For the flight velocity of some UAV is high and the practice operation is much complex, the ground station keyboard based on multi-thread technology is designed. Also the keyboard is on the base of MSComm control in VC++ 6.0. There are two threads in this keyboard. According to the Serial Communication Protocols defined original the main thread accepts and transfers ground station command and GPS information. At the same time, the other thread scans matrix keyboard from which the UAV sends remote control command. The experiments testify that the keyboard can control UAV smoothly; meanwhile it is easy to operate for its simple configuration.

In this paper, we mainly introduce the serial communication between PC and FPGA and adopt the design principles of DDS phase accumulator to achieve small error of baud rate generator and provide the reliable data transmission. On PC, we use the Labview software to design control interface, which is responsible for sending the control command. The experimental results indicate that the communication is feasible, high stability. This design is applied to the control unit of waveform generator based on FPGA by inputting relevant data on PC such as waveform selection, frequency control, range control and phase control to realize the function of waveform selection, amplitude modulation, phase modulation and frequency modulation.

Generally we use simple led regular static type display screen to deliver the message. Previously, to update the data either it may be large one it takes a long process to update data. Now a days scrolling type displays are more preferred over the static type displays. By adopting a programming device called NODEMCU, data can be displayed on dot matrix in scrolling manner. By adopting led 8x8 dot matrix using can controlled via IoT based system which controlled by mobile or laptop. Scrolling type text display boards, projects uses led dot matrix displays or regular outside purpose digital sign boards. The message scrolling displays are also type of scrolling LED display examples, presented here are nodemcu based led matrix display project. The led matrix is controlled using nodemcu by serial communication protocols. In this pair of 8*8 led Matrix display modules have used to display the transmitted message on Matrix display. nodemcu is heart of this project. The nodemcu is the transmitter to send data, and the receiver is led matrix display to display message on it.

Abstract. The Double Star Programme (DSP) was first proposed by China in March, 1997 at the Fragrant Hill Workshop on Space Science, Beijing, organized by the Chinese Academy of Science. It is the first mission in collaboration between China and ESA. The mission is made of two spacecraft to investigate the magnetospheric global processes and their response to the interplanetary disturbances in conjunction with the Cluster mission. The first spacecraft, TC-1 (Tan Ce means "Explorer"), was launched on 29 December 2003, and the second one, TC-2, on 25 July 2004 on board two Chinese Long March 2C rockets. TC-1 was injected in an equatorial orbit of 570x79000 km altitude with a 28° inclination and TC-2 in a polar orbit of 560x38000 km altitude. The orbits have been designed to complement the Cluster mission by maximizing the time when both Cluster and Double Star are in the same scientific regions. The two missions allow simultaneous observations of the Earth magnetosphere from six points in space. To facilitate the comparison of data, half of the Double Star payload is made of spare or duplicates of the Cluster instruments; the other half is made of Chinese instruments. The science operations are coordinated by the Chinese DSP Scientific Operations Centre (DSOC) in Beijing and the European Payload Operations Service (EPOS) at RAL, UK. The spacecraft and ground segment operations are performed by the DSP Operations and Management Centre (DOMC) and DSOC in China, using three ground station, in Beijing, Shanghai and Villafranca.

This paper introduced to develop and implementation of PC based controller for humanoid robot using digital potentiometer. The main objective in this paper is to develop and implement the joystick controller by using a digital potentiometer circuit board that be able to control the humanoid robot movement. The Arduino board and digital potentiometer will be integrated by connecting both pins in between wiper, W pin and ground, GND to the DB9 pins of remote control platform, which is TX and RX pins respectively. Humanoid robot as known as TOMY i-SOBOT is used as a preferred model due to wide usage in many applications. A digital potentiometer will be transmitted the voltage and current value depend on the digital level through serial communication to give the instruction for humanoid robot movement. The humanoid movement based on Guided User Interface (GUI) where the user give a commands by pressing the button on the GUI such as turn left, right, forward, and reverse. The results show that the humanoid movement able to control based on the voltage and current in a digital potentiometers value.

Scanning Electron

Recently, SEM (Scanning Electron Microscope) and the other observation devices are coming to use a LAN (Local Area Network) to save the image in the database. We developed a remote control system in which SEM image and Control interface is indicated on the WEB Browser. in this system, SEM can be controlled by an external (client) PC installed in a general WEB Browser(Internet Explorer). Accordingly, operation interface can be indicated on the WEB browser.A JSM-6700F is connected to a LAN, and so the microscope can be controlled by a client PC. Figure. 1 shows the block diagram of SEM remote control system. The JSM-6700F has two lines to the LAN for image transfer and communication with the SEM control. in order to transfer the image, the image size squeezes from 1280 × 1024-pixels (SEM image size) to 640 × 480-pixels for quick transfer. The image signal (640 × 480-pixels) is connected to the video server only, and then the image transfers to the client PC via LAN . The SEM control communicates with client PC for external command. On the other hand, the SEM control interface and the image are indicated on WEB Browser (Internet explorer) as shown Figure 2. The SEM control interface is composed of the SEM image area and the SEM control part. The SEM image indicates the 640×480-pixels live image. This pixel number was an image quality sufficient to adjust the focus. When a high quality image is necessary, the image of 1280 × 1024-pixels is saved on the the SEM(server) side by choosing the image save button.

A gateway based on ARM is presented to achieve mutil-protocol conversion among different electronic control units. To guarantee its real-time ability and stability, the μC/OS-II embedded operation system was adopted. The first-in-first-out data queue is used to balance the communication rate among the different communication protocols which consist of the Controller Area Network, TCP/IP and RS-232. The gateway can be used in remotely manipulation between the console with Ethernet and remote underwater vehicle with other serial communication protocols.
