Control Implementation

This paper presents the virtual environment implementation for simulation and design conception of supervision and control systems for mobile robots, that are capable to operate and adapt in different environments and conditions. The purpose of this virtual system is to facilitate the development of embedded architecture systems, emphasizing the implementation of tools that allow the simulation of the kinematic conditions, dynamic and control, with monitoring in real time of all important system points. For this, an open control architecture is proposed, integrating the two main techniques of robotic control implementation in the hardware level: systems microprocessors and reconfigurable hardware devices. The implemented simulator system is composed of a trajectory generating module, a kinematic and dynamic simulator module, and an analysis module of results and errors. All the kinematic and dynamic results obtained during the simulation can be evaluated and visualized in graphs and table formats in the results analysis module, allowing the improvement of the system, minimizing the errors with the necessary adjustments and optimization. For controller implementation in the embedded system, it uses the rapid prototyping which is the technology that allows in set, with the virtual simulation environment, the development of a controller project for mobile robots. The validation and tests had been accomplished with nonholonomic mobile robot models with differential transmission.

Contemporary computer systems used in the industry are characterized by both an increase in the scale of supported industrial processes measured by the number of control devices and the increasing demand for information describing the underlying processes measured by the number of tags used in Supervisory Control and Data Acquisition (SCADA) systems and Manufacturing Execution Systems (MES). Classical industrial data servers based on the PC architecture are unreliable, expensive to operate and difficult to manage. The alternative is a new standard OPC UA communication interface that simplifies the communication protocol and increases the flexibility of the process data description which allow for the direct implementation of OPC UA servers in embedded devices. This paper presents an innovative approaches in the field of industrial data servers which are used for communication between control systems and SCADA or MES systems. The prototype industrial data server architecture has been implemented, run and tested on the platform of embedded system based on FPGA matrix with built-in FPGA Microblaze processor. The presented experimental results allow to evaluate the applicability of the proposed solution, the limits of the presented architecture and may be used for the improvement of the embedded industrial data servers' structure in subsequent implementations.

In order to meet data acquisition mobility and convenient requirements of the portable ECG monitor, the data acquisition system of ECG with dual CPU is designed in this paper. The system, in which C8051F005 is master CPU, meanwhile ATmega168 is slave CPU, consists of analogical circuit for detecting of ECG, amplifier-filter circuit, A/D converter and SD memory card communication interface mainly. Experimental data shows that the system has such advantages such as good repeatability, high accuracy, quick response and excellent anti-interference. It can effectively detect and obtain electrical activity of the heart and cope with continuous large memory with SD memory card in embedded system. Strong background noises are eliminated effectively by multi-level amplifier and filter; Un-anamorphic ECG can be acquired and recorded synchronously in memory cards. Moreover, this paper also proposes a preprocessing algorithm for noise reduction so that it can reject the interference by respiration and surface EMG signal.

It has been stated in the literature thata test case that needs to be used for testing a distributed embedded system be decomposed into elementary level test cases that can be tested at different computing locations of the system as conducting testing considering entire distributed system is complex as the reliability of testing depends on the environment setting made at each of the location and also the complexity of the communication interface established at each of the distributed location. There should be strategy for conducting testing at each of the locations and comprehend the results to provide wholesome working position of entire distributed embedded systems.In this paper, a strategy has been presented that explain how the testing can be undertaken at individual locations using different test methods and how the results are joined such that the final test results reflects the state of testing a distributed embedded system.
