Set Up

A model of wireless network data interchange was built to solve cross-platform exchange data in intelligent robot. In the framework of embedded Soft-PLC - Codesys real-time operating system, we apply Socket network programming technology based on TCP/IP communication protocol to set up a physical channel between VC++ platform and the Codesys platform. It realizes the real-time data exchange between host-computer and slave-computer uploaded embedded operation system of robot. A special multi-threaded processing class was developed to enhance the multi-tasking allocation ability of the system. Exchanged data was packaged and analyzed to ensure the accuracy of transmitted data. The experiment shows built communication system platform is justifiable, and data transmission speed is less than 10ms. It is able to meet the needs of real-time control in intelligent robot.

<p>In this paper the Controller Area Network (CAN) Controller is presented. CAN is an advance serial bus communication protocol that efficiently supports distributed, broadcast real-time control and fault tolerance features for automobile industries to provide congestion free networking. The CAN Controller is designed for scheduling of messages, consist of the Transmitter Controller, FIFO buffer, CRC generator and bit stuffer. Scheduling messages on CAN corresponds to assigning identifiers (IDs) to message according to their priorities. Non Return to Zero (NRZ) coding and Non Destructive Bitwise Arbitration (NDBA) is used. The data is taken from the buffer FIFO, bit stuffed and then transmitted after CRC is performed. The whole design is captured entirely in VHDL language using bottom up design and verification methodology. The proposed controller was designed for applications needing high level data integrity and data rates upto 1Mbps. The applications of CAN are factory automation, machine control, automobile, avionics and aerospace, building automation.</p>

Intelligent Ground Vehicle needs real-time communication system and a better architecture to handle a variety of sensors. This paper presents a fast communication and efficient architecture for intelligent vehicle (FCEA-IV). The vehicle contains three control centers, communicating with each other based on real-time control system. And also it has a hybrid mode. In auto driving mode, it will go under the better path, calculated by considering comprehensive environmental factors. While in active control mode, the vehicle will be controlled by remote commands. First of all, we will discuss RCS (real-time control system) and why we choose it. Then the overview of system, including architecture and control structure will be discussed. Further some communication message and work flow will be studied in detail. At last we share some experiments to test the efficiency of the communication system.

The Internet of Things (IoT) is an information carrier based on network communication, and it can make all general physical objects which can be independently addressed from an interconnected network. Controller Area Network (CAN) is a kind of serial communication network which can effectively support distributed control or real-time control. This paper proposes the design of an IoT-oriented universal CAN bus. In order to build a complete CAN communication simulation model, message sending and message receiving models are constructed, respectively. The simulation experiment proves that the IoT-oriented network communication model designed in this paper not only has low power consumption, but it can also solve the front-end compatibility problems caused by different communication protocols.

Abstract:The monitoring and treatment of patients in a care unit is a complex task in which even the most experienced clinicians can make errors. A hemato-oncology department in which patients undergo chemotherapy asked for a computerized system able to provide intelligent and continuous support in this task. One issue in building such a system is the definition of a control architecture able to manage, in real time, a treatment plan containing prescriptions and protocols in which temporal constraints are expressed in various ways, that is, which supervises the treatment, including controlling the timely execution of prescriptions and suggesting modifications to the plan according to the patient’s evolving condition. The system to solve these issues, called SEPIA, has to manage the dynamic, processes involved in patient care. Its role is to generate, in real time, commands for the patient’s care (execution of tests, administration of drugs) from a plan, and to monitor the patient’s state so that it may propose actions updating the plan. The necessity of an explicit time representation is shown. We propose using a linear time structure towards the past, with precise and absolute dates, open towards the future, and with imprecise and relative dates. Temporal relative scales are introduced to facilitate knowledge representation and access.
