Abstract: To achieve real-time monitoring for new type of robot motion state, the testing software of robot motion characteristics is studied in this article, based on Linux system, using Qt software compiling. First of all, the new robot prototype and test hardware system are introduced; secondly, the real-time testing curve of displacement, velocity and acceleration are compiled by fitting of the measured data, on the Linux operating system platform, using Qt programming; finally, the testing software run, and its accuracy is verified by experiment.

Abstract: Mobile robot is an important branch in the technological field of the robot.It refers to computer science,automation,mechanism,electronic science etal .In the mobile robot technology research,the mobile robot obstacle detection is one important research aspect of the robot.In this article,by the motor of Shanghai Ingenious Automation Co,Ltd, at first, it measured the distance of the obstacle in front of the robot by using of the ultrasonic sensor and the related software installed inside the robot, analyzed the reasons for the error; and then took the obstacles avoiding experiments by using of the three ultrasonic sensors in front of the robot,the prosess could meet the general requirement,but for the special “table obstacle” which has a hole, the robot drilled into the hole, and could not avoid. Finally, the article gives the conclusion: the ultrasonic sensor alone can not meet the precise identification of the robot on the obstacles, it is necessary to combine with other sensors to improve accuracy of obstacles.

Abstract: Aiming the problem of the armored vehicle's gun control system that there are many kinds of internal devices, complex fault reasons ,but no all-around and online fault diagnosis and state inspection mean, The automatic test platform for the gyroscope group with performance test and fault diagnosis for component and circuit is designed .The platform based on dependency matrix and optimal criterion of the maximum failure feature information entropy optimize test points ,choose optimal test points design. Performance test module is created and provides test result information for fault dictionary in fault diagnosis module. Automatic test platform is able to locate the circuit component failure.The platform is tested by actual vehicle experiment, and the results prove the reliability and validity of the platform.

Abstract: The accurate load identification can ensure the security and reliability of engineering structures. Recently, this technique has attracted much attention by many scholars. This paper concludes the latest load identification technologies at home and abroad, which include the machine learning methods based on neural network method, support vector machine (SVM) and optimization methods, and the wavelet transform method. In addition, their advantages and disadvantages and the applicable ranges are also discussed. Finally, the prospect of dynamic load identification was discussed, so as to extend the application area of load identification. n�GeZ����6�span>dentification

Abstract: Along with an increasingly wide utilization in the fields of ETC application, it becomes more and more important to measuring quickly and accurately on the key equipment of ETC system, such as OBU and RSU. This article is based on the measuring requirement of ETC system and propose a new design proposal by selecting STR715FR0 chip base on the core of ARM7TDMI series and 5.8GHz radio frequency transceiver circuit, the actual operation and test results show that the DSRC device Measuring Instrument works with stability, reliability and low power consumption, which enables convenient and efficient measuring to ensure the reliability and consistency of the ETC key equipment.

Abstract: With the development of computer and network technology, traditional way of examinations because of too many artificial proportion, has become increasingly unsuited to the modern teaching demands. In this paper, used the popular B/S structure, combined with the MVC pattern in Java EE platform, used Apache Tomcat server, MySQL database technology, designed a suitable test database, utilized improved genetic algorithm to achieve automatic test paper, combined JavaBean and Session technical etc. to complete the automatic scoring and evaluation functions. Used the database connection pool to establish efficient connections, utilized regular expressions for user authentication, used Ajax technology to achieve partial-page refresh functions, the design fully reflected the superiority of the Java EE platform.

Abstract: How to ensure the safety of the miners when they are working underground is an urgently problem to be solved. In this paper, we designed a positioning and environment detection system based on RFID and sensing technology. The system can help us to locate the miners’ location and transmit the data of underground environment.

Abstract: In this article, a level ruler Precision Verification System program of the mobile-camera image processing technology that is based on the camera mobile image processing technology is proposed, as a result of the research for the existing barcode type level ruler verification system and a high-precision grating sensor system hardware structure is also built. Secondly, we calculate the uncertainty of the system, and at last do the system stability test that the results show that the system achieves the test requirements. On the barcode type level existing ruler verification system research, proposed a camera mobile image processing technology based on the level ruler of precision calibration system, builds a detection sensor system with high precision grating, realizes automatic acquisition level ruler barcode image, method of application without barcode image with barcode image subtraction the preliminary processing of image acquisition, eliminate the influence of background light on the image acquisition, the uncertainty of the calibration system of the theoretical calculation and experimental verification, the results show that the system achieves the test requirements.

Abstract: This paper takes CC2530 chip as the core, presents the design and implementation process of wisdom baby monitor system based on ZigBee and GoAhead technology, the wireless sensor and control nodes takes CC2530F256 as core in this system, collected and controlled the baby environment data (temperature and humidity, light etc), to do some intelligent processing. At the same time takes GoAhead as the embedded Web technology, The system realized the remote controlling for the equipment in the baby room with relatively low cost, it can constantly adjust relevant parameters for a baby living environment, this also will be the future direction of the development of the Internet of things.

Abstract: This paper covers the current situation of remote monitoring system, combined with the basic features and running environment of GoAhead web server, Put forward the solution to integrate GoAhead web server, Internet, embedded development platform and Linux operation system, design a remote monitoring system. By which the user can monitor voltage and control the stepper motor’s running in real time. The application results show that GoAhead web server reacts rapidly manipulates data quickly. It’s feasible to put into place and to achieve satisfied effect for the management and control of the embedded product.
