The invention relates to the field of traffic signal lamp fault detection, in particular to a fault detection device capable of being remotely controlled. The detection device is connected to a traffic signal controller, comprises a plurality of groups of detection interfaces, a working circuit and an energy storage battery, judges whether a current intersection signal lamp has a fault or not through monitoring data changes, and makes a response: when a power failure occurs, the detection device automatically switches the energy storage battery to supply power, and detects that the fault reaches a certain time length, and the detection is finished. The working circuit reports a fault, and an energy storage battery can be switched through a remote command to temporarily supply power to the traffic signal lamp; when the timing fault occurs, the fault is detected to reach a certain time length, the working circuit reports the fault, and the timing of the signal machine can be adjusted by remotely writing a command; and when other faults occur, the fault detection reaches a certain duration, and the working circuit reports the faults and uploads abnormal data. According to the invention, the influence of the fault of the traffic signal lamp on road traffic is reduced, the fault repair efficiency is improved, and the convenience of timing adjustment of the signal lamp is improved.
本申请涉及交通信号灯故障检测领域,尤其涉及一种可远程控制的故障检测装置。所述检测装置连接在交通信号控制机上,包括多组检测接口、工作电路和储能电池,通过监测数据变化判断当前路口信号灯是否存在故障,并做出反应:断电故障时,所述检测装置自动切换储能电池供电,检测故障达到一定时长,工作电路上报故障,且可通过远程命令切换储能电池临时为交通信号灯供电;配时故障时,检测故障达到一定时长,工作电路上报故障,且可通过远程写入命令调整信号机配时;其他故障时,故障检测达到一定时长,工作电路上报故障,并上传异常数据。本申请降低了交通信号灯出现故障对道路交通造成的影响,提升了故障修复效率,提升了信号灯配时调整的便利性。
