Abstract: The intelligent monitoring system of battery with CAN bus is introduced, which is composed of two layer net, the C8051F045 controller is the core of measuring system, the bottom layer is measuring board based on intelligent battery monitor DS2438 fixed on each battery, it measures the battery parameter such as voltage, current and temperature on line, exchanges dates with C8051F045 by the single bus. The top layer is the CAN bus, by which connected the super monitoring compute and C8051F045 controllers. The system can real-time measure battery parameters remotely, forecast accurately the invalid battery according to the comprehensive judgment, and can improve the reliability of the serial battery.

Abstract: This paper presents a type of architecture of multistage machining processes in small batch mode, named Small-batch Quality Control System (SQCS), through analyzing various process quality control methods. The SQCS integrates complex network, workpiece variation propagation model and process quality prediction. And then, the three key enabling technologies are discussed in detail. Sensor network could be used to acquire real-time quality data, which include workpieces’ physical and dimensional information. Based on the above mentioned ideas, a general model of stage flow in small batch mode is constructed in order to realize process-driven online quality control and improve product machining quality.

Abstract: To eliminate the errors of cylinders’ dynamic output positions of master side for the influence of random disturbance of slave side, master-slave position controller based on disturbance state observer optimal control and robust dynamic compensate PD feedback control algorithm is designed for electro-hydraulic servo tele-robot. A linear quadratic with disturbance observer and a dynamic robust compensator position controller is developed. Experimental results demonstrated the proposed algorithm is availability and showed that the designed controllers both improved position tracking precision for master-slave side and possessed good adaptive ability and robustness in existence of uncertain disturbance, enhanced the operational performance.

Abstract: Digital image has a large quantity of image data and long time for transmitting. It affects the real-time of the teleoperation robot system. According to the basic principle of human eye identifying objects and image blurry processing, a new image processing method of simulating human eye range of interest (ROI) is proposed. The method uses the calibration algorithm of three-dimensional stereo target and the Gauss blurred principle. The non-ROI region is blurred to hierarchy for extracting the feature and measurement to finish the image processing tasks. The experimental results showed that the quality of the images was assured and the transmission time was shorted. The real-time of the teleoperation robot system was also guaranteed.

Abstract: A new 3-CRR parallel mechanism which was complete decoupling for the design of transplanting seedlings had been proposed, and its kinematics was analyzed. The anticipant trajectory had been transformed into generalized location coordinates of driving joint. The intelligent control of the computers within the scope of the work had been completed. In closed-loop control circuit, the improved feed-forward compensation fuzzy PID control principle was adopted. By detecting encoder’s feedback signals, continuous trajectory interpolation had been used to achieve the precise control of the robot joints. An intelligent self-searching transplanting robot was developed, the robot automatically calculated the coordinates of the roots of seedlings and automatically generated transplanting trajectory in the humanoid intelligent way. Modular design and object-oriented programming methods were mainly used in the control system of transplanting seedlings robot, and it was compiled by VC + +6.0.

Then the authors list two kinds of reliability analysis methods and describe their features. Based on the characteristics and the control level of station BAS, finally, we achieve reliability analysis, which has scientificity, rationality and practicability, and can be helpful for guiding the maintenance, design, and further perfect of BAS system.

Abstract: A dynamic model and numerical method which was in the underwater vertical launching process have been built, and the missile which was on the effects of the lateral flow was simulated with its movement and load. The results showed that: the model is feasible; adapter compressive stiffness and its layout in the tube has a greater impact on the movement and load of the missile; fluid added mass effect is not negligible; the lateral movement of the missile’s launching process was along with a large shock , so we must attach importance to the problem of vibration. lateral flow

Abstract: In order to realizing real-time on-line oil monitoring for high-power gearbox’s wear state during operation, a monitoring system is developed on the basis of the ferrograph sensors in this paper. By means of a multi-level monitoring system, a real-time remote monitoring and analysis system of unattended machine wear condition is achieved which can real-time display the image of the wear particles and the wear information of the gears, thus getting such advantages as timely notice and warning, reducing equipment’s damage and maintenance costs . The initial application of system on the real machine shows good results and effects.

Abstract: The digital probe instrument is used for measure the microwave impedance of electronic circuit, which request both the precision and resolution of 3d displacement of the probe at the level of 1~2μm.As there are a lot of the points to be measured, it is a high labor intensity and low efficient work when person moving and positioning the right position through high magnification microscopy only by eyes, as well as some points that should be measured are easily ignored. A double-3d displacement sliding table consists of grating digital system is proposed in the paper, which could solve the problems successfully.

Abstract: With the development and maturity of intelligent buildings, energy conservation become a trend, lighting control systems are becoming increasingly popular. At the same time with the rapid development of electronic technology, microcomputer as a subject and core for embedded control systems, instead of the traditional conventional electronic circuits of the control system, based on single chip microcomputer control system has been widely used in intelligent building. This text directs against the power consuming wasting phenomenon of public place, regard AT89C51 as the core, propose a measurement for Pyroelectric infrared sensor and light combination of intelligent lighting control system. By judgment on the light intensity and indoor if someone automatically switch lights, achieve the purpose of energy saving.
