技术领域Technical Field
本实用新型涉及道路交通安全技术领域，具体涉及一种用于道路斑马线的预警装置。The utility model relates to the technical field of road traffic safety, in particular to an early warning device for zebra crossings on roads.
背景技术Background technique
道路路口是交通事故的高发点，在道路交通事故中，行人属于“易受伤害群体”，受伤的程度远远高于机动车司乘人员。发生交通事故的原因有很多，例如行人不遵守交通规则，过马路时不注意来往车辆；驾驶者没有礼让行人；驾驶者受恶劣天气、光照不足、斑马线受损等原因影响，未及时注意到行人，躲避不及；驾驶员因视线不足、夜间行车速度较快、身体疲劳警觉性降低等原因无法及时避让行人。为减少交通事故的发生，道路路口通常会设置静态警示标志或安装减速带来对行人车辆进行警示，但这些方式警示效果有限，例如在恶劣天气等环境下，警示标志仍容易被忽略，无法很好的起到预防交通事故的目的。另外在非信号控制路口及路段，为保障车辆的流速，交通安全引导设施及标志设置较少，进一步降低了警示效果。因此需要一种不受环境影响、警示效果好的道路斑马线预警装置。Road intersections are high-incidence points for traffic accidents. In road traffic accidents, pedestrians belong to the "vulnerable group" and the degree of injury is much higher than that of motor vehicle drivers and passengers. There are many reasons for traffic accidents, such as pedestrians not abiding by traffic rules and not paying attention to oncoming vehicles when crossing the road; drivers not giving way to pedestrians; drivers not noticing pedestrians in time and avoiding them due to bad weather, insufficient lighting, damaged zebra crossings, etc.; drivers are unable to avoid pedestrians in time due to insufficient vision, high speed at night, physical fatigue and reduced alertness. In order to reduce the occurrence of traffic accidents, static warning signs or speed bumps are usually set up at road intersections to warn pedestrians and vehicles, but these methods have limited warning effects. For example, in environments such as bad weather, warning signs are still easily ignored and cannot effectively prevent traffic accidents. In addition, at non-signal controlled intersections and sections, in order to ensure the flow rate of vehicles, fewer traffic safety guidance facilities and signs are set, which further reduces the warning effect. Therefore, a road zebra crossing warning device that is not affected by the environment and has a good warning effect is needed.

1、 本实用新型能够对车辆靠近路口、行人靠近路口以及车辆行人同时靠近路口处的多种情况进行检测预警，预警方式为在检测到车辆和行人时发射激光，相对于静态警示牌或常亮警示灯等警示方式，在有行人和车辆靠近时触发的警示方式能够使行人和驾驶员更容易得到提醒，且激光能够在恶劣天气或光照不足的环境下仍具备较好的照射效果，警示效果好。1. The utility model can detect and warn of various situations such as vehicles approaching intersections, pedestrians approaching intersections, and vehicles and pedestrians approaching intersections at the same time. The warning method is to emit lasers when vehicles and pedestrians are detected.

The utility model detects pedestrians and vehicles through millimeter-wave radar and microwave radar. Compared with detection equipment such as cameras, millimeter-wave radar and microwave radar are not affected by environmental conditions such as weather and light, and have good detection effects, which can effectively avoid the situation where the detection equipment fails to detect due to environmental reasons, resulting in the failure of the early warning device.
3、 本实用新型可通过激光灯照射、提示语显示、爆闪灯闪烁、语音播报等多种警示方式的组合进行预警，提高了警示效果，能够进一步避免驾驶员或行人因注意力不集中、疲劳等原因未注意到预警而导致的交通事故。3.

具体的，所述主壳体8内设有通信组网模块，控制模块通过通信组网模块信号连接有云控平台，管理人员可以通过云控平台查看预警装置信息和进行设置。Specifically, a communication networking module is provided in the main housing 8, and the control module is connected to the cloud control platform through the communication networking module signal. The management personnel can view the early warning device information and perform settings through the cloud control platform.
预警装置可应用于图3和图4所示的两种场景，一是安装在直行车道上有斑马线的情况，可检测来车方向的直行车辆，二是安装在十字路口处，可检测来车方向的直行车辆或右转车辆。The early warning device can be applied to the two scenarios shown in Figures 3 and 4. One is to be installed on a straight lane with a zebra crossing to detect oncoming straight vehicles. The other is to be installed at an intersection to detect oncoming straight vehicles or right-turning vehicles.
工作过程：平时预警装置处于休眠状态，激光灯组模块3不亮，当毫米波雷达探测到行人即将进入斑马线时，将信号发送给控制模块；或者当微波雷达监测到有车辆从来车方向即将进入斑马线一定距离内，将信号发送给控制模块；或者雷达监测到同时有来车和行人时，将信号发送给控制模块；Working process: Usually the warning device is in dormant state, and the laser light module 3 is off. When the millimeter wave radar detects that a pedestrian is about to enter the zebra crossing, it sends a signal to the control module; or when the microwave radar detects that a vehicle is about to enter the zebra crossing within a certain distance from the oncoming direction, it sends a signal to the control module; or when the radar detects that there are both oncoming vehicles and pedestrians, it sends a signal to the control module;

After receiving the data such as distance, speed and angle transmitted by the detection device, the control module compares the data with the set threshold value; when a pedestrian enters a specific area less than or equal to 6 meters away from the zebra crossing, or when a vehicle enters a specific area less than or equal to 200 meters away from the zebra crossing from the direction of the oncoming vehicle, the control module starts the intelligent warning system in an asynchronous or synchronous manner. The specific steps include: the control module controls the laser light group module 3 to start emitting lasers, and the two LED display screens respectively display texts to prompt pedestrians and drivers, and send a command to play a prompt voice to the voice alarm module 7. The voice alarm module 7 plays the prompt voice and starts the signal light timing module 6 at the same time. The signal light timing module 6 displays the traffic signal and starts the countdown. When the countdown ends, the control module sends a stop command to the intelligent warning system and waits for the next warning work.
