Description
本发明属于道路交通安全领域，尤其涉及道路状态信息接收处理技术领域。 The invention belongs to the field of road traffic safety, and in particular relates to the technical field of road state information receiving and processing.
汽车经过红绿灯路口时经常会遇到前方有大车，诸如公交车、土方运输卡车、大货车等较高的车辆，从而挡住了后续跟进车辆的视线，导致后续跟进车辆无法判断前方路口的信号灯实际状态，跟进车辆很容易在大车后面闯红灯，如果等大车先行通过可以看到信号灯后再通过路口，势必又会造成路口阻塞的现象，另外还有就是恶劣天气诸如大雾大雨或者强烈逆光等情况下无法看清信号灯时也很容易闯红灯，总之，在通过路口时无法在车辆中同步知悉红绿灯的状态，以及目前患有色盲或者色弱的人士无法成为驾驶员，也是由于无法分辨信号灯的状态所导致，为了解决上述问题，现有的专利文献中有几种解决方式，例如号码为：
201010190885 、 201020584377
的专利申请公开文件，均提出了解决上述技术问题的技术方案，但是，这些技术方案中对于红绿灯信号发射端与车辆内所载的接收端之间的联系方式均未公开可实施的具体方案，只是简单的描述了'发射装置将红绿灯信号发送给车载的接收装置'，而在实际的使用过程中，十字路口具有至少四个方向灯光指示，考虑到信号接收的问题，横向行进的车辆如果收到纵向的灯光信号，并以纵向灯光信号为行进参考，反而容易导致车辆发生闯红灯的情形，此信号发生混乱的问题在上述专利文献中并没有得到具体的解决方案，问题的关键点是无法定义行进车辆的运动方向与需要受指挥的信号灯的对应，故此上述文献并无法真正的解决现有技术中所存在的技术问题，为了解决上述问题，申请人邀请电子通讯及软件领域的专业人士进行沟通交流，通过交流后对上述问题大家所提出的解决方案有以下几种，
1
，在道路停止线附近建立发射装置，将发射装置的发射方向固定向一个来车方向发射信号，利用发射装置的信号强弱的特性，使区域内的车辆能够准确接收到信号灯的状态信号；
2 将信号灯通过反射装置反射到车辆能够看到的角度；上述几种方案虽然能够解决上述技术问题，但是，第 1
种方案存在两个问题，一是角度调节，二是道路特殊情况下角度会发生混淆；第 2
中方案存在的问题是反射装置的建设不能做到满足来车方向每辆车辆的视角，仍然存在死角问题 ;
故此，经过本领域的相关技术人员进行探讨研究后仍然没有找出一个更好的成本较低的解决方案，问题仍然无法解决。另外，还需要补充一个实际问题，驾驶员在临近路口时，由于车辆的遮挡，一般情况无法看到前方的导流线的分布，也就是说，无法提前预知究竟有多少左转车道和直行车道，故此很容易发生驾驶员进入导流通道后再跨实线违章进行便道的事情，也容易引发擦碰及堵塞。
When passing through a traffic light intersection, cars often encounter large vehicles in front of them, such as buses, earth-moving trucks, and large trucks, which block the sight of the follow-up vehicles, and the follow-up vehicles cannot judge the intersection ahead. The actual state of the signal light, it is easy to follow the vehicle and red light behind the big car. If the big car passes before you can see the signal light and then pass the intersection, it will inevitably cause the intersection to block, and there is also bad weather such as heavy fog or heavy rain. In the case of strong backlighting, it is easy to see the red light when the signal light is not visible. In short, it is impossible to know the status of the traffic light in the vehicle when passing the intersection, and the person who is currently suffering from color blindness or color can not become the driver, and because the signal light cannot be distinguished. In order to solve the above problems, there are several solutions in the existing patent documents, for example, the number is:
201010190885, 201020584377
The patent application publications all propose technical solutions to solve the above technical problems. However, in these technical solutions, no specific implementation schemes are disclosed for the connection manner between the traffic signal transmitting end and the receiving end contained in the vehicle. It simply describes the 'transmitting device sends the traffic light signal to the receiving device on the vehicle'. In actual use, the intersection has at least four directions of light indication. Considering the problem of signal reception, if the vehicle is traveling laterally, The longitudinal light signal and the vertical light signal are the reference for the travel, but it is easy to cause the vehicle to emit a red light. The problem of this signal confusion is not solved in the above patent documents. The key point of the problem is that it cannot be defined. The moving direction of the traveling vehicle corresponds to the signal light that needs to be directed. Therefore, the above documents cannot truly solve the technical problems existing in the prior art. In order to solve the above problem, the applicant invites professionals in the field of electronic communication and software to communicate. Exchange, after the exchange, the above The problems that everyone has proposed are as follows.
1
A transmitting device is established near the road stop line, and the transmitting direction of the transmitting device is fixedly transmitted to an incoming vehicle direction, and the signal strength of the transmitting device is utilized to enable the vehicle in the region to accurately receive the status signal of the signal light;
2 Reflect the signal light through the reflector to the angle that the vehicle can see; although the above several solutions can solve the above technical problems, but the first
There are two problems in the scheme, one is the angle adjustment, and the other is the confusion of the angle in the special case of the road; the second
The problem with the medium scheme is that the construction of the reflecting device can not meet the perspective of each vehicle in the direction of the incoming vehicle, and there is still a problem of dead angle;
Therefore, after research and discussion by relevant technical personnel in the field, a better and lower cost solution has not been found, and the problem cannot be solved. In addition, it is necessary to add a practical problem. When the driver approaches the intersection, due to the occlusion of the vehicle, the distribution of the front guide line cannot be seen in general. That is, it is impossible to predict in advance how many left and straight lanes there are. Therefore, it is easy for the driver to enter the diversion channel and then carry out the access road across the solid line, and it is easy to cause rubbing and blockage.
