The invention provides a traffic light emergency power supply system, which relates to the technical field of traffic light emergency power supply and comprises a traffic light group, a first capacitor group, a mains supply module, a power supply switching module, a first standby power supply, a second standby power supply and a third standby power supply. The power supply switching module switches the line to the first standby power supply to supply power to the traffic light group, after the power supply time of the first standby power supply reaches a first preset time threshold, the power supply switching module switches the line to the second standby power supply to supply power to the traffic light group, and after the power supply time of the second standby power supply reaches a second preset threshold, the power supply switching module switches the line to the second standby power supply to supply power to the traffic light group. The power supply switching module switches the line to a third standby power supply to supply power to the traffic light group; according to the invention, a centralized mode is adopted to supply power to the traffic light groups in the districts, so that the traffic light groups can operate for a long time after long-time power failure of the commercial power, and unified management of emergency power supply of the traffic lights in the urban districts is facilitated.

    本发明提出一种交通信号灯应急供电系统,涉及交通信号灯应急供电技术领域,包括交通灯组、第一电容组、市电模块、供电切换模块、第一备用电源、第二备用电源、第三备用电源,市电模块停电后,供电切换模块将线路切换至第一备用电源对交通灯组进行供电,在第一备用电源的供电时间达到第一预设时间阈值后,供电切换模块将线路切换至第二备用电源对交通灯组进行供电,第二备用电源的供电时间达到第二预设阈值后,供电切换模块将线路切换至第三备用电源对交通灯组进行供电;本发明采用的是集中式的方式对片区内的交通灯组进行供电,在确保交通灯组在市电的长时间停电后也能够长时间进行运作的同时,也便于城市片区中交通信号灯应急供电的统一管理。
