  • 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.

  • Existing system management software solutions show limitations in time and space, as well as problems such as uncertain error messages, and also difficulty providing swift assistance or real time emergency support. Therefore, a wireless remote control system has been designed and implemented in this thesis, which is capable of managing and monitoring remote systems using mobile communication devices (Mobile Phone, PDA, Smart Phone, Webpad) for instantaneous control. The implemented real time wireless remote control system provides remote server management functions, error or event message (unctions, log record functions, authentication function via mobile devices.

  • Many attempts have been made for the health and lives of patients at a remote site. but little attention has been given to emergency system using wireless or other intelligent networks. In this paper, shown is a remote emergency system which can be used in an ambulance. It possibly gives a great help to the patients who may lose their lives, in other words, gives pre-hospital cure to them being sent to the hospital. Doctors or specialists are able to give a quick help which may give a new life to patients. This system deal with very important patient's data-ECG, SpO$_2$, blood pressure, biomedical signal data etc. - as other emergency system. A good performance better than other system is many but shortly spoken as follows. First, this system is user friendly system activated in windows 2000 environment. Second, MPEG4 and ECG data sent to the other station for specilists can give a pre-hospital cure to patients in advance. Third, there exist effective algorithms to operate this system. Fourth, this system has been made with software mostly, so this system can be easily embedded in IBM compatible computer. In addition to this performance, for the better and reliable system, various tests were proceeded and recursively tested. Tests were made in EV-DO wireless network and Local Area Network. This mobile-fixed remote emergency system using wireless network like EV-DO network will give a great usage to needed area.

  • In this paper, we propose a new system for wireless remote control over single-tasking operating systems such as Microsoft's disk operating system(DOS). In order to control a DOS device in a windows operating system, the proposed architecture uses a video transmitter, a virtual network driver, and a wireless keyboard module. Analysis shows that the proposed system, over 15Mbps wireless LAN(802.11n), can transmit at least 10 to 15 video frames, achieves speed up to a maximum of 8Mbps roughly, and is able to satisfy real time processing with respect to key input. Therefore, the proposed system is well suited to a remote control solution based on DOS devices.
