마스터 노드에 문제가 발생할 때, 전체 시스템이 다운되는 현상을 악기 위해 마스터 노드를 동적으로 변화시키는 동적 마스터 시스템(Dynamic Master System)을 제안하고 기존의 시스템과 비교하여 시스템의 가용성을 알아보았다.

The Controller Area Network (CAN) is being widely used in real-time control applications such as automobiles, aircraft, and automated factories. Unfortunately, CAN, in its current form, is not able to either share out the system bandwidth among the different devices fairly or to grant an upper bound on the transmission times experienced by the nodes connected to the communication medium as it happens, for instance, in the token-based networks. In this paper, we present An Application Layer Design for Humanoid Robot in the CAN. Besides introducing the new algorithm, this paper also presents some performance figures obtained using a specially developed software simulator and experimentation for composition of CAN which uses JTAG mode of a parallel debugging., while the behavior of the new algorithm is compared with the traditional CAN systems. in order to see how effective they are.
