The invention relates to an energy-saving parking space indication method in the field of road traffic and intelligent traffic. According to the energy-saving parking space indication method, a devicecomprises a red light position electromagnet, a green light position electromagnet, a rack with a limiting notch, a reflective ball with a reflective film and a coaxial gear, a pin and the like, wherein red and green reflective films are respectively adhered to two hemisphere regions on the surface of the reflective ball. When an idle state of the parking space is changed, an external parking space detection system energizes the traffic light electromagnet to attract the rack to move, drives the reflective ball and the coaxial gear to rotate, drives the reflective ball to rotate synchronously, enables the hemispherical surface with the reflective film in the corresponding color to face vehicles coming and going, generates reflection by means of garage illumination and illumination of headlamp light of the vehicles coming and going, and shows different colors to indicate whether the parking space is idle or not. Compared with an existing parking space indicating method adopting continuous power supply, power supply is not needed in most of the whole day, the parking space state is indicated through passive light reflection of ambient light, the electromagnet is energized only at the moment when a vehicle enters and exits the parking space, the reflective ball is triggered to rotate to change display, and electric energy loss can be greatly reduced.

    本发明涉及道路交通和智能交通领域的一种节能型车位指示方法。根据所述方法装置包括红灯位电磁铁、绿灯位电磁铁、带限位缺口的齿条、带反光膜和同轴齿轮的反光球、销钉等组成。反光球表面的两个半球区域分别贴红色、绿色反光膜。当车位空闲状态改变时,外接车位检测系统给红绿灯位电磁铁通电励磁吸引齿条移动,带动反光球同轴齿轮旋转,反光球同步旋转,将相应颜色反光膜的半球面朝向往来车辆,依靠车库照明和往来车辆前照灯光的照射产生反射,呈现不同颜色表示车位是否空闲。和现有采用持续供电的车位指示方法相比,本发明在全天绝大部的时间无须供电,依靠环境光线反射被动发光指示车位状态,仅在车辆进出车位的瞬间给电磁铁供电,触发反光球旋转改变显示,可大幅减少电能损耗。
