Description

Technical Field

[0001] The present invention relates to the technical field of traffic signal lamps, and more specifically, to a pedestrian crossing traffic signal lamp that is convenient for expansion and upgrading. Background Art

[0002] Pedestrian crossing traffic lights play a vital role in ensuring pedestrian safety. Pedestrian crossing traffic lights can regulate pedestrian behavior and reduce the occurrence of traffic accidents. At the same time, traffic lights can also improve road traffic efficiency and make traffic more orderly and smooth.

[0003] Existing pedestrian crossing traffic lights adopt a fixed design. Once the number and location of the signal light heads are determined, it is difficult to change or expand them. This limits the flexibility and adaptability of traffic signals, especially when it is necessary to increase signal light heads to cope with increased traffic flow or changes in traffic patterns. The entire signal light system needs to be redesigned or replaced, which is costly and time-consuming. Traffic signal light heads are exposed to the outdoor environment for a long time, and pollutants such as dust, dirt and bird droppings are easily accumulated, which affects the clarity of signal indications and makes it difficult for pedestrians to accurately judge traffic signals, thereby increasing the risk of traffic accidents. However, existing signal light heads are often difficult to clean and require professionals to use special equipment for maintenance, which is costly. In addition, due to the lack of an effective fault detection mechanism, existing traffic lights often cannot be discovered and handled in a timely manner when a fault occurs, which can easily lead to traffic chaos and safety hazards.

[0022] Furthermore, in the cleaning mode, when the light intensity is detected by the light intensity sensor, when the measured value is less than or equal to a set threshold, the control unit sends a signal indicating that maintenance is required.

[0023] If it is less than the set threshold, it means that the cleaning effect of the bar rotating plate is not good and the transparency is not enough, which means that the cleaning effect of the video acquisition unit and the signal light head is not good either.

[0024] In some embodiments, the control unit comprises a wireless communication unit.

[0025] Furthermore, a rear door panel is installed on the back panel of the cabinet.

There are multiple detection light sources 2.4 and light intensity sensors 4.8.

[0058] Working principle: The control unit can control the traffic light to execute the use mode, cleaning mode and detection mode. As shown in the figure, in the use mode, the top of the sliding door panel is located below the lowest signal lamp head; at this time, the sliding door panel blocks the installation holes at the upper door panel, so as to use as many signal lamp heads as needed, and the uninstalled installation holes can be blocked by the sliding door panel, and the installation holes here reserve upgrade space for the subsequent addition of new signal lamp heads. The signal lamp head can choose the required signal lamp head type, such as pedestrian traffic lights, cycling traffic lights, countdown lights, etc.

[0059] In the cleaning mode, the top of the sliding door panel is abutted against the top block, and the cleaning liquid in the water tank is first pumped by a liquid pump and cleaned by a nozzle, so that the cleaning liquid can clean the strip rotating plate, the video acquisition unit, and each signal lamp head (a holding space is formed between the holding bottom plate and the holding back plate, and the waste liquid after cleaning will be collected by the holding space and enter the water tank, and can be recycled after being filtered by the filter unit), and then the fan unit and the heating unit are used to perform jet drying, so as to achieve rapid drying of the cleaning liquid, and then the detection light source is turned on, and the light intensity is detected by the light intensity sensor. When the measured value of the light intensity sensor is greater than the set threshold, it means that the cleaning effect of the strip rotating plate is better and has better light transmittance, which means that the cleaning effect of the video acquisition unit and the signal lamp head is also better. Otherwise, it means that the cleaning effect is not good and maintenance is required, such as the need to replace the cleaning liquid.

[0060] In the detection mode, the driving motor drives the sliding door panel to rise and fall, and uses the light intensity sensor to detect the light intensity facing the signal lamp head, so that the light intensity measurement value of each signal lamp head in the entire height direction can be compared with the light intensity measurement value when the signal lamp head is working normally, so as to determine whether the signal lamp head is working normally.
