Aimed at the traditional video monitor system is expensive and inconvenient installation, this paper puts forward a design scheme of remote video monitoring system based on embedded system. In the system, the S3C2440 has used as the hardware platform, the open source Linux as the software platform, and a general USB camera has applied to collect and process the video information through the Video4Linux interface provided by core, then, the video will be transmitted to the network via mjpg-streamer streaming media service according to TCP network transmission. The experimental results show that the real-time video effects through the collection and processing have reached the monitoring requirements.
Through the temperature sensor(wet) degrees room temperature data,the single-chip computer(machine) after data processing,display the local temperature and humidity. Microcontroller will be collected by the temperature data through a serial port to the PC for display and judgment,if the temperature is higher than the expected value,through send alarms to a machine,a machine under alert and displays a message. This system can be applied to the factory,greenhouses and other places.
We Discuss the method of using line laser displacement sensor to measure the three dimensional displacement is discussed, avoiding the small measurement range and expensive problems of the conventional three-dimensional laser displacement sensor. This method discusses different methods of measurement depending on the different circumstances, and it is highly flexible, easy to deploy, and relatively cheap. It has a certain research value.
This paper introduces the robot tracking site and installation, discusses the general tracking method, namely double grayscale sensor riding line method and three grayscale sensor line method, These two kinds of method is simple, but in a Intersection and right angle more cases, then there will be a lot of problems, can't even normal tracking. This paper uses the multi gray level sensor control method for tracking. The experiments proved that the robot can be a very good edge tracking walking route, and the effect is very good.
In wireless sensor maintenance difficulties, the fault tolerance ability of the problem is improved,a kind of adaptive control algorithm is put forward based on Fault Tolerant Topology fault tolerance. Firstly,the node fault tolerance index is elaborated,secondly, the various stages of the algorithm is analyzed,and finally through with commonly used algorithm simulation tests results show that, the control effect of adaptive fault-tolerant topology control algorithm has better fault tolerance based, greatly improves the efficiency of the use.
The current conditions of gas metering management is analysed and the gas metering management information system based on B/S structure is designed. The gas metering management information and data analysis is realized through the various functional modules for providing an efficient information management platform of gas metering management.
University English is an important part of higher education, and develop the network university English autonomous learning, can provide a new foreign language learning environment for students, network English learning environment with a large amount of information, the learner has independent thinking and exploration of the space, so that the students in active exploration process, achieve comprehensive quality all-round development effect of.
