  • As the internet communication is prevalent in recent years, it becomes quite possible to monitor and control some mechanical plants from the remote place through the TCP/IP communication. Such a concept is expected to be applied to many industrial systems for easy maintenance and trouble shooting as well as various kinds of expensive test equipments for sharing. In this research, remote data monitoring and speed control for a DC-motor is implemented and tested through TCP/IP communication with embedded micro-controllers. It showed the possibility of reliable remote control system design utilizing the internet communication.

  • In this paper The embedded Web or Hypertext Transfer Protocol (HTTP) server allows embedded systems developers to take advantage of a network infrastructure that is already in place to enhance their designs and provide new features for their customers. It has gained acceptance as a protocol for gleaning information from a wide variety of sources and its open extensible nature makes it suitable for the full range of networked embedded systems. Many companies are already building Web browser support into smart-phones and network computers, but the other end of the connection also has great potential for many more classes of embedded system. Once fitted with an embedded Web server, a device can report its status to any client on the network and can even be reprogrammed remotely to perform new tasks.

  • We have designed embedded web server system and ported Linux operating system version 2.4.1 at our system. And then We implemented to control and monitor widely separated hardware. Web server is the Boa web server with General Public License. We designed for this system using of Cirrus logic's EP7312 ARM core base processor and connecting input and output device at GPIO port of EP7312. Device driver of General purpose I/O for Linux OS is designed. And then the application program controlling driver is implemented to use of common gate interface C language. User is available to control and monitor at client PC. This method have benefit to reduce the Expenditure of hardware design and development time against PC base system and have various and capacious application against firmware base system.

  • This paper is dealing with how to control of a client robot's movement for instructions from a server PC and a wireless andremote control Robot that sends the server information of images for monitoring. To implement this. 802.11x WLAN with TCP/IP socket programming is used to get the driving instructions from the server PC and control movements of the robot such as a forward, backward and directions. As well as this, ARM9 cored PAX255 embedded processor and Linux OS is used for the function transmitting BMP format of 320 ${\times}$ 240 pixel for stopped image data.

  • XML Web Services are a distributed computing component which enables users to use services existing in remote places by using a standardized language called XML. Web Services were developed as the cooperation and business scales between companies as businesses had been widened due to the improvement of internet services. For this reason, enterprise sized Web Services are mainly used at present. But as the number of Internet users has been increased, they became in need of more diverse services, and providing individual Web Services are also being more emphasized. Therefore, an Embedded Web Server for personal Web Services for embedded systems such as cell phones had been implemented in this paper. This paper shows the possibility of building up a small, personal sized Web Services Server not the enterprise sized one by doing real implementation.

  • An embedded system has been applied to many fields including households and industrial sites. The embedded system is implemented fur image tracking in security area. This system supports a fixed IP far the reliable server operation on TCP/IP networks. A real time video image on the is analyzed to detect a certain invader who jumped into the observed area. The digital camera is connected at the USB host port of the target board. The video images from the video camera is continuously analyzed and displayed at the Linux web-server. The moving vector of the invaders on the continuous image frames is calculated and then it sends the calculated pan/tilt movement. That used Block matching algorithm and edge detection algorithm for past speed. And the displacement vector is used at pan/tilt motor control through RS232 serial cable. The experiment result showed tracking performance by the moving part speed of 10 to 150 pixels/sec.

  • Nowadays, people perform their tasks anywhere anytime using their mobile devices. For this reason, data synchronization (DS) between mobile devices and a central server has become one of the most essential technologies in mobile environments. Currently, several mobile DS protocols are proposed and used. However, the existing DS protocols cannot guarantee interoperability between them. To solve the problem, an embedded DS gateway has been developed in our previous study. The gateway runs on a Windows Mobile-based emulator. It converts data on a mobile device into common data specified by OMA DS standard protocol and vice versa. The embedded gateway has been built to support the OMA DS standard protocol. In order to verify that the embedded gateway conforms to the OMA DS standard protocol, two kinds of OMA conformance tests have to be conducted - interoperability test with an OMA DS-based server and conformance test with SCTS (SyncML Conformance Test Suit). In this paper, some parts of the gateway previously built are modified and the modified gateway is installed on a Windows Mobile-based smart phone. And the interoperability test and the conformance test with the SCTS are conducted. The results of the tests show that the embedded DS gateway operates properly on the Windows Mobile-based smart phone and that the gateway passes the tests, verifying its conformity to the OMA DS standard protocol. In addition, DS performance tests show that DS delay times between a real smart phone and a DS server increase gently as the number of DS data increases. In other words, the embedded DS gateway built in this paper can be used for a real smart phone at a reasonable performance cost.

  • Most of the traditional embedded web server systems have been designed for monitoring and controlling some dedicated equipments. Hence, not only they have no generality and flexibility but also they are too expensive for the lower-cost domestic equipment. To cope with these difficulty, we suggest a lower-cost ${\mu}$-embedded web server model which is suitable for monitoring and controlling the industry or house equipments by using the internet. The suggested model is based on an one-chip ${\mu}$-processor in which the ISP (In-System Programming) function and flash ROM are embedded basically to minimize the cost of H/W and S/W. Also it allows to add an new function dynamically to provide the generality and flexibility. Finally, to evaluate the feasibility of the suggested model, we have manufactured a test-board based on the ATMega103 ${\mu}$-processor and programmed the control program and tested it on the MS Explorer 5.0 environment.
