本發明係主張台灣專利申請案第110102643號(申請日:2021年01月25日)之國內優先權,該申請案之完整內容納入為本發明專利說明書的一部分以供參照。 The present invention claims the domestic priority of Taiwan Patent Application No. 110102643 (application date: January 25, 2021), and the complete content of the application is incorporated as a part of the patent specification of the present invention for reference.
本發明涉及一種交通及行人交通號誌,特別是涉及一種設置於道路的行人穿越道的具有智慧偵測及警示功能的號誌系統。 The invention relates to a traffic and pedestrian traffic signal, in particular to a signal system with intelligent detection and warning functions arranged on a pedestrian crossing of a road.
現有的道路交通號誌中,通常使用號誌控制器控制一行人號誌裝置和行車號誌裝置,其中行人號誌裝置能夠顯示用以管制行人穿越道通行狀態的燈號(例如:紅燈及綠燈燈號),而行車號誌裝置則和行人號誌裝置連動,在行人號誌裝置顯示綠燈燈號時,行車號誌裝置則顯示紅燈以禁止車輛闖越行人穿越道,以維護行人安全。 In the existing road traffic signals, a signal controller is usually used to control a pedestrian signal device and a traffic signal device, wherein the pedestrian signal device can display lights used to control the state of a crosswalk (for example: red lights and Green light signal), while the traffic signal device is linked with the pedestrian signal device. When the pedestrian signal device displays a green light signal, the traffic signal device displays a red light to prohibit vehicles from crossing the pedestrian crossing to maintain pedestrian safety. .
現有的交通號誌僅是單純使用顯示燈號來管制車輛或行人的通行狀態,因此對於車輛或行人違規不遵守交通號誌的行為無法進行管制或警告。並且現有交通號誌顯示紅燈或綠燈的時間是固定的,無法依照行人穿越道上人流的實際情形進行調整。並且現在因為智慧型手機的普及,低頭族與日俱增,行人常常未注意到行人號誌裝置是紅燈狀態,而進入行人穿越道, 造成危險,而現有的交通號誌無法達到提醒和警示行人的效果。 Existing traffic signals only use light signals to control the passing status of vehicles or pedestrians, so it is impossible to control or warn vehicles or pedestrians who do not obey the traffic signals. And the time that existing traffic signal shows red light or green light is fixed, can't adjust according to the actual situation of the flow of people on the crosswalk. And now because of the popularization of smart phones, the number of people who bow their heads is increasing day by day. Pedestrians often enter the crosswalk without noticing that the pedestrian signal device is in a red light state. Cause danger, and existing traffic signal can't reach the effect of reminding and warning pedestrians.
現有一部分交通號誌嘗試著使用攝像裝置擷取交通閘道的影像,且透過影像辨識手段辨識車流或人流,用來作為號誌系統控制切換顯示燈號,或調整顯示燈號時間的依據。然而現有的影像辨識手段容易因為天候因素,如大雨,而影響辨識準確度,造成誤動作。 At present, some traffic signals try to use camera devices to capture images of traffic gateways, and use image recognition methods to identify traffic flow or people flow, which is used as a basis for the signal system to control switching and displaying lights, or to adjust the time of displaying lights. However, the existing image recognition methods are likely to affect the recognition accuracy due to weather factors, such as heavy rain, and cause malfunctions.
於是,本發明人認為上述缺陷可改善,乃特潛心研究並配合科學原理的運用,終於提出一種設計合理且有效改善上述缺陷的本發明。 Therefore, the inventor believes that the above-mentioned defects can be improved, Naite devoted himself to research and combined with the application of scientific principles, and finally proposed an invention with reasonable design and effective improvement of the above-mentioned defects.

In this embodiment, the
所述第一偵測區域A1和所述第二偵測區域A2分別涵蓋所述行人穿越道3兩側的入口端位置,以及接近所述行人穿越道3中央位置的區域。為便於說明起見,所述第一偵測區域A1和所述第二偵測區域A2靠近所述行人穿越道3的入口端的一端定義為起始端A101、A201,而所述第一偵測區域A1和所述第二偵測區域A2遠離所述行人穿越道3的兩入口端的一端定義為末端A102、A202,而在所述第一偵測區域A1和所述第二偵測區域A2內行走的行人P朝向所述末端A102、A202方向行走的行進方向定義為遠離方向,而所述第一偵測區域A1和所述第二偵測區域A2內行走的行人P朝向所述起始端A101、A201行走的方向定義為近接方向。
The first detection area A1 and the second detection area A2 respectively cover the entrance positions on both sides of the

The
本發明配置為具有一闖紅燈警示機制,所述闖紅燈警示機制,為當所述行人號誌裝置120顯示紅燈狀態下,所述第一偵測模組200或所述第二偵測模組300偵測到有行人跨越人行道邊界而跨入所述第一偵測區域A1或所述第二偵測區域A2時,能夠透過所述輔助警示裝置160顯示一第一警示訊息,而警告行人勿闖紅燈。此外,本發明所述紅燈警示機制當中,能夠在偵測到行人闖越紅燈的狀態下,透過所述輔助照明裝置170發出閃爍光線或連續光線照射於所述行人穿越道3,以警示行人勿闖紅燈。
The present invention is configured to have a warning mechanism for running a red light. The warning mechanism for running a red light is that when the
本發明所述紅燈警示機制當中,還能夠配置為當所述第一偵測模組200偵測到有行人進入到所述第一入口警示區A11內有行人P時,能夠透過所述輔助警示裝置160發出一第二警示訊息,所述第二警示訊息用以提醒所述第一入口警示區A11內的行人退後,以避免行人P停等紅燈時過於靠近馬路2,以避免發生危險。

更詳細地說,本發明所述具有智慧偵測及警示功能的號誌系統1的所述綠燈秒數延長機制,是以在所述第一偵測區域A1範圍內朝向所述遠離方向行走的所述行人P以正常速度通過所述行人穿越道3所需的時間為基準,決定所述第一臨界時間。換句話說,當所述綠燈剩餘秒數低於所述第一臨界時間的狀態下,若所述第一偵測模組200偵測到在所述第一偵測區域A1內仍有朝向所述遠離方向行走的行人P,代表在所述行人P在到達所述第一臨界時間時尚未離開所述第一偵測區域A1,因此能夠判斷所述行人P無法在所述行人號誌裝置120顯示的綠燈燈號結束前通過所述行人穿越道3,因此透過延長所述行人號誌裝置120顯示綠燈的秒數的手段,以確保行人P有充分時間通過行人穿越道3。
More specifically, the green light second extension mechanism of the
本發明所述具有智慧偵測及警示功能的號誌系統1還配置為具有一綠燈穿越警示機制,所述綠燈穿越警示機制為當所述行人號誌裝置120顯示燈號為綠燈,且所述行人號誌裝置120的所述綠燈剩餘秒數小於一第二臨界時間時,所述第一偵測模組200偵測出有行人要從所述第一入口警示區A11進入到所述行人穿越道3時,能夠透過所述輔助警示裝置160發出一警示訊息以提醒進入到所述第一入口警示區A11的行人停止前進,並等候下一次綠燈燈號
再通過行人穿越道3。
The
更詳細地說,所述第二臨界時間是以行人以正常速度行走通過所述行人穿越道3所需時間為基準,也就是說,當所述綠燈剩餘秒數低於所述第二臨界時間時,代表此時正要進入所述行人穿越道3的行人無法在綠燈結束前通過行人穿越道3。所述第一偵測模組200能透過所述第一攝像裝置210擷取的影像辨識出是否有行人進入到所述第一入口警示區A11內,且透過所述第一雷達裝置220判斷所述第一入口警示區A11內的行人是要離開所述第一入口警示區A11,或者是要從所述第一入口警示區A11進入到所述行人穿越道3。
In more detail, the second critical time is based on the time required for pedestrians to walk through the
本實施例中,在所述綠燈穿越警示機制中,是透過所述輔助警示裝置160以圖像訊息或文字訊息,並以語音訊息為輔佐,而提示行人目前綠燈剩餘秒數不足以供行人通過行人穿越道3,並且指示行人等待下一次綠燈燈號再行通過行人穿越道3。
In this embodiment, in the warning mechanism for crossing the green light, the
此外,如圖8及圖9所示,本發明的所述第一偵測模組200和所述第二偵測模組300能夠連接至一控制設備400,所述控制設備400能夠為具有顯示單元410的電腦或資訊設備。所述顯示單元410能夠顯示出一控制畫面,操作者能夠透過所述控制畫面控制所述第一偵測模組200和所述第二偵測模組300的所述第一偵測區域A1、所述第二偵測區域A2、和所述第一入口警示區A11、所述第二入口警示區A21的範圍。
In addition, as shown in FIG. 8 and FIG. 9, the
更詳地說,如圖9所示,所述控制設備400的所述顯示單元410能夠顯示出一控制畫面,所述控制畫面包含有所述道路2及行人穿越道3的影像或圖像,操作者能夠透過指標設備(如:鼠標)在所述控制畫面上點選多個控制點411、412、413、414,而圈選出所述第一偵測區域A1、第二偵測區域A2、以及所述第一入口警示區A11、第二入口警示區A21的範圍。

[實施例的有益效果] [Advantageous Effects of Embodiment]
本發明的其中一有益效果在於,本發明的第一偵測模組和第二偵測模組分別透過影像辨識手段和雷達偵測手段偵測所述第一偵測區域和第二偵測區域內的行人及其行進方向,而能夠在紅燈狀態下辨識是否有行人闖越紅燈,或者是在綠燈剩餘秒數低於臨界秒數的情形下辨識第一偵測區域和第二偵測區域內是否仍有行人,以及第一偵測區域和第二偵測區域內行人的行進方向,以判斷行人是否有足夠時間通過行人穿越道。 One of the beneficial effects of the present invention is that the first detection module and the second detection module of the present invention respectively detect the first detection area and the second detection area through image recognition means and radar detection means Pedestrians and their direction of travel can be identified in the red light state, whether there is a pedestrian crossing the red light, or the first detection area and the second detection area can be identified when the remaining seconds of the green light are less than the critical number of seconds Whether there are still pedestrians in the area, and the direction of travel of the pedestrians in the first detection area and the second detection area, to determine whether the pedestrians have enough time to pass through the crosswalk.
本發明透過上述技術方案,能夠結合影像辨識手段和雷達量測手段,因此不需使用複雜的運算便能夠準確而快速辨識出所述第一偵測區域和所述第二偵測區域內是否有行人,以及所述行人的行進方向,同時能夠更為快速地判斷出行人穿越道上行人的位置及行進方向。 Through the above-mentioned technical solution, the present invention can combine the image recognition means and the radar measurement means, so it can accurately and quickly identify whether there is an object in the first detection area and the second detection area without using complex calculations. Pedestrians, and the direction of travel of the pedestrians, and at the same time, the position and direction of travel of pedestrians on the pedestrian crossing can be judged more quickly.
