81.使用数字全息技术对透明材料的特征测量
[非金属矿物制品业,信息传输、软件和信息技术服务业] [2015-07-24]
Digital holography is applied to measure the characteristics of transparent material. A digital hologram recording system to measure the surface of transparent material was established, and the digital holograms of transparent object were obtained in high quality. For postprocessing of hologram, the least-squares phase unwrapping algorithm was used in phase unwrapping, and the phase reconstruction image of transparent object was obtained. The information of material surfaces was measured and the characteristic was presented in 3D visualization. The validation experiment was conducted by NanoMap 500LS system; the results of validation experiment are well satisfied with the measurement by digital holography, which proved the feasibility of digital holographic technology as a good measurement tool for transparent material.

82.基于BP神经网络的CNG汽车的注气控制
[汽车制造业] [2015-07-22]
Compressed natural gas (CNG) automobile is an emerging new energy car.How to control gas injection is the key technology of CNG electronic control system.At present,the control based on the MAP graph is used usually,but this control method has some shortages,for example larger data,poor adaptive capacity and difficulties in data updating.BP neural network control has adaptive and self-learning,nonlinear processing ability and high generalization,and faults tolerant ability in processing information.In this paper,BP neural network is used to control natural gas injection in order to solve the shortage of the MAP picture control.Simulation experiment shows thefeasibility and advantage of this method.

[汽车制造业,计算机、通信和其他电子设备制造业] [2015-07-22]
In this paper we propose a intelligent vehicle system design with MK60NS12VMD100 as the micro-controller unit and CMOS image sensor to obtain image information of the track.Our proposed comparator circuit instead of an A/D conversion to obtain the binary image enables us to achieve a bigger field of view and a higher processing speed.A unique algorithm to extract track information and to successfully extract the black guide line is devised.We also design a PID closed-loop control to adjust the rotate speed of driving electromotor and direction of steering electromotor.The results indicate that our design proposal is feasible.The intelligent vehicle could successfully achieve a high speed,while maintaining an excellent stability.

[交通运输、仓储和邮政业,信息传输、软件和信息技术服务业] [2015-07-22]
In this paper,based on Kalman filtering algorithm,a method of target vehicle motion state radar estimation with radar(or lidar) is presented.The state equations is established based on rigid plane dynamics theory,and then with a Kalman filter to do radar data processing,the position,velocity and acceleration of the target vehicle can be estimated at the same time,so that to cover the shortage that acceleration information can not be gained with radar system.Through simulation and field tests it is verified that the detection accuracy of position and velocity of target vehicle is increasing,and the acceleration of target vehicle can be estimated effectively and accurately.

[信息传输、软件和信息技术服务业,汽车制造业] [2015-07-22]
A global route planning method for intelligent vehicle is presented here based on the comparison,selection and development of classic figure search algorithms.In addition,the effects of traffic signs in road network are also be considered in the method,so to insure that any traffic laws such as steering or passing through is violated.With the testing results,the method in the paper can decide an effective(or shortest distance) and legitimate global route for intelligent vehicle's driving guide,and the algorithm is running efficiently enough to meet the real time need when it should work temporarily during vehicle driving.
