Sequential Function Chart(SFC) is very easy to grasp the sequential flow of control logic and has the compatability for a maintenance, In process control, when an error is occurred, to execute other routine by force, we control the process by remote control. In this paper, we proposed the method of select sequence control by remote control in process control designed by Sequential Function Chart(SFC).

The existing remote control system have some inherent disadvantage of direct control in the limit range. In some special cases, for example, a power apparatus, an unmanned factory, a nuclear factory, a security management system, the tele-operation is needed to control remote robot without limit space. This field is based on the Internet communication. Because the Internet is constructed all over the world. And it is possible that we control remote mobile robot in the long distance. In this paper, we developed a remote control system. This system is divided into two primary parts. These are local site and remote site. There are the moving robot and web server in the remote site and there is the robot control device in local site. The moving robot is moved by two stepper motors and the robot control device consists of SA-1100 micro controller and embedded Linux. And this controller is an embedded system. Public personal computer which is connected the Internet is used for the web server. The web server provides the mobile robot control interface program to the remote controller and captures the image for feedback information. In the whole system, a robot control device is connected with moving robot and web server through the Internet. So the operator can control the moving robot in the distance through the Internet.

본 논문에서는 무인차량용 다중채널 무선원격 제어시스템의 설계방안을 제안한다. 기존의 무선원격 제어시스템은 단일 제어채널로 구성되어 제어채널에 고장이 발생하였을 때 응급대처가 불가능한 문제점이 있다. 따라서 휴대용 무선원격 제어기와 스테이션용 무선원격 제어로 구성되는 다중채널 무선원격시스템을 제안한다. 무인차량용 다중채널 무선원격 제어시스템을 개발하기 위하여 휴대용 무선원격 제어기와 휴대용 무선원격 제어기를 설계 및 개발하였다. 개발한 무선원격 제어시스템의 성능을 확인하기 위하여 무인차량에 적용하여 주행 실험을 실시하였다. 무선원격제어기의 고장 시 휴대용 무선원격제어기를 이용한 비상정지 실험과 휴대용 무선원격제어기의 고장 시 스테이션용 원격제어시스템을 이용한 비상정지 실험을 실시한 결과 모두 만족하는 비상정지 성능을 발휘함을 검증하였다.

We describe a research about remote control of mobile robot based on voice command in this paper. Through real-time remote control and wireless network capabilities of an unmanned remote-control experiments and Home Security / exercise with an unmanned robot, remote control and voice recognition and voice transmission are possible to transmit on a PC using a microphone to control a robot to pinpoint of the source. Speech recognition can be controlled robot by using a remote control. In this research, speech recognition speed and direction of self-driving robot were controlled by a wireless remote control in order to verify the performance of mobile robot with two drives.

기존 출시된 가전제품용 리모컨들은 각각의 기능만을 수행하는 것으로 제한되어 있다. 어느 경우에는 리모컨의 수가 너무 많아서 어디다 놓았는지 잃어버리는 경우도 있다. 본 논문에서는 적외선 리모컨을 사용하는 이유와 리모컨의 송신, 수신 방법 리모컨의 변조방식을 연구하였다. 실험은 ATmega128을 이용하여 LCD를 보면서 가전제품(TV, 에어컨 등)을 제어한다. 결과적으로 리모컨 수를 줄이고 하나의 리모컨으로 전자제품을 다루고 나아가 가정 내에 있는 모든 전자 제품을 다룰 수 있기를 기대한다.

In this paper a design and implementation method of remote control system for automobile is presented. For this, we used the Bluetooth technology for remote and wireless communications and microcontroller for system control. By using these techniques, we can design and implement automobile remote control system to improve data error rate, security and application.

This paper suggests remote experiments using the internet for the control education. The remote experiment is composed of equipment server computers, networks accessible to internet, and real plants such as inverted pendulums, crane systems and microcontrollers. Additionally, it requires a server program that has I/O functions with plants and calculate the control, an interface program bridging between web and the server program, and the home page including the detail explanation for the usage. For effective educations, how to perform experiments and how to combine the experiment with lectures will be discussed. The simple experiments by entering a few control parameters and the complex experiments by designing overall controls, will be explained. Technologies related with the remote experiment and other possible remote experiment will be introduced. It is demonstrated that the remote experiment will be very useful, particular for control education where students have difficulties in performing the experiments for lack of experimental equipments.

In this paper, a remote emergency stop system to improve the safety of an automated driving vehicle is proposed. One of the most serious problems of the previous wireless remote emergency system is that it does not work when the wireless channel is damaged in case of an emergency because it is composed of a single communication channel. Therefore, the proposed remote emergency stop system composed of a portable wireless remote system and a stationary wireless remote system is designed and the remote emergency stop system for automated driving vehicles is developed. By applying it to an automated driving vehicle to check it's performance, the wireless remote system is tested. Emergency stops using the portable wireless remote system is tested when the stationary wireless remote system is disconnected. Also, emergency stops using the stationary wireless remote system are tested when the portable wireless remote system is disconnected. The results of the emergency stop test show a satisfactory performance.
