Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of traffic signal lights, and more particularly to a traffic signal light and a control method. BACKGROUND

[0002] Traffic signal lights are crucial management tools in urban road traffic, conveying instructions to pass or stop to passing vehicles and pedestrians. Traffic signal lights coordinate different directions of vehicle flow and pedestrian flow, guide vehicles and pedestrians to pass through the intersection safely, and reduce the occurrence of traffic accidents, ensuring the efficient and orderly operation of urban traffic.

[0003] In actual operation, traffic signal lights are exposed to the outdoors for a long time, and are subjected to wind and sun. The electronic components and circuits inside the lamp head are prone to aging, short circuit and other problems, which can cause damage to the lamp head of the traffic signal light. When the lamp head is damaged, it is often difficult to repair in time, and the traffic order at the intersection becomes chaotic, greatly increasing the probability of traffic accidents. In addition, in severe weather, such as foggy weather, the visibility of the entire city is greatly reduced. The light emitted by the traffic signal light becomes blurred in the fog, and the effect of road indication is not good, and people cannot accurately see the color and state of the signal light, thereby increasing traffic congestion and chaos. SUMMARY

[0004] The present application aims to overcome the defects of the prior art and provide a traffic signal light and a control method.

[0005] In order to achieve the above-mentioned purpose, the present application provides the following technical scheme: a traffic signal light comprising an outer box body, a control unit, a wireless communication unit and a plurality of inner box bodies, each inner box body is provided with a lamp head portion, the lamp head portion comprises a first lamp head, a second lamp head and a third lamp head distributed from bottom to top, the first lamp head, the second lamp head and the third lamp head each comprise three mounting surfaces, and each mounting surface is provided with one display lamp.

[0096] Working principle: the traffic signal of the application, a plurality of inner box bodies are installed in the outer box body, the inner box body is fixed to the outer box body, and the inner box body can be easily installed in the outer box body through the vertical limiting rail and the vertical limiting groove and the locking bolt. The lamp head part is installed in the inner box body, and a plurality of lamp head parts can be accurately positioned under the action of the movable protrusion and the limiting groove during use, so as to realize the stable installation of each lamp head body. And the corresponding display lamp is displayed through the light transmission plate.

[0097] Each lamp head body can be driven to rotate, the translation seat can be translated under the drive of the translation mechanism, so as to be located above the corresponding inner box body, and under the drive of the first, second and third electric telescopic rods, the first, second and third rotating cylinders can be driven to descend, so that the first, second and third rotating cylinders can rotate with the first, second and third rotating blocks, so as to drive the first, second and third lamp heads to rotate. Specifically, when the first lamp head needs to be driven to rotate, the first electric telescopic rod is elongated, so that the first rotating cylinder is lowered from the first rotating block to the downward sleeve of the first rotating block, then the first rotating cylinder is rotated under the drive of the first motor, so as to drive the first rotating block to rotate, thereby driving the first sleeve pipe with the first lamp head body to rotate (the first lamp head body can overcome the elastic force of the first spring when rotating, so as to overcome the rotation limit of the movable protrusion), and at this time, the second lamp head body and the third lamp head body will not rotate due to the limit of the movable protrusion. And when the translation seat is translated to the upper side of the two inner box bodies to prepare to drive the lamp head to rotate, the translation seat will extrude the movable seat, so that the movable seat is deviated to one side, so as not to hinder the rotation drive of the first, second and third rotating cylinders to the first, second and third lamp heads.

[0098] And the display lamps at the lamp head can be detected regularly, as shown in Figure 7 The lamp head is rotated by a certain angle, so that the display lamp at the mounting surface can be reflected by the reflector, and the reflected image is collected by the image acquisition unit, so that the display lamp can be judged according to the image. Three reflectors are located at three heights, and the lamp head body is driven to rotate, so that each height of the reflector can detect the display lamp of the three mounting surfaces at the corresponding lamp head body. For example, the first reflector is used for detection, the first lamp head body is driven to the first reflector by the first motor, so that the first motor is separated from the drive of the first lamp head body, and the image acquisition unit is driven to the upper side of the first reflector by the first motor, so as to realize the image acquisition of the display lamp of the first lamp head body through the first reflector. Two commonly used display lamps and one display lamp for severe weather are installed at each lamp head body, so that when one commonly used display lamp is damaged, another commonly used display lamp can be used instead.

[0099] In addition, weather information can be received through the wireless communication unit, and when bad weather is encountered, the bad-weather display lamps of the plurality of lamp heads can be made to face the rectangular through hole, thereby achieving traffic indication in bad weather.

[0100] The application also discloses a control method of the traffic signal lamp, and the control unit can control the traffic signal lamp to execute a detection state and a bad-weather display state.

[0101] In the detection state, the lamp head part of each inner box body is detected, the image acquisition unit is used to acquire the images of the three mounting surfaces of the first lamp head body through the first reflector, the image acquisition unit is used to acquire the images of the three mounting surfaces of the second lamp head body through the second reflector, and the image acquisition unit is used to acquire the images of the three mounting surfaces of the third lamp head body through the third reflector, so that when a certain display lamp for regular use is damaged, another display lamp for regular use can be used to indicate road traffic.
