本发明属于交通设备领域，具体涉及一种急弯道路显示屏预警系统及其方法。The invention belongs to the field of traffic equipment, and in particular relates to an early-warning system and a method thereof for a display screen on sharp curves.
背景技术Background technique
急弯道路视距不良和汽车超速行驶，容易发生交通事故。因此，管理者经常采用安装反光镜的措施来预防事故。但是，反光镜成像失真度较高，容易造成驾驶人对对向来车情况的误判，反而导致交通事故，尤其是山区道路经常出现大雾、雨雪天气，驾驶人很难看清弯道反光镜；夜晚驾驶人视距变短，弯道反光镜的效果几乎为零；反光镜易污染，无人清理镜面上的污渍，易造成视觉不清；同时，反光镜还容易变形和破碎，易造成视觉错乱等弊端。Poor sight distance and speeding cars on sharp curve roads are prone to traffic accidents. Therefore, managers often adopt the measures of installing reflectors to prevent accidents. However, the image distortion of the reflector is high, which may easily cause the driver to misjudge the situation of the oncoming vehicle, and lead to traffic accidents, especially in mountainous roads where heavy fog, rain and snow often occur, and it is difficult for the driver to see the reflector on the curve. ; At night, the driver's sight distance becomes shorter, and the effect of the curve reflector is almost zero; the reflector is easy to be polluted, and no one cleans the stain on the mirror surface, which may easily cause blurred vision; Disadvantages such as visual confusion.

弯道LED显示屏设有延时程序，延时结束后，弯道LED显示屏返回显示安全驾驶提示。The curve LED display has a time-delay program. After the time-delay ends, the curve LED display will return to display safe driving tips.
弯道LED显示屏的优势在于显示内容丰富，且可根据需要编辑内容；或在特殊路况和天气时进行其它信息的显示。本发明的实施例中，当汽车进入此范围内时，对向车道显示屏提示“前方来车”，当本车超速时则本车道LED显示屏提示“您已超速”，在没有超速和对向无来车时，则LED显示屏提示“急弯道路、谨慎驾驶”，适时将这些信息反馈给驾驶人。The advantage of the curved LED display is that the display content is rich, and the content can be edited as needed; or other information can be displayed in special road conditions and weather. In the embodiment of the present invention, when the car enters this range, the display screen of the opposite lane will prompt "the car ahead", and when the vehicle is speeding, the LED display screen of the lane will prompt "you have exceeded the speed". When there is no oncoming vehicle, the LED display will prompt "sharp road, drive carefully", and timely feedback this information to the driver.

弯道LED显示屏一般面积不大，安装结构应充分考虑到抗风、抗震、承载等主要因素；其次是屏体的形状、结构、外装饰设计应该和所依附的杆件或物体相协调；再者，要考虑当地的环境因素，比空气湿度、空气盐碱含量等等。Curved LED displays generally have a small area, and the installation structure should fully consider the main factors such as wind resistance, earthquake resistance, and load bearing; secondly, the shape, structure, and exterior decoration design of the screen body should be coordinated with the attached rods or objects; Furthermore, local environmental factors should be considered, such as specific air humidity, air salinity, and so on.
在本发明的实施例中，本发明的弯道LED显示屏采用户外双色显示屏；像素构成：1R1G；像素间距：10mm；亮度：﹥5500cd/㎡；模组尺寸：320mm×160mm；可视角度：水平120°垂直120°；模组解析度：32×16；工作寿命：﹥100000小时；平均功率：230W/㎡；刷新频率：480Hz；像素密度：10000/㎡；驱动方式：恒流驱动；扫描方式：1/4扫描；可视距离：﹥10m；模组材料：黑色PC面罩、PC背板；最大功率：650W/㎡；输入信号：USB、网口等。In the embodiment of the present invention, the curved LED display screen of the present invention adopts an outdoor two-color display screen; pixel composition: 1R1G; pixel pitch: 10mm; brightness: >5500cd/㎡; module size: 320mm×160mm; viewing angle : Horizontal 120°Vertical 120°; Module resolution: 32×16; Working life: ﹥100,000 hours; Average power: 230W/㎡; Refresh frequency: 480Hz; Pixel density: 10,000/㎡; Driving method: Constant current drive; Scanning method: 1/4 scanning; viewing distance: >10m; module material: black PC mask, PC backplane; maximum power: 650W/㎡; input signal: USB, network port, etc.
显示屏面积可选800mm x 800mm到1536mm x 1536mm规格，满足不同路段的具体要求；亮度可选6500到15000nits，显示国标规定的红色、绿色和黄色汉字及图标。严格按照GBT 23828-2009标准选材、设计、生产和测试。该显示屏分两个区域，上排用于显示对向来车，下排用于显示本车超速。安装在急弯及特殊复杂路段，当对向来车时，本车道LED显示屏提示“对向来车”；当本车超速时则本车道LED显示屏提示“您已超速”，并启用延时程序10s。在没有超速和对向无来车时，则LED显示屏上下排显示“急弯道路、谨慎驾驶”，起到提示和预警作用。The display area can be selected from 800mm x 800mm to 1536mm x 1536mm to meet the specific requirements of different road sections; the brightness can be selected from 6500 to 15000nits, and it can display red, green and yellow Chinese characters and icons stipulated by the national standard. In strict accordance with GBT 23828-2009 standard material selection, design, production and testing. The display screen is divided into two areas, the upper row is used to display the oncoming vehicle, and the lower row is used to display the speeding of the vehicle. Installed on sharp bends and special complex road sections, when the oncoming vehicle, the LED display screen of this lane will prompt "opposite vehicle"; when the vehicle speeds up, the LED display screen of this lane will prompt "you have exceeded the speed", and the delay program will be activated for 10s . When there is no speeding and no oncoming traffic, the upper and lower rows of the LED display will display "sharp curve road, drive carefully", which plays a role of prompting and early warning.
雷达测速主要是利用多普勒效应(Doppler Effect)原理，当目标向雷达天线靠近时，反射信号频率将高于发射机频率；反之，当目标远离天线而去时，反射信号频率将低于发射机频率。如此即可借由频率的改变数值(目标面对雷达飞行，多普勒频率为正，当目标背向雷达飞行，多普勒频率为负)，计算出目标与雷达的相对速度。相关参数如下：静态测速范围：5～300km/h；环境要求：温度：-30度～+70度；湿度：0％～90％；微波频率：24.15GHz(K-band)；发射角：5度；直径：6.7cm、长：11.8cm；精确度：+/-1km/h。Radar speed measurement mainly uses the Doppler Effect (Doppler Effect) principle. When the target approaches the radar antenna, the frequency of the reflected signal will be higher than the frequency of the transmitter; conversely, when the target moves away from the antenna, the frequency of the reflected signal will be lower than that of the transmitter. machine frequency. In this way, the relative speed between the target and the radar can be calculated by changing the value of the frequency (the Doppler frequency is positive when the target is flying towards the radar, and the Doppler frequency is negative when the target is flying away from the radar). The relevant parameters are as follows: Static speed measurement range: 5 ~ 300km/h; Environmental requirements: temperature: -30 degrees ~ +70 degrees; humidity: 0% ~ 90%; microwave frequency: 24.15GHz (K-band); launch angle: 5 Accuracy; Diameter: 6.7cm, Length: 11.8cm; Accuracy: +/-1km/h.
该技术主要发挥两个作用，一是当汽车进入弯道时，雷达测试仪自动测出车速，并在LED显示屏提示“您已超速”，提醒司机必须减速；二是将来车信息传递对向司机，即对向车道LED显示屏显示“前方来车”，并启用延时程序10s；当自车没有超速和对向无来车时，则LED显示屏显示“急弯道路、谨慎驾驶”，起到提示和相互警示作用。This technology mainly plays two roles. One is that when the car enters a curve, the radar tester will automatically measure the speed of the vehicle, and the LED display will prompt "You have exceeded the speed" to remind the driver to slow down; The driver, that is, the LED display in the opposite lane displays "the car ahead", and activates the delay program for 10s; To prompt and mutual warning.
雷达测速仪分别在弯道行车道一侧设置t形杆件,横梁上安装雷达测速仪和补光灯，拍摄一个方向断面的图像。雷达测速仪与路面夹角不宜超过30度。要考虑路面车辆的高度和雷达测速仪探测的距离，t形杆件高低适宜，既不影响车辆通行，又在雷达测速仪的探测范围。横杆高度一般设置为4-8米。数据传输设备、处理器和供电设备安装在立柱上的机箱内。雷达测速仪检测到的车辆速度信息传输到处理器中，再将处理后的信息传输到弯道LED显示屏上。在实际设计中体现如下优点：系统设置灵活,安装简单,使用方便,不破坏路面，维修时不需封闭车道。The radar speedometer is installed on the side of the curved roadway with T-shaped rods, and the radar speedometer and supplementary light are installed on the beam to take images of a cross-section in one direction. The angle between the radar speedometer and the road should not exceed 30 degrees. To consider the height of the vehicle on the road and the detection distance of the radar speedometer, the height of the T-shaped bar is appropriate, which will not affect the traffic of the vehicle and is within the detection range of the radar speedometer. The height of the crossbar is generally set at 4-8 meters. Data transmission equipment, processors and power supply equipment are installed in the chassis on the column. The vehicle speed information detected by the radar speedometer is transmitted to the processor, and then the processed information is transmitted to the curve LED display. The following advantages are reflected in the actual design: flexible system setting, simple installation, convenient use, no damage to the road surface, and no need to close the driveway during maintenance.
