In recent years, video data acquisition and wireless communication are increasingly applied in the field of intelligent transportation and environmental monitoring due to its promising capability. A design of data acquisition and communication system based on embedded technology is proposed in this paper. The architecture is discussed, and the detailed design of the system is given including hardware and software solution. Chip S3C6410 and DM642 were considered as the core of information acquisition and processing. Acquired data was sent to database server on control center with integrating wireless mobile network (CDMA). Through the main page of the website based on LAMP technology, it can realize the remote access of sensor monitoring data and control the devices on the vehicle. It also supports the query of the historical records and download of the acquisition data to the client according to requests. Experiment results show that the working performance of the system is quite stable and can reach the design requirements in real-time data acquisition and remote control. Furthermore, the system has the characteristics of good expansibility, networking flexibility and low cost. The design gives a new way to collect the video data of environment instead of the traditional way using wires or manually.

Can-Sized satellite (canSAT) is a small satellite that is used for educational purpose. CanSAT offer student to build their satellites with their creativity which make the learning process more effective. In Malaysia, SiswaSAT is held by the Malaysia Space Agency for students in different categories to participate and build their satellites according to rules set and it should be a low-cost project. CanSAT can be divided into few parts which are communication system, onboard data acquisition, ground control station and power system. The power system is one of the important and heaviest subsystems, it needed to supply power, but weight and size are one of the main concerned as the canSAT should not exceed the required weight and selecting power supply that is matched with the overall power budget that has small size and lightweight is challenging. Therefore, the power supply selection should consider this detail. The power distribution design should be able to supply an appropriate amount of current and voltage to the components according to their specification. This study aims to develop and test the proposed prototype which is named ScoreSAT able to provide data and have enough power supply for the whole operation. Therefore, an initiative to develop the appropriate power distribution design for canSAT is taken to overcome the problem of the power system. Moreover, each subsystem needs to be tested by obtaining the results from the onboard data acquisition and transmit the data using the communication system before integrating into the power system. ScoreSAT prototype needs to carry the system that is mounted inside, thus the space inside the prototype needs to be fully utilized for the whole system to fit in. ScoreSAT completes the mission by obtaining data acquisition during the operation.

Building energy consumption monitoring and management system have been developed widely in China in order to gain the real-time data of energy consumption in buildings for analyzing it in the next state work. This paper describes a low-cost and small-sized collector based on the STM32 microcontroller, which can be placed in a building easily to implement the work of data acquisition, storage, and transmission. The collector gathers the electricity, water, heat, and energy consumption data through the RS485 field bus and stores the data into an SD card with mass storage, finally, using Internet to finish the communication and transmission to data server through TCP protocol. The collector has been used in application for two years, and the results show that the system is reliable and stable.

With the development of computer technology and power grid, integrated dispatching automation system has been gradually applied and used, for it has made considerable progress in technological advance and functional reliability. A method of real-time data acquisition and exchange that adapts to integrated dispatching automation system is proposed, which follows the principle of distributed collection and centralized use. It makes full use of dispatching data network and service bus, to achieve the integration of point multi-source data processing, data forwarding and data remote access, under the situation of normal operation or network failure.

The previous measuring methods have the disadvantages of big workload, inaccuracy, high expenses and so on. A set of remote monitoring system that monitors soil moisture is developed by configuration software. This system makes online monitoring soil moisture, dynamic display of real-time data, historical data query and remote access come true. The test results in Haikou show that the system not only meets the requirements of monitoring soil moisture, but also is featured with good stability, accurate data and data sharing. It can be applied in many fields when changing the necessary sensors. The system is scalable and low-cost.

The information monitoring points for greenhouse environment were scattered, so a wireless sensor network with star-type network topology was designed and the wireless monitoring system for greenhouse was developed. By employing CC2430 chip as the core hardware, WSN implemented real-time data acquisition and remote wireless transmission. The field data was transmitted to the monitoring host through RS-232 interface. The node management software was developed based C language and the data management software was developed using LabVIEW 8.6. The system was featured by low cost and simply installation. The primary experiments show that the system performance is stable and can meet the design requirement of remote data acquisition.

Not everyone can afford to own and operate a scanning electron microscope. Everyone can, however, access images and instruments in a variety of ways, depending on the objective. Remote access capability is a result of recent developments in desktop computers, software, and the World Wide Web. Some of these developments and some suggestions for future resource development will be reviewed here.With the arrival of commercially available, digitally controlled SEMs in the 1980s, it became possible to control microscope operation with a desktop computer and the appropriate software. By connecting a desktop computer to the microscope via the Internet or dedicated data lines such as ATMs, remote control of microscopes became a reality. Although analog microscopes are not as readily controllable over the Internet, their video data stream is easily captured, digitized, and dispatched to remote observers using low-cost consumer video conferencing programs. These approaches enable users at one location to observe their samples in a microscope located elsewhere. However, transfer rates over the Internet fluctuate wildly depending on network traffic, at times making remote access or control almost impossible. Dedicated data lines ensure a relatively stable transfer rate, but at a significantly higher cost.
