Study of Remote Elevator Monitoring Fault Detection System

Remote Elevator Monitoring (REM) is an important means to ensure elevator secure, reliable working. In this paper, an elevator remote monitoring control scheme is proposed based on multi-threaded technology. Due to all threads in the multi-threaded technology may visit the same overall situation object and the shared resource, center system communicates with embedded terminal is achieved by the method. The remote elevator monitoring system has been designed based on the multi-threaded technology; the main thread interface function is realized by monitor center software, other management operations are also executed in the system. The test results show that the multi-threaded technology applies to the monitoring system, which enhances the system efficiency and security.

Design and Implementation of RF Deployed SMS Based Equipment Controller

Short messaging Service (SMS) is popularly used to provide information access to people on the move. This has resulted in advances in mobile communication bring great effects on people’s life styles. This paper describes the implementation of a remote control scheme, remote control system via SMS, which controls home and factory devices in short distance and long distance, respectively. This paper proposes a SMS-based protocol, which is designed with the mechanisms of reliable transmission and information encryption, thus it is capable of the implementation of secure and reliable control. This paper mainly focuses on the controlling of home and factory appliances remotely. The system is SMS based and uses wireless technology to revolutionize the standards of living. As the system is wireless therefore more adaptable and costeffective. The whole system is controlled by a PIC microcontroller. We can control a good number of systems or devices by this method.

The moving object monitoring and transforming personal robot system based on remote controls is designed and implemented, and the performance of the system is analyzed in this paper. The major considering factors in the system design are such as 1) the control scheme design (button based and the remote control schemes); 2) the operation modes design (wheel driving mode/pedestrian mode/auto driving mode/observation mode); 3) the remote control function design; 4) the design of the monitoring function of the changes in neighbor environments; 5) the design of the detection of obstruction. From the experiments, it is assured that the developed personal robot can walk to the grounds that covered with doorsill or electric wires in indoors by control the leg articulations, and can escape from the obstruction using three infrared sensors in the 30cm*30cm obstruction styled space under the auto driving mode.

Remote Control for ROADMs in IP-over-CWDM Networks

Remote control scheme for the ROADMs (Reconfigurable Optical Add/Drop Multilplexers) were designed, and 3 sets of the ROADM were manufactured for use in IP-over-CWDM networks. The control performance was examined, and lightpaths could be reconfigured successfully by the control.

QoS-Based Remote Control of Networked Control Systems Via Profibus Token Passing Protocol

This paper focuses on a quality-of-service (QoS)-based remote control scheme for networked control systems via the Profibus token passing protocol. Typically, token passing experiences random network delay due to uncertainties in token circulation, but the protocol has in-built upper and lower bounds of network delay. Thus, to ensure the control performance of networked control systems via the Profibus token passing protocol, the network delay should be maintained below the allowable delay level. As the network delay is affected by protocol parameters, such as target rotation time, we present here an algorithm for selection of target rotation time using a genetic algorithm to ensure QoS of control information. We also discuss the performance of the QoS-based remote control scheme under conditions of controlled network delay. To evaluate its feasibility, a networked control system for a feedback control system using a servo motor was implemented on a Profibus-FMS network.

Automatic adaptation of mobile applications to different user devices using modular mobile agents

Wearable, handheld, and embedded or standalone intelligent devices are becoming quite common and can support a diverse range of applications. In order to simplify development of applications which can adapt to a variety of mobile devices, we propose an adaptation framework which includes three techniques: follow-me, context-aware adaptation, and remote control scheme. For the first, we construct a personal agent capable of carrying its owner's applications. Second, we design a personal agent capable of carrying applications with an adaptable hierarchical structure. Then, applications can be adapted approximately to the context of evices by using an attribute-based component decision algorithm. Finally, to achieve a remote control scheme, we distribute the computational load of applications on the resource-restricted mobile devices. An application is divided into two parts that can be executed on a user device and a server separately. In short, this framework facilitates the development of widespread applications for ubiquitous computing environments. Furthermore, it enables the applications to follow their owners and automatically adapt to different devices. Copyright © 2005 John Wiley & Sons, Ltd.

Space Robotics For Interplanetary Missions

Advanced in-situ exploration missions to the other planets of our solar system are now following the earlier remote observation satellites. The related material sampling tasks raise challenges in robotics and control engineering in order to deal with the uncertainties of the environment. The significant signal propagation delay requires autonomous control strategies to be implemented on the space probes in order to adaptively react in time critical situations to the encountered environment. Even in standard situations innovative remote sensor data acquisition and remote control schemes dealing with the delays are to be implemented. This lecture will address the control aspects of the specific European interplanetary missions like HUYGENS (part of Cassini) to Saturn/Titan, ROSETTA to a comet and also planetary rovers for surface exploration. At these examples, techniques related to control with delays, adaptive control, navigation, emergency identification and recovery are addressed, which are of crucial importance for mission success.

Autonomous Navigation of Rovers for Planetary Exploration

For planetary surface exploration, micro-rovers are very attractive to provide mobility functions at small mass requirements. This paper summarises the requirements for a Mars-rover and outlines the control concepts for navigation. In this context autonomous reaction capabilities are necessary, in combination with remote control schemes, to deal with significant signal propagation delays. Specific navigation aspects addressed in this paper include path tracking, instrument fine positioning and hazard avoidance. Finally test facilities to validate these concepts in simulations on Earth are reviewn.

Remote Metering and Automatic Load Control

Power dispatching on an interconnected electric power system has been simplified and greatly improved by the adoption of a remote metering and automatic load control scheme recently developed. Remote metering at the power dispatching center provides continuous indication of the load on a distant 110-kv interconnection. The equipment also provides automatic control of the load on a hydroelectric generating plant located 160 miles from the metering point. The scheme, operating over company owned telephone lines, is based upon maintaining a constant beat frequency in the receiving apparatus, the transmission frequency being varied. Maintenance cost of the equipment is found to be negligible.
