Description: 车辆监测用测速雷达是依据多普勒效应原理实现的。由雷达发出一束微波，遇被测目标（车辆）时微波被反射回来，再由雷达接收反射波。如果目标相对于雷达有距离上的运动，反射波的频率将与发射频率发生差异，而这种差异的大小正比于目标与雷达的相对运动速度。于是，雷达通过检测反射波频率和发射波频率的差，就可以计算出被测车辆的移动速度。本次课程设计是利用离散付里叶变换进行频谱分析，设计数字滤波器组，并对滤波器组加窗降低副瓣，通过频域方法测量速度。-Vehicle monitoring using radar gun is based on the realization of the principle of the Doppler effect. By the radar emits a microwave, in case the measured target (vehicle) when the microwave is reflected back, and then by receiving the reflected radar waves. If the target relative to the radar on a distance of motion, the frequency of the reflected wave and the emission frequency of the difference, and this difference is proportional to the relative target and radar velocity. Thus, by detecting the reflected radar wave frequency and the frequency difference between the transmitted wave, we can calculate the movement speed of the vehicle under test. This course is designed to take advantage of the discrete Fourier transform spectral analysis, digital filter design group, and filter bank windowed lower sidelobes by frequency domain methods to measure speed.

-Pedestrian collision avoidance in urban environments is an important active safety technology to protect vulnerable
road users and realize zero-traffic-accident society. Especially, reduction of vehicle-pedestrian collision accidents at
intersections by using vehicle control engineering approaches in a promising approach. This paper focuses on the right
turn driving situation which drivers need to negotiate pedestrians near crosswalk region. Using a micro electric vehicle as an experimental vehicle, this paper describes an autonomous collision avoidance by braking. The intensity of braking
maneuver is determined by Potential Fields. A LIDAR is used to detect pedestrians and measure their speed and
position in intersections. The proposed system consists of the risk assessment in consideration of pedestrian motion and
an algorithm to minimize the collision risk which changes dynamically associated with changes of pedestrian behavior.Finally, the effectiveness of the autonomous coll Platform: |

Description: 该系统由霍尔速度传感器、微波雷达测距传感器、雨滴感应器、雨量传感器、报警装置等模块组成，采用52单片机和DSP作为数据处理单元。汽车的制动距离受路面附着系数和车速的影响，因此用测速传感器和雨量传感器来测速和确定路面附着系数进而确定汽车的制动距离。用测距传感器测得的跟车距离与制动距离相比较进而判断汽车行驶时是否存在安全隐患。雨量传感器和测距传感器不需要在汽车的任何行驶条件下一直保持工作状态，因此该系统采用两个单片机将各传感器分隔在两个子系统中，第一个单片机根据雨滴信号和速度信号通过继电器来控制测距雷达和雨量传感器电源的通断。采用两个子系统可以减少系统发热和降低功耗。(The system is composed of Holzer speed sensor, microwave radar ranging sensor, rain drop sensor, rain sensor, alarm device and so on. The 52 microcontroller and DSP are used as data processing units. The braking distance of the vehicle is affected by the coefficient of road adhesion and the speed of the vehicle. Therefore, the speed sensor and the rain sensor are used to speed up and determine the coefficient of road adhesion, and then determine the braking distance of the vehicle. The distance measured with the distance sensor is compared with the braking distance, so as to judge whether there is any hidden danger when the vehicle is running. The rainfall sensor and ranging sensor does not need to keep working in any driving condition of the vehicle, so the system uses two microcontroller to each sensor and separated into two subsystems, the first single-chip based on Raindrop signal and speed signal through the relay to control measure) Platform: |
